Let the can of worms open :D

Nothing wrong with more boost... As long as you got enough fuel to take it. The 20G's are a tough ol block, and can take a beating, but you gotta do things right! Leo is a case in point of doing it wrong for example. A stock car getting boost turned up to cut, run around like that for a few months (likely with no mech sympathy), and then the owner wondering why he cracked a piston and grenaded a gearbox. I'm fixing the diff tomorrow (seized gearbox fucked it)... As long as one knows what they are doing, then sweet as, enjoy :D

<Shale>: Blighter doesn't really have an accelerator pedal, it's more just a loudness pedal. You can change volume, but you won't go any faster.

<mjlqtown>: (Southern US accent) I'v excised the demon! This car is now clear!

<Reuben>: I feel like when you stomp the throttle in Blighter, it's like you've startled an old man!

New to the world of Subaru's, tried to search, but the lovely search engine doesn't like words with less than four letters.

What I want to know is that what turbo can I bolt onto my BC5 RS ? I have owned a few Toyotas in the past, and they have turbos you can literally just bolt up and have a marked improvement in performance and response with no changes to anything else.

I want the car to remain as visually stock as possible, and do not want a noisy drain pipe out the back, I understand that a divorced/siamese downpipe works wonders so will be fitting one of those as well.

I have a rebuilt tdo5 sitting on a v2 wrx atm, building a stroker block for it and it will be to small, also have a bellmouth 3" stainless down pipe if you require that.

Cheers Brian

Mad. Thanks for all the information chaps.

Must be an '80s engine design thing, free flow exhaust brings on boost cut. Just like 3SGTE's :lolz:

FBSBC5 send me pm please for what you want for them both :) The car is due cambelt, waterpump, idlers etc in 10k so will do the lot then :)

Might have to figure out why it intermittently cuts power first though. Driving along, it will just cut all power for a second, like a soft speed limiter. Very random though. Can drive about without it happening at all, but then another short trip will have it cut three times.
