speak to karl norris as hes done lots of research into 1.6 bottomends
i belive the standard crank is fine upto 330bhp i heard was said
or speak to dazc as hes done alot of work on his but unsure of the spec, i know its not set of mahles and arp rod bolts only
might be cheaper to buy shings car

, thats a animal and very well setup
again thats a karl norris machine
