I am unsure of specs but i'd imagine you should be able to run a stock gze on the pump your talking about. However i would be seriously considering getting it upgraded cause you dont wanna have your motor lean out and shit itself for the sake of $300 bucks max for a bigger pump.
Do some research on the net and find out how much a stock gze pump can flow and how much a stock corolla pump can flow and compare the difference. Either that or ring repco and ask for a replacement corolla pump and get the model number for a bosch one, that should make finding flow volume easier.
A friend of mine had a 1jz in a cressida running on a stock pump and it was fine. He's a little dodgier than i am and in my opinion i'd buy a bigger pump. It will be one thing less you'll have to worry about either playing up or should your engine have problems youll know it wont be the pump - provided you set it up right.
Google should be able to find your answers
