Come on Russ, with the right selection of goodies, most engines are able to get close to 100 HP/liter normally aspirated (Chuck's Law :) ). So to get 100HP for 1.3 litters shouldnt be that tough. It's only money. :cheers:


Speaking of which, what's the "Law" for $$$/HP in that case. I've got 3.8 liters and would be happy to get 300 HP without spending twice the amount on the engine that I spent on the remainder of the car. I'm not sure that can be done without turbocharging, though. I'd love to be proven wrong.

Cheers,

I have a 100hp Suzuki Swift GTi motor and 5spd tranny sitting in the garage for the last 4 years waiting for the old xflow to die but the xflow keeps on ticking. One of these days!!!!!!!!!!! Russ

Swift GTI is a great engine. 100hp was conservative. A friends dynoed 93 or 94 stock at the wheels That's more like 110 crank. Really light and durable.

Light is an understatement. The Samurai tranny I will use you can carry around like a loaf or bread. I bet the Suzuki motor and tranny combined weigh less than my Ford tranny alone!!!!

Thanks for letting me stop by and chat for a while, Nick! It was interesting to see how some of the MG stuff works in person--I haven't really studied up on that breed much. I'm still impressed with your wooden test frame you made...and the "welds" on it.

As mentioned, here's the places I got my shocks and springs from:

And the wheels:

Well this only took way too long. Determined to use as many pieces from the M.G. donor as possible, I crammed the original pedal box and steering column into the same space on the engine bay shelf by building a ridiculously complex assembly of boxes, brackets, and sheet metal that all bolts together in under four hours.

Image

I built a seperate gas pedal box and used that as part of the support for the brake and clutch pedal box. I could've welded everything together, but then the steering wheel would've been trapped, so the only thing welded in place is the mount for the steering column. The good news is, the steering wheel is just about exactly centered and the pedals mostly all move back and forth without hitting anything.

I assembled everything for these photographs, then took it all apart again so the pieces can all be stored in a corner of the garage until the day comes that I need to steer the car.

Ditto. Will you be adding a thin gauge sheet box over the whole thing and the column end to stop airflow into the footwell?

The stock pedal box cover fits over the pedal box, along with a felt gasket for sealing. The steering mount box will be welded to the firewall so that end will be sealed. The only thing I still need to do is fashion some kind of cover for the steering column. I'm hoping I can do something with aluminum sheet.

very tidy,

good to use as much of the donor as possible, do you have a choice of holes to allow for pedal box adjustment?

Other than the holes in the donor pedal box being slotted, there's no adjustment. Like everything else you do for the first time, I'd make a bunch of changes if I ever did this again, starting with moving the P tube an inch or so aft. That would widen the engine bay shelf, lower the steering column, improve access to the mounts, and allow for pedal adjustments. Right now space is at such a premium that every component is just about where it has to be. The pedals have just enough range of movement, the steering is centered, and I'll be able to close the hood. It's not optimal, but it'll work.

beautifuly done! How's the pedal height? I kept my pedals right on the deck because I felt the pedals were too high when I had the MGB box raised up. I like the way you did the steering column. I notice that your MGB steering wheel has the same rusty patina as mine!

Hi JD. I measured the height of the pedal box in the MGB at 15", and the locost shelf was only 13", so I added an inch and a half, which also lets me fit the steering column underneath. I've sat in the car with the pedals installed and they seem fine to me, but I have really big feet.

That steering wheel has to go, unless I can figure out a way to get my knees to bend backwards. Something in the 12-13" range would work, I think.
