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

but whats the difference in terms of reliability between the 7AFTE and 7AGTE?

(i am also weighing my options and thinking of going with the 7AGTE)

I think its the head design. The GE head can withstand the boost more because of the better airflow?

Anyways their both Toyota Engine.. they should be very reliable.. wait nvm.. turbo + reliable = $$$$

The reason for a headswap has nothing to do with reliablilty... although you could argue the 4AG head being a performance oriented head can cause a slightly heavier driver's foot... which can hurt long-term reliability... but strictly speaking... the heads (4AGE vs 7AFE) are put together pretty much the same and work pretty much the same (mechanically).

The reason for the headswap... power curve. The 4AG head can potentially stretch the powerband deeper and longer through the revs, as opposed to the 7AFE which maximizes its possible output, even force-fed, pretty quick, but can generate more low-end grunt for this same reason. Its a matter of taste in the longrun, because the FE head can take boost well and does respond very well, especially with torque... but when racing... I mean really racing... you're not gonna be at 4000 rpms very much...
