Title: Pre chambers,,
Post by: TUFFY on March 26, 2013, 12:38:23 pm

Hello, Is there any difference in factory turbo pre chambers compared to the NA pre chambers? I am not sure what most of you guys call them lol.

Yes, they are a different size.

Can turbo ones be installed in a NA head?

If memory serves, the TD ones are slightly smaller in diameter than the NA ones and so, no, they will not work in an n/a head.  The n/a ones could be installed in a TD head if it is machined to fit them.  I could have that backwards, tho.

no. The 1.5L and 1.6 TD are 30mm across the face. The N/A prechambers are 32mm across the face. Being a press fit there is no way to install them easily.

Edit: libby was in there the same time I was. Carry on.

OK, I am stuck with NA ones then. Would there be much power difference on a high boost lots of fuel 1.6 between the turbo and NA chambers?

No.  There wouldn't be any difference at all.
