Boost Controller In Stock R33

[rthom009]

Hey all, so I just bought an R33 and its completely stock other than the exhaust system.. And the previous owner had installed an SBC Blitz boost controller..

Is there any benefit to having a boost controller if the cars basically stock? I've been driving with it off lately because I was thinking it would be no good running the car at higher boost than normal..

I've tried searching but couldn't find anything, cheers!

So it has Stock Side Mount Intercooler? Stock Airbox? Is the Exhaust Turbo back or Cat back?

Does it have an aftermarket boost gauge? What boost are you getting now?

If it's a stock turbo with stock ECU then you could go as high as 10psi but it would certainly be better with a more free flowing intercooler etc...

Yep stock side mount, stock air box, and I'm pretty sure its a cat back exhaust..

No aftermarket boost gauge and running it at 7psi..

pretty keen to start upgrading parts, but yea wanted to know if there is any benefit to having that boost controller and what boost I should run

Just leave it alone for now imo, at least until you have some method of tuning the car. Then it should be an asset, and one less mod to buy.

Up to 10psi is in the Supposed safety zone for the stock turbo but also about all the ECU will handle before it gets all Rich & Retarded...

Get yourself a Just Jap Bellmouth Dump / Frontpipe, 3" Cat, some sort of Intercooler upgrade (either Frontmount or an R34 GTT sidemount) and get an R32 GTS-t 10psi Actuator. (or use the boost controller if you wish)

Have my luck turn the boost to 10-11psi give it a squirt up the street,

then blow the exhaust wheel into the cat

and turn the front wheel to dust

now the poor skyline is sitting there crying at me for a highmount but

bills and living expenses are more important

f**k my life yo

lol

It happens... Had a mate pull up in my driveway in his R34 GTT running 7psi on stock 34 turbo.

When he started it up again, there was a couple of clunking noises and suddenly it sounded like a supercharger and had no boost.

Exhaust wheel didn't break, it just fell off.

Luck of the draw doesnt even begin to describe the ceramic wheeled turbo failure scenario.

Im here in the UK atm and went to a GTROC meet. 2 stock R33 GTR's both on stock turbo's. 1 gets tracked several times a year. No problems..

I asked him if he was worried about the stock turbos or the oil pump tracking an old stock car like that. didn't seem to be.

I also had my '93 R33 GTST with stock turbo turned up to 15psi for 1.5-2 years. Never failed, just ended up upgrading the turbo to chase more power!

Go figure...

[rthom009]

Sweet! thanks for all the help!

Yea I think i'll leave it alone for now until I do a few mods, intercooler etc sound like a good start..

ohh man, that sucks.. I hope that doesn't happen to me! lol..

It is also best to leave it be n upgrade the turbo at the same time as the boost as there is also the chance the turbo can kill the motor when it lets go (turbine wheels bang on housings and send chunks of turbine wheel into the motor...).
