toyota celica gt-4 fuelcut

[BR0Z]

Hi

Pretty sure it's around the 14psi mark, unless it's the RC model which is 17psi .

Cheers, Mark

It seems to vary from car to car but around 12-13psi is normal, only one way to find out

what model gt4? and from ur sig i think fuel cut would be the least of ur worries.start saving for clutches,diffs and gboxes
my st185 cut about 14-15 psi , st165 are similar as well i think.the st205 doesnt cut til sumwhere above 18psi i think. unless you hav an RC edition gt4 or st205 then dont bother with anything above 14-15psi consistently as the wee turbos like to fall apart.plus the ecu doesnt hav fuel maps above 14.5 psi anyway , hence the fuel cut

WRC ST205 has it's fuel cut at 17psi. Their turbos have steel internals so they don't crap out so easily

yea i got the st185 and think it is time to rise the boost and does any 1 no wht the max safe boost is i herd it is arount 16 to 17psi???

Not with the stock ecu, turbo and intercooler it's not. The stock turbo doesn't give much more power after 14psi anway.

aim for 14 psi.you will probly need a fuel cut defender to stop it cutting out on colder evenings.. if you are smart and hav a decent air filter and exhaust fitted already , you will probly struggle to get a steady boost level anyway , so by aiming for 14 you will get anywhere from 13-15.

This is a link to a site that is all about tuning the 3S-GTE, in a MR-2 but Im sure that there are no major differences other than the RC models and the differing ECU. Might be way off but worth a read anyway.

yea i have an 2.5" exhaust and k&n filter. Is that true about the fuel maps only reading up to 14psi?

http://www.gt4oc.net has a very good forum covering the GT4.

Lanius has a fmic on his, there's sweet fa room in the stock front bumper but if you upgrade to an RC bumper it allows for a lot more space up front but there would be quite an increase in lag, If I were you I'd try and find a water-air setup unless you want the bling factor.
