He did mention making a whole new manifold out if SS and offer them to others to buy useing my existing manifolds as a mold. That being said I would get the first set and fit them as trial and error before they are to be sold so no ones runs into fitment issues. Bobby said they would Warranty the parts but at this time I'm sure for how long. I honestly don't see this process lasting more than a month or so if things go well so be sure to check back periodically on the updates. Again it's a real shame gtm has resorted to tucking their tail between their legs and not addressing their major flaws leaving us the customers to fix them but I'm confident things will work out without the help of them...

Please PM how much they quoted you on new manifold.

Two vendors should thank GTM now :rolleyes:

Boost performance for marketing
VSR for making money from manifold :rofl2:

On serious note: If VSR manifold went into production before GTM v3 upgrade then screw it, count me in the group buy if any without even taking my permission..

The community should thank the two vendors you mentioned, because we brought out the true colours of ALL the vendors that offer forced induction options for this platform :).

(I don't really need a thank you, just say'n)

I see a light at the end of the tunnel. In for VSR manifolds.

I'm in for manifolds!

Dont those manifolds give you guys grief with the steering shaft and make you have to drill and tap the cylinder heads, etc? I wouldnt buy those manifolds if they were for sale, and a stronger duplicate wouldn't appeal any greater. If VSR wants to cast manifolds, I would ask them to do you a favor and toss those in the trash and do something all new :)

All I care about VSR manifold is strong enough for real track users and DD people... (unlike the ones that are made for dyno queen only and garage parked the rest of its life :rolleyes:)

I don't care if the design is trash or not. we already drilled the cylinder heads.
After I saw the flange smaller than the gasket then that's the only thing I would like to point out to VSR to improve besides strengthen it up.

Good point that's why I made it a point to tell bobby at vsr about the unneeded drilling and tapping. If they can replicate they should be able to make them without needing to drill and tap. One step ahead of you guys...;)

Yeah isn't that a shame that they couldn't even get that right while designing them..

I dont think they designed them to begin with. I will have to dig through old photos but I am about 95% sure they are copies of the old HKS manifolds only with that strange proprietary 4 bolt wastegate flange added. If that is the case, it would possibly explain why they wouldnt fit very well without the same little turbos HKS was using in their now long discontinued "turbo starter kit" they were selling for 350z/G35. It was a bare turbo/manifold kit and the buyer had to fab up IC and piping. Really an awesome idea because so many people would love to build their own kit, but manifolds on this engine layout is just too hard for most fabricators and DIYers. But it didnt take off.

Ah yes, here we are.

For a brief moment, GTM was marketing this GTM/HKS turbo kit that was based on the HKS turbo starter kit I spoke of. They didnt market this much long at all before they had their own manifolds for their own GTM kit.

Judge for yourself, but looks the same to me. Anyone feel free to correct me if I am wrong, but based on what I am seeing, I am pretty sure that the only parts they engineered in their turbo systems were the intercooler pipes and wastegate pipes.

You are correct sir they look Exactly like them...

You can judge better than I, I dont have a set of those manifolds in my hands right now to compare to the detailed photos in that thread.

But if that is the case, it probably sheds a lot of light on the issue with their new manifolds. This is not the easiest car to be learning new things on.

Damn.... Just keeps getting worse n worse...

Sad thing is....this was only the first thing this company his ripped off....research is priceless.

IMHO, don't wait for the v3/modified MHI/scrapped MHI/failed MHI/made in godknowswhere headers if you are looking to keep the GTM kit(v1 or whatever). You would likely need to fab downpipe/ic piping for a start, god knows what else.

Luckily VSR is taking these on for you guys, but it will take Bobby and team a miracle to perfect these, I wouldnt put it past them!

It's pretty easy to see why HKS could not give a damn if someone stole their manifold design....that **** is ugly. If I was in market, I would have gone greddy all day, but that's just me.

Still rooting for ya cosmo, wherever you go with your build, go large! Thanks for progress on your build, been an interesting read on my vacation!

Hey thanks faceglide, I know I have mentioned this before and going to mention it again but I honestly think I'm going to sell my gtm stage II Twin Turbo kit and go with another. I even have a set of their 3" downpipes to go with it but I really need a set of stock exhaust manifolds... I know some of you may or may not have your laying around. The thing is I've been talking to other turbo manufactures and looking for a deal since I do have a built motor to see what some of these kits can really do. No decisions have been made yet but whatever it will be it's going to be pretty awesome... My used gtm TT kit will be put of the forum very soon at a great price since it only has 3k miles on it and it will be sold with the fixed exhaust manifolds or new fabricated ones...
