this was the ad i saw on CL
3 used turbochargers from late model mazdas. (speed6/speed3/cx7) perfect for rebuilding and using on whatever you can adapt it to. Local pickup only-cash only. $150 for ALL 3.
i went to see the guy he is a mazda mech. i actually went to the mazda dealership where he worked. he said all they would do is put them in the trash if no one wanted them.
anyway my question is is it worth it to pick them up for a cheap build when i know they are taken out for a reason. he says after the cars have been idleing for a whle they smoke. which is a common problem on these turbos from mazda. something with the pcv. my question is are these a good turbo to try to wet my mouth with for a l28 or Ka turbo build. he is just selling the turbos with one water fitting. they are internally waste gated. and they are stock mazda parts. part num is k0422-582.
if i want more boost i have 3 so i could do a TT or a TTT (lol..just kidding) setup.
edit----
i foound this about the turbos. when i do these calculations for the l28 i get 388 and for the ka24 i get 333.
I think that number is based on the Audi/VW 1.8L engine family as this is the same turbo found on those cars. Take 250 and divide by 1.8, then multiply the answer by 2.3, you get about 320 HP which is about what our cars max out at at the crank with CAI, TBE, and upgraded TMIC. (Based on dynos of about 280 WHP, take 280 and divide by .88 {roughly the drivetrain efficiency} and you get about 320. Hope that helps (and is correct).
