So recent additions include, mostly trying to make the car more reliable for track days. especially the ones 700 miles away.
-Putting stock manifold back on (more power, won't crack) not that the ebay one did. at least 8 or so track days on that ebay manifold. again reliability.
-duct work for cooling, putting stock undertray back on, sard cooler t-stat. made huge differences in cooling on track and DD.
-making the turbo stay on the manifold. lesson learned those clips do do something.

got a new gasket for outlet, probably just didn't notice with previous gaskets but the one hole on the 2871r is way off. still works, just puts a bit of stress on the gasket. and new bolts which can make tightening them easier if they get loose.

new nissan gasket for inlet, new clips to keep the nuts on. don't throw them away, they do do something.

Heat wrap aroung the area where the coupler connects to the turbo. used to always pop off there from the heat. only had a couple feet couldn't do the whole manifold. ceramic coating would be nice but taking the turbo off sucks and i want to drive it. this works just fine. stock heat shield might work but i don't have one.

The cooling panels just made to fit in between the intercooler and radiator, directing all the air so i has to go through the radiator. with a bad t-stat i was seeing temps down to 150 on the way home from TH. and for that last Thunder Hill track day it was easy 95 outside and temps stayed around 200-210 on the output pipe. still can do some more to block air passing around the radiator but this was a big improvement.

I've had my luck with T-stats so i always test them before i install it. sard on the left, stock on right. i ordered nismo stat from phase 2 but they were on back order so they sent me this one. was kinda scared but it tested fine and works much better than this stock one which seemed to be sticking open. 2nd pic is pretty bad but the sard one is open and the stock one is closed at i think temp was 190.

Next up rear wheel bearings maybe a front one too.

no but man was it easy, i can bring you a piece i started with.

e1_griego · 08-14-2008, 12:48 PM

That would be rad

. Are those just riveted on? I had the bumper off but wasn't sure how to attach any pieces.

Your_Mom · 08-14-2008, 12:57 PM

i made it pretty tight fit and just used one self tapping screw per side.

e1_griego · 08-14-2008, 12:58 PM

Ah, ok. That make sense.

JLightning · 08-14-2008, 01:42 PM

just out of curiousity, if the stock manifold makes more power and is less likely to crack, why did you ever have the ebay one on in the first place?

Your_Mom · 08-14-2008, 03:33 PM

i didn't know it i'd loose that much power, looks better, and i thought it might help my coupler popping off issue. i didn't care if it cracked, i could just weld it. but now i'm doing track days outside of PIR. so that changes the whole problem if it does crack while out of state. other than that i can't remember if there was a better reason. maybe just stupidity or ignorance. but it did help the coupler issue.

Your_Mom · 03-06-2009, 08:09 AM

Richard stopped over yesterday with some new goodies.

Out with these old housings

In with the new and since i don't have baller rims, i figured i have baller coils so had to throw up the cellphone.

New 2871r .64, new IC, B&M shifter, and a serial gauge for the aem. all need to go on, very soon.

UP Garage · 03-06-2009, 08:27 AM

Brian:

What is the compressor inducer diameter on your 2871?

Douglas

Your_Mom · 03-06-2009, 08:30 AM

damn it doug why you gotta use big words and shit.

I don't think i can fit a micrometer in there to find out.

UP Garage · 03-06-2009, 08:39 AM

What is the part number? I can look it up.

The reason I ask is I had an epiphany the other day. Garrett has many part numbers for the 2871. I attributed this to the different housing configurations but not only are there different housings styles but there are 3 different compressors that are available.

All this time I have been using the smallest compressor and trying to get the same HP that others are getting with the largest one.

Yes, I am a slow learner for sure.

Slideways74 · 03-07-2009, 09:46 PM

How much power are you getting out of the smaller housing? Im gonna use this turbo on my coupe as well, so just lookin to see what I can expect.

Great looking car by the way. I sent you a PM about your wheel size and offset a long time ago, and now that I see this post I see why you didnt respond.

Your_Mom · 08-03-2009, 03:08 PM

updates from long ago.

Dyno after new .64 turbo. the difference you see is .86 2871 with ebay manifold and .64 2871r and stock manifold. 200 ft lbs by 3500rpm.

1st track day of the year was at ORP on the 18th with ORPCA.

Jack the car up a couple days later and worked on something, let the car down and backed out of the driveway, tire rubbed something. jacked it back up and found.

Got new upgrades from SPL.

Had water temp issues on last track day, so started doing some better duct work. also got rid of the 12" flex a lite fans and got a stock clutch fan with shroud. electric fans are stupid. stock clutch fan is the only way to go. don't be retarded keep you clutch fan. thenismoshop.com had the shroud for 30 brand new.
The duct work
made a out of cardboard 1st

then aluminum

Luckily the left side copied almost perfect to the otherside

Then made a piece that goes from the IC to the underside of the front bumper. and got the pass headlight in.

Made my own cooling plate that connects to the gtr grill

nice and tight

Your_Mom · 08-03-2009, 03:31 PM

And did another track day with Palatov motorsports at ORP.

Then my wife got some used V710's for my birthday. at the same time we found some 17x8 rpf1's with 225 hoosier slicks. and then had my 1st track day with slicks at ORP.

with slicks on 17x8 +35

Your_Mom · 08-15-2009, 02:38 PM

Went to PIR yesterday and a friend got me at 1:29 with v710s on. not bad. there was a z06 with full hoosiers on and was just horrible, he wouldn't let me past him. that and in the straits he just pulled on me. Only got passed by a badass E30 M3 driven by a guy that lives at PIR.

But the 2nd session they said i had a good bit of smoke out the back, the dip stick popped up and threw oil everywhere. being in denial i got a piece of metal wire and held the dip stick down. 3rd session was fine no issues, at the end of the 4th, i've filled up the catch can and covered the engine bay with oil. Not only that but since i evacuated so much oil, i watch my video of the 4th session and on the hard left turn my oil gauge was beeping (for low pressure), but i couldn't hear it with the helmet and being on the gas. stupid me should have added oil but didn't. Oh and when i hit the peak button on the defi thing the oil pressure peaks above 140psi. that maybe a fluke but i don't think so.

Got it home just fine, car runs just fine. compression is 155, 160, 155, 160. Plugs look great. Aem shows a peak of .5v of knock, which to me is minimal. but the last time at ORP i had to turn down the iginition cause i was getting some 1v+ of knock. So i really don't doubt the rings are bad, but could it be something else, the turbo is fairly new, valve seals were replaced when the motor was rebuilt? Nope i'm f'd.
