so how much am i looking for a 1600 engine? remember its going to be a replica so not going into 10,000's lol
also what would be the best bottom end to put on it?
and would my current gearbox be ok fori t?????
I'd use the JC3 not your box its a bit stronger.
Personally I'd not bother with a 1.6 conversion stick a 172 engine in it least wth soem tunning you'll get 200hp which isn't that far off the 220hp of the S1600 race engines the 1.6 would costs a fortune to tune to over 150hp.
1.6 16V engine along with box etc say £1k its a load of work a 172 isn't much extra work plus you get the bigger brakes and wider track suspension so its seems worthwhile.
IF you wanted a S1600 type engine ballence the 1.6 bottom end and get throttle bodies and cams and head work thats going to set you back £6k ish though for 180hp or so IMO you could least use the 172 box which is stronger but why bother 172 engine is that much power before tunning.
