-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

Just a little clarification

Greddy turbo kit is a tuner kit meaning that it does not come with neither fuel system,engine management and not even blow off valves so it needs to be compared to our SET-UP KIT set up which has three different stages vs one option from Greddy and also much cheaper with better components .

GTM Motorsports*::*FORCED INDUCTION*::*GTM-370Z-(SET-UP) TWIN TURBO KIT


Our TURN KEY kit is the only compete twin turbo kit on the market that comes with every thing you need to do the install and has four different stages .

GTM Motorsports*::*FORCED INDUCTION*::*GTM 370Z (TURN KEY) TWIN TURBO KIT


Then we have our TUNER KIT that offers 6 different stages from 500 hp to 1200 hp .

GTM Motorsports*::*FORCED INDUCTION*::*GTM-370Z-(TUNER) TWIN TURBO KIT


Hope this help
Sam

I can help with that if you don't mind. First, oil cooler(I went with the GTM competiotn one, works great)

Second I recomend you getting a exhaust I went with the HKS one and it has a Stock sound to it which is what I wanted. It starts to wake up in the higher RPMS.

Next I would sugest test pipes or hi-flow cats. This is not a must but it will help the turbo breath better.

Also your going to need a boost controller. I went with the EVC-S since it does what I need and I also didn't need all the extra stuff that came with the EVC-6, but that is your decission since you might be going a different route.

Last some type of guage system I don't think it is a dire rush since they can verify everything on the dyno but eventully I recomend it. I didn't want guages all over my car so right now I am saving up to get the Blitz system that will display everything through my gps. If you don't have that then maybe if you want to hide them you can put them in your center cubby hole. Just a few Ideas but this is what I recomend ou go with.
Hope this helps
