Sanity Check 14b injector size

[gorf]

OK I have done the maintenance, and stage one mods.
I have a ported 14b and have purchased some four hole evo 560 injectors. I plan on purchaing a stage three chip from dsmchips with the fuel map for 93 octane and the 560's. I also have rewired a new 190 Walbro.

I know 20 lbs is REALLY pushing it for a 14b, especially with no fmic.

According to RRE site all I really need for 18 lbs on a 14b is a fuel pump.

Am I going over-kill on the injectors? Will they actually buy me much with the 14b?

Your not going over kill on the injectors but 20lbs is pushing it...i would stay at 17-18lbs without a front mount.

I have a evoIII and am pushing 21 pounds. no fuel cut or anything, and only getting around 2 counts of know..

stock injectors.

21lbs and stock injectors? Any idea of how much HP you are pushing?

With my 14b and 18lbs I was hitting fuel cut, I checked for boost leak and I think I found one and fixed it, but I need to re-check it after running for a while.

Seems fishy to me, 21 PSI on an evo 3 on stock injectors with 2 counts of knock. Any other fuel mods? I am running 20PSI on my hogged out 14b with 550's, 2gmas, AFPR, Walbro 255, 3 fouled plugs, FMIC etc and it runs great!(beside the plugs) I'm just waiting on my NGK BPR8ES to get here i ordered from AMS. This spring im going to hit the dyno before i upgrade just about everything.
