The compression ratio is generally what hurts the gas mileage on a turbo car.
The TBI intake isn't very good but overall it is a much better system. It isn't necessarily that carbs are always bad, but the ones that came on these cars were... With a TBI conversion you just swap the intake and exhaust manifolds and keep the engine the same. Wiring(hood and dash), the TBI injector/airbox, and fuel tank, and probably the alternator (which should be changed anyway to the newer nipondenso alternator anywway) would also have to change. It is a lot of work. It would however be capable of something that the carb cars werent... Running well in both hot and cold weather without adjustments! -Rich On Fri, 11 Jan 2008, [EMAIL PROTECTED] wrote: > Date: Fri, 11 Jan 2008 18:13:45 +0000 > From: [EMAIL PROTECTED] > To: Rich Bryant <[EMAIL PROTECTED]>, [EMAIL PROTECTED] > Cc: shelbydodge@imagilist.com > Subject: Re: SD> need help with omni > > Changing to TBI would be more reliable, but I think the milage would suffer a > bit.
