i am hoping i can get some feed back about a turbo upgrade (60-1 hi fi or to4e) for my 87 rx7. im trying to get an idea of what i will need to install the turbo, lets say a 60-1 hi fi. im hopefully looking to get my rx7 in the high 11s low 12s. also what size injectors should i used in the primary and secondary. i will be installing a greddy fmic, and a apexi safc with my hks f-con. the way it is now my best time is a 13.55@105.

 

I wouldnt recommend running a super afc, and a hks fcon, the fcon is good and gives changes to fuel maps, etc. but not really good for high hp. The super afc cannot really control the sized injectors your going to want to run. I would suggest running an AIC. You can run additional injectors in your manifold, and control almost any size, and depending on what aic you buy, up to 6/8 injectors, you wont need anything more than 4 though. As for the turbo, they are great turbos, they make loads of hp, you can see the topics in times/dyno section and single turbo section. There are a few threads about the power they can make. I have a few 60-1's at my shop, they are brand new. Let me know if you want to see some pictures of them, thanks.
