Engine/Transmission (1994 - 1998) a good turbo

[jimpotent]

I am in the need for more power. But a strong turbo.

Something for everyday driving and tire smoking fun.



I was offerd to purchase a hx40 turbo but read that they hate turbo bark and can wear out fast. What other options are there

for me



My truck is a 98 12v 3500 2wd DD stage 2 injectors, tst#4 plate,straight pipe 4 inch,pro tourqe convertor,elbow screwed all the way in, valve body work. open element K&N. Truck weight

8200lbs 15. 70 @84 mph



This is my work truck and tow truck. I would love to see 14. 00

I met a guy that takes his fuel plate out at the track he gained

like a second. . Is this safe to do ? He seemed like he new what was up but recommended me to keep mine be. . Cool guy has fun

just like me

HX-40s are good turbos, just don't bark 'em or bash on them ALL the time. It's not that hard to prevent barking by not doing it or just purchasing the blow-off valve. You might want to look into a PDR HX-40, not sure what Piers does to beef it up but I have heard they are better/reworked 40s rather than getting a plain stock one. You don't have to have a big turbo to make gobbs of power. I am still running my HX-35 and making 36-38 psi at every shift. HX-40s fail due to them having the same size shaft as a HX-35 but with bigger compressor and turbine wheels and the shaft tends to break depending on use and abuse.

It doesn't say on the website, but is the 16cm2 housing for the PDR HX-40 non-wastegated? The pic shows the turbine with a wastegate but I thought that might be a 14cm2 housing in the pic.

The one I'm getting is gated. Might be able to get one that isn't, don't know for sure.

i run a usb1 from bell and Pius. its a stout unit that is wastegated. there are a couple people on here that are running them. i like mine a lot it spools up right now and its "good" to mid 50's for psi. i peg out my boost gauge so i honestly cant tell you what i am boosting to. i know people are running them alot higher than that though. it is a 4" outlet so you do have to address your down pipe. Mr Pius sent me everything i needed so i cut off the old flange and welded the new one on. they arent as expensive as one would think either. Mr Pius is a great guy as well and if he has the time will answer what ever questions you have. just my . 02

PDRHX40-16

You can get it with a 16 or 18cm exhaust housing and both are wastegated. Oo.

Well, then what is the advantage, if any, of going with a non-wastegated 16cm2 turbine? Obviously the wastegated version gives you the option of running what ever boost you want, but what kind of boost numbers and advantages does the non-wastegated do for ya?

hi Jim,

it's Lenny (the guy who took the plate out),the turbo a have is from diesel dynamics. this turbo from what i gather pretty much handles 50lbs of boost with out a problem. i've seen the turbo that i have handle up 70psi for over a year now in a 86 chevy daully c pwrd( with a fire ring in the block) towing busch north car trailer well equipt wieghting 15k, makes my 13. 2 e. t. truck look silly

i'll tell you now i was sure over 50 lbs at the track that day we met. the thing is just don't bark the turbo. let of easy(throttle) oh yeah ! i did knock off more than a second of my e. t. by removing the plate , but !!!, i did put some cushin(machine work and measuring) at the end of the rack travel. that is why i did NOT recommend you doing the same.

A non-WG housing is a disadvantage only if you have enough fuel to push the turbo past it's efficiency range. The only advantage to a non-WG housing is price.

Lower back-pressure and improved exhaust flow are other benefits. PDR sold me on the fact that their HX35 with 14cm3 turbo will spool as quick if not quicker than the WG version with my mods. In other applications, a non-wastegated turbo will likely have more lag.
