i have a 1st gen b16a motor in my crx and i have a spare b16a sirII block in the house... if i was to mess up the block in my car, can i switch the sirII block in without any problems? or will i need to switch my ecu to obd1? just a quick question because if i have to do more mods, ill probably just sell that sirII block and get a first gen one....

 

the block will work fine with no problems

 

so its a straight drop in right? no other mods whatsoever?

 

yep bolts straight on..no other work needed

 

thanx guys for the help... i was about 2 trade the block too with someone who had a 1st gen block...thank god i asked questions first
