I've been reading quite a few threads about replacing the boost pipes and there's a lot of info on replacing the top pipe but not a lot on the lower.

 

Can anyone tell me (or post the links) what I will need to replace the lower boost pipe.

 

what size couplers will I need?

is it a 90 degree bend?

 

thanks in advance

I think it's very tricky to do! I've searched constantly for the solution to the bottom pipes but gave up in the end! I think it's because the bend is slightly tighter than ninety degrees!

 

two 51mm silicone bends 90degree, couplers where 60-51mm and a 50-51mm both couplers bought from creationsmotorsport_uk on ebay, the metal pipe my old man got from his work thats a 90 bend 51mm .  the silicone bends need a lot of cutting down to fit.  First time i tried the car the coupler on the bottom of the intercooler popped out this was due to me not cutting the silicone hose back far enough which was not allowing the coupler to sit in correctly. This had now been sorted and has not popped off again 

 

 

After i done my top boost pipe and seeing how bad my bottom one was i decided to make my own bottom one up here's a few pictures of how it looks

these pictures where taken while i was making sure it all fitted ok
