Im confused. I'd go for toda, but a friend of mine said that they aren't the best choice, so I was wondering which camshafts to order Spoon or toda racing.

get the version 2 toda cams, but be sure NOT to run a thinner head gasket.

you might want to upgrade to toda valve springs too since the lift is very high on these cams.

 

Thnx,
but what can you tell me about those Spoon camshafts.

 

They never went into production, so far Toda's the only company making the cams, and there's lots more to come from Toda...

 

Thanks for info!!!

 

Spend the $ on the 4.7 Final Drive or the to be released 5.0

 

this is an idiotic response. sorry, but a bigger number doesn't always mean better. if you go with a 4.7 well.. it must be specific to a particular application and gearing that you are desiring, or else it's entirely useless to the average person. but what do I care, it's not my money.

 

Obviuosly you are not aware of shortened gearing true benefits.

IE the S2000 has a top speed in 6th gear of 171 MPH. By going from the stock 4.10 to a 4.7 you are effictively shortening the gears by 12%. Which means your top speed will be 153ish. While you probably will not ever see it.

What this also means is without changing any other parts and traction permiting your car will be aprx 12% faster through each gear. And still having the same smoothness through the powerband.

Now alot of people will say "yeah but my car is buzzy"

Well making a very high strung car make even more power between say 7-9Krpm will effectively do the same, but where gearing will make you pull hard through the entire powerband the mods will only give you a sweet spot

Now the question of drag racing. Well this calaculator say 4.xx is best. Yes but only with stock tires. Now I don't recommend drag racing your s2000 but I assume you can afford slicks. And since it's much easier to set FD with tire size simply do a bit of trial and error.

 

quite familiar with each of the gearing ratios and their outcomes - and I've driven a few combinations of each. all I can say is.. if you go with a 4.7, there better be a straight up purpose for doing so. otherwise, it is a waste and causes you to shift entirely too much if you are putting around town or on the backroads. the 4.44's are just fabulous. but anything more than a 4.7, that would be absurd. so no, I didn't miss the point - yet % gains don't factor in drivability outside of desktop racing specs.

I run around with an FD rx7 and we have stock 4.11 rear end. there was a write up sometime ago about changing to 4.33, 4.77. the results for acceleration assuming everything was the same wasnt very impressive to me. the stockers(4.11)(i know i am using drag racing terms here, i will be lashed for this later) will run the 1/4 in a 12.5 second at say 115 mph(these are all made up numbers. i will go fishing around for the real thread if you like). the 4.33 ran a 12.4 at 116 mph and the 4.77 at roughly the same. 0-60 was actually slower with the 4.77 because there was two shifts to get there instead of one. small things must be taken into consideration just like these.

You did your home work

 

i think a good example would be the jdm itr. the 97 model w/ the 4.4 final ran the exact same time as the 98 itr w/ the 4.785 final, because the itr actually had to make an extra shift

ummm...you do know the 97 JDM ITR used 15" wheels with that 4.4 (ala USDM ITRs) and the 98 JDM ITR had 16" wheels. The FD change to a 4.7 offset this increased diameter, hence maintaining the approx. same times.
