Any TR7/8 owners here....

V8 or 4 cylinder?
Here is mine. This is my 2nd one. First one I bought in 1999. This one I got in 2001 and converted it to a V8 later that year. It was my daily driver for many years.
It did have a 3.5 with a cam and Offy with 500cfm Edlebrock, made 230hp (flywheel est) and 219ft lb on the rollers. Went pretty well. Clocked it at 144mph, which is plenty in a TR7! Also running 2.8 Capri front brakes.
Sadly the oil pump expired and knackered the engine. Currently running a late 3.9 with a serpentine belt. Stock cam, but same bolt on mods. I estimate maybe 200hp, Although in reality it feels just as quick, certainly has more low end grunt.
Also running a 3.9 diff at the moment, my 3.08 also expired. I do have a 3.45 waiting to go in, which I think will be the best of both worlds. The 3.9:1 diff makes for a brilliant rally style B road basher, but lacks top speed and cruising ability.
Rear suspension is pretty sorted with poly bushes and good springs/shocks. Front needs redoing as it's still on the old Shore70 bushes and some knackered shocks/springs (Spax or similar). Really want to fit roller bearing top mounts and uprated ARB's too.
Biggest issue is the body work has degenerated over the past few years. Really needs a new bonnet, boot lid, door skins and outer sills. It's still solid structurally though.
Being a FHC with no sunroof I think it's fairly rare these days.

The 1uz is an awesome engine. 300bhp no probs for £375 (the whole Lexus!)
Yeah I did buy an engine for another project. Stock they are 260-280 depending on exact model. Not many bolt on mods available cheap though. Although they take boost well. But a lot of work if already Rover powered. However if on the slant 4 and wanting V8 power they certainly are an option and in the UK a lot cheaper than a Chevy LS.
What gearbox are you running?
Interesting about the BMW gearboxes, I'd not come across this before. Do you have any links?
I did buy a Lexus engine (separate project). I did find someone who had made an adapter to a Rover 5 speed manual. But the box isn't really up to it. But the cost of a Toyota box was too prohibitive for the project.
BTW - what auto box when you say standard? Standard Lexus or Standard Rover/BL?

Something odd going on with the quoting so I'm not bothering!
On my 1uz conversion I'm using the standard lexus auto box so it's pretty much a complete transplant of the running gear & ecu.
I'd found a couple of links to the BMW mounting plates for a range of 5/6 speed boxes so that's definitely a possibility further down the line
This kind of thing seems readily available now which wasn't a few years ago when I started the build.

Good luck with the build, will be interesting to see what you make of it once running. Not sure I could do an auto in a TR7 myself though.On my 1uz conversion I'm using the standard lexus auto box so it's pretty much a complete transplant of the running gear & ecu.

How have you mounted the engine? I assume you've adapted the stock TR7 subframe to locate the mounts in the correct place?
