I know it's not very helpful, but I did find some mention of the V-2 SQ Si-Trim by searching on Votech's website....

V-2 SQ S-Trim

The 350z heads have the SC-trim.

The best advantage over the T-trim, in my eyes, is the price. The Si-Trim upgrade is only about $350!

Not just the price but the increase in efficieancy too.

Is it really only $350? Are you sure about that?

Yeah, the increase in efficiency is great, but too me the price difference is more important .

As to the $350, I remember reading that in the thread I linked form my350z. The price is definitely buried in their somewhere, and I could be off by a little (but not much).

So, are you volunteering to be the first to go for the Si upgrade tsaulz??

That wasn't my intent, haha. We'll see about it this summer though. It depends on what kind of job I get.

Bump for the SI trim, lol.

LOL. Yeah, we do need to explore this more. If no one is going to go first (hint-hint tsaulz) and get the upgrade, then someone should at least call and verify that the Si Trim is a valid upgrade for the V-2 S-Trim and that it is $350. I nominate TJ_Max! All those in favor type "Aye"!!!

Lol. I'm waiting on the Dyno results from the my350z thread I posted above. If I decided to upgrade my blower, I'd be doing it to my V1 blower, but several guys on my350z have upgraded their V2-SC-trim blowers to V2-Si-Trims. I second the nomination of TJ_Max.

Ugh peer pressure.....

Here is where it was mentioned on my350z: http://www.my350z.com/forum/showpost...&postcount=104

Still might not be a bad idea for someone to call Vortech to verify.

Jose, are you going to call or not?

If not, I renominate The Wizard then.
