Default Welding onto turbo compressor housing

Turbo: Holset HY35W
Problem: The turbo has a compressor housing that was cast with a built in 90 degree outlet. I'd like to convert the outlet into a regular straight shot outlet. The hard way to get this done would be to cut off the bend and weld on another right? I think the oulet is about 2.3" and I would like a 2" outlet, but if you take a look at the diameter im working with then you realize this could be a problem...

Easier way of getting the job done would be to just buy a dang compressor housing cover that can be machined to fit over the turbo I want. BUT, i can't find much info on other turbo compressor specs for their housings...

How do you want to run the charge pipe? Can you angle the turbine inlet flange so the turbo points more towards the fender?

Turbonetics and Vibrant both make cast aluminum elbows.

atp also carries one if you want a plain elbow with no name cast into it.

um why not just get the cover you want...

it appears you have the generic clamp style holset....find a cover on egay and save yourself $100 bucks in fab work

and your going to need a 2.5 hump coupling to make it work...heat it up to get it over the stock vband'd clamp and have the hump where the ring is...works like a charm

you want the hot side piping to go down where that gap is? Just get a 90deg silicon coupler and be done no fab work needed.

I should have posted a picture of a mr-2 engine bay.
I am currently running a side mount intercooler which has the IC pipes leading in the same direction in the first picture.

I also have a Celica A2W intercooler that I use.

Now do you guys see why I want to do this?

based on my knowledge almost all holset 35 series carry a 4" inlet...the h1c series come w/ some slighty smaller...

i think your best bet would be getting the straight outlet holset housing and using a welded elbow on that to go the opposite direction...vs cutting the existing housing and flopping it 180

Can you just build an outlet out of some thicker aluminum tube? Cut the 90 off and then adjust the tube to fit.
