ok, so im just doing some preliminary build ideas for my engine. im not doing anything anytime soon as i have no money or time, but im just brainstorming (dreaming in other words, lol)
my question is about the weight of pistons. i had initially planed to use JDM ITR pistons in my gsr block. they are a direct fit for gsr rods. i was also going to combine this with a 2 layer gasket and ctr cams. this would raise my compression to the 11.6-11.7 range. was gonna tune it wiht probably just a vafc and some 310 injectors (not sure if thats even necessary)
now i was searching on honda-tech and i came across a guy with a gsr block, itr head ported with ctr cams and b16 pistons. with just tuning from a fields vtec controller (stock injectors and fuel pump) he put down 195 whp and 140 trq and he ran a 12.9 on slicks with full interior, impressive. the b16 pistons will yeild a higher compression ratio and will probably eliminate the need for a 2 layer gasket to obtain the same 11.6-11.7 compression range. not to mention the fact that b16 pistons are easier to find and cheaper too. but are they also lighter? what about the strength? and arent the type r pistons coated thermally on the skirts?
just looking for some opinions on which would be a better way to go. the b16 pistons? or the itr pistons? also tuning suggestions are welcome too but i dont plan to go uberdata, hondata or any of that other stuff, just too much hardware for me to worry about. this isnt some full out race project, just a mild build. mostly to be used for daly driving and occasional racing at the track, so reliability of the build will be an issue too.
thanks.
