New guy with donor question
Hello!
I've been looking around on this forum for about a day and a half now. Last week when I was working on my car I realized I wanted to build
something completely from the ground up. I'd seen a Locost website before and I liked the principle of it. I've ordered the book, should
be here in a few weeks.
I'm sort of an early RX-7 fan and so I had originally thought to use one of those as a donor. We are severely lacking in very suitable donors
here in North America as everyone knows. Well I'd really prefer to avoid having to convert struts to uprights so my thoughts have turned
elsewhere.
I've been looking at small pick-up trucks as they seem to have the right sort of set-up. Has anyone used anything besides an S10?
Thanks,
Grant

Mercur xr4ti is the same as a 4wd Sierra - perfect donor, other than that AFAIK an rx-7 makes a good donor with useable front uprights and a great
engine for a Locost.

The engine, tranny and rear-end will probably be RX-7 no matter what. I know these engines and I love my RX-7, it's just oo heavy with poor
front suspension. I'd prefer to avoid having to convert struts to uprights, although the 86-91 RX-7 has struts that bolt togather and so would
work pretty well. I also want to avoid the uncommon 4x110 bolt pattern on most 1st gens.

converting sierra/mercur hubs to upright is very easy, if that makes any difference - its just a 20gbp 'strut adapter'.
Beware! Bourettes is binfectious.

Too bad the Merkur is a rather rare care overhere. We only got the XR4Ti which is somewhat hard to find. If I convert any strut I think it will be a
2nd generation RX-7 base model upright. I'm also looking at using an R6 rear shock with linkage or just at a lower angle for the shocks. Other
than that the chassis will look rather similar to a book chassis, the body however will be more in-line with a full-bodied car.

The Merkur xr4ti is 2WD.

Do you have these farty little japanese vans over there?
I'm planning on using uprights from a toyota townace.
 
a townace - for my uprights
(not this one though)
Most of them are twin wishbone, front steer. But most of them also have the steering knuckle way down low, so your rack has to go through the bottom
rail, which isn't ideal.
Pretty sure townace has the steering knuckle half way up, like the cortina.
Cheers

I just got The Book today so I'm gonna be reading for a while. Also going to be buying a house shortly so I'll have a place to start.
Looking more like I'm gonna use the toyota van front uprights and a corrolla SR-5 drivetrain, but later look at a GTS drivetrain once it's
been on the road for a little while. I already have one rotary car and I think I'd like to go piston with this one.
