has anyone put one of these turbos on a 1500 i am building a motor now and want to get a new turbo instead of an old one and was wodering what to get i want something thats not to small either

a GT25 with a 28 compressor (with internal wastegate) would be PLENTY for an A15 and still make up to 350hp.

don't know much about turbo sizing,but you did say you wanted a new turbo.t03's & t04's
aren't new.very old designs.the gt25 mentioned would probably do the trick.something i was told by a friend years ago was that it didn't matter how big a engine a turbo was on,it'd still make the same horsepower,because it would still get the same amount of air into an engine.what was different was where it made it's horsepower,because the bigger the turbo,the more exhaust gases were needed to spin the turbine.so an a15 wouldn't start spinning a t03 until very high revs.this is alright in a drag car,but not in a street car.as for a t04,i don't think an a15 would have enough gas flow to get it anywhere near its range.you could probably get a good turbo off an sr20det,when the owner upgrades to something bigger.i don't know if there's a demand for these,as two times i've casually mentioned about getting an old sr20 turbo for something & both times the person i was talking to had one sitting around.

head over the GTRYDAZ forums or the MRT forums - the forester guys are selling their TF035HMs for $100 - $150 with very low klms on them. i have a pair delivered to my door for $300 and they both have about 35thou on them.

perfect for a std 2L or a worked 1.5L.

ive got a t3 on my a14 and boost doesnt start kiccking in till about 4000-4500rpm
so im looking at going to a smaller turbo like a t25 or similar

Im looking at buying an A15 motor with a blow through turbo setup! Dude reakons he has a lancer evo3 turbo on it. I think he said it is a gt5? If that correct? Are the good turbos? How much would a small second hand turbo cost to suit an A15?
