Ok here is my problem... And yes I searched... Im having a hard time figuring out which turbo to go with for my stock GSR turbo set-up... Whats the dif. between the T3 and T4 flanged turbos...


Also on K20a.org someone wants to trade me this manifold and a 4" downpipe for my K series tranny... Which turbo would be the best for this manifold, and is this a good deal... All input would be appreciated in this matter... Thanks in advance...
