Stock S50 vs OBD-1 converted S52

[jpmarotta]

Firstly, yes I've done a search.

Wondering if anyone has put a stock S50B30 head to head against a S52B32 converted to OBD-1?

Trying to figure out how much "extra" power the conversion give you and whether or not it's worth the additional cost.

i'll see if i can post up my buddys dyno we have similar setups except i have an s50 he had an s52... dynoed one after the other on the same day. they were within 5whp from each other

might as well try and get as much displacement as possible from the start. the cost difference is negligible, s52s are all newer so think about it that way.

It would depend on the specimen.
You may get , by chance an above average S50US, or a Below average S52US, so you never know unless you dyno or the thing simply flies at the track compared to similar cars.
