	Nissan GT-R injectors « on: December 17, 2018, 08:27:10 AM »

Hi guys!

Really need your opinions and advices.

I build 2.7 allroad on rs6 ko4 turbos, and I bought injectors Denso from nissan gt-r r35.

the choise is due to good performance and good cone (12 nozzles).

So, is anybody use it on 2.7 or I'm first idiot?)

Google didn't have a lot of info about this injectors, just 570 cc, and I can't find any datasheet.

570cc is kinda small, which is probably why nobody has used them.

well, 570 cc with 3 bar, so about 660 cc with 4 bar. Enought for my requests

There is many typical projects with 550 cc bosch ev14 and k04 in my country (Russia), about 500 hp, I decide be more individual

think that good cone can do more homogeneous fuel charge (sorry for my english).

hope that anybody will can tell me some info (voltage offset, fkkvs)

It is years since I worked on R35 GTR but the stock ECU latency was about 0.9ms and about the same gradient per volt. Sorry I cannot remeber if the latency value was at 12 or 14.4V.

We have used it on our drift nissan 200sx project, it have 2 td04 turbos from impreza wrx and made solid 450 whp on completely stock engine.
If you are not aiming for more than 450 hp - you can use it, it will give you perfect idle, low fuel consumption and will last long

Great! You're from Kazahstan? I saw some blue SX on drive2 with 2.7t.

Can you tell me please tvub and fkkvs parameters? For injector migration its enought or something else?
Are u use 4 bar regulator?

P.s I found some data on gtr-heritage:

Flow 570cc;

Latency
8v - 2.858 ms
9v - 2.678 ms
10v - 2.499 ms
11v - 2.319 ms
12v - 2.139 ms
13v - 1.960 ms
14v - 1.780 ms;

Injector minimum open time 1.83 ms;
Injector lag time offset 0.890.

Yes, I'm from Kazakhstan
This car is working on LINK ECU with traditional fueling ( 3d table with injector opening time) model
So there is NO injector flow
But we use 4bar regulator
and latency is 1.1ms at 14v in our case
