hx40 with a 16cm from a hx35?

[bgilbert]

What needs to be done ? Forrest, Swank, fellow turbo guru's , can it be done, take a hx40-19wg from the junkyard and adapt a 16cm nwg-housing from a hx35?

Bill,



The turbine wheels are different sizes. Hense the I. D. of the turbine housing would be different.

Scott, thats why I'm asking what needs to be done, machining etc to the turbine housing. I was told it has been done, but folks are good at saying things like that, but not give details.

i just put a couple pics in my gallery that show what NOT to do. i'll add some details of what i did later.

I'll hijack my own thread: Dave did you route that 4" flex past the t-case? Might be easier to use flex for a partial downpipe back to the rear of the t-case, then 5" the rest of the way back??... . Also Dave, I must have missed the pics you are talking about. Unless its the ones of the 12 you experimented on. But yes details when you get time.

There are several shops that could do this for you, I'm guessing cost to be $150-$200. You best bet, IMO, would be to find a used 16cm WG housing off an HX40. You will want the WG to protect the HX40.

ok. yes, the flex goes by the 205. the fit would be illegal in all 50 states. . but it doesn't actually touch anything. i've got flex from the little piece i made, all the way to the elbow on the bottom of the stack.



and yes, the pics are the last two which are the 12cm. the mistake i made was not paying attention and starting to cut the bore for the exducer(?), to the diameter of the inducer(?). i think that's what they're called. anyway, after two passes, it was too big. but the long and short of it is that you only have to cut that a little bit bigger, and then adjust the radius for the wheel a little bit. i just put a couple 45* passes over it until it didn't hit the wheel and called it good. probably would have spent a little more time if i hadn't already botched it though. does that clear anything up? let me know.

Well I got a price finally on the 40-19w, $250, seemed a little high to me. Still trying to find out how much a 16w housing for the 40 runs. Then as far as going the direction of this thread, I don't want to give up my 16 on my 35. So I would have to buy another @$135+. Plus machining costs, as I'm not one and don't have the tools. After all is said and done, seems like the cost approaches PDR's rate. I've heard a new stock 40-16 from Cummins is about $650. I might look into that. Course gotta have serial number, cpl etc when calling those guys. Edit: oh yeah I've been a member now for a couple years, and since then (on this site) I still haven't seen a 16 housing for a 35 for sale used EVER, let alone a 16w for a 40, so finding one used probly ain't gonna happen.

I just sold a non-WG 16 housing for an HX35 in the TDR classifieds a couple months ago. There are in there from time to time. As far as a 16WG for an HX40, those are definitely a bit harder to come by but they are around. A little searching and I'm sure you could come up with one.

yes, you can machine a 16cm non-wg HX35/H1C housing to accept the HX40 turbine wheel. and decent turbo shop can do it for you. you'll obviously lose the benefit of the 3. 5" outlet of the HX40, but it should still do well.



FWIW, I MIGHT have a 16 gated housing for you, but I won't know till next week.
