Ball Bearing replacement turbo

[WBacon]

Ive been thinking a bit about my other post asking about twins. If we go a different route... are there any good BB turbos available. I saw some old threads about the garrett. I like the idea. There product usually is excellent. Is there any new news about them?

I am turbo shopping and going back and forth between a Garret Powermax Stage 3 3788R 63. 5/73. 5 . 99 AR and a ED 63/68 . 70AR. Price is comparable, I am just a little worried about spooling the Stage 3 at low rpms, but the 2 probably spool the same... so the BB is most likely what I'll run.

I have heard from multiple shops to stay away from the Stage 1 and Stage 2.

I have also heard a Stage 2 . 89 AR exhaust housing will fit the Stage 3 and improve spool-up.

Have you guys heard the scuttle about the new Borg Warner EFR Turbos? They're still in development for diesel trucks as far as exhaust housing side goes but they are the absolute latest state of the art in turbo technology.

Industrial Injection and BD will both be carrying them and I would imagine High Tech Turbo will too.

I'm seriously looking into the EFR series. I just don't have the cash for triples, nor can I deal with lag from a large single.

I have heard about EFR, but $$$$$$$$$$$$

What about that new Killer B from BD, it sounds awesome if a guy isn't looking to make huge HP

 

[AH64ID]

I have looked at that, but its a 63/65/14 for a price of about $100 less than a BB water-cooled Garrett. The Garrett should spool as quick and have a better top end and lower DP due to the larger turbine and A/R. While I haven't heard it occurs on the Killer B, there are lots of reports of S300's in the 64/65 size surging badly I am not sure if the 63/65 would be the same, but they are also close in size. I do like the 5 pad thrust bearings vs 4 that are standard on a S300, but BB's are more durable. The Killer B does appear to flow about 3 lb/min more than the 3788, but thats a 4% difference and I am not sure if you would notice it, and at max flow the 3788 should have lower EGT's and DP.

Any news or thoughts on these responses. I like the garrett but it sounds like its still in the development stage?

 

[WBacon]

I just read through the install for the garrett and it bolts right to the stock exhaust elbow. Makes me think it would bolt onto the factory Jake brake since it is in the same place. Anyone use the Garrett?

 

[AH64ID]

The Garrett has been around for quite a while, so not in the development stages. Yes the Jake will bolt right up, one of the reasons I am looking at the Garrett.

I have the Garrett turbo. It's a Turbo Re-Source Stage II, which is a slightly modified Power Max 2. I love this turbo, but it I really can't compare to the stocker or else. At basically the same time I did the turbo, I did cam, IC, exhaust manifold and intake horn. I was looking to use the smallest turbo possible to make 500HP (which I think I did but I need to get on the dyno). I wanted to retain drivability and spool. To that end, this set up is fantastic. Spools at least as quick as the stocker, maybe better. I can run the smarty on 9 without problems but am using 7 now. I think the stage III would spool slightly slower than the stocker but better than a conventional of the same size.



Honestly, if I had to do it over again, I'd probably just do the ATS 4 or 5000 twins using the stocker. That really is the best of both worlds if you have the $$.

Ballpark $2500 I believe. Can't remember where I read that at. Was one of those latenight diesel shopping deals

The prices I've seen have been way more competitive than that.

Is the Borg Warner EFR a plug n' play option for our trucks, or are pipe and other plumbing mods necessary??

 

[seafish]

I though you guys might also be intersted in this turbo... .



Here is the link to the actual turbo kit ... Looks VERY interesting...



Switchblade Turbocharger --- Blaylock Turbochargers





this link is to a current turbo thread here on TDR discussing the development of the Switchblade -- Be sure to read the whole thread.

From what I can tell no. But B+D, Industrial Injection and High Tech Turbo will be able to adapt it but who knows how long.

 

[WoodChuck]

Switch Blade looks promising, now if they incororated that technology with a BB Turbo how sweet would that be?

The EFR turbos are physically larger than the stock turbos I believe, so not really a direct swap. Probably need exhaust mods or intake mods, or possibly both. And you can also opt for a water cooled version.



I'll have to go dig through the links I have saved to double check.
