Its a CF2 166 3L engine into a 156 V6 CF3.. It has been in and running/driving for quite some time I think, with a recent belt change too and to be fair to both parties it does need work and a lot of it is homemade/bodged rather than workshop standard but it is still usable. However the price was cheap and I guess the condition reflects this - I sold my 3 litre 156 for not far off twice as much and that was close to needing cambelt/clutch. The conversion was spot on though.
It doesn't badly need front ARB bushes but it will want them soon, it needed a radiator desperately which we changed, and then it needs the immediate electrical issues being sorted (lambda plugs chopped out, bad earths , some cut & shuts on engine bay sensors/loom, fan speed control wiring, flickering HID ballasts & whatever is causing the current gremlins etc), this is what it needs short term to be useable, it is still MOT'd & taxed. The big issues which are more long-term are it needs some welding to the rear floors, the plate behind the timing belt is still a 166 one so there is no top engine steady fitted, we could make a custom one to save changing the cambelt again but would prefer to do it properly, the breather system wants sorting properly by using a 156 V6 CF3 plenum & camcovers & pipes, the air filter assembly needs securing as it is just hanging in there, the manifold cat flanges are properly hacked and could do with being properly welded up/re-drilled & tapped as the downpipes cannot really be properly secured, and the rear lambda sensor wiring needs reconnecting.
It isn't great but even by the time you fix all this, it will probably still owe you less than buying a standard 156 V6, sorting out any inherent issues it may have and then 3 litre converting it.
