I could be wrong but unless you get rid of the renix cpu and swap with the 91 and up its next to impossible.

The idea is still in the works. I'll have tons to read up on before I begin so I'll know what to replace. Thanks for the heads up.

'89 is a Renix. It is a bit tricker to supercharger but can be done.

Check out my site. Loads of information.
