S2000 Minx
Posted by: Frizzle Fry
Date: November 20, 2008 12:21PM

Hello all,

New member here. I have a 1966 Sunbeam Minx with an ailing 1725. I've been searching for a suitable swap to modern EFI and have come to the conclusion that the S2000 F20C and 6-speed are the perfect match for this car (small, light, and powerful). I've seen the article on Joe Curry's 1963 Spitfire and was hoping to get in touch with him or someone else with experience with these engines. Specifically I'd like to know what ECU reprogramming was done and what software was used to do so. Same question on the wiring harness; what mods were required? Fuel pump used? Also, and this is a big one, I've read that Honda engines spin the opposite direction versus "conventional." Is this the case for the F20C and if so what rear was used? Perhaps a "conventional" rear could be flipped?

Obviously there are quite a few details to sort through, but I enjoy this kind of challenge. Any info would be greatly appreciated. Here are a couple pics of the car for your viewing pleasure:

Not familiar with the Minx so let's start w/some basics... like engine length, width, & height -- e.g., will it fit w/o a lot of cutting/welding etc.

Transmission tunnel -- width of the tunnel support the 6 speed you're looking at?

Rear end -- will it hold up to the torque of the S2000 (no idea what the torque is but something to consider)

Fuel pump... I'm guessing that car's tank doesn't have a return line so you'll need to plan for that... and depending on the fuel requirement of the S2000 motor, you may need a larger fuel supply line.

Just some thoughts to get the ball rolling.

Wow. Saucy Minx!

I don't know much about Honda engines - hopefully experts will chime in shortly - but I know a cool looking car when I see one. I bet there's room in that engine compartment for lots of different engines. More photos would be fun to see, if you've got time.

I take it that his engine bay is very similar in size and type to the Alpine? The front looks very similar.

Do you have any dimensions of the S2000 engine? Where does the shifter sit compared to the very front of the engine balancer/pulley? Are you going to run into shifter issues inside the car?

Itís not really a matter of will it fit. Take this V8 Husky for example (basically same as a Minx from the doors forward). [www.whatsahillman.com]

Itís a matter of how little can I cut. That will be answered as it goes in. Fabrication is not a problem. The engine/tranny are on the way so Iíll find out one way or anotherÖ

The rear end I figure I'll run the stocker until it either dies or I decide it needs to go. Then Iíll probably go with a Dana from an old mail Jeep or a Tiger rear. Iíll figure out what ratio I need based on how it feels with the stocker. IRS would be cool, but I want to keep it simple.

Fuel pump and lines are a good question. One I hope I can get answered by someone whoís done an S2000 swap.

Thanks for the response.

I donít know how similar it is to an alpine. The shifter location I have looked into and though I donít have the exact dimensions, I do believe with a little fabrication I can move the shifter forward on the tranny if needed. Hereís a pic of an S2000 engine/tranny:

This is a really cool project!

Some really well-taken photos too... this one is worth a couple thousand words.

Hey, did you see that since you posted here last we've added a "project journal" section? In my opinion, it has a couple big advantages over Photobucket - especially from a visitor's perspective. No thumbnails, and thus no mouse-clicks. (While the visitor is looking at one large image, other images are loading.) Also, you can intersperse captions and comments easily.

Thanks. I'm still looking for the best place to post a project thread. To be honest I prefer to have the ability for members to leave feedback. Many times there are good questions and/or suggestions.

Looks great Mike. I really like the way you incorporated the S2000 shock towers into the Sunbeam chassis, very nice workmanship.

Hmm,

I have the same plan, only mine is to stuff a 240SX motor (cheaper) into a MkIV Vogue. Front end is the standard 'Super' design though. The most fun seems to occur with that steering linkage and clearance of the exhaust. Hence pick a motor that has the same intake/exhaust orientation as the rootes.

I'll be watching this with interest!

Couple of questions: Why all the Sunbeam scripts on a Hillman Minx? Was it called a Sunbeam in the US or something? In the UK the Sunbeam version of this body style was the Rapier. Also are you sure about that old engine being a 1725? Looks in the picks more like a 1500 with an iron head. What happened to that old lump? Parts for them are getting hard to find now.

Excellent work, looks great!

Rootes stopped using the Hillman name in the US in the early 60s. They were afraid of the bad reputation the Easydrive transmission got in the Hillman Minx. So we have Sunbeam Minxes, Sunbeam Imps, Sunbeam Arrows (Hillman Hunter) and even a Sunbeam Funwagon (a Commer caravan)

The engine would be a 1725, but in base spec with just 1 carb and a cast iron head. My Arrow estate had a similar engine, but I've made quite a few mods, including an alloy head, Alpine cam, and a custom EFI system.

Hey guys. Well we're coming up on three years on this project ...still progressing! Not sure if I ever posted the link the my build thread. Here is is: [67-72chevytrucks.com] Over 41 pages of mayhem there. Not far now!

Brake lines, fuel lines, wiring, exhaust, bodywork and paint engine bay, trunk, dash, trans tunnel, Raptor-liner wheel wells/underside, powder coat suspension pieces, dynamat interior, and 1001 misc items... But I'm pressing on!

Just cheked out your build site, that's some fab fab (fabulous fabrication)! Personally, I'm not digging the wheel choice. With that sedate body and those blingy wheels, it's kind of like outfitting your grandma with a thong from Victoria Secret. Maybe some big steelies would help with the sleeper look and would pay for themselves after you suckered some tuner cars into a few street races. Just my opinion, your mileage may vary.

Cracked me up! Neville, that has to be the best comment I seen on this site in a long time. Should be an award of some kind for it.

Oh yeah, went through all 41 pages of the Minx build. Just don't seem to be enough superlatives to adequately describe the skills, ingenuity, and daring. Fearless!

My grandma looks amazing in a V.S. thong ;) The wheel choice was made in pure hotrodding tradition; use whatcha got! I had them left over from another project and they happened to fit the S2000 lug pattern. The front tires could use a little more side-wall IMO and that contributes to the blingification effect. I dig the wheels on this car though (hated them on the previous ride). Trust me, it takes more than a set of wheels for the ricers to tuck tail. If anything a touch of bling is a provocation.

However, I am planning to do a 2nd set in 16-17" steelies with the factory dog-dish caps.

Glad you guys enjoyed the build so far.
