A great engine choice if you
1. can find a runner at a decent price or
2. are enthusiastic about this type of engine and are prepared to spend out on a rebuild.
A mate of mine had one of these in his Esprit and it cost him a fortune to rebuild. He'd assumed it was mostly plain Vauxhall Slant Fan technology just with a Lotus twin cam head until he found the pistons, con rods and crank were all specialist Lotus parts. Getting hold of oversized forged pistons that would fit onto the existing con rods was particularly expensive.
The standard Vauxhall Slant Fan was not a bad engine especially in 2.3 litre form. Bomb proof bottom end because the thing was derived from a General Motors V8 just with one bank of cylinders removed- hence the slant.
