 Subject: Good Idea???

Message:
First of all, I have a 2001 Dakota 4.7, 3.92 lsd, rc, with flowmaster exhaust, autolite 3923's, 180 t-stat, homebrew intake and traction bars. I have BIG plans coming up within the next year or two (or three), but I wanted to see which order I should do them. I'd like to take a week and do it all at once but I want yall's opinions. I want to add nitrous (75 shot), 72 mm throttle body (since I'll have nitrous), HO intake, 218 krc cams (i read these work well with nitrous), and send off my pcm to get it flashed while my truck is down for the other mods. I wish I could do all the work myself, but I will probably have to get some help from the local mechanics since I'm no expert. I know all of this will make my truck incredibly fast (in my opinion), but is there anything else that should be done first in order to run all of this and not mess up other parts of the engine(do i need heads [worked or new], pistons, headers, 24 lbs injectors, clutch, etc.) I'd like to know what needs to be done to get the most out of my truck for each mod.
Thanks
Jason

Wouldn't be a bad idea to contact Marty at krcperformance.com for some expert advice.
What is your budget? If it is high I'd focus on some of the higher priced bolt-ons and suspension that actually have provided gains before going with nitrous. The 218 cams are for higher rpms so be careful how you set up your engine so as not to lose all of your low end power.

Ok, I dont' really have a budget. I was going to figure out what I wanted, and then save up until I can do it. If there is something out there that is high priced but is the best to use, then I'll just wait a little longer to buy it.
Now that you mention it, I think the 218 would be too high end. Maybe I'll go with the 212, I'll have to check on that. The reason I was going to do nitrous at the same time as everything else is because I've heard that the cams ran better with it (or so it seemed). So I can wait on that. But everything else, can I put everything listed (tb, cams (possibly 212 now), ho intake, pcm flash) on without other modifications. The stock heads and stock injectors are ok? I still need to adjust my tps, buy some headers and get true duals (instead of my one pipe with the flomaster on it), and remove a cat or two (if possible). Thanks for the help, anyone else with some input.

For throttle body i'd stick with a 70mm. It'll provide all the flow you'll really ever need.
The Kenne Bell flash is probably your best bet right now. Do your other mods first and inquire within Kenne Bell on what they might be able to do for you.
As far as cams go...I don't have any yet. I'm holding out for non-regrinds from crower, comp, or who ever. The krccams are getting some pretty good reveiws though so its your call. You just need to decide where you want the power.
The HO intake is supposed pretty useless from what many have said. Check out hughesengines.com and check out their intake. It's a modified non-ho intake with shorter runners. I haven't heard from anyone who has tried it.
Stock injectors are fine for now. You could have the exhaust port opened up on your stock heads. Find DemonDakota on these boards and ask him about it. He's had it done. I think he's been satisfied thus far.
Go to GSmotorsports.com for a true dual exhaust that makes like 14rwhp. Kinda pricey but h.p. isn't cheap.
Hold off on headers until someone comes up with headers that are actually worth the money. Right now none do much and are way to much money to be cost-effective.
If you want an air intake that is expensive but works and they have dyno-sheets for the 4.7L check out roar, inc. They claim 13rwhp with their itake. But it too is pretty pricey.

I'm confused why you say "72mm TB,since you'll have nitrous". Why the need for a larger TB when nitrous is an oxygen adder ?

Sorry about that, I was gettin ahead of myself and thinking about nitrous while I was typing. The last couple of things I wanted to do was add the shaker hood and possibly a supercharger (instead of nitrous, I want to do more research before making up my mind). I think a supercharger is a lot higher than what I want to spend any time soon. I guess I also need to research the ho intake more too since you said it didn't show improvement.
So this is what I plan to do for now: 72mm (or 70mm if i decide to never get a supercharger), krc 206 or 212 cams, questionable ho intake (i've seen a few posts that showed improvement with this), pcm flash for sure when I get more mods done, and now possible opening the exhaust port (that's new to me so I'll have to price it and check some posts). Thanks a lot for all the info. If you have anything to add or take away I'm open to suggestions. Just to let you know, I'm shooting to be in the 12's very soon.
Thanks

Just don't forget about your suspension. You may want a better clutch as well like a center force if you are shooting for 12's.
If this is going to be a truck built for speed...which it sounds like, I'd go ahead and get the ho intake. It'll probably help you in the higher rpms.
If you plan on running nitrous i'd look into strengthening the engine itself. For longevity purposes. Otherwise your engines life could possibly be cut down some.
Don't forget about your brakes either. If yer going to haul a$$ you've got to be able to stop too. I'd look into an upgrade on that.

Thanks a lot CThomp. I appreciate all of your information. I'll write down the suspension and clutch so I can research them. Now, I've heard that removing the clutch fan and replacing the the belt with a smaller belt helps out. Should I do that or will I need it when I get faster (or a new clutch)? Also, I haven't heard much about the suspension on here, what about the suspension will help?

That HO intake should be worth a few hp in the upper revs. The shorter belt isn't used to bypass the clutch fan, that would eliminate your water pump. It's used to bypass the AC, usually just for drag strip runs. If you take off the clutch fan you might want to think about setting up your electric fan to come on a bit earlier.

As far as suspension goes, you really just want to tighten it up. You've already got traction bars. Get some better shocks. I'm running KYB Monomax's. There are lots of good shocks out there. There are some crappy ones to so do the research. Tirerack.com generally carries quality parts. You may want to look in to a drop kit. This will hold you closer to the ground. Some kits are better than others when it comes to drag racing though so do the research. Anti-sway bars as well. Hellwig, Hotchkis, and Quickor are all good ones. The quickors you have to get directly from the manufacturer.
Alot of people take off the clutch fan all together. Some replace it with an electric fan and some don't replace it at all. You'll find threads in past posts on the topic.
