I want to change the cams in my b16. I know i need to replace the valve springs, retainers and lma's. Do the cam followers need te be replaced with new ones if i get new cams? Does anyone know how much they cost? Are cams even worth it?
stock bottom end and head, type-r intake manifold, 4-2-1 header, high flow cat and exhaust, injen intake, fuel pump, p28 with hondata dyno tuned. 155 whp
Good first post noob!
Hard hitting VTEC is never correct. From the quick search I just did, I'm in a hurry at the moment, it looks like the B18C engines cross over at 4400rpm.If you're tuning for reliability, you'll want the crossover to stay smooth instead of creating a power plateau and following spike by moving VTEC higher. If you're tuning for power, you want VTEC to be just before the low lobe starts to fall off so the power curve is nice and smooth. There's a method to the madness. My tuner is an both an ITT Tech and EFI University graduate, he knows his shizz and is very open with the theory.
If anything, leave it stock until the tuner decides it needs to be changed by looking at the dyno graph.
"It all depends on the cams..."
Do you not see that that's exactly what I'm saying? How many times do I have to say "set VTEC crossover just before the point where the low lobe falls off"?
You sound like you know garage tuners. I'm talking about real tuners who use dynos. If VTEC hits noticeably hard, the crossover point is wrong.
If you know REAL tuners, than THEY would know that tuning is more than just a "smooth crossover". You tune for your powerband, like i said, depending on the "cams" and where you want your power curve/rev range. Most bigger cams make their power UP TOP.
Secondly, ive never seen a big cam, for example, Toda C, have vtec crossover come in "smoothly" regardless of tuning. Thats a BIG cam. When vtec crosses over, you WILL feel it. I'm not a tuner, I build. But thats just common sense. Your saying that when "tuning for vtec crossover", it should come in smoothly... thats NOT the case with all engines Blanco, you should know that.
I'm finished with arguing over the f'ing vtec crossover. I know what works for ME and thats all that matters to ME.
Ya man. Try and get Skunk2 stage 3 cams to cross over smoothly. Just won't happen
Lets move on here.
If i get new cams do i need to get new cam followers (rocker arms)???
When i was building my toyota 22r the new cam required new followers, this is why i ask.
BWUAHAHAHAHAHAHAHAHAHAHAHASome lame Photoshop images for the intelligence impaired.
This is what happens when you set VTEC too high for where the low cam makes power.
This is what happens with a large cam and a proper VTEC crossover.
The jump you feel is from the power, not from the VTEC crossover itself. It's called larning, maybe ya'oughta do sum!
