Recommend me an injector size and plugs

**PacerSS** · 07-31-2010

As the topic states, I need a suggestion. I am top swapping when I get back and have a pretty extensive mod list to add on. Since I am noobly when it comes to the boosted side of the world. I need an injector size since I am pretty sure that stock L67's aren't going to cut it. Also need a spark plug suggestion since I don't know what would be good on a boosted motor too. Mod list will be as follows:

Gen V
N*
LQ4 MAF
Speedbuilt FWI
ZZP Stage 4 Heads
Intense Stage 3 Blower Cam(.539/.562 int/exh with 116LSA)
Meziere Water Pump
ZZP headers
Full exhaust with catless DP
180 drilled T-stat

42.5#'s would probably do it for you on 93 octane. If you want to switch to race gas or anything, I would just go with 65# that way you have a lil room to work with.

Your probably going to run AL 103's gapped at .04 or lower depending on how much boost you are going to run.

Appreciate it fellas. I don't know how much boost I will be running but I plan on starting off with a 3.4. I think I can get away with that and have it not be a knock monster. I was thinking 3.5 to be safe though. I don't plan on running race gas or E85 as of right now so I think I'll go with the 42.5s thanks again for the advice.

I would think you would be able to run a smaller pulley than that with those heads and that cam.

Never know though.

I figured as much too but with no IC yet and the ***** it's going to be to tune starting off, I thought I'd err on the side of caution before I got too extreme with it. I've got a 2.8, 3.0, 3.2, and 3.4 so I figured I'd start at the top and work my down before it started crying. lol
