For those of you that have this kit, how was the quality of the kit?
My install is going a little slow. My installer has had some issues wit the kit:
1) One of the manifolds did not line up correctly and needed to be shaved / adjusted.
2) Wastegates did not fit correctly, they had to shave off some of the wastegate.
3) The kit did not come with a power steering cooler. My installer is going to fabricate one for me.


I actually went down and saw the defects in the kit myself.....not very impressed with the Greddy TT kit.

Is anyone else having problem with their kit? Anyone run into these kind of issues?

 

I finished my install over the weekend. I assume your kit was in the same production run as mine. I also did not recieve psf cooler. But the hardware was there, so I simply relocated the stock cooler, the greddy one looks like a piece of crap. No need to fab anything there, Just use the supplied hose to relocate the stocker.

I had zero problems with the manifold. Please elaborate.

The wastegates / downpipe installation is tricky. Basically you need to use the allen head bolts to attach the wastegate to the manifold so that you can thread them, but don't torque them all the way. Then bolt up the downpipe, thread all the bolts but keep them loose so that all the parts have some play. Once every bolt is threaded you slowly tighten each one to push the parts onto place. It's not hard, it just takes a little time. It's impossible to torque the wastegate, and then try to install the downpipe, the fit is too exact to install it like that. Basically the instructions should tell you this, the directions are at fault.

I had a hell of a time getting the silicone hoses onto the compressor outlets. I sprayed them with wd40 and they slipped right on. When installing the suction pipe on the driver side turbo you need to put the silicone hose onto the pipe first, clamp it down, then put wd40 onto the hose and use the pipe to push the hose onto the compressor inlet. If you put the hose on that side first you can't get that pipe on. Everything else is straight forward. Crows feet come in handy to get to those hard to reach bolts.

When you pickup your car make sure your heat works. It's tricky bleeding all the air out of the heater core so if your installer has never done this on a 350 they may overlook it.

 

Bini2, youre in atlanta? Ill trade you your car for a G35 coupe 6 speed

 

Good idea for the relo of the stock cooler, I gave my installer the heads up on that. They will probably do as you have suggested.

The bolt holes, for lack of a better word, on the manifold were not in the correct place. They had to shave the holes a little bit and fablicate a bolt to fit.

Good idea, will do.

Thanks,

Hmmmmmm

 

OK, you guys are starting to worry me. As you know, my TT is getting installed. Is my mechanic going to know what do with this wastegate "rings" you are refering to? Is it listed somewhere in the instructions, or is it pretty intuitive to install? Please advise if I should give me installer a head's up.

 

I don't know about you guys but I must say the Kit was not machined with high tolerence. I called Greddy today and they told me I was the first one to call with questions about the waste gate, down pipes and turbo manifold not fitting proper. We tried two gaskets and still leaking exhaust. I asked why we did not recieve power steering cooling coils with the kit. No reply. Don't matter now, we just ripped it out. I think the problem is that they made the kit to fast and went the casting method to make the piping. i know stronger but man! Power Interprise pieces are jig welded. I was just amazed that no one else called and asked about the misfitting parts. Just food for thought. But I do have to say, Turbos are the way to go.

I also wanted to add this. When we ran the dyno run, boost reached 4.9. I guess that is because of the exhaust leak. I added a boost controler and jacked up to 7.5. Big difference. Not dynoed yet. I asked Greddy and they advised me to stop doing that . They said at 4.9 we are maxing out the fuel pump. Just going to tune the **** out of it until it blows.

Oh yeah, their instructions suck. It looks like they zeroxed the instructions. OK no more bitching.

 

But your mechanic in orange county will be fine... if you run into any problems feel free (not free though) to bring your car to Street Image for us diagnose and repair for you.

time to time there are manufacturing issues with aftermarket parts.

especially when products are hot and there is high demand. greddy like power enterprise or procharger will rush the product to get it to market and have some manufacturering defects in the first batches.

As the demand start to drop you will see probably more within spec products.

just my .02

 

Sorry to hear about your problems.
Sometimes things don't appear to fit, but after going at it a different way, like etx meantion, you find it does fit.

and eta, that is the first tip I give anyone on installing the kit.
Get the dam hose on the turbo BEFORE installing them.

On the steering cooler, simply relocate it.
Here is a picture of mine

 

m3powerrr, when you added the boost controller and bump up to 7.5 you did dyno tune at 7.5?

I ran into these problems where there was and might still be an exhaust leak. It was the same spot the fitment between the exhaust manifold / wastegates / downpipes. Will probably have to get the car to the dyno to find out what kind of A/F i'm reading as well as boost level. My boost guage when I punch it has hit 6.9 psi. So i'm not sure if my boost guage is reading false #.

 

Personally, I would take a cast manifold over tubular steel...any day of the week and twice on Sunday. From my experience, even the best tubular steel manifolds inevitably crack, and need removal and rewelding. The extreme heat, coupled with the physical weight of the turbo, and the flexing of the motor, etc takes it's toll.

 

ACP, I literally tried to get those hoses onto the compressor inlets for hours. After spraying them with some WD40 they slid right on!

My manifolds fit perfectly. I hear they had problems with the first run of manifolds, that is why the 2nd shipment was delayed. Does your box have a big red B on it? I believe that is revision B. It sounds like nobody got a psf cooler, I don't care because I didn't plan on using it anyways.

The wastegate / downpipe installation is very tricky. You have to thread every bolt first, keep everything loose. then slowly torque each one a little by little to push the piceces into place. Like ^ said, thier is very little tollerance. After installing them like this everything fit up perfectly.

The kit has been done for about a week now, But I have only driven the car once! It's still a bit wet out here so I don't want to take any chances. The resonated test pipes just arived so I'll probably install those this weekend and hopefully get this thing on the dyno next week.

 

ill go ahead and toss this one in....

the heat shield on the drivers side motor mount... have no mercy. i used a long pry bar and a hammer from the top. There was tons of room to bend it downward and it made a ton of clearance. I have put the turbo on/off several times while fitting for my custom oil lines cause i dont trust the greddy ones... with much difficulty each time. After making clearance with the motor mount heat shield, the thing slips right on, and thats WITH the inlet coupler already on it. NICE!
