My car is schedulled to go to GRD march 17 to start on my APS TT install if everything is in stock by then. Im also getting my JWT Clutch and flywheel installed at the same time. I also got some autometer nexus gauges to be installed to im really excited. I've heard good reviews about GRD and i thank them for answering questions i've had. Now i just got to wait and see if everything is there so i can take my car down there.

 

Congratulations, that is a smokin kit. I am truly jealous.

That is going to be a whole new animal for you.

 

We'll be up there on the 17th getting our tune adjusted..

 

Congrats, you're in good hands.

 

awesome, it's going to be sweet when it's done! They'll take care of ya....

 

Thanks i cant wait i've heard lots of good stuff about them and a few things people are complaning about but all in all the majority of people have all said they have done great work and were more than happy wen everything was done.

 

You going to be there in person on the 17th or you shipping your car?

I'll be there me and my dad are haulin it down there in an enclosed trailer so i'll be there if they get all my parts in. They said they should have everyhting there by then but im suppose to call next friday to make sure before we bring the car down but yeah i should be there. What you all got done to ur car?

 

Vortech with the stock pulley - changing to a 3.12". Also just did cat-back and high-flow cats. Originally tuned by Sharif, but Georgia is 570 miles away and GRD is 270 miles. Going to get the tune tweeked for the changes.

Don't put the JWT clutch in the car. It is a glorified stocker and will be overwhelmed by the TT setup. Trust me, you don't want to cut corners on the clutch

 

It has been proven to hold 500 wtrq and i shouldnt be putting any wheres never that so i should be fine plus there is alot of people running this clutch and flywheel with FI cars and it has been holding up good for them if this one dont last im gonna get a dual carbon exedy.

 

wrong, there is a JWT upgraded clutch that will hold 600+

 

I would love to see it proven to hold 500 WHEEL tq. That clutch is an organic material modifed stock clutch. I can tell you I was undersold on my clutch at first and a person speaking from experience, the JWT is a poor choice. I am sure you can find me examples of people running it without issue. Same as I can find cars running 500+ whp on stock blocks, doesn't mean it is wise or recommended.

To go to the other extreme, I wouldn't say you need a $3K exedy. There are hybrid single faced and 3/6 puck singles that will hold the power on the cheaper end, and a multiface ATS that is somewhere in the middle price range.

A JWT combo runs about 800 bucks + 400-600 bucks labor. That is $1300 completely wasted. If nothing more than the fact that it is organic and proned to glazing, I would look into a more capable clutch setup

 

I know that. That is not the clutch that 99% of the people refer to. Edit -I looked up specifics, it is a metalic twin disc. If one is looking for 600+ capability, they are going to look at a multiface carbon ATS or Exedy

 

Well i already have the clutch and flywheel so thats what ima be useing. it may be a waste of money in the end but then i guess i'll have learned something but i can see ur point to i just didnt have huge money wen i ordered the clutch and flywheel so this is what ima have to live with for now. Thanks for the advise tho

 

It isn't on the car yet, so sell it and put the money towards a more capable one. I have driven a JWT clutch and very much so did not like it. Engagement is right off the floor.....right off the floor

 

For those of you that have the APS TT kit what can i expect for horse power to the wheels? Im Going to be useing APS 2.5 in test pipes and HKS hi power ti dual exhaust. Just wondering what you guys think ima make at the wheels or if any of you have the same setup or close what are you guys running?

 

with the stock motor my buddy went to GRD and he makes 450whp I somewhere is the 8-9psi?? not sure about that.

 

I had the APS TT, APS Plenum, APS 2.5" TPs with my Nismo exhaust installed at GRD, tuned to 442whp@9psi and after 6 months blew my motor. I would advise you not to go over 400whp on stock internals. You may have a strong motor and be fine or you may not. Why take the chance?

APS in the last year has stated on more than a few threads, that they never let a Z leave their shop with more than 380whp on stock internals. If I were you, I would advise Tuan to tune it to no more than 400whp. Then save for internals for the next stage.

 

edit my above, he the guy runnung 450 also had meth injection,I totally agree with BrianG35C, 380-400 whp is still a hand full!! and some what safer on stock internals, some what
