Just received this from Toda:

"The new design is more aggressive. The first design was very beefy in the midrange and the new design carries the same beefy midrange with better high end. The F20C is very optimized from the factory and tolerances are very high. The new design is at the limit of camshaft aggressiveness (13mm lift). Any more lift and duration would cause valve-to-piston contact and valve-to-valve contact. "

Sounds like my kind of camshaft! I'll be in line for a set and looking for a tuner in the MD/VA region to help me get all the parts talking to each other.

 

It would be very nice if the new Toda cam will be plug and play with all the Mugen mods. I too have the Mugen ecu and header and I look forward to seeing how this new cam will do with such mods. I hope King tests the new cam rather than the first one in the test they tell me is forthcoming.

It works fine, just trust me on this, no problem with air/fuel if that is what you guys are wondering.

 

The newer cam or the first Toda S2000 cam or both...? Thanks for your info!

 

the first run, I haven't seen the second ones made available yet. But the first runs definetly do not have any problems working with the Mugen ECU. I have email from Toda Japan saying that they have talked to Mugen Engineers about this. Toda and Mugen work very closely in Japan. But I also already run this combination in my car for about 6 months now with no hiccups at all.

I wonder how often the valves springs will need to be changed to keep engine reliability with this cam lift of 0.512", to take into consideration spring fatigue. I hope not at all, or at least not until several thousand miles have elapsed.

"Some cam grinds will have a larger amount of lift than the standard cam, and while no-one denies that more lift will give you more power, I don't believe that for road & club use you need a great deal of lift, ie, 0.350" lift is normally a pretty small figure for a performance engine, but with a multi-valve twin cam that is quite often plenty. You'll still get an increase of power with increasing lift, but at a rapidly decreasing rate, and at a rapidly INcreasing rate of unreliability. I've seen some Group A 2 litre touring car race cams with 0.550" lift - The valve springs have to be changed every 2 hours ...
For what it's worth, the cams in the 4AGE in my AE-86 road car have 0.290" lift and it makes 100hp per litre - Not bad."
