Actually the place where Yukio used to work before sells the AE92 Bomex replica kits
www.infinitivedesigns.com I believe they're out of Cali.
Here's some pics of the original BOMEX kit
You could also go with the japanese AE92 bumpers for a change, they are very different from the north american AE92 bumpers(just in case you're wondering what AE92 means, its the manufacturer code for the 88-92 Corollas)
As for gauge faces, there are none available. Actually there's not too much specific "rice" available for the AE92 Corollas, no Alteezas either if that's what you're wondering when you asked for tail lights.
In Japan and other parts of the world, The AE92 coupes came in 2 styles: LEVIN which has the regular style headlights, and the TRUENO(same as our Corolla GTS & SR5) which came with Pop-up headlights.
Here's some pics of the 89 Corolla Sprinter Trueno GTZ (4AGZE BABY!

)
Here's a pic of a 90-91 Toyota Corolla Levin (on the left) and Sprinter Trueno on the right.
The Corolla Levin
Bomex Kit for the Levin
Here's a pic of what the difference is between the 88-89 (Zenki) Trueno and the 90-91 (Kouki) Trueno (notice the 90-91 has bigger parking lamps)
As for finding a 4AGE or a 4AGZE, depends where you go really. I'm not sure what the prices are but a 16V 4AGE will be a lot cheaper than the 20V 4AGE's or even a 4AGZE. I'd say if you're thinking about a Silvertop or blacktop 20V 4AGE or a 4AGZE, probably about $2500-3000.
