Anyone got pics of there setups? my first plan is to run the cast manifold (16vt) and get an adaptor milled and cold welded in as I have a friend who can do this. Anything to watch for/advice. Do they make that much difference - i have heard they have excellent boost control, better spooling even than a EBC as the internal wastegate interfer with the flow of the turbine on a standard setup. also heard they always run what boost is set regardles of air temp and stop boost spiking etc

Don't think so - you may be able to make up an adaptor just before the turbo but generally it is either a custom manifold or getting a pipe welded into the cast one.

Anonymous Unregistered A	having it welded onto the manifold, as mentioned,...will it either strenghten the manifold (since it cracks pretty easily) or just makes it worse? manifold does seem delicate to me, that's y i'd rather not to have it welded on it....any other solution?

I have only found one company doing this and it isn't cheap either Originally Posted by Jonny - After being taken out at Spa Your car is Usain Bolt with wellies

Will it take the extra weight, will it crack, is it in the right place etc... Also your then using a stock manifold with ext. wastegate where as if your going ext wastegate for power, you may as well get a tubular manifold at the same time Originally Posted by Jonny - After being taken out at Spa Your car is Usain Bolt with wellies

Anonymous Unregistered A	alright..gotcha! i don't plan to change my turbo as yet... so i guess, under such circumstances, i've got no choice but to weld it onto the manifold....if ever i decided to go with external wastegate.... am i right?

Anonymous Unregistered A	Thats not an actual external wastegate though,its only a pipe from the internal one that is re-routed back into the turbo/exhaust down pipe. Last edited by paddy147; 03/05/2006 02:23.

Anonymous Unregistered A	Massive HKS external wastegate on my mechanic,s 800bhp GTR Skyline is so loud that it needs it,s own pipework and back box to quieten it down.This beast of a car is one loud,flame spitting mother of a car to be in on full boost.This car is so loud inside it with the huge HKS turbo and wastegate that Robbie had to install an intercommsystem to talk to his passengers.I had the privilage of getting out in her for 10 laps in Mondello Park yesterday. The smaller exhaust backbox on the right of the pic is for the wastegate. http://i3.photobucket.com/albums/y92/alfa147turbo/MVC-008cS.jpg http://i3.photobucket.com/albums/y92/alfa147turbo/MVC-014Sqe.jpg Last edited by paddy147; 03/05/2006 03:31.

And no that isn't standard cs - its a tubular custom manifold
