Injector upgrade???

[mass_iv]

Hi guys, ive been trying to find out a few things in regards to upgrading my injectors. ive got a r33 gtst, and ive just purchased a new GT30R turbo, Power FC, bosch 040, and am wondering if i should upgrade my injectors, as i am hoping to push for about 240-250 rwkw. i have all basic mods, FMIC, full exhaust etc.

my question is, if i chose to upgrade my injectors, what size should i go for, and is there anything involved in upgrading, ie do they fit straight in or is there any fuel rail modifactions that need to be done? and should i change my fuel pressure regualtor, i was thinking maybe a sard rising rate????

any help or thought relating to this would be appreciated

thanks

They will fit

thanks, oh and another question, when ordering there are two types, one says small and the other says long, does anyone know what the difference is, and which is the better for my series II?

They will fit

I'm pretty sure you also need injector collars for the Sard injectors - they're not a straight fit.

[R31Nismoid]

is they are SARD - ERC033 is correct.

pain in the ass.

Im using Nismo 740cc's. direct bolt in. there was like $40 in price between 550 and 740 so it wasnt an issue for me. Prefer less hassles.

[ECR033]

Once you include the cost of the collars, the Sard ones are no cheaper than the Nismo or HKS injectors. I'm not sure if there's any difference in performance between the 3 brands, but I'd think the Nismo or HKS ones are much less of a hassle to fit.

oh ok, cool thanks for that guys, ill prob get myself a set of nismo or hks ones then, since i like things simple, i was just trying to save on costs, but hey, if the sard ones wont fit and need more parts, ill rather spend a little extra and get the better ones....

R31nismoid- if u dont mind me asking, where did you get yours from and how much did they set u back?

[ECR033]

Nengun is your friend

I'm just about to purchase some Nismo 550cc injectors from then for just under $900 delivered (allow for GST/Duty etc just in case your shipped gets pulled up by customs). I've shopped around a fair bit, but haven't found anything cheaper.

[mass_iv]

how much would you be roughly looking at if u have to pay duty etc...

[ECR033]

This is what I was advised when I purchased a few items from Greenline earlier this year:

From our experience in Australia, the import system works as follows:

Cost of products + 15% (maximum) import duties + cost of shipping + 10% GST.

Note that for some parts such as engine management, there is 0% duties and 3% for turbos.

Although not a guarantee, we have found that small items under the value of AU$1000 are not generally inspected and pass through without the need to pay duties or GST.  We do what we can to minimise the tax that needs to be paid in the case where the package is inspected in Japan before the package is shipped.  Supplementary documentation can be supplied if required.  We advise that you contact the local customs authority if you require further information on importing into Australia.

I haven't had any problems with Customs as yet, but you should always budget for duty/GST etc...just in case. In a worse case scenario, it's still cheaper than buying the same item locally on most occassions.

Are nismo making a 550cc for RB25?

when i got mine i couldnt find any

so i just got some 740's... from nengun, was around $940 and i didnt get stung by customs

also be careful, I think the Powerdc requires a certain Impedance injector.

i think i might just get the nismo injector through nengun
