i wanted to know a little about the hx 40. i found one on craigslist at a fair price it said it came off a 99 volvo diesel. i was wondering about the comp. wheel size and exhaust housing size on such a turbo and if it would be suited to my first gen. i want sumthing that spools better or at least equal to stock and about a 62 or 64 comp wheel thanks
also i noticed in the pic its a 6 blade comp wheel. is that good or bad? thanks

 

STAY AWAY !
1st it's probably a T4 flange you'll need an adapter.
2nd with 6 blades it he standard HX40, you really want the Super HX40 with 7 blades. It flows lots better.
I picked up one with an HX50 turbine on it and by the time I got the adapter on and then the '40 the compressor outlet is right against the fender and the wastegate is unreachable - that's why I have 47psi boost with the wastegate operational...I unhooked the wastegate once - that was enough - see my sig.

 

so an hx40 is a 60/65/17? that aint much better on the exhaust side as far as spooling and heck id be better off ugrading my stocker with 60mm comp ugrade and new exhaust housing

 

no an hx40 off a volvo is only a 56mm wheel and most likely when it comes from a big truck it will probably have an 18cm housing. stay away from them they suck

 

That's what I thought also but I bought it - for $250 - for the airflow.
And it spools - I'm guessing - at least 50% if not 75% better than the 18.5 H1C that was on it. Plus the WOT boost is nearly twice what I had with the wastegate inoperative.

With my valet on which locks the fuel pin I can still hit 25 psi whereas the H1C would only go to 15 - 17 psi and there's only a moments hesitation before the smoke clears up. With the valet off allowing the fuel pin to move I can blow some smoke but it still clears up to a heavy haze pretty quick.
Yes, I'd like a 16 turbine but I holding onto this because I think it'll be a good turbo for twins the way it flows. Won't really know 'til I get a second turbo.

 

damn u must not be fueling much cause my stocker hits 25 psi easy. it was doing bout 30 but i turned my fuel down a little

 

ya mine stock did 20-22 as well and with a fuel pin did like 28. my hx40 was a lag monster especially on a 5 speed the thing sucked. now with ym phat shaft when that baby lights its hard to keep it between the lanes she wants to move

 

yea man i want sumthing good but i just dont know i f i can justify spend 1500 -2000 on a turbo

 

i picked up my phatshaft from luke for well under that. and itll be cheaper to buy one now then to keep buying 2 or 3 that dont make you happy and by the time you lose money on all of them itll be cheaper in the end to have just bought a nice new one with a warranty

 

Jake - that's with my valet switch blocking the boost from getting to the afc....
Maybe I'm expressing myself backwards -
valet on = no boost to afc
valet off = boost to afc

My stocker was hitting 30 - 32 but I went my 6x.016's and overwhelmed the poor little thing. Besides I found someone willing to give me $100 for it for his ricer. Hope he enjoys it as much as I enjoy my Super '40....
