Here's the scoop: I'm doing a VVT block, 4W head, boring 1mm over to fit 10.5:1 Wisecos and a FM turbo kit. Crazy, a little, but could be fun. Should I delete the piston oil squirters or leave them in? I've heard differing opinions and want to see what the turbo hivemind thinks. Thank you in advance!

 

Leave them in. I always have and have never had issues. I'd rather have their benefits.

 

Makes sense. I ordered the plug kit from MiataRoadster but I can re-sell it. Thank you for the input!

 

On a turbo build it's no question for me. The piston lubrication and more importantly cooling is great. There's a reason they developed them for rally turbo engines back in the day. Potential downside is more oil getting past the rings and burning, but it should mostly be a non issue and the benefits are worth it.

On an NA engine it could be different since heat on the pistons and detonation is less of an issue. And less oil clinging to the pistons is less rotating mass and all that. Lots of people swear by deleting them but I'm with Curly on this one.

 

2 in favor, 1 opposed and I don't even talk to them anymore. No-brainer at this point.

On a side note, does anyone want an oil squirter delete kit?
