Is it possible to do a 4ag (big port) head on a 7afe with the same wiringand map based ECU?
I know that it is better to change out all wiring and ECU, but it it possible to use the wiring that is already there?---the reason I want to do this is I only have my car to drive right now and I drive 20-30min. to work everyday, BUT I think that my 7A head is what is holding be back from getting more power. Any help and/or even alternative is appreciated- I just need more power. Also I have just bought and am about to install a b16 manifold w/7a flange,38mm tial wastegate, and a GT3076R ball-bearing turbo. -------------------- If anyone is missing NASCAR and it's not on Speed Channel, take a fistful of Skittles, throw them in the toilet and hit the flush handle. Instant NASCAR!!!

I already have a turbo on my car and have a tubular B16 manifolf and my JGS flange should be in Friday I have my fuel system set-up with
1.Walbro 255 fuel pump 2.-6 fuel lines from tank 3.Aeromotive FPR 4.RC 550cc injectors 5. Apex-i SAFC II v2 Hopefully this should be more than enough fuel, As far as the external coil I would like to run it - BUT is the 4A a distributor-less ignition system??? I know that IF it is a DIS system there is no way to swap head without harness. -------------------- If anyone is missing NASCAR and it's not on Speed Channel, take a fistful of Skittles, throw them in the toilet and hit the flush handle.

[right][snapback]333769[/snapback][/right] the AE101 4agze was DLI and map the 4age red and blue were external coil and afm if you go and look on club4ag.com you'll probably find most of your answers I'm 99% sure you need to swap harness with the head swap or go standalone the fuel maps on the 7af ecu even with piggy back need alot of fine tuning to get right and the difference in distributors and other sensors save your self a head ace swap harnesses -------------------- yea your 3sgte is cool but ill stick to my 7agte
