7afte or 4agze? Options

[hashmaster52]

ok. i have an st and i dont have the $ or skills to do the 3s, so i want to either swap in a 4agze or turbo my 7a. i just wanted everyones input or opinions on wut to do. also, would a 4agze swap have the same hp as a 7afte? thx.

7afte is going to be as much work or more (rebuilt bottom end, custom header/downpipe, piping for tmic or fmic, a/f management, oil and water lines, etc.) than a 4agze. there is a good amount of aftermarket support for the 4a, and you'll probably get more reliable hp out of it.

as for hp, how close the numbers would be depends on too many turbo variables (what kind, boost pressure, eng managment, etc) to say. if you were to go big and run 9-10 lbs you could put up big numbers, but you'll need a huge amount of other engine upgrades too.

i vote 4agze.

ok doing a 7afte is no where near as hard a a full swap

for one you can run stock internals on 7afe and boost go look at the how to sections is covers a 7afte build you are right on the fact that the 4agze is more reiable for boost application but thats exactly what it was built for.

ive done the 7afte and a 7agte builds

in the end it comes down to your hp goals and what the car is used for track,drag or just DD
