Hi Guys,

Name's Ian from Singapore. Have a MY03 S2000 (prob Oz spec; 240 bhp, immobilizer).

Current mods include :-

- Jenvey ITB
- Motec M400
- Hks headers and Hi-power exhaust (yeah, have read that they dun make power but @ US$350.. used of course, i wouldn't say no and they do sound very good)
- Cusco super single clutch
- 4.57 final drive
- 16" SSR spec C rims
- Ohlins suspension

Recently dynoed @ 210 bhp on Dynojet. Would like more of course and now thinking of cams..

Unfortunately, i find that cams for our cars are extremely limited in choices.. Seems only Toda makes em.. Anyway, seems that the Spec A2 is a bolt on for the car and that the Spec B/C needs a change of pistons with bigger piston reliefs?

The specs on the website states that the lift for all the 3 specs are 13 and 12- 12.5 respectively for the intake and exhaust. if that is so, why is it that the A2 does not need a piston change? Is it because of the longer duration of the B/C?

If a piston change is required, then i guess i might as well stroke up to a 2.2L

Appreciate any advice.

Thanks guys.

BTW, how does one post pics? Cheers

 

You can either "link" them into your posts from a 3rd party photo storage site or buy a membership and store them here in the photo album that comes with it.

 

I wouldn't consider any of the cams to be "bolt-ons". Even the Spec As require you to remove the head in order to install upgraded valve-springs.

Even though the Spec B/Cs may have the same max lift, they apparently have more duration, or a "different" duration such that they would incur valve-to-piston contact with the stock pistons.

I'd love to see your current dyno charts if you have any.

 

Hi, thanks for replies.

My meaning of bolt-ons is no other changes neccessary other than valve-train parts (i.e. pistons mainly)

Have the hardcopy dyno sheets with me but still awaiting friend to email me softcopy. Anyway, still dunno how to post pics

Are there any free 3rd party storage hosts?

Thanks

*edit*
P.S. can visit the following link for a few pics. Including dyno too ... Cheers, Ian.

A company called CamMotion also makes camshafts for the S2k.


I use them in my car with EXCELLENT results.

 

you ahve those mods as well as ITB's and dynoed only 210? hm...kinda low aint it?

 

Yeah kinda low... but basically i guess its still *just* an intake and ECU mod... With ITBs, you prob can get away with running really wild cams and still maintain some sorta driveability, hence this post...

Pretty alright on the track tho... Them EVOs and WRXs have nothing on me on the straight (well only towards the very end )

Used to drive an STi, Faster perhaps but not as fun

 

Hi Green light,

Thanks for your info. Is yours a custom manufacture as i dun see an off the shelf item on their website. If yes, would you like to share your set-up with me? Would love to have other alternatives (Toda).

Cheers

 

CamMotion custom made the cams for me, but had ~10 sets of s2k cam cores made at the same time (to save $). CamMotion will make custom grinds to fit your application.

They do not have "off the shelf" cams in stock for the s2k.

Ask for Kip if you call or e-mail them.

He can make the non-Vtec lobes the same as stock and only modify the V-tec lobes, if that's what you want.

Would it be possible to cut bigger valve reliefs in the stock pistons to fit the Toda Spec B/C cams? Just another option that would be cheaper if you still want to run those cams. Or, like you mentioned, you could stroke it up to 2.2L. I think the F22C can easily run to 8500rpm...9k is possible also, but w/ a possible reliability hit.

Greenlight: how did your CamMotion cam specs compare to the Toda B/C?
