Crazy how many sway back and forth on this one. A buddy of mine owns a few local Chevy dealers and he said his Vette guys buy them often and can't say enough good things about them. The You tube video's are pretty impressive and the pictures looks pretty clean on the install. Hmmmm....let's see what they come back with the 370, maybe I'll just be the guinea pig on this one...

The vette may not feel the lag as much as the big engines have a good amount of TQ and kinda hide the lag but 4 & 6 cyl will probably feel the lag. But on my 2 turbos I was told the turbo provides the back pressure so you would want a bigger diameter exhaust for better flow. I was using a 3 in TBE w/HFC on my 2.0T engine and that exhaust provided another 20+ whp. The tune also ran the boost up to 19 -20 psi peak as they were small turbos meant for low end TQ and power.

Yeah, I was thinking about that too, wondering if the Torque would throw it for a loop. Surely there's a Z guy out there that's tried it and can tell us first hand. I have to think the 350z experience is going to hold true to our 370's. I'm going to search some other boards this weekend for comments.

I really don't NEED the HP, but it would be fun to run up on some 8's and show them what these Z's can do. Guess I could just pay the $ for the big kit but $13K or so would get another Sportbike to play with...

I'll let you all know if I dig up anymore solid info.

I have never seen a Z with twin rear mounts... Not that it wouldnt work... I just have experience with the Single... and like I said before the only problems we had were boost leaks... once we eliminated them there were zero probs....

Got a question, does having the turbo in the rear with all the tubing really cause turbo lag or is it still just lag depending on the size of the turbo? And would using a diverter valve instead of a blow off valve help by recirculating the unused air back into the intake? Guess that really makes 2 questions.

also I went to the site and they are showing some with ICs, I thought an IC wouldnt be needed as the air was to cool off before getting to the intake mani.

Went to the vette forum and found this:

Pro's
Well designed kit
Good performance level
Small wait time for deliver compared to other kits
Good support

Con's
No mufflers (poping noises on deceleration)
Oil pump can be loud
Stock C5 air bridge is junk under boost (buy the upgrade they now have for the kits)

Most are liking it but say that there is some lag until things get hotter then the lags is less. Not sure how that will be with us only having 6 cyls. Also most say a better oil pump is needed. Id still like to see one on a 370Z.

the guys with 350z's that i know with the kit say the biggest worry was the oil pump failures. something about lack of any indication if the pump stops/instant destruction.

If you have a fitting with a oil pressure guage before the turbo but after the pump you will know how its performing.... I wouldnt worry about that at all....

You wouldn't even need a gauge you would just need a idiot light. If the light is on stop... If the light is off the pump is working.

Road Race Engineering did an STS setup on a 4th Gen Eclipse GT, heres a link to the vid, this car smokes some cars you wouldnt expect it to....

There is a real good shot of the turbo setup a few seconds in.

Do you think the long oil line run would be beneficial to the oil temperature issue our car has?
