Honda Prelude Forum

I'm pretty sure most or almost all you guys heard of TODA's crazy vtec killer racing cams.

i was thinking since the b20 doesnt have any vtec.
im wondering if toda would work really good with the b20?

what are the flaws to these ideas?

Toda vtec killer cams are made for high revving vtec motors...ala b16/b18c. No way in hell even with extensive modifications to the valve train and block will those cams ever work in a b20a.



Think tank* a motor that revs only to 6500RPM and cams that help make power above 7000-9000rpm...think tank*

Cams can only do so much on their own.
It is possible to go too big, even if those did fit.

it would be to see the gains if they made a set for the h22

how do they those cams work?
does it really disable vtec?
cause im leaning towards the h23 swap.

make sure you do the demonstration to fully understand on how "camshafts" work and what they do. With the new knowledge, now you can understand how "radical" those lobes are on TODA Vtec killer cams & how they are useless in a b20a.

i know it controls on intake and exaust on how big the lobes are.

but what makes theses "Toda" cams so special?
and how does it enable the vtec all the time?


not trying to be stubborn you know.
just i really want to know how these cams work.

Here's some stuff i found on another forum by clicking the third link i saw when googling "vtec killer cams"...google is your friend

Design:
The overall design and construction of the camshaft has been very heavily revised from the standard configuration. Areas of stress, rigidity and weight all gaining significant benefit. Generally camshafts are manufactured from solid blanks. TODA Racing VTEC KILLER Camshafts are produced from hollow blanks. Being hollow not only reduces weight but also improves valve timing accuracy through a reduction in flexing as the overall rigidity of the camshaft is increased.
Unlike a Vtec camshaft, the Toda Racing Vtec killer camshafts have two cam lobes, which are of the same size. The Toda Racing Vtec killer camshaft is designed to bed in quickly and have a low wear rate.


Characteristics:
There is no longer a secondary (Vtec) lobe on the camshaft, the mid rocker arm is therefore redundant. It is removed and replaced with a rocker arm spacer. (PN. 14632-B16-000) The two pins in the remaining rocker arms are also removed. The oil feed rocker arm is fitted with a rocker arm plug to prevent any loss of oil. (PN 14651-B16-000) The benefits in a racing application for omitting the Vtec is the reduction of the valve train (reciprocating) mass and friction. The reduction in reciprocating mass and friction results in better engine response and increased valve train reliability. Furthermore, another benefit of disabling the VTEC system is the removal of fluctuations in the oil pressure system, securing reliable oil feed to all the main moving components. The factory “Lost motion devices” should be removed.

For best effect, Toda Racing Vtec killer camshafts should be used in conjunction with Toda Racing adjustable camshaft pulleys and Toda Racing’s 4valve throttle body Sports Injection Kit.
