I wasn't saying all J-spec motors come that way. I was merely talking about the motor in my garage. I have seen the housings, apex seals, the rotors, and so forth. I believe I got very lucky in the condition of my motor in comparision to some others. It's definitely a gamble.

Well then, let's change the subject of this thread to a list of Good, Reputable engine suppliers *anywhere*, since engines seem to be what we're asking about.






How about no. Its a lot easier to find information on engine builders, but I havent seen much information on j-spec vendors except the occasional thread in the vendor feedback sections.



It is good to remind everyone that j-specs are junkyard motors. Its a used engine, and its probably lived a hard life. But that isnt the point of this thread, merely a footnote.



The purpose of this thread is a source for those who already decided a j-spec fits their needs, and need to find a good vendor to get them from.

if you dont make a claim on a j-spec engines once you get it, your out of luck, probably why Pettit inspects thier engines once they get them, and like I will do on any future engines.








FYI - Not that its very important. Pettit does not inspect the 20B's they get from Japan. They tear them down and rebuild them. Next time I am there I will ask, pecentage wise, what they felt was a good engine vs. a "done" engine.



They will not go through thte trouble of a 20B conversion with a used engine. The 20B's are purely considered cores.

if I was a shop selling 20b conversions I would not install used ones either, that goes without saying!



no matter how much you warn people, if something happens its your shop's name on the swap

theres a big difference between a jspec 20b and a 13bt or 13brew



all 20bs were automatic high priced luxury cars, where only the fairly wealthy could afford them

the 13bt and rew were from a midpriced sportscar

the 20b should always have less wear, theyre also fairly mild in power from the factory

Logically this would make sense Node, BUT. I have personally been involved with 20B and 13BRE's and every one I got ahold of had at least one bad rotor.



You are $$$$ ahead to at least pop open every Jspec and renew the software and seals. We all know Rotarys do not like to sit

Just pick up the phone book, most large cities have engine importers are probably a lot cheaper than buying over the internet. Ofcourse you may be taking more a chance, but most places offer you 30 day guarentees.

seal/rebuild kits are about $1000 now, hadly that cheap



I think most jspec buyers are NA-TII swappers, I guess the theory is lets get the thing swapped and running, if a coolant seal goes then rebuild it.
