i know it is too late for you now, but it is a good read none-the-less...

(AND SHOULD BE REQUIRED READING FOR ANYONE BUILDING A B20)

[Alexx]

Thanks, I have read that article yes.

I should rephrase, what do you mean by brace the crank? - I assume girdle? My mistake, i believe mine is not braced if that is what you are referring to. Correction from what I said before.

I am using arp main studs with the factory main caps.

[tinkerbell]

yes, there is only one way to brace the crank, and that is with some form of girdle...

no...

[ericl33]

no...

in one sentence, what situation would require one?>

[tinkerbell]

any situation where the person decides that for their intended purposes they would like to add additional strength to the bottom end to make sure it stays together...

this is for when you are getting really serious:



this is 300kW+ territory

[ericl33]

more information than needed, but appreciated anyway.

Dave what are your thoughts regarding my theory of the some batch of OEM B20 bores having irregular looking bores which often cause them more prone to crack.

ie.

The top of the bore circumference is a lot thinner than the rest ....
