Will Evo 8 turbo work w/ 14b exhaust housing?

[Detail]

Hey guys/girls,
I have a brand new evo 8 turbo (twin scroll one) from a customer who upgraded to a gt35r. I drive a 95 talon tsi awd currently running a 14b. The question is if the evo 8 turbo would work with a td05 or td06 exhaust manifold. I understand that the turbo faces the wrong way to begin with hence why I want to pull it a part and stuff in it a 14b, or 16 exhaust housing.

start the debate...

I say try it out (measure!!) and let us know the results.

Will do this week while at the shop! I was wondering if anyone had done this as of yet? I have to take the exhaust housing off, I have a 14b exhaust housing laying around and I'll give it a whirl. Chances are it will fit, how it works might be another debate in itself. If it fits I'm guessing I'll have quick spool with a little less top end then if the turbo was in its stock state. Wish me luck!

It will not fit, I have already tried. Even if it did, the turbo is flipped around on the evo 8. The fins would not be pointing the proper way in order for the air to spin the wheel right.

Wow, I completely blanked on that one. I guess if you could find a way to mate up a tdo5h turbine wheel to the comp. wheel it might work. But, at that point I think it's too much work just for an 80hp bump. Since you got the stuff for free, I'd try it anyways just to be unique.

The evo turbo spins in the wrong direction, after putting the turbo onto the 14b exhaust housing (assuming it even fit), it would be spinning bakwards. All dsm turbo's spin clockwise when looking into the compressor housing, the evo's spins counter clockwise.

You could go to alot of trouble to make it work, but it would require a new manifold and intake setup which would outweigh simply buying an evoIII 16g turbo in its place.

You could do like a local guy here did and use an evo mani with the turbo. It took some pretty radical workings to make it happen, but the car went some 11.30s with the setup.

Yea, that would work fine, but it looks like he had to relocate the power steering and alternator. Actually I'm guessing he re-located the power steering to the garbage can .

I was psyched to see his car run an 11.3, all I got was it standing still.

 

[b00st3d]

here's an 11.53 pass...

11.53

dunno if we have the 11.3 hosted on the site...

well the news:
As stated it won't fit straight up to the car because it spins the wrong way. HOWEVER, it will fit straight in a 14b exhaust housing. Might full around with it, see if I can't buy a new shaft for cheap with the blades the right way. Might make a cheap 16g for me, who knows.

You CANT just replace the turbine wheel/shaft. The compressor housing and wheel are also reverse-rotation. If you REALLY want to do an EVO8 turbo on a DSM, the simplest way I can think of is to fab a tubular exhaust manifold that rotates the turbo 180 degrees so the compressor side is facing the pass. side of the car.

the simplest way I can think of is to fab a tubular exhaust manifold .....compressor side is facing the pass. side of the car.

I am currently doing that. It is not a simple fab job. This is the third time I cut the turbo flange off of the tubular header.

1. The Evo8 header bolts up to the head, however the evo ports are larger than the 2g head ports. I welded/surfaced/ground the header flange internal ports to "match port."

2. The Evo8 header with a 180deg "spin" (cut-weld) of the turbo flange pushes the E8 turbo into Talon radiator. Extra tubing must be welded after the flange is cut.... so as to rotate the turbo closer to the block.

3. E8 must be rotated up (clockwise from front of vehicle) to keep exhaust out of oil filter.

3. The waste gate actuator bracket must be cut and relocate - fab'd

4. Depending on the "relocation" of the actuator, an index may be welded on the wastegate lever such that the actuation geometry is correct.

5. o2 & exhaust is very close to oil filter.

6. O2 is very close to alternator (02 hot...alt no like) cut-fab SS-O2 for more room.

7. O2 sensor close to poking into alternator. (relocate O2?)

8. water crossover tube must be cut-fab'd to avoid wastegate lever.

9. power steering bracket might need tweeked to avoid fab'd cross over tube.

10. oil return tube must be fab'd.

Do not attempt this without a good 4.5" grinder, MIG or TIG, Flat belt sander (not a belt sander) experience, & time. If you are learning to weld YOU WILL F*UP.

My uncle was excellent at fab'ing... he once told me "Bob, leave well enough alone" (translated - use an EVO III).

I have a hard time using this advise...for this, I have made some cool things.... and in other cases I have wasted a lot of time

I didn't say cut up and re-weld the flange on an EVO 8 header, I said fabricate one - as in make it from scratch so it fits a DSM. The wastegate actuator problem could be eliminated by doing an external - you'll need a custom tubular o2 housing anyway, why not throw a Tial 38mm on there?

I wasn't implying that it would be "simple", merely easier than trying to make a clockwise wheel work in a counter-clockwise housing or vice-versa. If it was easy, everyone would be running one.

or like me, forget it and move on. i really didnt think we'd have this much discussion! quite amazing. good luck to you man, thats going to be a pain.
