ok so i'm starting to gather all the necessary parts and i'm looking at picking up a used complete pull out lq9 and going with the 6l40e / ls6 intake

i'm putting all this in my 91 firebird and tossing the 3.1 so to make things easier i'm ordering a spohn k-member & torque arm i'm not looking for an all out monster or anything crazy just a very strong very reliable fun street car for weekend use

with that said wiring i know is going to be my biggest problem

if the pulled engine comes with the wiring harness sensors and all the accessories how much is any of that can i really use? what should i replace? and when ordering am i going off the lq9 parts or ls???? Does anyone offer an aftermarket wiring kit for this setup yet so it'll just be plug and play sort of deal thing LOL

i know i need to relocate the alternator to fit under the hood as well as get an fbody oil pan new rad & fans and i'm also looking into upgrading all the gauges in the dash

i'm just trying to gather everything needed now and make this all as easy as possible as yes i have been on here reading everything i can find on this swap and i'm sorry but most of it is all about my head but i am trying to learn so that has to count for something lol

thanks for the input and feedback
i'm heading back up to reread the main stickies yet again

 

For Wiring:

Read this, https://www.thirdgen.org/forums/ltx-...ml#post4305264

-or-

If he is still modifying harnesses (as i dont want to speak for him if he isnt) talk to Pocket and have him make you a plug n play harness.

Keep reading the stickies, they cover it all.

 

You will need the car intake, accessories, oil pan rather than the truck stuff. I am sure you have read this, but this is your friend:https://www.thirdgen.org/forums/ltx-...third-gen.html. There are plenty of experienced swappers on here, so I am sure they will chime in. I am not one of them yet, but have done lots of studying.

Also, I would see user "Pocket" for a modified wiring harness rather than by an off the shelf one.

keep searching, and good luck!

 

?!?!?!?!

 

LOL...When I started my reply, no one had posted. Guess I got side tracked and by the time I hit enter you posted. Beat me to it. LOL

 

ok so for the intake and accessories i can just call summit and order everything for lets say a 99 ls1 ta and it'll all work with out any problems

I pm'd pocket two week ago and just sent him an email so with luck i'll hear back from him before i'm ready to get started on this

 

I would just search for used accessories and brackets if it were me. This is the main reason why I ended up buying a LS1 dropout, because all the little things add up fast. You might be able to find some of the stuff in the classifieds here, but I would search over on http://ls1tech.com/forums/marketplace/parts/search/ for a used accessory setup. I can check a couple of people I know to see what they have if you want, let me know. I would also try to pick up a used LS6 intake to put on. But definitely check out ls1tech's classified section.

 

coptzer that would be great if you could please let me know what you find

I've just joined ls1thech and a few other places over the past few weeks and i'm still looking around for parts and reading reading reading

Thanks Again

 

That's the key. I didn't know anything about LSX engines 9 months ago, and in that time I managed to swap and get mine going with pretty much no confusion or issues. I had an insatiable appetite for LSX knowledge!!! Still do, in fact.

 

^^^^This sounds just like me when I started researching my swap. Lots of great info on here. Start reading through other people's build threads and you will learn a lot about what you need, what works and doesn't, along with some great tips. I'm starting the wiring next week, which is the part that worries me the worst since I have the least experience doing this. Good Luck

 

I also bought a ton of parts on tech. It was my daily ritual to check the classified section on my lunch break and continuously throughout the evening. Deals pop up and are scoffed up quickly.

 

I assume you meant 4L60E (or else I'm really confused...).

You might try to find an f-body LS1/4L60E dropout with a bad engine. Swap over the f-body stuff & transmission to the LQ9 longblock, go from there. If you get the LS1 harness & PCM, you'll have the cooling fan controls as well.

If the dropout is 2001 or 2002, you'll get the LS6 intake.

Of course, all of the other LS swap details in the sticky also apply. If you read the sticky carefully, you'd see there is a link in it about what you need to do when starting with a truck engine.

I also wouldn't hold out for an LQ9. An LQ4 is still a huge step up from a 3.1 (as is an LS1).

 

Yeah I will check a couple people for you. My brother has a couple lsx motors kicking around his garage, but not sure if he has fbody accessories. And like everyone is saying, read through others builds. This forum is officially your new best friend. I have my motor in my garage now, and I am still trying to figure everything out.

OMG! It seems like things are only on there for minutes before they get sold, at least the good deals.

 

Well first off Ill say welcome to the lsx side of thirdgen.org..you will be here a long while lol.I started out not knowing a single thing about ls motors untill I bought mine and read the stickies.With the wiring..Pockets posts are like the bible.Dont worry about the wiring as it was wayy easier than it looks.The engine harness is almost complete stand alone and if you want to save alot of time and not rebuild the entire thing..I plugged in all the sensors on the motor and anything else I didnt need I simply cut the connector and tucked the remained wires back into the wire loom.

Take your time to understand what you read on here..look at the well documented pics and you will be just fine.Parts wise for the swap..go to the Hawks website and look at their lsx conversion section to give you an idea of what is needed specifically for our cars to get the motor/trans installed.The fbody belt drive system is the most common to use for the least amount of hassle and you can reuse your original radiator and fans,most guys either use stock fbody manifolds and then custom y pipe and catback exhaust,fuel wise the corvette filter/regulator is also a popular choice for ease of installation with a few fittings.All your gauges can work normally..no need to go fully aftermarket unless you want to.

On a budget I did my swap in a full week from my 383hsr/700r4 to ls1/t56 and I learned everything from here.I asked a billion questions and found my answers easily.The smile on that first ride on lsx power is priceless.Now I want more lol....

 

Some good deals on there daily. I got a set of 205 afrs for 1000$ shipped.
I sold my 500rwhp n/a motor within 2 hours of postin.
I sell/buy lot of stuff on there too..

 

Lol funny you say that.My two main pages on google chrome are thirdgen.org,ls1tech,and then youtube :P

I usually have thirdgen and the tech classifieds up all the time.I got a ls6 intake on tech for $200...it was posted and sold in 15 mins at 3am.You gotta be a shark on there for true deals and cash/paypal ready!many parts I needed during my swap was found scavenging through there.You can also get lost reading endless info on building some nasty motors on a budget.

 

Getting lost is an understatement lol I just spent another 3hrs reading my wife just woke me up to come to bed lol

 

I know the feeling dude. My wife tells me all the time I am spending too much time on here. Oh well!

I checked with my brother and another guy I know, and no luck with the fbody accessories. I think my brother is going to be selling a LS1/4L60e though soon. Not sure what is coming on it.

I got your PM, and I will check into it for you.

Steve

 

If you go carb, you only need a few wires. Starter, distributor , oil pressure, thermostat and probably 2 or 3 more.

 

true but going carb requires a $250 (minimum) intake, an LS1 intake complete can be had used for $150, if your going to go through all the trouble of an LSx swap, new age technology, why not use the tech in front of you?

 

 

yeah no carbs for me!!!!

 

I think my brother is going to be selling a LS1/4L60e though soon. Not sure what is coming on it.


pm me the details on your brother setup and time frame
as of now nothing is set in stone

thanks again

 

Yeah I will ask him in more detail this weekend and let you know. If for some reason you don't hear from me, send me a PM. Keep in mind that it will most likely not have wiring, accessories, and not sure on oil pan. So you might still be better off with a complete pullout from a salvaged car. Probably will have the stock LS1 intake, and 241 heads. This was pulled to build a 383 motor in its place I believe.
