Walbro DOES NOT make a replacement pump for the '88-91 Civic/CRX. This means that the GSS-342 pump, (and any 190 lph or 255 lph pump within the same chassis family), WILL require modifications to the fuel tank pump bracket and the wiring within the tank.
Jackson Racing used to sell a fuel pump conversion kit for the 4G cars... you might contact them to see if it is still available.
guess ill just get a walbro and do some work with it. im thinking about getting an apexi vafc; is this a wise decision? found a stock of them that are going for $260 shipped, which sounds like a decent price to me. if i had the apexi vafc, would i need the jr map controller? does anyone else have the apexi vafc? how easy is it to use? with an af gauge, could i just tune it with it out of gear in my driveway by reving to 500 rpm increments and adjusting the fuel accordingly?
Even with the VAFC, you will still need a MAP controller. I think the VAFC is a great tool to use if you decide not to go standalone. It's easy to use and easy to install. But you cannot just tune it by revving in 500 rpm increments because your A/F will change when your car is under load (ie. moving). If you're spending a whole lot of money to buy parts, why not just have it dyno tuned?
<font size="2" face="Verdana, Helvetica, sans-serif">im not even sure if my budget will allow a vafc or a map controller. on 6 psi, dyno tuning is not a must. now if i were boosting like 12 psi, i would dyno tune without a doubt. so i can basically go up and down the road and make mental notes of how my af ratio is, right? the nearest dyno is over 2 hrs away also.Quote:
