Really nice mate. The ST205 has, what is basically an MR2 Revision 3 motor. Not the strongest block, but will see you well into the low 12's without major surgery, and should be capable of running 18psi through the CT20b all the way to the redline. If I could suggest anything to improve performance, it would be, cooling, cooling and more cooling! Get yourself a real decent FMIC. The one you have doesn't look to big (but it's a good start). The rest of it looks well sweet mate. Bet you're well chuffed. EarL.
