Short Blocks
If your current short block has been damaged beyond repair, like that time when you turned your boost controller up to 4+PSI and tossed a rod through the side, then it is not the end of the world. RallySport Direct can get you back on the road with a fresh new short block. These are perfect for those of you who also need to replace a tired motor, or even if you want to swap an STI short block into that WRX. We have bare blocks, stock short blocks, and we even carry built short blocks, the factory short blocks will come from Subaru OEM.
And if you want to keep your factory short block and build it into a monster, that's okay with us too. Just make sure you check out our great selection of pistons and sleeves, heads, and turbochargers.
