Interesting. I've never compared the 2 dimensionally. I just know they Haynes is 2" narrower than the 442. The seatback is also lower on the 442.

The Gibbs car is also referred to as a +221, 2" longer and wider, 1" taller, than the Ron Champion version.

Stock internals, for now at least. It's rated at 160 crank HP stock, but I'm planning on using Cosworth style intake, freer flowing exhaust, plus without power steering and A/C, I'm expecting to be around 180 crank HP. Not planning on turbo or supercharger, I want to keep it light and simple. My ultimate goal is about 200WHP, all motor, probably with a 2.5L Duratec. Stock ECU, with immobilizer delete, possibly a mild tune.

Ok, my arm was sufficiently twisted, and I started a build thread over in the appropriate section.

I've wanted to build a Lotus 7 type car for several decades now. I'm pushing 40, and no better time than now to start. I started with a McSorley 442E, Figuring that the bigger it is, the more likely that my "larger" friends could fit. After I built the basic frame, I started looking into the suspension design, which was giving me anxiety, since I wanted to use NA/NB Miata diff, axles, uprights, etc. I was told that the 442 was too wide to use stock axles. I didn't want to go down the rabbit hole of custom length axles, designing my own control arms, mounting points and geometry. I have a full time job, a 10 year old son, and a baby girl, I don't have time for all that. So, I cut it all up, and used the pieces to build a Haynes Roadster, using the Saturn Sports Car plans to adapt to MX5 running gear. This way, most of the work was done for me. Planning on using a Ford Duratec 2.3, NC Miata 5-speed, NB Miata rear diff, axles, uprights, brakes, steering column, and other small bits. Oh, and don't worry, the irony isn't lost on me, that the time spent cutting up one frame, and building another probably took longer than just sticking with the first frame. Anyway, I'm almost ready to start fabbing up some control arms.

I would love to, though, I am pretty terrible at documenting progress of any of my projects. I will try to keep at it.

Hey guys, just joined. Greetings from the PNW, West of Portland specifically. I am building a Haynes Roadster in my garage. I actually started with a pile of tubing, built a McSorley 442E, didn't like it, cut it up, then built a Haynes Roadster with those pieces. Planning on using a 2.3 Duratec, NC Miata 5-speed, NB Miata diff, steering rack, and knuckles/brakes on all 4 corners. So far, it's just the frame, but I hope to have a roller by spring.
