alright im kinda new to the cummins world but im learning fast. i have a friend, who is a girl, that is getting a 01 cummins with a stick. now im no newbie to diesels, i know you need guages right off before you do much. my question is what are some cheap mods i can do myself to her truck to juice it up. im good at hands on stuff so thats no problem. she wants the big exhaust and chip etc.. but her money is short. first thing im gonna due is cut out the muffler and cat and maybe add a good air filter, anybody know a good replacement? any other simple mods such as a way to add boost etc...

 

An, EZ would be good for starters. Just remeber the gauges. She'll want more power after she gets bit by the bug.

 

Start with the LP.

 

he he oh trust me she has the bug already. she used to have a 13 sec d-max so she is addicted to diesel power. she cant afford the chip right now but wants one before race season starts.

whats a good replacement lift pump?
air filter element?

 

BHAFs are pretty cheap, and will give a nice whistle. Pull the silencer ring out of the turbo too, for some more noise.

Boost elbows are an easy way of getting boost, but without a boost fooler, its gonna hurt you more than help. If the ECM sees more than ~21 psi of boost, it starts defueling.

 

Does she have a sister?!?! LOL

nah, get the gauges, check the fp then go from there. The ez will be a good cheap start.

Or she can decide what hp she wants and do it right the first time.

 

For the big exhaust I'd check out ebay, they have straight 4" for like $205 plus shipping and 5" for $250-ish.

 

bhafs? explain please

boost elbow? i know you can usually put a resistor on the boost sensors to give more boost but how much will it raise her boost with a 10k resistor. i know a cummins can handle quite a bit of boost so im not to worried

 

bhafs = big honkin air filter. Its basically a dozer air filter.

Resistor?

nah just get a box with a boost fooler and stick a boost elbow on the line on the turbo

 

i dont know the milleage yet so whats a good way to check the fuel pump? sorry for all the questions but like i said im new to cummins but trying to learn quickly. im familiar with chevs but thats a whole nother ball game. man i cant wait to get myself a cummins

 

explain this boost elbow please! is that on the wastegate lines or boost tubes?

 

got to stick a fp gauge on it. no less than 8 psi at WOT

 

The wastegates on the Cummins are mechanical. On the compressor, there will be a brass elbow. A boost elbow is exactly the same, but has a smaller orifice in it, which will hold the wastegate shut until a higher pressure is reached. There are adjustable ones on Ebay for $15, that you can adjust with an allen key.

 

ha ha ya i need one of those too

 

if you buy an ez or a tst or a comp or a box of the like it will come with a boost elbow
