Everything needed for an LQ9 swap
Everything needed for an LQ9 swap My LS1 spun a bearing and now I am looking to get an LQ9. I've done multiple searches on here as well as google and this is what I came up with:
-Alternator bolt hole in block needs tapped
-Truck intake will not fit under cowl
-Something about the windage tray needs to be cut to fit F-body oil pan
So, my questions are:
-Do I need the windage tray or can it be taken out? I read on another site somewhere that you don't need them but I have no clue on the matter.
-I have an LS6 intake that will be put on - If I am still going with the LS1 PCV system, do I still have to smooth out the certain points on the bottom of the LS6 intake?
-How much does a COMPLETE LQ9 engine weigh? (oil pan to intake) I have searched everywhere for this and couldn't find the answer.
-Is there anything else I'm missing?
The engine is an '05 BTW
Thanks everyone!

you can use the f body windage tray and pan.i would keep the tray as it's there to keep oil off the crank and stop it from being whipped up by the crank. the alt bolt needs tapped if you want it but lots of guys run without it with no issues. as far as weight i have no idea but it is supposed to be 80# heavier than an aluminum motor

Hell no a truck intake wont fit. You"ll see. Unless you want to cut your wiper blade part of your cowl.
Take the Pickup tube, windage tray, and oil pan off of one LS engine, and put it on the other. Oil pan, windage tray, and oilpan are all oil pan spacific.
You need one with the other.
Thanks for the info guys!
Anyone have any information about chiseling off the ridges on the LS6 intake? Do I still need to do it with the LQ9?
Now I just have to find out what the weight will be to estimate for shipping. Does between 650-750 lbs sound about right? (This is for the entire motor)

Being less than I estimated is definately a plus then!
I'm guess I'll just check to see where the coolant lines are on the LQ9 then and chisel off what needs to be taken off, depending on where the lines are run. Either that, or just chisel everything off. I don't see how that would hurt anything...
I just read something else about the oil pressure sending unit - says that the LQ9 comes with a 3 wire and I need a 1 wire. https://ls1tech.com/forums/generatio...p-what-do.html
I'm thinking about putting the MS3 cam in it as well since the engine will already be out. I will be mainly doing pulls from some sort of a roll since I still have the 10 bolt and also a lot of highway cruising in the summer. This seems to be the best cam for what I want from everything I've read but I'm open to suggestions. I will not be swapping heads at this time (317's are on it). I'm hoping to break 400/400, not that numbers mean anything. Also, this car will probably NEVER see the track, if anything it will be autocrossed but I don't even think I'll be doing that.
Let me know what you all think...

You don't need to chisel off the bottom of the intake for knock sensors. That's only if you want to run the LS1 coolant crossover line, that goes under the intake. You can do that, or just buy an LS6 coolant crossover kit with the rear block-offs, and not worry about it. If you want to make good power, and not break the bank, look into a set of L92 heads. I was able to pick up a brand new set for $650 shipped. With the right cam, you'll make high 400's at the wheels. But, you'd have to run an LS3/L76 intake, instead of the LS6.

Another thing to look into is make sure that 2005 Engine has the 24X Crank Reluctor..I don't remember what the last year for that was..I think it was 2005 though.
Sorry for kinda stealing the topic away, but I am interested in the same thing, and if I were to get a shortblock, could I take all my accessories off my LS1 (waterpump, starter, sensors, etc.) and just swap it over? It seems like the only difference is the alternator bolt and the top end. Can I get away with a running motor with just the LS3 intake and heads with my TB? Trying to figure all the business out ahead of time and spend money once.

So, anyone have any input on the MS3 cam I'd like to put in? Doing a cam swap is all I have in the budget right now. As much as I'd like to swap the L92 heads over, it just isn't in the cards right now.
