After spending half the day Playing with the settings on my new Tein coilovers. I started to swap my T28 into the GST to finish "project Just drive the damn car already"

IM using A greddy T28 Dual BB turbo, Off a nissan 240 mated to the T25 Exhaust side housing. I didnt think of this but the greddy uses different water and oil fittings. I could just run ss lines with the right fittings and on the other end, A plain old hose end and clamp it at the nipple off the hard line by the block. For the oil return hack off the bung 6ish inches down and run a ss line there too clamping it as well.



hmmm bigger


my new FMIC its HUGE


Im 90% sure this is the right thing to do but this is my first turbo build so I like hearing a second opinion

on the garrett bb cores you want to make sure the drain is as close to -10AN (1/2" ID) as you can get, as the BB's dont need as much oil in them as jounal turbos. also make sure there is a restricter on the oil INLET side to keep from flooding the turbo with oil.

as for the water jacket. the fittings are 1/4" NPT so they are an easy part so you dont necessaraly have to use the stock banjo fittings.
if your thinking of eventually changing the water lines to SS i would recomend grabing a -6AN Socketless fitting for the time being(so you can finally drive this thing :P). its a brabed fitting that goes on the stock hose and the AN fitting goes on the -6AN / 1/4NPT adapter.
the AN fittings also makes working on the turbo easier later on.

otherwise id just use an angled npt barb on them and call it good

I just called a place in honolulu 50 bucks 4 lines all ss I can bring in the turbo wed and they can make the lines in about 20 min. So close so close.
