I've now got it at 23 psi on an MY93 WRX. Lets see if she'll blow up on me tommorrow at Santa Pod.

edit~ I had to as I've lost loads of accelleration thanks to an MY98 UK gearbox.

hi everyone its allan hudson here from dublin
i have a 94 wrx with a full bpm e system and piper x air filter and fcd ,bleed valve ,,im just wondering what boost can i bring it up to safly????????also have clutch judder but its not sliping also when lifteing of the clutch its nearly up all the way b4 it bites and sometimes sticks down half way after a good boost and change gear and iv to put my toe in and pull it up ,,,so what would us recamend thanks ,,,,,,

 

its a jap by the way thanks

 

40 people looked at this tread and not one persone was kind enough to help me out well lads thanks

 

i have a 95 wrx that i run at 1.2 bar of boost but i have a sti 6 intercooler racing dawes device fcd full de-cat and a bmc carbon cold air box.
also run a water spray system with a boost switch and a dawes afr guage to make sure its fueling ok.

if i were you i would get a dawes device and run it at 1.0 bar

 

hello allan
richard from brum
i have a sti 4 which was running perfectly and very well at 1.3 bar
i fitted a boost controler and tryed 1.6 bar and blew it up within 100 miles be careful mate its cost me a fortune by the way any one want a blitz electronic boost controler only done 100 miles(and one engine)!!?

 

I have run my MY00 WRX up to 2 bar without any internal engine mods...just enought fuel... BUT FOR REALLY SHORT PERIODS of time !
about 13 seconds...

 

AFAIK 1.1bar or 16.5psi is assumed to be the safest option without remapping, as urs is a jap that means running on as close to 100ron fuel as poss especailly if u up the boost

Cheers

 

Don't get stroppy because you don't get an answer immediately - I looked in, saw it wasn't my99/my00 so couldn't comment

 

yea but im sure ur not the only one to look in as there was 4o or so and i was dericting it at the people with info that did look in and gave me no help

 

i did!

 

AND THANK U TO THE PEOPLE WHO ARE WILLING TO HELP ME PUT THERE ,,,

 

Um don't attempt to whack on 23 psi on your car just yet. Take it up in increments and make sure your fuelling is okay. I'm just taking the risk as as I said, I've lost accelleration from the gearbox change.

 

WRX you sure your not from the moon???

WRX,
Paul McLaughlin runs Mac's power motorsport in Clane Co kildare so is only a few minutes down the road from you, you can mail him at

(his site is down at the moment) He should be able to help you out

 

On the clutch problem, I had a similar thing going on and cured it by adjusting the rod that connects the pedal to the master cylinder. If you look under the dash at the clutch pedal you will see that the piston has threaded adjustment. Loosen the locking nut and then turn the rod to suit.

Turning it clockwise should raise the pedal height and make the pedal return better. Antl clockwise lowers the pedal height.

 

PROVA Map a 94/95WRX to 16.5psi.
Compared to a Z4 standard ECU this map has no changes to the fuel map and a maximum of 3 degrees advance in some areas of the timing map.

If you don't have a Z4 ECU and have an earlier model maybe a U8 the standard fuel and timing maps are different (fuel map is totally different).

Z4 Labelled WRX ECU, PROVA and Prodrive all use near identicle and better fuel/timing maps when compared to Pre95(ish) WRX and UK Cars.

 

Hi WRX SCOOBY

I have a MY00 U.K running at 16.5 - 17 lbs boost(Dawes).

AFR shows in the green (RICH)(GOOD ) under all types of acceleraion throughout the gears. The MY00 ecu has a fuel cut set to around 17.5 - 18 lbs boost so I am just under that.

Make sure you have an AFR and Boost guage before raising the boost from stock especially with the JDM imports as they set their ecu's up on 100 RON. You may run into lean fuel mixtures with too much boost.
