Fuel pump upgrade

[dkrupp79]

I have a stock bottom end 1991 with the following,

Ported Windsor Jr heads
B303 cam
GT40 upper and lower intakes
24 lb injectors
BBK 75mm throttle body, mass air sensor and cold air intake
BBK shorty headers, X pipe and Flowmasters

My question is, should I upgrade my fuel pump?

I plan on putting a 100 shot of nitrous and getting it tuned by a local speed shop.

Well if it is the stock pump then it is 34 years old and you want to risk your motor on that with a nitrous setup? Do yourself a favor and put a Walbro 255 lph pump in it.

Thanks, should I replace the ecu with a Megasquirt, since it's 34 years old as well?

There's a pretty good chance that you will run out of fuel with a significant hit.

Not necessarily. I would, however, send it in to https://www.theecuexchange.com/ for a comprehensive check and refit.

Get a 255 lph and call it a day.
