GT2871R: Bigger than the GT28RS, ATP's GT2871R has slower spool, but can handle around 400 horsepower. This is a good turbo for built-engine 2.0L WRXs that don't mind adding some lag for some more top-end performance. This turbo is still pretty small for a 2.5L, but will have rapid spool if you decide to go that route. The GT2871R uses a 53.85mm 76 trim turbine wheel and 71mm, 56 trim compressor wheel. GT3071R: ATP's GT3071R is a great match for the 06+ WRX & 04-07 STI's 2.5L engine, especially if you're looking for boost threshold that is close to stock but want enough airflow for 450+ hp. Almost all the boost is available all the time; even at part to medium throttle!. Boost recovery between gearshifts is awesome with full boost ready even before upshift is complete as the STI lurches forward with shear enthusiasm at the onset of each gear. If you have a built 2.0L and are shooting for 450+ hp, this turbo will work, although it will have significant lag. The modern generation of Garrett wheels, coupled with an awesome wheel ratio, allows even the smaller displacement EJ20 engine to provide adequate motivation to get the GT3071R going for a great powerband. The 3071R competition-grade turbo still offers the best response and spooltime out of any unit in this flow range. The GT3071R uses a 60mm 84tim turbine wheel and 71mm 56 trim compressor wheel. ATP GT3071R Dyno - 400+ hp & tq! ATP has run a 12.6 1/4 mile with the GT3071R turbo on a stock STi with a 3" bellmouth downpipe and ECU reflash only! rapid spool sur GT2871 Ok mais c'est à dire ? 1bar à 2800 tr/min ? contre plutôt 1bar à 3200tr/min avec GT3071 ? sinon quelle pression max à 6000tr/min ? on peut avoir 1.2b ?

bonne question ... on a pas trop de retour mais par exemple today, après un bon démarrage en 1ere et quelques épingles en 1ere ben ca sentait fort de l'embrayage ... déjà c'est l'embrayage qui ramasse et pas la boite sinon sérieusement les BV des 2.5l sont plus longues en 1/2 que les anciennes wrx donc je dirais 340cv et 45 de couple
