Ah, yes that's what I wanted to know.

You guys are right about TT... it's hard not to keep it below 3k. I'm just being conservative with my driving habits in N/A form

AS soon as i get the stage 2. I will let you know how it works. Its going to be some time till he ships it too me.

In terms of whine and belt noise Rotrex and HKS (Similar designs) are pretty quiet. Over an exhaust system I would say you would hardly know its there except for the bypass valve noises. Anyway this is my experience driving in my friends 350Z with the HKS system. Probably Shumby could chime in on whether that's the same for him but G's have a little more sound deadening vs. Z.

Is the low end power there for both the SC and the TT or is it just the SC? Would be nice if the TT also has low end power.

I have not driven the TT 370z yet, need to ask JB.
I think the torque on the TT comes in a bit later, peak TQ, which is why people say the SC has the better bottom power but of course the TT will win at the top.

i wish gtm had a pay plan or a credit card company to pay for this. i dont think i can ever save enough to buy this outright.

they probably would get a ton more sales if they had a financing option for the whole turbo kit + install

And/Or group buy on both the TT kit and SC kit.

oh i forgot to state how clean the GTM SC setup is a well...you pop the hood and everything looks stock except the intake pipes which look exactly like a cold air setup..super clean!!..the rotrex charger sits in front of the motor and low..it has its own oil cooler as well..i prefer this to the Stillen setup which sits high on top of the motor..besides lowering the center of gravity we all know that heat rises...Sam's setup is optimal imo.

Come on now...the effect on the cars center of gravity would be negligible even if you tracked it. Your heat argument is also kinda silly too since the gtm sc sits right next to the biggest heat source in the entire car, the headers. Own oil cooler = added weight and another possible point of failure. You are right about one thing though, it does look stock!

Forgot to look at the pro's of having the sc where stillen put it, such as: shortest possible route from the sc to the manifold = very responsive throttle, easy to access, no pressure drop in the intercooler, less weight in piping and gets more airflow to keep the unit cool.

Gotta look at all pro's and con's man. Just sayin'

Yeah, yeah, you're always "just sayin'".

hey every little bit counts especially when your dealing with added weight on the front end..actually the sc sits in front and is lower than the manifold keeping the heat shield intact..the oil cooler only wieghs a couple pounds at most (its small)...didn't one of the Stillen sc's actually blow a seal while on track?...i dont have anything against Stillen's product and i weighed the pros and cons for both..i just decided to go with GTM

Hehe, You and I can look at the same thing and come to different conclusions. That's what makes the world go 'round.
