1300 lbs wet should be doable (not to sure about your 200 pound ass)

Are you guestimating total finished weight? (with you in it?)

what kinda hp do these engines put out and whatdo they weigh?

if I can shed a hundred pounds or so and not loose too much power, i might consider this as a possible motor for my locost

100HP and according the site I posted above

DOHC with an automatic tranny flywheel and no manifolds: 133lbs

The 3 cylinder turbo motor is even lighter (you can pick it up by yourself) but only something like 75hp.

The engine is just about perfect really - only thing that bothers me slightly is the apparently lousy gear ratios in the Samurai box.

well that would kill it from my perspective, this will be a Hillclimb, Autox , sunday driver.

Samurais are pretty popular with the off road set so its entirely possible there could be different aftermarket ratios avaliable ... its about the lightest powertrain with decent power besides bikes. Older Alfa dohc motors and the Lotus 907 (~140hp - Jensen Healey, 70s Lotus Elite, Eclate) would be pretty light too but are of course rather old/high maintaince/etc.

The gear ratios don't seem too bad, 2nd is a little tall but with the right rear end it should be fine. And I think I found one in a Kia Sportage in my local U-pull it place.

The engine is 100hp stock with a 7500rpm rev limit, but what I have been reading about the engines potential is encouraging, there is a guy in Canada than makes a wide range of cams, and the engine can be revved to 9000rpm on the high quality stock valve springs. Add that to a little larger throttle body, and a well designed header and you are looking at a 130hp screamer.

As for weight I was talking with me in it, I'm not sure it's possible but I will try. I am using a lot of parts from a Metro donor, and trying to find a light rear axle. The Sportage might work.

Donor #1 has been aquired. And I found a Datsun 210 in the junkyard, will the rear axle from that do? It looks really small and light. Runs nice, really rusty, but it will supply my engine, pedals, brake master cylinder, chassis and engine wiring, radiator (tiny! no fit issues here) ummm...a few other parts, maybe wipers if I decide to add them.

I've heard the 210 axle is a little narrow - might be ok with spacers. What is the distance between inside of the drums (the MkII Escort for reference is 48" - I believe 50" is around ideal depending of course on the offset of your wheels).

That might work then, because the bolt pattern is 4x4.5 which is pretty useless. If I want 4x100 like the chevette spindles will be I will have to get wheel adapters, which are an inch thick minimum. Any other axles you suggest?

4x100 live axles don't seem to be all that common. There's the Chevette, which isn't all that usable because of the big torque tube stuck on the front of it. Another possibility is the AE95 chassis Corolla AWD (these were badged SR5 in Australia - may have been the Carib or All-Trac in NA) from about 1988-92. These use basically FWD Corolla running gear (which is 4x100) and have what looks like a fairly light rear axle. The only drawback may be the width - I found the rear track listed as 1380mm (about 54.5") but that would be with FWD offset wheels which effectively reduce the track relative to the axle width. Might be worth crawling under one in a wrecking yard if you can find one.

Here's a picture of one borrowed from Wikipedia http://en.wikipedia.org/wiki/Toyota_Corolla#Sixth_generation_-_E90_series_-_May_1987:

Hope this is helpful,

Not a Suzi build, but.... I'm using a 4x114.3 Corolla GT-S axle, and Chevette spindles with Datsun 210 (4x114.3) hubs and rotors.

An option, if nothing else.

Actually, there is one of those at the yard, but I passed on it because I assumed the rear axle was not designed for 2wd, only 4wd. Should I go back and look at it?

eMKay · Post by **eMKay** » August 9, 2006, 11:15 am

It turns out that it's the exact same axle that's used in the Corolla, so I went and got it

eMKay · Post by **eMKay** » August 10, 2006, 8:15 pm

Got the shocks in, this is the largest single expense of the build. Since everyone seems to argue about spring rates, I decided on 175 rear, and 250 front. If they don't work, I'll try something else.

Other parts from donor #1

Wiring harness, notice the thinner left side, that part is already thinned out

Corolla axle

Repainted pedal box, these are really nice, there is a 90 degree angle from the firewall mounting to the crossmember mounting so mounting them in a Locost will be super easy...

Tomorrow I start the frame and continue de-rusting the parts. The fan surround is in the electrolyte solution drawing a comfortable 4 ams right now

If you don't mind me asking, where did you get your coilovers and what did you give for them? I love the look of them, are they adjustable at all?

eMKay · Post by **eMKay** » August 10, 2006, 10:26 pm

They are from Summit Racing, $133.88 each (part # HAL-ALN4855P), they aren't adjustable but they make them adjustable for $169.95 each. The springs are $34.88 each. I could have ordered the GAZ shocks but I hear these are pretty good too.
