When i put the Q45 TB on my SR i had a leak at the shaft that fits into the TPS. The orange or red gasket or o ring inside there was bad so what i did was use rtv on the TPS that goes into the throttle body housing. Set the voltage before it dried and i never had a problem after that. I used Toyota Black RTV cause its really thick and tacky. Tested to over 30psi without any leaks.

Mine was on a rb20 but, in researching it I've found that the rb26 has the same problems. The difference is that it can effect the rb26 worse if multiple throttle bodies are leaking.
