[PHA71L]

hi guys im new to this site my name is steve ive just bought the gtr a few months ago it has had a full rebuild with cp pistios rods race bearings metal head gaskit ported head better valve guilds ect still has stock cams cam gears vavle springs ect stock turbos and fuel system it has a mines ecu and eboost 2 full exhuast and stock intercooler ment to of made 255kw atrw on 13psi dose this sound right? how much boost can be ran safely on the stock turbos? ive heard every thing from 12psi to 18psi i was thinking of getting it dyno tuned to 15psi will this be fine? ive ran a 12.7 at 167kmh on 12psi bad start... and 12.7 on 10psi 174kmh first time at the track in the gtr

thanks in advance steve

Your running a VERY big risk mate. Using stock turbos on a built motor is asking for trouble and a very hefty repair bill

14psi is generally considered the limit. But as you have a built motor, i wouldnt be risking a turbo failure that could potentially kill your bottom end.

So 10-12psi would be the limit for me if i was you

They usually make ~250rwkw on 14psi depending on the dyno/day etc.

yeah im pretty happy how it is atm just want to get it re tuned to be on the safe side think ill leave it on 12psi

As mentioned, you shoudl be careful with the stock turbine wheels. As if they are still stock ceramic items they commonly come apart and score the 3 bores its associated with. Anymore than 14psi is asking for trouble but i know from personal experience they will come apart with less. Get some steel wheel turbos

yeah i think ill leave it for now and just get two bigger ones later on...the oil presure guage has stopped working now ive heard this is a common fault? is it the gauge its self or the sensor that dies? is it also true a rb30 sensor fits?

[TTT]

it has a mines ecu

Get rid of this..

[PHA71L]

are they any good? are they fully adj or are they just like a piggy back ecu?

[SLIPPERY]

yeah the mines has been developed for the JDM where the fuel is different

They tend to run mega rich from memory for safety sake

[GeeTR]

They're a re-chiped stocker I believe.

And due to being tuned (usually) for Jap fuel, they'll theoretically be too fuel lean, and too ignition advanced.

Just as Mines did, if you have access to the ERPOM burner and SW you can 're-tune" yourself (PM CEFFIE) With a new motor (and new huffers down the road) you'll be wanting something better down the road anyway.

With a fresh new motor, id be running stock boost for sure.

Both cluster gauge and sender can be dodgey; with that new motor id get a aftermarket one asap.

motor is well run in 8000kms now... it dose seem to run rich! i would change the ecu if i go bigger turbos...

ill get it dynoed first and check every thing out,

the gauge when it was cold it would work as normal then it stated to flicker to 0 and were its ment to be...then a few days later it stopped flickering.... once it was warmed up it would drop to 0 but no warning light or any thing, and now it is on 0 all the time... ill change the sensor first and se if it fixes the problem.... dose any one know if its true the rb30 sensor fits?

[PHA71L]

had it on the dyno for a dyno day mad 290hpatrw and it was very rich! 10s and dipping to 9s afr

mines ecu is only a chip also hmm time for the power fc i think and injectors... how much hpatrw will 550cc inj flow on 2530s?

a tuner also said with the power fc and a tune to 16 17 psi on stock turbos it will make 350rwhp fueling it up a bit more to cool the stock turbos for the high boost any thoughts?

thinking i will run 15psi max

[rb26s13]

you obviously arent f**king listening to peoples advice on the stock turbos. i had one of mine let go on 10psi

fair call...well what power have people made on the stock turbos? and how much psi? and other mods ect

[OFENSV]

hey was that yours at the SBO dyno day?

[donkey]

fair call...well what power have people made on the stock turbos? and how much psi? and other mods ect

hey r33 gtr power fc, cam gears, exhaust, filters, 170k 1 bar still on ceramic turbos, 240kwaw, 1.2 bar 280kwaw.....running quite rich,maybe i have freak standard turbos......next week putting on 2860s......sweet, will let you no condition of turbos when they come off haha

who's dyno and what brand......

[OFENSV]

[PHA71L]

thats what i thought...

[boosted_32]

thats what i thought...

Ive been running 1 bar of boost through my stock turbos all day everyday for the last 8 months, havent had any problems at all
