Currently doing mains, soon to do rods. Ive miced and used a dial bore. Ive gotten a wide range of clearances, so i cant decide how to go with it...
Ive got HX y and H shells on hand, ACL Race Series.
I can either go all 0.0025" (ranging within 0.0002) or 0.002" (same as before), cant decide which way to go, this engine will have over 450hp, revved to 8k or maybe 7.5k to be safe. Purely a drift engine. First time going this deep into an RB, last time i got a stock engine refreshed with full HX, dont remember my clearance but it was loose, engine lasted a year until oil starvation got it.
