Does anyone know where i can buy a check valve that goes from the pressure camber (green one)? Found mine broken off.. Ive also had problem with secondary turbo kicking in late in first gear could this cause the problem?

 

PM "Dale Clark" on the forum he sells viton replacements

 

Just to second above (from just last month) --->https://www.rx7club.com/3rd-generati...alves-1068461/

BTW RENESISFD, re: your sig... totally agree.
Worked my way through college in a collision shop. Sloppy panel fitment drives me nuts.

 

Another vote here for Dales valves.
I had the exact same valve break the exact same way on my car! Replaced with Dales valves..all good going on a year or so now.

 

That is most likely the root of your problem. It worked for me!
