CamB 48 Report post Posted February 2, 2015 You probably don't need rods, in particular if you can find some 2002 or e21 ones (which are even stronger). Assuming you are looking to turbo a 318i, I reckon you have 2 options: 1) Turbo it, see what happens (might be ok, if you are sensible on boost). 2) Specifically build an engine for boost, and assuming you're getting pistons made: 2 litre crank (forged, counterweighted, longer stroke) http://www.trademe.co.nz/motors/car-parts-accessories/bmw/engines/auction-840438431.htm Then you can use the E21 rods, get them reconditioned / prepped. I'd say the combo of the above is cheaper than forged rods and gets you a forged crank and 13% more displacement. Then pistons to match whatever height the block measures to (and your combustion volume). I bought JE pistons to my custom specification a while ago through Glendene Engine Reconditioners (who did the other engine prep). My recollection is that they were only about 20% more than buying them from overseas. What cam (and rockers) are you thinking? Quote Share this post Link to post Share on other sites
