[LRCboi]

hey guyz

i have a few queston I'd like to ask related to the engine above

we are going to use it in speedway so 1/3 - 1/4 mile dirt oval we need to be 1300 and only allowed single cam camshaft 4 cylinder car engines but we are allowed to modify the engine no turbo no supercharger

we plan to use methanol

can somebody give me a heads up on where we should be heading with head, porting, cam, rockers anything really

also do any heads off biggger sohc engine fits this 1?

The B3 engine came in the Festiva, Aspire (here in the US/NA market) Kia (can't remember the model name) and the Mazda 121 in Japan and other select markets. There was a guy here in the US that built one up to 145hp, normally aspirated with side draft carbs, 11.5:1 comp., header, custom ground cam (I think), etc... I believe he was road racing the car. Biggest number changes will likely come from porting and higher compression. Just search the web on these engines.
