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?

 

New rotor housings and rotors are a far cry from a motor with 40/50k miles on them. Jspec engines are gamble. I have so for yet to see one that is ready to drop in and go, most of them are just cores.

 

because my cousin blew his jspec two weeks after we had got it installed..

unless you rebuild it

 

Im guessing a its the fact that you know the rebuild will run for a good while...and then with the JSPEC engine its like "dun dun dunnn"

 

thats what i did. buy a jspec and rebuild it. its fairly cheap when you consider how great of shape the housings are in.

 

Ive had 2 jspec 13b-re's with over 100PSI cranking compression from startup

 

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.

 

Who has them for $1000 ?
I need one.

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
