I researched the 14b and decided it would probably be a good turbo for my budget project. It flows a little less than the 15g Greddy turbo and I was going to buy that so it wouldn't be a bad choice. The problem is, the 14b's wastegate opens at around 11psi. I did a search and some people said that the spring or actuator could be changed. I checked Greddy's site and the only springs they had were for 11psi. Then I called turbochargers.com to find out if they carried the springs or could put another actuator on it to lower the boost level. The guy said that it was possible but a lot of work (welding, etc). Then I was talking to someone and they said I could just remove the actuator, weld the wastegate hole closed, and then have a manifold done with an external wastegate. Is this possible? Someone help me out here. I'm confused.

 

WTF???

There was another person posting the EXACT SAME QUESTION AS YOU.

Post "How do I get a 14B around 7-8psi"

look for it. I posted the answer there

 

you can just change the actuatior. and you dont even have to weld on your manni. people have just welded a external waste gate to the outlet flange on the turbo and works fine.
