R34 Gtr Power Output?

[mass_iv]

Hi Guys,

Need a bit of help on fuel pump setup..

I dont want to go surge tank so im looking for an intank pump that will be able to flow enough to pump out 350awkw roughly

will a bosch 023 do it?

Iv got all supporting mods, nismo FPR and sard 800cc injectors.

Opinions please? would rather hear from guys who have setups making this kind of power and what they used to get there.. Ideally i want to go more then 350awkw however i think that will require a turbo upgrade again...

Thanks

Mass

Bosch 044 - 380kw.

Can be mounted in-tank with a bit of mucking around.

[mass_iv]

Thats wat i was thinking, i heard it can be with a sock on the end etc.....

800's will do over 400rwkw so you dont need a FPR at all.

If you have the -5's, no reason you wont make 350, plenty of pumps drop in (any jap ones) and probably a bosch for the power

[mass_iv]

yeh iv already got the FPR from previous mods, now upgrading the injectors hence why i have an fpr and 800cc inj....

I was just a little hesitant with using the 044 intank.. Iv decided to drop in the 044, and yes iv got the -5's so im looking at pumping out 350.

One more question for those that know,

What do the stock AFM's run out of puff at?

Do i need to go for Z32's? i was looking at getting them but unsure as to wat the stockies flow awkw wise????

[Bakes]

What boost are you gonna run Mass? Your still on stock internals like me, correct?

My set up is similar to yours but with different ECU. Ive got ~300AWKW at 1.2 Bar.

Im far from an expert but in the research I did, most people with 350AWKW upgraded their air flow metres to Z32s

hey there

ive got the nismo drop in pump, nice and quite, -5's no problem with them

cheers

I bet its at least x3 the cost of the 044.

I made 326 on 17psi with standard afms...you will require about 20psi to make 350odd, so depending on your tuner the afms may need upgrading.

I have a single Z32 afm and did make 380. Dont know how the tuner did it but he did...its all in the tune!!

[mass_iv]

hey guys,

thanks for the input so far....

Not stock internals anymore... engine is currently stripped and being built... its having the full treatment, forged internals, cams and sump etc.....

i was looking at a pfc d jetro instead of the Z32's but i think i might play it safe and just go Z32's with the pfc iv already got...

Only other thing i need to look at now is coil packs... tossing up between JJR and Splitfires??? not sure on the differences?

[mass_iv]

as for boost, Bakes i was running 1.2 bar also and made 300awkw...

ill be running more like 1.5 bar this time round with the built motor and upgraded fuel setup..

Hey guys, just a question out of curiosity as I begin stage 1 mods, but what are most of you running, 80mm or 90mm exhausts on your GTR's? I have an R34 GTR Nur with the N1 engine etc. Does the extra size really make that much difference in power?

Cheers,

Ed

[R31Nismoid]

Makes all the difference - 90mm at least

[Bumblebee]

102mm all the way!

Sounds good Mass. Good luck with it all.

Whats wrong with stock coil packs? Buy the HKS Twin Spark and you will have no issues!

[R31Nismoid]

Well if his are failing - then ye. Otherwise stock are fine

R34 packs are a bit problematic though for newie's for some reason

[mass_iv]

Thanks guys....

As far as i know my coils are fine, not failing, but i dont want to throw it on the dyno up the boost and find its suffering coz of coils....

So i thought the JJR's are a good cheap alternative, however unsure on quality???

Dunno bout the HKS twin spark? wat is it?
