We are now in the process of making 347SS investment cast BorgWarner EFR IWG Rx7 turbo manifolds. These will suite the 7670, 8374, & 9180 T4 IWG turbochargers on the FD3S 93-2002 Chassis, both LHD & RHD . These will only fit LHD FC3S rx7s. 8374/9180 on the FC3S chassis do require grinding on the LIM( a few mm to clear the compressor vband clamp). Twin Exhaust gas temperature, or exhaust manifold back-pressure bungs are also cast into both runners. All threaded portions are being rolled before the entire manifold is heat treated. The entrance to the runners are the same inner diameter as the exhaust sleeves, and taper as their reach the T4 flange. This process is not possible with your traditional welded turbo manifold. These will out last and out perform our current welded design. Lifetime warranty for original purchaser also! We should have the first 5 samples in 7 more weeks, then shortly after 30+ manifolds. There is no longer ANY reason to pay someone else to make a copy of our current welded design.
Please bare with us as this is the first group buy we have ever done. Also note we do NOT have a concrete time-frame in place for receiving these. Please do not enter into this group buy if you are not 100% committed to following through. If you want a full kit we can obviously put you down on the list, as we are also in the process of mass producing our IWG turbo systems and by the time these are done will have 30+ worth of full turbo kits in stock ready to ship.
Here is the pricing for just the turbo manifolds per the group buy. We will also knock x2 this amount off per full kit for the group buy( $200 off per 10, $400 for 20, $600 for 30)
Bare manifold group buy pricing only( includes freight in lower 48 states)
1-10 $700
11-20 $600
21-30 $500

We will be updating our blog soon to reflect a better collection of information including all the dynos charts and comparisons etc.
Please note that these manifolds are designed exactly like our welded units in terms of fitment. They are designed to be used with out inconel gasket which is thicker than our standard stamped 304ss gasket. You can use a a stamped gasket, but it does require grinding of the LIM on the FD3S chassis, and even more grinding than normal with 9180/8374 on the FC3S LIM.
We have 7 deposits so far.
