There aren't a whole lot of threads for the T28/T25 guys trying to route that side-flow turbo back to driver's side for their short route fmic. I just wanted to show them how I had it done and why.

I installed the ss autochrome 28x12x3.5 fmic with short route. Guys like me with the side flowing turbo either have to cut their turbo to downflow, fab a seriously tight non-mandrel bend over the crossmember, or u-turn under the crossmember.

If you ditched the crash bumper to install this large ic, and then you get into any fender bender, your fmic is going to be toast. In that case you're going to want to put your sidemount back on so your car is drivable. If you cut your turbo, you can't just reconnect your smic piping. And if you take a tight turn over the crossmember you're going to hurt the flow characteristics. That's why I chose to go under the crossmember. I know someone else here did that, but with stock flex uicp. I decided to have mine custom welded to contour and remain easy to unbolt if I need to put the smic back on. I used 2.5" piping with a 2.5-2 reducer onto the turbo inlet.

Here's a couple pics:





The crossmember behind the lowest point actually dips down, so the licp sits 1 inch lower. It definately is quite low, maybe clears 3 inches to the ground so I have to be careful of that. But I consider it a temporary fix until I upgrade to downflow turbo. I'm thinking about going to a sheetmetal shop and having a guard welded around the licp on the crossmember at an angle, so any low speed impacts will be deflected. Provided I dont hit anything down there I'm happy with it.

Nice work man. I have done the same thing, but with a 1/2" radius so it would go above the crossmember.

Looks good for now, just be careful with bumps

Wow, that had to be tight as hell. Are you the one that had a "V" bend welded there to take the sharp turn? Because I'm pretty sure you can't mandrel bend that small of a radius and cutting it to fit must have been tough. We were looking at how to go over, but I wanted to keep the pipe 2.5 from ic inlet to turbo with smooth flow. I'd be interested in seeing how you did it.

Yeah that was me I am at work now, but maybe when I get off of work I'll snap a few pics and try to post em up (have never posted pics on here before )

Yeah I had a j bent pipe originally that had a 2" radius bend and made cuts using my super sweet geometry skills to make the bend as smooth as possible. Turned out being perfect.

In order to go above the crossmember (and the round hump on it) I had to dremmel off the bottom right corner part of the radiator fan support (if you have taken time to seriously think about how to go above the cross member and have spent time looking at the general area, then you will know what i am talking about). Sorry thats the best way to describe it. But again, i guess a pic is worth a thousand words right? Ok here they are, I forgot to paint the pipe, but seeing how it is a temp fix it should be ok. At least til I get rid of that t-25

Hope that worked!

Wow, talk about using every bit of available space. Doesn't look like too severe a turn to me, good job!

January I'm buying a 50 trim that will bolt right up to my stock manifold, then it's going to be done proper.

I simply modified my turbo outlet with a hacksaw so it will point straight down. Not a very good picture but you can see how the piping comes off the turbo.

I used to have it under the crossmember, but my car was lowered and I drove over Detroit potholes...

This is what I made, worked fine.

i also have a "V Bend" that goes over the cross member.

I like it a lot, no worries when it comes to bumps or pot holes.
