So y wouldnt it work the wheel fits in it i know that dont mean much just trying to findout y ive gotta 2 saying i can

It will physically fit on the hx35, but it will be lag city, usa

It will fit but the opening is to big for the turbine wheel and some exhaust gases will by pass the turbine wheel creating lag. So don't use it.

That's why I said sort quick answer YES. But I apologize for being an ass and not getting into trouble to explain. Yes it will physically fit and yes you still can use it but as the guys said already the difference in the turbines will have negative effects. Sorry again is not my day today if you know what I mean.

Ok thanks for the help

What if i had a hx40 wheel on the hotside?

Then yes, but you would then have the lag of an HX40 and the flow of a 35.

Ok so im better of just finding a hx35 bep t3 housing or bite the bullet and buy one

3mm gap = tip-leakage loss like a motherf*cker

Someone do this, I want to see how bad it realy is.

As bad or worse than a "100 Trim" turbine wheel. But yes, I think some actual testing would provide entertainment.
