if ur deadset on putting something to stop the pipe coming off tig weld a small weld onto the outside in a flew places failing that turn ur mig down low and put like a 2mm bead on it and just run a flap wheel over it so its not too sharp.

i remeber something when reading up on flaring, with aluminium it does tend to split so you might be better of with the weld slag option on the outer pipe for the same purpose. Brass does something similar when flared too.

Also keep in mind only has to be a slight flare not huge so the pipe still stays on. but this may effect air flow ever so slightly if done incorrectly in theory creating turbulence of the air flow.

yeh supercharger off and replacing with a turbo

what are you doing
are you turbo the gze
or
taking the supercharger off and going single turbo

cheers for the replies, swarf shouldnt be a problem if I'm careful about it.

I'm not going to run it with no bead, I was just wondering which is the best way. I was planning to just put a little flare on the end with a cone/ball shaped object slightly larger than 2", but was worried about the alloy pipe cracking rather than flaring...

Just offering my opion guys

i havent blew 1 yet and i have a twin turbo v8 and a turbo 4banger(datsun)

and the coolers this guy is talking about are mounted on top of engine close to tb

ive seen them in the wrong possition before such as on other side of cooler
depends if you want for looks or performance

unless ur runing huge boost the pipes will be fine i have nothing on mine and have run 18 psi before with just normal hose clamps, as long as theres a fair 20-30mm inside the hose it will be cool. as for the i/c mounted bov if ypoure going to do it make sure u stop swarf getting into the core coz its going to be hard to see whether its all out id steer clear myself, and just not have a bov never had any problems without one and makes a tough sound too.

Ive seen bov off valves mounted directly to an end tank and dont see why it would affect the way it functions as this is what wrx's and gtir pulsars have from standard. As far as piping go's definalty have a few beads of weld or have a exhaust shop roll a lip on your piping a was forever blowing of hose's until a had it done

Its a custom cooler with a nice large flat area on the end tanks, would be heaps easier to cut a hole in that and have my rb25det adapter welded to that than to have it welded to a 2" pipe (i'm thinking cheaply here ) I realise they work best close to TB, but I've seen them on the turbo side a lot so I'm sure 20cm wont make a huge difference.

If I "dont touch" the piping will it not just blow off under boost????
