WCM Ultralite S2k - things to look out for?


Recommended Posts

Evening! 
 

I’ve been looking for a 7 of some sort for a few months, to go alongside my 05 Honda S2000 I’ve owned for 11 years. The Caterham 420R is sort of my ideal performance. At 6’2 & 200lb I have been looking for an S3 with lowered floors or something similar more accommodating my frame. I’ve not yet gotten to sit in a 7 and am not in a point in life where building a kit makes sense.
 

I’ve considered the WCM ultralite as I’m fairly well versed on the motor/transmission combo and followed Rahul Nair through his blog while he owned a similar yellow WCM. I stumbled across this car a couple hours from where I live and had a good initial conversation with the owner who bought it as part of an estate sale. The car is a bit of a head scratcher, with a poor idle that shouldn’t be too hard to sort. It’s missing a muffler and the NOS bottle is a big red flag (which I’d remove immediately). The title states rebuilt which is how the owner claims the local dmv insisted a kit car be registered. The price seems fair as the rest of the car seems to be in good shape.

I’ve requested to be able to run a compression test as they’re a good baseline for f20c engine health. The car is drivable, but I’d be traileringit home. Anyone have a good what to look for list, either for 7s in general or specific for the WCM?

 

Thanks,

Reid

Do not jump in with both feet so quickly, find someone who knows what they are looking at, be it this car, or any others you may run across. You could either be getting a great deal (not likely o0n the web these days), or a real money pit. I tell people all the time, stop, look, listen. You came here looking for guidance, this is your first of what may turn out to be many.

For sure! Sorry that I may have made it seem like I was leaping. I fully intend to do my due diligence and was initiating this post as part of that. I have been watching the recent BAT auctions including a recent WCM and gathered there was a good amount of information that was perhaps gathered on this site. 
 

That said I grew up a fan of Caterhams and Westfields, became a mechanical engineer, got the S2000, took driving schools and track days, and have been reading and learning about these cars for years. Appreciate any and all feedback, thanks!

The ad has the usual classic red flags that make one pause - as you did by posting here first.  

 

@rnr @powderbrake Jerry/Rahul - as experienced WCM Ultralite ex-owners, any input on what things to look for when buying one?

Main thing for me would be the engine as new blocks are NLA and junkyard ones are pretty pricey. I'd also verify that the tuning system is something you can actually use/understand.

Mechanically the WCM is pretty simple to work on and at that price I wouldnt worry about things like the brake bias and diff bracing as they are easy enough to add on later. When looking at the car I would make sure that the footbox is large enough for you to use as it becomes smaller as the pedals go deeper in and can be a problem for folks with large feet. I wear size 14s and could only drive with driving shoes.

 

I had mine for several years (as you found on my blog) and had a great time.  The Ultralite has the right level of power for me and is very accommodating of taller/larger drivers. All the best with your search.

Thank you for the feedback, it’s greatly appreciated. No doubt, this isn’t a well sorted example like you made yours, and the ever-tightening inventory of these motors bears repeating (I supposed it’d be a relatively easier to swap a k24 Honda motor should it fail).


The Ga kit title process is nutty as well, they go through the rebuilt/salvage dept. This one is written as a 2008 Ultrasport 4dr “*Kit” model with exempt mileage as part of the being identified as rebuilt. 

 

I’m also weary of the current state missing a muffler, idle issue, and big nos bottle, but not afraid of a project and figure it’s worth a couple hour drive to check out.

 

thanks,

Reid

Good Morning,

 

Went and saw the WCM over the weekend. The engine had good compression, but was throwing a lot of codes related to misfire and the lack of O2 sensors. Additionally the motor was flooding 2 cylinders and we couldn't get the car to turnover (the owner had videos of it running/driving last month). Bummer. 

 

The body was in great shape, but overall the car was in fair shape, clean but needed tlc (new CV and steering rack boots), some light corrosion on the headlight chrome, and suspension could benefit from a refresh. 

 

Overall I'm not overly concerned with the misfire, I've been running & trouble-shooting Honda motors most my life (getting the injectors serviced and new coils would be job one). I fit well in the car, but without running it there are many questions (transmission, diff, suspension, brakes, steering, electrical) that remain unanswered.

 

Pros: The marketplace here in the SE is few and far between for Se7ens, reasonable price, familiarity with Honda motor/transmission, fit in the car, body in good shape. 

Cons: Unknowns, motor/ecu could require quite a bit of work, could use new header/exhaust, could use quite a bit of refreshing.

 

Summary, not nice enough to pull the trigger, not bad enough to write-off completely...

I like the WCM Ultralite, Roman was at a couple of the NJMP events. It's just about the only 7 that will take the Honda engines. I am having real problems with a K24 in my Locost because of the height on the engines. I think they look good and have good proportions.  It sounds like you have the necessary skills, so it sounds like a lowball offer might be the ticket.

i love my ultralite, even though its cost me a butttttload to fix a previous owners mistakes. we have a manual for the car now that lists a lot of detailed info. if you have any specific questions id be happy to answer them, if i can, but Loren, the current owner of the company is still around and is very generous with details.

I own a Westfield Mega S2000 that runs the Honda S2000 engine and trans and I have a friend that has a WCM. One thing that I think could cause as issue with the WCM is that there is no provision for fitting a sway bar front or rear. This can make it harder to fine tune the balance of the car at the limit - so if you are tracking or autocrossing the car it could be a real frustration. You can get pretty far into chassis tuning with springs and shocks but that last bit of balance can be very hard to find without the ability to adjust a bar.

 

Have you considered a Westfield? I'm 6'4" and 185 lbs and I fit very well in the Westfield even with a narrow Tillet seat. My guess is that at 200 lbs you might favor the stock seats as they are wider and you should slip right into place.

 

It could be an alternative if you've not considered it.

@RGTorque Good to hear from you Roman.  Hope all is well and it is great to hear that you have your se7en back together again!

 

Hi Mike, definitely feels good to be back into the swing of things.

 

regarding chassis tuning there have been guys who put sway bars on ultralites. though most who have competed with them have not found a need.
