4A-GE red top in 6G ST HAtch Options

[teal_terrorGT]

Ok so today I went out and bought me a red 94 st 5 speed with a blown motor. And while I was at it I got a 4AGE redtop with it for 275 out of a prism GSI ...anyone did the swap before and how is the wiring.


I have a set of cams for it and a lightened flywheel.

so give me the scoop please

I am in the process of doing the same head swap. There is a ton of info on the 7-age engine all over the place. I am getting new hks cams, new pistons, rings, 4-age ECU, valves, and new bearings. From everything I know about the 7-age it's supposed to be a very good high rev engine with better torque than the 4-age because of the bigger block. I should be done within about 8 months I hope(pending money situations). Let me know how yours turns out.

Actually the block wont be able to withstand constant long high revs such as the 1.6L block because of oil issues, but it does produce more power in the long run.
