any particular reason?

I've ran a D-tech 65/62/12 in a number of different configurations over the past several years. For about a year it was a single. Then over the next couple of years, it was sitting on top of several different primaries.
Runs good as single with 5x12s. Set it at 40-42psi, and you won't likely have any problems with it. That's the good. The bad is.... when you start to push it any harder, some issues may arise. The standard thrust bearing doesn't hold up so well to high drive pressures. Doesn't take much wear before the compressor wheel can come forward and smack the front cover, $$$$. And, the arm holding the wastegate pucks can't take much drive pressure either. Too much, and it will bend back leaving the wastegate hanging open. Be aware though, some of the other major manufacturers have had the same problems, but most have since beefed their turbos up. Not sure if D-tech has. D-tech comments on how their wastegate flows more, well it doesn't really. Mine came with ~12mm ports, which is more or less the same as a lot of the other turbos. But the pucks are big enough to drill out a little bigger. Be aware again, bigger ports mean more pressure on the wastegate arm. And more of a chance that it'll bend. Mine works great now, but I'm not sure that it still can be called a D-tech. It has a different compressor wheel and a STEEL 360 thrust bearing. I milled out the whole wastegate area. Enlarged the ports to flow more than twice as much as the original ports. Oversize Inconel pucks with a heavy duty wastegate arm. Right now I'd call it a pretty awesome turbo. Even with the compounds hitting 90psi+ boost, the drive pressures are 1 to 1, due to all of the wastegate work. The D-techs are pretty much worth what they costs. If you want a better turbo, then you'll need to spend more. Personally, I'd go for one of JKidd's 63/68/12s with a 360 thrust bearing. |
Ok sweet thanks for all the replys how much hp you think I'd be puttin down with the 5x12s and the II 62/65/14
|
crappy question, my guess is 375-425 but its nothing more than a guess till you put the truck on the rollers.

My 62/65/14 supported 487 waaaay overfueled. I like it, good turbo, got mine from John at Majestic turbo, he's a good guy. 360deg bearing and everything.

Jason- was the 62 on the 89
---AutoMerged DoublePost--- 89 dodge that is |

our 63/68/12 has a 16-17mm port and we can enlarge it for $50 to flow more.
