I am sure you can make good power with them. Just keep in mind that
the stock pistons will need to be notched if you want to spin them.
Ask around here how far back and deep you would have to go on the
reliefs, especially if you want to mill the head or deck the block...
I would consider this mandatory if you wanted good results.

Good Luck

 

what u mean by notched?

 

With the high-lift cams, the valves might make contact with the pistons. Clay the engine and modify the valve reliefs or buy better pistons with the reliefs enlarged already. RS machines has them I think.

 

yea i was gonna clay it...you think after claying it i'll still have to notch the valve reliefs? but anywhos....can anyone give me a rough estimate on what numbers i'll be putting out...im tryin to hit the 200hp mark!

 

i would get the rs pistons for sure.

Not with magic clay. It will guarantee no piston to valve contact and you will make 200 whp with stock B16 cams.

 

I say 599 whp for sure. Every motor is diffrent if you just take a stock b20 block I dont think these cams will work. If you go with a high compression piston and these cams you should be good for a 200whp-225whp depending on your tuning. Without the pistons, assuming your vavles dont strike the piston, maybe 175whp and that a big maybe

 

175whp? i've seen stock b20vtec w/ctr cams put out more than that!

Sarcasm. It's because every setup is different. There are only about 15,395.2 factors that determine how much power your setup is going to make. Could be from 125-200whp. Chances are, it's not what you wanted to hear.
The only true answer is to dyno and find out. And then when you do dyno, don't start comparing your numbers to anyone else's because every dyno is different. How fast you go down the track is really what matters.

BTW, if you read the forum rules, you'd know that "how much whp will this make" questions aren't allowed for the reasons stated above.
