Alright guys, so I found a used Greddy Twin Turbo kit that comes with the complete kit for me to bolt on and then some, which I will list. I just wanted to know how ya'll felt about a used Greddy TT Kit that has 10,000 miles plus on it. I plan on putting this onto my 03 Z Track model with 37xxx miles on it. I'm a little sketchy about it, but just would like to get some more views.

Greddy TT Kit
-Complete kit with turbo's, oil lines' pipping, greddy intercooler, turbo manifold, injectors, etc. (Everything I need to get it installed and running)
-HKS BOV
-SGP 3" Downpipe
-VRT Open Dumps
-UPGRADED Greddy Ultimate Management
-Clutch Masters Stage 3 Clutch (200 miles)

So what do you guys think? Don't plan on running crazy boost, 5-7 psi maybe.

 

Is it a Tuner kit?

 

It is the Tuner Kit, along with the Greddy Intercooler Kit. It came directly off his Z.

 

The tuner kit has 20g turbos which can support close to 800hp... The biggest thing to look for is that the turbo impeller has no shaft play, isn't leaking oil or anything, and the pipes aren't cracked. How much boost was the owner running?

 

How much do you think I can do on the stock block? I've been reading through out the forums the past few weeks and have learned that the weakest part of the VQ motors are the connecting rods. Anything over 450+ HP is to much, correct? And also it is vitally important that you have a good tune ran with your kit, or else you have the chance of blowing it up. Did I get most of it in a nut shell? lol

He ran only 5 psi. And alright so when I go up there and look at the turbo's look for if it has shaft play? Anything else I should be aware about?

 

The emanage is crap get uprev for your tune

Look for shaft play, cracked pipes.

Couplers are cheap if they are worn or clamps are worn you can replace for cheap and you should.

stock block 400 wTQ is considered the norm for the threshold of the rods.

check the turbos for shaftplay, look for leaks or bad seals, find out if they have been rebuilt/when.


biggest concerns are the turbo's and the tune. if the turbo's are good then make sure you get a good tune and you will have a "safe" FI setup.

5-8 psi is all about the same reliability on a stock block with a good tune the tune is the most important aspect on a stock block.

ALSO I didnt see any fuel components on your list. Are you getting injectors? fuel pump? return fuel system? fuel rails?

whether or not he is throwing them in you will need 1 step colder spark plugs I suggest getting new ones not reusing his.

 

What he said

 

Alright will look into the uprev ecu.

And as for fuel situation; I'm just getting injectors, I'll probably end up buying a walbro fuel pump and such. Also when I get my turbo installed by my shop, they will be putting one step colder NGK spark plugs, got the install and everything all quoted for.

Appreciate the input guys, well hopefully everything looks good with the kit, and I don't see any shaft play! Will let you guys know!

 

buy my greddy setup

 

walbro 255 with DW600cc injectors, fuel rail and a RFS and you should be sitting pretty.

You "can get by" with just the 255 pump but you will have a much safer more relaible setup with the RFS

does he have a oil pan spacer or the bigger oil pan??

 

Even if the turbos 'Seem' fine I would send them to greddy for testing. Makes sense to be sure they are fine before installing them. Money well spent in my book!

Good luck..... Properly set up greddy kit is amazing!!!

 

Tuners come with the Greddy oil pan.

 

+1 on the tune and fuel system, a good conservative with low AFRs will go a long ways on stock block

 

RFS is overkill for what u are doing and also bigger oil pan or spacer for oil pan, stock one will be just fine for some low boost..get injectors and a pump and a good tune..

but at the end of the day id buy a new kit and not a used..

8psi would be just fine with a good tune and the emanage ultimate will be just fine for what u are looking for...really dont know why people are always trying to tell people to change what they have, the tune is only as good as the tuner...If u can find a good tuner to tune the emanage that uses it then it will be more than fine for u...

 

Alright well I'm looking at Jotech in Plano, TX to do my tuning, they seem to be quite stout and stand by there work. So then as for fuel, all I should need is bigger injectors and fuel pump, and I should be good? Just want to double check and be safe AS I can.

 

the OP clearly stated he wanted to be as safe as possible. Doing that involves slight overkill. Sure you can cut corners and save a buck or two but then if you have something fail, or if you dont have the knowledge/experience to prevent a failure by recognizing the signs then it will cost you 2x as much then just doing slight overkill in the beginning.

 

I dont really know your are check in your regional forums but I do know Jtran in TX is a great shop as well. But I dont know what kinda distance that is for you.

 

Kenny and Tony @ Jotech are good guys and have a good sized shop and crew. Not sure if they are tuning UPREV though. I've seen a few cars with OK tags there too. Jtran is in houston so that would be more of a drive for your, but i've heard good things.

 

Yeah I just talked to them today, and they said they should have no problems. Tony down there recommends I get a boost controller, and many of you stated, bigger injectors, and fuel pump to be on the safe side. So I'll defiantly be picking them up! BETTER SAFE THEN SORRY!

Also just a question, I was thinking about maybe getting my exhaust done, down here at my local exhaust shop cause they gave me a fair price, thats more on my level. I talked to Tony about this and he said that I could actually lose some power from doing this cause of the way exhaust shops usually do the pipping when bending the metal with excessive heat. He recommends that I just buy a full exhaust. How do you guys view this as an option for exhaust, or should I just buy a full one already made?

 

what kinda price are you looking at by going to the shop?? may be cheaper/better to get a premade one.
