I recently blew my motor at 93k (on monday), and I am currently looking at options for a replacement.
Currently Im thinking of trading in my core for a REman engine from Malloy mazda for $1950. I also want a very large stree port as I will be running a Single turbo setup. My question is -
Can I reuse the seals in the motor after its been pulled apart for porting. Or am I going to need some new seals after porting to put the motor back together. If I need new seals whick ones will I have to replace?

Any assistance anyone can provide would be greatly appreciated.

 

You can keep the seals as they are brand new with the rebuild from mazda

 

You may want to buy some new water seals just in case you mess up any of the old ones.

 

yea, take it apart carefully and you will be fine

 

Any on eknow where i can find instructions on how to tear down and rebuild a block.

 

hmmmm, block tear down instructions... Im not sure if there is a write up on the net. Its pretty self explanatory. Maybe I will take some pics and writ up a webpage this week when I tear down my TII motor.

 

Check with the factory manuals: http://www.iluvmyrx7.com/3rd_gen_manuals.htm

 

Do you know the condition of your stock motor..? If you buy a remanufactured motor you need new water gaskets, front cover, dowell pins etc..also the original seals in the reman have to go back in the same slots/places they came out of so mark them. There are also some upgrades you may want to do if you tear the block down (oil and water) along with the porting. Lastly, remember you will lose your warranty from mazda as soon as the block comes apart...
