Will it fit? 24v he341ve/he351ve VGT turbos

[THEhomelessONE]

Seeing as there's now standalone VGT controllers, I really want to use these turbos. The he341ve is my first choice but they're much harder to find, so need to know if I can fit the he351ve as well. The hot side housings are huge on these, not sure if it will clear. Manifold in question is one of Otis's, open to others suggestions as well.

Quote from an Audi forum in regards to the h341ve:

"On an destroked 2.1L SRT-4 they are seeing 17psi@1700rpms"

"There is a 2.4L DSM making 22psi@1400rpms, then 30psi@2200rpms and holding it all the way tell redline.. yes he only made 688hp.... but he pulled over 400lbs torque from 1500 rpms tell 7100rpms before twisting a rod from the insane amount of torque from the engine..."

Bump, I've also been thinking about an he351ve, that or adding an Eaton to the system. I'm sure you've researched the controversy about their reliability with petrol EGT's.

IIRC the hotside can open up to 22cm^2, and I'm sure someones tried a 22cm holset on a rapid spool manifold

Sure have, and Holset's VGT can cope with the higher EGT's compared to others. I plan on using e85 as well so EGT's won't be as high. Plus I think some VGT software can read if EGT's are too high and open up the vanes.

Most of the EGT issues came from Garrett too I think. Read on an Audi forum some guy was running his holset so hot that it was glowing red and his engine bay caught on fire, turbo was still good though lol. He had an actuator controlling the VGT, must've not been setup correctly. Mentioned he could hear the turbo spinning up from idle, believe it was a 2.7L

After finding out about people having success with these, I can't bring myself to spending serious money on something non VGT. Sweet, hope someone can chime in and confirm.

I don't like turbos honestly, would rather have a twin screw, but $10k and little room to upgrade doesn't sound too enticing. At least there's turbos now that are closing in on twin screws, good enough!

My diesel Grand Cherokee has Variable Geometry turbo and its sweet.

22psi at 1500 rpm and consequently 420ft/lbs.

I mused about the VGTs on gas engines as well....

Gonna keep following that topic.

Or if your persistent you could program an arduino mega to do the same thing for around $40. Another idea would be to go to your local colleges electrical engineering department and see if you can task out a project for a senior design project and offer to pay for all the materials plus food.
