Why you *need* to unpgrade the fuel pump, with nitrous/turob/engine swap Options

[97sccelica]

here is a shot of the inside of my engine



#2 piston at 0 compression. more pics on my imagestation site http://www.imagestation.com/album/?id=4291141257

cause, lean fuel mixture as a result of the factory fuel pump failing while under boost.

when the pump wore out, i turned down the boost to 4psi and limited my driving(drove my beater around)

but the damage was done, the #2 piston was sevearly weakened. after i got my new walbro pump i raised the boost back to normal because the car was running fine except for one thing

soot and condensation was blown out the tail pipe upon initial start up after the car was parked for a few hours

so a few weeks ago i was driving hard making WOT runs and for some reason my boost went up to 12psi and thats when my piston gave out.

there is a whole long story that goes with that night but i'll make another post about that.

good news is im getting a new engine from toyota for a whopping $40(they want me to pay for new plugs, cuz the ones i had in there where not recomended and are being blamed for the damage)

turbo ST, driven 6,000 miles at 8-10 psi normally, and 12psi on the last night.

everything else is perfect, and had i not been cheap and gotten a fuel pump and the begining, my car would still be going strong with out any problems.

so if you are doing major upgrades

DONT GET CHEAP AND USE THE STOCK FUEL PUMP

Yea, I remember that venom fuel pump... It's a supposed direct replacement for our stock one. I wonder what it's flow rating is....
