Ok so it looks like spark is going to have to be address at some point. Whats the upgrade for us? I have two MSD units for V8's which I'm told can be modified to be used on either a 6 or 4 cyl.
anything to watch out for?
and the fuel system...
return or return less style?
what injectors are currently installed being stock?
how do we modify the VAF or switch it to accept bigger injectors?
Dealing with boost why does the stock unit cut the fuel at 13/14psi?
if we want more out of these cars how far can we go before we have to start building the bottom end and working with the top?

 

Be nice to know what you are working with and trying to accomplish. The resident mind reader is currently out of town.
