Would these have a chance or working on something like say...a T4 holset?

No idea. I have never used one.

Up to 11 deposits and first price break.

Samples are in !

13 deposits

im really liking these

Thanks Rob!

How do I get in on this GB?

By Purchasing the deposit here:

347SS tapered investment cast EFR IWG Rx7 turbo manifold

17 deposits

18!! and we will receive the samples to give a full confirmation on fitment! Then it will be a few short weeks for the rest of the individuals that are not in the first 5! So once we confirm that they are perfect please share with your fellow rotary heads so that we can get to the full 30 deposits to get the awesome price of $500 per manifold!! I will make sure to help towards this goal my self to be apart of the group buy total!

Samples are in and they are perfect. We have test fit them on a mock engine, and in a car here. Identical fitment to the welded versions. All the machining is spot on too.

We are working on an ETA for the group buy batch.

These are going to outflow our welded units now that I have seen them side by side. Every transition is perfect. We bolted the manifolds on a spare rotor housing and looked through and its pretty much seamless transition from the ID of the exhaust sleeve to the turbo manifold. The transition from the round runner to the T4 flange is a lot better than the welded & ported version too. Not to mention they taper as they reach the port where as the welded units do not. We are extremely happy with these.

We will be doing an update for the FC guys in terms of fitment photos etc.

We are at 25, so the price on the manifolds will be $500 plus freight. only 5 spots left at this price.

We have exceeded the # of deposits for this GB. We are now closing this and we expect the manifolds in 3 to 4 weeks. We have started a 2nd group buy( details are in my signature).
