maXpeedingrods TD05 Turbo Turbocharger for Subaru Impreza WRX STI EJ20 EJ25 2002-2006, with Billet Compressor Wheel, Street JD Series

Original turbo has m12 coolant fittings and this takes m14 fittings. Also there's not enough clearance for one of the mounting bolts. The other 2 are machined well but the one towards the passenger side hasn't been machined with enough clearance to get the nut on the stud. The stock oil drain pipe for the turbo doesn't fit unless you oval out the holes so that's what I did. Bolt pattern is just slightly off. The build quality of the turbo seems to be pretty good overall. Just minor stuff but can become frustrating when you run into one after the other. Those are the only issues I have run into. The coolant fittings I had a feeling about and a td05/td06 pipe and fitting kit will solve the problem. Personally, I just got a couple of M14x1.25 to 1/2” barb turbo coolant fittings and just ran the hoses on the barb fittings rather than getting the pipe kit. We’ll see how it goes. If I end up not liking it I'll just order the kit. Can't really complain too much for the price point. If I had the money I would go with a better quality turbo but it's my daily driver and the old turbo was shot and don't want to dump a bunch of money into my commuter car.

Subaru uses m12 coolant fittings this uses m14 exhaust flange needs a a little a work . The oil return drain has the bolt holes a little off so you need to oval out the stock tube be sides that it works fine and is definitely louder also there's a lot more turbo lag while daily driving it besides that it pulls definitely alot harder around 3k and it definitely makes the car squat once it spools but please people get a tune with this and supporting mods.
