bigger is not always better...yet the skunk2 IM can fit a 70mm TB, porting has to be done to get a 70mm opening.

IMO, the work done to the IM is negligible.

thanks, making a 2.0 out of the b16a2, need more airflow.
HOW? Are you stroking and boring?

If so you better have so nice ass sleeves to with stand the sideload

i know this;) i planned on using darton.:) plan to bore 84.5mm and stroke it to 87mm, so what if it has a 1.54 rod ratio, so does type r and a gsr and they last. and i thought about the b18c1 block and b16a2 head. decisions decisions.

If you stroke a B16 to 87mm, your rod ratio will not be 1.54!!!!
TypeR and gsr have 1.54 but the 1.8 block is taller!
Dont use the B16 block, use the 1.8;)

blueSI sounds like you need to do some more research

Actually they don’t last “well they do but not as long as the B16A”

Yep that’s what the page says alright.

The Toda stroker kit uses all Toda products except the crank and that is from the B18C, as we all know the B18C crank has a longer stroke then the B16A crank so by dropping in a B18C crank into a B16 you will need to go with a shorter rod. The shorter rod length is where the side wall loading comes into play

Short rods = high sideload
Long rods = low sideload

I’m not saying you cant do it all I am saying is that I don’t think its worth it as it will shorten the life of the engine, also of note the shorter rods will NOT make as must torque as a longer rod setup.
