I have a buddt who threw a rod in his prelude several months ago. we have had many problems trying to locate new, and even used parts to rebuild his engine. We have decided to go ahead and drop on an H22A4 just like the engine in my 5th gen and we would like to know about anyone who has done it, how hard it is, what parts we need, and where to ge them. All information would be greatly appreciated
