Re: Turbo mounting orientation
Thanks! I was having trouble finding downpipes going down the driver side. And I already have one that goes down the passenger side. I talked to Phil at spoolin and he said my turbo was backwards. So I was confused

Re: Turbo mounting orientation
yup. I had the cold side on the left and had to trim some webbing but it did fit. Now if i do it the other way the a/c compressor touches the turbo inlet. I grinded away some of it and got it to fit. But I would'nt be able to run an intake on the inlet. Unless I used dryer duct or something. A mesh screen can fit but I dont think thats good for a dd.

Re: Turbo mounting orientation
There are those that use a manifold intended for a 5 bolt downpipe and flip it to work the opposite direction like you're planning, but those individuals create their own downpipes and not search online.
Most people regardless will still put the turbocharger facing the driver's fender and try to integrate a downpipe for a 5 bolt or 4 bolt housing. But that can be more difficult in the long run.
The term "log" manifold tends to be overused broadly to describe both cast 5 bolt style and for tubular steel, which tend to contain a more "centered" T3 flange mounting....
An example. (notice the angle of the t3 flange), sorry for the large picture.
Made to run with this 5 bolt downpipe
Ford style turbocharger
These include the Rev-Hard, Spoolin' Performance, Go-Autoworks, and Inline Pro Cast steel and Iron manifolds.
Some cast manifolds are centered, but are usually T4 flanged.
The tubular Schedule 10 manifolds typically use centered T3 flanges so that the turbocharger can work on either side, but it depends upon the direction of the external wastegate flange or flanged elbow if used.
This includes the same companies of Spoolin' Performance, Go-Autoworks, PFabrications.com, etc.
They work with these downpipes (usually T31 2.5" 4 bolt or converted flanged systems.
With this downpipe
Lastly, there are the "unknowns". Such as tubular nickel-iron "minirams", Kooks-style "Ramhorns" and others that may or may not be A/C or P/S compatible. This is why it is very important that you match the company's downpipe with the manifold you choose. That way there is no confusion in "finding" a downpipe to work with your system, as the more robust companies use a welding jig to ensure that their downpipe works with their manifold. Or, be prepared to make your own.
Independent companies such as Neukin, Drag and others found on eBay expect you to fabricate your own downpipe to work with their manifold.
I know this was a bit convoluted, but this is not as cut and dry as others make it seem. When in doubt, if possible, contact the maker of your manifold to be sure you know which turbine housing it was designed for.

Re: Turbo mounting orientation
Also with the flange at an angle, when mounted on the drivers side, there'd a good chance the turbo won't even bolt up depending on compressor cover size... since the cover would hit the block before the manifold or turbo is fully seated. normally 4" inlet t04e and larger covers won't fit that way, t04b maybe depending on turbine housing design.
plus if you have ac it would never work in the first place, you'd have to cut up the turbo inlet or start grinding on the ac compressor, defeating the purpose of the cast manifold entirely.

Re: Turbo mounting orientation
Yes. There are several companies that i know of that do that.
Blue Ridge Motorsports - (although they don't allow for proper water cooling, due to its placement)... See Revillusion's build.. Below is a T04E fitment.
Doesn't allow for water cooling much.
AFI Turbo (at least they were when it was under its original management), for T04E and T04S.
Below is a Type R with a T67
Hard to fit.. but possible. I'm sure there are plenty of others from RLD, Go-Autoworks, etc. But I just went with the ones I worked with and others recently.
I'm just not a fan of Kooks-style manifolds trying to keep A/C. It just doesn't make a lot of sense to me. But... to each.

Re: Turbo mounting orientation
My Full-race AC ram horn faces the compressor to the passengers side too. In hind sight I hate how intake angels right for the radiator. I got a 4" 45 coupler gt35 and can't fully seat it on the turbo to barley clear the radiator and it still rubs slightly. The cooling lines are run by using banjo bolts and running the cooling lines down. The other thing it took me forever to figure was the oil drain, the typical an lines wont bend enough to make the turn; they always crush. I ended up making custom hose barbs and using silicon hose.

But you're right. In order for a lot of it to work, you have to be...creative in your approach.

Re: Turbo mounting orientation
I love breaking the mold!! I'm doing a budget build right now with parts around the shop... using a inlinepro (traditional 5 bolt turbo housing only) t3 manifold with a 4 bolt t3/t4 60-1 orientated so the compressor is facing passenger side of the car. Had to shave the block webbing like always just have to be creative with the downpipe. Will post some pics when I get home.

Re: Turbo mounting orientation
I wouldn't go so far as "breaking the mold". That's just using what you have there, and being slick with your fabrication skills. Hell, I suppose that would be different considering that most young bucks on here simply ask for where they can find a downpipe to fit thier "unknown" manifold on eBay, and have it magically fit without any work.

Re: Turbo mounting orientation
Everyone seems to think everything should just bolt up these days.
I remember when a 300hp street Honda was radical and uncommon, back in those days everyone had to pretty much build everything from scratch. the turbo "kit" and other "bolt on" parts have truly killed the car modification community imo.
