What is the biggest choke point in the 1uzfe?

I guess I am asking what could be changed to up the power the most in stock trim?

I assume cams are mostlikely it?

The 1uzfe really falls short of what other v-8's make in the power/tq dept as the v/e is laughable if you think about it as Honda's make more power in almost stock trim from a 2.0 with no turbo or forced induction.

Just have been thinking about it lately

the problem with the ve's isn't the engine, it's that the factory engine management sucks.

I agree that it is way conservative so if a standalone were to be swapped in place of the stock ems apx how much whp could one pick up?

 

[4U2QUIK]

so far with a very very basic tune we've squeezed out 30+hp and 30+ tq.

Wow that's pretty good and that all must come from ign mapping I assume?
We are talking non vvti correct?

 

[4U2QUIK]

non vvti, and most of the power came from just fuel map only. no timing yet.

Haha very true but this is the case with any engine but the 1uz seems to require much more than most.

 

[4U2QUIK]

true, but not true at the same time. If you have time to do lots and lots of research, and calling around, and some ass kissing, You can do a lot to the 1uz on a budget.
oh the duality of the 1uz build........
