Best combo of UZ block and head for N/A and Forced.

[haroon131]

Hello everyone,

I want experts to put some combination here for Max output as N/A and Forced.
like which generation block (1UZ gens or 2UZ or 3 UZ) with which head (VVTi/Non-VVTi).
I thank you all for seeing and replying.

forced all heads you forced the air trough it.
to optimum head for forced air, is custom made. But it takes years to defelopment.

Na, dont know, but custom heads wins over stock 9 out of the 10 times, bigger ports etc etc

best combo is 1uz/3uz vvti heads on a 2uz block with 92-93 rods(or forged) and 2uz plastic manifold for N/a . Cheaper to just build one...

stock 3uz has maximum torque out of all UZ's and about the same power as all variants of 1uz vvti. The torque can be further improved by ecu remap.

Dont we get 300hp and 350tq with 1/2uz hybrid and more with vvti?

Manual transmission. Stock ecu vs limp mode off + remap. 460ish NM on a bone stock 3uz
