Wich walbro 255 need to buy?
 

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?

$4 more for a Walbro from TT...

Xenocron runs a great business with quality products, but i think ill go with a name brand on this one.

i would also like to know why to use the HP one over the LP? is the LP not going to support the same hp levels? isnt the LP the same fuel pressure as stock, eliminating the need for an aftermarket fpr?

Really don't know.

We have a 94 SI Coupe with a B16a with an Walbro 255 with B&M FRP and everything hold solid @ 42psi at idle. Never have we had a flucuation or some crazy psi spike.

I'm the same thing in my 93 Hatch with a built ZC. The only Difference is my FRP is 20.00 Aerospeed Ebay FRP. Looks and feels 100% the same as we installed both unit side by side in the shop at the same time.
