Wow that looks like a great setup....but damn its expensive...then again so is the APS......dunno what to do, how is the greddy tt??

 

The APS TT is the most complete and safest out of the box system. It comes with a shield crank angle wire and fuel return solution. Also they aren't many unichip tuners (the piggy system APS uses) so you won't see as many people re-tuning and blowing up their motors like with the greddy. The APS comes with a safe tune already.

If you go greddy will you need to buy the extras to make it a complete and safe kit. You will need the fuel return solution, a walboro 255 fuel pump, ignition harness to adjust timing through the emange, a pressure sensor harness to MAP tune (better than MAF tuning), a BOV, and a shielded crank angle wire. Read the thread below about the fuel system and map tuning for the greddy.

You first need to ask your self what are you hp goals. If you want more than 450rhwp and you don't have an authorized APS tuner in your area you won't be able to achieve it. The tune that comes out of the box is good for about 425rhwp give or take a little. Also, The APS and GReddy will be fine for 500-600 horsepower, if you go over 650rwhp with the APS expect to need to swap out turbo's and the GReddy's at 700rwhp+.

I don't know much anything about the other TT's.

 

Where did you get 425whp out of the box for APS? Everybody I've heard about with the APS kit was getting 380-400 the most out of the box. I think most people were around 380 with a stock motor and no other mods.

 

Go here and scroll down to the first dyno. This was done with out exhaust or test pipes

The above dyno chart demonstrates the power at the wheels of the Infiniti G35 fitted with the APS Intercooled Twin Turbo system running on 93 Octane (R+M)/2 fuel - utilizing the APS 93 Octane engine management strategy.


If you add the exhaust and test pipe you can easily get 15-20rhwp more.

 

APS all the way..... it's not very close at all in terms of quality and results compared to ANY other kit..

 

According to APS dealers/installers in So.Cal, out of the box its 330-rwhp on 91 octane on stock Z, with APS exhaust up to 370-rwhp, add another 20hp with 93 octane. SSR TT kits are getting 402rwhp with 91 octane with only 6.5lb boost.

 

APS all the way! Greddy is tempting because its 2k less but in the long run if add everything up you will need to make it a safe kit you will be at the same price as the APS. Go APS TT if you can or APS ST or for less go Vortech!!!

 

The APS website shows a dyno for 91 gas and no exhaust at 380rwhp.

 

True. However the dyno#'s here in states are showing a different result.

 

470 WHP @ 10.5 psi - G35 TT what a hoot

 

oh lord...

 

????

 

So either way im looking at around 8-10g for the setup and installation no matter what kit i go with??
