Ok, I seem to come up with some crazy ideas at work while working on cars for some reason or other. I know this can be done with proper planning. Let's say someone had a ~2000 V-6 F-body M5. I was thinking of everything that would need to be changed to convert the drivetrain to a LS1. Service Manuals are not a problem at all and will probably be put to good use if this ever does happen.
Of coarse there's the engine and transmission, got that part of the swap covered. The subframe is different, so that would be needed, one of the lightweight chromoly would be acceptable also. If it is a M5 car I would think it would be better to go with the M6 over an auto, if it was an Auto car to begin with I would leave it Auto.
The PCM has a different part number. The engine wiring harness is also very different. Not sure about the underdash wiring harness. What about the tachometer? Not too familiar with the PCM wiring going back into the interior, is this a bulk connector, or is it just a few wires run through a grommet? Opinions on keeping everything functional as a new car?
All the engine accessory brackets would be different. The power steering pump could possibly be used with the correct reservior, brackets and hoses. Air conditioning would need compressor, AC hoses. Radiator may possibly work, better to get V8 replacement IMO. Alternator replaced with V8 version.
Now on a factory M5 car, would the clutch master be the same... The V6 line still has the quick connect at the slave cylinder which should be the same. Driveshaft should be the same length. Not completely sure of Torque arm. Rear axle housing same, except with an open carrier.
Of some interest is the V6 cars have a fuel pressure regulator with a fuel return line from the injector rail, possibly use the 97 C5 fuel rail with a higher volumn fuel pump. Air Induction or Exhaust shouldn't be a problem, use factory LS1 parts.
Lets assume everything for the swap was for same year model to make things easy.
I am mainly concerned about how the V8 PCM and engine harness will mate with the chassis wiring under the dash, not looking for exact replies, just thoughts on how this would or wouldn't work. <img src="images/icons/grin.gif" border="0">

Possible benefits are V-6 car looks like V-6 car on the outside, no emblems. V6 car has V6 car insurance. Could the V6 car body be considered a sleeper with a quiet or hidden exhaust?

See I said at the beginning I do ALLOT of thinking at work <img src="images/icons/shocked.gif" border="0"> Did I leave out anything that would be a BIG surprise...

Please no responses on why someone would do this, this is all in Theory and all Technical data is welcome as this is meant to be a Technical Thread <img src="images/icons/smile.gif" border="0">

 

Ah, just get a Formula and have a V8 car that looks like a V6. It would be easier to just remove the emblems <img src="images/icons/smile.gif" border="0">

Lol, now thats an original idea <img src="images/icons/smile.gif" border="0"> Actually the thing that got me started on this is we have a brand new 00 base model V-6 car at SD that they will let go really cheap. I pretty much know I can get $1500 out of the engine/transmission thats in it now. Thats the reason I got started on this conversion idea. <img src="images/icons/smile.gif" border="0">
I may do the first one, I should still have less than $18K with everything and a little extra <img src="images/icons/wink.gif" border="0"> I'll actually skip the "stock LS1" step everyone else has to deal with. <img src="images/icons/grin.gif" border="0">

I wish GM had a uncompleted Z28 chassis like they do with the Z06's, it would make it so easy.

 

Instant message ISERCASTiK on AOL IM (b/c I see you have an AOL s/n in your sig) because he has done the V6-LS1 swap. He said the only way he'd do it again was if he got the V6 car very cheap and/or he had a V8 parts car, and that seems to be what you're talking about.

waddup bro, i did th v-6/ LS1 swap on a 99.....i bought a thet scammed err recovered v6 with no divetrain and a balled up z28 a4..i usedthe cradle/fuel lines/fuel tank,wiring harness dash to deck,rear end assy,brake/gas pedals, the cruise control stuff,rad/condensor/ the cluster, the only thing from the 6 car i used was the body tub literally...i ended up with 10k in the car done...i paid 5 grand for the wrecked car that i needed...i would seriously advise against this swap, it tookme and two guys 3 days to complete it, however my car is perfect and no one can see it was ever a v6 and the SES light isnt lit either..e mail me or IM me if ya wanna...Later,

ROCK ON! Now THAT would be kick ***! I still say that I'm gonna throw an LS1 in a '67 Chevy II or 1st gen Camaro before I die. <img src="images/icons/smile.gif" border="0">

 

Lol, don't think it hasn't crossed my mind. That swap may actually be easier as far as the wiring goes. I'll have to cut up the subframe and change the steering linkage to the front of the subframe instead of the rear to get the engine to even fit. The thing is my '67 Camaro will never be my daily driver, and that really what I need. I actually am planning a LT1 install for the '67 when I am done with the chassis, now that should be real easy to do. I havn't even run the new Vortec 5.7L that I have for it now, I built it 6 months ago.

 

I did a similar swap, I went from an LT1 to an LS1. I am just about finished. The swap itself is not bad IF you had a donor/wrecked car otherwise it will get expensive. Good luck.

 

the fools at the local dealer claim if u use two exactly optioned cars except for he engine that the dash loom will work, i swapped mine to be safe... a 67 nova or chevelle SS would be extremely badass with a
LS1...except those 67 cars are hard to find these days...
