Ok I have upgraded my rb25 skyline with the following mods:

Walbro fuel pump
Q45 airflow meter
Deatchwerks 550cc injectors
Ngk iridium 8 plugs

I have tried to start it and it seems to want to go but just wont.

I have checked the plugs, fuel pump and the airflow meter. I'm a little concerned about the injectors. The photo is not great but as you can see the inlet gauze filter is in a different place and i'm worried that this might be the problem.

My power fc is set at 69% injector duty and 0.04ms latency.


Any help please!!!!

whip out a plug or too and see what they are like - would it be possible that you have flooded it a bit with the larger injectors?

(just a thought - im still learning my way round the RB25)

Before I started any work the car was running fine apart from the turbo oil seals. I have fuel pressure and new iridiums. I have a bad feeling the injectors are wrong but I can not be sure.

if you have just dumped in larger injectors without correcting for the increase in fuelling, you will have flooded the engine (at least thats what I reckon)

Thats easier said than done. I want to get it started to get it to the tuner who is 200 miles away.

Agreed with above about getting it mapped, but try putting the old injectors back in if you think that is the problem
