G/day people, New members here. My house mate and I were given a '73 1200 coupe and where making it into a drag car. We got the motor to run and it has a average of 110psi to 130psi compression in the cylinders.

Now this has cost us only $60 bucks for the turbo and everything else was given to us, were doing it on a budget of as little as possible.

What we have also is a CT20 turbo of a diesel hilux (30'000klm old) and a 40mm side draught weber of a 2L escort and a 1200 manifold to suit the weber. Where having it as a draw through set up so no intercooler and I'm making the manifold for the turbo exhaust side etc.

The motor will be left stock except for a bigger radiator and a couple of other things.

What sort of boost level do you think would could go? We are not sure whether to run it on utilimate, avgas or meth.....

I've had 2 1200 utes and a 120y coupe, and my house mate had a 120y sedan all in n/a form and they all have done me well. I know that they can run in redline no worries at all but how they run under boost with a 9.0 to 1 compression ratio I don't.

Any thoughts... let us know....
