You say that you searched, but then you ask if anyone on this board has the greddy kit??.....

+1 ^^

 

I know your new so I will be the first to help.

There are different kits out there. Some people like different things about each of them it just really depends on what you want and if your willing to search for the characteristics of the different kits.

You cannot go wrong with the greddy kit IMO. I would say get it and make sure you get a good installer for it as well. The other thing a Turbo kit owner would suggest to get with it is ----

New Clutch - If you plan to exceed 400 whp which is right around the power you will make with any set of twins at stock psi then a new high performance clutch is in order. ACT/JWT are the ones I hear from most members when getting a nice new GOOD clutch.

Gauges - Boost, water temp, exhaust temp, oil temp etc... You can monitor almost anything. You will also need some other things just for the gauges like a control unit for the gauges to link to and some sensors, not to sure on this subject but from what I hear you shouldn't be spending more then 1k for the gauges setup.

Fuel return/injectors - Greddy kit comes with 440cc injectors but may want to consider an after market Fuel return system with bigger injectors. AAM pops up alot when I hear of fuel return for the Z

EMS (Engine Management System) - The greddy kit comes with one but may want to consider getting a different one. Utec is one of the most popular EMS's for the Z ($800-$900 new.) Also the HKS F-con v pro is a very pricey but if you want the best in quality that’s up in there, around $1,400 new

oh and some wider tires....


If you want to make it a little easier then there is the APS TT or ST kit that comes pretty much complete out of the box compared to the other kits. The kit is somewhere around 7k new for the TT setup and like 5k or so for the ST new. The kit's both come with Intercooler/Fuel Return/larger injectors over stock/Oil pan/EMS.... BUT!!! you have to have an authorized APS dealer install it which there aren't many around. You will have to ask where they're located because I'm not sure.

Makes the shopping around a little less harder...

Hope this helps.....

 

the greddy kit is a great kit, but u need to tune.
like sharif says its like a time boom
ask sharif at forgedinternals.com

 

I have had teh ST and I loved it a lot, but it melted two ac lines, is one of the reasons, I got rid of it. The car is an absolute blast to drive with the greddy twins installed now, but as Xx safaka indicated, gauges, clutch (don't forget a lightweight flywheel), ems (I run UTEC), fuel return, larger injectors, and wider tires are a great starting point. Don't forget some type of Boost control and a great tune. I have now used both electronic and manual boost controllers, and I can say with a great amount of confidence that electronic boost controllers are far superior and worth their weight in gold.

The greddy kit is a great kit that can grow with you once you get used to the power. Look at Alberto, stock displacement built motor and from what I can gather, the out of the box greddy kit with above mentioned supporting mods making around 578 whp on 15 psi. My car feels like an absolute monster with only 7 psi and I couldn't imagine 15 psi, it has to be absolutely insane.

 

I hate you.... Your talking about how fun and what a blast it is to drive a Greddy TT Z and now I'm all sad because I don't have TT's.....

I've never been in a TT or ST Z yet and I really want to feel the beast of the TT Z.... Please god give me ONE TT z here in Tucson to get a ride in!

 

its ok... feels a little better than my Nismo CAI and Nismo Exhaust...

 

Is there any advantages or disadvantages of going 550cc injector or 650cc injectors rather than the 440cc injectors the kit comes with?
(keep in mind stock block with stage 2 fuel return and Utec)

 

The advantage is you'll have room to grow with the 550's or 650's and also you won't be running them past 80% duty cycle while running 400-440whp on the stock block.

 

I got flamed for not searching it when I first came here...



I know its a pain to search, because of the volume of the results. But all in all, there is usually related info that you didn't think you'd need, so youre better off. Plus, searching instead of starting new threads limits the volume and makes it easier to search.

 

I hate my Greddy kit, 580whp sucks....

 

lol.. yeah right.. the only thing it must suck is on gas mileage

but i can live with that

 

What are your HP goals? As long as you run the Return Fuel System and the UTEC you have all of the tools to back off the injectors off boost. But if you are never going to use the flow capacity of the injectors, there is no reason to go larger.

I see you finally got you sponsorship to work here. Glad to see you on the boards.

Here is you a little shout out for being a great guy and helping me so much when I had my TN kit. I bought everything but my twins from him and would love to do business with him again.

 

I guess that I will have to recant my last statement, of the TT being great.

Doug don't forget the grounding kit and the decals. These mods would definately scorch our TT's.

Stock internals Goal = 370-400
Built Goal later = 500-550
