I have my boosted crx at 8psi but i want to go up to 11psi safely, my question are wich walbro 255 need to buy, i read about 2 different types, hi and low pressure, wich one i need to buy for my '90 CRX DX.

Also i read walbro fuel pumps are for hondas starting at '92, theres any difference with my fuel pump or something? or i need to do some mods to make it fit?

Get the High PSI and Fuel Pressure Regulator. And they do have a 88-91 Application.

Then the final answer was High PSI Walbro and Fuel Pressure Regulator? or the FPR aren't a must?
