You need the turbine wheel and housing from the hx35.

So really the easier way is to put the cold side of the hx40 on the hotside / center section of the hx35.

Well guess im going to go for it. Worst case I don't like it and upgrade to a hx35 later on and can use the HE351 on my other maxima. Think I can get mid to upper 300s with it? Also would a 38mm be big enough or think I will get boost creep?

if a hx35 can take you to 550, how is an extra 110cfm going to help you get to 300?

when you spool youre gonna go back to the future

I meant to say I wonder if the HE351 will get me there. Either way I know I will be happy with the HE351.

a hx25 could get you to 400hp with half the cfm of a hx40....

Going to go ahead and do the HE351 will be awhile before I get the car done need new clutch and set of bigger injectors along with fuel pump. I also got to figure out how to route charge piping. That bend kinda makes it a little difficult with current setup so might be doing a little chop chop to make it work. The HE351 being only 9 cm or .65 a/r a 38mm should do right? Just found a nice chart from doing some searching really helped me out. With the whole cm someone let me know if its correct.
6 cm2 = 0.41 A/R
7 cm2 = 0.49 A/R
8 cm2 = 0.57 A/R
9 cm2 = 0.65 A/R
10 cm2 = 0.73 A/R
11 cm2 = 0.81 A/R
12 cm2 = 0.89 A/R
14 cm2 = 0.97 A/R
15 cm2 = 1.05 A/R
16 cm2 = 1.13 A/R
17 cm2 = 1.29 A/R
19 cm2 = 1.37 A/R

ar's are worthless when not referenced in overall wheel size.


200mm to 100mm is .50ar.

60mm to 60mm is 1.0ar

which spools faster

akurtzer57

well it just gave me a general idea on the size. I havnt looked at the maps at all for it. Will do tomarrow getting little late. Might pick up turbo friday night. Looks like the tial 38mm I got should work just fine. Can't wait!!!

An HX25 would never get anywhere near 400 hp.
