yes, so as the title states id very much like to know how much hp can a stock 13b turbo support?

 

i guess this would depend on how reliable and how long you would want it to last... haha if you want it reliable well. i dunno much about the 13b but maybe 300-350whp-ish... if you wanted more, say 400-450, i think the 20b?(not sure if thats right) might be where you want to go....


but i know almost nothing about rotary and im still trying to look into it more.

I hope to hear this soon!

 

it all depends on the series engine. what series 13B are you inquiring for. It also depends what bolt ons you add to it. ive heard about S5's TII's pushing near 500 HP on stock ports. So if youre a little more clear in your question i might be able to give you a better answer. however since you are new to the forum ill let you know there is a search button on the top right of the page which is very useful.
