Well, after a rebuild with some TTZ pistons, the project finally came together the other day. Pics can be seen here http://www.cardomain.com/id/madmax024.

I did this setup a lot differently than most that have gone turbo (3rd, 4th, 5th). I decided to make my own y-pipe kinda like the 4th gen vq30det. I am sure its different than the 4th gen one, but for those who know what i am talking about, its kinda like that (not sure if the pics give it any justice). As for mods I have

370's
Z maf
24*6*3 dual pass intercooler
tial 38mm wastegate (5lb spring)
t3/t04e (60trim) A/R:.63(stage III)/.60
3" downpipe
S-afc II

For now I am running just the 5psi spring until i get some colder plugs. Thing runs like a bad mama jamma except for the fact that the ecu is still acting like the knock sensor is bad. The ecu doesnt throw any codes when i do a diagnostic, but the car is still horribly slow and wont boost until after 3500. But when it does, its awesome. After i get the knock sensor problem fixed, get some new plugs, and a boost controller, I will hit up the dyno.

The entire kit (lack of a better word) was fabricated by myself. I know that there have been some requests for a 3rd gen (VE) turbo kit. I would be willing to make some for members if there were some serious inquiries. The kit would come with a y-pipe setup like the 4th gens do though. The y-pipe I made took a long time to make. The kit would come with everything i have on my car except for the injectors, a Rising rate FPR would be substituted. I can price it out if any one is interested.

 

Nice! Stock ecu? Must run rich on the 370s and Z maf? Looks great!

 

looks great

i assume you have the stock ecu but correct me otherwize

any startup problems with the 370's/z maf/stock ecu

are you haveing any problems with the z maf on the non charge side

are your exhaust manifolds modifyed or custom i cant really tell for sure from the pics

any problems with your intercooler scraping the ground it seams kinda low

 

looks real good. nice job!

 

Nice job, turbo VE's are phat. If you don't mind me asking, how much did the whole setup cost you, and how much would you make a "kit" for?

 

looks sweet!!! that intercooler pic is crazy

 

I'm "seriously" interested in a kit if you decide to fab one.

In general how much did everything cost you?

 

You should put a catch can on your downpipe so you can reuse half the gas


fap fap fap

 

oh yeah, you should email John a link

 

why does RI seem to have the majority of boosted 3rd gens??

 

Any under car pics of the pipe work?

And did you just do a regular rebuild aside from the ttz pistons?

 

VE rods
EGR block plate
dont think he has MaDMaX024's spacers
VTC's rebuilt

Dont think there was anything too special about it. I heard it was sluggish without boost (because of the 8.5:1)
I gotta stop knowing crap about other people's cars
because they have nothing better to do?

 

You can see sorta what he did with the front manifold and you can see where the turbo is. So there's not much choice but to bring the front/rear exhaust across and forward to the turbine inlet. When he says "new Y" that more than likely means a reverse Y that has the collector forward and then up to the turbo. He has the compressor outlet pointed down and you can see how the IC is configured. So the compressor outlet just goes right into the IC, then out the same side then into the TB.
One think I noticed is the turbo looks to be upside down.

 

......

 

ahh, it looks like you've been busy. I sent you a PM earlier...

Looks good, I can't wait to see the dyno results and track results when you get all the bugs worked out.

 

Yea, it runs rich low-mid, but high it seems to lean out a little on the egt gauge. I could get it to 1500 if i tried in 4th, which seems much too high on only 5 pounds. Oh yea, stock ecu. I dont run the s-afc yet either.

Well, I have been running the z maf and 370s for a while now. After the rebuild actually. Real rich down low, kinda like now.

I havent had an problems with the maf on the non-charged side. Not sure why 4th gens have that problem, but I DO have a recirculation valve, so maybe thats why.

I modified the stock manifolds.

Intercooler is 7-8 inches from the ground now, havent scraped, but I have been careful. But lets not forget i am about 2" lowered already. Maybe more cause they have been on the car for so long.

Its hard to say exactly how much i spend cause i bought most of it seperately over a period of time, but i did buy the turbo/intercooler/wastegate from cheapturbo.com for 1200. A kit would be in the 2500 range, something close to that. I wouldnt charge an arm and a leg like pfi or anything.

 

No pics yet. I dont even have a full exhaust yet.

As for the rebuild, its everything shawn said it was, but as for the ve rods, the Z ones are the same ones. I have them in front of me to prove it.

And as for the car being sluggish with the lowerd compression, I wouldnt say it was any slower than before i did the rebuild. But i am not saying that it was in the best of condition before either.

Not sure when i can hit up the dyno, but like i said, i need to get the low end problem fixed, new colder plugs, then a boost controller. Then we'll see what she can do The track will be further down the road i am sure, but maybe late summer.

 

as soon as i get my car the way i want it, i'm dragging you to the dyno, i dont care how primative your exhaust setup may be
but we all know how long i take to work on my car, so you might have already gone by then :-P

 

a few more Q's

is it a good idea to pressurize the valve cover breathers

is the turbo mounted to the frame of thecar or just supported by the pipes

roughly where did you locate the oil drain in the pan and did you remove and drill the oil pan or just punch through and tap with it still atteched to the motor

what size oil lines did you use for feed and return

does your xover pipe run under or over the tranny

do you have full 3in exhaust or just 3in to your cat

how fast does the turbo spool to 5psi in 3rd or 4th

 

I didn't think that was possible.. unless you are talking about the center section.

 

it appears that the feed line in on top which is correct for good oil drainage but im sure both of you already knew that

 

yeah, i thought everything looked fine on it. that's how i have my turbo sitting but with the compressor turned a bit differently.

 

Its great to have another VE-T in the ranks. Please keep us updated as much as you can.

 

i can answer most of your question...
valve cover breathers are open air vented..not hooked up to intake. i'm sure we'll eventually just bypass the PCV system and use an oil catch can

IIRC, turbo is supported by just the pipes, i dont recall him making any brackets for it.

the oil return is to the drivers side of the front motor mount.

no idea on oil fittings/line sizing

crossover pipe runs over the tranny, this isnt a reverse ypipe setup.

exhaust last time i saw the car (2 days ago) consisted of 3" downpipe. hes going to make a full 3" catless exhaust, i believe its about half way done now.

as far as spooling goes, its interesting because there is some kind of electrical problem below 3500 (all signs point to knock sensor) and will not for any reason make more than 2psi. as soon as the ECU ignores the knock sensor it spools pretty quick, 5psi by i'd say 3800rpm in second gear which is pretty good, 300rpm gets you 3-3.5 more psi. that also gives you an idea of how much the 3500rpm mark changes the spooling characteristics.

julio, if anything is inaccurate, sorry..just correct it.

 

That is one sweet boosted max! I like to see the VE's with turbo's, it gives me something to dream about Nice job

 

I removed the pan to tap it. Its tapped in the upper pan (above baffles).
-4an and -8an lines. As far as spooling is concerned, pat is right. 2nd gear doesnt see any boost until after 3500, 3rd and 4th see boost sooner, but is very limited until after 3500.

Anybody know someone with a consult in my area????

 

Just for a LIMITED TIME ONLY ie.. a day or something. You could try bypassing the KS with a resister. Just to see if that helps things any. After driving the car around for probably less than 10 min (if it's warmed up), you should know right away if the KS is seriously retarding the timing

 

why not permanently bypass it...truthfully do you guys think the KS is even necessary?? especially being that he is 8.5:1CR...HUGE safety margin! even so the OEM over-sensitivity might even be a damper on performance. I've seen plenty 10:X CR Hondas go over 10lbs consistently with stock KSs disabled....I've run my Teg a few times with KS disabled(using my rom editor) and had 0 probs. again I'm only speculating though

 

Well it's a cheap thing to try. IMHO, I think the low end is soft because of two things:
Stock ecu +
1) Big injectors/big maf (rich)
2) Low compression (incorrect timing/fuel maps)

 

 

Julio you need to get a wideband or go to the dyno to see your A/F, if your seeing high EGT's at high rpms you need to either richen it up top with a AFC or a FMU and lean it out down low with a afc or ajustable FPR.

and id definitly try bypassing the KS to make sure thats the problem

 

He was saying that he tried that, and it didn't make a difference. But then said he could unplug the KS and it was lacking, then he would plug it back in and it would get power back, but then start being all again.


hmmmm.

 

I would speculate the Z32 MAF is part of the problem. The ECU needs to be programed to use it and since it isnt needed below 350HP, I would swap the maxima MAF back in and see if that helps any.

 

Personally, I would of ran stock ecu, maf and injectors to start. You should be safe as long as you keep an eye on the plugs.

 

accually if he put the stock maf back in it would run alot worse with the 370's still in

all he needs to do is a little tunning, lower the fuel pressure at idle and add some fuel up top with an FMU or AFC and he will be fine

 

sweet ride...i like the look at night

 

I'd have to agree with that. Doesn't the Z maf put out a different voltage than the Maxima maf? If so, that could easily cause you problems.

 

Umm...That car looks VERY familiar!!!!

 

there arent any night shots of his car. the night shots are mine except for the white max, thats some local guy who i cant seem to track down. i think nevin sent me those pics a while back.

 

yes but it should be counteracted, to a point by the injectors. thats all tuning issues. the lack of power below 3500 was before the motor was even rebuilt so its got absolutely nothing to do with the turbo, the injectors or the MAF.
