7AGE Options

[WH95TE]

Ok, so this seems to be my only option for more power, gettinga 7age, and eventually getting a turbo. I've tried looking around Club 4AG and that place is just a mess and confusing. So with that said, i'd just like to know about this mod.

1. What are my options and what kind of results can I see with them?
2. What exactly would I need to do this?
3. And around how much would it cost?

The last question not being as important because I will probably head to a junkyard to see what I can find.


If there is a post with all this information, just point me to it. Thanks

You can get better numbers out of the 4AGE heads compared to a 7AFTE though, right?

depends on the boost and where in the rpm we're looking at.

Assuming both are of the same turbo configuration and boost... the 7AFTE will make more torque around 2500-4500 rpms... but not as much horsepower overall because of its inability to flow as the revs speed up. The 7AGTE won't make as much peak torque, but typically speaking, will peak deeper in the rpm band (4500 rpms +) than the 7AFTE and will make more power because it can flow more, deeper into the rpm band. All this does is make for different types of engines. Consider the 7AFTE a better suited engine for drag racing because of it's larger torque (which isn't actually that great for FWD cars... hehe)... and the 7AGTE would be a better engine for track racing because of its more efficient use of available power.
