Port and Polish sr20det

good power for a 2L, who mapped it?

he mapped it himself. i would assume using link management of some sort.

his username might give that one away

no heard different lad, correct me if im wrong thats why im asking

[tweek]

port and polish is only an advanage on N/A engines.

was goin to do it when i was building my own but alot of work for no advantage.

Really????

Would the ported head not spool the turbo quicker??

It does not work like that, without going into it too much, if you port a head bigger than the size where it is efficient it slows the air down as it's passing through, you need to find the size that makes the air move as fast as possible and more often than not the standard size will be very close to perfect. It's not all about air quantity it's much more about air speed! It's only when your going for monster power on some not all engines you will need to port the head. It has nothing to do with forced induction or n/a, it's about making the head as efficient as possible.

Yeah built and mapped by me... Using an older LINK G3 ecu
Machine work done By PowerMax Engineering...

More power left in it yet...Watch this space...:P

Theres no black and white answer, it depends on the engine, my B230FK got great gains from a port and polish on the head, manifolds and turbo.
