Hello, i have a 93 Rx-7. I am getting ready to put a new motor in. The motor is a 13b street port. The mod's i will have include............a spearco front mount intercooler (28.5x6x3,) turboXS blow off valve, and cosmo turbos. My question is what fuel system upgrades will I have to make in order for this setup not to blow?
Thank You
Jason

cosmo fuel pump.....2x1300 or 1600cc injectors and a rail and regulator would be the best....however, you could just do the pump, and get by, but why not do it right from the start......also, have the old injectors checked and flowed by rc engineering....

You can use stock system I believe just dont run more than 10-12 psi. You only need fuel to support the amount of air that you flow. If you want to upgrade though get 1300cc secondaries and upgrade the fuel rail. Also you will need to upgrade the fuel pump. Suprfast just had a great group buy for a supra pump and im sure he can get you a good deal.

i would do the ecu and injectors depending on your budget.
i went with a large streetported motor etc etc.. with stock twins (dont have the cash for others) but upgraded to a walbro pump and a new ecu. you will get by fine with that. later on i will get injectors (later this week) and the rest of things.. for the break in, just get what you need to get by, you shouldn't beat on your car then anyways...
where can you pick up a new high flow fuel rail from???
