fuel upgrades?

What are a few moderate fuel upgrades (fuel pump/injectors/rails) for my 420a. Im not looking for HUGE numbers, just a good solid HP increase.

What else should be upgraded to go along with these?

well as far as hp you wont really make any by just adding fuel. You'll need other things for flow ratings like headers,exhaust, intake manifold/intake etc.

But a pretty basic upgrade is a fuel pump

I have a CAI and a 2-1/2" catback to a 4" Tanabe.
Any good suggestions then?

First off what are your plans for the car? Unless your planning on putting a turbo on it, nitrous, or doing a bunch of head work, it will be pointless to upgrade the fuel system.

Why not look into a header, high flow cat or test pipe first?

A turbo isnt anywheres in the near future, spray is out of the question (not really a big fan), and head work is a definite possibility.

well Mark (bullettdsm) can speak better for himself, but I believe he was running stock injectors WELL beyond what you're talking about. I think he was into the 170whp range with stockers and only somewhat recently upgraded.

You could tweak a few ponies out of an safc and dyno time, but it would not be worth anywhere near the time or money it will take.

Yup yup. Look into getting cams/ intake manifold/ and a good tune. Ultimately that the best route for n/a

Ok guys, will do.
Any suggestions on a certain product?
Or should I just go the trial and error route?

read up on threads/posts by bullettdsm here and on 2gnt to get an idea of what works/doesn't work
