Is there such a thing as a 3½" turbo inlet for the stock turbo on '87 cars?
Haven't seen it in anyone's online catalogs. A 3.5 inlet would be a lot cleaner looking when used with a 3.5" MAF, as it avoids all the messy adapters and hose clamps.
Just go with one of my 3.5" MAF pipes. The 3.5" adapters I use squeeze down nicely to the 3" inlet without any problems and looks pretty clean to me. http://www.buickgn.com/mafpipes3.5INCH.htm
I originally had upgraded to a 3" LT-1 MAF sensor but when a customer asked for a 3.5" pipe, I upgraded to the LS1 sensor to make sure this would work and it fits nicely. I would recommend using an Angle Boss IAC relocator though.
Yeah, it worked out pretty slick, no need for a 3.5" to 3" adapter. Guess it would work out the opposite way for those running a 3"MAF pipe that wanted to go to the 3.5" MAF. I wouldn't run it on my GN if it didn't work.

Will you be at the GS Nationals, or will there be any vendors selling the 3.5 inlet pipes? I would like to purchase a steel one and would prefer to pick it up at the Nats.
