Upgrades 99 cummins??
 

I have a 99 cummins with 200,000 miles on it the only upgrade is magnaflow 4 inch from turbo back. I just bought Glowshift gauges to watch my boost, egt, and fuel pressure. My truck has an auto trans so im wondering if i should get a new trans before adding power or try and upgrade the stock trans before adding power. If i was going to add power should i add first? I have been thinking hard about the SMARTY because i live in upstate ny and i like the 3 cyl warm up that that offers. Thanks:humm:

what do you do with your truck?
how much power do you want?

Well i haul firewood just in the bed a few times a week. I would like to go for the compound turbo set up and would like to shot for a 500-550 horsepower. I use the truck as a driver but with like to pull at the local fairs

Hey how do you like your glowshift gauges? havnt get mine hooked up yet.

You can get 500 hp with a single and some 150hp injectors. my setup made 488. But if you plan on towing and hauling a set of compounds will do wonders. Do you have an aftermarket lift pump? If not do that upgrade the trans at least billet input, torque converter, a good valvebody. Then start adding power to the truck. The trans with good parts will make a huge difference in the feel of the truck. You can get the high idle for your truck by going to the dealer and reflashing the computer

yea i like the glowshift for the money they are not bad.. make sure to use a isolator on fuel sender they wont hold up to the pulse of the fuel. everything else quad pretty much covered. like he said fuel system first. i wouldnt do a smarty it is better for 3rd gens.

So i should work on the trans first then add power? when I get done with the trans what should i do for power?

Trans first,that will be the most expensive part.You can go with a Goerend,Suncoast or a DTT trans,Basicly you pick the one that fits your needs,500 hp a billet input and out put shaft, good torque converter.Power Start with A good lift pump Airdog FASS or MITUSA then a power box like a edge or adrenaline then a turbo (single or compound) then injectors a NOS intake or Water Meth Kit.Please give a price quote when you are ready to buy, on the site you will save money this way.:U: Good luck with your build.

Yeah the trans is not going to take 500hp. A lift pump and trans should be first the lift pump over the trans. After both of them are done a edge comp. After that you need to decide if you want single turbo or compounds. Compounds would be cleaner than a single but power is possible either way. I will let you know what I think of my setup when done. my s300 62/71/14 over a (not sure the specs on what is sitting at the shop) with 200hp injectors. The 200's and my single were 532. But I would not use them for towing anything heavy I had to tow my dads 04 home on a goosneck and the egt's can get warm pulling up hills. had to back out not enough air.

Thanks so much! I didnt really think about the airdog cause i didnt know what it was but i keep seeing it one every turned up truck, im going to meet with upstatedieselperformance.com on fri. to get my gauges installed so i guess ill start looking for an airdog. should i go for the 100 or the 150? and should i deff. get airdog or a cheaper one?

get the 150 and the lift pump not a place to be cheap and make sure to send in the warranty stuff
