lq4 with ls1 intake
not having much luck finding the answer i'm looking for. I need the ls1 intake on the lq4 swap I've started buying parts for. From what I've read:
lq4 injectors wont fit in the ls1 intake.
ls1 injectors wont plug into the lq4 harness.
lq4 fuel rail wont fit ls1 intake.
Tell me if all of these are true or false. Now the fuel rail thing isnt such a big deal to me, but the other two are. Correct me if I'm wrong but if I run the ls1 injectors the lq4 computer will have to be retuned (lq4 has bigger injectors right?). Do I have to run a ls1 harness and/or pcm to make it work? Is there a way to use the lq4 injectors in the ls1 manifold? Is there a way to hook the ls1 injectors into the lq4 wire harness? whats reccommended? thanks.

I cannot answer your question, but...
If you are running the truck acc. drive then the LS1 manifold will conflict that way also.
If you are selling the truck acc drive (P/S pump, ALT, Tensioner, bracketry) let me know...
I'm in the market.

What you have doesnt sound wrong. So you would have an LS intake/ LS style injectors and an Ls harness ( or atleast a moded harness for the injectors ) - but you'll have an Lq longblock. What type of car is this going in. You dont have to use any specific PCM, but which one you use might have to be tuned accordingly. ( unless you got LS aftermarket injectors of similar output to the LQ - if u are using the lq pcm. ) - I would have to double check my service manuals to see what would and wouldnt fit, and what size everything is. I'll try to do that at the end of the day and get back on here.
I wouldnt say anything is recommended though. - When you do mix and match you have to more decide what you need. -

As has been mentioned, go to the performance truck site and search. A lot of new info since I did my swap.

I know of a number of people and at least one write up of an ls6 intake swap on this motor. It seems like that might be the easier approach and from what i have heard yield better performance.
I have not done it so take this with a big grain of salt.
The write up on the swap is on ls1truck.com

its a 3rd gen camaro swap, I was planning on getting an fbody accessory drive and using that, is it cheaper to do the set up in the link you sent?
How did you end up getting the TV cable to work?
I'm just starting to aquire parts, so nothings for sale yet.

Is there somewhere I can find more info about adapting the truck accessories to clear the LS1 intake? How about a place where the brackets/conversion parts are available? I didn't see anything on Speartech's website or by searching.
