Race cars are like boats I guess. Time to bust out another thousand.

- Wed Dec 26, 2007 3:25 am #35296 but he did a b20 swap and wouldn't he need a better fuel pump for the increased engine size?

- Wed Dec 26, 2007 5:08 am #35300 The key in this is that he has a B20 VTEC

Cx or CRV or whatever pump isnt gonna keep up with that.

- Wed Dec 26, 2007 2:33 pm #35315 we've always ran stock fuel pump on my bro's car (DX) with all the motors he had in it when we put the 255 walbro in that was a little much but and he had B20Vtec bored to 84.5 (running thin on stock sleeves) and cams p&p and it pulled very good but if you were to upgrade since staying NA 190 walbro should work just fine
