ready for new turbo..what to get?

[jaynes]

So here's another post! I'm ready for a turbo upgrade. I have a couple of options, well a few actually. I've researched all of these but am unsure of which I should take.



1. I can go to High Tech turbo, but I don't know whether to get the Stage III upgrade from a 56mm wheel to a 60mm wheel for the H1C upgrade, or go with the HX-35 upgrade from a 56mm to a 58mm,compressor housing included. Both from High Tech Turbo, and both used in conjunction with a 16cm2 housing. Downside, if I did that I would want to replace the bushings and stuff inside the shaft housing, or whatever it's called, and I don't know how to do that, or where to get rebuild kits.



2. Go to Piers and just purchase a PDR HX-35 for for twice as much (you get what you pay for, so it's probably twice as good... !) than I would for the HX-35/16cm2 option from High Tech, and still have to rebuilt the aformentioned items, and still have to spend $145-150 on an exhuast housing.



3. Go to Piers and send them my turbo, have them rebuild the inner guts, and have them machine out my compressor housing to the specs of an HX-35, with pin wheel and all, and hang a 16cm2 housing on it to boot, for about the same price as just buying the standard PDR HX-35. Downside, i'd have to send my turbo out. Not so bad side, Daniel was gracious enough to offer me a spare until I got my new one back.



SOOO, I don't know what to do . Can somebody maybe point me in the right direction? I know that was long, and I'm sorry. I just don't want to make a mistake that costs $$$, ya dig? Thanks guys!!

i recently put the 60mm wheel from htt in my h1c. very, very happy with it. especially due to the cost to performance ratio. i did the machining myself, so got out of it pretty cheap. as far as putting new bushings in, i took apart a turbo that was worn out not too long ago and there really isn't much to them in there. i think i counted 8 individual parts (including the shaft). i would think that htt could supply a kit for that task. anyway, thats my input.

Thats cool, are you running a 16cm2 housing with it too? Was it hard to replace the internal parts for the rebuild? Noticible gain in performance? Does it whine louder?!



jaynes

 

[swankmetal]

nope, i'm running a heavily ported 12. i'm at 6000' though. i have to, to get any kind of spool. the turbo i took apart didn't go back together. it was pretty shot and i didn't have a rebuild kit. i just realised that there isn't much to 'em. IOW, i wouldn't hesitate to rebuild one if i had to. the performance gains are: 100*+ cruise temp reduction, much more efficient at 40 psi, and a couple others. before the wheel change, i could hit 1600* before the top of 4th. now i can pull well into 5th and only see 1450*. and by more efficient at 40 psi, i mean that with the stock wheel at 40 psi i was seeing 75 PSI of exhaust pressure, and with the 60mm, i only see about 47-48 psi of exhaust pressure. much happier with those #'s.

Watch out

Just a heads up jaynes; watch out 'cause 'ol Bills' gonna see this and tell ya to go to a junk yard and rob a CAT, or go spend a bazillion on a new 10'' turbo with 100psi cabilities. :-laf



In the end the choice is up to you, it looks like you've checked out your options, the only thing that I'll say is this, when I got mine I already had my 3'' BD exhaust brake and shortened 3'' downpipe to accomadate. Looking back, even though it is more $$ I would of gone 4''. Although I can't live without my exhaust brake, so I'd have to get a remote mount, that would've been even more$$$. So I guess what I'm saying is that you can turn your fuel up gradually and work up to a 4''.



I guess that you should just get the 4''



BTW I couldn't be happier with my PDR HX-35

 

[jaynes]

Ok well here's another important factor I forgot to mention: I don't pull anything. . not a darned thing. The heaviest load i've pulled was a 12ft Uhaul trailer! :-laf . So I don't need all that umph, I just want it to be quicker on the throttle, perfom better on the highway, and in town, be faster on spool up, less egts (i will know those soon enough) and of course, whine louder. Does that change which options I should look at?



jaynes

 

[swankmetal]

oh yeah. i forgot to mention that it sounds like my truck is getting ready for take-off now.

Jaynes,



Do you have plans to increase your fuel? I had gotten an HX-35 a year ago that I was going to put on my truck. I never got around to it until now. I just put PODs on and Greenleaf modified my pump. Now I can peg my pyro if I don't watch it, so more air and bigger exhaust are my next steps. I'm going send it to HTT to work over. Something that spins that fast needs a better mechanic than me to check it out.



So if you are not planning on tweaking other areas, then bigger might not be the answer for you. Just something to consider. Good luck!

The issue with rebuilding an H1C yourself is the balance may be off when you're done... the H1C is balanced by Holset as an assembly..... so it's possible it will be off a little afterward. But if HTT or some other turbo shop does the job they'll balance it back again.

The HX35 is balanced by the individual components. So if you do a whheel upgrade afterward, it will stay balanced.

That said, we did an HTT upgrade with the 60 mm high flow wheel and housing on my son's WH1C on his 94... came out fine as far as we can tell.

Other than balancing, rebuilding a turbo is easy... and you can get a kit from anyplace that deals with Holset parts. I have a kit for an H1C... cost me about $80 2 years ago.

From all that I have read on this and other forums is the two turbos will pretty much perform the same after upgrades with the same compressor wheels.

Good luck.

I swear we must think alike or know each other too much. Before I got to your post Chris, I was already thinking this. So here goes, jaynes you gotta have some good medium to heavy duty junkyards near ya ???? Your in the Missouri!!! IMO, we all start out saying, "I'm only looking for a little more umph, throttle response, performance" etc. When actually we start down that slope of bombing. Once we fill that power, we gotta have more. So I say forget about a 35. Get bigger to begin with. Why pay twice, when in the end you're gonna want something bigger. Wish I would've gone bigger when I had the cash. As far as junkyards, sometimes you can find a really decent turbo on a core motor. You can find hx35-12's from industrial 5. 9's, hx40-16w (if you're lucky), hx40-18w both from the C-series 8. 3L Cummins. The B1 turbo version can be found on a Cat 3126, or a smaller B1 which is between a 35 and a 40 is on a Cat 3116. One could find one of these turbo's and still have some of that cash left over for a set of injectors or the like. This is what I'm looking at. Dieselman359-Chris, I'll be having words with you at the dyno event the 19th brother.

just like there are dozens of HX40 part numbers, there are TONS of S300's out there... you're not going to just pull a stock Schwitzer S300 off a truck and have a "B1" or an "HTB2"... once it's bolted on, it'll LOOK the same, but the wheels are totally different.



I've been down those roads

 

[jaynes]

I do want to turn up my fuel alittle, maybe add some injectors down the road... so should I go for the stage III 60mm wheel and housing with a 16cm2 upgrade for the H1C? Will having the extra air hurt me when my fuel isn't turned up?



jaynes

 

[Forrest Nearing]

won't hurt a bit

 

[JLEONARD]

Jaynes, If you go that way I will be interested in your results as I'm working on a frankenturbo mod for mine. I'll probably go with the 58mm wheel though... but one never knows.

Jay

 

[Greenleaf]

I had to remove my PDR 58 mm unit from my new HX35. Wasn't cooling enough with the 16 housing and short 4" exhaust, aFe/ASA intake. I'd go with HTT and the 60mm stage three 35 turbo. Bolt yourself on a 16 or 18. 5 and you'll be happy.



My HTT stage three with 21 housing really whistles and that's just at slow idle speed. I'm luv'n it, so far.

[JLEONARD]

Scott,

Better send your turbo back... ...

I just read that HTT has a 61 mm super-duper flow stage IV wheel with an extra loud dixie-whistle housing... . :-laf :-laf

Coudn't help it!

Jay

 

[Greenleaf]

I just got off the phone with them... . it whistles "Dixie" as you row up through the gears.
