Fuel System Question
First question is....What is the complexity of installing a aftermarket fuel pump such as a walbro 255...im pretty handy i do mostly all my work....any writeups?
Second question...I know someone that owns a engine core supply company. basicly he buys blown or cutout engines by the truck load, strips them down to the core and sells them to rebuilders. In most cases all the accessorys that are on the motors ie. turbos, injectors, etc are just separated. He has tons of injectors, 5 gallon buckets full, my question is is there a way to identify the flow rate of these things just by looking at them? im sure he would give me a set super cheap and from there i could send them out to be cleaned and rebuilt....

Walbro is easy to install the only diffrents between that and the supra pump is you have to cut and splice the wires. I would go for the supra pump any ways much more reliable.
Next is there are vary few cars out there that have side feed injectors like the FD does. Also if you want bigger injectors you will need to bore the stock ones or add 850s to the primarys or you will need diffrent fuel rails to add top feed injectors. Any way you will have to have a non stock ecu to do an injector swap.

The only way to be sure is to run them on an injector dyno and test for flow rate.
You need at least to check the injector coil impedence too.
We can do this service.

Can you run an aftermarket pump like the TT supra pump with the stock ecu??

I understand, i was asking cause i am having an issue with my car. I wanted to rule out the ecu part, thats why i asked. Thanks.

You guys have a link to a write up somewhere? I remember seeing a very nice detailed one but I've been searching and cannot seem to find it. The one for the Walbro pump?
Thx
