Hi,

Just wondering if any of you guys ar girls know what flow rate and colour these injectors are? (R32 GTS25)

I know that they are top feed, and have heard that they are around the 270cc mark, but can't find a definate answer. I've seen a a dark pink/red set on one, but need to know if all GTS25's have these colour injectors and their flow.

Also does anyone know if the R33 wiring loom will fit onto the R32 GTS25 inlet manifold? (seeing as injectors are different, no VVT on 32 and maybe other things...)

The reason i'm asking is that i'm considering putting the 25 head on my spare 3 litre block, and i thought you NA guys would know. :D

Cheers

Benji

I have a RB25DE head also that I am dropping on to a RB30E block.

The injectors I pulled off it look exactly the same colour as a normal R32 RB20DET.

For some reason my RB20DET which is a 92 model has clear top injectors with a red dot on them?!? Maybe its been fiddled with as on high boost I recently tested to see how many kays I get out of a tank local driving to Uni and back, shops etc and I got 450km's when the light came on then by 510 the external fuel pump started to make that annoying noise telling me that fuel is around 10kays away from running out.

So now I've flicked to low boost gave the other half the controller with high boost turned off so I can't be tempted. :O

Should be interesting to see if there is any difference in fuel consumption.

Also as a note I do drive it hard always hitting full boost of 15-16psi drifting out of corners in second when boost hits hard and snapping second causing second gear to spin up with a slight snakey until 90km/h.

Thanks for the reply mate.

What colour did you say they were????

How far into your build are you?

It seems like your getting pretty good fuel economy. Last tank i got 450km. It took 58 litres to fill her.... so she was pretty empty. That's on an RB30ET, and not driving like my grandma either... :O

They are a red colour.

With regards to the build. Well The head is all ported and polished etc.

Before I sent the head off, I was unable to touch the front face of the exhaust valve, I am able to see the valve as clear as day and touch the front.

Before the work to the head the air flow would come up past the valve head up a little then do a 90degree turn to head out the port. Now there is no 90degree turn simply straight out :P

Should help the terbs spool a little quicker. :)

I'm now saving a few more $$ for the bottom end as i'm getting a little bit more done to it than I first planned.

Then again when I first set out for the RB30DET rebuild I didn't plan on rebuilding the head and porting it.

I'll post pics up when i get a hold of the camera.

I'd say max 2 months before its in. Hopefully.. :(

Money burns a hole in my pocket so I have to refrain from buying other bits and pieces along the way.

      Means something is not set up right, tune/calibration related.

      Finally replaced the previous temporary mesh indicator surrounds (temporary was the last 10+ years 😂) with a 3D printed GTR style version for the front indicators. I think it looks a lot nicer than the old setup and at least the indicators now point in the correct direction rather than angled off. Needed a little bit of tweaking to deal with the intercooler piping but got there in the end. Old and new photos below.

      It's weird to me that you say this because I'm pretty sure locals with relatively standard standalone tunes (boost/barometric compensated alpha-N) still have driveability issues when they pop intercooler hoses. Maybe with enough data I can just train some kind of model that spits out an expected grams/cyl given every sensor input except MAF like what FCA did with their Pentastar 3.6 ECU logic. Basically stock everything. The main motivation honestly is to have a sensor that can be a decent baseline source of truth. In scenarios you're describing obviously it won't work every time but it seems to me the number of corner cases that exist in MAF load is maybe not as severe and difficult to manage vs ITB alpha-N with some MAP/barometric compensation.

      What are your plans for your blow off valves? Purely plumb back? How soft will the spring in them be? AFM can be tricky to get super smooth and nice, especially depending on the rest of the system, and then can be very easily upset if something slightly changes. IE, even if you run recirc blow off valves, you could still see issues getting it to behave at certain load points as turbos might start to spool, but you release the throttle but it's not enough pressure to crack the bov open to recirc, and you can end up with reversion which can cause double metering, and hence dumping of fuel into the system, and stalling the engine.   If you're going to run a map sensor for closed loop boost control from the ECU, what makes you want to keep the AFM?

      It's not bad, it's just not flexible. And say if you have any leaks between the MAF and plenum, well then your load axis goes out the window. Here's a real world scenario, I blew off an intercooler hose last track day, as the clamp decided to Bluetooth itself somewhere. Still continued to do 2 laps and drive it to the pub for a couple of beers then home. Good luck doing that with a MAF setup
