Info Needed On How To Get Upto 350bhp From A Classic Wrx

[south west motorsport]

Hello - i have a 1995 wrx import with a TD05 turbo, i have no idea on what the original bhp is, im guessing around the 240bhp mark but i would like to increase this upto around 350bhp,

Current mods include, walbro fuel pump, hks ind kit, 3" bore straight through exhaust, no cats, middle silencer removed and blitz nur spec back box, and soon to be fitted a front mount intercooler as soon as i figure out how the pipe work goes lol.

At the end of the month im getting a remap done using a simtek ecu, but id like to know what mods could or should be done to enable the biggest increase in power to save additional trips to the mapper.

Thanks

Ben

sounds like you have more than 240!....................Big D ( oxon R.O ) would be a better person to ask

Oh thanks Ed LOL

Ok 350bhp from a 95' WRX, here goes.....

On top of what you have done already you will need....

To fit your Front Mount Intercooler

Fit larger fuel injectors I think yours are 380cc, 440cc injectors would do but 550cc injectors would be better.

I am not certain what the max BHP the standard TD05 will make (Andy Forrest will know for sure) But I would suggest a larger turbo maybe a TD05 18G, or a VF34 or VF35.

You may need to run a different MAP sensor so you can run over 1.2/1.3 BAR.

Fuel pressure regulator.

There may be more but I will keep you updated.

I hope this gives you an idea of what you need to get 350bhp.

Cheers Iain

This was just a quick list though, I will add to it later a few other things worth considering.

Thanks for your input guys, i forgot to mention that i already have an adjustable regulator fitted, im looking now at injectors on ebay, theres some yellow 440cc ones on there from a version 5/6 sti, could i run the car as it is if i fitted some 550cc injectors, or would i have to wait and pay the mapper to fit them at the garage.

Where is a good place to buy new injectors for my model, also would they fit mine or do i have to have a conversion kit to make them fit. Also is there any instructions on here as to how to fit a front mount intercooler, im sure the pipe work isnt quite right on mine.

Thanks

I have all the necessary mods complete now, just waiting for my re-map on Tuesday with a simtek ecu, im really looking forward to it, I'll re-post next week with the bhp increase.

Got my car back yesterday and it made just shy of 300bhp, martyn tuned upto a safe level without putting too much strain on things, he'd recommended i go for bigger injectors and a TD05 20g turbo, basically the things that were mentioned earlier in this topic.

Oh yeah one other thing, i absolutly love my anti lag and launch control haha.

I would be very carefull of your Anti Lag it will fry your Turbo if you over use it and your Lauch control will kill your clutch also.

But i agrea they are lots of fun have it fitted to my sti
