That way you have the security of a strong bottom end and you have no probs when the mod bug hits again Link to comment Share on other sites More sharing options...

I rebuilt mine using the atomic pistons, rings and 698kw rods, head and main studs, h/duty tensioner, sprockets and chain. It soon adds up and with parts and machining still cost $7500ish from memory and that's assembling the engine myself, double checking all the clearances. Jack bros in brisbane did all the work and everything was balanced spot on. Although few have had issues with cranks/ main caps walking I also went the atomic mains girdle, if I had my time again I would go billet mains as I had to get it line bored anyway because the girdle pulled the mains out. Billet mains would also dave hours when checking and looks heaps neater. Also one other thing is if you go rods with the gudgeon pin feed, get atomic do drill the top big end shell or get the engine shop to call atomic and ask. Set me back a few days as I ordered the bearings myself and didnt send them to jack bros, atomic actually drill the breaking shell smaller than the hole in the conrod, to a slight restriction im guessing. Apparantly the bulk of the spool/cp kits sold are 20thou over and even the smallest atomic slugs require bore/hone. Make sure you ask the engine shop if they have a torque plate for the hone, if they dont use someone that does. I would also go a little tighter piston/bore clearance if I ever build another one, as its a touch noisey on startup and for 20-30 sections after. The atomic spec is compensating for heaps off boost/heat, so for most punters you could go tighter no dramas depending on boost/majority of inteded use Link to comment Share on other sites More sharing options...
