VVT and VVTi 1UZ-FE specs

[EyesofThunder]

I am looking for some details on the 1UZ-FE VVTi engine for my Desktop Dyno program.

I need cyl head flow
Chamber size
Cam Specs (as much detail as possible)

Once I get a good baseline I can do boosted models too. And if anyone has the 97 and older 1UZ-FE specs, I am open to doing them up too. I can post my findings when I get it done.

I see internet data, a lot on here, which is great, but I never know 100% if it is 98-up VVTi or 97 and older VVT.

Thanks!

older engines aren't "VVT" at all. there's no variable valve timing on any lexus/toyota V8 before '98, with the VVT-i 1UZ engine.

Thanks, didn't know. I was thinking my sister in laws 94 Camry 2.2 was VVT, I remember putting the cam in when I put in a new piston and rings/bearings (yes you HAVE to check the oil and change it more than every 40k miles.....)

So I assumed they all were. I would see references to VVT engines now and then, as assumed they were just not the "i" versions. Yeah, I came the GM camp, so I don't know these engines yet. Gotta learn something new!
