the size i carnt quite rember ,but not that big aroung the 215-220 as a rule but does vary and the stock afm runs out at around the same ,so you need a higher resoulution one ie, z32 but you will need a pfc or some form of piggy back setup ie.safc to run the afm, what are you wanting to do with the car and what is alredy done to it, and power goal.

If i'm not wrong it'll be about 140ish rwkw stock as i saw my mate's GTT with just pod and full exhaust ran a 160ish rwkw on the dyno.

Stock injectors will definitely support 200rwkw. It'll be JUST right. Yes with stock AFM as well. Any higher than that, you might consider changing.

I said this in another topic but may be of interest in here as well.

For the reference also the R34 RB25 Neo injectors are top feed high impedence 370cc.

Unsure if you remember or not but on the High Performance Imports DVD's they did a skyline dyno with different mods on an R34GTT.

This engine has higher output compared to R33 model (206kw vs 187kw)

On the Croydon Dyno Dynamics Dyno it pulled the following figures.

1. 100% Stock R34 GTT Car 148rwkw (R33 should be less then this power)

2. 3" Turbo Back Exhaust - 158rwkw (stock cat still)

3. Boost increase to 10psi - 181rwkw (remember R34 has bigger turbine housing)

4. FMIC & 13psi boost - 200rwkw

5. GCG Highflow, 14psi boost + PowerFC - 225rwkw (injectors 100% duty no more boost can be added safely)

Hope that can bring something to convo as well.

So with a GCG highflow along with my PFC and intercooler I could run around 225rwkw with standard injectors, fuel pump, and airflow meter? Do the fuel pump and afm become inadequate around the same time as the injectors?

I've actually got that DVD with me. The whole process was seperated into 3 parts. They put in the hi-flowed turbo because it blew when they brought their black R34 to the track. Think it's called HPI-34. In the end, the car was running about 260rwkw? or something around that big power region.

Do not run your stock turbo at 14psi ( 1 bar ) for daily driving. :wave:

    • See, that button sounds like perfection Duncan! My eyes really don't like light shining at them from a dash when I'm driving. Being part red colourblind, I've found for most cars that I can change colours on, I set everything to red, so my eyes see the elast amount of colour! I miss normal gauges in cars
    • bro, knowing the Japanese in  the 90's, i wouldn't be surprised if they shared components across their model lineup.
    • Maaaan so many "little" things  i rly hope my old RB20 would be "ok" and not too bad. I try to learn what and what not do i need. I look at crossmember at it looks different...even parts numbers are different. Wiring and all that i rly do not know...yeah someone mentioned the speedo thing. On that yoke clip. I rly do not know what can and cant be done "custom" so that is why iam asking to know and not be suprised 馃檪  I know what it looks like  
    • Oh, there's also the gearbox crossmember which will probably be different between the small box and the big box, and the wiring loom will probably need to be modified, because the plugs for the switches etc, will probably be different. And I think the speedo on the small box R34s is from somwhere stupid, like the diff, possibly, so you'd need to work out what needs to be done about that (assuming it is different). I think the thing you need to realise is that the front end of that yoke is a large hollow tube with splines on the inside that mates with the splines on the box's output shaft. It is a dedicated thing - not available "aftermarket". They were made to suit that box, by the car's OEM.
