i may get flamed for this but
will a gsr header fit on a ls motor


b/c if i am not mistaking all the b-series have the same bolt patterns on the heads?


thanks

 

It will bolt up to the head, but not to the cat.

 

Yes, a vetc head will bolt right up to an ls bottom end. The only obsacle you may encounter is variations with the v-tec. The v-tec needs an oil line from the block to the head which is offered on gsr blocks, not ls. The advantage of an ls bottom end is longer stroke and more suitable compreesion ratios for turbo. Search around for ls/vtec conversions, preferably on ebay. Also, sheck out this site for helpfull hints on this build, I am doing somthing very similar and find this to be quite helpfull.

he didnt want info on ls/vtec- he just wanted to know if a gsr header will bolt up to the ls

and to answer your question--furious94ls is right
it wont bolt up to your ls cat

 

if its a 00-01 gsr header it will fit with no problems

 

well i have a 90 civic si
with a ls swap

so i will have to make a pipe or something anyway
is the gsr header longer or shorter then a ls header?

but the question is the header will fit under the block and bolt to the head


thanks

yes

 

actually since you clarified, you don't need to worry about what year gsr header is for since you will have to customize your exhaust to fit properly anyway

 

well the kewl thing is that civic exhaust had to be forced back about 6 inch to make it fit the stock ls manifold

so if it shorter then it might bolt right up

what do you guys think

 

the difference in lengths of the headers is not that great. the cheapest and easiest solution for you would to take it to an exhaust shop and have them chop off 6 inches of your exhaust at the flange closest to the cat

 

i will weld some up myself b/c i love to weld
but i was just wondering b/c i buy this header from my buddy that is going turbo


thanks
for your help

 

is the header you're considering buying a stock gsr header? if so, its probably not worth it to swap out the ls for it. if its an aftermarket header, i would consider it since it would probably flows better than stock

 

yes its a dc sport header

i am getting the header for really cheap

do you think it will open the car up?
