I was curious if this turbo would be a decent upgrade from my hx35.

Garrett
1.00 a/r compressor side
59.87mm, 80mm

1.00 a/r turbine side
76.2mm, 69.84mm

thanks for any insight you may have.

I'll take a crack at it.

So I take it this translates to be a 60/70/XX?

Seems a little big on the hot side, but could be usable?

I dunno.

the 1.00 a/r on the exhaust side roughly translates to a 17cm2/18cm2 housing.

I can get the turbo for $75, maybe less. So it is awful tempting.

It is also wastegated so if I were to pick it up would it be something I would have to use the wastegate with or just weld it shut??

Thanks guys

with enough fuel, you should be able to spool it alright. is it by chance wastegated?

59/69/17or18??

sounds laggy and top-end-less

haha
not so much to me. the smaller than usual compressor wheel might help spool up a bit and still be large enough to supply plenty of air. and a wastegated 17 or 18 housing could help spool even a little bit more. i know that if my stock h1c had a wastegated 18 rather than a non-wastegated 18, it'd probably spool a little faster than it does now.

what's the formula used to convert an a/r ratio to cm2??

There is no exact formula to convert the two, just decent estimates because cm2 is an exact measurement and A/R is just a ratio. An A/R can change based on the frame of the turbo(T3,T4,T6.....) as where a cm2 reading is an exact measurement and is what it is regardless of the frame of the turbo.........that being said I found this on the 4bt forums. It makes this turbo more of a 14.5cm2 exhaust side rather than the 17/18 I thought it was. Not sure if it has any credit whatsoever but here it is.



((cm2x8)-7)/100=a/r


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
20 cm2 = 1.45 A/R
21 cm2 = 1.53 A/R
22 cm2 = 1.61 A/R
23 cm2 = 1.69 A/R
24 cm2 = 1.77 A/R
25 cm2 = 1.85 A/R
