GT Motorsports: 370Z Supercharger system development

m4a1mustang · 09-10-2009, 10:56 PM

If pricing is right and the gains are there this is definitely a kit that I'd go after. I am mechanically inclined and don't think this would be too difficult an install where I'd need to pay someone else to do it.

might be a dumb question but im going to ask it anyways. Does the fuel system have to be upgraded if you get the supercharger kit or twin turbo kit? I'm seeing you have upgraded fuel systems for the 370z? or is that for the 350? I'm still learning how the 370z engine works and whatnot, i know on my supercharger cobalt i had to upgrade to 60lb injectors to run my 2.8 pulley and then i switched to the harrop tvs supercharger i was at 89% idc on the 60lb injectors so it was almost time to go to the 79lb injectors. Just wondering will the 370z be like that? if not when is it time to change to bigger injectors?

Fuel system is part of the Kit. When add air you got to add fuel in a simple way .

Wow this has been some interesting reading.... I take it most people on here purchased the 370Z and never owned a 350Z? From experience the guys at GTM are the s**t when it comes to the FI world. I have had friends and personal experience that any TT build will be priced around 15k+ if you want the job done right and a supercharger kit from about 9k+. The fact is you will never be satisfied and you get what you pay for.

A lot of people jump into the game thinking they'll just buy the kit slap it on and good to go. Not always the case, you still need a tune, possibly different injectors, fuel system, gauges, upgrade the pulley (if you have a SC), an engine managment etc. These things add up real quick and will put you over the budget in a heart beat.

Of course the HR motor is a different beast in it's own from the previous VQ motors, so it's kind of like comparing apples to oranges. The good thing about the HR is it takes to mods well and produces the power. I guess as time goes we will really see what the true price of a good build will run. For those thinking the 6-7 range I hope you guys have a different credit card to put the rest of it on.

I look forward to the rest of GTM's results, I know it will be promising and better then any other kits put on the market.

^^^ agreed. However, doesnt GTM basically provide a turn key kit with everything you need included ie; engine & fuel managment, injectors, etc? If GTM installs their own kit does that include a tune?

racerxj17 · 09-11-2009, 01:05 AM

you guys all have it wrong. we need to have everyone post up they wont pay more than 5k just so that GTM will feel obligated to keep the price down. it might not work, but its worth a shot

whether we do the install or you buy the kit only and install it yourself , the kit does come with the tune It is part of the kit.

Any good SDS kit will come with everything needed to begin boosting ASAP, turbo on the other hand, is a different story. BTW, my friend Alex's Vortech V5 kit on his 350 cost $5600 installed, 8k? really? No sir, not at all realistic. If this kit costs over $5500 alone, my business will be directed elsewhere, Stillen, Vortech, etc. A Supercharger is supposed to be a good way to boost for considerably less, with 8k, i'll build my own TT kit.

Have fun!!

Let us know how your custom TT kit goes and be sure to post your gains and some pictures when your done...

Don't forget to get a huge piece of paper for your garage floor, as your 370z will be quite a beautiful paper weight parked right over it over the years it takes to make the custom TT kit functional.

I hope you sane fellow members understand my sarcasm.

You skipped over where he said he would go with a competing kit (assuming they costs less) and instead commented on a passing comment about building his old TT kit.

I said I could build my own TT kit for 8k, hell, even less. (This means putting together the parts for the kit, not bolting it up). Of course I would never consider it because TT's are neither reliable or practical. Back on topic please.
