I currently have 550 primary and 850 secondary with factory fuel pump and T04E turbine, im using the power fc, and cooling system is 3 core radiator apexi front mount intercooler, and a oil cooler, big external wastegate

i was told if i upgrade my fuel pump/injectors i can get 400 wheel hp from the T04E easy


So is a Walbro fuel pump/ switch 850 in to primary and buy 1600s as secondaries fine/ good for this setup ?

any concerns ? or should i get 4x 1000's ?

 

550/1600 is fine. 4x1000cc is not a good choice.

are factory injectors 550/850 ?

whats the difference between 550/1600 and 850/1600 ?
would i also have to get a fuel regulator ?

 

Easier to tune for regular driving and idle. Tuners have a hard time leaning it out. It is recommended you get a regular with your fuel kit. A good quality one is the CJ motorsports one and even comes witha regulator and a place to mount it to http://www.cj-motorsports.com/cat014.htm

Also, don't forget low impedence injectors need resistors to run with our cars. The other better (more expensive) option is running the FJO injector driver which controls the injectors better then having resistors.

Minimal I would recommend is 550 primaries with 1680 secondaries. If you are reusing your stock primaries, I would have them cleaned and rebuilt.

 

I run 550/1300 with my T04E. Per Steve Kan, the to4e is only good for about 400 whp. Mine dynoed out at 391 whp @ 1 bar
