Really? The guy at Greddy said if use the DE manifolds that come with their 18g kit then my 20g turbo will be hitting the bell housing on my HR motor. If that's not the case then I wonder if Greddy has any spare DE exhaust manifolds laying around. They said they have a couple of passenger side HR 20g manifolds but no driver side manifolds.

Aside from that, the turbos are mounted in front of the transmission... so I do not see how they could hit the bellhousing even if there was a different.
PERHAPS there is a very minor change in the angle of the 3-bolt flange, but I really doubt it. They look indentical to me. I have held the DE manifolds a dozen times or more, and I didnt notice any difference in my VHR manifolds.

On an interesting side note. I did not want to start a thread about this yet until there is something more tangible in my hands.
A few days ago my welder came over here and we looked at building replacement thickwall elbow manifolds for the Greddy manifolds. We decided that it is not ideal. The 3 bolt flange is offset high up in relationship to the ports, and getting the furthest back runner into the collector would be a nightmare, it could really only be done well in that layout with a casting.
So we moved to the next step. We laid out the flanges in CAD and we designed some thickwall damn-near equal length manifolds. We have started to machine the jigs, and I have ordered some laser cut exhaust manifold and greddy turbo flanges from my laser/waterjet guy. I will have the flanges next week. Hoping to finish the jigs this weekend.
While the manifolds are "done" in CAD, I did not have boundries in the program. Its possible that the runners could be hitting something. If they are hitting something, I will have to move around the configuration in CAD, and see if I can get them to hit nothing. I will know more soon. We have to tack them together in the current configuration and see if/where it hits, and then reroute in CAD.
So basically we are gearing up to build a couple sets of equal length thick-wall manifolds that are a replacement to the Greddy manifolds. Pending some boundry details, it still might not be possible to do well. But if it is possible, we are going to do this. BUT i need to add that its also very very likely that the tubes may conflict with the water pipes on either side of the engine, it really just depends. If they do conflict with the water pipes, it might be an unavoidable side-effect of an equal length tubular manifold that puts the turbos in that location. In that scenario, if thats the only confliction, I would still build the manifolds, and anyone who wants them will have to make alternations to the water pipe(s).
We were already planning on doing this for some T25 manifolds for my 370z... so we are considering this an easier warm up, thats why I sort of jumped into it. We have built plenty of turbo manifolds over the years, we just never got into that with the VQ scene. Its sort of a pain in the *** car for this type of stuff.
So this is not a guarenteed thing yet. I just wanted to say that we are pretty deep into playing with this right now, and its quite possible it will result in a finished product.

does anyone have a toast greddy turbo laying around? i dont want to remove mine off my 370z since the car is running/driving. we have my old 350z to test fit the manifolds, but it would be great to have a turbo so that i can make sure none of the runners wack the turbo anywhere.

Just let me know where to send them and I can get them shipped out Tuesday

Ok, I've put my car back to stock because of Greddy's lack of product support and I'm selling everything off. I've got an almost full Greddy 20G TT kit just sitting in my garage that is virtually useless because I have no exhaust manifolds or the wastegate relocation pipes in order to sell the kit

I was going to say $3k and they get a used TT kit that was tuned at 8psi because it's always been on a stock block. Even if it costs $1,500 for a set of manifolds and those little wastegate pipes (parts 5,6,9, and 10 on the 20G parts list) they still get the kit at half the cost of a new one. I just had the down pipes thermal coated with that 2,000 degree black textured paint by Jet-Hot. The parts that are missing were on their way to Jet-Hot also but never made it.
I'm open to offers and I can send pics also to verify everything. I sold the brand new built motor I was going to use also so I'm ready to get rid of the other big ticket item too haha

I've had them on the car for 2 summers at about 8k miles total. Almost all of that is highway miles going to events, Dynosty, and Miami a couple of times all from Indy where I live. The Z is not my daily so the the car has never seen snow or salt from the roads or anything. Feel fee to PM me with an email address if you want some pics. I can take pictures Monday because I'm downtown this whole weekend helping out because of the Super Bowl
