Hi guys I'm just looking into the what's the highest an s2000 is able to rev too, obviously I know there will be some serious work involved. But I find my self thinking that anything above 10k on bodies would be insane.

Cheers Dan

 

I wouldnt advise building an engine around a Rev limit.

You could do 10k on the standard engine, it just wouldnt last long.

Piston speeds kill it.

You are into heavily built race engine territory and that would cost £££££. You'd do it to win races rather than for noise. You can get more reliable power from displacememt increase, but then you have to sacrifice some rpm.

 

I know it wouldn't last long on standard internals, just wanted to know what the highest a f20c will rev to. And if any one has built one. I know if I want power then a charger is the best to go for but I like the throttle response of na.

 

The standard engine has a limit of 9250. This is pretty high. If I was going to do 10k, I'd be looking at titanium rods and balancing the engine along with losing a piston ring to reduce the friction. The crank is fine. If it were me, I'd look at sorting the head and leaving the bottom end alone. By all means raise the revlimit to 9400 in case of gearing issues, but set your power around 8750-9000 with 9200 your standard change point. 270 is doable with headwork, cams, ITBs and an ECU.

 

Mine had 270 whp without ITBs. You don't need them for peak power.

 

I think Matty's engine is built to rev to 11000, hence the reason it's capable of putting out 1200 hp.

 

I need to do some investigation on this, I currently have the spoon throttle body, js racing ecu mani and decat. Along with mugen ap2 exhaust and aem induction kit. Haven't dynod the car. Not sure what power it should run.

So you recon some head work would be better then, any one port and polished a head with some higher lift cams?

 

You only need the engine management tool to change you're maximum Rev limit...

If the engine doesn't matter to you then raise it to 12k and just trust yourself...

What you've listed above is minor engine work required to get a few more bhp and torque.

Are you sure you have the right contact for head work... The s2k head comes standard with a flow rate that most port and polishers will be very happy to achieve after they've finished...

if you want more revs and it last a few months... Be aware though pistons will come through the head, crank will come through the block, connecting rods will bend, valve train will disintegrate... So that's what you'll need to spend your money on... The whole lot...

Your talking a full engine out and rebuild with the best parts available... £25K might get you there in my opinion but others can be more specific on price....

MB races his and has experience with new race built units...

The best solution in my opinion for a very high revving car is to put a Honda bike engine in the boot.

 

I'm new to owning the s, before the s I owned a 400bhp focus with a GTx28 turbo and fully forged bottom end.

I am simply trying to find the safe limits of the engine and if it is possible to increase the Rev of the engine. I know honda have spent time on the inlet etc and many parts are the best they can be.

keep looking at itbs to keep the throttle response of the engine as I love how she drives now.

There is loads of info on the site. There is a search button at the bottom. It's very helpful,.I'd grab a coffee and your comfy chair and spend a few hours or days reading lol.

The s2000 was Honda 50th anniversary car, It was designed very very well, the engine is brilliant as standard... It was meticulously designed by Honda to be great, 240bhp from 2ltrs N/A isn't easy... They used forged internals, polished inlets, very high piston speed (9250rpm) stainess exhaust, chain driven, etc etc etc.

ITBs are great for sound and Throttle response, and some hp but not loads of Hp, most owners supercharge the car for both hp and throttle response improvements.

The safe limit for the f20C is circa 400-500bhp. Some have it higher... 600-800bhp on some turbo builds. OE internals.

The less popular safe sealing limit.is 350-400bhp. It's my view that over 400bhp is a.bit risky.

The diff is an area needing improvement... Puddymod do nice work on our diffs.

Some have had race f20c engines built and fail because the attention to detail just isn't there as it is for the OE unit.

TTS or TDI north are the guys for you to speak to.

There is so much to discuss with the f20c.. But boost is the best way to get more bhp... ITBs would be great too though. :-)
