Upgrading To A 125 n2o Shot

I've been out of the car game for awhile now. I'm coming back from Iraq in two weeks and I want to upgrade my dry Zex 75hp shot to a 125hp shot. I don't really remember everything that I need. I believe I need a new fuel pump, fuel pressure regulator, and a tune. Is there anything else and can I get specifics? What kind of fuel pump and fuel pressure regulator do I need?

Congrats on coming back from Iraq!! Preciate the work you've done over there.

Now on to the N20:

I when I was at 100 shot, I used a Walbro 255lph pump with a Aeromotive FPR, those are the best IMO. BBK makes a cheaper version of the FPR as well.

Be careful when using the 125 shot, because its putting alot more stain on the internals than the old 75 shot. Just use it sparingly IMO.

You definetly need a new tune, preferably on the dyno...

hope this helps...

Mountain cat or whatever his name is, has been running a dry 125 shot for awhile.
So I would say you would be good. Just upgrade your fuel pump, get a regulator, and drop timing a little more.
