Yes, I know they are not popular, but I'm considering going to a MUCH larger housing.

I ruled out a 16 because it flows less than a 14wg and spools worse.

Are the 18.5 and 21 housings designed for the H1C, or for the HX35?

Thanks.

The housings will work on either turbo. You should be able to find take off's for nothing. If you can't let me know, I can get you one.

Yeah, I took a 21 to the scrap yard that I would have been happy to give you. I would suggest not going bigger than the 18.5 cm. By the time a 21 spools up the EGT is so high that the turbo can't catch up.

Could you elaborate on this? I've not heard this before. What about a 14 nonWG?

Because its a 14, it spools quicker, then when the wastegate opens it dumps more exhaust than the nonwastegated 16 can.
