|Comments:||I've built many TR7 V8 conversions over the last 20 years using the usual
Rover 3.5 and Leyland p76 4.4L V8 engines. This is the most successful of them all.
The engine is smoother, quiet, and I expect it to be more reliable. It
starts easily, hot or cold, every single time and it has way more power
than any other TR-V8 I've driven. I'll use this car as a everyday driver.
Turn the key and go!
Toyota 1UZ-FE 32-valve quad-cam 4.0L V8 engine.
Toyota "1UZ" engines have aluminum engine blocks and heads, steel rods and cranks, hypereutectic pistons,
and six-bolt main bearing journals. The cylinder bore is 87.5mm (3.44") and the stroke is 82.5mm (3.25").
Rodney copied the TR8 subframe design, and added another bracket to support a Range Rover engine mount.
Key to the project: bellhousing and flywheel by Castlemaine Rod Shop (of Australia).

(Note: offered in certain markets from 1991 through 2000, the "Toyota Soarer"
model was similar to the North America market's "Lexus SC400" model.)
