If you decide to keep your stock cams and don't plan on reving too high... save your money and don't get the springs and retainers.
On my del sol Si redline is 7200 rpms, i usually rev it to 6800 b4 i shift gears, i don't usually shift past redline, there's no point IMO.
well I already got Skunk2 Racing Valves with +1.00 mm overbore
so I am going to take it to a local machine shop and get a port and polish, open up those valves a little. (any tips would help, thanks). I am planning to go TURBO & NOS, D-Block....definitely need to get forged pistons n rods, and maybe a block guard, oh yeah get the block resleeved also.
