hey everyone not sure if this post has been made before but was curious to know, if i buy 2 t28 turbos off a jdm s15 would i need to mod anything or rotate the front turbo housing or will it be fine to just fit them to the motor thanks guys
Housings will need to be rotated, along with custom oil/water lines being made. Will need 5 bolt Dump pipes too.
Ive just gone through the process of fitting S15 T28's Turbo center and comp housing need to be rotated you can use the factory oil, water lines. Stock oil return pipe will fit once you slot the mounting holes a couple of mm. comp inlet and outlets need adapters if using the stock piping. The stock S15 waste gates are huge and wont fit, im pretty sure HKS do a kit but i ended up making my own. One of the arms on the waste gate valve should be removed and welded back on at the correct angle as its in the wrong position once you rotate the housings. or buy a kit already done with bb version T28's . i even think theres a set in the for sale section. With either option 5 bolt dump and front pipes are required.
