Is My Gtr Safe On 14psi

[GTRBOS]

hey all how yas going, tony here

today i got my blitz dsbc installed by PROTEK AUTOMOTIVE in preston, i have the r32 gtr 1989 model with the stock turbos in it,

the modifications to the car are:

apexi power fc

greddy adjustable cam gears+greddy timing belt

hks dumpipes

custom front pipe

custom 3" cat back, all stainless from turbo

straight pipes all the way through from turbos

blitz dual solenoid boost controller

the car on the dyno was comfortable at 14psi so the car is currently on 14psi,

its not a daily driver, its more of a weekend driving vehicle and racing the 1/4 mile every 2nd week or so

today my car produced 237kw at the 4 wheels on 14psi, what yous wrecken for the mods that have been done to it guys

please let me nkow, thanks alot and goodluck on all your cars,

cheers

That is pretty much normal for the mods

That is pretty much normal for the mods

so is that a normal power for the mods or is the car safe on this boost level???

The power level sounds about right.

While its 'normally' ok, running 14psi through stock turbos on an 89 model GTR is asking for trouble.

It should be safe, depending on the condition of your turbos. No one can say when its going to break, its mechanical, but common sence says 14psi is safe for stock turbos. My mate has an R33 GTR, stock turbos, just fitted apexi pod filters, cam gears and power FC, is also running apexi AVCr boost controler. Now he runs 21psi through stock turbos, has been for the last 6-7 years that he has owned the car. I took the car down to CRD for him to have the cam gears fitted and tuned, Jim almost fell out of the car when he saw what boost he was running, with stock turbos, I said, "Well thats what he always runs." which is true, car made 260awkw at 21psi. Jim turned it down to a safer 19psi and the car made 250awkw, now this is still well above what recomended and regarded as safe for stock turbos, but like I said he has been running this ammount of boost since he bought the car about 6-7 years ago and the car still runs perfect. Car is an R33 V spec. Its quick, people say it will break, but it hasnt yet and he flogs the shit out of it. So its like I said, its mechanical you just dont know when it will break, you just have to be prepared to fix it when it does, but the amswer to your question is: You are running the highest recomended boost level for your turbos.

Blitz, why is it not ok to run 14psi on an 89 model as aposed to other models???

[r32line]

89 model turbos are now 18 years old... i.e more tired/worn out. Pushing them hard is only going to quicken the process to their eventual demise.

i picked up my car today and my mechanic said my blitz dsbc is not that good, he said they are normally a good boost controller but my one isnt the best he says, on my dyno sheet the boost level is not dead straight, its spiking on the dyno from 15 to 16psi, what should i do, he said get a new boost controller(just the unit itself) so please guys does anyone know where i can get just the unit from, i also want the newer stlye blitz dsbc, i already got the solenoids so dont need them but just ned the unit asap please guys,

cheers people and thanking everyone for the help

Dont know if you can get htem sepertly, might have to buy the whole unit again unless you find someone who is selling a second hand part. I just bought a Blitz i-colour dsbc new from Japan $650 posted, my sister is over there at the moment, I thought I was getting a bargin till my phone bill arrived!!! at over $150 in calls to Japan!!! Anyway SUch is life, i guess. Good luck. I would first check that it is connected properly 1st and if it is and there is a still a problem then you should probably just buy a new one. Just take it easy till it is all sorted. Goodluck

you took it to a shit tuner man. i took my car there and dom told me 13 psi is safe as a house on my car. 2 weeks later the stock turbo blew.

and he told me my stock fuel was maxing out at 173rwk. what a joke.

i took my car with the same fuel pump to get dyno'd 6 months ago at creatd motorsport and i got 209rwk.

creatd ftw

[GTRBOS]

yer i know rob at creatd mait, good mates with him, nar dominic is pretty sweet mait, the boost controller is faulty is all he said and he said get a new boost controller and it will be perfect because its not the 1st time his tuned my car ive always took my car der,yer creatd are pretty good but i wil rather protek with the gtr or even racepace is sweet on the gtr

Lol, 13psi is pretty safe man.... stock turbo's do blow unfortunately there life is not infinite...

[R33GOD]

Lol, 13psi is pretty safe man.... stock turbo's do blow unfortunately there life is not infinite...

and my af ratio was 9:1 when protek done the tune. thats why the fuel pump was "maxing out"

13 wasnt safe for me especially after doing some research. i got a series 2 liner= crap turbo
