Greddy vs. GTM TT Kit
I know there is obviously going to be some competition, and some die-hard supporters of either, so please stick to the facts without the head-bashing.
Which one is better? Which one will last longer? Which one has a more OEM type feel to it? Things I don't like about Greddy: They seem to skimp. Aluminum, using oil without water cooling, FOAM!? air-filters. Things that make me unsure of the GTM: It is cheaper...is this because there is less profit margin, or are some of the components made in-house, or what? |
Personally I don't think we've seen enough examples run long term on the streets to make a call. You're also forgetting AAM's turbo kit but that will require an inhouse install, Fusz's Z has it and I believe he's pretty happy with it. I think GTM's success with bullitt's stroker build will show how serious and skilled GTM is.
|
AAM says something about not re-routing lines off the block and no modification thereof, does the GTM require this?
Also I have read about giving up the windshield washer resivor. Does the GTM give this up? |
who really uses windshield washer fluid anyway?

if you live in a desert you do :D

To OP, yeah, unfortunately not much is known on pro's and con's of each, as there are few cars with either kit at the moment. Really, I'd say compare and contrast the few dynos there are and cost for each and go from there. Also, the few odds and ends you don't like that come with either kit can be swapped out (e.g., filters). I'm 95% certain that the greddy kit does not come with a reflash, so that's one other thing to consider, whereas the GTM kit does, I believe. |
I have been installing the GTM stage 2 twin turbo kit in my garage on my car for about the last week. I should have the car done by the end of this weekend, and i intend to do a full review on it. I will give all the info from the pros and cons, to how the car feels, and the customer service that I was givin when I ran into problems and had to call Sam. I will tell you this I don't know about other kits but with the GTM I had to drill 2 holes and tap them in my passanger head. This wasn't hard at all SAM sends a template with his kits for this and my god it is idiot proof. Also you have to drill the Upper oil pan for the return lines for the turbo. Like I said by the end of the weekend I will have up a full review thread and give my thoughts and opinions on this kit and that should help you choose which one you want.

TONER, are you planning on dyno testing after all is said and done? I know the last person who did the at home install ran a super conservative tune until he got on the dyno. What power goals are you shooting for??

Does the Greddy offer a tune out of the box??? |

-GTM kit comes with Pre-Bent Stainless Steel Heat Shields Greddy does not offer any heat shields over the manifold -GTM Bar and Plate Core Intercooler vs Greddy tube and fin core (bar and plate is proven to be more efficient ) -GTM Ball Bering water and oil cooled Garret turbo VS Greddy journal bushing type turbo and oil cooled only (ball bearing turbos spool faster,more efficient,have a much longer life span and for the 370z oil temp issues going with water cooled turbo is no brainer. -GTM kit does come with tial 50mm blow off valves VS Greddy No blow off valves are supplied. -GTM kit is complete with fuel and engine management VS Greddy does not come with neither (have to by separate) -GTM engine managemen is plug and play (via flash ) Greddy is piggy back system required cutting splicing engine harness. -GTM kit has a lot of room to grow (6 different turbo stages 9 different a/r ) VS GReddy has one turbo option only available. -GTM kit cheaper and has better value, you get more for what you pay for VS Greddy -GTM offers 2 different couplers colors VS Greddy only one -GTM offers k&n filter VS Greddy foam filters Sam |

For those of you worried about the windshield washer reservoir, you can buy an aftermarket reservoir that mounts in the trunk. GTM sells the kit for something like $100.

Op asked for the differance and which one was better. Sam came in and cleared the differances up. If greddy gave a damn why didn't they post, or is it because they aren't on the forums listening to what there customers want or need. I am not trying to attack you and sorry if it seems that way but that seemed like a very unneeded comment Frank |

Frank The tune that you have is the final tune we have a proven formula that we use and it does work spot on. it is always a good idea to verify the install before start enjoying the car. you need to make sure the a/f and the boost is where is suppose to be and that a common procedure in any force induction install . Keep up the good work . Sam |

And to Sam, not taking anything from your business, but every post you make seems to embellish the fact that everything you guys make blows the competition away, I seem to remember a particular oil cooler problem that keeps recurring.... Anywho, the Greddy kit contains just as many quality parts, its unfortunate for them that they dont have anyone here to defend their setup.:ugh2: |
Greddy's kit contains much less parts that are lower in quality and none of the great support and service that GTM's kit comes with. In that case, then yes GTM's kit is definitely superior.

Can't wait to get our GTM kit in!!!!
:tup: Be on the look out for pics and blog write up. |

I think the OP asked for the difference's and Sam was happy to give them. Whats the problem again? End. |
:iagree:
|
Ok so it's well discussed that thus far GTM's TT kit comes off as the best due to the quality, their customer service, and the fact that it comes in kit form where AAM does not.
So all I have left to say to Sam is how about you guys figure out that S/C kit because I really want to match it with LTH's. I have faith that in time GTM will figure it out. Sam I sent you a PM about the stroker, when you get a chance bud.... |
I still want to know about the wavy hp curve on all the dyno's I have seen.

Bump
Stage 2 GTM TT kit ordered and eagerly waiting arrival!!! |
