4aghead Question, is it possible? Options

[dans_st]

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.

option 3

buy a block like i did do the motor on the side until its ready to go in that way you have your car most of the time.

if your on a budget go full 4ag harness i just started out with the bigport head and a AE101 map 4agze harness with dli but soon had to go stand alone it was easier and a little more expensive

or just get a 4ag full harness there on ebay alot the gts change over
