Question about 12A housing strength at higher HP levels (300RWHP)

Can the stock 12A rotor housings hold that much power without doweling or other mods? My rotors will be clearanced and balanced and I will be running hardened stationary gears and oil upgrades but I'm worried about the housings. I want to run a T04B setup in the future.

get a set of the 20b tension bolts, they are thicker (you will need to retap your front plate) and they barely fit through the stock tension bolt holes, its like a poor mans way of doweling the motor without the extra costs

NOTE: 20b has two (2) sets of tension bolts, fronts, and rears the rear ones are the one you want = same length as 13b units and will need to be shortened approx 20 mm (= .7878")

20B parts seem like they may be a bit pricey and hard to find. I will look into it though. Also, by shortening the bolts, won't that remove most of the threads? Probably have to re-thread the bolts.

Actually the threads are way to long anyways, and the price is the same as the 13b components, just a different parts number.

I will look up the parts number next time I am at the Kanagawa stealership.
