Are all the LS1 sensor compatable with the LQ9 block?
I am going to swap my LS1 to a LQ9 with L92 heads and i wanted to take the sensors off my LS1 and put them on the new engine.
(wasn't sure where to put this thread, move please if necessary)

Thanks in advance.

the only ones i used were the crank and knock sensors. i did not use the others because the part numbers were different.

Where did you get the rest of the sensors?

Yes, they are all the same. The LQ9 will plug-and-play with your engine harness.

are you using the tsp l92 heads or just regular? what cam are you going with? are you keeping the bottom end stock? ive got an lq4 and am thinking of going this route.

I am going to use the TSP L92 heads. The Engine (408) is going to be turbocharged.

I am into the FI, but i am starting to build the engine, and i was confused about the sensors.

Okay, next question, will the L92 sensors hook into the LQ9 block (and work) and plug into the LS1 factory harness(and work)?

Anyone?

I swapped all sensors from my LS1 to my LQ9 w/ LS6 heads. I'm assuming the coolant temp sensor would work as well with the L92s.

Only thing I ran into was the LS1 alternator bracket. Had to drill a whole on the front of the block. There's a write-up somewhere on here.

i didnt do this and have had no problems. some people drill and some ignore.

check the part numbers. i dont know about the l92, but the lq4 and lq9 cam sensor was different from the ls1.

Why are you wanting to use L92 sensors on an LQ4/LQ9 block? All the LS1/LS6/LQ4/LQ9 all use the same cam and crank sensors, the cam sensor goes right behind the intake manifold, while the crank sensor goes in between the block and starter, and the knock sensor go in the lifter valley. Just use everything from the LS1 short block on your 408 LQ9 short block. The L92 has the cam sensor on the front by the timing chain cover, and the knock sensor are on the side of the block (one on the driver side and the other on the passenger side, both by the exhaust manifolds).

If your car is high miles. I don't recommend re-using sensors. They are cheap relative to the pain in the *** of having to dig them out again when they go bad. If your spending money on a new block and all that, spend a few dollars more and put in fresh sensors everywhere you can...

Bumping a super old post, but this is great info. Thanks guys. Swapping an LQ9 into my Third Gen and this helps me know what I'm looking to get for sensors.
