hi i have a 1995 classic wrx in white

im a totally newbie to the land of subaru

its been on a rolling road, been looking at what boost people are looking at and mine is running at just about 11psi, is this too low?
car has mines ecu, remapped, full exhaust system

on the rr it made just shy of 300bhp, does this seam about right for the mods?

Will put pics up when I get home, on phone at the minute, its white with black fibreglass bonnet, black wheels window tints, lowerd and 5inch exhaust, will upload pics later,
Guy who I bought it off said it was running at 1.1 bar, but on boost guage it sits just about 11 :s any ideas? Could I safely turn the psi up? Or would that require mapping etc thanks

Member myblackwrx has given good (and oft repeated!) info about the Mines ECU - see the many threads here:-

Hmmm not sure really are you running classic top mount or front mount if it's top may be 11psi is perfect and if your happy with the power I'd leave it .

Sacrilege! The previous owner has tinted the rear windows and applied the decals to the lower rear doors, as if to pass it off as a Type R 2-dr Coupe. That simply won't do!

Only kidding dude - nice clean early example you have there (and in the best colour ).

stickers are coming off, not happy with paint job on it as the moment, someone has resprayed the roof and done a shocking job, as its really dry, but im going black with the roof and spoiler,
unsure weather to keep the tints or not,

does the dyno graph look aright? im a totally noob to the world of Subaru,

do you think the psi should go up?

Looks smart mate tbh I couldn't say all depends on supporting mods like fuel pump, injectors, air filter etc may find if these are standard 300s the limit and I'm not certain on classic bottom ends like what powers advisable before having to do upgrades.

Graph looks okay.

Usually, the Mines ECU is a chip that overides the Subaru one and normally runs at 1.0-1.1bar (14.5-16psi). It's a generic map, not a bespoke remap (it doesn't have that facility). What with its aggressive ign. timing + your FMIC, I'd defo get your AFRs checked at a rolling road place! You need to make sure it's not running lean!!!

I'd defo run V-Power 99 or Tesco Momentum 99, as a minimum - nothing less!

guy who i bought it off said its running at 1.1 bar but could go to around 1.3bar,
im running on v power wont put anything less in it, sorry to sound noobie, but could you not use abbreviations im not use to the subaru talk yet so i have no idea what your talking about
would like to get it rolling road again as this one was a year ago, have one for 4 months before that one was done and it was runnin at 247bhp before that but torque was dreadful

i need to invest in a turbo timer aswell

also not happy that it has an open air filter as im sure it will be sucking in alot of the hot air from the engine, so i either need to get enclosed induction or run a cold air feed to the filter, what do you think will be best? thanks

No you don't. Waste of money. Just drive off boost for the last 1/2mile or so before parking up. It's THE BEST way to cool the turbo

It'll be fine as it is. But enclosing it and/or cold air feed is good to have obviously. You have to have the cone, because the FMIC pipe dictates that the OEM airbox has to be junked (no room for it).

Sell it on and reinstate the OEM (std lol) recirculating black plastic item. The car will drive better with it back on, etc.

Because you have a FMIC, you'd also have to contrive new connections (silicone hoses/jubilee clips) to get it fit between the DV port on the IC pipe and the DV recirc return on th turbo intake pipe. If all this sounds a pain, it's not a problem keeping your BOV... Does the car drive okay with it - no jerkiness changing gears and/or coming off boost onto the overrun, etc.?

No problems with driving if I let off the accelerator fast it will chatter, but if I let off gently it will just do the normal tssshhh, car drives fine etc

Keep your aftermarket BOV then, seeing as you're happy with its drivability.

BTW, if you dont like your tinted rear light clusters and want to return the rear end to factory, I have a set of regular non-tinted OEM ones, complete with original amber indicator lenses sitting around gathering dust. They are in extremely good condition - not even any hairline cracks/fading etc....

Thanks for the offer mate but I'm after the opposite, more black as I'm going for a black and white theme, can you mesh the front grills on the classics? Or do u have to buy a meshed grill?

The normal dump valve sound is there, just drowned out by the noise of the chatter, all runs fine etc tho

No worries.

Yes, you can buy sheets of thin black or silver metal mesh off eBay (square, diamond, honeycomb, etc. designs). Needs to be about 100cm x 25cm to overlap the space.

I had this sorted on my STi 5 by API - they did a great job in dexterously cutting out the central maw moulding with a jigsaw and forming/riveting/glueing the black honeycomb mesh into the resultant aperture. Very professional looking - looks factory.

Yeah it's pretty normal mate to hear the flutter. Lot of people prefer it and run a recirc valve so all you hears the waste gate flutter
