Engine/Transmission (1994 - 1998) pick me a turbo

[jkidd]

the aftermarket turbine housing/wastegate set ups are not really going to increase spool up, but may help with lowering drive pressure in higher rpm and performance settings. Better places to spend $500 in my opinion. Like an exhaust brake, or airflow mods.

My setup is.........Crazy Carl's Intake horn, intake plate, homemade intake pipe to turbo. fuel plate (no idea what size because it was in there when I bought the truck). 4" exhaust to stacks.
5pd 3:54 gears
max boost I've hit was 36psi
She does smoke pretty good, but I've seen other trucks that are a lot worse.
I'm looking for quicker spool. I guess the wastegate is out of the question.
So maybe...........i could do the 50hp injectors with DV and maybe a 3k gov spring?

They have also invented their own parameters like air density percent gained instead of horsepower and torque. Basically the most bias test possible.

Umm, I hate to break it to you but they ARE making a lot more sense than most of the glitzy marketing crap about turbos. Power and boost ratings on a turbo are totally useless, they just look good to the buying public and are the true bias.

Turbos do NOT care about HP or TQ, that is a function of the fueling. Turbos live an breathe, literally, around lbs\min of air, charge air density, and charge air temp. Air density percent gained will translate directly to power gained if the fuel is present, all part of the air\fuel mixture calculation. It is impossible to gauge how much becasue it is dependent on the amount of fuel present so the discussion around power really is pointless.

Sorry should have clarified, I was talking about their intakes. http://www.bankspower.com/products/show/238/1 Banks doesn't make a full turbo for cummins only a quick turbo assembly. As for the turbo ratings then yes horse power is useless. I look for the actual turbo measurements and CFM or lb/min. hp claim for a 63mm go anywhere from 500-800 "because of our special technology".

As for the 63/68/14 I know its a standard borg unit, but with a 14 it wouldn't spool low. Ive been looking for a 63/68/12. there are a few of them for the third gens, but I cant find one for the second.

Yeah, that makes differnce.

You should be able to get one configured for a 2nd gen, basic difference will be the direction of the compressor output and how they mount the WG. The 63\68\12 should spool good and have a decent top end unti you go beyond 1:1.2 on the boost to DP ratio then it will slow down. Biggets thing with a p-pump is getting the timing and low boost fueling correct to limit smoke. If smoke is not a big deal then it is a little easier.

 

[KBurgoyne]

here is one, but it comes with a 3rd gen compressor housing and no wastegate. the 12 exhaust housing t3 flange is an $350 option total with downpipe is 1275. http://www.cumminsperformanceparts.com/s3tuwihxho.html

This is a list of the best articles and information I could find on the various turbos that I looked into. Much of the information is from common rail 5.9s, but its all there is.

There were others, but I either cant remember or couldn't find any good info.

I would call Bell Turbo. Bell is a great turbo only shop in Philomath Oregon, he will give you real world no nonsense advice about your application and use. I have 3 of his turbos and I have to tell you they are the cats meow. Great flow and low rpm spooling. Lower EGT's!!! MORE POWER!!! He is a great source of info. Bell aslo has made turbos for a few record holders, he has been building turbos for over 25 years.

Ive been looking around more. ATS has a new aurora 4000ti. 64.5/70/13 with a billet titanium compressor wheel and they added a waste gated housing. I havent seen a site yet that has the ATS turbo information correct. There are two different version of the 4000. One for the 1994-2002 second gens and another for the later trucks. The second gens are 64/70/(13,14, or 15) availible with waste gate, and a 63/70/(13/14/15) non gated for the later truck. The information for the two versions got mixed up together and in some cases mixed with the 5000s 70 psi max. The 4000 is designed for a max of 48. They also come with a 3 year 150k mile warrantee (yes limited) but still the only true turbo warrantee on the market. Thats where im leaning very heavily now.
