This weekend i got things cleared up alot on the car i put a nismo FPR on and my ported 2k2 IM and now it pulls too 7000 I bet i will be close to 400 now it spins like crazy in 3rd all the way to redline on 19s time to dyno again soon.

Good...

Did you get the boost spiking figured out? What size WG are you running?

Tilley: You should bring it to the MIR meet in MD in a couple of weeks. Go to the DC forum for the thread that gives the date. I'm sure we'd all like to see you run against Mardi!

Dyno's are nice, but they only tell you how much power you have. Putting it to good use is a whole other issue.

Regardless, I'd like to see it up close myself before I let Addea and Corey start playing with mine.

38mm i think its too restrictive for the airflow i have.

I agree...bolt on one of these to V-band clamp a 44mm:

I know some guys with 600hp cars running 38mm gates. That's what I have too.

IceY2K1

iTrader: (3)

Depends on the boost and turbo size also....the larger the turbo and the lower the boost, the more bypass air necessary.

Are those friends TT cars, Neal?

Nealoc187

iTrader: (23)

They are DSM and Evo guys. Running GT35R, GT40R, and one guy with a Holset (HX40 I believe).

I don't know if they have their gates sized properly, maybe they are running way smaller than they should be, but that's what they've got.

So does the stock 2k2 im that bad for boost? why?
how did you port the other one?

IceY2K1

iTrader: (3)

4G63 w/GT35R in the 600+whp range are running 35psi or so and pretty much all a GT35R can put out.

Who do you know running a GT40R on a 4G63?

GT40R or GT42R?

Neal knows these guys?

Might be the WG spring. if its too small and you running near double its rate using an EBC this can cause the dyno to look like that too. Put in a 1bar spring and be done with it.

I dont wanna blow it up i know the Z guys break anywhere over 420whp.

95turbo gxe

iTrader: (25)

umm may be a dumb question but what breaks at over 420whp

chris'smax

iTrader: (3)

nahh, as long as the tune is correct they are running well over 500whp on stock internals.

I30tMikeD

iTrader: (8)

Not 420. 500 is more the limit. APS TT guys run 450ish on 10-11 psi all the time without much of a problem. BriguyMax has been running that for a while now.

Nealoc187

iTrader: (23)

I know a number of guys who are running 450+ in chicago alone. Charles and mcderns (can't remember his name but he is a friend of brians) both put 475+ to the rears and brian has been running 460 to the rears for 6 months now, all these guys beat on their cars HARD. bigbri put down 552 to the rears and he runs his car hard as well, that kid street races all the time. All these guys are on stock motors.

Those jokers who are blowing their motors on fisher price horsepower numbers are the idiots who go and try to raise the boost on greddy kits and don't realize that the kit doesn't have timing control, they don't have a clue what they are doing.

Nealoc187

iTrader: (23)

I don't know that guy. That guy is using a GT42R. One of the guys I'm talking about is named ian he lives in chicago, he's running last I heard low to mid 30lbs on a GT35R, last track numbers I heard from him was 11.x @ 129mph in a full weight car. Then then two local guys to me one has the GT40R I don't know what sort of boost he's running he's secretive about his numbers but my friend ran him at the track and he was running no time runs because he street races, but of course the #s still show up on the timeslip, he trapped 131 in a full weight evo. The guy with the holset trapped 128 in a Galant VR4 which is a heavy car, that car is full weight too.

Come to think of it there is also a dude named dan I talk to sometimes he's running a tial 38 with a 50 trim, his car trapped 127.2 last time he went to the track in the fall, but his car is stripped out and only weighs like 2800lbs with him in it so he's probably only putting out mid-high 400s.

TRue i did some research and i guess some guys broke the 420 barrier....i know about a year and a half ago no one seemed to be able to do that on stock bottomend.

TILLEYS99

iTrader: (4)

well looks like i will up the boost to 10 or 12 and see what happens on dyno...

JClaw

iTrader: (17)

Record on stock internals is 619rwhp IIRC. What blows VQ35's is overly aggressive timing above 5500 rpms. Pull it some, a conservative A/F and 400whp is cake.

Blu

iTrader: (63)

do a pull with the stock ECU and I guarantee you will be over 400 easily the way it sits now. That JWT program is garbage, I would run the stock ECU and J&S if I where you.

IceY2K1

iTrader: (3)

Whatever timing JWT uses on your VQ30 ECU will be fine upto the MAF limit.

However, my concern is fuel. Your AFR is pretty lean, ie stays above 12:1 and it looks like your injectors/fuel pump isn't providing enough fuel above 5500rpm since your AFR climbs from 12:1 to 13.5:1.

What is your injector and fuel pump/fuel pressure/system setup Tilley?

95maxrider

iTrader: (32)

Did you fix the boost spike? Are you gonna try and run without the JWT?

Let us know about the house party. You should be mostly moved in by now. I can bring some house warming gifts and maybe the trip

I30tMikeD

iTrader: (8)

I would be carefull about just putting the stock ECU in and going. But he should have 550 injectors since that is most likely what the JWT ECU is tuned for, in that case is should work. But don't know how the Vq35 comes in to play.

But on 8psi and the stock ECU he should be at or over 400hp easily. I just wouldn't think about that idea without the boost spike fixed for sure. If he saw a 12psi spike with the stock ECU his motor would be gone.

I think a great set up is Z32 MAF, 550 injectors, SAFC, stock ECU, and J&S. I have been Ok w/o the J&S but one could run a little more boost with the J&S and not be as worried. That is a great way to make good power with a decent tune for fairly cheap

SPiG

iTrader: (7)

Yeah it was a GT42R on that EVO8.

Ditch the JWT, port the IM, and check that boost spike and your fuel system and you should be well over 400whp.

Are you running a stock VQ35? You decided against doing the VQ32 again?

TILLEYS99

iTrader: (4)

Well my main problem was the fuel pressure, I got the nismo FPR and up it now it pulls too 7200. I was able to set AFC at 0 accross the board. before it was at +12-15 most of the way. I am gonna check my MAF readings and maybe install my Lightning MAF before next dyno.

It's about time you posted those numbers. Let me know when you move in so I can check out the new house and the collection of nissan's you're getting

Since I'm still a new member Tilleys99 do you happen to have a lead on manifolds. Or does anyone here?

pimpjuice

What's the setup? Are you running with a returnless fuel setup or do you have fuel return?

Some options: bigger wastegate, bigger exhaust housing, increase boost, or (if you're using an EBC with a gain option) turn the gain down.

I had a 38mm wastegate also, but I was running more boost and had a bigger exhaust housing and therefore didn't have much (if any) boost spike.

Pimpjuice, didn't know that you were still around man. Good to see you're back.

Thanks. Its been a while!

Its now time for some more modding

Actually I'm trying to find out which of the Garrett ball bearing GT series turbos would be good for the 3-3.5L engines , GT35R or maybe GT4088R or GT4067R ?

Cheers A .

IceY2K1

iTrader: (3)

GT35R definitely on a 3.5L...good for 600+whp, so no GT40s unless you're wanting to brag.

On the 3L, it all depends on where you want the power, GT30R(low), GT3530R(mid), and GT35R(high).

I hope some VQ swap Sentras or others here dyno these to show each turbos power.

Nigel did a "custom ported GT35R" on a VQ30 here: http://forums.maxima.org/showthread.php?t=361469
