What the hell. I have about an inch of room to fit my downpipe. What can I do here?

 

HOLY $HIT what turbo is that?

 

Some kind of ebay turbo. Is there any possible way to make this work or am I fucked?

 

What in the world is going on. You bought a top mount manifold with a center mounted flange, and now you can't figure out why you don't have enough room for a downpipe with a large turbo....come on, man

 

Rear mount.

 

Do they make a flange I can use? Or am I going to have to buy a new manifold to make it fit?

 

The first thing you need to do is give us a break down of your turbo setup. What you have on the car, what you are going to do, etc...

Your turbine housings looks gigantic in those pictures and your manifold has your turbo placed at a very awkward angle. Most top mount manifolds place the turbo forward so there is enough room for the downpipe.

I have no idea what is going on with your wastegate, either.

Give us some more pictures and some information on this setup you are trying to run, AND PLEASE, be descriptive.

 

You sure you have the CHRA in the correct orientation? That looks like the oil drain flange pointing straight up.

 

 

I was thinking the same thing.
I was also thinking "That turbine is HUGE".

 

Yeah, that's not gonna fit.

Having just sold a top mount greddy kit, and I'm currently installing a side mount with a 3" downpipe, I can give you a few hints.

First of all, with side or bottom mount turbos, dp pipe fabrication and routing becomes gobs easier, although harder to bolt up. You don't have to bend it down, forward to avoid the firewall shelf, and then back down along the transmission. This makes it look a little like a question mark (?). With side mount, you're right at the level of that shelf, and by the time you angle it down just a little, you're below it and can go fairly straight. With bottom mount, you really only need to angle the dp pipe down, no bends really required.

Side mount:

Bottom mount:


You can see that you really don't have room between the shelf, brake lines, and your large turbo, to do that ? shaped top mount downpipe. Your options are to try and flip the manifold over, move the flange forward, get a smaller turbo, or start with another manifold altogether.

 

It's not going to fit. Sell your current parts and try again.

 

Why is the turbine housing T88 sized?

Dann

 

If you're willing to cut your package shelf out entirely it might fit, but otherwise you're SOL.

 

Since I can't resist and I enjoy reviving old sayings that people can't stand...
"Why turbine so huge that downpipe won't fit?
Because...well, you guys know the rest."

 

Congratulations! In about nine months you will have a blessed event.

 

Its a reverse gravity drain flange, DUH!

OP: your only supposed to use those (oil drain flange) in the southern hemisphere, it wont work up here. And that downpipe should be L shaped for maximum flow & horsepoerez. Cut at it w/ sawzall until everything looks right. Use zipties to keep it in place but get the thick ones so they don't melt w/ the intense turbo hot hot heat.

 

This must be april fool's joke.
