Question for the bigger power people.
Hi all. I have a P1 currently running just over 400bhp. This has just been done with a few bolt on parts. I am still on the original gearbox and engine internals etc. The car has been running fine like this for over 3 years but is starting make some interesting noises so expecting the worst I am thinking of upgrading.
Does anyone know a rough estimate on price (I can do a lot of the work myself) and what parts I will need to make a reliable (as reliable as it can be) 550-600bhp. I am just wondering if is worth doing or looking after the car how it is.
I already have a front mount, equal length headers, 3in exhaust, oil cooler
I guess for starters I will need
Gearbox (preferably a 6 speed) , clutch and diff
ECU
Engine internals
Thanks for any help.

either a 2.1 stroker or a 2.35 stroker. 2.35 will be the stronger of the two. if you can get the 2.35 sleeved even better. for reliability i would convert to a 14mm ARP head studs. bigger injectors. gonna need 1000cc minimum if you are looking at 600 genuine horsepower. better spark, more fuel, massive turbo (rotated setup probably with external wastegate), better brakes, better suspension, competition engine and gearbox mountings, full 6 speed drive train including hubs and shafts.
then to get the full potential out of the engine you are going to need some serious head work with fancy cams and then a decent ecu to get it all setup.
basically sell on your 400hp engine and start again. if you want a genuine "reliable" 600hp in a classic you're going to have to dig very deep.

£15k doesn't come close to building a reliable 500+ car. I have just done this and picked up quite a few bargains and 2nd hand gear along the way. £15k, a few favours and a lot of luck might just get you 500 but I would budget for half that figure again.
But if you can run a standard P1 engine and box at over 400 for more than 3 years you obviously have better luck than I do!

2.1 stroker will set you back roughly 4500 fitted
brembos all round 600
heads (newage acvs) 500bhp is prob the max you can go to on standard heads 700?
6 speed non dccd 1300 - 1800
6 speed dccd 2300
suspension 600
gt30 / 35 1800
rotated setup > 900
aftermarket ecu 500 - 2000
it mounts up like im running 440 on an 03 sti and have spent a small fortune
apologies guys if ive missed anything out

3" exhaust
larger wheels to accomadate brembos
better induction
better FMIC
external fuel pump
braided fuel lines
external pump (044 or similar)
Swirl pot
billet fuel rails
adjustable FPR
Big injectors
Clutch to cope (compatible flywheel)
decent ECU
Mapping
better/ tougher suspension
engine and gearbox mounts
decent catch can
List goes on and if you can't do any of this your self then factor in some lobour costs too.
I could add prices but it will just depress me.

Just to further clarify my initial statement, as some are concentrating on the initial delivery of the initial goal.....
Can you afford to carry on with another wedge of cash if the engine (or major drivetrain part) goes bye bye?
If you can't, don't do it.
Going to this level of power without having a back-up stash incase things go **** up is foolish imo. This is one area that many many people don't appreciate and ultimately get burnt with.

If you just want a tad more power why don't you stick in a newage STI engine like a 04/05 low mileage with avcs and run 430-440
Run that for a while see how you feel
I've run mine for sometime now and really enjoyed it and now for me it's time to upgrade
