Probably the same as a 1600 cvh as standard but with zero miles to the gallon due to big juicy carbs. 200 quid will get u a new engine compared to over a grand for what u plan.

Yeah i'd say about 85 BHP but it will be a very light car and will handle wickedly too. Plus its different so go for it!! I think if u get everything lightened and balanced, steel crank, and up the compression a wee bit plus laireyer cam for the carbs you'd be looking at 90bhp+, as it will rev more freely and bottom end will be able to hack it. Think 120bhp is the most u can push outta one, and thats a propper race spec jobbie i seen, tho it was a 1.3 crossflow engine as opposed to the HCS :rolleyes: :Q

You in theory can get similar power as it is the same engine with different stroke (hence the differing cc)

If you do everything you plan expect to see about 90-100bhp

Steel crank is absolutely not needed for what you want as it costs £1000 and only needed on mega power engines or ones that rev to crazy revs. the rods and big ends will go before the crank does, so if you want anything steel get steel rods and ARP bolts...other than that do it, be nice to be different! :D

WHY did i recomend a steel crank? :rolleyes: Yeah just uprate the bearings if u going for a free revving engine and what dave said. I'm really stumped as to why i put that now, as i'd rather not answer q's than give wrong answers. :-? how bizzarre, think i had NOS on the brain!! :devil:
