What size blox should i put on my PnP stock manifold. I read some say 72 also read 74. Im not against doing a spacer either. I can port match myself.
What other t body options are there. I don't think the max bore is worth the money.
thanks guys

 

I am also curious to know this information. I am planning on boring out the OEM TB to the largest size; anyone know what that is? Thank you!

 

I've seen a few use the Blox 74mm TB. I think you need to find a way to get vacuum before and after the blade. Not a lot of info on it.

 

Seems a waste if you're not FI.

 

What is the biggest size you can bore the OEM TB?
