Hey guys, quick run down. Building my r33 gtr with 2860-5's with all of the usual supporting mods. I am now currently searching for injectors and have been offered quite a few different kinds by helpful members. They are:

-Power enterprise 800cc

-seimans 750cc

-sard 700cc

I'm guessing they roughly all flow the same, but may have different spray patterns ect. And was wondering which ones would better suit my goals.

All injectors have decently low k's on them and similarly priced.

Which ones would you choose and why?

Why would different cc injectors flow the same?

Power goal plays a big part in it. Need to know what fuel you want to run as well because if you plan on using e85 you will need larger injectors then if just running pump fuel

Only planning to use 98, not touching e85. And not going to use id1000, no point? I'm asking what injector that I mentioned in my initial post would you choose and why as I can get them for an extreemly good price.

There was a reason why I suggested what I suggested. The ID's will drive a lot nicer than the "older" Sard/Denso injectors.

ID's are cheap enough now, it shouldn't even be a factor.

Theres lots of points as to why you should choose the ID1000's & lots of points as to why you wouldnt bother using 2nd hand injectors. ID's are the best injectors on the market and are probably a few hunge more than the 2nd hand shitters ya planning on using. IF you are worried about spray patterns etc for good combustion theres only 1 choice! ;)

Thats the ID's!

As piggaz said the ID's drive alot better than anything else. Im running ID2000's in my evo and it runs like a dream idlea sweet and I get surprisingly good mileage outta a tank of E85

I think Xspurt do a 740 based on the kompact (short) EV14K . ID do an 850 GM based on the short EV14s as well . Actually the ID1300s are shorty's as well from memory .

Short EV14s do fit under the plenum on a 33 spec RB25 but you need a rail to suit 14mm injectors . People say modified RB25 Neo rails can work with a bit of stuffing around .

I think they were reselling the proflow RB25 rail, they were a little more expensive at around $200 I think, but great quality.

You can get 14mm rails for under $100 if you search around (egay, goodies direct etc) not sure on their quality though as I have never fitted one. You will need to work out injector spacing and brackets so they hold down tight.

The Xspurt 1000's drop straight into the RB26 with the kits I sell. No spacing required from stock, and the plug adapters are supplied.

      DeAgostini 1/8 scale BNR32 Nissan Skyline GT-R Nismo

      By Rezz · Posted

      Starting with issues 1 - 5, we have already run into a problem...!  Issue #4 contained 2x front brake calipers, instead of 1 caliper and 1x steering knuckle. Will have to call DeAgostini on Monday to sort it out. Anyway here's some photos.  Issue #1 is the front bumper, headlights and number plate. Issue #2 is the front wheel (with "We produced with spartan air." text on the centre cap!) and tyre, the front lip spoiler and cylinder head cover with ignition coils under the centre cover... which will never be seen again. Issue #3 is the bonnet and cylinder head. Issue #4 is the front strut, brake disc (with laser etched metal discs) and brake caliper. I stopped here because of the issue with the missing steering knuckle.  Next update will be #5 - #10 in a few weeks.

      DeAgostini 1/8 scale BNR32 Nissan Skyline GT-R Nismo

      By Rezz · Posted

      DeAgostini is one of a few companies that release quite large (the largest commonly available size actually) 1/8 scale models in a series of weekly issues over 100 - 110 instalments.  They release different models for different markets and DeAgostini Japan have release the BNR32 Skyline GT-R Nismo last month. I've made two of these 1/8 scale sized cars (one an R35 GT-R from 2012 - 2014, the other I'm just about halfway through, a BNR34 Skyline GT-R from the 2Fast 2Furious movie) so when this R32 was announced there was no way I could ignore it as it's my favourite out of all Nissans.  Each issue costs around $20 so it costs about $2.2K when completed. I suppose it is very expensive for what it is, but the quality and details are really very good, and there are many "gimmicks" like fully functioning exterior and interior lights operated with a remote control, working steering, all doors/bonnet/boot/fuel lid open and close, the side mirrors fold in and it even has a speaker for the engine revving sounds when you turn the lights on.  Each issue comes with a magazine that tells the story of the BNR32 Skyline GT-R Nismo from the first design stages of the BNR32 to Group A homologation and the various racing version that were run in the Japanese Group A and JGTC, and Australian Group A.  So I plan to update the build in this thread 5 issues at a time.  https://deagostini.jp/r32/?srsltid=AfmBOooKjxDc4EUK2rmXqMBPgyHfFJ24s4oEPJBNpnF-lFlsRoW0PE6P

      Help Understand GTT Boost Setup

      This would be a new pump with new gears. I'm just unclear on whether it's a good idea to run more oil pump flow if you don't actually need said flow. Oil level is set a minute or so after shutting off a warm engine so wouldn't the high RPM oil level in the sump end up lower all things equal? Plan is OEM clearances, main concern in my mind is whether the OEM pump can keep up with the flow requirements of any additional oil coolers.
