Building a turbo 240

[fishtail]

I'm planning on building a couple of turbo KAs (dohc), and I was just wondering a few things:

1. What is the ideal A/F ratio for the motor

2. is it worth it to port out the head (money vs. hp gain)

3. can I run cams on the motor or is it too high compression?

If anyone could give some helpful input on this it would be greatly apprieciated.

Your ideal a/f ratio will depend on a variety of factors. That is what tuning with a wideband is for.

Browse the forum and you will answer all those questions. Its best to just read up on here then you will come up with the best setup for yourself.

Put a list of ideal parts together, post it up and get everyones feedback.

Safe is 11.5ish. Your setup and goals and what you do with your car needs to determine your a/f. How much power you looking for?
