We have been in development of a new 2JZ Topmount Manifold that will fit the GT42R framed turbo’s very low. Fitting the Supra with a Precision 82/85 turbo for Son over @ Hyperspeed has helped us to develop this manifold. Matching it up to our GT42R framed turbo and Son’s turbo we were able to redesign our merge collector lowering the entire position of the turbocharger including plenty of thermostat housing/water neck clearance. .
This manifold is on sale now through our online store for $1,795 T4 Twinscroll with Dual MVR wastegate outlets.
