4AGE head on 7AFE, What is all needed? Options

[onnaj]

Hello,

I'm considering (in the future) to put a 4AGE head on my 7AFE block and create a 7AGE.

But I'm wondering what i'm needing to make this work. I searched on Club4ag.com but can't find the right answer.

I don't look for mass hp increase but i hope i can get somewhere near 130-140 hp and even a bit better torque

This is what i know i should use:
1) the 4age head
2) 4age inlet manifold
3) 4age exhaust manifold
4) Porsche 914 timing belt
5) 7afe head gasket (maybe a TRD one?)
6) ....

Can i stay with my standard exhaust system or does it has to change?

And most important for me: Can i stay with the standard 7afe ECU so no new wiring has to be done?

Thanks!!

Just out of curiousity... what's the gas mileage on the v6 vs 3sgte? I know we cant go off of the specs of which car it came out of because as I am familiar with hondas...

A gsr swapped civic will get better mpg than a gsr itself. Less weight hauling.

Finally something I can halfway answer. The 5-speed Camry Solara with the 1MZ-FE V6 got 21/28 with a curb weight of 3,263 pounds. The Turbo MR2 with the 3S-GTE got 20/27 on premium fuel with a curb weight of 2,888 pounds. They say for every 100 pounds that's 2% to fuel economy. Let's assume a V6 swapped GT would weigh in at 2,550(Stock it weighs 2,580 and the 1MZ-FE weighs less than the 5S-FE) so that's a weight savings of over 700 pounds. So that should make for a 14% increase in fuel economy. In theory a V6 Celica should get 24/32. Which is sad because the stock GT with a 5S-FE got 22/28 with 65 less hp. Even if you got the Solara's mpg, which you'd get better, that's still a loss of 1 mpg city for an extra 65 hp. Personally it's my choice for when I swap, and am looking for a rear ended Camry/Solara now. Cheaper than a 3S-GTE, better fuel efficiency, can get all the parts for local parts house, no turbo lag, etc... That and pulling up to a Honda Civic and revving up your V6, must be a great feeling. For me it's the best option.

...And THIS is why my plans for my car change every 5 minutes. Hell, with a 1mz in a 2600 lb. car, I might have a faster car than my buddy's 2004 Dodge Stratus R/T 3.0, which is 3250 lbs.... It'd be a lot closer, for sure!
