I had 255rwkw with stock injectors fuel pump and turbos before upgrading. The tuner advised at that point that my AFM were maxed out but the injectors were fine. I only just upgraded to nismo 600cc so if you're after some R34 gtr injectors I've a set for sale so PM me if you're interested mate...

Doesnt sound right... anyway nothing is the same when you're comparing old cars.

Just to give TS an idea, I know someone on the forum with another 33 N1 that has 330rwkw with close to 98% injector duty cycle and the only mod he's done are ecu, avcr, catback and cat (not 100% sure about cat but should be right). The only difference between N1s and standard gtrs are the engine, oil cooler, oil pump, water pump and no a/c. The other features doesnt really affect your power as much anyway (kelvar front diffuser etc).

Having said that, thats with an aggressive tune according to him and mine's running a safe tune with 255awkw at less than 90% duty cycle.

Hey mate just wondering what doesn't sound right? The maxed out AFMs at 255rwkw? It was Dr Drift who did that original tune and who provided that advice.

Yes, they should not be any where near maxing out at 255kW.

+1. Never heard of anyone maxing out stock afm around 300awkw. Stock items should be sufficient for that but I must agree, injectors, fpr and fuel pump are very nice to have items to archieve that. Maybe check if the afm you have now are clean and in sound condition.

I think the difference between them are side and top feed + low impedance (gtr).

Ok doing some research found a old topic (search feature didn't work found through google.)

http://www.skylinesaustralia.com/forums/Gt...det-t62674.html

In all gtr injectors fit but u need the resistor pack and u gotta do some soldering :thumbsup:

but i dont think that hassle is worth it coz if u get different injectors later on taking off the resistor pack again will be draining... but i dunno if you will need to meh...

Check out my thread for info on how to fit the resistor pack. A bit simpler than ripping apart the whole loom.

Meh, higher than 85% is ok if they are in good nick.

You'll end up leaning out, if you want to blow your engine run your injectors at 90% duty cycle + for a small period of time and watch what happens :(

The injectors go static and your fuel delivery goes out the window, you'll end up with a blown head.

A tuner shouldn't be tuning your injectors to run close to 100%, if he is, then he is a moron and just wants you back into the shop so he can rebuild your engine and get some extra cash :laugh:

I don't really reccomend the resistor packs, they are usually dodgy, spend the extra and get a FJO Injector Driver and it will work properly.

I already know of someone who ran Targa with 98% (max) a couple of times.

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      R34 25GT Engine Light 21

      By CF.Panda · Posted

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
