i am looking at building a rb30 for my mercedes and wana know how much power i could get out of a stock rb30 na motor with maaybe just forged rods and all race bearings i wana put a t70 on it will it hold around 400 with a good tune or just fuck up on me and its gettin a rb25 head on it with a jatco 4spd your thoughts a really appreciated

why dont u just 1j it will make that power easy

i had a manual one but thats in my cressy and i got a couple of rb30's cheap and a mates got a 25 head

pretty general question. but logic says if everythings done right it will hold 400 and not fuck up on you.

Hold 400 fine mate.

350 would be heap but wats the go with the istons or just put a thick headgasket on it or decomp plate

Why dont you ask the place in your signature?
