In my opinion if you own a computer controlled vehicle then tuning software is a must have.

Thanks Thealien for all the info, when I get some more time I'll definately look through it all. |

Re: LS engine swap info
All,
I contacted Novak Adapters and they said they would sell me PN ACG3 minus the compressor for $405.51. (reg $712.00) here is the link http://www.novak-adapt.com/catalog/a...cation_kit.htm I know they specialize in Jeeps, but mostly for LS?GEN III installs in those Jeeps. If you need this this isnt a bad buy, Contact Ryan Information@novak-adapt.com

Re: LS engine swap info
I know they are 10mmX1.5 but not sure on the length. I "think" it was 30 or 40mm.

Re: LS engine swap info
good question.. mine was still in the truck. that how i know.. as for yours.the harness is a little different. I would think if you have the # off the ecm call the dealer and they should be able to tell you.. when in doubt ask.. right

Re: LS engine swap info
I've got a couple of powersteering questions. What thread adapters can be used on the ps box to allow use of the LS hoses? Second, my p/s pump has 3 hoses coming out of it, I know what 2 of them are...any guess on the third? Keep the info coming! I'm about 2 weeks away from jumping knee deep into finishing mine,

Re: LS engine swap info

What I found as an easier solution on the whole power steering issue is remove the fitting off the back of your original power steering pump and put it in the power steering pump you have now (the one with the extra return line). By replacing that fitting you can now use your existing/stock power steering hoses with the new LS pump. Might have to tweak/bend just a little. I'll check out the link although in a couple of the links early in my thread I have links to FAQ threads in a couple of places that discuss the different oil pans and their dimensions.

Good info on the 3rd hose. I don't have the old lines and I have all new lines on the new pump, that's why I was trying to go the other way. I'll price some new "old" lines tomorrow and if not to expensive, I'll just do that. R/

Re: LS engine swap info
Sorry I don't have an answer on how to adapt (which I am sure there is some way). I pulled the engine out of my Jimmy so it was the easiest route to just change that fitting. Do you have access to an old pump? If not you will need the fitting out of a pump and the hoses. At that point it might be just as easy to have a local NAPA or? make up a new line for you.

Re: LS engine swap info
thealien I tried NAPA but if you tell them is for power steering they will not make them, I guess is a liablitly thing... what I did is I got for the high pressure side at the rear of the ls pump used a 16mm o-ring adapter to a #6 AN , they I used 2 ft of braided line, then a #6 an adapter from the braided line to the 18mm o-ring adapter at the gear box, and for the return line, I used the original high pressure hose that is a 16mm o-ring that fits on the return from the gear box, I cut the line, flare it and used rubber hose witha clamp,, and capped the 3rd line.. I think it cost me around 50 bucks including the fittings.. since you need 1-18mm to #6 an adapter, 1-16mm to #6 an adapter and 2 feet of the braided hose... hope this helps a little total cost was around 50 or less,,, cant remember
