Enough Fuel???!!!

Have been working on a 93 rx7 for awhile now, just wondering if the setup I am using will require more fueling.. Specs:

Atkins Street Port- Dowel Pinned Motor less than 5 Miles on it
Greddy Single Turbo Kit using a Garrett a/r60
Greddy Downpipe w/ external Wastegate
Apexi Cat Back
Underdrive Pullies
M2 Chip
Greddy Front Mount Intercooler/piping
Running 8-9 Psi on 93 octane
Stock Fuel system as far as I know

Should I upgrade the fuel system to run those low boost levels or leave it alone if I dont plan on raising the boost levels anytime soon??

your going to need bigger injectors, as soon as you start boosting, your going to start running lean

based on what you listed and not sure on some parts you have .. i highly recommed talking to a experienced shop/tuner to better guide in the right direction.. ported single turbo kit cara dont go well with a static M2 chipped ecu and stock fuel injectors.. your results will turn into a soon to be blown engine..

We need to know what HP are you going for, what turbo kit you have, TDXX , TXX. What amount of boost do you plan to run? Etc.

No plans to go any higher than 10psi as of right now, maybe next summer up it to 15 with the right upgrades... I believe the kit is the td06, got the kit w/ the car and no paper work..Hp numbers are not a concern at this point, just want to get it on the street and put a few miles on it...

try searching as this has been covered numerous times.. personally i like the 850cc/1600cc with a Microtech LTX8S but again theres other choices out there!
get a set-up your tuner is familiar with

good luck
