Question: Am I spending money of my Type R to make it unreliable?

I am planning on De-catting, Uprated fuel pump and re-map with a new Simtek ECU.

BUT, although I am not expecting hugh power gains (310-320bhp I guess) I have been told I will be heading for a new gearbox etc due to breaking it

Its a V4 Sti with 42k on the clock, can someone shed some more light as I don't want to have to keep throwing money at it.

Thanks

Low mileage too...gearbox should have plenty of life left in it!

Agreed with above a new clutch maybe needed!

Car is standard so far apart from center de-cat. My mod list is: Front de-cat, Fuel pump and re-map (simtek ECU)

Should I be looking at a 3 port boost solenold and boost controller too?

Is there anything else that doesn't cost the earth I should get before getting the map???

I don't think you need the fuel pump for 320bhp TBH. Why are you doing it, are you going to slowly mod the car?

If going for future mods, really at some point you'll need the fuel pump, then turbo, larger injectors, Newage TMIC or front mount etc etc.

Mine is at about 360-370bhp and drives nicer than standard, so it's money well spent. Oh, my gearbox went at 38k miles when at 300bhp - for no discernable reason!

Well I've done a few cosmetic mods and fancy a few more ponys now

Thanks for that

So..... my engine can take upto 400bhp with turbo and injectors plus the stages before hand?

All help welcome before I start buying the supporting mods

My 2.5 STi 4 had 400/440 on the standard box with Simtek launch control launches like this: YouTube - Smeatharpe July 08 1/8th mile drag strip. Subaru WRX STI V Subaru WRX STI I've upgraded to the 6 speed now & I really don't know how long the STi box would have lasted, but it was just fine when I removed it. Your box should cope easily with the sort of torque you are talking about achieving
