quite honestly, there aren't a whole lot of bolts used to install a vortech. its mostly clamps. just be sure you have all the spacers (4 or 5, if i remember correctly) that go behind the bracket and on the cog belt tensioner.

SP engineering, Turnbull does good work as well

Corner 3 Garage or Technosquare would be the only places I would go to.

I have heard and seen some of the aftermath that has really turned me away... But enough... I will not say anything more...

Not to derail this thread, but we've done many successful installations and tunes, not to mention cars that we've had featured in magazines. We pride ourselves on the high quality of the work we do, so to hear someone randomly bashing our work without any facts to substantiate it is surprising. We have successfully installed many Vortech and HKS supercharger kits. So many in fact, that we've seen all the shortcomings of those kits over time and developed our own supercharger kit for the G35 with the VQ35HR that vastly outperforms earlier S/C options for the G35 with much greater reliability; no chance for belt slippage or over-tightening, billet aluminum brackets that keep the supercharger close to the engine so there won't be any chance of brackets breaking, upgradable supercharger units to allow for scalability and greater power options, separate oiling for the supercharger unit to prevent cross contamination between the supercharger oiling system and the engine oiling system, complete turn-key fuel system and engine management to maintain factory drivability and much more.

hmmm... ok...

stock is best!

Fontana Nissan can do it!

We've done Vortech installs before (but we do not get into dealing with upgraded pulleys and what not, we can do a clean install on out of the box vortech kits).

OP, all the shops that have chimed in are more than capable of installing the Vortech kit, however I recommend you do the install yourself or with some buds; it will be very informative and it will help you figure things out much more easily when things go wrong, and believe me there will be things that don't quite work right, particularly the first time you put it all together. It will help you figure things out in the future when problems do arise.

And the Vortech is not a particularly difficult kit to install; you just need time and some patience to do it right.

If you are capable of doing this, I fully agree, there is nothing more satisfying car wise than working on you own ride for things like this. It's a long process but it's not TOO hard of an install to do. I think if you get to know your parts and car you'll have much more of an idea of how to fix things if anything does come up down the road.

Corner 3 Garage hands down.
