Default Re-Building a 1990 Miata For Endurance Racing

At the beginning of this year I picked up a 1990 Miata for $2000 that was caged and ready to go Lemons racing other than the fact it wouldnt run.
A quick fuel pump it was ready to go! Unded up doing two races this year changing nothing other than the Timing Belt and adding a Spec Miata Suspension kit.
After this the engine is making some interesting noises and needs more power!

So I was thinking of going to a VVT swap, My question is what is needed for a VVT Swap? Im looking for a pretty comprehensive list if some one has one.
What wiring will I need to keep out of my current car if any? I will be running the MS3. This is a race car so alot of the swap stuff doesnt pertain. And whats the best way to get more power from a VVT motor while keeping reliable?

If only there was a prominently displayed sticky thread at the top of the Engine Performance section for this commonly asked question.

Is there a plug and play wiring harness for the motor?

No. You have to do lots of wiring yourself. You can search on here for a distributer who has most of the OEM plugs and pins for sale though. So you can try to build a harness as clean as possible.

If you have the skill set, I'd recommend building your own harness. We have chased more problems with old OEM wiring than I dare to count. If I were you, I'd skip the VVT and go with a 99-00 BP4W head. Similiar power, but less demand on the oil system is always a plus for budget enduro cars.
