I was wondering if you guys thought that taking a 209,000 mile engine and rebuilding it for performance, but not a total rebuild, is worth it. I want to build it up for performance cam, and other performance parts. Also want to add nitrous, and wonder if my engine could handle it, and what I would need to make it handle it. I know I would probably need forged pistons, but not sure what else.
I'm just wondering if it's worth it to slightly rebuild and button it up, and then add nitrous per say. I'm not sure if the engine will be able to take it.
O, i get it, i dont see why it couldnt take a 50 shot... even with all of the miles I've got on mine, as long as you took the normal precautions, it probably wouldnt be a big deal. I really havent heard of many people using nitrous on the 22r, and I hope to, but I want to get some feedback first
unless you want to do some good expensive racing at the drag strip, which these trucks were not made to do, id look at other options. if youve looked at all the other options and still want to do it then your stock engine will need a minor rebuild. you'll need at least forged pistons, fuel pump, cam, header, exhaust, and some good tuning on a dyno if youre doing a wet kit and going for a big shot. google search Phase Change racing for a nitrous tech god.

I would rebiuld it totally. Why do a half job and end up with problems later. You might could get away with a half job, but why go so far and chance it. I have HEARD that a stock engine can handle a 125 shot. I would go with forged pistons though. And use progressive stage system that way all the shock isn't all at once
Yeah, I want to go all motor, but was thinking about nitrous to give it a lil more umph. I'm not really sure that all motor would give me the kind of power I desire, plus nitrous is easier then a turbo install, so I prefer this.

Of course I'll probably do it in a stage system. If I could I'd rebuild then entire thing and add the performance with the all new parts, but it's an issue of money. I was just basically wondering if it would be worth it with the high mileage engine I have.
Oh, I was also wondering how big to go on exhaust? Most of the exhausts I've seen for these trucks are 2 1/2 in. or so. I want to do a custom 2 1/2 to 4 inch, but wonder if this will give me more performance than just the 2 1/2, or if it will just be a waste of money.
2.5 is ultimate for hp, dont expect to have much tq though. just remember you never have to refill a turbo and its legal on the street.

well in the long run, a turbo or sc pays for itself. great no one will ever know that you use a power adder to get a 14 sec time slip. Start practicing the phase "sorry i cant race, my bottle is empty" or "well i would be faster if..." you can go talk to your local ricer group to learn the best variances of these sayings.
all im saying is if youre going to do it, do it right. ie: use both nitrous and a turbo!
