Don't tell my mom, but if I was ever to stray from the General it would be for an M3.

Nice work so far. What are you painting the underside of the chassis with?

Chassis Saver - Similar to POR15 but in satin.

It seems with any swap there is lots and lots of research. Actually one part that I really like. The LS3 AC compressor has the line exit direct into the frame rail so that wasn't going to work. I happen to have a truck bracket and come to find the LS3 has the same belt spacing as the trucks....

Tried a couple different truck compressors, no go... lines again exit directly into the frame rail.

Thought about using the stock s50 compressor and make a bracket. It would be nice to use the stock lines. It does "fit" but sits about 2" further back than stock so the lines really wouldn't work anyway.

A couple pictures of how it fits.



Belt lined up




I really wasn't too happy with that so started digging. I use google images a lot to find things...seems to work the best for me and is the fastest.

I found a bracket to use a sanden compressor on the LSx.....like this. I THINK the lines will clear the frame rail from all my measurements. If not there are different sanden compressors with the lines that come out the back.



Some more digging and I found that the trailblazer/enovy has a different AC compressor than the other trucks with the LSx engine.
The compressor has the outputs more on the TOP..... looking like this might work.
I have a compressor coming tomorrow to see if that will fit. Looks like the bracket can be bought new from GM for around $25.
A few pictures of that setup...these are not mine.

Picked up a trailblazer compressor...

It fits great. I'm not sure if I will keep this exact compressor as it is painted black. New rebuilt from the parts store but just looks out of place not matching the engine. Gotta see what else I can find. But this type works for sure with the LS3 belt spacing or truck for that matter.

Line location


Clearance to rail


From the front...uses a truck tensioner


Here is the bracket.
LS3, truck, trailblazer. I will have to drill a hole or weld an ear to the back for the lower hole as the LS3 mounting is a little different. Top bolts are the same and everything lines up tho. There is even a cut out on the back of the trailblazer bracket where a hold could be.

I was hoping to make the trans mount and start on headers today but I come to find that there is no rubber mount on the tr6060. drat! I have a rubber mount on the way.

Either way...lots of other things to work on.

Brake and fuel lines....powder coated...calipers will be coated to match




Clean tank ready to go back in


Straps with new pads


Tank is back in


Just some random pictures now that it is raised up.

New bushings in the rear subframe just about ready to go in


Coilovers


Front of the diff reinforcement


Got the rubber trans mount so the plan was to make the trans mount. Looking like I need to figure out the shifter situation before that can happen tho. This is a tr6060 so the shifter uses a linkage unlike on the t56. Trans has to be a little lower to give room for the linkage...



Thinking of using the camaro shifter holder and modifying it a bit.

BMW compared to the camaro shifter


The shaft diameter is just about the same so I am thinking a BMW **** will fit.


Camaro shifter pulled apart


What I am thinking is cut the arms that go to the trans off (where the ratchet is in the pic below). Then mount the camaro rear carrier to the bottom of the e36. Then weld the mounting location from the front (cut off) back a bit further to mount to the trans. Finally shortened the shifter linkage.



By lowering the back of the trans the space between the brake booster and valve cover it REALLLLLY tight. I will probally change the engine mounts so it sits a little lower and gives more clearance at the brake booster. I have about 3/4" between the pan and the subframe right now so there is some room to go a bit lower.

A little more progress on a shifter option. I am looking at a couple different options but right now I am planning on making a new carrier that would mount directly to the trans. It would use the camaro shifter or an aftermarket short shifter.

Drew up a test in Alibre (3d Cad) and printed out a test in ABS Plastic.

On the printer.


You can see there is a little ledge down in there.




The camaro shifter uses a plastic bushing similar to how BMW does.

It uses a little locking plate to hold it in.


Up in the car...


The idea right now is to make the piece I made out of plastic out of metal. Then make some supports from the carrier ring down to the mounts on the trans.
Then also make a new selector rod that will go between the shifter and trans.

Hold da phone!Did you print that out on a 3D printer?Is that the final product or mach up for a future machined piece?Very cool and interesting.I always wanted a 3D printer but the cost makes them impractical for me.

Yup...that's printed on a 3d printer from ABS plastic. Pretty awesome stuff!
No that is not the finished piece. I will have something made from steel on a CNC lathe and then weld supports to it that will connect to the trans.

Nice work

thanks! It is a nice little touch

Then made out of metal.... The stock camaro carrier has the shifter coming from the bottom up. This design has it from the top down. That way if the shifter ever needed to be replaced it would be MUCH easier. It also will make getting the entire assembly in and out of the car a lot easier.



There will be a plate thin plate on the top to hole it all together.


You can just see the small lip down in there


The circle might get squared off on two of the sides to make welding a bracket to go to the trans easier.

Wheels showed up today! Tires will be 265/30/18 in the front and a 285/30/18 in the rear. To fit a tire that wide it with get e46 fender flares grafted in.

Just pics of one of the rears and specs on front and back.






Will run a 15mm spacer in the front.

What brand wheels are those?

EDIT - found their website. Do they only make 5 x 120 wheels? Looking for some good/cheap/light track wheels for the Panoz, but it uses Mustang bolt spacing.

BMW is 5x120... So yes these would work if the offsets work. They are light wheels

New rear suspension going in.
not a very good picture...




New grease in the axles




Two fresh axles ready to go in


Engine is coming back out tomorrow to make the new shifter carrier. I will probably also hang the rear trailing arms too.

Check out the V1 CTS-V shifter. It is the same style as the camaro, but it's steel so it would be much easier to modify.
