The biggest complaint I hear about the S2000, is lack of low end torque. I want to know if anyone makes a stroker kit for this car. if displacement was pushed out to 2.2L or 2.4L I think that the low end torque would be much better and it should increase hp.

 

Search. I believe Feels is the only mfr. and it comes at a high price tag. You would be better off getting a custom crank and rods made.

A stroker kit would come at the cost of slower revs and a lower rev limit. Not doing so would likely kill the motor pretty quick, unless you went with all forged pieces. Maybe even if you do.

 

I was thinking that Spoon (maybe Toda?) had a stroker kit. At least I think that I've seen it advertised. 'Course, it may be vaporware, as has been the case w/ their cams. I understand, tho, that they may actually produce and sell cams later this year.

There was a rumour (or something more according to the King Motorsports website) of a Mugen 2.2 litre stroker kit. Don't know what happened to that.

The feels has a 2.3, not 2.2. pretty expensive though.

Inlinefours even has a price tag for the spoon cams, what's the story?

 

You could build a stroker using the Feel's kit, but let me suggest an alternative.... You could build a completely NEW bottom end using a NEW block. You could use Cunningham rods and Arias pistons or Weisco. You could build this setup and run 12.5:1 compression and have a motor that will support 10K operation all day if you upgrade valve springs. If you went Arias, you could re-sleeve the new block and run larger pistons, and still keep that high revving character of the F20C. You could do all this and have a completely NEW bottom-end for $5000 and still have your stock motor, so you wouldnt have to worry about blowing up your stock motor.
Also, a higher compression setup would allow you to really see the gains of running cams.
You could spend $5000 on a stroker, but honestly if you did this, you would see a lot of gains, especially in torque. I will report my results on this at a later date as this is my christmas project.

If you're interested in getting the Feel's stroker kit we can import it for you at a very good price. We are interested in having someone in the US install it to report the results. It takes about a month to build the kit, and then whatever time to import (expect 2.5 months) which puts the stroker about 3 1/2 months to 4 out before delivery.

Longer stroke Honda engines with less efficient breathing have revved higher than the S2000 and held up. Quite a few B18Cs with TODA B or C cams rev to 9500 and can rev to 10,000, maybe 10.5 for really short bursts with an awesome bottom end. On Honda Tech the member sgt has a built B18C that he revs to 11,000 for really short bursts, and he has a video of it. you can search for it if you want. www.honda-tech.com www.sgt-racing.com

To make an S2000 2200cc, it would have to have a 94.68mm stroke with the 87mm bore. That's quite a bit longer than the B18C's 87.2mm stroke but a few built all-motor drag cars with deck spacers and Crower billet 95mm strokers rev to 9800-10,200 rpm.

Where does Feels get their crank or how do they make it? If I were going to make a serious all-motor stroker F20C, I would have it resleeved as well as stroked with a custom billet crank. Crower makes custom billet cranks for about $2200 and billet rods for $170 each. Then pistons, possibly with a tighter ring stack and moved up pin for a longer rod. I do not know the bore spacing of the F20C or how much the bore can be enlarged, but with a square 89mm bore and stroke you would have 2214cc, and not have too long a stroke to permit above 9000 below 10,000 revs.

You guys need to check this site out. They build complete new bottom ends for the s2000 as HAMS was speaking of for around 5k. This sounds friggin awesome. They also sell heads with the toda cams and better cam springs!
