Wouldn't hurt to toss in a Walbro. A guy in my town uses the stock KA24E fuel pump with his SR20DET. It's possible, and I think the fuel pump can handle all the load it gets until the ECU initiates fuel cut. Just keep the stock one, finish the swap, get the car running, and if the fuel pump is lagging, replace it with a Wal-Brosef.Chris90FB240sx said:I was wondering is it required I get a bigger fuel pump for my sr20det motor now? I will be running stock settings for now but even with stock setup will it need a better fuel pump. And please no smart ass comment that some of you like to drop in.
