engine

Im debating wether to get an sr20det or a ca18det. They are both good engines from what i have heard. It's probably harder to get parts for the ca18det. I autocross my 240sx alot now and at the last event i was at a guy had a ca18det engine swapped in. He said one of the main reasons was cooling issues he said when i asked y not the sr20det. The engine is cheaper to buy, but is not as poweful. Is it easy to modify it to get up to the sr20det?

does anyone know anything about the ca18det? i couldnt find anything on the faq

I know that thats what im gettin'. Front clip...bigger turbo(ive been told t28),FMIC, and some other stuff. Screw SR20s. Blingin' in the CA bizzatches.

thats one reason i wanted something different from someone else. But can someone give me any feedback for the engine. Can i upgrade it to the power of the sr20det and what is this cooling issue i was told about
