Basically your pink wires need 12v..coming from a fused circuit somewhere. I've been getting them to convert over without having to add any extra circuits.

 

Got it figured out. Boy do I feel dumb! Only had to move one wire from C101 to C100... Oh well, now it starts!

 

Glad you got it figured out!!

 

Now I have another small issue. The tach does not work at all. The wire that I pulled from the LS harness to signal the tach under the dash was from C105 G. Apparently not correct. Where should I have taken that from?

 

What was the name of that wire?

 

(+ NW9) Tachometer Signal

 

I don't see why it wouldn't work..

 

I don't know either. Is there another wire you have in mind that I could try?

 

Is it matched up to the proper one on the car side?

 

Almost positive I put it in C230 D which would be the right one, but I'll have to double check I guess.

 

why is the ltx rack not usable? i have a 93 camaro that has a old style small block using the lt rack and old style power steering pump with custom lines. im converting to a 5.3L turbo setup. just curious

 

Because of the angle that the steering shaft comes in at. LT1 is almost straight into the rack, LS1 is at about a 45* angle. If you were to try and use yours it'll hit the pan.

 

In actuality, the racks are very similar. I had both racks laying side by side for comparison. There cant be more than a 10-15 degree difference between the two. I had a bit of trouble with the LS1 rack initially, so I contemplated throwing the lt1 rack back in. If you are running truck manifolds, as I am, you may be able to squeeze them. But I cant guarantee this. The linkage will be very close to your manifold. The main advantage of the LS1 rack comes from the hard/fixed linkage as opposed to the jointed piece.

 

i am running a ls1 shaft that was extended. and will be using foward shorty headers, possibly custom made. but i understand the problem now. i guess i will tackle that when i get to it. thanks for the info guys.

 

I have a picture in my link on the first post of this thread. LS1 Rack & Linkage clears Headers alot better.

 

Now I need to figure out why I am not getting fuel on the passenger side. I pulled all of the plugs and the passenger side looks brand new still. Checking over all of my wires and not finding what I did wrong. Anyone have any help to give there? Been looking at this and diagrams for hours. Now what did I do wrong? lol

Edit: disregard... I am retarded once again

 

anyone regret this swap?

I'm fairly noobish to LS scene but have the urge to swap. Every time something on my LT1 goes wrong I just think "if I had a ls1". I have wanted a 5.3 for years. Am I crazy?

 

No

That's what made me switch

Don't know you well enough to say, lol.

 

Don't hang out with Kenny..

 

Finally about to give up my LT1... Giving me way too many problems and I'm ready to go ls... Is going with a 5.3 worth it or should I wait and try to find a lq for a reasonable price? I know the lq works best with ls3 or 243 heads, but what about the 5.3? Other than intakes, what ls parts are actually interchangeable on the 5.3?
