Also, can someone give me the building specs for RX8 motors?? Ie what the end play, side seal spec, etc..

Thank you!

Phil, what caused that scratch? To answer your question as long as it isnt a high spot you can run it, may not be ideal but it will run. You see very slight difference in compression on used irons unless they are just extremely worn. I dont remember the clearances on the renesis but they have a much larger clearance from the factory than the 13b. Landers has a good bit of experience with these engines and I am sure he can chime in.

I think its caused by a blown apex seal. The front rotor housing is shot and all three apex seals from the front rotor are gone.

I bought a spare rotor housing from Kevin.. and I think its useable but just wanted to get some opinions. I'm just wanting a spare motor in hand just in case if mine decides to go..

How many miles do you have the current motor Phil? Ya know you're covered 8yr/100k on the motor?

[Herblenny]

My currently motor has been replaced before and my car now has 120K.

But the engine only has about 30-40K... I don' t think they will replace it.

No, your out of warranty. I forgot you had that many miles. You could always bridge the extra motor, there are some great things being talk about over on the 8club about a few bridged Rennys. I'm looking for a short block to start playing with, I've got 45k on this motor, 76k on the car.

[Herblenny]

Bridged Renny? Hmm.. What are some of the benefits??

One thing I noticed was the side seal clearance. That thing has about 15 thousands of play.. Do you know why??

And can anyone have specs on this engine??

[Herblenny]

I found this FSM

but the "03. Engine Detail" pdf does not work.. Can anyone help?

[I8U]

I haven't been keeping a close eye on the ins and outs but it has been done and was successful.
