I've been doing a lot of reaserch lately trying to figure out if I should swap the GTX motor I have sitting in the garage or just use all of the turbo components to turbo my existing motor. The GTX motor seems to be in great condition and it looks like it certainly has less miles than my current BP motor. My 1991 LX has 100k at the moment and the car has been driven well, never abused, so I figure that I still have a few good years left on the BP. Now, if I do decide to turbo my current motor, what can I use from the GTX? Obviously the exhaust mani, the turbo itself, and the injectors, but can anything else be used? As far as I know the pistons are lower compression. Would they be worth swapping? Is there anything to be gained from the cams or any other internals? Somewhere on the Miata board I read that the the GTX has hotter cams and a better flowing intake manifold. Can anyone else confirm this? I am just trying to figure out what route to take and it's proven to be a harder decision than I expected.
And yes, I do know that the BP has a better flowing head.
Any suggestions will be gratly appreciated!
