Say I have a 600whp B series swap sitting here and I own a 94 Civic Hb all stock.

What chassis modifications will need to be made in order to become a true street and strip car and not fall apart in short time?

Thanks guys lookin for positive feedback here!

 

Should have just said I have 600hp lol. I am curious as well because I will be shooting for 400hp with this build and am hoping to drag it

 

none...

traction bar would be usefull tough...

 

Ya, I'd imagine traction bars, and if you plan on racing it, a cage is probably in order. A 600hp civic should run pretty deep into the 10's, and I'd bet over 135, so just save yourself a headache later and do a 10 point in it now with a window net.
