AE92 VIN or piston part no

Dorito, you just remove the butterfly plates altogether. Running the TVIS ecu is going to be sloppy, but it works just fine with TVIS disconnected.
TVIS intake manifold is just 8separate runners, 2 for each cilinder. There are only 4 butterfly valves in the TVIS plate, they are already bound together. The TVIS plate is simply replaced by the adapter.

The redtop blabla is indeed very annoying. I have the same engine that Zax is talking about, it is an ordinary TVIS engine with red and black letters.
Better stick to highcomp and bluetop. Those avoid confusion.

BTW Zax, does the 87-89 engine really have 20mm piston pin's?
The one I have is just a plain 3-rib block, but these are rumoured to have the bigger internals. It would be a bummer if this wasnt consistent for the 87-89 production range since you might end up getting 18mm pistons.
I'll look up the parts catalogue for you though.
