Im in the process of installing a cxracing 76mm turbo with a 1.15 A/R on my truck. Im rumning a set of kb-racing 3.5" down pipe. My only problem is the exhauat side of the turbo is measuring at 5" OD do they make something that will nexk it down so it will fit?

 

I don't think you will find an adapter to neck your turbo up to a 5" and still fit properly. You will probably have to get another DP or step up your game with a bigger turbo.

 

Ya, thays kinda what i was afraid of. I just didn't know if there was something out there that would neck it down

 

Ok i stand corrected the OD of the nack of the turbo is 4.5"down and the ID is 3.5 "

 

If its the garret flange style a 3.5" vband should work.

 

Idk how to describe it. The inside diamator is 3.5"but just lokt the down pipe. But the lip of the flange us 4.5" it looks as if a 4" clamp would possably fit. But it wouls still be bigger than the DP? I just got a new computer so we dont have internet at the moment so i cant post pictures.

 

I am pretty sure when vbands are listed, they are listed by the pipe ID only. The outer flange areas will be larger than its listed size. So if its a 3.5" ID, it should be a 3.5" vband. Since you already have the 3.5" DP, why dont you just put them up to each other and see if they fit...

 

^ yea just hold it up to the turbo and look at it. Just make sure the difference between the flange and the lip of the flange on both the turbo and DP are the same or it won't seal properly.

 

Ill have to see if i can get a picture on here some how. I get what your saying. But the lips alot bigger than the Downpipe
