I htink its "around" 1k bucks. Its not very recomended by shops here in the US.

 

that much? wow

 

Why not. It helps to strenthen the housings.. I don't see why that would be bad. was done on my engine at no extra cost.

 

if your engine is gonna be pumping out a lot of horsepower its worth it

 

How does it strengthen the housings? You take material out of your housings to create the dowel pin holes (or enlarge the present holes as some folks do).
I would imagine that it weakens the actual structual integrity of the housings alone (not assembled).

It does help fortify the overall structure of the engine due.

Sorry to knitpick.

I was told by chris at rp that it doesnt help you from detenation, it preventd you ******* up all kinds of **** in your engine when you detenate. The average Joe rotary engine builder cant do it. I was told that the only peep's around the us that can do a good dowel pinning job is below the border of the us(not sure about this though) also if you trash a rotor when detenating then guess what, another dowel pining joby. Save yourself some money and use mazda 2mm seals, they work the best.
