hi folks just bought a 1990 s2,its got scorpion exhaust,k+n,front mount intercooler,new engine
the ecu is chipped,but is only running 8psi
how do i turn the boost up and to what safe level
do i have to turn fuel pressure,
any help or advise

 

U TURN THE BOOST UP BE SHORTING THE ROD ON THE ACTUATOR (TURN IT) BUT WOULD RECOMEND IT TAKE IT AND GET IT TUNED ON A ROLLING ROAD THEY WILL DO IT ALL FOR YA SAVES U BLOWING YA ENGINE

 

same as 320 says,
or if ya want a bit more by a bleed valve and turn up to no more than 11-12 psi @most without a rollin road session

 

Don't whack it up blindly - best leave it as it is and get down to a tuners to get it done properly....

 

It will need setting up by a reputable tuner otherwise you risk loosing your pistons in a big molten mess of aluminium....

 

Hey mate, cheers for today

Clean car u got there - give Stu a call about a setup - wrekon she'll go well

 

Fireblade, sorry for being cheeky but where did you get it from?

 

got it off lee reynolds from yorkshire off this site
pics are here somewhere

 

kin ell - KNEW i knew that car lol

Nice car

 

Best to find out what chip is in the ECU, this is the way to find out what boost the car could run and go to a tuner and have it set up properly.
Apart from that you could consider to mount a lambda sensor in the exhaust and wire up a air fuel gauge. Than you always know the mixture.

Cheers
