Ok, the ignorant girl talking here. So why put a 5.3l in a Yota? Funny how jabs are made about Chevy blocks and here's someone wanting to put one in a Yota 4x4. With that been said, would a lot of changes need to be made to support the larger block and/or the rear gearing?

 

i meant stronger as in power wise. i call the 4.8 a bastard child because a 5.3 has a good amount more power and in most cases get better mileage doing it.

dont think a 4.8 has even made a 12 N/A yet...the 5.3 record is 12.3x NA i think. not that the 4.8 is a "BAD" motor. its a good strong motor that will last forever if you treat it right but i think gm shoulda done away with it years ago and put the 5.3 and 6.0 in everything.

 

There was a guy around here years ago running a small block chevy in a yota and he said it was about a direct replacement type swap. I think he said he had to change the motor mounts and he had e-fans as well not much else from what I recall. Folks are putting these ls motors in everything now, quality, reliability and easy power gains.

 

Just my opinion, I don't think it's worth swapping unless you go to a 6L. Having gone to a 6.0 from a 4.8 myself, I can't see the 4.8 to 5.3 swap as making that huge of a difference.

 

As far as better power, yes in most cases. Better mileage, I dont know about that. I drove four hours, went down the strip 12 times, drove four hours back and averaged 22 mpg with the 4.8. I agree about why they kept the 4.8, the 5.3 should be the base engine with the 6.0 as an upgrade.

 

do they sell the adapters for the 5.3 swap in a toyota or are you going to fab them yourself? because ive got a toyota that needs a motor and im looking for any excuse to get a 6.0 for my truck lol

 

you know this is going into a toyota right?

 

the 6.0 is way too much for an older yota IMO. the power to weight ratio would be nuts. talkn about 70mph burnouts

 

in that light a truck, the 4.8l would be fun. i wanna upgrade mine only because i have a heavy xcsb. between a 4.8l and a 5.3l, the only differences are the rods and crank. everything else is the same. block, heads, cam, pistons, intake. gm did this for an increase in mileage with a minimal expense in parts. worked great. just dont thing its gonna be happy lugging a large truck and/or a load around. lol.

 

I know one that might.......
