Hi, I swapped a b18b in my 92 teg, I used the b18a1 intake manifold which has the FITV under the throttle body. On obd1 b18a and b18b there is supposed to be a coolant hose runing from the thermostat housing to the FITV inlet (or outlet?), then another hose from the outlet (or inlet?) to the intake manifold.

My problem is that I have no place on the thermostat to run a hose from there to the FITV since I have a 1997 b18b obd2 thermostat housing. I have the hose that goes into the intake manifold though.

I guess if I try to start it with coolant the coolant will leak out the fitv. Can I block it or loop it somewhere without damaging anything or creating unwanted pressure? I don't care about having a bad idle on cold startup. Car needs to be street tuned tomorrow!!!

thanks!!

 

please guys its the only thing I need to work out before getting street tuned tonight!!!
I need to know if I can plug the FITV where the hose is suppose to connect to the thermostat housing, while still having the other end of the fitv connected to the intake manifold and not cause any damage.
thanks!!!

 

i would get a tee with the same size hose that you know is running coolant and run that into the FITV...did you use the b18B TB or the B18A TB?

 

I used the b18a tb. I could tee from one of the line that goes through the iacv and tb?

 

i think i am over my head on this one sorry i have just fooled around with OBD1 TB i don't know much about FITV to be honest with you...

 

thanks for the input!

 

you can use the newer TB if you want...
i used all 99 SI accessories on my B18a1 IM...
