Have you done head work? I/H/E?

[JasonGilholme]

it would still run without being tuned, but to get the full benefit a tune wouldn't hurt at all.

But to get the full benefit surely you should build the head.

You don't really need a bigger TB unless the engine needs to breathe a lot more (IE post head-work).

[JasonGilholme]

Not always, vtec engines love to breathe. and a small increase above stock can give a nice result. If you go too big though you can run into troubles with low RPM bogging etc.

if you're going for a BIG TB then you'd assume headwork has/will be done. :thumbsup:

I have done my intake and a catback exhaust is on the way. Not thinking about a hard core TB upgrade, looking at something like the JDMyard TB porting. What does everyone think of the P2R plenum box?
