Questions about Camshafts

[superkoh]

can ask all the gurus here, what's better on either b18c-r & b20, please give in terms of Durability come first.

1. Jun stage 3
2. skunk2 stage 3
3. Toda C
4. BuddyClub Spec V
5. Crower Stage 2

what valve spring retainer to go along? Anybody using supertek? Any comment?
And cam gear. KUDOS

To start with, what is your application?

2- Whats your compression?

3- What RPM are you planning on revving to?

The supertech is the same as any other as long as you match the lift of the cam to the valve spring and keep the seat pressure reasonable with the springs.

Cam gears, I would use the same brand as the cams itself rather than mix and matching.

i don't plan to rev up to 11k or so-ever. The most also would be 9.5k, daily driven with occasionally up to 9k.

doing up a b18c-r

if i were to take buddyclub i need to take its cam gear, which is more advisable since its from the same manufacturer? vice versa

the cheapest way or the easy money way...???
how many horse do u expected & the most important is, which management u will consider 1st...??

can just pass a few spec for u for reference...

Not a lot of cams would make power up that high RPM. When talking about reliability, any engine would get stressed revving up to that point but let the others chime in regarding this.

Toda C would be my choice for ocassional high rev based on your list.

But my personal choice for a daily driven application, I would settle with BC 3 cams (fat midrange) or skunk2 tuner series stage 2 (nice top end). It works well with CR of 11.5-11.8:1. But ofcourse everything has to be tuned on a management system like Jin said.

all the cam above can let u get through 200 horse on wheel..
the higher duration the cam go the higher the power band at. the more lift got the more power can get by without reving so high up.
but one thing i advice is to used bak the stock cam pulley and mod it like adjustable one...toda cam pulley will worn out oso...aerospeed that i used now same...it will makan timing belt...

if u seek a builder for u pls PM me....i got a fren can do all that for u ....

oh yeah u need to have a high compression piston to run good on it....bcoz the higher duration open the shorter the compression stroke duration..that y u need high dome piston to compress the air fuel mixture...
the best ECU for ur upgrade i recommand is hondata...coz nothing run honda engine best then honda ecu... cheerS~~~~

most of us here encounter the prob of higher CR bout 12-12.7.... after the cam & head done... will get very nice figure of power when pump will V-Power(to prevent knocking), but not really suit the others petrol... spark plug using 8.

i always pump petronas.

i might go for jun3 or skunk2 stage 3, if not i'll go for my builder recommendation, buddyclub spec v.

but about the cam gear, use a adjustable one?

okie... as far as i know, if wan huge ponies at high revving points, the cam must higher & the lobes must b high as well...
