F22c in Caterham?

[Zoxygen]

Hey,

 

 

 

I have a F22c motor and was thinking of starting a project car this summer. Basically skipping all the chit chat, I want to get the Caterham starters kit and I was wondering if I would fit the f22c in a caterham without having the buldge that the WCM ultralight has.

 

 

 

Thanks

I'm guessing that's the S2000 motor, right? This doesn't answer your question directly, but it might help... that engine is very tall:

 

>Comparison to Mazda Miata engine. Perhaps someone with a Caterham can make some measurements for you. Welcome aboard.

welcome aboard zoxygen,

 

 

 

I have a turbo Miata engine in my Caterham SV. Judging from the pictures and text in the link in the above post, you are going to have quite a hood bulge. My Miata engine barely fits under the nose cone and bonnet and I have 3.75" ground clearance under the sump with 16" wheels. I had to make minor mods to the intake manifold to clear the bonnet. Pictures of the fit are here:

Thats what I was worried about.

 

 

 

When I saw my friends f22 I noticed it was rather tall, but I wasnt sure if thats the may most are, guess not.

Are you trying to put it in the wider SV chassis or in the traditional width car?

 

 

 

I'm in the process of putting as S2000 engine and transmission in my Birkin. It's a very tight fit. To get it to fit in, I am reworking most of the chassis tubes in the engine bay as well as the transmission tunnel. The good news is that the chassis torsional stiffen is up by 45% with almost no weight gain according to my FEA analysis.

 

 

 

The mods that I'm making to the engine is to dry sump the motor, cut the oil pan down, and cut the valve cover down. Surprisingly , the valve train is about 1 1/2" below the top of the valve cover. It looks like this is all for venting the crankcase as well as the coils. I believe that with cutting down the sump and valve cover, it will fit without a bulge in the hood and the sump hanging about 2 1/2" below lower frame rail, but it is a very tight fit. It may prove that I need a bit of a buldge in the hood in the end though.

 

 

 

I looked at an SV chassis earlier and it will likely fit in the width in the engine bay, though not sure about the transmission fitting in the tunnel. I think the engine's height will still be an issue unless you want to take the same route that I am following, and even then, it still might not clear the hood.

 

 

 

It definitely won't just drop in as stock and clear your hood assuming the dimensions of a Birkin and Caterham are relatively the same.

If you can change the gearbox, it then becomes a lot easier.

This is the F20c fitted in a Westfield.

mhc,

 

Do you have a link or contact info for the person or company building the F20c powered Westfield?

Getting the gearbox to fit is definitely one of the bigger challenges. Using another gearbox like a T-9 would make it a lot easier, but then you have the mating of the tranny to the engine to deal with.
