ok, i'm probably just repeating things that i've already mentioned to you over the email, but basically, the engine is as follows..
sr20de non turbo, makes 105kw, for a good front cut your looking at around $1000-1500
install process would obviously be similar to an sr20det swap, but without the turbo plumbing. (i.e. you need new mounts etc)
on the otherhand, i have been told that the ca20e has identical mounts to the ca18de, so for a little more money ($1500-2000) for the engine, you then have 130kw, and for realtaively tiny money, you can get the ca18det to 225kw with no internal modifications..
even more to think about for you :-/
