I have read and searched before asking!

I am building a Turbo race engine from a 3.0SC (930/09) engine and would like a little input.

The goal is some 400-450bhp, max 7000rpm, small twin setup (less lag), no silencer, big twin intercooler. Car MUST be track-able and I am not after ultimate max bhp.

No worries about space, fit or looks - it's a race car!

1) What pistons (and supplier) do you recommend. First I was going with the 3.0 option, but now somebody recommended 98mm p/c? (must then fit 3.0 crank!). JE, Mahle, Andial?

2) Is the 74.4 crank a must or can I stay with the (like new) 70.4 I have?

3) We were planing on using a 964 PLASTIC intake manifold with adapters - securely fastened. Comments?

4) I am running twin-spark, 102.6 fuel, what is your suggested max compression?

5) Would a factory 964 cam be nice in this setup?

Any more ideas? Please chirp...

Tom
