probably going for water/meth injection as it's mainly drag racing I'm in to.

I really wanted to go down the efr road but it just wasn't going to pan out with the limited space I have, as I am heading more towards the drag racing I decided to go with a Gt as spool up isn't going to be such a big issue.

I think to get the best out of what ever you do you really need a engine builder to put it all together getting all the compressions equal and the cam timing right is what's going to make or break it.
