I just finished fitting a GT2871R turbo in my '95 Escort Cosworth. I've been a bit easy on it since we just finished doing a rebuild. The turbo seems to spool up faster than the T35 - it feels stronger in the 2500-3500 rpm region. The Gt2871R is good for 400 hp. Fitting wasn't a direct fit though but wasn't too bad. We had to modify the Mongoose downpipe with a V-Band clamp. Also fitted a ATP Bolt-On internal Ultimate wastegate and their oil return line adapter. We had to fabricate new coolant lines since the banjo fittings are a different size. Once I get the engine broken in we can retune it and I can give a better report on the turbo differences. hopefully I can get a dyno plot then.
