ok i got a question. My bro has been telling me that i need to get a new cross member for my 91 civic hatch, so that the ls will fit nicely in the egine bay. Can someone tell me if this is true. Thanks

 

here i'll help you out.
the only reason you would need a new front crossmember is when you run a 4 to 1 header then you would have more clearance for the header, or you might be running a traction bar. but the stock front crossmember should be fine just remember to cut the front mount off.

 

ok im not doing the swap, a friend of mine is doing it for me. I was thinking of getting a traction bar for future reasons. Thanks
