advancing your timing will help drop EGT's, too.

I got the gauge from the guy I do work on the side for...he gives me at cost pricing since I work for him. This was the gauge though, not too expensive:

How exactly does that set screw work? I assume closed lets less air through and open lets more air through, but I'm not sure what each end is hooked to and how it works togother? I will search around on that stuff though thanks! That would be nice to drop a couple hundred degrees!

Yeah I thought I had read on here that this turbo maxed out at 35 PSI, so I wasn't sure how it was making more than that.

So that is what's happening now? I take it that little elbow with the set screw is the "boost elbow"?

Drill a hole where?

How much do them go for? Hard to do?

Timing...I'll have to read up on that too.

Thanks again everyone for all your help, I'll keep you posted.

You are correct about your thoughts on the boost elbow and yes, the set screw does adjust the flow of air through it but it won't do you a lot of good with the fueling level on your truck.....a #10 plate on a 215 pump will move a lot of fuel and will easily over power a wastegate that only gates 3 of the 6 cylinders.....you get to a point where 3 out of the 6 cylinders will move enough fuel to continue to to spin the turbo and build more boost while the other 3 cylinders are gated. The hole is drilled in the wastegate through the first hole that gates the first 3 cylinders.....a picture would really help explain this ....I don't have any pics but I know others here do......maybe they will post some? Look at HTT turbo for options and pricing on all the mods you can do to your HX35. They have compressor wheel mods and 14 and 16cm turbine housing mods that can be done to your HX35 to drop EGT's and and make more power.
A good rule of thumb is to advance the timing to 16*......it is a safe amount of advance that will net a power gain, drop some egt and if you can keep your foot off the floor, a mileage gain too!

Wannadiesel has performed this mod of gating all 6 cylinders.....he wrote : "My spare 12 cm housing that I'm trying some stuff on. The wastegate only affects the rear 3 cylinders, so I drilled down through the original wastegate port through the divider into the passage for the front 3 cylinders. I'm hoping this will allow me to get the boost under control, right now I can wire the wastegate open and still make 37 psi! The new port should (I hope) allow the wastegate to affect both ends of the engine by bleeding excess pressure from the front passage into the rear passage, and then out the wastegate. I guess I'll find out one way or another. I also bored the original port a little larger, it's now 13/16"."

I would suggest shooting him a PM for more details.....

I hit 43PSI going into overdrive with my current setup, wastegate was blocked but is now functional.
Waiting for it to die so I'm forced to buy a HTT..

You may need to step up to a 16cm housing if it's that high. I can hit 42 pounds with my 16cm housing...well I used to. I bent the shaft & ground up tome turbo internals from doing it. Yes, keep it under 35 pounds or find another turbo.

Thanks again for all the info...going to have to do some upgrades in the future...just take it easy for now. Here's a camera phone pic...I give my buddy with a turbo'd Honda crap because he hits a whole 5-6 lbs.
