Preludesi2.1 Posted October 1, 2009 Share Posted October 1, 2009 i have a 90 prelude si b21a, someone told me that if i put the b20a5 head on the b21 block that i would get more compression. i dont know if thats true or not, and where can i find a turbo kit for the b21, aftermarket parts for this car seem to be non existent except pace setter header lol, any1 have any ideas?
