Newbie In Need Of More Boost

February 2, 2007

Hello ive just bought a import 185 1990 in maple red v rare colour and love every minute of it. :yahoo: just wondering if anyone could help?

It has a metal head gasket and an uprated fuel pressue regulator, full powerflow custom exhaust, is lowed, and has an aftermarket boost gauge.Ive also just bought a Blitz FATT turbo timer, BLITZ DUAL SBC BOOST CONTROLLER and a bailey dump vale.just wondering what is a safe boost pressure and what else i can do to improve bhp and torque without going over the top. :help:

cheers

You can go to 1.1bar if you've got all other supporting mods in place and working ok. Anything above that and you'll be blowing hot air with the standard turbo. I strongly suggest you get a O2 wideband sensor and a decent piggyback ECU set up before you do anything though. It'll give you a good idea of what your engine is doing.

But as above 12PSI (.9 BAR) is reasonably safe with what you have. I've run mine at 1.05 for a while without a metal HG and it was ok. Turned it down to .9 now though as I really don't want to do an engine rebuild just yet. :D .

Bear in mind everyone has a different opinion and different experiences with what can be done. If you want decent power and torque get over to gt4oc read some of the threads and go from there. Otherwise it could be a steep and expensive learning curve. :thumbsup:
