i have herd that b20b oil pumps are the same as gsr and itr....is that true?? they even have the same part number too.....somethin like 1500 something p72 bahbahbah.... and i was wondering if the b16a oil pump will be good enough for a lsvtec w/ ctr pistons setup??

 

its fine that will work. you can take out the cover and use a fueler gauge to check to see if the oil pump is still good
