As you may have already guessed from the teaser pics I am building a new bottom end for my car... I have been wanting to do this for a while... no particular reason (like one is needed after all this) but seeing as the head and its components is essentially new then I wanted a newly built bottom end and of course it 'might' involve a certain TFSI crank
Basic spec is 82mm 9.5:1 CP pistons, IE rifle drilled rods, ACL main and big end race bearings, TFSI crank, ARP main studs, ARP head bolts, balanced crank and rod/pistons, dual doweled crank pulley, new oil pump, new oil pickup, new crank seals, new oil pump chain, new oil chain tensioner, new water pump, manual cam belt tensioner, new crank pulley bolt...
I chose 82mm for a few reasons (rightly or wrongly), no need for a special or NA gasket to accommodate the extra bore, I wanted CP pistons as they appear to get good write up and Arnold at Pag Parts swears by them, I couldn't get a lower comp ratio piston without them being custom to accommodate the increase in compression the thinner gaskets would have provided and I didn't want 8.5: or more than 9.5:1 comp ratio, 82mm means a capacity of 1960cc vs 2008cc and figured I make decent enough power on my current 1781cc setup... hindsight being what it is maybe I should have gone 82.5mm or even 83mm but meh... its done and tbh I am not really bothered either way..
I was going to rebuild using my current block but as a good friend pointed out it will make an easier swap and I'll be able to sell on my current bottom end... considering most of that has done no more than 15k miles it made sense (so watch the classifieds
)
Parts are dribbling in but hopefully the block will be off for the rebore and a clean in the next week...
Will update as and when...
