Hi

I'm new to this site, i recently bought a 1990 rs turbo, it was in a prety bad shape but so far i manged to fix most of the prublems and even come up to 20PSI with my little T3, it runs well (really strong!!) but not good enough.
The two next things that i want to replace is
1. fuel computer, right now im equiped with a cosworth fuel system but cant get to the right tuning.
2. MORE important, convert it to 16V, mabey a zetec cylinder head or a sierra 2000 cylinder head, dont know what will fit the engine and manifolds...

Can any one plz help, i went to the experts in ford (English people)
Thanke you guys in advance[/b]
