When we were working out of the shop in Santa Ana, the Precision Powdercoating Olds DCRE engine spares were under the shop tables we were using to work on... and the spare tube chassis was slung into the rafters.
It was always "Hey Monty, what you going to do with these bullets? Let's put one in one of my Z's and go to Bonneville..."
For the price... I'd put it under the bench, eventually you will find something to use it in... Maybe a Hillman Imp or something interesting that is just so wrong it makes sense to do it! That is what that kind of engine is destined to be great in!

Why would you need two manifolds on opposite sides of the head? A manifold with equalization runners to make up for differences in the in-head portion of the port would allow this design to function without double manifolds.
Kind of like the 'inline V-6' VW makes now...

Mid corners... don't even get me started on boost threshold coming in halfway through a corner and loosing traction. It was the reason for the whale tail being added to my 240Z...
-
That's what I got with triple mikuinis boosting to 350rwhp in daily driving 22 mile one-way through Carbon Canyon to work from corona to brea every day...plus some weekend running around and club events.
Same basic setup as Gumbys.

pull teh cam cover, get the dial indicator and degree wheel out, and do it right. You can't tell anything timing wise from the position of the lobes other than the thing is within maybe 90 degrees of being correct...
It's what? 8 bolts....c'mon! Sticky on it as well...

Frank280ZX found several 280ZX's in my yard like that when he came the first time... He was amazed by the lack of rust, and ended up picking through all the piles.
Really, there's no need to make them that small unless you are putting them in the recycling bin out front of the house for trash pickup and don't want to draw attention to yourself.
I cut to the size that is easily tossable with one hand, and then go searching for unlocked dumpsters if it's something I don't want to bother taking to the scrapyard...
But when the trailer is piled high...hey, that's $50!

Anybody remember the Buddy Hackett routine about him out in the boat fishing and thinking...
"FF! FF! FF!"

I am assuming sarcasm there^, so yeah strokers are slooooow and dull, bahaha yeah ok, tell that to this guy!
You assume correctly, you've seen the posts, all the blah blah blah about the slow and low revving strokers... For guys that have built cars like that, you just gotta shake your head when you hear the internet parrots squawk.
I've actually bookmarked that link for use the next time someone makes that contention at 'another site' where the parrots fly freely and make droppings on a regular basis.
It's going to be good to post someone else's engine for a change...
-
It's pretty obvious, he states it clearly: the engine is below 50 CID. This is right in the CVC, they are exempt. Your engine is something like 168CID, you won't qualify.
Now, I got to figure out how to get that guy to hold on to that jeep till I get back and buy it. I had an 80 exactly like that one but with a 550cc two stroker. I could not kill it, and it would climb trees, this is EXACTLY what I need for my back yard, and to double up behind the Z i nthe trailer when I go to El Mirage! I want that truck.
Funny thing is he's asking $800 more than I paid for mine in 1984, and mine had less than 10,000 KM on it then! Sold it in 89 with almost 80K on it!
-
As for N/A L-series, i found this guy in Japan that runs flat 11s in street trim!
Now remember when viewing that: Strokers won't rev. Strokers are slow to rev. There is a crank harmonic...
-
Well I know when Frank was driving Jeff's car he was making it through 3 gears to a 7000 rpm redline in a set distance of about 1/4 mile, and back to a slow enough speed to make the corner... 0-90-0 in less than 1/4 mile.
I wouldn't exactly make the offhanded remark of 'dyno queen numbers' with that kind of performance on tap. It's rather insulting, IMO.

It doesn't supply vacuum, it supplies fresh filtered and metered air and acts as a bypass around the throttle body for idle speed control.
Put a bung in your piping coming back from the intercooler, and you will have the same thing you got now for functionality.
The constant source for Manifold Vacuum to the AAC will work fine, if you have a later model AAC, with the little setscrew in it, you can just screw that screw in till the bypass allows the idle speed you want, and you don't even need to connect vacuum to it at all, it will act as a fixed idle bypass just like on EuroTurbo cars.
Realiztically, all you need for idle is a 1/4 line, that is more than enough. I took a hose barb from one of the turbo scroll connections for the wastegate (my wastegate is hooked up to the plenum...) and ran 1/4" hose from there to a modified N/A idle air bypass screw thingamajig, and then plumbed it with a 1/4" hose to the manifold as a premanent bypass (like the Eurospec Turbo cars had...no AAC for them!) It will suppy enough air for anywhere from 300 to 2200 rpms. With a 1/4" barb hooked up like that, none of your pipes will need to have anything put into it. But it needs to have that boost reference, because if you hook it to the boot between the AFM and the turbo inlet....when you go on boost, it will leak through whatever metering device you are using (AAC, fixed idle bypass thingamajig) and blow boost into that same area. This is why it's on the J-Pipe to begin with.
Hope that makes sense. I have photos of some of it on the 260ZT page at cardomain of sharkie73z...

Hey, facts are facts, when I assisted my friend do his "94 in a 74" LT swap with his Camaro and saw tunercat in action (since I had to teach him how to use it, HAVING NEVER WORKED ON IT BEFORE !)....
For the price of the LT's now complete as drivetrains or hell even whole cars... it makes rationalization of expensive swaps really hard, if expense is considered. Why spend $4500 for something that is totally stressed and makes an honest 280-300, when you can spend the same and get 330 in stock form (or thereabouts?)
Same goes for M-Sport crap in Europe. It's laying about everywhere. You can't even trade it for a loaf of bread. It's like rat turds, they brush them into the canals to get rid of them...
When they proliferate like that, and get so cheap, it's hard to love on the OEM stuff. I mean, if I was going to do up a ZX.........
-
Didn't they have their sleeve/block top extender for the RB315 on display?
I would think a kit that bunmps the RB26DETT to 3,138cc's would be of more current interest to the clintelle here than a whiz-bang edition to an SOHC design that has proven it's worth to well over 700HP... I mean, where's the 1200HP OS Giken Engine Dyno Slip? We all know the Electramotive Car was running around with 800-1000HP depending on boost levels back in the early 80's running primitive turbo and EFI/Spark control... OS seems to have stayed in it for development, they have to show me the worth of the modification, becasue the headwork to get an L Series to that kind of power level is well shy of a small precentage of the cost of that TC24B1 head alone...

Says the man with the LN2 Dewar at work...

Try to go someplace that sells it in 'pellet form' it's a lot easier to spread, and gives a much more uniform dispersion than a block of it broken up by hand. They look like little fish-food pellets, up to the size of packing styrofoam pellets. The smaller the better. Broadcast it on and let it go for a while. Just do it with the garage door open, it will displace oxygen, and you will start breathing really fast if it's deficient... you will just pass out if the O2 displaced in the cavity was less than about 15%. (Meaning, don't throw it on the floorboards then close the doors with the windows up, coming back to that and opening the door can cause you to pass out with one full breath and fall onto the floor in the car...making things much bleaker for your survival!) Ventilate well.

Hey, what's not to love? M5 making 345HP, with the ability to twist to 7200 rpms?
Engine, Controls, and Six Speed Manual Transmission for under 2500 Euros?
Considering what someone in Europe would pay for "Exotic Japanese Speed Parts" I'm thinking, yeah, that's WAY cheaper! I think Frank mentioned he got his for 1500 Euros. They're everywhere there. Hell, the guy is driving around in an Armored 5 Series Wagon they're so cheap!
ARMORED!
And from what I hear, on the Autobahn, that 2-Tonne Panzerwagen will WALK a Eurospec 350Z at 160kph and never need to look back!

Probably gas weld over the RHD VIN and surface condition it... it will look like it was never there unless they x-ray it.

TOO COOL!
Tony: Do you tow the Harbor Freight trailer behind an s30?? Got a link?
Look around for photos of the San Antonio Convention in...2004? I took it there loaded with three Rubbermaid tubs. Went 18,000 miles in 3 weeks with that thing behind me.
I got the idea from all the SCCA guys here in SoCal that had a truck tool box on the front half, and their racing slicks chained to the back of the trailer with no decking on it, works great like that. When I built mine, it has all sorts of options to take the deck off, or screw things down to the deck. I can hold a 48Qt Cooler on a boxed frame I put on the tongue, and I carry two spare wheels underneath the deck, as well as some hardened chain and watersealed locks... when I get to a hotel, I chain it to a lamp post through the spoked wheels and it ain't going nowhere with the tongue lock on it! Way too much effort. Hell, I spent more for the aluminum diamond plating on the deck and weight-capable tie downs than I did on the damn trailer!
I got some photos, but nothing online that I know of... I got a nice one of it in front of the Mackinac Bridge (yeah, you wouldn't think it was on the way back to SoCal from San Antonio, but neither was the Smoky Mountian Parkway, either (see how that 18K rolled up?)
It's a great tower behind an S30. My only caveat would be to not run an R180 with a 3.90 gear and take it through the southwestern desert at 85mph for 14 hours+ at a stretch...unless you got a diffy cooler. If you plan on towing in an S30, do it with an R200.

Re: Post #13
Roosty, it looks like you are about to make a very vulgar tongue gesture in that photo... blawalalawalalalawal!

"I want torque but still be able to pull it to 6000rpm on steep hills in low range."
Ain't Happenin'...
Might I suggest a BMW M-5 V8 better suits your needs. Discuss with Frank Poll in Utrecht, he knows the tricks mounting that powertrain where an L28 once sat...
Cheaper than the stroker from what I understand as well...

Magnetic Chuck in Surface Grinder makes short work of the lash pads...

Like Oz mentioned a radical adjustment by 'accident' of one tooth slipped on the big cam gear (what is that, something like 9 degrees) really changed the engine's manners. It had a bunch of torque in the lower rpm ranges, but was absolutely flat at 5500 rpms. As in you really didn't want to even run it past that point as it felt as if you were actually slowing down (like a governed go-kart doing downhill!)
But from the stoplights and around town it was a really torquey change, and that was a stock cam.
The Racer Brown articles go over what does what on a camshaft, it's not duration you are looking for, but altered timing events and if anything more lift. Stock cams generate pretty good down low torque, but by altereing the valve events earlier you may pick up some more low end at the obviousl sacrifice of higher rpm performance. In a Patrol, likely that is acceptable.
Probably in a 280ZX as well... ;^P
Double Cross Flow Cylinder Head

OK, I'll just come out an SAY IT: the reason I mentioned VW's "Inline V" was because you would be able to make a 15 degree V12 that LOOKED like an inline six, and had the unequal length runners and all the complexities inherent in a design similar to that originally proposed. Save that at least then you will have 12 cylinders in the space of six...
If you're going to make things complex, get something out of it! Like double the cylinders in the same longitudinal space...and not much more width-wise (not much more wider than a DOHC Head...)
