Does this mean same fuel filter head and filter?

[mulerose]

What transmission changes if any?

[TanM998]

yes I believe the fuel filter is the same...

as for the trans there was a new calibration for the increased power... but I am not aware of any other changes... there are always continuous improvements made with these products..

Plastic endtanks on the intercooler...hmm, hope it doesn't BLOW THE ENDTANKS OFF at high/over 30psi boost like stock Toyota Supra Turbos would when modified for more boost...(potential for) uggghhh...

The transmission changes I heard about were the addition of another solenoid and the increase of idle fluid flow to solve cooling issues in stop n go high temp situations. Not upgradeable for 01-03 as I asked. :(

That's too bad here I was hoping we'd be able to use gas when it's cheaper.Stu
