Premium gas of course for best performance
Yes however it requires much more than just the turbo to be swapped. here is a pretty complete list. Compliments of 3si.org Parts list: -Turbos from a VR4, either the TD04 9b's or TD04 13G's with wastegate actuators -Both intercooler and all piping associated -Exhuast manifolds and the manifold gaskets from a VR4 -o2 housings and precats from a VR4 -Oil housing from a VR4 -Oil feed and return lines for the turbos, and all the eyebolts and gaskets -"Joint" on the back of the engine block for the rear oil feed line -Modified non-turbo oil pan to accept oil return lines -Water housing from a VR4 -Water feed and return lines for the turbos and all the eyebolts, washers, and gaskets -VR4 downpipe -360cc injectors -VR4 fuel pump (or walbro 255ltr/hr) -Injector resistor pack -Front motor mount bracket -Oil cooler with lines electronics needed: -S-AFC or S-AFR -Boost gauge -Air/Fuel ratio gauge -Exhuast Gas Temperature gauge (two is best, one for front bank and one for rear bank)
20 gallons, premium(not joking)
93 octane all the way!
91 octane there should also be a sticker inside the fuel door that will tell you what the cars requirement is
idle control valve
absolutely, if you first convert the engine to run a turbo, and that would include replacing your 4spd automatic with a manual gearbox, considering the automatic transmission that come with the sl & base models could barely handle the v6 engine alone. I would assume adding another 10lbs of boost would probably burn it up pretty quick. personally i would recommend selling your sl for a vr4 model, considering the price for the conversion would probably be more expensive than just selling the sl and buying a vr-4, but hey it's your money, not mine. Above is 100% correct just to push the point further here is a list of parts needed to swap: -Turbos from a VR4, either the TD04 9b's or TD04 13G's with wastegate actuators -Both intercooler and all piping associated -Exhuast manifolds and the manifold gaskets from a VR4 -o2 housings and precats from a VR4 -Oil housing from a VR4 -Oil feed and return lines for the turbos, and all the eyebolts and gaskets -"Joint" on the back of the engine block for the rear oil feed line -Modified non-turbo oil pan to accept oil return lines -Water housing from a VR4 -Water feed and return lines for the turbos and all the eyebolts, washers, and gaskets -VR4 downpipe -360cc injectors -VR4 fuel pump (or walbro 255ltr/hr) -Injector resistor pack -Front motor mount bracket -Oil cooler with lines electronics needed: -S-AFC or S-AFR -Boost gauge -Air/Fuel ratio gauge -Exhuast Gas Temperature gauge (two is best, one for front bank and one for rear bank)
Green gas is green gas. It doesn't matter
The Mitsubishi 3000GT VR4 (Twin Turbo model) does NOT get good mileage in town, though it is acceptable on the highway. I get about 15 city 28 hwy, my car isn't stock though and probably would use less in the city without the turbo/fuel upgrades for a car with over 400 horsepower the mileage isn't bad, but for being a 3.0 v6 it isn't good depends on how you look at it
87 octane should be sufficient
Unleaded regular
Yes, this engine requires Premium fuel. Using Regular fuel will cause pinging and engine damage.
Nobody seems to know the answer, so type in this question: What is in gas that pollute the air? That should help answer your question!!!
