Default Toda C's stock copression

I can get a set of them really cheap from my buddy. But stock copression with 2 layer head gasket. Think it will make ok power or need more copression.

replace it with toda b and you will notice that the car will respond better, and make more power on the dyno through out the rpm band.

toda recomend about 12.5:1 and higher comp. ratio for toda c.

yeah, i know that the Toda B's would work best with my setup
but i wasn't planning for any Toda Cams.....my build was setup for RM M22's but i was fed up with the wait and no local shops had any B's instock...only C so i picked them up cheaply new too

I tend to disagree here. I think the C's make as much power until vtec as spec B's, and MORE power in vtec. I haven't dyno'd my spec C setup on the same dyno, however. Look at the specs though - the b's and c's have the same non-vtec lobes, the spec c's have more lift on the vtec lobes.

Install, tune, make power.

yes but with lower comp. ratio the motor can't benefit from the Cs. we have dynoed a car before with 12:1 comp. and the Bs made more power. and thats tunning both cams, nit just slapping them on. the reason Bs made more power even on the small lobe was due to cam timming, were the Cs setting needed to make the power on top compermised the power on lthe buttom. were talking about 5-8 hp and maybe about 10 on the torque curve. (low cam)
as far as i can remember it was something like 201hp (Cs), 213 (Bs) peak power.
and the Bs reached peaked power at a lower rpm were the Cs reached the peaked at a much higer rpm

Default Re: (esponet)

is there a spec sheet on each that shows what the lift and duration of each cam is?

...esponet, you said that with a 12.1 the spec b's made more power, how high compression do you have to have with c's?

Default Re: Toda C's stock copression (esponet)

Hey, I think some great info is coming out of this thread.

I checked that link, and the only thing I could find about recommended c/r is this:

"For maximum performance, Spec C camshafts must be used with TODA high compression pistons and upgraded fuel injection system. "

So basically they recommend bigger injectors and higher c/r pistons... but they don't specifically recommend a certain c/r.....

I clicked on the link for "TODA high compression pistons" and depending on the motor, they range from 11.0-12.6:1..... So basically the only thing you can infer is that they recommend anywhere from 11.0:1 - 12.6:1... Stock usdm itr's are 10.6:1 which can get over 11:1 just by adding a thinner headgasket.....

I can say that I've run spec b's with stock c/r and no problems. I made power across the rpm band compared to stock cams with only vafc + cam gear tuning. I can also say that I'm confident I can get MORE power out of spec c's on that same motor using the same methods. How much more will be determined whenever I get the time to get them in and on the dyno.....

To the original poster: I say try them. It will be a good learning experience for you either way.

I wouldn't go the thinner headgasket route without first checking valve/piston clearance. Those C's have monster lift and duration.

The TODA pistons have much bigger valve reliefs cut into them over OEM.

Some good info on here - but why not just pick up the phone and call TODA Racing USA and see what they say about them? Go right to the source - they are great guys and customer service is

...or you could get valve reliefs cut into your oem pistons, but how mnuch would that cost you?

Not saying your wrong but I find it very hard to believe you can achieve 11:1 or even higher by just adding a thinner head gasket. Also I have known a couple of people using thinner head gaskets, and they all seem to fail alot sooner. This is the compromise you make when you use a thinner head gasket.

i was able to run toda Cs with stock jdm itr buttom, 1 (yes one) layer head gasket and the head miled over 30thousands. was able to adjust to 3degrees on the cams without any problem.
actually i remember talking to dennis from LDL, and he mentioned something like,
even with the same comp. ratio you could benefit from either Cs or Bs depending on what your car has, what type of racing you will be doing, and even how heavy the car weights. he then explained to me that a heavy car would be better off with a cam that has a lower peak power than a cam with a high hp but comes at a high rpm, cause with the weight of the car, the motor would be having a hard time pulling out of the lower rpm were as the cams with a lower peak, the motor will rech its peak and have the power to pull a heavier car. on a race car thats light, it really does not matter cause the car being light the motor will be able to pull up to the higer rpm band were the power is. (i don't know if this makes sense but its something to think about)

no doubt you can make more power than a stock itr cams, but to give you an example. my car ran better with toda Cs than sjunk 2 type 3 cams, even though i made more power with sjunk cams.
