I'm buying a new turbo for my 87t2. I have looked at many different ones. Through some advice from Reted and a few othere's I have pretty much decided to go with a Turbonetics 60-1
. However, I am no expert and there are many different variations from Turbonetics when you buy one. This is what they offer.

"O or P trim turbine; .58, .69, .81, .96 A/R “on-center” turbine housing; dynamic or carbon (except “Big Shaft”) seal; wet or dry bearing housing - specify when ordering. 1.30 A/R “on-center” and a full range of tangential-style turbine housings are available as options."

Like I told Reted I'm looking for about 350hp. He said a 60-1 would produce that with ease, with othere mods of course. I know depending on these options will affect my spool up time. Like I said I don't understand much of this so I would love for someone to explain. I will have a streetported motor if this helps. Thanks rotary brothers
