Have a question of my own though, I currently also have a b18a and ctr pistons in my garage, would it be worth getting the ls rods strengthened and putting the ctr pistons in the block also? I keep hearing or reading horror stories from the crank and crank bearings not being able to handle the high rev of vtec due to lack of oil flow, what can I do to get the b18a block to handle the high rev of vtec, maybe type r oil pump, squirters, and water pump? If I do these type things, will the motor even still hold together? Looking for more torque. How high will I be able to rev on this setup? Would you recomend rods or would the ls rods hold up? Another ques., have s1 vtec tranny and exedy ls flywheel, do i need to get a ls cluth and pressure plate, or a b16 s1 cluth and flywheel? Yet one other ques., the oil squirters out of a type r, i know the block on the ls has no where for them, but i have heard of people using these in this setup, if so, what would have to be done?
