Well I bought a set of silicon hoses at:
www.hosetechniques.com
for my 1993 FD.

Took off literally everything on my FD. Intercooler Piping, intake manifold, intakes and all the etc. to get to the vacuum hoses. It took me three afternoon to finish my job. I replaced all the selonoid hoses with some high quality silicon hoses at hosetechniques.com.

well just finish my vacuum job today. Just came back from a spin and my sequential boost is back and is kicking harder then ever..

Anyways I just want to thank all those in here that help me out with my problem. It was true, there was a couple air leak and a couple in the rat nest that was harden and cracked.

Well anyways I appreciate all you guys helping an 18 yrs. old kid what an RX7 is all about.....

 

Congrats on doing the job yourself, I'd be more than intimidated by it. Well done.
