Greddy TT
 

Anyone know anything about the Greddy TT? I have an offer to get one at a very discounted price by a shop here locally.

I would get it, it's what Forged Performance is using on their track car. The 20g is a great turbo and Greddy has been in the game for some time now so they know what's up. It's said to be good to 800+hp so it's got good range !

The kit looks great, it was featured in last months "D-Sport". But you really need to ask yourself if your car is ready... Do you have a good oil cooler? Even if you do it will probably need to be moved to accomodate the intercooler. Is your clutch ready for the extra work? Can the stock engine really handle being daily driven with a TT for the next 5 years or does it need rebuilding first?
All I'm saying is don't jump the gun, there is a lot to prepare for before going into dangerous, uncharted territory.

I dont know the exact price but I think they are hinting at 5K installed. Im going to talk to the store owner tomorrow and get all the low down. I will have to let them do some decals and probably do a show or two and some pics. I think they are say 450 @just 6.5 psi. up to 800 hp. I want 500 to the wheels if I do it.

No different than the other TTs on here by GTM and Stillen. Im sure they will do an oil cooler if not I can make them do one.

Im hoping 500 hp is not too much for the 7AT but if so then I will bump it down to 450. If I do this.

Will the 20G give me a lot of turbo lag or is it more low end turbo?

Well if your engine explodes make a nice thread and let us know K?

6.5 psi is a pretty low psi for 450hp so Im thinking it wouldnt be too bad, plus I dont keep cars for 5 yrs. If I do this I am going to try and get a low $$$ amount, dont really know the price as yet plus I will ned a LSD too.

The VHR will not explode at 6.5psi and 450whp, the carb legal superchargers from Stillen and GTM are boosting 8. There are a few TT'ed G37's doing 500+ daily driven and going strong. I think its a great deal Steve, as far as lag is concerned, Twin Turbos generally suffer much much less lag than a single turbo, and the 20G is on the smaller end which means you'll build boost much lower in the RPM band than one with a larger compressor. Whats great is that if you decide to build the engine later, the kit is rated to 850whp, all thats needed to upgrade is larger injectors and a boost controller, according to the Greddy website. If i would have been here another 2 months, i'd have been all over this. The stock clutch will hold well at 450whp as I've learned from reading on the G37 forum, good oil cooler and an LSD and you'll be all set. So they said 5k for everything?

man, you get this thing installed, you'll have one of the fastest street cars in the city for sure, I think you oughta call out that Luna Performance GT-R and shyt on him for screwing up your cats haha

Except GReddy wasn't even able to accomplish this on their HR, even for the DSPORT article. They blamed it on the intake manifold "swelling" if i remember correctly.

easily remedied with an aluminum manifold, which they are currently building.

I'm dropping in this post with my flame suite on.

IMO the Greddy turbo kit should be at the bottom of the list for any 350 and 370Z owner. The 370Z is far beyond what greddy uses in their turbo packages. And please stay away from the magazines trying to make it look better than it is. A local guy just laid down 720rwhp with his G37 on the VQ block with pump gas and meth. The local guy has a GTM kit and loves it.

Please give your Z what it needs a good BB kit.

Greddy will be overpriced as well.

Greddy will probably cost about 16K installed.(I got a quote already) And I am sure you can go to some other tuners and get way more for your money...IMO.

I am with John on this one.

Keep in mind fellas that Steve would be receiving the kit for 5k, labor included in that price. The shop is affiliated with Greddy and is offering it greatly discounted for advertisement purposes, 5k for a twin turbo? i dont care what brand it is, thats a steal.

Journal Greddy turbos ftl! BB GTM turbo kit FTGDMFW!

Forged Peformance doesn't have a track 370Z. That car belongs to a client of FP. And it's not going with the GReddy kit. It's staying N/A for the time being.

Stillen doesn't make a TT kit. SC only. 500whp will probably be a bit much for the stock AT, so you might want to dial it down to the 450whp range. But, even then, it's uncharted territory and you may be buying a new trans or being one of the first to R&D some upgraded parts. One thing I have learned in this F/I world...don't play unless you can pay.

Eloquently put. *lol* Truly, on a car that has oil cooling issues, WHY would you utilize turbos that absolutely depend on oil temperatures to keep them cool and lubricated? Water cooled BB turbos are the only way to go on this car, imho...even with an oil cooler.

Ok, I think you all are failing to see the point of this thread. There is a shop, here locally in El Paso, that has received a TT kit from Greddy themselves for the purpose of advertisement, Greddy wants to get the word out. The shop is going to perform the install, parts included, for 5 grand. As I've stated before, I dont care what TT kit you buy, turbo size/efficiency, whatever, 5 grand for a turn key TT kit installed is a gawddamn steal, i dont care who you are. So, lets all be positive here and nudge Steve along to get this done instead of trying to sway his hand in the direction of another TT kit k?

Actually, it seems you are the one missing the point of this thread. Steve asked out opinions and thoughts on the GReddy kit, which is exactly what it seems everyone is giving. A lot of us 'in the know' realize that this isn't the best kit to go with due to some technical and mechanical limitations of both the kit and the 370Z. Why should we "nudge" someone into doing something based on price when it might not be the best thing for them?

If a fellow enthusiast is here trying to figure a way to do F/I on a budget, then we certainly shouldn't be nudging them towards anything...whether or not it seems a "steal" to you.

Im not sure of the exact price yet, I have to call the owner today, but it will be no more than 5K and Im hoping a good bit under. The kit does comes with a larger oil pan and I would do an oil cooler too. Aside from that if I only run 6.5 psi for 450HP are there still issues to be had that other kits wouldnt have? Now would htere be a difference for install from a 6 speed to the 7AT? Cuz I think he really wants a 6 speed but he has no takers yet.

Would I need an trans cooler too?

To answer your questions, I think we need a bit more information how you plan on driving this car. DD? Track? Weekend warrior?

Just as a DD with a 1 or 2 trip a year to the 1/4 mile track.

You responded very well to this thread. I think all 370Z owners should feel this way.

John, do you have any comments about the quality of the GTM kit? How was the fit and finish?

With a daily driver I am going to wager that you are looking for reliability. 450whp is about what I would look at doing, especially on the AT. I don't think you would need a trans cooler. I wouldn't think you would need an LSD, either. I would say, that no matter what, you are probably going to have issue with the oil temps and this is going to shorten the life of the turbos. That is one thing that concerned me enough to pass on the GReddy kit this time. Trust me, I absolutely love GReddy. Had a 600whp 350Z with GReddy 18g twins. LOVED it. But, not for the 370Z.

I have 472RWHP and I haven't been over 210F. Oil temps are not an issue with a Oil Cooler and an Oil Pan spacer.

where in TX? I've got a 6sp :stirthepot:

How much of your daily commute is at WOT?

I say no, Steve. But that's just because I'm a sissy and don't like risks.

Just tell me where is the shop and I'll send them my car tomorrow!!!

Zero..lol

5k is a steal, but you will still ned up at 10k, unless you srent planning for an oil cooler,exhaust, oil pan spacer,clutch,flywheel,EVC,maybe recirc bov's. Shitt ads up quick.
