Very true. None of us are but we would all suggest you either don't buy the JZA80 with the 2JZGE and buy the TT, or that you sell your NA JZA80 and put your 10K towards a TT. After all we're only brain surgeons. Razz

2JZGTE and GE bottom ends are identical save the presence of piston oil squirters for the GTE. With regard to the heads, the 2JZGE reportedly flows better than the GTE on the exhaust side, but given that big horsepower numbers have been achieved using the standard unported GTE head, it's probably irrelevant.

Here is a link to a page which shows my 2JZGE head flows, before and after porting.

The flows were done @ 10" water vacuum. As you can see the intake flows very well and only needed a bit of cleaning up to flow a potential 380 hp. The exhaust however is quite restrictive and there is little improvement in flow after 0.300". It required significant work so that it eventually flowed 81% of the intake.
