Car has now been mapped with 850cc sard side feed injectors, as I was maxing out nismo 750cc. Now I should be able to rev the car right out with out worry.
That is what I thought until I was road mapping it, now I was near maxing out my Z32 AFM, was hitting 4.8v at redline. Found that couple of the fmic claps where loose so probably loosing boost at turbo was spining harder to compensate so sucking in more air through afm.
With that sorted I decided to remove the carbon canister fit my oil catch can in place of it, also decided to recirc the catch can as When I had it to atmosphere it was sucking in dirt and probably putting in some in the engine.
It all looks alot neater in the engine bay now.
Roll on the next RR'day!!
