Any differences in the bottom end between L32 s/c and n/a? Need another bottom end so im trying to buy a used engine for my build.
 


Well yeah.

Because the Supercharged 3800 in '04+ cars is the L32
The N/A 3800 in '04+ cars is the L26...differences?

Compression ratio is higher in the N/A car (8.5:1 vs. 9.4:1) and the rods in the L26's are tiny compared to the L36/32/67 engines.
 
04 L32 is only an L32 on top, bottom is still L67
05+ is all the same except pistons on L32 are forged and L26 are not and the difference in compression.

Click to expand...

L26 = 9.4:1 Compression
L32 = 8.5:1 Compression

L26 rods are smaller than L32 rods...so sit a set next to each other. Oil pan is different...L26 heads and L32 heads flow better and have slightly larger valves as well.
