Carbureted LSX forum - Semi built lq4..carb or F.I is the question!
07-10-2012, 08:33 PM
I have a semi built lq4 just pulled from my truck..motor consist of 0.30 bore with 10.5:1 hypereutectic,PRC 2.5 heads with a comp 235/243@112 cam..truck manifold,stock TB with 44lb injectors..swapping it into my 89 gt fox,not sure if I'm going with turbo 400 or t56 yet..just wanting to get some opinions on leaving it how it is with a swap harness..or buying the edelbrock Vic jr mani,with control module?!
Is the Vic jr or performer rpm better for my setup?
If going with carb..what would be a good size/brand carb?
Will it clear a 2.5in cowl hood?
What would be a good stall for the setup,if going with an auto?
this will be a street/strip,weekend warrior car..
Any advise will be appreciated!!

If you go carb'd you're going to really open up the top RPM compared to that truck intake.

Easier to swap. cost less, makes gobs of power without buying a big aftermarket EFI intake, should clear the hood, looks better to most of us, if it is a weekend warrior, or a street strip, occasional use, carb is the way usually.
More initial cost, slightly better cold starts IF tuned right, slightly better economy usually, but not enough to talk about, requires more fuel and need to be able to make a harness work and ECM, looks cool to many, if a daily grinder, it is a preferred setup, more wires to take away from some of the look, you need so spend money on dyno tunes ect.
That is my personal input.

Is the Vic jr better then the performer rpm for my cam size?...also what would be a good size carb for it,decent brands out there?

If you are looking for max power and not cruise it everywhere, the Vic Jr, the performer is better on engine that live below 6000 for sure.
I run a holley 750 that i built, works great. Most street 6.s here run a 750 i think.
