I am sure this has been asked before. I have a 06 LBZ and not sure which one to go with. My goal is about 500+hp at the rear wheels. What is the different between the two? What kit is the best Suncoast,ATS or PPE? What about precision converters? Is the down pipe worth the $$$? Is Mike L's c3 oiler a must with this set up? I use the truck for work and would like to go the track a little(some street racing to). What converter is best for this purpose? Any other info would be helpful.

Thanks for your time!

I'd say go the strongest possible which i believe is the IV.

I may be mistaken so let another member confirm or set ya straight on this but i believe the c3 oiler was for the 5 speed allison's because they were changed on the 6 speeds.

When i do my trans im going balls to the wall on it because i dont want to have to go in and do it again later if plans change or whatever and i end up wanting more power. Might as well just drop the money on it once and be done with it.

If you plan for the track with stock Duramax internals Suncoast III be plenty but I go with the IV system. Additional clutch pack added is one thing I believe. As for converter I have Suncoast 1056 and does extremely well. Holds great at least Nick from DuramaxTuner said that today checking things out and fine tuning. Mike L converters are good too from the reading. And for the ATS to certain things I here is good. But can only say Suncoast IV and 1056 converter for me is pretty sweet. 5000 miles on it and running good.

Why only 500? With a lift pump and tuning you can be over 540. If you truly plan to keep the stock turbo, CP3, ect under the hood the Stage III built correctly would be plenty for you. If you think that you might, maybe, someday consider upgrading anything under the hood I would recommend the Stage IV so that you are ready to handle any future upgrades. I prefer the Precision Industries converters and for your application the ML series would suit you very well, and save you $200 over the SC 1056.

Thanks for the info so far fella's! But any other info would be great. What about the downpipe upgrade and the c3 oiler are they needed for my set up?

Thanks,again

As I said I prefer Precision Industries converters (there is another converter company with Precision in the name that I wouldn't recommend).

In my opinion the downpipe is not worth the money, not worthless - just not worth ~$200 performance wise. But I do know a guy about to sell a used one - depending on his price it may be worth it then - contact DrHolliday.

I prefer the SC kit - you can still get the old school Stage IV if you prefer the tried and proven performer, or you can go with their new GMax stuff which I like alot (just did another one 2 days ago). The PPE Stage 5 kit is basically a SunCoast Stage IV knockoff using Alto power packs (same clutches the SC IV used) and TransGo mods. Until very recently there has been a clearance issue on some of the Alto power packs and if the DIY tranny builder gets a kit and doesn't have the spare parts to fix the clearance he will end up with a trans that won't last as long as it could. The SC kit is much better IMO for the IDY trans builder. ATS has a great warranty on their pre-built transmissions, not sure how they do on their kits when you install them yourself; I would rather have and build transmissions that don't have problems than have and need a good warranty. Most reputable SunCoast builders will warranty the trans anyway.

Mike L's C3 oiler sprays continuous oil on the C3 clutches which go through 3 heat cycles during each pass. It helps to cool and lubricate them between each use and will help them last a bit longer. With the GMax kit I think it would be an even better idea since they don't have oil passages through the clutches or steels.

What is the GMax kit? What about ATS'S manifolds? Are those better than the downpipe or are both a good idea?

Thanks

i would shop around for builders not necessarily for trans kits. that is unless your going to put it in yourself. the best transmissions wont hold up to anything unless their built right.

The manifolds are a really nice piece. Flow a lot more than stock which will really help out your turbo spool up, lower drive pressure, and lower EGTs. The cast manifolds are proving to be a really reliable set up.

As for your tranny, the ATS kit was designed to be a DIY kit. There is a couple stages depending on what you want to do and what year your truck is (5 speed or 6 speed). There are quite a few of the kits running around with great success. It comes with C1-C4 ATS clutches and laser cut steels, pump kit, shift kit, and a Five Star Converter. The Stage 2 kit is good to 600 HP.

I'd do gmax6 and I would do the down pipe, we loged egt on the dyno and saw a 200 deg drop

Mike L Stage III works perfect for me. I run the PPE 350 tune daily and the tranny works perfect!

The GMax kit is SunCoast's new kit that "supersedes" the Stage IV. It has single sided carbonite C3 and C4 clutches similar to the single sided C1's that the Stage IV kits always had. You can also still get the older Stage IV kit if you prefer it.

I would like to see a picture of the ATS manifold cut in half half length ways to see the internal flow characteristics. Judging from the looks of the outside I prefer the ProFab manifolds and up-pipes and think they will flow better; but until I see a set of the ATS manifolds in person or a cut away I won't say that I know one is better. I have seen a cut away of the ProFab's, had a few sets in my hands, installed a few sets and seen the results of them. They will lower peak EGTs and reduce drive pressure which will help the engine breathe more freely and the turbo run more effeciently - making more power.

Who's torque converter does ppe use?

Thanks othrgrl for the pic's and info! That really helps me understand all this better. Now I just need the cash to do it. As Dave Ramsey says "if u don't have cash u can't afford it". I will be paying green cash for ALL up grades!

Who's torque converter does ppe use?

Ask Dan at PPE.:D

Do the IV there always comes a time where 500 isn't enough :cool:

Who's torque converter does ppe use?


Precision Industries out of TN.

Ask Dan at PPE.:D

Mike what is your opinion on this? Is Stage 3 plenty for a truck with stock internals just lift pump and tuning making 510-540 rwhp?

From what I have read/been told it shouldn't be a problem as long as the right person builds it. Heck Trent Nell was making a couple hundred more then that on his stage 3!

My stage 3 does well at high hp but I do not advertise it as such. I don't recommend it for anything over 500 hp. Yes Trent ran his to 11.00 without a problem. Trent even built it himself.:cool:
It's not the Precision or Suncoast converter or the Alto clutches or the Transgo shift kit. These great products all help make it happen. It's the little things that you do that set these trucks apart and make them live.
Remember guys; it's not how long it is, it's the cute way you get on and off that turns the ladys on.:cool::D

I'd sure like to meet you sometime Mike. You sound like your quite a good fellow. I've never heard that saying before, It's a good one.

mike L, what do you think about the gmax-6 kit for the 06 lbz d-max??? do you think it will hold 500rwhp?? thanks justin
