Infini IV

I am planning on getting the ThunderFabrications DP/MP combo, and hooking that up to a 3 inch Magnaflow muffler. So the exhaust will be pretty much unrestricted... I also have a cone filter intake, and the Racing Beat FCD. The fuel system is completely stock, so I was wondering if my engine will be fine with the soon-to-come exhaust setup? If not, then would a FD fuel pump and rewire alone be fine to supply enough fuel, or would I need to go with a Walbro + rewire?

Anything else I should know before I go ahead and get things together?

BTW, I have a 1990 TII, if that helps...?

Thanks!!

piece of advice you might want to let us know what kind of rx7 you have . do you have n/a or turbo ?

i have 91 gxl wich i am using rb header and 2 1/2 piping to the back dual out magnaflows . ther are very loud but it does give the car some extra hp

my 2 cents

I did... lol

hrm I dunno man~~~ I put on the RB turbo back and I am hitting fuel cut on my 88 T2... I don't want to put an FCD on until I have some fuel mods done first though. and I don't think a rewire will be enough.an FD fuel pump gives you 10-15% more flow I think.

Just get a walbro. Its only $100 and will help alot.
