Hi all, i recently bouht a K reg 1993 early model subaru wrx import... it holds 1.2 bar boost, and has 72000 miles...

its got a back box, baileys dump valve, pippercross induction, 1.2 boost...

what more do i need to do to get 300 bhp or more?

and also what could be done already for mr to get 1.2 bar boost???

cherrs!!!

 

decat and remap?

 

as ariser said-do u know if you still have your cat downpipe on-if so replace that and for older cars a simtek ecu is prob your best bet-expensive but worth it-as your car was around 240bhp out of the factory u may need 2 look at a bigger turbo and injectors 2 get up past 300-also if u have the small slanted intercooler then either go 4 an upgraded tmic or go fmic

 

i think the td05 on the car is good for about 320ish

 

it depends on how your getting 1.2bar of boost, because if its done properly and you have you a decat you may well have 300bhp already, if the car is set up correctly.

 

You'll need a proper decat exhaust system and either a front mount intercooler or larger newage top mount intercooler mated to a TD05 16G or an IHI VF series turbo and 440cc injectors. Thereafter an ESL 'Live' remap will get you well over 300 ponies, no need for an aftermarket ECU. ESL currently covers V1-V2 classics, and V3-V4 classics coming soon.

 

what is the esl live map mate? as i thought u couldnt map the ecu on earlier models-id like 2 know as i was going 2 fit a simtek 2 my car after xmas but this may poss save me sum pennies

 

thanks guys, i currently got a TD05H turbo, and the car still does have the cat on it. its ot a Z4 ecu

 

I would spend £50ish on taking it to an Impreza specialist with a rolling road and get it checked out before splashing any cash on it.

If you post whereabouts in the country (i guess you're in the UK) and someone can point you in the direction of a GOOD specialist.

To get the boost you're getting i would suspect that there is an aftermarket boost controller/fuel cut defender somewhere in your car or the car already has an aftermarket ecu/chip set.

The Z4 ecu is only rated at 260ps (256bhp) i would open it up to see if there is an extra chip in it

This is a standard early ecu



bottom right hand corner (where the row of solder is) is where extra chips are placed


The cat can be removed as your car has an easier emissions test

 

The ESL live map is a daughter board that fits onto the row of solder in the picture i've posted

Standard intercooler?

 

If it's running at 1.2bar, you probably already have an aftermarket - albeit probably a non-mappable - ECU. Could be anything: Mines, PP-chipped, etc. If not that, then it'll no doubt be running some kind of MBC such as a Dawes Device.

You'll struggle to get remapped to 300bhp on your car's early little slanty TMIC. Normally in the region of 280bhp is about its limit (this is prob what you're getting now, if running at 1.2bar.)

Ideally you'd need to add a FMIC (or at least a STi 5/6/7/8 TMIC); at least 440cc injectors; a decat downpipe; Walbro 255; and a remap. (You should actually get IRO 340+ on your car's TD05 16g, if mapped on V-Power.)

 

Look at my wagon in my garage mate, it's all there for 320

 

De-cat, FMIC and a Polar Performance chip. My 1995 achieved 303bhp 290 ft/lbs at 1.1 bar.

 

^ serious question...any engine probs ?

 

Save up for a gearbox too. 3rd gear will go.

 

Most people claim that 1.1 bar is 280+

 

That's right.

 

95 wrx running 303/325 scooby ecu chip,uprated pump,headers,uprated tmic,decat and 1.1 bar of boost

 

Second is already gone! loool

 

Turbonator?

 

Anyone know were i can get Good Downpipes from, (Cheap)

 

Check on eBay for 2nd hand "bellmouth" ones. Pay between £60-100, inc.P&P, but no more...
