I need some advice on my build/tarck/drift/Quater mile car. Yes all three
I have a 1993 Rx7 R1. My goal is at least 350-400HP

So far i added a Greddy FMIC, Airnixs intakes, Koyo radiator, HKS Exhuast, Battery relocated to the trunk, Apexi ECU with commander, Blocked off OMP, rear diffuser, 99 Spec turbos, lowered on tien springs. I redid the vacuum lines to simple Seq turbo. Also it has no power steering and no A/C. I have not tuned it yet, its running at 7PSI right now. On stock rx7 fd rims.

Plans to do:
Block off air pump
Get new Belt/Pully(for removal of air pump)
Straight pipe cat
New injectors(not sure what size)
New fuel pump(not sure on what size)
Take out ABS(get a ABS delete kit)
New Duel oil coolers

Not sure how you would go about building a car for all 3 to be honest as usually to excel in one you sacrifice something in the other.

But what I will say is prioritise a differential in that list as its a great mod for all 3. Think a 1.5way would be a great balance for track and drift and drag. Injectors 1680cc Bosch secondaries should suffice but you said minimum 400hp so maybe to future proof 850cc primaries 2000cc secondaries Injector dynamics brand. Fuel pump, in tank the supra TT Denso pump is a good cheap choice. But the aeromotive 325lph is a cracking little pump and will cover all bases.

* To make 400 whp the twins will be near max....so fuel for that will work. Anything past about 14-16 psi and you're out of the efficiency range.
* Not sure why you blocked off the OMP. You could have run it with a reduced premix.
* Not a fan of the those intakes. They source hot underhood air. Would recommend something that sources ambient air. Regardless, with an open intake and big IC, you probably need a boost controller to avoid SPIKE.
* Be careful with too little exhaust restriction ala the straight pipe. That often leads to boost creep and a lean condition...which means a rebuild. Either port the internal wastegate or leave some restriction in, like a hi-flow cat or resonated midpipe. Boost controller will do nothing for CREEP.
* With the PFC you can eliminate all emissions...egr, double throttle, AWS etc. Not JUST the airpump. But agree you will need an idler pulley.

alright, i was looking up the aeromotive 325lph it doesnt say itll fit a rx7 fd. I was also looking at the rx7store at the aeromotive 340 stealth & A1000. I dont mind spending more money if needed

I blocked off the omp because one day my car crapped out on me and i checked the engine light, it was the omp so i went to take it out the thing that spins in there was seized and the tip broke off. it was kinda a pain to remove the omp so i decided blocking it off would be better for the long run, to not worry about it anymore.

ill keep those in mind.

i run the aeromotive 340 and have had no problems, and if your building for drifting forsure upgrade the oil coolers and add a water injection system
