I realize I haven’t described what Midlana looks like. While the details are still squishy, it’s basically a Lotus Super Seven with the passenger compartment pushed forward enough to allow a transverse drivetrain behind the driver. It’s not original (what is?) as there’s one manufacturer in England (Sylva) that produces one now, the Riot. Will Midlana be a knockoff of that, no, though all these cars are a knockoff of something. No, it’ll be its own thing, but will use commonly available composite so the builder has little or no messy, stinky composite work to do. It’s going to be “buildable”, easy to maintain, and inexpensive.

Thanks for all the comments regarding seat placement, sorry I couldn’t respond to everyone separately. I think I’m going to stick to the traditional side-by-side placement. It’s a combination of reasons: routing the seatbelts, not getting undue attention from safety inspectors, motor vehicle registration people, and later, cops, and, being able to hear, say, a driving instructor. From a selfish point of view, it’ll be much easier to get it through registration in California if it looks like a “normal” car. Then there’s the “too different” aspect; I’d like this car to be something people <i>want</i> to build, and the center seating might be a bit much. I know I’ll never make everyone happy, but alienating a huge group right off the bat’s probably not a good idea!

Engine choice: The builder will have a decent-sized bay to install whatever they want (with limits). Everyone has access to different engines due to differing budgets and regional availability. Then there’s form factor. There are many transverse FWD drivetrains out there, all with similar layout; that’s the type that Midlana will accept. Of course there are other engines like the Subaru flat-four: low, light, with a “real” transaxle. The problem is that the transmission tail shaft sticks out quite far past the axle centerline. That’s of no consequence if the car’s designed for it, but it’s not. A transverse layout is shorter, front to back, which packages much nicer, and there’s the rub. There are far more transverse drivetrains out there than Subaru drivetrains, so I didn’t want to force builders to use only one engine brand. (Technically the engine bay could be made large enough to fit everything on earth, that it gets out of hand. This is the consequence of following a cookbook; you’re stuck with the designer’s vision).

I have a question for you: if you had a choice of building a car with two seats side-by-side, or two seats, one behind the other, which would you choose? In the first case, the car could be considered more “sociable”, in that you can easily talk to and see each other. This is important, but I’m not sure how much. I mean, how many people do you Really give rides to? Does your spouse Really love riding in the car, or is it more to be polite and put up with your crazy hobby.

Or, do you compromise the social aspect of it by putting yourself front and center, like driving a “real” race car. Also, the car wouldn’t have to be all that much longer since the rear passenger’s feet could straddle the front driver’s seat. There’s no pesky driveshaft tunnel to fool with, so that’s not an issue. Hmmm, something to think about, but I’d like comments either way. I think I know the answer, that it’s just a bit too “different”, but I’d like you to consider what you get (as a driving experience) before discarding the idea).

It suddenly hit me today that unlike Kimini, where I did anything I wanted and didn’t care what anyone said, now I have to care what people think. It’ll take some readjustment, having to listen to what people want! Or do I say, “This is how it is, take it or leave it.” That doesn’t do well to sell books with that kind of attitude.

Let me know. Of course, none of this is going to happen unless I find a drivetrain.

Just this morning I was very, very close to getting a great deal on pistons and rods for my chosen engine. Then, I started thinking about it all and canceled the deal, but let me back up and explain. I preface this with, once again I’m going mid-engine.

My brother, who’s using the GM supercharged 3.8l V6 in his Stalker, of course thinks that it’s the no-brainer obvious choice. I said there aren’t decent transaxles for it, and adapting one to it seemed silly, but he said with enough effort I could make it work. Exactly… I don’t want to reinvent the wheel when there are already FWD drivetrains waiting to be used, and not really heavy one’s either. I’m comfortable with Honda engines, having built Kimini using a Honda H22A1. Because of the awesome aftermarket support, both in parts and forums, I’ve decided to stick with them.

So over the last six months I’ve been thinking about which drivetrain I’d like use. While Midlana will accept many drivetrains, I still had to pick mine. Naturally I was drawn to the largest 4-cyl that Honda makes, the K24 (2.4l). There are four variations, going in the CRV, Acura TSX, Euro Accord, and USDM Accord. Each has different power levels, with the TSX being the highest, Unfortunately for that very reason, it’s the most desirable and sought after. On the other hand, the Accord, making about 20% less power, is typically about three times cheaper – really. Many people convert these over by adding a better head, changing the pistons, rods, and so on. It wasn’t until today that I started rethinking my whole engine selection. If I get the Accord engine, I’ll have to build the engine before I can use it; that wasn’t the intent at all, I want to drive the car as soon as it’s on its wheels. Then I started adding up the costs of getting a Accord engine to what I want and was surprised that, for the money, I could just go straight to a 200hp TSX engine. It’s a slam-dunk solution; buy it, put it in, and I’m all set. Even better is that when I go forced-induction, zero internal modifications are needed. [that’s what I thought at the time, hah (Sept 2016)]

Of course, don’t expect what I say today to be what I do tomorrow, as I’m full of vague nebulous ideas that come and go all the time. Just because I come up with something doesn’t mean it’s going to stick around, and it can be discarded like yesterday’s Hollywood starlet. On the other hand, I realize people like reading along, following my thought process, be it smart or completely idiotic. Anyway, the more time I spend typing the less I have to work on the design, so I’m off to work on that. I’ll discuss the plan in more detail in future entries.
