First off Vortech puts out superchargers not Turbos. And to answer your question you say 137whp added at 10psi. The Greddy kit made 90whp at 5-6psi. (.4 Bar) So if someone were to run 10psi on the same kit it would equate out to ~200whp added. The turbos are 18G, so they aren't really small, definitely good up to and probably above 18psi. These numbers are just rumors at this time. Once tuning is complete then we can talk real results.

Also if the Greddy Kit does end up being $7k, then the benefits of a TT setup had better be far better than a single turbo kit.

 

Actually it is a turbo on a stick. I do agree that performance needs to be higher for two turbos. Either way, it iss a waiting game.

 

Incorrect, Vortec is a centrifigul supercharger. Supercharger denotes that the unit is crank driven, turbocharger denotes exhaust driven. Supercharger equals parasitic drag and additional stress on the crankshaft snout. Turbocharger equals entirely more efficient.

Regarding the Vortec out of the box on a Civic Si versus a GReddy turbo kit on the same car. Although the Vortec has a higher peak HP (and at near redline), the GReddy turbo kit has higher average HP across the ENTIRE RPM range and makes for a more powerful car!

Now, add a boost controller and some additional fuel and wham, no comparison. I will take the GReddy kit over the Vortec 100% of the time. Not that Vortec isn't a nice product, just that I would take a turbocharger over a supercharger every time. More volumetric efficiency. More upgradeable.

I don't quite understand the mis-matching comment. Maybe you could expand on that for us. The GReddy kits are among the best engineered pieces in the world. That's why it takes them forever and a day to introduce them for sale.

As far as size goes, GReddy's TD05H-18G turbochargers are the direct result of their famous Lancer Project. Just one of those turbos on either a 4G63 (Eclipse/Talon turbo) or a B-series (Civic Si/Integra) can support up to 450HP, which is beyond what the engine can handle with building it.

The Power Enterprise turbo kit that we are also selling will have more power out of the box. But it probably will not pass emissions at all. And it is having to be re-engineered to work on North American vehicles (i.e. left hand drive). Will keep everyone posted.

When will the first kit be available? Who is Power Enterprise? I never heard of them.

 

What sick perosn would pay $10,000 for an extra 90hp.i have a 2002 vette with a vortech supercharger and borred out to a 383, and have 550hp to the rear wheels with 630 in torque and only paid $8000.
i heard from the manager in sales form greddy and he told me that kit wont come out. the whole engine has to be taken out just to instal the kit

 

There's no way that GReddy would put so much effort and expense into developing a Turbo kit for the Z that they would just abandon it shortly before release. That would be an extremely stupid move considering current interest by the public. As for the fact that the engine has to be taken out...well...duh...thats a give-in for any small engine compartment.

 

A person who owns an OBD3 car with a direct fire ignition that currently has no way of retarding the timing to get any more reliable power than that out of it for now. Once the ECU is cracked, watch out.

Do you even have a 350Z? Do you know anything about these cars? If so, I would guess it is pretty stock. I am interested in hearing about it.

Shawn @ Street Sports

 

it's just a matter of how much the stock motor can handle. these turbos are good for well over 600rwhp. boost is just kept down because the stock internals won't be able to handle too much power.

 

I happened to be on a three call with Shawn from Street Sports when he called Greddy.They are coming out with the kit. The bad news is it probably won't be available till the end of the year.

 

Shawn,

Know of any work being done for the G35c?

Matt

 

Omg so many whiners..

You realize that 90whp for 5.8 psi is ALOT. It does NOT mean that this is the maximum that the turbos can handle.. only a safe "starting" amount that Gredy is playing with.

Which means that with a few small changes you will probably be able to run it safely at 8-10psi for a total of 150 extra RWHP or so.
And I'm sure those who like to push things to the limit will be able to run it at double that... so the numbers are actually quite strong.

With regards to price, we'll just have to wait and see. Obviously 7-10k for a bolt-on is a ton, and I wouldn't buy it at that price... but there's no point in guessing.

Shawn, thank you for taking the time and effort to keep us posted. Don't mind all the negative commentary from the peanut gallery

 

actually 10k installed is a pretty decent price if you put it into perspective. you add the cost of the car, and you have a 400 hp car for 40k. there's no other car out there that'll get you 400hp for that price.

 

Well, Greddy and others better do their homework because they are going to lose a lot of business if it is that high.

 

Well not that I'm a fan of the car, but for the money a SC Cobra will get you 400HP and beyond for around 40K

 

good point. just as a reference, when i was thinking of an e36 ///M3 i was looking for more hp than Dinan superchargers offered, so i checked out the Active Autowerke kit. Mitsubishi turbo, plus basic kit (very basic) and the cost was more the $10k. Also, that kit runs at ~400hp(crank) at 9 psi, but doesn't have the worlds greatest reliability rating.......soooooo, if GReddys is at 5.8 psi (very VERY conservative) , with 90 to tha wheels (with room to go) for $7k....and history of reliablity(underestimated when speculating bout turbos) .... id say its a deal. C'mon guys, we're not in a $4k civic here looking at a $7k turbo...., if it brings the power it promised, its a deal....

my $0.02

 

I agree. There's no point in whining about price before what we see what it actually is.

GReddy is not a fly-by-night company. I'm sure they realize for their product to be successful, it has to have acceptable power gains without pricing it out of reach of the masses.

I would hope they could do the kit for under $8K installed with 100+ rwhp gain. But I will happily wait and see what they can come up with. If it doesn't come out until year end, that just gives me more time to save money to buy myself a "Xmas gift".

 

Shawn,
Can you clarify a few things. First of all, It ticks me off when people come on here and start spouting off and making remarks that are just guesses, and acting like facts.

"SUPERMAN350Z" said in a post earlier in this thread that the "Entire engine would have to be removed to install the greddy TT kit".......I find this very hard to believe. That would cost so much money for anyone getting this installed.

Can you comment on this remark? Pure BS I assume?

Secondly, with any turbo kit, it has to be hooked up to the exhaust. Since I have never had a turbo, where does the turbo piping hook up to the exhaust? At the headers, before the cats, or after the cats? Can you use ANY exhaust with the Greddy kit, or is it required to use theirs?

In other words, does the Greddy Exhaust have a "Flange" valve that allows you to hook the exhaust to the turbines?

 

Although I do not know what the price will actually be, I would plan on it being around 10K. The reason I say this is because the upgrade kit for the 300ZX which is based on TD05-16G turbos with SUS manifolds and 2 Type S wastegates is $6454.44. The kit for the 350Z will be based on TD05-18G turbos. If they use Type R wastegates instead of Type S wastegates in the final production kit, they are $200 extra each which is another $400 added to the kit. If they use an eManage with the kit, that is another $379. They are planning on including new injectors with the kit which should be 6x say $136.36 (the price of GReddy fuel injectors) which is $818.16. Now I do know that they will not use their own injectors, as they do not have the proper side entry injectors. This means that they have to purchase them elsewhere (perhaps Nismo??) which may or may not drive up the price. Now, if it ends up cheaper then great, everybody will be happy. But what you should do is plan for the worst, and hope for the best.

As far as losing business? No way. In case you haven't dealt with GReddy much, let me tell you. I started out importing their products in 1993. Two years later, in 1995, they opened up their U.S. office. I was a dealer right off the bat, obviously. In all that time, I have only been able to get kits I ordered about half of the time. The other half of the time, I have had to backorder them. For every person that does not want to pay that much for a turbo kit, means every person that does won't have to wait as long to get theirs. In either case, GReddy will do their best to keep up with demand. So they won't lose any business, trust me.

And in this whole thing, you have forgotten one very important aspect to this. If GReddy does in fact get this kit CARB certified, they will double their sales. Because who in the world is going to continually pay the labor to take the kit on and off to pass emissions all the time? No one. So from a marketing standpoint, GReddy can't lose.

350z_taquito:

Excellent point! If you really stop to think about it, the 'value' of a $40K 350Z is incredible. For $40K, you can also have 19" forged wheels and big brakes (whether buying a track model or a non-track model and making your own choice of brake kit and wheel brand and style). The car already has a good suspension, although you can easily bolt-in a coilover upgrade. You should already have an exhaust and such if you did the turbo kit. I mean for $40K, you would basically have a CARB legal, completely streetable (starts easy, good idle, decent gas mileage), reliable car, that will last, keep resale value (but why would you ever sell?), and be very good looking.

I would say it would be such a good overall package that you might be hard pressed to find a better overall package AT ANY PRICE! Think about it, what other car would you choose and why? Anybody want to answer that legitimately? You want to say Ferrari? Fine, but you better answer why, and it better be legit. If not, I'll slam ya! But in any case, everyone should get the point here.

Shawn @ Street Sports

 

I will do my best to get these answers, but as you have already determined, it is much better to be accurate, even if that means less information. Unfortunately, there are some 'shops' out there (whether they are legit or not, they still make everyone here think they are), trying to sound like experts. They are trying to be first with the information, I guess for brownie points. I could have come on here months ago with the information that GReddy had a kit coming by letting Monkey Man post it, but I decided to wait until I had some CONFIRMED information. Monkey Man and I have been suckered ourselves. We have read things on this forum, become either exhilerated or fired up about what we read, called the manufacturer about it, just to find out it was incorrect. Then we feel like idiots for believing it, figuring that with the friends in the industry that we have, we should have known better. As far as anything we say on this forum, it is fact unless we otherwise make known.

As far as the engine having to come out. That seems VERY unlikely to me. Could be true, but I doubt it very seriously. I will contact friends of mine in the R&D department at GReddy and ask.

As far as where to hook up to the exhaust system. The downpipe (piping that comes from the turbo and generally will terminate at the same point as the header piping), will probably connect to the catalytic converter inlet. Since GReddy is trying to make this kit CARB legal, the converters will have to stay.

As far as the exhaust system, since the turbo kit will be engineered to use the existing catalytic converters, and their positioning will be relatively the same, you should be able to use any cat-back system from any manufacturer without any problem.

CluelessZ, thanks for making this post. I'm sure there are others out there with the same questions as you, but maybe felt like they would be ridiculed for not knowing. Of course, anyone doing that was previously at a point in their life when they knew just as little. Maybe they just forgot. Hope this has helped you (and others). I hope to keep this thread going, it seems to be becoming one of the more 'informative' ones on the forum. If anyone has any other questions, please don't hesitate to post them, and DO NOT WORRY about what anyone else thinks of your knowledge level, because when you are done, you may end up with similar knowledge yourself!
