Message	Had a chance to install and dyno a set of GTX2860R Turbos The engine was completely stock, the dyno chart on pump looks very similar to a normal GT28RS turbo with the same mods telling me that the stock heads and cams can not flow any more at the same pressure. The GTX turbos did shine on race fuel...... With stock heads and cams the GT28RS typically only make 620 to 630 RWHP, The GTX2860 ended up making 737 Rear Wheel HP through the stock heads and cams :-) The GTX2863 and GT2867 should produce some awesome results with heads and cams that can move more air! Here are the mods and Dyno. The car was a 1995 Z32 SMZ with 20K original miles. The engine is completely stock and parts were only bolted onto it.
