I bought a JDM S5 13BT, and it showed up with the apex seals ground into the rotor housings. So I salvage what I can from the wreak, And start building a new one.



So I buy a set of cermet B coated Rotor housings from JHB performance, Get some porting templates from racingbeat, And street port the housings. Then I cut cooling grooves in the housings water jacket, on and around the "hot spots"..

Both the rotors were toast. So I bought two S6 Rotors. Then polished them up.



Then I street ported the irons, And sent them off to racingbeat to get them lapped. I also sent the whole rotating assembly to racingbeat to have balanced.. I also ported the oil pathways at the oil pump while I has it apart.

All right. I put the 13BT together with a mazda OEM rebuild kit, But I used 93+ side seal springs, side seals and corner seal springs. I also traded out the stock oil control rings springs with some Mazda Factory Race springs.



He is a pic of the stack being put together, and a pic of the engine getting ready to be droped in...

I scored this OS Giken clutch and flywheel from the blown JDM!

awsome

 

looks good man

 

I mounted the engine up, and used some cheap ebay turbo piping for plumbing... At first I vented the the wastgate outside, But it was way to loud. So I welded up a new downpipe for it..

Now that I have it put to gether and running, working out the bugs is going to be the hardest part....

 

sounds pretty cool. how much has all that cost you??

 

I have a bit over $12,000 into my RX... But that is including everything.. My 17 inch rims, tokico HP struts, Racingbeat springs, Poly bushings, engine, stereo. bodywork etc ect.....



If you really want to see what I have done to my car, And how much I have spent on it check out my Registry.
