We currently have a 3 month wait on these. These are NOT in stock, and usually built to order.
Turblown 20B 3 rotor turbo manifolds are built to order and can accommodate most applications for 2nd & 3rd gen Rx7s. Design parameters can be changed for wastegate size, placement, and turbo flange( T4, T6, Vband). Number of EGT & EMAP bungs can be changed based on your demands. Each unit is test fit on a chassis in house. A 3/4" thick steel engine flange is used standard to prevent warp-age, and our new cast 3 into 1 merge collector. The manifold is constructed from 1.5" schedule 10 304SS weld els.
These units have been proven to make over 950rwhp/800rwtq.
