Which connecting rods to use in C900 build? - Saabnet.com Bulletin Board
Currently rebuilding my '85 t-16 engine with a mish-mash of parts. piston/rod assemblies will be balanced with my balance beam scale, then the crank, flywheel and front pulley will be taken in and balanced, hopefully providing me with the silky smooth engine I desire
Pistons: smaller dished from 87T engine
Head: ported B212 with port matched B212 manifold, custom cams
Crank: will determine which is best looking later and use it
I seem to have 2 different types of connecting rods however. Both came out of B202 turbo engines
85 rods: 6 point fastener, coarse threads, more slimmed down looking. weigh 775g. 6.8g between heaviest and lightest
87 rods: 12 point fasteners, fine threads, more 'meat' on certain areas. these weigh 850g. 7.5g between heaviest and lightest.
so...are the 85-86 rods bad to use in this engine, or should I use the presumably stronger - but heavier rods? keeping in mind that a reduction of 75g per assembly (with the 85 rods) reduces rotating assembly weight by 300g, which im told is significant.
Im not planning on exceeding 6800rpm, and with the ported head, custom cams and smallish turbo the power output wont be that huge, however id just like to find out if the 85-86 rods can handle it before I spend the time to balance them and install.
