Well I just got a Zex wet kit for my car and I plan on installing it this weekend. I have a few questions first.

My setup:
11.3:1 CR B18C1
Forged pistons and rods
stock injectors @ fuel pump
tuned by me on crome

1) Zex recommends that I upgrade my fuel pump. Should I do this and if so, with which one? Walbro 255, 190?


2) Zex also recommends retarding timing 4* at the dizzy. Can I leavew the dizzy and just pull 4* timing from 4000 RPM and on in CROME?


3) Finally, I hear a lot of people say go 1 range colder in spark plugs. I already went one range colder over stock when I put in my B18C1 engine, should I go yet another range colder (2 colder over stock)?


Thanks for your time and help!!

just get a 255, it'll be good for future upgrades also. run ngk 7's. and yes, you can just pull 4 degs above 4k, as long ans you dont apray under 4, have fun, and i recommend to atleast run mixed gas, if not race gas

i say run higher than a 75 shot although 100 is probably all you can do on pump gas.

Get the 255 pump and the ngk 7s and have fun lol

i wouldnt run a 100 shot on 11.3:1 compression on pump gas

if its a wet shot, it wont be bad. just make sure detonation is NOT happening.
