i currently have a 98 gsr, still learning about turbo, etc etc. i've been looking for a blown gsr block for the longest time, and no luck. my question is, if i get a ls block and build it, (sleeves, pistons, rods) would it be just the same if i had gotten a gsr block and built it as well? thanks

Non-VTEC blocks do not have oil squirters. A built LS block can probably handle just as much HP as a built GSR block.

if i did use a ls block, what are some downsides apposed to the gsr block. thanks

oil squirters. that's it.

oi squirters arent even an issue with forged pistons. the main difference your gonna run into is that an ls block has a slightly weaker rod to stroke ratio (1.53:1 in an ls vs. 1.58:1 in a gsr) an ls also lacks a crank girdle which keeps the crank a little more stable at higher rpms compared to regular main caps that an ls uses

parts for an ls tend to be a bit cheaper and more available and u will get almost a half a liter more with an ls block

thanks for the input!

my search for a c1 block continues!

Finding a gsr bare block is very hard. My current build up is a ls block with gsr crank, rod, and pistons. I can get ls block for a $100 all day.

I'd just go with the LS Block. GSR crank would be nice to have though.
