They are 100% The R32 RB25DE injectors that came with bl4ck32 and my own head were both red top high imp injectors. I dropped a multimeter on them myself.. 100% high imp. Same part numbers everything.

The R32 RB25de's don't run a resistor pack of any kind, its not in the diagrams in the engine manual, only the rb26 does.

I'm sure mr_rbman could also confirm as he too ran a R32 RB25de head on his rb30.

Interestingly the injectors that came out of my rb20det were clear top with a red dot. Not that it has anything to do with r32 rb25de but I found it interesting. They must have run out of red plastic. ;)

;) he is correctomundo :ninja:

So you've got your self a set of R33 GTST 370cc Injectors?

How do you plan to fit them as they are sidefeed?

If your running a pfc you will obviously have to trim the injectors and also adjust the lag values for it to run correctly.

From memory the R32 RB20DET/RB25DE injectors run a 0.77ms lag time where as the R33 injectors are around the 0.54ms lag time.

gl with it! Dropped my 32 in today to get rb25'd (gearbox + engine) seems like a natural occurance these days :blink:

You going to be at DECA?

Also, where are all you ppl getting the R32 RB25DE heads/engines from? Ppl are asking RB25DET money for them :(

LOL...im going to be the last 20 running around :)

I am thinking of doing the same conversion but will hold out for some of the results.

I wonder how much boost you can safely run with 10:1 CR and how much timing you will have to pull out.

230rwkw and some torque is what I am after. I have everything already on the 20 and the turbo on the way. I am just missing some displacement :(

I was lucky and picked mine up through a mate who has a mate that runs a import place, lol. I dont think they know about the engine being able to mate up with the RB30 either and im gonna keep my mouth shut. Picked up my motor with all accesories flywheel and clutch for $495, not bad hey.

Yes we did discover that.. lol i forgot that was written in this thread!

I am pretty sure Nathan worked out which ones run at the correct impediance to run this DE+T engine.

anyone want to see more of her in the gearbox tunnel LOL!!1

:sick:

Don't you dare bitch!! :yucky:

Hi there, ive actually just put a RB25DE, +T into my R32 and removed all the hicas and fitted a lock bar. You said you put a spacer on the rack, just wondering what it was for?

here's some pics of the spacer..

" wonder how much boost you can safely run with 10:1 CR and how much timing you will have to pull out."

I was running 7psi in the R34 no problems, and it was making some good power. A final tune would have seen it with 9psi...but it was stolen before then. If I'd put bigger cams in I think 12psi could have been a real possibility with blinding performance.

Nice.. well the head's coming off it today so we'll see what happens!

Righty,that's why the confusion.Looks like you meant it was in the steering column,not the rack.Have you driven a car with one fitted? Any drawbacks to them?

No no i am putting spacers in the steering rack as well as the steering column (pics above)... they are called MAGIC WASHERS buddy!

A non-hicas S13 sreering rack and rear cradle are also being fitted.

and no i haven't driven a car with one fitted before...

Grab the s13 power steering filler bottle thing too as it only has one hose outlet on it, i just clamped a bolt onto the unused outlet for now until i get one.

Ive mucked around a fair bit with the wolf to get my idle, cold/hot start sorted out and the car is behaving perfect now, so its just 8 days away from dyno tuning.

I did drive it to get the aircon regassed, gave it a few half throttle hits and it had 7-8psi by about 2600rpm, on the freeway where i had space to play it was seeing 15psi just over 3000rpm but under load it just started to ping so i took it easy from then on.

As my wastegate has a 1 bar spring thats the boost ill be using, as long as i can control myself not to wind it up with the ebc.

It's quicker then any r32 rack (less turns from lock to lock! ...and then i have nice light steering and a fully locked rear end!!

Yep I am using one of them!!

Nice.. let me know how the tune went and the power output!

      All trim back in wired running driving. Few things to follow up on but not far off the return to the road. att.6HN4wP38LTIOISkhA8eACoBFqzfgQMahZPLA8ut0pqE.mp4 att.w2q0ux2PGuqgQTj2Os13cNHQtqcSEcCAhD_CAXy_IQM.mp4

      Mistakes were made, my R34 Story

      By GTSBoy · Posted

      The trouble with phone apps is that they really do not know the sensitivity of the mic on each specific phone, whether there is some sort of cover or skin that can change that, etc etc. So the readings off them are not calibrated. You certainly couldn't be sure that you were even within 3 dB. I have the same app on two (actually more than that) different phones/tablets and the readings in the same room at the same time are never the same. I don't mind the apps - they are as useful as a dyno - if you're testing for delta from thing1 to thing2. But not to try to generate some sort of absolute value.

      I'm gonna use the "Sound Meter" app from the Google Play Store and as close as I can bother to these procedures: 4. TEST METHOD FOR ALL VEHICLES EXCEPT PRE ADR83 IN-SERVICE GOODS VEHICLES AND OMNIBUSES 4.1 Microphone position 4.1.1 The microphone shall be directed towards the orifice of the exhaust outlet and shall be supported by a tripod or similar device not providing excessive acoustic reflection. The general requirements for positioning microphones are shown in the Appendix. 4.1.2 The nominal axis of maximum sensitivity of the microphone shall be substantially parallel to the test site surface and shall make an angle of 45 degrees ±10 degrees with the principal direction of gas flow from the exhaust. 4.1.3 In selecting the 45 degree alignment from the outlet of a motor vehicle fitted with two or more outlets, only the angle resulting in the microphone being farthest from any other outlet must be used. National Stationary Exhaust Noise Test Procedures for In-Service Motor Vehicles Page 3 4.1.4 The height of the microphone above the test site surface shall be equal to that of the orifice of the exhaust outlet ±25mm but shall not be less than 200mm above the test site surface. 4.1.5 The distance of the microphone from the exhaust outlet orifice shall be 500mm±25mm. 4.1.6 [Relates to vertical exhaust outlets] 4.1.7 For vehicles fitted with one exhaust outlet the microphone shall be placed so that the greatest possible distance is achieved between it and the vehicle. 4.1.8 [Relates to multi exhaust outlets] 4.1.9 [Relates to multi exhaust outlets] TLDR: 200mm off ground 45 degree angle relative to exhaust flow 500mm from tailpipe exit. (I probably won't use a tripod) Here's a photo, cause I read the instructions wrong myself.

      No ABS, no TCS, no airbags, no cruise control, no lane departure assist, no emergency brake assist, no orange lights in the mirrors (continuously annoying me in multi-lane traffic), no stupid rear view camera. I am the one responsible for where my car goes and how it does it.
