I had to do a bit of work on mine (LS3 intake w/ truck DBW TB). I had to flip the TB over and then grind the tb servo housing and water pump a bit to get it to fit. Chrenan has the cable TB which will prob fit if the intake runners clear. I still may cut out a bit of the hood bracing to give more clearance on the manifold.

Is there a lower style intake manifold I should be looking for? All the factory style composite car ones look the same to me to be honest. This one *seems* to be the one that other 944 swaps have on top of their engine, but I'm far from an expert.

I don't know what will fit, but here is a good article with pictures.

I need a factory LS1 style intake for certain fitment according to the company that makes the swap kit. I'm guessing I have either an LS1 (confirmed LS1 intake) or LS6 intake, so it should be acceptable for now. Thanks for the article!

Alright, started cleaning up the LS...



First step was to remove the wiring harness. It's basically three pieces, the main harness, the relay harness (fans & fuel pump) and the computer. I tagged everything as I went so I know what connections go to what sensors on the engine, it was a good way to get familiar with things. Since the engine was originally fitted with the throttle body at the back of the block, I'll need a few extension harnesses for some of the sensors on the intake manifold and throttle body. I'll probably need extension harnesses for the O2 sensors as well as I'm planning to go long tube and the bungs are close to the collector for the Texas Performance Concepts headers. There were a couple of wires I couldn't figure out, some back and forth with TurnKeyEngineSupply got it sorted out, they were the check engine light trigger wire and the 12 volt ignition switched wire heading to the coils, O2 sensors and alternator.



Next I removed the exhaust manifolds and pulled the plugs to check them all, nothing looked troubling, and gave the heads a quick clean.





Next I pulled off the valve covers to check the valve trains, everything looked fine, no signs of snapped push rods or broken springs. I have 706 heads, so I checked to be sure the embossed Castech logo wasn't present under the valve cover as well. There was a run of Castech heads that were bad (porous I think), so I didn't want to see the little battery shaped casting pictured below. It was not there, it was a different casting logo, so all is well so far.

Scott at Renegade Hybrids has provided the conversion kits for my 944 and 930. He is a good source for parts and info. Tell him Al from Edmonton sent ya if you talk to him.

I let out a little cry inside....so many projects and not enough time....my poor 944 LS1 has been sitting for too long.

Al

Thanks Al! It's nice that there are a couple of suppliers for these projects, a bit of support is nice.

I'd love to see your 944 LS at Castrol, such a cool car it's been a long time since I've seen it.

Continued with some cleaning and inspecting. Everything seems OK, the oil pickup was a lot cleaner than many engines I've pulled apart. I gave the oil pan a quick clean even though I won't be using it, there is a swap specific version, but I wanted everything clean for storage. I reassembled without the pickup tube as there is a swap specific version of that as well that matches the 944 LS pan.

One interesting thing I noticed is that a rod bold at some point interfered with the windage tray. This was not apparent when turning the engine over by hand. All the rod bolts are ARP apart from those above the damage on the windage tray, those rod bolts are stock. The ARP rod bolts are slightly taller than stock, and I'm guessing they "machined" the tray when initially assembled and started and were then replaced with the stock bolts with lower heads. I took a grinder to the windage tray and gave it a bit more clearance in this area just to be safe. You can see that in the first two pictures, the rest of the pictures are general disassembly, cleaning and investigation.

I gave everything a coating in fogging oil, including the cylinders through the spark plug holes, and sealed everything up. Next I'll clean the intake. I'll remove the LS3 style water pump and sell as I need the F-Body version. Also to sell is the flex plate and headers.

I'm hoping the exchange rate improves so I can order the swap kit, but my economics background tells me nothing is going to shift it soon short of Trump getting elected.

The best way to id the LS1 vs LS2 intake is looking at the floor of the plenum. Looks like you have an LS3 water pump ... That or the truck has the water outlet on the drivers side. This could be an advantage or not depending on the radiator you will be using.
