What boost is this set at?

[Z32spdstr]

what exhaust system is that sounds very nice beefy yet warm

[AZNiNjARaVer]

what psi and what fuel was used on this run?

[tt300zxkid]

hahahaha thats funny man because if you have a good tune alot of shit is possible unlike that bullshit u just pulled from your assssss

[tt300zxkid]

on a stock engine with a boost controller and a good tune i am pushin 420 hp and thats stock everything

[dhillskier75]

unless you got intake and exhaust i doubt it, cuz when you say 420 you are either making shit up or have dyno'd in, which in that case is at the wheels which would be like 150+hp.

[Clovergz703]

420whp? i highly doubt that. max our cars only make 400 on stock turbos

[martpav]

@Clovergz703 Wrong

[tt300zxkid]

ok well enough with the arguing over youtube its pointless... i have an upgraded fmic, switched boost controller from 8psi to 14psi, 2.5in downpipes to 2.5in to 3.5in straight pipe to single hks hi power muffler 12lb nismo flywheel with a stage 3 comp. clutch, and a tune oh and btw its a jdm engine. so yeah thats it...

[Cgtuba870]

Hello I was wondering what exhaust you where useing and about how much it cost? please and thank you

[Foxy300ZX]

even with my fully built motor and all my upgrades i still dont feel 100% safe pushing over 600 without a stand alone ECU, not that i commute to work at full boost :D

300ZX ecu's are stone age shits.

JWT ecu's are made in the texas hott and humid weather. Ashspec Z is more reasonable but not perfect for the individual car. I would always choose ASH over anything. He knows his shit well, and discovered problems on the JWT ecus.

stand-alone is always the best, thats "the new (expensive) thing".

[Foxy300ZX]

Stage 3 what?? ECU?

What the hell is a stage 3 ECU.

I hope you all know that there is no such thing as a Stage 3 ECU.

I have Stage 3 turbo chargers on my 300ZX with 740cc injectors, dual pop, and Ashspec ecu set to 740cc. This is just the minimum.

The stage 3 means the turbos are bored out to fit the GT28RS wheels, shaft, and seals.

My set up pushes 670 whp.

thing to remember is the Z runs completely off the MAF So the ecu is programmed for the size of the injectors

Anyone dissagree

[DVBEAZT]

It is posible to get those numbers the stock injectors can hold 400hp max and the fuel pump on an na can push 400hp and tt fuel pump 700 I am we have a club member close to that on stock ecu, downpipes no cats ams pulley kit boost controller

[ceelm]

why dont these people show the numbers on the dyno screen

[remusic8]

It is possible, i ran 15lbs of boost on stock intercoolers, stock injectors, and stock internals, as long as your ECU is upgraded and you run correct fuel along with proper heated spark plugs!

[fast406monte]

Ok I retract my previous statement and issue a new one. It's not impossible to do. But it is impossible to do consistently and safely with those mods.

[300zxTTz32]

Def. not impossible, but I know where your getting at. If you go to Ashley Power's website, they got 410whp out of a tt with just a boost controller and tunning. Pretty crazy! Most stage III tt's usually dyno at around 320-340whp. Sick looking Z though man!

[CeezarPie]

I ran'd it another true dyno and i pulled 380 hp an 388 trq this one was on a specilty z shop though the other one was on some honad dyno.

[fast406monte]

haha,first of all whats a honad dyno? second of all, you didn't answer my other questions....are you running stock injectors, stock intercoolers, and stock crank pulley, stock internals at 15psi? Achieving those numbers with all of those things stock is not only unlikely, but impossible.

[b00mface]

not impossible, but definitely pushing it.

[azzkicker999]

@fast406monte You can achieve those numbers with stock but it wouldn't be safe ^^

[martpav]

@azzkicker999 as long as you are running cold plugs 91+ fuel and not more then 14.7 psi you should be able to get these numbers or better and fully reliable

[XxthefailnessxX]

@fast406monte How are you not making higher ratings? The shop that built the Z I just bought tuned my Z at 15 PSI on z1motorsports 525 turbos, z1 stillen intercoolers, 555cc nismo injectors, larger throttle body, and fuel pump, etc, and they said it made 450hp. =\. Now if that statement is true, im not sure, but they build Z's for a living.

[martpav]

@XxthefailnessxX He must be running that thing @ 9 or 10 Psi, I have intake exhaust stock injectors, stock turbos and ASH chip and getting 359 whp @ 15psi

[XxthefailnessxX]

@martpav If not lower. Im running a bar and making 400 (supposedly) with 555 nismo injectors, full exhaust, intake, and z1motor sports 525 turbos, and a jwt ecu.

[zleepertt]

yea right.

[CeezarPie]

Hnmnmnm i have the same mods just specilty z exh and down pipes and my clutch is jim wolf i think the only thing diff is no logy wires and i managed a whoping 375 hp and 377 trq and after the guy tuned it i managed 404 and 418 trq he said the 1992 and 1993 are blessed with valve timming guess it might make a diff

[fast406monte]

This means you are running stock injectors, stock intercoolers, and stock crank pulley, at 15psi and reached over 400 rwhp? I doubt that. What kind of dyno was this on?
