Couple thoughts hit me real quick. 196's don't have the most stable head gaskets as-is, so are we talking O-rings and or possibly copper gaskets to get even 5 lbs of boost to work? Second thought is, would you even want to increase the pipe size to the turbo? Would not the stock 1 3/4" pipe keep the velocity up better? This also saves on costs. -- Mark Price Morgantown, WV 1969 AMC Rambler, 4.0L, EFI, T-5 2004 Grand Cherokee Laredo, 4.7L, Quadratrc II " Chronic Pain Hurts" -------------- Original message ---------------------- From: Brien Tourville <hh7x@xxxxxxxxxxxxx> > From: Frank Swygert <farna@xxxxxxx> > Subject: Re: [Amc-list] rear mount turbo > To: amc-list@xxxxxxxxxxxx > Message-ID: <4767178D.7090507@xxxxxxx> > Content-Type: text/plain; charset=ISO-8859-1; format=flowed > > I did the research for the article in AMC!!
