I'm stepping up to a 75mm tb and 76mm sensor. 38# injectors. I have a stock(but new) fuel pump in it. Not sure what stock flow rate is, but will it be enough or do i want to get a bigger pump?? Only other mods are 10% od sc pulley and mod exhaust. K&N air filter.
If you have an 89-93 SC, I don't think the stock pump is big enough. If upgrading the pump get a 255 lph hi pressure pump and it will give you plenty of room for future growth.
