R33 Gts-t Injector Options

[L33igh]

This question may seem a little jewish, but here goes...

Are there any injectors that are standard equipment on another car that would work well as an upgrade for a mildly modded 33 GTS-T?

Further more, any truth to the rumour that XR6T injectors will work? I understand that the 33 has 'side-feed' units, am not sure what the XR has, but any input would be great. I am aiming loosly at around 250rwkW, not fussed, but dont want to starve things.

[dead32]

xr6T injectors are top feed, you can buy adaptor rails to run topfeed on rb25 but then you needa change injector plugs etc, or you could try source 6 jdm s15 injectors which are around 480cc? correct me if im wroung that should supply that power level?

[moonus]

yeh s15 injectors are they way to go if your on a budget, based on severel peoples experiences, and apparently they can be from any manual s15, not just the jap spec.

[L33igh]

Thanks guys, I would never believed that the squirters on a 2ltr 4-pot are that big! What would you expect to pay for these?

And do you know of anyone who has run them before? I'd be keen to know their limits, naturally, without finding out the hard way!

[L33igh]

P.S; A little research tells me that they are 440cc injectors...still sustain around 250rwkW you think?

[moonus]

easily handle that power, ull be lucky to get some for a few hundred dollars. ask Burnsie

Yeah ask me !

Haha.

I would rate them at 450cc.

Getting tuned tomorrow hopefully (take 2 with a REAL AFM) with a HKS2535 and all supporting mods.

Supprised by the size of the injectors hey?

Wellllll.....

2.5 / 6 (cylinders) = 416cc per cylinder

2.0 / 4 (cylinders) = 500cc per cylinder

Not so confusing now is it ?

Yeah, so easy swap out .....(DIY available in the appropriate sub-section)

And heaps of info .... http://www.skylinesaustralia.com/forums/in...146846&st=0

Hey, Where abouts did you get those injectors. were they new from nissan or did you find a wreak?

also are S14 injectors the same or are they 370cc like the RB25?

[moonus]

hey man, if you want them cheaper, your best off sourcing them from a wreck or someone with an s15, whose upgraded. best look through nissansilvia.com. s14 injectors are 380 cc

[zebra]

Cheers mate...still thinking i might go the top feed 660cc siemens that ive been looking at as im probly gonna be chasing around 300rwkw eventually.

problem is my stock injectors are nearly maxing out at .8bar on the stock turbo.

hopefully an 040 pump will fix that.

hey mate, why dont you just go for drop in side feed injectors instead of top feed, such as tomei or nismo 740 cc injectors. Slide has them for $895 delivered. do you know what duty cycle your injectors are running. id say get a fuel reg as well if you want a quick fix solution to your injectors maxing out

[zebra]

Yeah Drop ins are probly easier lol.

duty cycle gets up to 94-96%

so i def need a new fuel pump at the least

[Birnie]

I got one set from Slide Imports, brand new with a GTR R33 fuel pump for about $300

But thats for brand newies with all the rubber thingos to go with, see pics in the s15 thread i posted earlier.

2nd set from a written off S15 in Aus.

$250 delivered for 4 out of a 2002 model.

You should be able to pick up 2 sets for about $400-$450 and then try selling 2 like me and come out about $300 out of pocket which aint too bad

forget any other model eg. s12/13/14, no good to you if they are standard injectors,

s15 manual ones are the only 450-480cc injectors.

[zebra]

Cheers mate,

Will check it out

Birnie, might buy those 2 injectors off you just depends on funds avaliable next week. will keep you posted.

[Bliksem]

Hope this doesnt make the decision any more difficult but www.deatschwerks.com sell overhauled 450cc injectors with new o rings etc and send cash your way if you trade in your old ones.

[zebra]

Yeah thats in US dollars Though. works out to be around the same price as buying new 555/740s and selling my 370s

[L33igh]

Awesome, thanks for all the feedback, S15's squirters it is. Cheers Burnie! $$$-permitting I may take those 2 from you if zebra dont beat me to it.

Otherwise thanks again for your help!

[zebra]

Lol Its a race.

[Birnie]

1st one to PM me with cash ready to go gets em
