Turbo six cylinder in a Satellite

Isn't the 518 a lock up converter? if so, then no, won't work. All the Holset 35 will make a great improvement over your present turbo just because it has a 12cm exhaust housing that will spool up like mad compared to you baby holset that has, at the vary, most a 18cm and i'm willing to bet that is a 21(won't spool up until high gear)
The one that i had on my 91 non intercooled was off of a 97 and the difference was night and day!
The difference between the 35(hx,hy) compared to the 351. The 351 will spool slightly sooner. So the best on to find is the 351. and all of these turbos will bolt onto your exhaust manifold. all will require clocking to fit your application and all will require modification to the oil drain back to the block. for all the work that you have done to that car, these mods will be simple!!! Just pull the lever and buy one. Ask for a picture of the fresh air side of the turbo. If the wheel had rubbed the housing,move one.
