Status as of 10/10/06, headed over to the machine shop Friday and pulled the spacer out to change the bore size. While we had it all torn apart we made some precise measurements on the inake and throttle body bore diameters. We then proceeded with making the changes to the drawing in solidWorks, created some new CNC code and reworked the spacer. I have now been running it about 4 days and can feel a bit more midrange power from the spacer mods which now has the bore matched to both Intake and Throttle body openings. The intake opening diameter was larger than the throttle body diameter so there is a nice outward taper to the spacer bore. At this point I dont feel inclined to do much more on it and need to decide if we want to run a small quantity of units for others to try.

I would just keep the spacer simple and use a straight bore.  Not much else other then maybe adding a larger TB or maybe cnverting to a modern coil would be exclusive to a TBI.

That is basicaly what we have, since I am matching the spacer bores to the intake and TB there is a slight taper because the bore size of the intake is slightly larger and I did not want a lip for airflow to hit.

An adapter could easily be made but you may want to open the bore on the intake manifold to prevent restriction. I have thought about making an adapter which would allow mounting a post 91 TB to the pre 91 intake but more research would be needed.

A lot more research would be needed.  Remember the pre-91's are TBI and not MPFI.  If you really want to go MPFI, you could swap intakes and do the whole fuel rail, PCM, harnesses, the works to convert it.  Otherwise, you'll end up with a MPFI TB and no way to get gas into the engine.

My 87 is drooling over the possibility of a spacer.  How is it going?
