Wich one would you swap with? VVT-i or Non VVt-i , and why?

 

tough question to ask

 

whatever you do dont buy from venus auto.

IMO, i'd just build your stock GE motor, and add the GTE head.

 

NON VVTi would be the way to go.

Tuning availabilty

Motor / power capability / dependability

 

Keep the GE engine and go NA-T that would be another ruote.

Lol....I disagree with all you guys, lol....

I bought my motor from Venus, arrived on on my doorstep across country in 4 days with everything.

I would go Vvti, newer technology, same strength as a non-vvti gte motor. Yes, the vvti is a little more difficult to work with but HKS makes cams for it, not that big of a deal.

You will see more power on bottom than a non-vvti motor with just as much on top because of the vvti system. The bottom end on a Vvti Gte is the same as a non-vvti Gte, strength is a non issue.

 

If your standalone engine management system can tune the VVTi, then you'll decrease some lag out of a dig. In these cases it would be beneficial to run the VVTi motor if your ecu can tune for it.

 

Well, stock for stock the vvti is making quite a bit more on bottom, I compared dyno's between multiple cars and the vvti was making quite a bit of difference. I agree tuning is more difficult but the F-Con Vpro is fully capable of controlling vvti, they even make a plug and play harness for the Gs/Aristo...Can't wait to get mine

 

You mean this one...
