Greddy Twin-Turbo In Development
 

cool

I wonder if they read the forums? If they don't, maybe they should, to gauge interest in a product before doing the R&D.

They should read the thread about what 370z owners want for forced induction.

Based on members that visit this forum, and I think this is the largest 370z fan site, 75% of the of people want a supercharger.

Maybe I'm wrong, but isn't Greddy in bankruptcy protection?

According to their site, they're out: Greddy - Founded and Driven by Racers

I don't have any hard metrics to back this up - but I've followed the FM/VQ35 scene for about 5 years now, and the greddy kit easily had the majority of the forced induction market for the g35/350z.

Looks like support for this platform is really ramping up. I'd like to see how this compares to the GTM product.

i love the 20g turbo.. had one on my GSX and ran high 11's on stock motor with that baby! ran a couple different turbo on the car and the 20g was by far the best.

Yeeaaaaahhhh... no firm is going to tell you they're hurting financially. If you buy that, then your stocks are going to plummet.

+ If I'm correct, Greddy doesn't make superchargers... :)

They have a supercharger kit for the Scion XB.

Greddy - Founded and Driven by Racers

I think they will make a turbo kit for the Z34. More power potential and their kit for the Z33 was one of the most popular kits.

+1111

I think the 370z is drawing a different target audience. I would have never bought a 350z. The 370z is lower, wider, shorter and has bigger tires, more power, more upscale interior, and is a higher priced fully optioned car yet more track oriented. The 370z is pulling Corvette buyers, Cayman buyers, 911 buyers, M3 buyers, RS4 buyers, GTR buyers. It's a different crowd. The polling numbers here suggest 75% want a supercharger kit to 25% that want a turbo kit.

Likewise, I am more impressed by a completely linear, tractable powerband from a SC kit that makes 400whp for 100k miles than I am by TT 611whp kit on a 94 octane tune that goes until it blows up. TT kits are fun to watch. Cool for someone else to own. But not for me. I don't have any Fast and Furious delusions that I am trying to live out.

I think it's great that 2 TT kits are on the market and a 3rd is coming. But, I'm trying to point out that from a simple economics standpoint that more money is to be made by the first company to get a SC kit to market and that more people should be putting their R&D dollars there.

Bobba, thanks for the correction...at any rate I think 370 owners might have a better shot with the likes of Stillen and prehaps Vortech making an SC for the car before Greddy.

That being said, I do generally agree with what Phimosis is saying - the market is much better for a SC than a TT kit especially at the prices we're seeing.

I'm actually interested to see what GReddy comes up with. I'm most likely going to get a supercharger if I ever go the F/I route, but more options on the market never hurt anyone right?

I agree 100% with what Phimosis has said in this thread though.

As much as i hate to admit this, but Phimosis is correct and hit the nail on the head with that statement. As an owner of both a modded Viper GTS & 900HP single turbo MKIV Supra... there really isn't/wasn't any import sportscar out there out recently that was a blip on my jaded radar* But this new 370, address all the faults of the more refined second gen 350's with the HR motor, improves on everything else significantly, all while being lighter and having more of everything. It newer styling along with its refinement makes it a great buy and value at the price point i've seen local dealers selling it for. Very great value* It WILL be stealing a few porsche, vette and BMW buyers... ;)

Great news that Greddy is jumping into the 370z FI fray! They had a pretty good kit for the 350z/G35 so I would expect nothing less for the 370.

I noticed a shot of Greddys new Ti-C exhaust as well...sexy:tup:

Dual 2.75" !!

The new gen Nissan motors response to well to twin turbo setups, I think this will be the FI of choice moving forward. Superchargers, frankly, just aren't that exciting on small displacement engines, and will never offer the shear power and overall performance benifits of a properly spec'ed TT setup. Of course, they will be priced lower, than TT's but that is the only benefit I see.

Huh? The only benefit is price? Simplied install and removal. Less auxiliary parts required. Simplfied tuning. Increased reliability. The list of benefits is long. If you can point me to a turbo tuner that offers CARB certification and a 3 year 36,000 mile warranty, please point me to them. I have never seen that for any other aftermarket turbo setup, so I don't expect any breakthrough for the 370z.

I would restate the argument as the only benefit that turbos have is a higher hp output.
I do want more power than stock, but I don't need 600 whp to be satisfied.

If you are located in California, there are many more considerations. You are correct, in that CARB exemption will not be earned with any TT kits in the foreseable future.

Simplified installation and less parts, typically translates into less costs, and lower price. The 3 year warranty offer by the Stillen kit in the 350Z world, is very restrictive, nearly to the point of being worthless.

In terms of reliability, they both have their pros and cons, but from our experience, TT's are just as safe as SC's when installed, tuned, and setup properly. The perception that SC's are safer, stems from the fact that you have a higher margin for error in tuning/setup.

Ask anyone that has driven a SC 350Z, and a TT 350Z back to back. I promised you if money/CARB was not a consideration, everyone would want the TT. :)

On the g35/350z, there were four superchargers available: vortech, hks, stillen, and procharger. The stillen was the only roots type. The vortech and procharger were both centrifugal units. The hks was a rotrex unit.

The stillen made great torque down low, as typical of a roots, but it gave up *way* early. I know of a stillen stage1 g35 coupe down in florida that ran high 13's in the quarter at like 101mph. My g35 runs low 13's at 104mph with boltons. The undersized roots unit used by stillen is the joke of the forced induction community in the g35/350z world.

The vortech and procharger units make much more power than the stillen. But because they are centrifugal units, they make no torque. Also, they have problems holding on to the belts using the smaller pulleys. And you want to talk about reliability? The vortech blowers have had problems with bearings lately.

On Sharif's dyno(a dyno dynamics), a bone stock VQ35DE with a vortech might put down around 340whp out of the box. The same car, with say an APS single or a Turbonetics single(the second most disparaged FI kit) will put down the same rough peak power, but will also put down close to 100wtq more than the vortech.

To demonstrate the difference in torque, many supercharger owners go for shorter gears(say 3.92's or 4.0's), to get into boost more quickly. But the turbo guys, if they do anything with gears, always go to taller gears(3.54's to 3.3's for the manual guys).

And before you buy into any kind of warranty offered by Stillen, check around the g/z world to see how well that warranty worked out. I know of a guy in kentucky that slung a rod; he had his car trucked down to Atlanta and Sharif performed the post-mortem on the engine. He also did all of the footwork on the warranty. That was a couple of years ago, and I'm not sure the car's owner got everything worked out on the warranty. Also, that warranty was only offered on the Stage 2 version of Stillen's kit. If you wanted a Stage 1 or 3, you didn't have that option.

I'm not swapping pullies and I'm not replacing a belt every week.

Put me down for a turbo kit.

I do plan to purchase one in the very near future.

TT for me when it's available.

How will the 2.75" GReddy exhaust compare to any other 3" after-market exhaust? Mainly for the guys who really want to go FI, would this be a good route to go? I really want to see what the difference will be.

dual 2.5" is typically good for up to 500whp. >500whp it becomes a bottleneck from what I have heard. If your shooting for 500-600whp 2.75" should be cool. 3" for overkill or 600whp+

From the Greddy link: That, I'd have to see to believe. I can't imagine a TT kit that's truly a simple bolt-on :)

+1. Anything that requires touching the manifolds is hard to consider "bolt-on".

Im hoping this kit will be more aggressively priced than other tuners TT kits b/c of Greddys size/volume. If its a quality kit and $1-2K cheaper than competitors im all in!

+2 might consider the GReddy TT kit :D

A Greddy true dual 2.75 incher would be ideal for FI. Easily will handle 650-750whp if needed....same type of designs we've used on the 350Z TT.

A 2.5 inch true dual, while not optimal, would be perfectly happy in the 450-500whp range, but more power will always be available with a slightly larger exhaust, at just about any boost level.

Thanks alot, could of not put it in better words !:ughdance:

So are you saying that if I had a 2.5" (outer diameter) exhaust installed on my car, it will be more than adequate up to 450 whp? In other words, I would see no benefit of upgrading to a bigger exhaust diameter up to that power level?

If I drift away from a S/C, I would like a pair of very small turbos.

Yes. I'm getting 470WHp with no problem on my 2.25" Fast Intentions w/test pipes. 2.5"+ would be better but the cost is more noise.

Good to know.

If noise is the issue you're wanting to get away from there is always an electronic cutout. I ran this on my turbo RSX with a quiet exhaust and picked up great gains, but of course it was extra HP/TQ/noise at the flip of a switch.

Welcome to DMH Performance!

Bolt on is anything that doesn't require cracking the engine open. So yes, turbo kits are bolt-ons.

Can anyone say blown motor?
lol

I wouldnt say that yet, the newer engines are proving quite stout.

It's bound to happen to someone tho... lol
Hope it's not me! :wtf2:

Oh of course, but these new engines are leaps and bounds ahead of the old DE's as far as that goes. imo anyway...
