Hello everyone,
I am looking into a ls3 swap in a 3 series bmw and wanting to do a ls3 but most ls3s are around 3-4k with 80k+ miles on them in my area. But I can pick up a l92 that need rebuilt for 300-500 dollars. My question it looks like I could rebuild it and put ls3 vette accessories on it for about the same as a 80k+ miles ls3. What are your options on this and what do I need to know on the conversion?
I'm not looking for any thing crazy 450hp, a nice sounding cam, and reliable for a dd will have a tremec magnum f trans in it.
Do you mind the axtra 100+lbs of weight from the iron block? What are using for an ECU?
wire specialties sells a plug and play harness that is a simi stand alone. I was under impression the l92 is a alum block but yes i would definitely reather have an aluminum block to keep the weight about the same as the straight 6 in it now.
L92 needs the DOD deleted, the compression is slightly lower due to the pistons having valve reliefs, the heads have more flow than stock displacement will ever need, and a cam swap will put you over 500 HP at the crank easily. Buy it, at that price it's a steal.
I've done two L92 to LS3 conversions. Neither had DOD. Both had VVT. Deleted VVT with a TSP kit. Added TSP cam 225I/230E. Better push rods and springs.
I bought used LS3 intakes on the Corvetteforums.com.
One went into a 73 Camaro with a TKO 600. It did 420 on the chassis dyno. Ran great. Super easy to tune.
My current 80 Camaro project has a 2012 L92 converted just like the one in my 73.
I did a LS1 into a 99 3 series. T56 trans. Great swap.

That doesn't sound to bad and is alot cheaper then buying a ls3 but definitely need an aluminum block for weight.
by my understanding a l92 is basically a tq inspired ls3
L92, L94, and L9H (the truck 6.2's) are pretty much the same animal, and that is a 6.2 with a 198/208 or 195/201 (L94), .500/.500 or .500/.492 (L94) cam w/115 LSA.
Otherwise minor differences to the LS3. mainly the 823 head casting w/ same ports & 2cc smaller chamber as the LS3's 821
nothing besides in this car don't need alot of tq lol 300lb car pretty much same wheelbase and length of a 08 vette just a vettes a little wider foot print.

so If i do a 6.2 out of a truck and run a vvt delet and a stage 2 tsp cam the only thing i really need to do is put ls3 valves in it and a ls3 intake and then just all the accessories and should be decent on a swap. I mean I'm at the point ls go for 4-6k in my area with 60k+ miles i can get a l92 that need rebuilt for 500buck that's why I'm considering the l92 over ls3

The only difference in valves is the LS3 intakes are hollow. Not sure that is worth bothering with. Otherwise the heads are the same except for the 2cc chamber increase
