ive been reading threads upon threads about VB upgrades for the 5AT's and im still confused as to whether or not its for non-F/I. i only have a few minor engine upgrades (spacer, z-tube, rev-up airbox).

 

i just got mine done yesterday...im not FI...its a noticeable difference, people say its for FI b/c i believe it is needed when you go FI but it can also be used on NA...

 

It doesn't have to be used on FI

Most people don't invest into something like this without being FI though, unless they are performance oriented.

I am not FI, but I have installed it for a few people now.

I bet this will cut your 1/4 mile time down by .2-.3 sec

If you are FI, you don't want to be hitting the rev-limit so you need the trans to shift faster.

 

I still think its one of the best mods i have done esp since i have the twins.

 

yea its definately one of the best mods ive done so far...all i have is intake and plenum spacer and i can chirp 2nd and even 3rd sometimes w/ this upgrade...i was so excited last nite when i was test drivin it after it was finished being installed...
it was $650 well spent...

 

With American cars it was a company called Transgo.... who would that be for a g35?

 

transgo makes a kit for the G also...i believe summit racing has the lowest price for it at about $245 shipped...

 

Edge Racing Converters had the lowest price I've seen. $219 + shipping.

there are several threads out now. Read through and search if you still have questions.

The cars I've installed the VB on were all NA still, one had nitrous though.
