Koen's 86 - every drive a new issue

[banpei]

Wow! You've had some great 86-experiences!
That Suzuki-powered rally car certainly is very interesting.

About the homologation: yes, those FIA specifications are quite strict. If I remember correctly, Toyota homologated a few more options later throughout the AE86 life with stronger rear axles and such. But everything is supposed to be OEM-Toyota.

About fitting your current ECU to the 7-rib engine: this depends on the engine specifications. Here in Europe, the non-cat engines are supposed to have a higher compression ratio (10.0:1 versus 9.4:1) as it would be allowed to run on leaded gasoline. This means the fuel maps between cat and non-cat are different. Similar to the AE86, the MR2 came with cat and non-cat versions.
