Does anybody make a 10psi wastegate spring for the stock wastgate of the evo ???

 

Try Forge Motorsport, I believe they make them.

 

Thanks for the tip.. this is what I found on their website

this is kinda vague....

Valve Spring color coding

Green - 5-15 PSI

Yellow - 15-23 PSI

Blue - 23-30 PSI

Red - 30 + PSI

hmm.... 5-15 psi ?????

 

I believe the colored springs you are refering to are for their BOV's. Check with a member Mike@Forge

 

The stock spring is about 10 to 12 psi....so why you looking for a 10 psi spring?

Are you shure about that ???? Lotsa ppl say stock boost on an evo in 18psi.

 

Stock boost without the factory boost solenoid is 11psi.

 

Exactly if you unplug the vac line from the wastegate i get about 12psi.

 

More like 30psi.

 

I did this, I got 12PSI.....

 

If you unplug vac lines from the stock boost solenoid, disconnect & then block off compressor nipple, and run straight vac to stock wastegate you'll get 11-12psi. Disconnect vac from w/gate totally it would go straight up to higher boost levels.

Forge wastegate springs can only work in the Forge adjustable wastegate actuator!! Our wastegates are not adjustable like that, springs cannot be changed...you can adjust the screw on actuator arm...& get like 2 maybe 3 more psi.

thanks for the info.... btw.. what is the name of that selenoid that is attached to the hose ??? (I want to ebay it and would like to put all the right names and nick names for the description)

 

Why would u want to auction your stock boost solenoid? If u are using a stock ECU & u take this off your car you'll get a CEL!!

 

LOL ! I dont own an evo, I am building a turbo kit for another car using evo components.

I'm happy to see the turbo will run 10-12 psi because it's all the boost the aluminum block on my honda can take.
