cams?? need help

[marshall12395]

im in abit of a pinch. so i wanna chance my cams in my b18c type r. im upgradeding my valve train, and on my car i have headers 421, 2 and half exhaust. so here my queston what kind of cams should i put most of my parts are skunk 2 so i wanna stay with them. what would be the best cams for my setup??

It really depends on how much power you want out of the car. Set a power goal and take a peak at some all motor dyno sheets to figure out which combination of parts will net you the best results. These engines have been built thousands of times and the information is out there.

For what it's worth, I have not heard good things about Skunk2 valvetrain.

i wanna get the max power for a daily driver. just not sure what size of cams my car can take

 

[Matts96HB]

If its a daily driver, I personally wouldn't want to mess with anything that required changing the stock springs and retainers. It just doesn't make me comfortable on something that I need to rely on. But to each his own.

Skunk2 Pro2 and Pro3 seem to be the choice for most people with high hp all motor setups. I'd probably go with a set of those if you must.

you dont think it will be a reliable car by doing this

 

[Matts96HB]

It might be. It really depends on how well it is put together. I said that personally I would not put springs and retainers in something that I have to drive daily. I have experience with BC springs and retainers in my turbo'd LS and I was always fighting timing belt slack and tension.

 

[marshall12395]

ok but they say with bigger cams these should be upgraged. and i wouldnt really say its a daily drive its just a car i take at night to go cruising with buds lol. you know any other mods i can put for more hp???

 

[Matts96HB]

Considering it is a Type R engine, the cylinder head already flows pretty well. But, there's always room for improvement. If you are trying to get as much as possible out of the engine while staying all motor, its going to get expensive. You have a lot of options:

Intake manifold
Exhaust
Intake
Cams, valvetrain
Larger diameter valves
High compression pistons (though your engine already has a pretty high CR)
Head work (porting, polishing, etc)
Most importantly - a tune to go with all or virtually any combination of these parts

Like I said before, simply throwing parts at it will not yield the best results. Research and a well planned build will net the best results, and end up being the least expensive route in the end.

The farther you build the engine in any direction, the less reliable it will be. The harder you run the engine, the less reliable it will be.

Any modification beyond stock, the tradeoff is always reliability - be it driveability, dependability or longevity (to include increased maintenance requirements). Also affected is fuel economy or lack thereof.

There are 3 basic questions: 1) How fast do you want to go? 2) How much money are you willing to spend? 3) What are you willing to sacrifice in terms or reliability? (driveability, dependability, longevity & maintenance requirements)

lets just say it wont be a car il be traveling in and doing long trips. its a car i just wanna have fun with on the streets and track.money wise what ever it takes to do the mods i wanna do. you think it wont be a reliable car. and how much more maintenance will have to be done. i have heard of people doing this kinda work and beeting theres cars for 3-4 years and never having a problem

I have no way of ultimately knowing how reliable your build will be. Good luck with it. Relative to a stock build, it's lifecycle and maintenance will be a function of how hard you squeeze the lemon.
