It depends which car the engine is coming from. Blacktops will always be newer. ---

If you’re planning on selling all these engines, shouldn’t you have done abit of research about them first? ---

The only difference between the two is the year they were made and I have no proof of this but the Redtop Pistons have Slotted Oil Leads in their Pistons and the Blacktop’s have Circular Oil Leads in their Pistons. Thus meaning the Blacktop Pistons can take more boost. But not much more like 5 more psi… ---

[quote=“SHIFT\_SR20DET”]The only difference between the two is the year they were made and [quote] Well… on S13s yeah, the blacktop from an S13 is the same as the redtop, the S14 blacktop is different tha the S13 and the S15’s blacktop is different than S14 or S13 blacktop, and not just the turbos moving to T28s… ---

If you can get an S13 Redtop and an S13 Blacktop for the exact same price, then obviously go for the blacktop. Newer engines = teh win.
