you'll crack a piston before you bend a rod in an lbz. I'd like to know why ppe wants so much for that kit also.

I think the ppe kit comes with manifolds, up-pipes, intercooler ,twin kit and all .

Welcome! Remember......you wont know until you ask:thumb:. There are a few vendors on here with twin setups. A couple being Trent Nell(Extreme Prejudice Racing) and Henry(Creatures of the Night Performance). There are a ton of guys running twins with stock internals but the right tuning is key.

Have you thought about just doing a large single? Seems like stock motors last longer on large singles than they do with twins.

If you really want twins, a good budget twin kit is throwing an s475 or s480 on top of your stock turbo. These kits are a lot cheaper.

ALso both turbo's are Ball Bearing (usually double the price of the turbo's most other companies use which are journal bearing).

You really need to look at what you getting for your $$$'s. Yes the kit is expensive but when you add all that you get in our twin turbo "Package" and how expensive the turbos we use are you will see you are getting a lot for you $$$'s.

Not to knock on Dans product or actually PPE's product... But really you do need to look at what your getting for the money. Yea the PPE kit overs all the bases, but let's think economical. How much does the PPE "race" intake cost? $600. Now let's think about what it is... It's an LB7 bridge with a 3" tube welded to it. I can weld a tube to a LB7 bridge for $30. Why does it cost $600?
Furthermore, the Intercooler is not necessarily needed. Many people run stock CAC's with no EGT problems at some pretty high power. In my honest (CONSUMER) opinion, one of these companies needs to sack up and realize that they have broken even on the initial costs of starting their company. With that, they need to stop playing this dollar game. Duramax performance hasn't been around for a long time so cost is expensive yayayayayayaya I've heard it. But really guys. When is this rape game going to end? It's been 10 years now. Why is there such thing as a $600 piece of modified OEM material with a 3" tube welded to it?! It's a disgrace.

I agree with the prices needing to come down on these parts in general! I mean the rods are crazy!!!!!! You mean to tell me it costs 10x as much money to build dmax rods as a set for a sbc or bbc?????? Give me a break

A little curious about some of the pricing myself. Something's are very reasonable... Others,not so much.

I bent my rods and the pistons were perfect when I tore it down. I think its all a luck of the draw and tuning with the pistons.

Go price a 47r and a 40r charger, they alone are about 30/40% of the cost.

Yes, some of the ppe prices are retarded! The turbo kit prices are high but the badass Garrett turbos Are not cheap either! I need to find a 4202r that won't cost me an arm anda leg. From my extensive knowledge that I have acquired over the years I can say a built motor with a decent sized single will have you making sweet love to your truck. No twins for me! Yo can run 10's with that 4202r by itself

I dont agree with you too often, but this is one time I do.

There has to be a breaking point. I understand the high costs of some of the stuff. But a majority of it is absolutely overpriced. I think that it is so much so, that it hurts the sport. People sell off and get out of the diesel performance world and go to the gasser side just because of the Hugh prices.
If the prices were cheaper, you would sell more parts so I don't think you would lose profits.

Just so you get an idea.... Mike (veeate) has a crew can short bed, and went 11.7 in the 1/4 with his LMM. That puts the truck around 700 or so to the wheels. 100%stock motor.

Its not 100% stock...not even close. ;)

.....and also, no insult intended, but his shortblock wont last long at those levels, no matter what anyone else thinks. Dont fool yourself into believing these engines are bulletproof, even with good tuning. They arent. Those shops posting threads of stock motors over 700hp are doing everyone a huge disservice. Makes me think they are just preying on the uninformed.

Sp44d -- you're on the right track, wanting to build the shortblock first. A set of Carillos or Crowers are a good start, along with headstuds. Maybe look into a set of cut LB7 pistons while you're in there. Balance the rotating assembly, too. Make sure you have a good shop do all the work.
Then you have dual CP3s, larger injecetors and whatever set of twins you want to buy. Have fun. This is an addicting hobby. :)

I dont know for sure as I never had it dyno'd but comparing it to other trucks ive been in and drove id have to say it was around the 650-700 area

Pretty sure pat means 100% stock internally, which im sure wont last forever but i dont pound on my truck very often. According to ''duramax math'' puts me around 750rwhp, guess we will find out at ts.:D
