I have a 97 Dx hatch with a B16a2 swap. I just bought a Zex kit & Purge. Will my Stock DX pump hold up to the 75 shot I plan on using or should I upgrade to a Walbro 190 pump? I also have a set of OBD2 GSR Injectors. Should I use these injectors instead of my B16 injectors.

 

I would definently upgrade that pump. The stock dx (at least in the eg) pushes about 72lph.

 

Do you think a Stock Si fuel pump will work? I have out of my 00 si that is totalled.

 

The Si pump will be better than the stock DX one, however a Walbro would be better, at least you would need to worry about not having enough fuel pressure. As for the injectors, all B-series are the same.

 

thanks for the info.

 

If you are going to run a 55 shot then the Si pump would be sufficient enough. If you already have the pump then drop it in, if not I would go with a Walbro as the other's have suggested.
