Cost and time. It looks way cheaper to buy a JDM than to rebuild. under a grand for a complete engine vs around 2 grand for a rebuild. And how hard is it to get a short block and bolt on the heads?

Thanks. Do you know of anywhere that I can find what heads form what engine models and what years match?

I have a custom built 1996 ej25 turbo that is broken. The crank pulley wobbles, knocking sound in the case. The motor is in my 1974 Westfalia conversion. That being said, Id like to replace it with a JDM. Im open to an ej20, ej22 or ej25. Id like to essentially do a long block swap with all my existing stuff, minus the turbo if need be. Is there a reference data base or web site of what motors and what years use the same exhaust manifolds/headers, same intake manifold bolt positions etc. etc.? Basically, do the heads have the same bolt patterns? Please advise
