What is the biggest cam I can run on a B16a2 (stock internals)? Idle factor doesn't matter. Will Toda stage 3 work or too little PtV?

 

I'm pretty sure TODA VTEC KILLER cams have the longest duration and largest lift. But why are you wanting to run a huge cam with stock internals?

 

It's just a weekend car I want to beat on and I love hearing a big cam idle.

 

Stage III cams on a stock engine = waste, you don't have the compression for them. Same goes for stage II cams like Toda or Skunk2, they are designed to operate well with compression 0f 11.5:1 and higher

Stage I cams are made for stock or mild engines

 

really? thats good to know

 

So He needs to find out what cams work the best for stock internals. Skunk2's or CTR's?

 

deetz true just put gsr or type r thats the safest i think

 

ITR is the biggest cam you should use. Running some ungodly lumpy, aggressive cam would be a total waste of time and money. You can't just slap in a set of big cams and expect miracles. The rest of the setup must compliment your choice

 

yeah i wouldnt put anything bigger than ITR/CTR cams on stock valvetrain. anything bigger is just asking for something to go wrong. also a waste of money if you can't REV them high enough to make the POWER out of them.

Anything stage 2 or higher will mushroom your valves if you don't have an upgraded valve train. Trust me, I know from first hand experience...the person that had the motor swap I have now had been running stage 2 cams w/o an upgraded valve train. When I went to put in the motor, I checked the head over and this mistake ended up costing me some $$ for a whole new valve train. :/

That is the answer I am looking for. I could care less about the power.
