That's important as I want to maximise the number of cars the kit would work with, to minimise costs.
I'm starting to think there isn't a big enough market for these kits in Canada, I'd have to sell quite a few in the USA also. I also have the feeling that the best way to add FI is with new low CR forged pistons and then the price of the complete system goes way up.
I'll be working on a turbo M42 with one of the Metric Mechanic employees and if that works out well, I may offer a kit for people that don't want a completely rebuilt turbo motor.
Mark, low CR pistons is definitely the safest way to go, but they are definitely not required especially for 300hp.
If I remember correctly, this car has about 480rwhp @18psi on stock engine with thicker head gasket.
Also another good example is cardcounter's 328. He ran 650+ rwhp on stock engine with ARP head studs and thicker head gasket. I believe only at 700+ rwhp something gave in.
