Astina 1.8 Power limitation by parts
 

Hi guys,

I was wondering what are the maximum WHP you can safely run on stock parts?

Example - Stock diff / Stock clutch / Stock transmission / axle / cooling system

PS.
I already have a upgraded fuel pump / bigger injectors / coil on plug setup / standalone ecu + Miata NB pistons + metal head gasket + ITB + 2.5 inch Stainless steel exhaust.

I'm making 140WHP at the moment and starting to upgrade to Toda cams + porting heads for the 2nd time. So maybe I will make around 160WHP at the end of Cams (hopefully I can use the potential of ITB properly) + porting.
