does anyone know how to adjust the wastegate? i've read that there is a nut you turn to mess with the psi? i'm a 2.2 with the k04 and i spike 15-20 pounds wayyyy to much and annoying. i want it at about 10 psi.

 

If you connect the wastegate directly to a boost source you should hit somewhere around 8-10psi.

 

You could always hook up a manual boost controller.

 

peachpuff what do you meen? tommy i'm gonna order one either way but some people said i cant use that to lower boost? but would it since the ss is controlled by the ecm?

 

lol you can't put a bc on and lower the boost past what the wg spring is rated for.
if there's no adjustment you can always pull the iwg and weld it shut, and get an ewg.

 

In your case a mbc is totally fine to use with the k04. I wouldn't honestly mess with the wastegate adjustments really unless you know what you're doing though.

 

soo if i get a mbc i could set it for about 10 psi as full boost?

 

no

 

Yes you should be able to as far as I know. A buddy of mine had a k04 on his le5 that he ran 10-12psi on without any issues.

No? Does the k04 have a 1bar spring in it stock?

 

He's running off the gate now. so whatever the wastegate spring is he will hit. he thinks that if he puts a mbc on he can decrease that amount of boost. negative.

 

ones saying yes ones saying no. i need to know lol.. its annoying when my clutch slips and i hit 15 psi and lean out. therefor i have to watch the boost gauge to let off

 

it's no. you are on the right track with trying to adjust it, if that's possible.

 

how would i go about adjusting it?

 

Well, you can try tightening up/extending the wastegate rod but you may have to get an external wastegate and just plug off the stock turbo wastegate. A boost controller can only adjust down to the wastegate boost itself. Unless you can find a lower boost wg actuator off another turbo to retrofit.

 

Slowline is probably right here then. I for some reason thought that the k04 had a .7bar wastegate spring stock and not a 1bar.

 

i also thought stock was 7 psi. can you explain to me as if im a retard how to adjust the wastegate? my manifold had a place for a external but we welded it shut...

 

I'll have to find out how my buddy got only 10psi out of his then. Unfortunately I can't have that answer for you until tomorrow morning though.. lol

 

That's fine man f you want txt me ill pm my number

 

Extend the wastegate by loosening both nuts and cranking the one closest to the wastegate actuator(where the vac line is hooked up) towards the front of the car if you're on top of the engine bay or towards the back of the car if you're under the engine bay. Then crank the nut furthest away from the wastegate the same way until you start feeling resistance. Then tighten the one closest to the wastegate actuator towards the back of the car if you're above the engine bay
or towards the front of the car if you're under the engine bay until its nice and snug on the rod.

 

You may have to loosen the one closest to the actuator more as you try to get resistance off of the one farthest away or you could bottom out on the nut closest to the actuator and you don't want to do that until you feel resistance. Not caused by the nut closest to actuator but the wastegate itself.

 

subed for when I get mine going

 

any pics?

 

put a vacum hose on the nipple on the wastegate, then run it to ur manifold, or anyplace u would usually hook up a boost gauge to read boost, and the turbo will only boost as high as the spring in the wastegate is set to. that should be safe till u get ur boost controler
