How many people have used a TR7 as a donor? There a cheapish one that's rotten but apparently has a good engine near me.
My biggest concern is the track width, how do you go about adjusting the chassis plans to accommodate different track widths?
Is there anything else I should pay attention to in terms of chassis planning when looking for a donor? There doesn't seem to be a lot of rwd
donors around, miata and rwd mini truck prices are sky high, and few and far between.
probably none - cant think of a single kit that would use a TR7 ( or any car thats been out of production for 35+ years)
Tr7 engine was also a terrible engine so not even worth considering just using that, low power and prone to leaking like a sieve
Always best policy is to find a kit that you really want to build , own and drive - then start looking for donor componets it
has been enginered to take.
there aren't really the locost kits available at a reasonable price in North America, at $10k, you're competing with very well designed and
widely built Shelby Cobra replicas from FFR. So it's more finding an affordable donor for a locost that's been widely used, and building the
chassis. At least in my opinion.
A lot of the companies that built kits here are no longer around. Plus I'm leaning more to the DIY, more fun and learning.

@winddude
probably worth adding your location into the system and then we can appreciate the particular challenges that being in North America brings.
there are some amazing builds on here with starting components as diverse as a model car for plans to VW bug to 7esque conversion. Something for
everyone

TR7 engine was awful for many, many reasons. Surely MX5/Miata are readily available in the states, plenty of kits already available to take those bits too, or can be adapted to plans fairly easily
3 series BMW
C class Mercedes
Both front engine and RWD and relatively common vehicles, surely you can pick one up for not much money?
Both of those probably have plenty of donor potential in terms of mechanicals as well. Sterring columns, brakes, hand brakes, drivetrains etc.

Has anyone considered a 1 series bmw as a donor ? rear wheel drive and some decent engines i think.
For Ref. TR7 Axle 52" same as English or Atlas ford axle that is commonly used.
But unless its a TR7 V8 the engine side of things is a bit crap..
Wasnt the Tr7 V8 engine the same as the stag, if so that V8 was worse than the slanting 4 pot in a TR7
But i could be wrong
No, the TR7 V8 was the Rover V8

Tr7 engine was half the Stag v8, hence the slant, Absolutely awful thing, they overheated & blew head gaskets & the studs were steel through an alloy head & they did the different metals corrosion thing & welded themselves together so you couldn't remove the studs or the head to sort the gasket. They also ate timing chains IIRC. I can't actually recall anything about the TR7 engine other than I think it had reasonable output for it's age & capacity. They obviously saw the light when they put the V8 in & chose the Rover over the Stag lump!
that tr7 sprint could go a bit more bhp than the rs2000
I never knew it was the Rover v8 in a tr7, had i known that years ago, i would of bought one "cheap"
from the front the TR7 was a really cool looking car, from the back, god it was pig ugly, designed by Stevie wonder ?

TR7 I remember as a bit of an ugly mug of a car.
Wasn't the inline 4 engine a V8 lopped in half?
Those were the rumours back then, and the four pot slanted over at an angle, in a pseudo V8 config
But if they were made of half a V8, what did they do with the other half ??

Robin Hood used to do one of their stainless steel monocoque kits based on the Dolly, not that that's much of a recommendation!
Jeremy Phillips fitted a TR7 engine to one of his early Striker Clubmans, too (in fact, it was the car that featured in the early build manual).

There's a shed-load of MX5 on Copart as we speak.
https://www.copart.com/lotSearchResults/?free=true&query=mx-5
Happy bidding.
If you only want mechanicals... there's a couple of flood damaged on there that should be cheap!
Cheers,

A bit of motoring history.
William Lyons of Jaguar visited the Triumph factory and saw the prototype of the TR7. He took a while looking at it from the side and then, walking
around it, said "Oh dear, it's the same on the other side".
Apparently the crease in the side was put there to reduce the resonant drumming of the monocoque chassis at speed, not an original design feature.
The TR2 through TR6 were all brilliant cars, using the incredible two litre standard vanguard engine, used in cars, tractors and armoured cars in WW2.
The 1949 Triumph Roadster used the same.
Working for AP in the early 1970's I was visiting the factory with the AP/Triumph Sales Accounts Manager to discuss brake and clutch developments
when everyone walked out because Lord Stokes had just cancelled the development of the Triumph Lynx (a car which combined the stag front appearance,
four seats and a dolomite appearance back end) "because it would compete against the Rover 2000".
In my view, Stokes contributed more to the demise of the British motor industry than anyone else. Wickipedia is far too kind to him, and I'm
trying to be nice.

Engines not necessarily leaky, mine never has. Similar power to the pinto of the same era, so very much of its time. Worst part is the head studs.... otherwise the engine drives much better than the paper figures suggest. (assuming you have never driven one)
But agree, there must be better, more modern options out there. Like the MX5/miata
So here’s a leap….I recall that the Triumph slant 4 was used by Saab for many years - just with a new head?
Use TR7 gearbox and back axle, drop in a Saab……..turbo………see where I’m going? Lol
thanks for the update.
