Hi Andre, I am currently building a 2.3L stroker 4g63 out of an Evo. What clearances do you recommend for daily driving and occasional spirited driving?


The clearances I listed above are still absolutely fine for a street application making more power than stock. You'll note that these clearances are still within the limits of the stock recommendations so there's no real issue to using them.
