fuel management???

Post by **LADrifter** » Thu Apr 03, 2003 10:16 am

Just so you know I already did a search and it helped a little but I want to futher narrow my research into this project. I want to know about three to five good options for fuel management. I want to get 400to 450HP at the wheels? Please include approximate cost, the amount you can tune the system and also a good size injector for a daily driver running high HP. Thanx for your time

I would also upgrade the MAF to a Z32, along with what 93semax said. And don't forget to change to a GOOD clutch. I am running a OS Giken, not to good for traffic but it holds everything I can give it. TOO noisy though..........

140 x 6 doesn't equal 640 LOL

840 sounds more like it.

I just bought an Emanage /w support tool and injector harness to control my fuel management. The emanage is made to work with most Jap engines and the RB25 is listed. Nobody knows yet how well they work. It is an option, I'll let you know how mine goes.. PENDING I EVER GET AN ENGINE!

All the RB-T motors are listed as compatible.
