budget head = arps / metal hg / bc 272's w/ bc springs and retainers...

sounds like a diesel but gets you past 400.

In my dictionary...
"A stock bottom SR will reliably make over 450"....
Which means that given 100 SR's with the same mods,
99 of them will make over 450 when dynoed.
How many times they will do this is not guaranteed.

About 350-360rwhp in my experience is a safe repetitive... go beat on it number for a stock bottom end.


How much power you want to push as a daily driver / weekend drift car is totally dictated by your wallet.
