Blown Motor, Engine Rebuild/Replacement.

Bought a drone yesterday and going to do some cool photos and video's soon...

Just an update and I started a thread regarding this but it was closed shortly after. I have been trying to purchase another drivers side exhaust manifold since mine cracked and after talking to todd at vivid racing he was sure sam at gtm could fulfill that order. Paid half up front and waited 6 weeks because sam told tod at vivid that a new batch of manifolds were due in the end of February. Again this is not bashing gtm in any way but I just wanted to let people know that I tried to place an order through another company to get a part from gtm for my existing turbo kit. To make a long story short, I had to request a refund due to gtm not being able to fulfill the order. Todd at vivid racing is a great guy and did everything he told he was going to do if gtm did not come through so again I'm needing another exhaust manifold.... I know I can have my existing one welded but would prefer a new one just for peace of mind. My new motor now has almost 3k miles and smooth as butter..

I feel you on this topic as i also had cracked manifolds and tried to purchase replacement with no luck so i just had to have them welded and coated. The welder i use did a great job and put extra metal in the areas where they were crack. They came out good and i just hope they hold up.

Well.... don't worry. They are working hard to right things over there.

How's the drone vids coming along?

COSMO · 03-07-2015, 09:51 PM

Actually I crashed it today because I just had to fly it in the agility mode. Luckily I only broken one of the legs on the landing gear.. If you get one I can't say enough great things about the 350 qx3..

COSMO, gonna use your thread since I don't feel like opening up a new one. I've not caught up much.

Are you still sticking to the GT28RS turbos? I'm thinking in the future if I were to build up my motor I'd like to switch out the turbos for the GTX variety. Of course, that'll require a new manifold to the turbo. I rather not dump another $8-10k on a turbo kit and re-use and retrofit stuff. I'm pretty sure the existing manifolds would be useless by the time I decide to drop the motor and get new turbos. What do you think?

Jon @ Z1 suggested the same thing when I do built block. With the GTX swap they made 609whp @ 9 PSI with the stage II piping, GTX swap.

cosmo, in regards to you needing a new manifold have you seen this >
370Z Twin Turbo manifold - interest thread - DIY turbo kit - MY350Z.COM Forums

DIGItonium · 03-23-2015, 12:34 PM

@jaytirbhaw, we definitely need someone who can fab us some manifolds to fit Garret turbos, and then have a shop retrofit the pipes to our existing kits. I'm sure it'll be cheaper than dumping money on a brand new kit. Plus, be able to install external wastegates.

COSMO · 03-24-2015, 07:12 AM

I may upgrade to the 2871 or 2876 depending what will fit down there..

Garrett GT2876R Turbocharger

O rly?

So I guess we're all in the same boat about the manifold. I'd definitely look into upgrading to the GTX turbos when the motor decides to quit, but I'm going to run the stock block and Stage II turbos for as long as I can. There's no point rebuilding the GT28RS once it's off the car.

Don't blame you. Nice whip btw glad your keeping it.

Stock block with our TT kit and fuel return is 550whp on 93 octane all day.

May even keep my GT28RS if I do built block haven't decided. Yes the turbos would be maxed at 15ish PSI, but only driving her 4 to 5 hours a week isn't much abuse.

Different is the GTX's would complement the power curve for better pulls and obtain 50 to 60ish more whp compared to the GT28RS.

but

You have ask yourself, is it worth the extra $1600 for the swap?

When it is time to drop the motor for a build, the manifolds will need to be replaced as well. At this point, I would have to decide whether to rebuild the turbo or get a new pair of GTX turbos.

You have a lot miles on your kit. GTX all the way and just sell the 28RS.

Well after finally having time to tear down my car again it seems my cracked manifold is much worse than I thought and come to find out there are now 2 cracks... Pics will be up soon.. Thank you GTM..
