You could run almost any size turbo, although you'll be limited by the fuel system...and so you won't be able to make more power than 400ish bhp at the most.

Worst case...if you get a boost spike running a 61 or even a 67mm turbo, you'll more than likely run stupidly lean and end up blowing the engine :). Not worth the risk IMHO...although you can also run Meth injection (Meth is cheaper than race gas!) and you'll be able to run approximately 20-22psi (considering JDM 440cc injectors are used along with Meth) and that would give you some sort of "leeway" with regards to a boost spike. Again you would need some sort of S-AFC and a Meth Injection kit which has a progressive controller.

If you want to do something right, do it the first time around - it's not worth blowing your engine. If you're going to spend £2500 plus on a 67mm turbo, plus manifold, plus wastegate, etc...then why not spend another £1000 and get a proper fuel system? You'll be a whole lot safer and will also have the capability to upgrade later down the road.

Another thing to take into account is the transmission will NOT be able to hold more than 500rwhp - depending on your driving style the transmission may last you for several hundred miles or several thousand miles...unless you're going 6 speed.

20-22psi, T61/67 turbo, stock ecu, stock injectors, meth injection, S-AFC.......

:D

I'd read up on some real life experiences with regards to pure 99.9% Methanol injection - it's been done numerous times :).

You may be talking about Meth Injection consisting of 50/50 meth/water mix... :). There's people running 25psi on 93octane pump gas (equiv. to 99/100ron UK) and pure meth injection using one of Snow Performance's kits...?
