Which hx40 is best. Lotsa old info on google confusing. Contradicting statements.

What are the exact specs of the 3 hx40?

Which turbine housing do you guys use? is there a wastegateless t3 housing, prefer not to weld it.

How much did your turbo cost?

you need to google the shit out of this. I found sooooo much info on DSM forums when I was considering a holset. The info is more than out there

Tried and still googling. Lotsa info just confusing. Even basic comp/turb size are contradicting lol.

that's because there are a lot of options out there. I believe there is also a giant holset users thread on vortex

Are you looking to purchase one? I have an hx35 with a Timsturbo .62 vband hotside I've been considering selling. Hx40's are absolutely massive, honestly too big for our cars even if you're 2.0

What's the difference in spool between the timsturbo t3 single scroll .63 and the stock 12cm twinscroll t3?

The 12cm is either a ~.63 or a ~.82 (no concrete info on the exact a/r)

This is what I've found. No idea how accurate it is. source- (post #13) http://turbobricks.com/forums/showthread.php?t=165970

9cm^2 - .48 A/R
12cm^2 - .63 A/R
16cm^2 - .83 A/R
18cm^2 - 1.00 A/R
22cm^2 - 1.15 A/R

Several posts of what you posted and several of below (or close to)

But from what I understand hx35 is fine running a larger a/r compared to Garret

From http://www.wrxforums.com/forums/12-turbos-nitrous/19457-holset-hx35-updated.html

12cm = .89 A/R
10.38 = .76 A/R
9.63 = .70 A/R
8.75 = .63 A/R
7.75 = .55 A/R
