We run an E30 Turbo M42 in BMW club racing. Those layered metal head gaskets aren't that great. They look good but in our experience they didn't work as well as the stock head gaskets. We run the stock M44 head gasket. As I'm sure you know, turbo motors give you the opportunity to learn a lot about head gaskets. IMHO I would go with the stock gasket and save that extra money for a spare stock head gasket. Regarding this build thread, it would be interesting to see some dyno results. We used a Dyno Dynamics which is a steady state dyno and allows tuning with partial throttle. What ECU are you running?
Hi great job. Do you control the ignitions coils with the MS??
yes i do.
Well, I'm stocking up on research at the moment. Once I finish the body work on my car, I might buy another to start building the M42, or just buy another M42 engine. I want to rebuild the motor, preferably make it a boosted 2.0 but due to costs, I might keep it at 1.8 and just get the turbo build kit from Vacmotorsports. I'll then do a mild head job, replacing anything thats worn out and then I'll contact you on turbo goodies. In all likelyhood, this project wont take off until the end of the year. But it is something that I'm leaning more towards than swapping a S52.
