Forged Piston to wall clearance

Postby Justacorolla » Wed May 20, 2015 6:05 pm

Hey guys, I recently purchased a set of forged toda high compression pistons for my 20 valve (part # 13040-101-000). I have attempted to get in contact with Toda in regards to a recomended piston to wall clearance but have not heard back. Does anyone have a better way to get in touch with Toda or does anyone know the specs for these particular pistons? Thanks.

did you contact Toda Japan, or Toda USA??

I've sent emails to Toda Japan a dozen times... I have yet to get a response - they have crappy customer service. Toda USA, Misano Motorsports did answer a few questions for me..........

I am having Arias pistons installed in my block as we speak! The sheet from Arias says 0.004". The machinist doing my block says 0.002 - 0.004" is normal, 0.006" max.
Let us know if you get info from Toda.

I have cp pistons on mine and they have similar specs, most people do .003 to .0035.

The last set of Toda pistons that I put into an engine came with a spec sheet (as all pistons should), they stated for an 82mm bore to use .0765mm (basically .003") clearance.
