S2000 engine info

[Jackv4]

See a few of you are fitting the S2000 engines. What's gearboxs are used? As for the sump is it just the oe sump or is there a lowered one? To fit this motor into an SEIW has the tunnel got to be altered/ widened? Interested to know what's involved.

Most will use the standard Honda box that comes with the engine but I believe you can get a bellhousing to suit style 9 pattern?

 

I know of two cars that were older chassis (pre mega s2000 sport250) and it was a tight squeeze requiring some mods. @phil.mercboy for one.

The S2000 into standard Westfield chassis, had for many years, the reputation of one of the hardest engine conversions you could do. Every single part of it fought against you. Thankfully, that changed a little, when a few Honda to Type 9 gearbox bellhousings became available and that bit easier again, when Westfield launched the Mega S2000, however, the Mega S2000 did come with a redesigned chassis, specifically for the F20C engine and six speed gearbox.

 

The Mega S2000's mainly use the standard sump, with a small surge plate/baffle fitted. A small number have gone dry sump.

Both the Mega S2000 and the Sport 250, which uses a variation of the same chassis, are the widest tunneled chassis of any production Westfield chassis, I believe its a modified version of the old T5 gearbox tunnel, but widened slightly at the front, and modified at the top to allow the very tall S2000 bell housing to fit.

 

The chassis also contains more stiffening at the front along with improved front suspension geometry and significantly improved steering rack location, along with the highly reinforced Aerorace style rear chassis section.

Thank a lot for the info, There a lot of differences there,

Ive been on the verge of splashing out on throttle bodies for my setup but was summing up whether this would be a better way to go but im thinking not now, I don't want to go butchering my mint chassis tbh, The ITB's should get me around 200hp which isn't to bad tbf and will no doubt be an improvement in the way it drives, Probably stick with what I have,

Thanks a lot for the info, Both above replies are appreciated

Even though certain bits to fit an F20C to a Westfield are off the shelf parts, it’s still an expensive operation compared to most, more common engine conversions. (And that’s not counting the astronomical price rises F20C engines plus gear boxes have gone through in the last few years as the original S2000 has gained modern classic status).

 

The problem now, is that a converted SEiW is going to cost a lot to do well, and significantly, unless it’s either a really, really special conversion, or one done by a builder with an extreme pedigree for turning out class winning competition cars, is just not going to be worth a fraction of what it would cost to make.

 

The Mega S2000 as an off the shelf kit, has effectively taken big chunks out of the second hand value of converted SEiW’s that don’t have the pedigree or something truly unique to rescue them.

The only downside I can seem to see with the F20c engines are the high prices they're now commanding, usually north of 3K.  The S2000 stopped being produced in 2009 which means decent engines are becoming harder and harder to source and there aren't many low mileage examples out there. The other alternative is a Spoon Sports-built F20c crate engine, but they start at £9.5k at the moment
