Wanting Over 350 Rwkw

[teazn_r33]

hi pplz i need a lil bit help

im chasing 350rwkw i had 300 but was to laggy

im getting the heads posted and polised today and new valve springs

also looking into some low comp pistons, maybe a gt35/40 also some stonger rod bolts i have the ignition setup already and fuel set up

i need some ideas the more the better also i also have a high mount manifold waste gate and im after some ideas for ecu

thanks

hang on, you just said 300rwkw was too laggy but you want more power? dont expect less lag? have you considered a 3 litre bottom end? adding another 50rwkw is only going to add "more lag" if you don't make the engine more efficient at the same boost level and / or turbocharger size

[pnblight]

what cams are you running?

[rob82]

Raise the compression!!

much what i was thinking

[teazn_r33]

pnblight- thats wat i want to know

paulr33- the setup i was using was a lil lagy for my liking as thats y im after ball bearing now

[R31Nismoid]

well what was your old setup?

And what do you class it as being late spooling?

[Space Goat]

a healthy shot of nitrous will help you get there for a split second or two

this is just a idea n i dun no much bout the rb25s but im about 2 (rb25det neo coming for my r31 wagon this weekend :-D )... its prolly too late to say this now and might be innefective but wat about a neo head would your computer handle variable valve timing???... that got em a extra 30 kw or so along with bigger coil packs n some other stuff (pretty sure)

[R31Nismoid]

wat about a neo head would your computer handle variable valve timing???

He already has an RB25... why does he need a neo head?

i got an RB25 with RB30 bottom end, T78 Turbo and a microtech ECU thats it, its expecting to make close to 330rwkw once fully tuned.

lag's not too much of a problem, boost kicks in bout 3000rpm.

i got rb25/30 with td07s with t04r comp wheel and back cut t66 turbine wheel, made 352rwkw on 16psi and hardly any lag...

good ol 3 litre block

ben...

[teazn_r33]

not bad thanks pplz i dint think ill be going to the 3lt bottom end would love to but cash might be a issue how hard is it to do

and wat does it cost

i had a t70 was a bit laggy but i still producced just over 300 rwkw on 19psi i think i want a high mount and also a ball bearing turbo for quicker spool

i need to know has anyone reground there cams as i heard this is a option instead of buying some

[KamikazeR33]

cheaper to buy new cams

[R31Nismoid]

what do you class as a bit laggy?

like, i mean a given RPM, not just "saying" its laggy.

Hell it might have been as good as your gonna get!

[Rolls]

your not giving us enough info to work with mate.

What was the details of your old setup, what rpm do you class as laggy, how much do you have to spend etc.

[teazn_r33]

5000 rpm

im getting a high mount

need to know wat turbo to use i wat it earlier than that

i had a t70 standard manifold with custom dump pipe setup bosch 044 spitfires now im getting port and polish also wat are the best pistons im goin 20thou over

[R31Nismoid]

well my GT30 used to get on the money (17psi) around 4000-4200rpm, thats on the street, no "preloading" on a dyno or whatever.

That was 300rwkw at a max with that.

You want a bigger GT35, 350rwkw... its gonna be a little better than what you have now... maybe 500rpm at a stab.

[KamikazeR33]

removing the stock manifold will give u a few kws aswell

[SLY33]

Raise the compression!!

<{POST_SNAPBACK}>

exactly!! whats with this low compression piston crap!? you can still run plenty of boost even with the std 9:1 CR, and it will give you nice crisp off boost response plus earlier spooling than lower CR.

[teazn_r33]

so leave the std compression i got a high mount so thats goin on and port and polish should help wats the pistons to get pplz
