Dave's 280z VK56DE Project


Recommended Posts

Hey guys,

 

Just picked up my first LHD car.

 

Its a 1978 280Z, with the fugly bumpers, 14" centrelines, and a rear window louvre, which will be replaced with nothing, 16x8 sportmax 002s, and nothing respectively.

 

Good to be driving a zed again, though I must say, its slow as ♥♥♥♥.

 

Plans are to keep it a daily, with a few handling/braking modifications as time/money permits. So some decent springs, shocks, general maintenance stuff, and maybe some decent rotors/calipers down the track. :)

 

Dave

Guys,

 

I'm in the middle of doing the P30-0032 bilstein upgrade, and switching to coil-overs on my 280z. I just thought I'd document what I've done so far here.

 

 

The parts:

 

From A1 Racing: (http://shop.a1racing.com/)

- Threaded Alu sleeves: 4 x COK12452-H @ USD18.80 ea

- Lower spring perch/nut: 4 x COK12460-B8 @ USD12.87 ea

- Coil-over top: 4 x COK12465 @ USD13.08 ea

 

From MJMAutoHaus: (http://www.mjmautohaus.com/catalog/product_info.php?cPath=2_12_37_71_293_4710&products_id=1995)

- Bilstein P30-0032 shocks: 2 x P30.0032.SET @ USD199.95 ea

 

From SummitRacing:

- Front QA1 10" 275lb/in springs: 2 x HAL-10-275 @ USD37.88 ea

- Rear QA1 10" 250lb/in springs: 2 x HAL-10-250 @ USD38.88 ea

 

From Motion Industries: (https://www.motionindustries.com/mot.../mi/motion.jsp)

- 28mm OD, 15mm ID bearing: 2 x FNT 1528 BRG @ USD3.49 ea

- 28mm OD, 15mm ID thrust washer: 2 x LS1528 @ USD7.62 ea

 

From Reid Supply: (http://reidsupply.com/detail.aspx?R=DM-14028&ST=Drill%20Bushings)

- 22mm OD, 14mm ID drill bushing: 2 x DM-14028 @ USDnotmuch

 

 

The tools:

 

This assumes a general toolkit with appropriate spanners, sockets, drives and ratchets. Additionally helpful is:

- bench vice

- angle grinder with cutting and grinding discs

- large pipe cutter (I got one that does up to 2-1/8")

- 1" drill bit (had to order online)

- 13mm or 1/2" drill bit

- M14x1.5 tap

- half round file

- hack saw

- welder

 

 

The procedure:

 

Preparation:

 

Step 1. Remove front strut. Make sure you loosen, but do not remove(!) the top damper nut while the assembly is in the car as its much easier to hold.

 

Step 2. Remove the top damper nut. The stock 280z assembly is preloaded so it explodes as the nut comes loose. So don't be sitting there looking directly down at it.

 

Step 3. Using multigrips (aka channel locs), undo the damper gland nut and remove the existing insert/original body.

 

Step 4. Bolt the assembly into a vice of some sort to make it easier to work with. You can remove the brakes to make it lighter but I was too lazy.

step4-in-vice.jpg

 

 

Strut-tube Modification:

 

Step 5. Using a thin cutting disc on an angle grinder, cut the stock lower spring perch off. Do not cut into the strut body, I cut 6mm (1/4") above the weld to get enough distance.

step5-cutting.jpg

step5-cut.jpg

 

[/u] Step 6. Using a grinding disc, grind down the remaining spring perch and weld until it is flat and the threaded sleeve can easily slide past where the weld was.

step6-grinding.jpg

step6-ground.jpg

step6-done.jpg

 

Step 7. Slide the threaded sleeve down until the top of it is 2-1/4" down from the top. Scribe a mark around the entire circumference of the strut tube using the top of the threaded sleeve as a guide. Remove the threaded sleeve.

step7-in-place.jpg

step7-scribe.jpg

 

Note: Don't worry, you are not going to be shortening the struts 2-1/4". The female carrier that comes with the Bilstein dampers will be welded onto the strut tube, adding an extra 3/4". So we are taking 1-1/2" out.

The reason this is done instead of sectioning the struts in the typical fashion is that Bilstein do not make a gland nut in the M52x1.5(?) thread to suit the 280z struts, so we use the female carrier that comes with them instead.

 

Step 8. Using the cutting disc, cut anywhere between 1/2 and 1" off the end of the strut. This does not have to be particularly neat, a few mm difference is acceptable. You will be using this off-cut later to stop the threaded sleeve sliding down.

step8-marked.jpg

 

Step 9. Cut the strut tube at the mark scribed in step 7 using the pipe cutter.

step9-pipe-cutter.jpg

step9-cut.jpg

 

Advice: on the first orbit of the tube, watch the cutting wheel very closely to ensure it follows the scribe precisely. If it does not meet up with itself it will tend to try and work its way down the tube cutting a very shallow thread. Do a few orbits in between tightening the pipe cutter.

 

Step 10. Cut the cut-off from step 8 into three equal concave shaped sections (roughly every 120 degrees).

step10-thirds.jpg

 

Step 11. Put the cut-off from step 9 into the vice and individually beat each of the three concave shells until they fit nicely against the outside of the tube.

step11-third-hammering.jpg

step11-third-hammered.jpg

 

 

Female Carrier Modification:

 

Step 12. Using the cutting disc, cut off the smaller diameter section (on which the PN is stamped) of the female carrier. Do not overcut into the conical (tapered) section.

step12-cut-off.jpg

 

Step 13. Using the grinding disc, carefully grind down the remaining small diameter section until the carrier ends at the end of the conical section.

step13-grind-down.jpg

step13-shorten-carrier.jpg

 

Step 14. Using the round file, file the inside of the carrier down until the damper body can fit through it easily.

step14-file-out-carrier.jpg

step14-damper-through-carrier.jpg

 

Advice: use the internal steps as a guide as to how far you have filed.

 

 

 

Coil-over-top Modification:

 

Note: Unfortunately, the coil over tops I ordered from A1 racing are clearly not meant to suit the P30 bilstein damper. They require very minor modification.

 

Step 15a. Place the Torrington thrust washer on top of the coil over top and grind down the coil over top until they are both level.

step15a-grindtopdown.jpg

 

Step 15b. Cut the drill bushing into 4 10mm long sections. These spacers centre the coil over top on the Bilstein damper. By making them a little longer than the thickness of the coil over top section, means that when installed the section clamps down while leaving the coil over top free to rotate on the torrington bearings, and keep the steering nice and light.

 

 

Strut-top Modification:

 

Step 16. Put the strut-top in a vice, and using a stanley knife, trim the downwards-protruding rubber lip off 6mm (1/4").

step16-trim-rubber.jpg

 

Step 17. Using a 13mm (or 1/2") drill bit, drill out the D in the strut-top.

step17-strut-top-drill.jpg

 

Step 18. Using the M14x1.5 tap, tap the hole in the strut-top. This, while perhaps not absolutely necessary, prevents the threads on the damper from being damaged by pressing against the metal in the strut-top during side loading. This helps hold the damper piston stable whilst doing up the top nut later. Additionally, it simplifies preloading the spring, as the top can simply be wound on an inch, providing around 275lb without necessitating spring compressors.

step18-strut-top-tap.jpg

 

 

Welding:

 

Step 19. Get some 1-1/4" OD Alu pipe from which to make the spacers. I initially tried 1 1/2" but it was just a fraction too big to fit through the carrier. On my struts the fronts needed a spacer 9/16" long. Don't forget to test the assembly to ensure the spacer length is good. The gland nut should go solid with between 1 and 2 threads showing. Additionally, this locates the strut housing neatly in the carrier, and should provide additional lateral support.

 

Step 20. Tack-weld two opposing sides (12 o'clock and 6 o'clock) of the female carrier onto the strut. Slide the threaded sleeve down to check that the top of the female carrier is even with the top of the gland nut all the way around. Tap with a hammer and/or re-tack as necessary to get this correct. Slide the threaded sleeve off.

 

Step 21. Weld the female carrier onto the strut body.

 

Step 22. Grind the new weld down to the tube OD until the threaded sleeve can slide on again.

struts-grinding.jpg

 

Step 23. Position the threaded sleeve so it is flush with the top of the carrier. Tack the three concave shells from step 10 at even intervals around the tube at the bottom of the threaded sleeve. Put the side of the shell with the thread against the sleeve as this side was the former strut top, and is perfectly flat around.

step23-tack_shells.jpg

 

Step 24. Slide the threaded sleeve off and weld the shells onto the tube in the lower and vertical sides. Do not weld the top as this flat step is what we want.

step24-weld_shells.jpg

 

Step 25. Splash some paint on the cleaned up struts.

struts-painted.jpg

 

 

Installation:

 

Step 26. Rub some grease around the tube and slide the threaded sleeve on. The grease will not only help installation, but will provide some corrosion resistance, and thermally connect the strut tube with the lovely heat-dissipating threaded sleeve. Anal-retentive much? Screw on the lower spring perch and put it all the way to the bottom.

step26-sleeveon.jpg

 

Step 27. Install the alu tube spacer and damper, ensuring the spacer is sitting correctly vertical. I was a little worried about the strut being supported at the bottom, so I drilled a couple of holes in the solid alu spacer the same diameter/spacing as the holes in the bottom of the strut; and put some small dowels between the two. Hopefully this will make the strut less likely to wobble around during cornering.

0411091724.jpg

 

Step 28. Using either multigrips (channel-locks?) or the Bilstein part number: E4-MS-08/7 (USD4.93 from Bilstein aftermarket) tighten the gland nut down, checking that between 1 and 2 threads still show when fully tight.

 

Step 29. Install the spring preload bearing onto the lower spring perch. Then cut the lower 4 rings off the dust boot and slide the spring over the damper, being careful not to needlessly bang against the damper piston.

step29b-trim-boot.jpg

 

Step 30. Slide the 10mm spacer, coil-over top, thrust washer, large washer, needle bearing, and remaining washers onto the damper.

step30-installation-order.jpg

step30-washers_bearings.jpg

 

Step 31. Install the strut-top (with the bearing) by screwing the strut top onto the damper thread, and do up the damper top nut. Important: Check that you can hold the strut top, and rotate the coil over top and spring freely. If you have made the 10mm spacer less than 10mm, then the coil over top could be clamping against the damper top and jamming. Guess how I know.

Step 32. Install the whole assembly back into the car.

step32-installed.jpg

Phew.

Hope to be getting EMWHYR0HEN to do the required welding this weekend, but am having second thoughts about reusing the front upper bearing, as it requires drilling out the coil over top to 1" in order to get the top down enough on the shaft to screw it into the stock strut top.

 

But if I get some torrington bearings for the top maybe I can ditch the stock bearing and space the damper shaft out to be snug with the coil over hole.

So I have changed my mind about Step 15, modifying the coil over top. As I plan on eventually upgrading to spherical rod end with camber adjustment for the top I won't be modifying the stock tops. Instead I ordered some Torrington bearings and races so I can remove the stock front bearing, replace it with washers, and hopefully get enough thread through the stock top to hold it all in place properly. At least thats what the mock up showed so I'm hopeful. :)

 

The parts:

 

From Motion Industries: (https://www.motionindustries.com/motion3/jsp/mi/motion.jsp)

- 28mm OD, 15mm ID bearing: 2 x FNT 1528 BRG @ USD3.49 ea

- 28mm OD, 15mm ID thrust washer: 2 x LS1528 @ USD7.62 ea

 

This also means I don't need the 1" drill bit I special ordered.. grrr.. but I think this will be the better solution. All thats left I believe is working out how to get a spacer. It needs to be a piece of tube thats 7/8 OD and 9/16 ID, making it 0.150" wall thickness, aka, impossible to find. I will probably end up trying to borrow a mate's lathe and drill out some 7/8 OD bar myself. I will make a bunch of these just in case other people need the spacers too.

 

Oh and I also got some of these to help with coil turning and adjustment:

 

From performanceshock.com: http://performanceshock.com/index.php?main_page=product_info&cPath=53_34&products_id=542

- 2.5" ID spring preload bearing kit: 4 x tbrg-2.50-kit @ USD22.45

 

Total spent on parts so far: USD844.44

So while my suspension is apart, I figured I'd try to get some adjustable sway bars on the cheap. My plan for this involves modifying the stock sway bars so they can be made both more and less stiff. This is to give myself the opportunity to experiment with a range of suspension setup philosophies. I want to be able to try both ``balance the car with the springs then use a light bar to tune'' and ``balance the car with the bars and run light springs to try and get mechanical grip''.

 

As before, much appreciation to EMWHYR0HEN for his tireless assistance, and for the ride in the beast. :D

 

So.

 

The parts:

 

From Midwest Control: (http://www.midwestcontrol.com)

- Female rod ends: 2 x (don't remember atm, plus they're very small and might not fit - will update later)

- Male rod ends: 2 x (don't remember atm, plus they're very small and might not fit - will update later)

 

From any metal supplier:

- 1/8" hot rolled plate. Around 1.5" x 2'.

 

 

The tools:

 

This assumes a general toolkit with appropriate spanners, sockets, drives and ratchets. Additionally helpful is:

- welder

- angle grinder with cutting and grinding discs

 

 

The procedure:

 

Step 1. Remove the front sway bar and lower control arms from the car. Hang onto the bushed connector between the two for length reference later on. Wire wheel the end of the sway bar to get it ready for welding. Wire wheel the flat while you're at it.

 

Step 2. Mark and cut parallel to the vehicle centre-line on the inside edge of the hole through which the bushed connector fits. This line should be perpendicular to the main sway bar rod that runs across the vehicle when its installed.

step2-mark_and_cut.jpg

 

Step 3. Cut a length of the flat steel around 2" x 4", and tack weld this onto the flat surface provided by the cut you made in Step 2. Optionally, pre-heat the area, focusing on the bar, for welding.

step3-tack_flat_and_preheat.jpg

 

Note: When installed on the car, this flat should extend downwards so be careful that you know which way the sway bar is, so can place the flat appropriately.

 

Step 4. After triple-checking everything is aligned, oriented and otherwise in place correctly, weld the flat onto the sway bar.

step4-weld_flat.jpg

 

Step 5. Get the lower control arm, and wire wheel around the sway bar connector attachment hole. Mark a line on the inside edge of this attachment hole. Grind the raised section down until the plate can sit flat. Weld the flat on both sides to the LCA.

step5-weld_flat_to_arm.jpg

 

Note: On adjustable or lengthened control arms (such as mine), the position of the flat will be different. I used a stock control arm as a reference point and lined the two arms up with the inside pivot points even, then marked (parallel to the pivot axis) over from the stock arm's connector hole to where this was on the longer arm.

 

Step 6. Repeat on the other side of the sway bar and the other control arm.

 

 

I've only done up to here, so will continue the story once I've done the remaining steps which involve trimming the flat plates to the correct sizes, drilling/slotting holes for adjustment, and final installation.

Step 7. Test install the LCA and sway bar to ensure that both plates are roughly in the same plane (beat with a BFH until they are), and are not too far apart. Though the rod ends do allow for misalignment, there is a limit, especially with such small rod ends.

 

Putting the sway bar and LCA approximately as they will sit after installation, mark a line vertically approximately in the centre of the LCA, at the same longitudinal position as the original sway bar mount.

 

Step 8. Remove the LCAs and work out how much flat you want. Trim anything you don't. On an S30 the sway bar has quite a bit of free movement without interference (or so I think at this stage?), so as long as you trim both LCAs the same, you should be ok. Make sure you leave enough flat to drill a hole for the rod end to be bolted.

 

Step 9. Drill a hole in the LCAs' flat appropriately on the marked line, to replicate the factory mounting position. You can then drill as many holes on either side as you can fit. I tried to allow for both more and less roll stiffness, so I have holes in either side.

step9-drill_holes_in_lca.jpg

 

Step 10. Cleanup the flat, and hit it with the spray can.

 

Step 11. Remove the sway bar and repeat steps 8-10 for the sway bar flats.

 

Step 12. Install the sway bar and LCA. Bolt one rod end into the holes replicating the stock sway bar position to start with. If nothing else, this will verify that the tiny rod ends are strong enough to not get ripped apart. When bolting into the other side, adjust the rod end as necessary to ensure the sway bar is not preloaded. I.e. don't heave down on the sway bar to get the bolt holes to line up.

Just bought some bits for the front brakes from ruggedbert (good bloke).

 

280-brakes1.jpg

280-brakes2.jpg

 

Wilwood Integra-4 GT calipers: Used but appear to be in good condition, missing a bleed nipple on one but not a biggy. JSK hats, and Wilwood 12.19" (~310mm) vented rotors.

 

I also have JSK rear rotor hats. So quite a few things left to buy, but getting there. Still need:

 

Braided lines on all corners

Rear discs

Rear calipers - will probably go some small wilwoods to keep it all in the family.

Pads at all corners - most likely Ferodo DS2500 unless they're stupid expensive over here.

 

Trying to find time to finish the coil overs and suspension. I hope getting the rear control arms will be the stimulus required. :)

Made a little bit of progress on getting it all back together yesterday.

 

I pulled out the old 3.54 diff, and cleaned up the cover and all the rear sub-frame for installing the 4.11. I painted the rear subframe black, but left the rear diff cover bare alu.

 

I also got the local auto shop with a hydraulic press to push the pin out of one of the rear strut stub axles, and then dropped off the strut for the other side to them as that one doesn't want to budge either. So I assembled the coil over for the one that I got back.

 

Here is the left rear coil-over installed.

0411091845.jpg

 

And here (not really visible) is the cleaned up rear subframe including new bushes in the moustache bar.

0411091847.jpg

 

So all that remains is the final coil-over, bolting the cover onto the 4.11 diff when I get a new gasket for it, reinstalling it, and then bolting up the rear lower control arms. Oh and greasing the front tie rod ends and ball joints, and an alignment (and perhaps corner balancing). :)

 

Hopefully not too far away.

Ok, the car is back on the ground after some suspension work and tie rod ends. Its been off the road for a long long time, so long that the engine is now very unhappy about life. It'll sputter along running on buggerall cylinders for as long as you can be bothered holding your foot down around 20% throttle. If you stab the throttle it dies, if you take your foot off it does. And there is a decent amount of blue smoke coming off the engine bay. I'm not sure if its the oil/grease from me touching stuff burning off, or if there is somehow a hideous problem and its ingesting massive amounts of oil? It started like it'd never been stopped, but then quickly developed this problem a few seconds later. Very sad.

 

Anywhere, here are some pictures of how it sits now:

Fixed the spluttering issue: http://forums.hybridz.org/showthread.php?t=155881

Took it for a spin last night just to smoke test it.

 

Some pics:

Wheels didn't fall off, but the clutch slave is jamming over extended. Will order a new slave and replace it this weekend. :)

 

So good to be driving it again. Locked diff is familiar, though the 4.11 gears aren't anywhere near as revvy as I was expecting. Guess thats a good thing. Stock L28E is still slow as sh!t.

Been a while since my last update.

 

Since the above pic the car has been driven a few times around some fun roads, served daily duty for a month or so, then went to vacation at my grandmother-in-law's place where it has a garage space.

 

I've also given up trying to keep this a road-car project, and am more or less resigned to using it as an extra large mechano-set. Ie, something I play with to get a feeling of building things.

 

So, to that end, I purchased FG doors from Reaction Research, and now the car looks like this:

CIMG0362.jpg

No more progress on this front unfortunately, though I did get a set of 280z door latches to put into the doors so they'll close again. Current plan is to run lexan windows fixed in place with a horizontal slidey window, through which one can reach to open them. Hopefully that'll pass scrutineering? Will confirm before I do it obviously. :)

 

Also will be purchasing carbon bonnet, hatch and roof skins from Reaction Research soon as I can afford them.

 

 

In between all this not driving the car, started talking more with my mate in NZ who road races a RB30ET VL Turbo, he convinced me in the land of the V8, I'd be crazy not to go a VK56DE. Hence after hesistant searching, and thanks to my russian connection:

CIMG0377.jpg

 

Engine sitting on my shed floor:

CIMG0378.jpg

CIMG0380.jpg

CIMG0381.jpg

 

From a 2007, non-flex fuel Nissan Titan you see behind the lovely two chaps in the first pic. Advertised as only having 7000mi on it, which I'm a little dubious of, but it is extremely clean, as was the entire underside, save some dirt splashed on the sump.

 

So thats where things stand. Immediate jobs:

 

1. Get the FG doors painted and installed.

2. Plan the intake manifold for the VK. Hoping to be able to adapt some cheap motorbike throttle bodies.

3. Collect more parts for the conversion: aftermarket computer, fuel pump, injectors, fuel line etc. Remote oil filter kit.

4. Normal conversion crap: trial fit, measure, repeat.

So just to keep this thread updated.

 

Found this pic 12409Buggy001.jpg from Kurt who built an awesome VK56-powered buggy. Coupled with this post:

 

Getting Motor ready to fit into Buggy Chassis... I am ditching the 2 qt factory oil sump and adding a 2.5 qt dual filter remote system by Amsoil. I am also adding a Moroso 3qt Accusump for even more Motor protection. This will allow me to place the Motor 4" lower in the chassis ! Motor should be fitted to chassis within two weeks... Will include photos then as well.

VK56MysteryCavesLizard001.jpg

 

Makes me think that Kurt is awesome. I'm trying to get in touch with Kurt to see if I can come have a look at his setup' date=' and/or convince him to replicate it for me.

 

If the engine can go down 4" the stock intake may well clear the bonnet, and enable me to get the car running without fronting the cost of a new intake. I very roughly measured the intake port spacing, then felt like a fool as you'd expect it to be relatively close the bore spacing, which I believe is 92+8.8mm. I doubt any motorbike has 100mm port spacing, given they typically run much smaller bores, so need to keep investigating other options. Might be a cheaper way to get the extrudabody ITB setup if I do bits of it myself, though its $1080 just for the raw ITBs, with no linkages, mounts, horns or filters. :(

 

Got in touch with JWT for cams for the VK56 with VCT, they say that the intake cams are limited in the duration/lift they can run without piston recesses due to the relative movement of the intake cam. Asked them how big you can go until you reach that point. Waiting for a response.

 

About to go email Autronic and ask them about running a VK56DE with VCT, and if they have any suggestions. Again, Kurt's invaluable pic: [img']http://i296.photobucket.com/albums/mm178/kscherbaum/VKCamsetc001.jpg[/img] provides a hint as to what the timing input from the stock VK56 looks like. Remains to be seen whether the Autronic will work with this signal. Also remains to be seen how you splice together the two different signals from the two intake cams? I'm definitely not used to working on an engine with more than one cam. :(

Another example of DIY ITBs using Hayabusa throttle bodies. Note these have been spaced out, though I wish the pics were higher resolution so I could see how they altered the throttle linkage mechanism to work with more space between them. Maybe it'll become more obvious once I get my hands on a set.

 

Also trying to find out the mods required to fit larger bosch injectors to the hayabusa ITBs, but again, likely will be far simpler once such things are in my hands. Urgh, forgot how expensive fuel systems are.

 

Have also been in touch with Kurt, who was very forthcoming with the mods to the sump above. Pretty complicated for a fabrication-n00b like myself, am likely going to ask Kurt nicely to modify my sump the same way he did.

 

Was in touch with JWT re the cams, though no definitive information about the largest cam the 2007+ engines will run. Ideally I'll be able to just take it down there and try them, but thats a bit presumptuous now isn't it? ;)

 

So the plan for next month is to tell the stock parts I don't need: injectors, intake manifold, TB, exhaust manifolds, power steering pump, and try to use that money to get a couple of sets of Hayabusa ITBs, and some alu plate to start mocking up the intake manifold. Apparently the stock Hayabusa velocity stacks are relatively cheap, so will investigate them more.

Sold the intake. Still trying to sell the injectors, the throttle body, power steering pump and the exhaust manifolds/headers. Lemme know if you know of anyone who wants one.

 

Just bought these: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=380248878526&ssPageName=ADME:X:RTQ:MOTORS:1123#ht_3008wt_941

 

(2002 hayabusa ITBs).

 

Still looking for a second set.

 

Starting to research how to go about getting adapter places machined up to go from the intake flange pattern to a weldable section for the TB.

 

Then gotta find someone to machine up 8 of them. :)

 

Contacted nizpro marine in my home city of Melbourne. Their vrz-60 engine I believe is based on a VK56DE, and makes 1500hp and spins to 8400. Guessing they have a little experience with these engines and might be able to advise/supply regarding camshafts.

tight little stock exhaust manifold. Reckon a set of headers should get things flowing a bit better. Hopefully gunna go with a front guard exit, though depends on clearance I won't know til it's in the car. :)
