Ok yesterday i went to get my car tuned, the car has a greddy kit with a 3inch dp, and the block is built with cp 9-1, eagle rods, and bored to 81.5mm.
I used the stock crank but it needed to be cut and oversized bearings were used. We took the car out for a street tune first getting on it now and then then i got on it fully in 3rd to 5th and i spun a rod bearing.
So i pulled it all apart today the crank is fucked the rods look like new, but i wanted to know what u guys think i should do i was going to by a new b16 crank and acl rod bearings and main cap bearings and put it all back together. is there anything else you guys think i should do any imput would help thanx guys
the motor had 300 miles on it when this happened
