Why buy new rotors and housing for a rebuild when a low mileage JSPEC is cheaper?
Exactly like the title says ... a jspec s5 t2 engine can be had for aronud 1000 bucks with around 40-50k on it. The housings and rotors are generally in great condition (although the seals may not be). Wouldn't it make more sense to buy this engine for the parts and use it in your engine thats being rebuilt?
Or am I just completely missing something? You would also be able to sell parts off from the JSPEC engine when you were done with it ... so I dont understand why more people dont do it?

I've wondered the same thing. As long as you can verify that the engine didn't eat a seal, then its the most economical way to get your engine running if you need to replace major parts. J-specs are usually excellent candidates for rebuilds, just don't try dropping them straight in the car.

All the j-specs ive used (4-5) Worked great! Ive often asked myself the same question. I guess if you dont want your internals to be stock might be a reason??

A rebuilt motor, by a knowledgable builder, will out last and run longer than a used engine.
In most or some cases the rotors and side housings are in good condition and can be reused. All needed for a rebuild is the seals, springs, and rotor housings, which runs approximately/closely to a Jspec after shipping. But its not a used engine w/ unknown exact milage or condition.
I would agree they're good for cores.

because having the peace of mind is better than driving the last 2/3 of the motors life cycle.....
i agree they do serve the purpose of being a great core!
i've had to disassemble and clean and inspect 6 J-spec s4/s5 motors for a friend of mine who was going to build a few race motors and all the irons and rotors looked almost new after some deep cleaning and lapping the irons. the rotor housings didnt fair too well as they had significant cracks in the plug holes and showed early signs of major flaking
