I have HKS 256IN/264EX with Tomei valve spring you can have for $1000.

I kept factory cams upto 370rwkw.

Guilt-Toy kept factory cams to 350rwkw on a 25/30 as well.

Talk to your tuner and see what they reccomend as OEM isn't neccesarily a bad thing

[26ame]

Serious... That's crazy power

what else would you suggest to crack the 300kw then?

[R31Nismoid]

More boost.

[26ame]

Motor is still unopen tho...

Don't want to push it too hard..

[R31Nismoid]

What do you want to achieve exactly?

[26ame]

I want to crack the 300kw mark but want more power

the motor will be built later down the track..

[R31Nismoid]

You want to get over 300rwkw but don't want to push it to hard.

That is kinda mutually exclusive mate.

[26ame]

don't get me wrong... i will push it hard

when the motor is built for it

so otherwise what your tryin to say... i can't do anything more for the meantime til i build my motor yeah....

and 300kw is down the track mark... more then likely puttin more boost into her when she is built

ive been down this road mate.

I went for 240rwkw, that i could thrash all day every day and be perfectly safe, instead of getting 300kw and thrashing it till it went BANG.

You dont want 300kw if it will only last for 1 outing

WMI is your friend................

Hang on, 300kw on an unopened RB25 is so last whatever... Every man and his dog is running that without any issues.

Push 20psi on a good tune and see what happens, people are doing a lazy 300kw on 17psi on 3076s left right and centre... Ill be one of them soon.

[wolverine]

Who is making 300rwkw @ 17psi?

Most seem to be around the 270-280rwkw mark from what I have seen.

[KiwiRS4T]

Ref the RB25 upgrade thread.

Post 625 Lithium has been running around 270kw with his GT3076 on an unopened engine for years now at 301kw @ 17psi

Post 629 Simon GT3076 310 kw @ 17psi

[26ame]

your spot on.. i've hit the 280kw mark... on 17psi

but i've got a greddy t67 10cm and unsure what is the best boost to put in them yet alone what is max boost.
