yeah, propably getting the prp brace or a billet main/girdle set from spool.

Why so rude? Because you are talking to me.like im a child... I dont have experience with rb30s yet so that is why im asking about it?? And no i havent decided yet obviously why the f**k would i even ask if i had.

Okay so you obviously have never heard of gtrs cracking blocks... Obviously im going to grout fill it why the f**k are you so hostile? Most of these engines are in 4wd applications atleast the ones i've seen in gtrs. They have a prp girdle in most of them for the 4wd conversion and for the strenght. But some people dont use one also some running the sohc rb30s at 1200hp with stocl girdle..... Oil pan has nothing to do with stock main cap streght btw.

Because theres a diff in the oil pan? pretty sure thats what everyone says when you add power to a gtr that it might crack the block from twisting it because of the diff... i know they do and prp does but what im asking is do i need one for the power im aiming for in a rwd application.

Hello! Wasn't able to find info on this anywhere other than seeing some youtube dyno videos. So i am in the process of building a rb34 stroker with 25 head for my s13 street/drag car and i was wondering how much power i will be ok for with the stock main cap girdle? My goal is 1100-1200 crank hp, ive seen some on yt running around that with the stock girdle. Also as this is a 2wd setup it wont flex the block as much on lauches as a 4wd would? Im gonna have arp 2k main studs and line bored.
