I would more than likely fit. But get ready to sweat some blood when puting the drain line in. my hot-air buddies and I discussed this very topic, but never tried it. It will bolt on, you have to clock the turbo to how the 84/85 is setupped. you have to cut the compressor housing's nose to make up for the short distance between the turbo and the adapter. and since it's not a direct fit, there has to be added sealing. you'd have to get reinforced silicone tubing, like the ones for the intercooled cars. and clamp it down. one clamp on the adapter, and one on the compressor nozzle. some where on the board, some one posted that you can use the 86/87 style drain tubing. I dont know how that works, but hell..it's better than that accordian one, and those are fricken hard to work with...I've gone through 2 trying to put them on. they're really fragile. never hurts to try.

well.. i dunno why.. but the most time ive ever had to mess with the drain tube was about 2 minutes...

but yes, it does work, ive seen it done.

tnt, i asked this very question a few days ago with little help, so i will tell you what i found out by talking to Lee Thompson(hes da man)i have also done a little work on turbo swaps.first take the 87' turbo and clock it like your stock one(line up the compressor side so it points down,and the elbow where the down pipe can bolt up,you will see what im talking about when you put them side by side,may take a few trys but you can do it.)then set the turbo on the intake,the mounting bolts on the turbo will fit on the injector heat shield just like the stock ones. make sure the cone reducer is out of the intake inlet(turbo adaptor).measure from the end of the turbo to the bottom of the intake hole.take that measurement and cut that much off the cone reducer.go a little at a time as you can always cut more.no need to cut the turbo. you may want to leave the oil return hose off till you have the fit right, it is a p-i-t-a to get it in the hole.use a intercooler hose to join the cone reducer to the turbo and some h.d. hose clamps.i beleave you will pick up about 200 cfm with the 87' unit, so yes you will get more power. and you can get a 87' turbo for 100 to 200 $ well worth it, a good bang for the buck! hope this helped.

I was wondering if i could do this WITHOUT cutting the housing! Now I have an answer. The only question now is: Will the hose hold enough boost without blowing off?

thanks for the information but whe i took a look at one of the sites the 84 had two opening and the 87 had two.
