I assume you have DIS (no distributor).

Wow...well you kind of have some wiring issues to work out. If you have
DIS, then you have to convert to the distributor system/harness/EEC of the
TC. The turbo 2.3's are also speed density and there are no real mass-air
conversions that work on the market (to my knowledge anyway). It sounds
like the motor alone might have detonation problems at 10:1, it will only
get much worse if you try and add 1 bar. Have you thought about nitrous
instead? It sounds like it would be much easier than trying to retrofit a
turbo on your engine.
