ok i decided to build an ls/vtec for my 90 civic si i was wonderin what a killer setup would be. should i use oem honda rods and like ctr or itr pistons or get after market rods and pistons? how much can i bore a b18a1 out to safely? i want to get into the low 13s with the setup so someone please help me out so i know how much i need to save up for this motor build. o yea my buddy works at a performance place so i can get machineing for cheap.
