I've disassembled another TR4 engine and have another set of rusted 87 MM
liners and AE #13958 pistons to show for it. So it's either buy 4 new liners
for these pistons and machine them to fit, or buy a new piston and liner set.
The only 87MM oversize pistons I can find are 89 MM from BFE, and they don't
list them separately. Can I overbore the 87MM liners to 89mm and buy just a
set of pistons and rings? Or do I have to use their new liners? Anyone done
this or have other suggestions?
TIA
