Differences in obd1 and obd2 T/B's (GSR)
I was wondering, if a t/b from a 97 GSR could work on a obd1 mani?
The coolant lines on the bottom are completely different. There is a EVAP canister vac. port on the obd1 t/b whereas the obd2 doesn't.
Thank you in advance. (TIA)

EVAP purge line-in to the solenoid is missing on OBD-2 TB's.
FITV is missing on OBD-2 TB's.
I'm OBD-1 as well. I have both on my desk and I'm gonna probably use the OBD-2 TB for the overbore and bolt that one on. I won't need the FITV, and the EVAP line - I'll just tap into the intake pipe.
Look at the EVAP purge diagrams in the manual. It can explain everything if you look and think about it for a bit.
