Greddy Twin-Turbo In Development

nightfire

well greddy knew they had a grand slam with the 350Z TT kit so they would just assume the same for the 370Z. And yes the Z is light but I would by no means call it very light.

Exactly, since when is 3300+ lbs light?

I'm happy to see that they are going with the 20G turbos since I think even the GT28 based systems are overkill for what is essentially a 1.85 liter, three cylinder turbo system. Hell, two Mitsu EVO III 16G's (or equivalent) would probably produce crazy fast spools and not run out of breath on the high end.

Don't make me get the compressor maps!

I always thought the 20G turbos are a bit of an overkill, but we'll see what they can do with them

I agree. I think for 95% of us who drive 99% of the time on the street, the smaller hairdryers would be the way to go. Quick spool rules on the street. A nice flat curve, not the "S", is much more fun for 99% of the driving I do.

Well, it's not super-light, but it sure beats the hell out of the US muscle-cars that are competing for some of the same price range and marketshare, which are weighing in 3-500 lbs heavier than the 370Z.

I would also take a turbo over a supercharger, less stress on the engine as well.

That's not really true. They create different stresses, and it is easy to argue that driving another accessory is a lot less stressful than putting many pounds of pressure for the engine to work against between the exhaust valve and turbine. And that's not to mention the HEAT. Turbo setups run a helluva lot hotter than supercharger.

How well do the Mitsubishi 20G turbos fare?

I had a greddy 20g for my eclipses, put it on 3 different cars over 5yrs and never had a problem with it.. probably still going for all i know.. A LOT better then the multiple garetts that i went through. lots of bearing going out and a few wheels breaks with the others.. the greddy nothing but booost!! I had a T3/T4 on my GSX and was running high 12's - low 13s with a few bolts ons. then put on the greddy and droped to 12.4's with nothing more then intake,exaust, Apexi intercooler and injectors.. ohh and 23lbs of booost

Nissan GT-R Curb weight 3,814lbs(nissan site)
Mitsubishi Evo X Curb weight 3595 (i might be few lbs off)
BMW m3 e90 Coupe Unladen weight 3704 lbs (got it from bmw site)
BMW 335i Unladen weight 3571lbs (got it from bmw site)
BMW 135i Unladen - Manual Transmission 3373 lbs (got it from bmw site)
G37 S 6 speed Manual Curb weight 3,662 lbs(got it from infinity site)
Hyundai Genesis Coupe 3.8 Track 3389 lbs
Chevy Camaro SS 2SS 3849 lbs
Ford Mustang Gt 3534 lbs. (might be a little off)
(to be fair i included a two seater)
BMW z4 sDrive35i Unladen weight 3450lbs


Nissan 370z base 6speed MT Curb weight 3,232lbs
370z TOURING 6speed MT Curb weight 3,278 lbs

so when you do the math Mr Genius the 370z is lighter then all of its competitors. Its not a s2000 but its also not a go cart either or a mini so im pretty happy with the weight of the car.

by the way you should get out the dark sometimes and go to school maybe learn some math. That might be too much for you at first so lets start now. ill be teaching you simple math so u know that a 370z is much lighter then all those cars listed above.

1+1=2
2+2=4
2-2=0

i think class is over for today.


and by the way only the nismo 370z is 3300lbs the touring and the base are lighter

What are the bearings like on the Greddy? Are they journal bearings?

Wow. You are missing the entire point. Not to mention going overboard and being quite rude. This forum is pretty laid back, so grab a beer and chill.

The 370Z still isn't light, and listing a bunch of heavy cars doesn't make it light either, save for relative comparison to those cars. It's not about math, it's about weight.

Now maybe you just aren't aware of what is considered normal weight. It's fine. I've owned quite a few cars and have good points of reference. For the industry, three thousand pounds is considered a normal sized car. The majority of cars are on the big side. Which means that the Z probably finds itself closer to the average size of cars that are much larger. No one would argue that any of those cars you listed aren't heavy (except again, perhaps relative to other cars you listed). Also, no one would argue that the Corvette is light, much less VERY light as you said the Z is and the Vette is 100 lbs lighter than the Z.

Your numbers are close, but still a little low. The 370Z Touring/Manual has an actual curb weight closer to 3330 lbs. Want proof? Forged Performance weighed their car on corner scales with nearly a full tank of gas (which is how you are supposed to measure curb weight in the States) and got 3323 lbs. Top off the tank and see where she lands (hint: it's more than 3323).

Now, this thread isn't about weight. If you want to continue the discussion of the 370Z's weight, please feel free to start a new thread and PM me to take part.

As for the 20G, I had mine on a 2.3L stroker on my 97 Eclipse GSX. That thing spooled very quickly and never ran out of steam. I ran it at 21psi on 93 octane here. It's kind of conservative, but I prefer to overbuild and underrun in order to add longevity.
