What upgrades to get

Ok I just recently got a 98 12 valve with a 5 spd and am fixing to have my hands on pretty big chunk of money and will admit that i dont know much as far as what upgrades to get i have some huge filter i was told was a big honkin air filter or something and a guy i know slide my plate and housing but i didnt want to grind the plate until i got a pyro but im thinking i want to grind my plate to a #0, get 4 inch dual exhaust, a turbo, injectors, clutch, and maybe go to a 6 spd what do you think and what kinds and should i get a different intake

Welcome to the site .... what part of FL is Williston?

Before you do any modifications to the engine you need to get gauges on the truck..... That is the first step ... then you let it breath ...... need to do an intake and exhaust ..........

:agreed: Gauges first. And get that KDP tabbed!

What are your goals for this truck? What kind of HP do you want? How much money? Hundreds? A thousand? Ten thousand? We're pretty good at spending money so we can help with that. : :Thumbup:

The BHAF is good up to like 450-500HP i think so if your planning on staying below that you will be ok. What kinds of mods depends on you goals so I can't recomend much just yet. But defenatly add to your list a GSK.

Do pre-turbo. Alot more accurate. pyro, boost is all you really need but a fuel psi isn't a bad idea too.

:iagree Pre-turbo is better, it reads hotter, reacts faster, and is more acurate. Post turbo reads low by anywhere up to 300*

For 500hp its pretty easy. Add to your list a GSK, turbo and injector choices are kind of personal prefference, but I recommned atleast looking into DDP stage 3 injectors and High Tech Turbo 62/13 with the new stainles housing. Use a southbend clutch, 13" OFE should hold but if you pull the sled a lot then maybe the 13" FE but its more grabby and less streetable. Add o-rings or studs, add timing, and getting the pump bench flowed will make those levels more achievable.

You should talk to Bouncer he's in that range.

The 370s are a cheap way to make HP ... The turbo would be a good choice.... I am not a fan of duals on a Cummins because you add back pressure

370s are good cheap power, but I personally don't like them because they smoke a lot and haze at idle but if your on a budget you can't beat them.

If its a 98 5-peed then it will have 181 dv's which will flow enough to make plenty of power but if you want more and don't mind smoke 191's or laser cutswill give you more power but you pay for it with smoke and high EGTs.

HT turbos and dual exhaust are awsome. And a six speed would be great, I want one myself. For good power you need a governer spring kit so you can use some more rpm's.

If your hookin to a sled thiers only one way to go. Double Disk! And I would go with 191's thier great for the street.And for injectors Ive been running 5x.016 and there a good injector for making power but keeping it on the street.Mine are for sale if interested, just pm me if you are. And if you think you will be up on 500hp dont get a bhaf if you run hard cause mine was super clean and I still collapsed it down nearly 2 inches cause it wouldnt pull enough air. And just from personal expierence if you sled pull or run hard stck with the nv 4500 . Just my thoughts.
