I was wondering if anyone here was using one, I saw it on their site and it had it listed under DOHC, will it work on our 420a, and how good is it, thanks.

The neon has the exhaust in the back. So the turbo is running down. It might work, but i would make should it doesn't hit the fan. You could maybe mod it. But, it would be cheap to buy another brand. I feel.

the flange on our car and neons are the same (you can put a neon exhaust manifold gasket on our car although they are flimsier and not multi-layered steel like ours). Whether the turbo will be orientated in a position that you like is the question. You should be able to tell by looking at it though.
