1uz vvti questions?

[Mr.Cheeto]

Ok so most of you have read my idea on the Toyota 5.0 and after talking to a couple engine builders and taking in some advice from the forum it came clear that I would be way in over my head so I've decide to build a 1uz instead.

My questions are I've read on here and veight.com that on the later 1uz's that the rods are the weak point correct?
If so are the early 1uz rods interchangeable with the late model engine?
Are the cam selections as extensive as the earlier engines?
How difficult would it be to swap a vvti engine into a first gen Sc4?

I know that these questions are kind of broad but the search function isn't being friendly.

Any advice is appreciated and hope I'm not being annoying with all these questions and any more to come.

Latter model cams are hard to come by...
They use these engines in N.Z Super stock ..Producing good power...
In excess of 450 h.p..

So someone there MUST re-grind std cams ??
Check with Gloverman...
Check local cam guys who do twin cam engines..??

Wade has these cams sussed and did Ed's for his n/a screamer.

Hi there

See the below link.
It is a good description of the rods. In short; yes they can interchange but you have to re-balance the crank assembly.

Shouldn’t be too difficult, as long as you can get the electronics to work properly.
