I am looking at putting a 3.4 pulley on my 98 SSEi. I am just trying to get an idea of what kind of other upgrades are recommended to complete this modification. I already have a 180 thermostat, custom exhaust, (mufflers deleted, custom resonator) hollowed out the air box and fitted it with a K&N, and have the boost solenoid in its optimum location. The car is my daily driver and i tend to drive it pretty normally. (Most of the time
) I already took into consideration that i will have to go with a 71.5 blower belt or upsize to a 3.5" tensioner pulley. This should pretty much cover it I would think but i want to get some ideas before i dive in.
