Hey guys, got my stock exhaust off and mocking up the turbo. Any issues that you can see here?

Your turbo CHRA needs to be clocked better.

mr steve

needs to be close to vertical right?

mr steve

I have a downpipe with a 5 bolt flange on it, but the internal wastegate runs thru the 5 bolt to v-band adapter... thing is the flapper cant really open that far inside the 5 bolt to v-band adapter. Is it possible to run the wg actuator rod through a downpipe?

bahurd

iTrader: (8)

Yes.

Huh? The V-Band housing is the same as others here and it works fine. You need to port the turbo.

If your downpipe flange doesn't have the same provision to actuate the flapper than no, you can't.

T3 flange on the turbo?

mr steve

I plan on porting the flapper hole and a little on the back side if I stay v-band. I guess i will cut the downpipe and have a vband and angle welded on. see pic

That downpipe isn't 5-bolt... Again, T3 flange turbo?

mr steve

Yes it is a t3, has the t3 flange... dont know why 5 bolt is stuck in my head from my dsm days still.

Yeah I am doubtful that downpipe works at all.

That t3 turbine is likely a Ford t3 5-bolt pattern. Downpipe looks like a t2 flange. If you already have that downpipe you need get a v-band flange on it.

mr steve

anyone ever try to cut the backside off the vband housing and weld a downpipe to it?

bahurd

Why are you insisting on doing things the hard way? Just have a 2.5" v-band welded on the end of the downpipe and enjoy life (assuming that's all it needs, likely a bit of fab work as well).

mr steve

not insisting, inquiring.
i would rather take a little extra time and not have boost control issues later. others have done this but the results won't necessarily be the same depending on turbine size and housing...

here are the specs on the turbo:

T3 Internal wastegate COM.42 A/R 45 Trim.48A/R

• 2.37" Inlet Diameter
• 2.28" Outlet Diameter
• Wet Floating Bearing
• T3 Flange
• Oil Inlet M12X1.5
• Compressor Wheel
• Ind: 1.67"
• Exd:2.37"
• Turbiner Wheel
• 4-Bolt Standard Hot Side
• Ind: 2.52"
• Exd: 1.82"

it is the same turbo used in my mkturbo setups. Port the wastegate hole and you won't have overboost issues. Use a 2.5" vband flange to attach to the turbo. That downpipe will probably need to be modified a good bit besides just having a vband welded onto the end. It's roughly the correct shape, but I'm willing to bet it some if the distances between bends are incorrect.

mr steve

thanks dude ^. everyone's replies much appreciated!

mr steve

good thing I am removing my trans to do a clutch job... this downpipe will not go in

I clocked my CHRA like this. I don't have PS or AC so IC piping was simple to route. V band on the down pipe makes for simple fast install.

mr steve

looking very similar now. where did you get those oil lines?

Paulryan

i bought my entire set up from Shuiend (MKturbo) oil lines as well.
