Re: LS turbo advice needed...

Kind of assumed you need one in the downpipe but was thinking you don't really need 2 since there will only be one exhaust pipe.

The turbos I have been looking at are the VS billet 7875, the Huron Speed billet 7875, and the Precision LS cast 7675. The price gap is a consideration but I definitely want a setup that will last a while.
Mine isn't running yet so just my two cents.

I am planning on running 80's and have a walbro 450 in my tank. I plan on running a wideband just to monitor my stuff. I am running one O2 sensor in the down pipe. I got a GT45 for free so that is what I am using. I was planning on buying a case VS 75mm prior to getting my turbo.
