2fast4theLaw likely had an auto. Those sound like Auto numbers to me... In fact, I had an auto as well and that's what I got until I put 3.73's in the rear end where I lost about 1-2 MPG. All my friends and I get/got beyond 30 on the freeway with the m6. The BIG difference between the 4L60E (auto) and the T56 (manual) is that the auto had a crappy overdrive after 3rd whereas the T56 has 2 overdrive gears (one for street, one for freeway) and at any time, the car can cruise at 1500RPM. 70MPH in 6th gear on the freeway is 1700RPM.

The LS1 is already a very efficient motor... Giving it better gearing like that is only going to help its case. The auto, however was a 3 speed + over drive. And that trans was terrible for fuel economy.

LS1 Gas Mileage - LS1TECH <-- Totally unbiased MPG results. Some really low (from VERY modded cars) and some exceeding my expectations.

What shows up on paper isn't always true. GM under rated the LS1 F-Bodies to sell more Corvettes. So are you saying that just because it's on paper, the F-Bodies were 325HP instead of 350? Because a dyno would say otherwise.

And yes, that saying is old. But I don't feel it's outdated. Technology only gets better, but the truth behind the saying is still what it is. A current day Big block is still FAR better than a current day small liter motor. ANYTHING you do to the smaller motor, you can do to the bigger motor and the results are only escalated, but not changed.

Crash, I wasn't saying that paper is truth set in stone, I was merely getting some numbers to show that the Z and the LS1 have similar specs as far as fuel consumption. And all the higher numbers for the LS1 seem to have come from modded cars and not stock cars. Anyway, this disscussion about fuel is moot too me as I said before - it's a sports car.

Speaking of moot, this thread has gotten completely off topic...

You may have had a Corvette, but it wasn't a 97 or newer if yours didn't handle well. The C4 Vettes handled OK, but I'd agree the Zs handle better. But the C5's were meant to be tracked straight from the factory. The handling and braking on the Z06 was top-notch. The C6 Z06 has even better handling and is arguably one of the best track cars in production.

I made the unfortunate mistake of buying a 2002 C5 corvette with an automatic trans. It was the worse car I ever owned! The front nose is so long that the car always felt awkward and nose heavy to me. I kept it one year and sold it off. It was plagued with electrical problems and rattled like a Model T.

I think its great that you love the vette, you can have them! I can't knock a Z06 as I have never driven one, I would however expect much from it as it carries a very heavy price tag!

Bottom line, I love my 370Z and I feel its by far the best performing, best handling, and best looking car out there for the money. If you dont agree, than I really question why you are even here on this site! There are many Corvette forums out there for all you vette nut huggers!

this thread is about a rear-mounted turbo setup in the 370z fellas...not GM/corvettes versus blah blah. Take this discussion elsewhere on the forum.

LOL! Sorry, didn't mean to hijack the thread...

Back on point, the STS kit is kind of expensive for what you're getting, but the biggest benefit to it is that you don't have to modify the crap out of your car to make it work. Most turbo systems require cutting and shaving and bending. They're really just not easy to install and if you remove them at any point, you have a lot of under-body work that needs to be done to seal up what's been modified.

With the STS kit, it's pretty straight forward. Since they've realized they do need an intercooler, it seems they're including it with the kit now. But the good news is that the intercooler doesn't have to be big leaving a LOT of room for expansion later (or getting a bigger intercooler and upping the boost).

I've thought about doing a staged STS kit so that there's no boost lag.

Any thoughts?
