Internal Wastegate bypass?
 

Hey guys this is my first post plus first turbo build lol.

I'm going to be runing a Holset HX35 on my 3400v6 Z24, forged pistons during winter hopefully, aswell as 3500 valves and some compcam 26915 springs, P&P'd heads, lim, uim, and possibly a few more things lol, but my question is, I'd like to run a 38mm Tial wastegate, is it possible to just weld the internal wastegate solid, and run my external one? I am also going to be getting a Greddy Type S BOV hopefully, if any could let me know on the wastegate that would be awesome though, thanks! If anyone is curious I'll be running Megasquirt V2.2 for my engine management!

i don't see why that wouldn't work. give it a try and let us know. I'm sure someone has done that before

yes it has been done millions of times. why wouldn't it work?

I'd never reallly worked with any turbos before, I searched after I posted and came up with some information, but wanted to be double sure before I hit it wit ha welder lol

Thanks for the info :D

Like the others have said, you shouldn't have a problem doing that.

Sweeet! thanks alot guys, looks like I'll be hitting her tomorrow then

instead of welding the turbo why not check to see if there is a block off plate available for your turbo. i know that ATP sells flanges that will cover the opening of the internal wastegate and have a Vband to hook up your down pipe to. its not all that much. i would look into that first.

Yeah I found one on ebay that blocks it off and has a set screw that holds the flange shut, decided to take that route instead.

ya you can weld or tack it or u can make a bracket to hold it closed..

like he said, ebay should be cheap
