Achievement unlocked: not crappy rims on all 4 corners




Tight fitment, just the way I like it;








Before anyone asks me questions, The rears are 17x10 +18 with a 1.5in spacer (effectively -20). the fronts are 17x9 +22 with a 1.75in spacer and a 7mm slip on spacer (effectively -20) And I could probably do away with the extra 7 mm spacer.


Tires are Hankook RS-3's, 235/45/17 in the front and 255/40/17 in the rear.

It feels super planted now, compared to the steelies I had with some all seasons. These rims saved me about 5lbs per corner on weight (wheel/tire combo is 10lbs lighter per corner, but the spacers add 5lbs per corner).


I'm actually thinking of heading to discount tire and asking how much I can get back if I trade in these hankooks and go with something stickier.

I got it for $40. I went to the guys house to buy something else like a fender or something and the asked if I was looking for anything else, I said the only thing I'm looking for is a wing and Tada he had it hidden in the rafters. Asked him how much and since I was already buying other stuff he threw it in for $40 more. What a steal.


Edit: just remembered it was a wiperless hatch I was getting, the original on the car had rust issues and this guy had a hatch for $100

So it begins. Pulled the SR20 out of my parts car this weekend and stripped out almost everything else I need except the windshield. I bought this car pretty much just for the engine, saw the add and checked it out. It did run and idled fine, but he couldn't rev it past 3k, probably a fuel problem since the car had been sitting for like 5 months he said. On top of that the headgasket had been blown. Bought it for $2400 and to date I have sold about $1100 of parts from it so far with quite a few parts still left, I could probably get another $300 easy out of some parts, just need to get the shell out of my garage. $1300 isn't bad for a running, modded, 300whp sr20 even if it does have a blown hg.






The engine hoist was bleeding oil and wouldn't lift all the way, so I ended up cutting the front support off





Finally got it out and separated the tranny (came with a B&M short shifter = win)





It has an aftermarket spec clutch and some aftermarket flywheel (unknown if lightweight or not) which I will probably be getting rid of. Tranny has the short shifter, engine has rocker arm stoppers, came with a freddy intake and tomei tubular ex. headers, isis downpipe and it has a more than likely blown GT2871 on it. Will be scrapping the shell this week once my weather strip comes in and I can swap the windshield out to my s13. 


Basic plans are to completely rebuild it, eagle rods and wisco pistons, new clutch and flywheel, keeping the freddy intake and tomei exhaust and isis downpipe. I'm going to be replacing the turbo with a similar one that was rebuilt by my friend, but has a journal bearing center along with buying my friends side feed 550cc injectors. I'll be ditching the tuned ecu in favor of a haltech standalone complete with a full set of custom guages (not sure if I want speedhut or autometer yet). Since the dash will have to come out at some point I will be removing my AC core and some of my ducting since I only need it to defrost my windshield really (and because my heater has been stuck like that since I bought the car). There will be a lot of fab work, which I will be doing under my friend Brian's careful guidance, along with putting the engine back together. 


End goal: 400whp tuned on pump gas, along with the ability to say I put it together all by myself

Well this weekend I decided to throw on my stock turbo stuff just to see how it'll feel. It was one of those "I've had the parts forever and if I didn't at least try to use them I'd never know".


Started with this, a nice healthy NA L28 that've I've put about 35k on since the rebuild, including several cross country trips. Runs fine, but is definitely starting to show wear and tear and some leaks. 



Had this on my shelf. I bought all these parts a little more than a year ago intending them to go on in summer. Well I got lazy and they I studied abroad in Europe last fall and spent a lot of money.



Removal is the first step: took me about 1.5 hours to move the car into the garage, jack it up and remove the manifolds and entire exhaust. Not bad. Took it around the block once with just open headers and I'm pretty sure I pissed off my neighbors.



Nice, clean, coated turbo mani, but I wanted more heat protection since I live in FL




First mock up for a little motivation:



Test fitting the N42 intake. As you all should know the PCV valve on the bottom of this intake is in the way of the turbo/jpipe coupling. So I did what a few memebrs here have done and fit a 90* bend and ran the PCV valve inline. Came out pretty good..




Then the most time consuming part, swapping the oil pan out. Literally took me about 4 hours to do including an hour to get the motor back in place. First step was to jack it up to get clearance. At the time I thought it would be a good idea to just unbolt the mount from the crossmember. Well this turned out to be impossible to get both the bolts back in properly and I gave up and unbolted one of the rubber insulators and set it back. 



Healthy looking engine.



Healthy application of hi temp silicone to hopefully beat the leaks. The old gasket on the NA oilpan had cracked and was letting oil through towards the front timing cover:




Final mockup:




at this point I was tired and just shoved the AFM to turbo boot on and wedged it between the front swaybar and rad, I just wanted to start the engine. Topped the oil off, connected the few electrical components and the fuel lines. One thing I didn't show if the turbo injectors on the manifold. I had them sent to RC engineering and cleaned, which turned out good since one of them was only pushing like 180cc/min. After the cleaning they were all right at 270 though. 


Basically I had gotten everything prepped, I took the Jpipe, oil pan and manifold to get sandblasted and painted and the headers coated. I had the injectors clean and had all the gaskets ready. There wasn't much else I could prep without actually taking parts off the car. There are still a few things to be worked out, like the AFM boot. But the biggest thing I have to fix right now is the Jpipe to TB gasket. my Jpipe didn't come with one, so there is a massive gap and air leaks into the TB. Somehow the engine managed to idle at around 600rpm after some coaxing though. 



In the end this happened:


I had to crank this thing like 15 times before it started because the oil pressure needed to build up and the fuel pressure had to build. My roommate was there watching with a fire extinguisher ready and when it started I just started yelling. It was a fantastic moment. As of now I'm using the NA ecu, dizzy and harness. Things I swapped in are the turbo injectors, oil pan and of course the turbo manifold, turbo and downpipe. This is a temporary setup which will last me about 3 months hopefully. Stock boost levels and hopefully nothing explodes.

Well messed with it today to actually properly sit the AFM and also found a piece of rubber I could cut down to fit around the throttle body for the Jpipe. First I cut out the bracket that hold the NA maf, Then sanded and painted over and it fits like a glove now. No vibration since the stock rubber boots absorb all of it. 






Don't know if you can tell, but in the last pic the afm is backwards. After I put it together it would idle, but just wouldn't rev up. As soon as I gassed it it would die. I spent about 2 hours trouble shooting, checking connections and adjusting the timing and idle. Finally when I was about to swap out my afm for my old one I noticed that mine was backwards. D'oh.


Well it runs now, stumbles a bit and I attribute that to the lack of fuelling going on under boost. Next couple of steps are to get a boost gauge and wideband A/F gauge. I'll be ordering those tomorrow, as well as getting my exhaust attached. Gonna stick with 2.5" since it's what I have. pics will come once my exhaust is back on, along with a video. 


I have to say though, it sounds pretty mean with just the downpipe on.

Few updates, First off got the downpipe made. Nothing that the muffler shop had fit, so they ended up slotting a regular 3" 3 bolt flange. It goes from 3" and reduces to 2.5" to match my exhaust system.





On top of that I did some heat protection. 



Also put a few strips on the underside of the intake and the runners, and around the PCV line. I just did a really bad job so I didn't take a picture.


Lastly I finally got my STI diff in. The axles came sometime last week, rand to the hardware store to get some bolts to put them together, and just let it sit there as I did the Turbo swap. after that I took a trip to Miami so I couldn't really do anything this weekend. So today I got out of class early and told myself I got this. Took me about 1 hour to drop the 4.11 in there with the axles, spent about 30min cleaning up the new one and swapping covers (the STI cover had a temp sensor in place of the fill up hole and was missing studs). Filler her up and spent about 1 hour putting it back in. All in all the job with breaks took about 3 and a half hours. 


Here you can sorta see the clutch packs. Its from an 05 STI so its a CLSD.



Both of them side by side



Adequate use of RTV to seal it.



Finally installed



The difference is insane. This car now hugs corners with ease, no more skipping. I only drove it for about 5 miles to make sure there were no clunking sounds and to make sure nothing was loose. If you're thinking about getting an LSD, do it. Aside from sticky tires this is the most notable handling difference I've felt.

Yeah. When I had the engine rebuilt for my 280zx 2+2 I bought a Turbo oil pump. Difference was very noticeable. The oil pressure always around 3/4 of the gauge. You could probably get away with the NA oil pump, but why bother, you probably have a worn out high mileage na pump anyway.

Do you remember if you got the oil pump for a manual or automatic transmission?

Been busy with school and gathering parts:





Also get distracted by my S13 sometimes. I've actually gathered parts for a full z32 brake/5 lug swap. Finally got everything I need for it, just need to get the stuff cleaned and powdercoated. I actually just picked up some rims for it with used Proxes RA1's, but since I'm still waiting I'm thinking about burning up the rubber on the ZX:

do you have their number? or website? i'd really like some in the same size and spacing as yours. also did they vibrate too much i heard that this can also be a problem thanx

btw is there any chance you happen to have your set laying around and wanting to get rid of it? if so PM me thanx

I sold my wheels back in February, apparently their website is also down. It should be diamondracingwheels.com


This should be there number: http://www.yellowpages.com/milwaukee-wi/mip/diamond-racing-wheels-inc-1784920


I had absolutely no issues at all with them. They balanced out fine and never wobbled or vibrated at speed. There have been cases where this did happen though, I guess I just got lucky.

Stuff has been moving slow, The machine shop told me one of the head studs was JB welded inplace so the block was fubar. Found another locally for $50 off zilvia and dropped that off last week. Still no word on it. 


Recently did a 5lug/z32 brake conversion on my s13 daily. It's a lot more fun now. I've also gathered all the parts needed for the 5 speed swap so that will be happening sometime soon. Also sold my CBR to fund the engine build.
