Hi all, as some of you know i am currently in the process of rebuilding a st215 motor. it was necessary to deck and bore the block .20 over and replace the stock st215 pistons with some JDM oversized caldina pistons (toyota brand) according to some guys on mr2oc.com the part number is: Piston kit (0.5mm oversized) : 13103-88580 which i saw referrenced to here: http://www.mr2.com/forums/turbo-engine-tal...er-request.html
Herein lies my dilema... Its been suggested to me to replace the rods due to the fact that the fourth gen rods are a weak point in that engine. the rods from the 3rd gen are known to be beefier. the question is will they: 1. Fit into the 4th gen 2. attatch to the piston ive found this VERY interesting conversation: http://s4.invisionfree.com/lexusaltezzaclub/ar/t11717.htm but it still dosent answer my question fully... Cuts the pilot is a BIG opponent of the 4th gen rods. (he says theyre made of cheese  ) however by good buddy camshaft cam (boosted185) says that teh 3rd gen rods wont fit. I havent been able to find anything...any help would be greatly appreciated! cheers!

SH!T...FCUK...DAMN.... UGH!
wow! Great info! thanks pit! i cant get any of the forged 185 or 205 pistons because the block has been bored/honed and due ot the fact that its now .20 over some slightly larger st215 pistons have been purchased from toyota.  seeing the size comparison has made me even more nervous... guess i will have to stick with the 215 rods and take it really easy! -------------------- QUOTE (Galcobar @ Oct 15, 2008 - 2:44 AM) You want power but have no money.
