Engine opinions

[dleroy]

Okay so since I've had my 2000 SLE I have been wanting to supercharge it but finding a donor engine, transmission and other things has been a struggle so I was wondering what the best plan is or your guys opinions. What engines can even be swapped into these cars and would it be better to try to find a stock supercharged engine and build upon that? I may be asking stupid questions but I'm new and not trying to make an ass of myself.

L67 swap gets my vote, ~$600 for the motor, $200 for all new gaskets, 2 hours to pull the old motor and 2 more to drop the new one in. Your trans is fine unless you're running slicks/drag radials at the track, in which case an hd trans wouldn't hold up any better. If you really wanted to, you can get the hd upgrade from zzp and just swap the diff/cover, passenger side axle, and output shaft. Minimal pcm changes, just need to have the L67 engine parameters loaded up.

Top swap is another option, bit more involved, and you'll need mods to be able to run the stock pulley. Plenty of info on this on gpf if you wanted to look it up.

You could also sell your L36 to make up some of the cost on the L67 swap, or keep it as a back up if you go that route.

To do the engine swap you need the adapter harness for the MAP sensor as well. Then a tune.

Or the L32 map sensor, it has the same connector as the L36. Also no need to worry about the bbv wiring, just vent it to atmosphere. All this will do is prevent the pcm from cutting boost for tq management.

Topswap can be a good option. You get to replace a lot of gaskets, maybe do some porting, and you gain a little bit of performance because of the higher compression.
