If i were to rebuild my engine. Does ta mean i have to dyno tune my car again?

 

If you change the porting, yes. I would say that having it returned regardless would be a good idea but you could probably get away with not doing it if everything else stays the same.

 

Where is the "porting" located on the engine? I'm trying to get an idea if my street port would carry over during a rebuild or not.


Thanks

 

Intake porting is on the irons. Exhaust porting is on the rotor housing.

 

If it is apex seal failure you may want to consider a retune anyway

 

If one was to spend 2K+ on a rebuild why the hell wouldn't they just spend the few $$$ more to DO IT RIGHT and be thorough??? The "tune" is SOO important that I would without a doubt be going over it again. Things could and do change durring the R&R of the engine...you just don't know.
