I have intercooler piping that came out of a 00 hatch with b18c1 and im just wondering if anyone knows how well it will fit into my 99 civic si ? is it gona fit perfect or do you think it will need to be modified a little.

Also same deal with my down pipe, from a 00hatch going into EM1, i donno if its gonna end up being a little short?

 

Its the same car.
I dont see why it wouldnt work.
Downpipe might make a difference though

 

anyone else know about this ?or done this ?

 

thats what I was thinking...

BUT the Gs-r and the B16 have totally different intake manifolds so you might want to consider that ...

 

You may have to cut a little bit to get it to fit, but if so, it won't be much. Also, one thing to consider, as was previously mentioned, is the difference in placement of the stock GSR intake manifold vs the B16's IM. No offense, but IC piping is a cake walk and you really shouldn't worry about it too much...Hell, i've always just made my own
