My motor in my tII blew on me. I need to get my car running asap. Should I get one rebiult or get a jdm one? It seems much cheaper to get a used engine than to get one rebuilt. Does anyone know of a reliable source of good used engines of rebiulders that i could get to in nyc? thanks for your help

Your most likely going to want to rebuild the JDM engine, so save your self the trouble and cash and rebuild your current motor.. might end costing the same and you will have a engine that will run for anouther 80k+ miles. Rather then an engine that might blow few hundred miles down the line. JDM engine is just a junk yard motor from Japan.

Same deal here.
I didnt' blow up my motor yet. Just getting ready for the worse.

Im thinking about a REBUILT or a "Low Mileage" Good Compression Swap.

I think the REBUILT has more advantages if it's built well.
• It's gonna be clean in & out with new seals, porting to if desired, etc. etc.
• The swap is kind of like taking a chance, but I think is cheaper.

Towards time, I'm leaning to the good "REBUILT.
It's just the thought and feeling of "FRESH" rotary engine. free of carbon and ****, smooth revving, etc. etc.

I don't know myself where I can find a shop who does rotary rebuilds or sells rotary engines, wheter JDM or not.

JDM DEPOT
I don't know if they are from Kerny, NJ
I'm also hearing good things about this Man: Kevin from ROTARY RESURRECTION
I'm thinking about stripping mine to short block and ship it out.
We'll see...

There aren't any in NY?

You seem surprised that an engine that has been rebuilt to near-new condition is more expensive than one that is in an unknown condition, with probably understated mileage and that may have seen sitting in a yard filling with water before being shipped...

The decision somes down to money. If you can afford a rebuild, get one. If you can't, get a used one.

This is true, but if you have the option to, your best bet would be to (upon assesment of your internals) buy a JDM engine and rebuild it, so you get the luxury of low mileage housings, irons, rotors, etc... Sure the springs are probably stuck, and the motor will likely have relatively poor compression, but who buys a Jspec and just throws it in there anyways? It's simply a rule of thumb that you should rebuild the Jspec before using it... You'll be rewarded with a low mileage rebuilt core though, which IMO is worth it...

You're assuming the engine is actually low-mileage. Why would it be? Why would the fact that it came from Japan make it likely to have lower mileage? It doesn't matter where the engine was first sold, it's still anywhere from 15 to 20 years old.

i believe their smog laws prohibit engines from being on the road with more than 30k miles, or so i was told but they still have been in storage for a decade which isn't a good thing for the rubber seals and apex seals which tend to rust or carbon stick to the rotors.

the least expensive rebuild's from a reputal source that i am familar with is rotaryressurection. and the rebuild prices there are right around the same price you would pay for a jspec

if going to tn is to much for you, or shipping is to expensive, the importer that i used for my cosmo engine is located in NY. i dont have a phone #, however a thread with what he is selling is on nopistons here http://www.nopistons.com/forums/inde...howtopic=44149

Myth.

J-specs can make good cores for rebuilds, but we have cracked them open to find parts that were unuseable. Anywhere from bad housings and rotors to complete oil starvation, which takes out the irons as well as the rotors.

Previous posters are correct, the engines are still nearly 20 years old, even if they were stored really well, sitting is the worse thing for any engine. The seals dry out, steel starts to rust, and corrosion on aluminum parts.

Engines from Japan are more likely to have low mileage parts than a USDM engine... Here in the USA, people drive the **** out of them for 150k+ miles usually... Over there THEY DO have certain laws that try to prevent high mileage vehicles from becoming registered for street use, which doesn't ALWAYS mean you get a low mileage engine, but it greatly tips the odds in your favor... Not every Jspec I've pulled apart had perfect internals, but about 80% of them were perfect inside... Of course the seals will all be stuck and the soft seals will be garbage... That's why you don't even try to start it... Just tear it down right off gate and inspect it...

Sometimes I think you like arguing just to hear yourself type... LOL

throw in an LS1 V8 and be done with it.

I purchased a used engine 'from Japan' many years ago. Things might have changed since then, but I was assured it was a low mileage engine.

Not having the funds to do a rebuild, I poped that engine into my '80 and was off and running.

10K miles later, I needed a new engine again. At this point, based on that experience, I would never buy a JDM again.

13b4me

Case in point... The engine probably had good internals and bad soft seals and/or apex seal springs, side seal springs, etc... Exactly why you DON'T buy a Jspec without planning to rebuild it...

All I'm saying it 9 times out of 10, a Jspec is a far better rebuild candidate than a USDM engine...

Thanks alot for everyones help. Since i'm only a few hundred shy of all i need for a rebiult and ported engine from T&R which is in ny, I'll be getting my baby towed over there, torn down inspected and baisically taken from there. If my internals are unusable i'll have to buy one of his rebiult motors. I hope they'll let me chill while they tear it down cause i'd love to do it myself. **** if i didnt live in nyc I wouldnt have such a hard time cause i'd tear it down and rebiuld it myself. It really doesnt seem so hard with the right tools and a few homies. Thanks again and i'll let you know how it goes.

exactly only retarted people put v8s in 7's. Why would someone buy a 7 and take out it's sexy motor to put a pig in its place

BoostedRex

Save yourself the frustration and cash and just rebuild your motor. Because like everyone else has said, most JDM engines that people buy have to be rebuilt right off the bat anyway.
