Hey guys maybe you can help me out here. Ive recently rebuilt my motor with 3mm seals and a street port and installed an apexi front mount. I still have the power fc and stock twins, however, i need to upgrade the fuel system. I am planning on installing the BNR 450hp set from RX7Store.net during the summer. So should i put 550p 1600s or 850p 850s or 850p 1300s. Ive also purchased the RP fuel pump and SX regulator.

If you're aiming for 400rwhp I'll go with 1300cc secondaries. Or if you go 850cc all around you'll only have 300cc less then 550 + 1300cc combo.

550cc + 850cc x 2= 2800 cc
850cc + 850cc x 2 = 3400cc
550cc + 1300cc x 2 = 3700cc
850cc + 1300cc x 2 = 4300cc


More available fuel is always better but decide how far you want to go.

You should probably go with the stock 550cc + 1300 secondaries.

You can never go wrong with extra fuel....

I say go with 550/1600. For a 400 rwhp goal you might get caught a little short with the 550/1300 (this is assuming you don't jack up the fuel pressure really high)

i ordered the extreme fuel system from rx7store. comes with the sx fuel pressure regulator, fuel rail, 2 1600cc bosch injectors, and a denso competition fuel pump for $8xx. very worth it in my eyes. haven't got the motor installed yet, but i bolted the fuel rail up tonight! looks very schweet! should be enough fuel to hold anything ya wanna throw at it!

Yah im going with the RP pack, competition fuel pump, SX reg, Al fuel rail, hp fuel lines/fittings and Bosch 1600cc with new 550cc NDs for 1200.

Spoolin93R1, really eight hundred? sounds like a deal.
I say that because it costs seven to "exchange" 1300,s
hmmm...
