thats pretty interesting, I too would like to see some testing to find out what kind of difference it really makes.

Considering that's $14 AUS more than what Mazdatrix wants for a set of stock bolts that's pretty cheap. I doubt you can get them made yourself for that unless someone cuts you a huge deal.



I think it will cost that much again to have all the machining done to make them fit.



I think it's pretty interesting though. https://www.nopistons.com/forums/pub..._DIR#>/dry.png
Yea I relized the price was pretty good after all the process they have them go through too.

Why would you want your engine to twist some? Whats the reasoning behind that. The way i look at it is, if the engine is flexing you are losing clearances that are supose to be maintained. This will cause increased ware.

Similar to how you don't want your chassis to flex.

But i could be wrong.
theoretically yes, but the engine is at various different temps (ie it expands and contracts) so you need to give it a little freedom to move around. the idea behind the clearances cold, is so that they go away when the motor heats up, but not to the point where things bind

how important is this mod anyways?



wont you blow an apex seal before you twist the engine

No, not necessarily.

Someone should call up ARP and have them make a stud kit for the 13b. Would probably come out substantially cheaper than the aussie counterparts.

BigTurbo74 03-06-2004 01:50 AM
if i remember right arp was thinking about coming out something for our engines but i don't know if they decided on it.

TheCamel 03-06-2004 06:31 AM
we would have to show a definate intrest in order to get ARP to design a kit. I have thought about contacting them, but to do the R & D for this kit, they would need a market of more than just 5 people, if you could get 100 intrested in such a product, or show there was a market for them, they might be more inclined to produce such a kit.
