Might as well chuck mine into the mix... 187rwkw. Manual car.

Current mods:

HKS turbo back 3" exhaust - Silent Hi-power

X-Force 3" Cat

Hybrid FMIC

HKS POD

Cold air box

Power FC

Greddy Profec B-spec II

NGK Plugs @ 0.8

Running 12psi, moderate tune.

Mods to come to break well into the 200's:

HKS GT2835 ProS

Tomei poncams

Walbro Fuel pump

550cc+ injectors

Plazmaman plenum

Splitfire coilpack

Z32 AFM

Prior to all that it was running at 158rwkw. Same as yours. Dyno Dynamics dyno.

187rwkw WITH power fc? bit low isn't it?

anyways, it's pretty easy to work out. Take an average of 150rwkw for a GTT, that's a 28% drive train loss from the fly-wheel.

My aim is 300kw at the fly, giving me about a 215rwkw target, give or take.

So just do ~30% drive train loss. This does vary from car to car

I have some misfiring issues that are still being worked out, hence the new coilpack etc to come. Half the time she's running on 5 cylinders. Also a bit suss on the history of the car.

aaaahh dodgy coilpacks, all too common problem with the 34's unfortunately.

mine went, i got splitfires now. Not too major a problem and easily fixed. Have you tried the DIY solutions for it?

Coilpacks were a common problem for the GTT R34's is it? So i would expect some missfires to come after some mods too? Does anyone gap down plugs on R34's for misses?

Yes.

When the boost is increased.

Yes to 0.8 mm.

I thought we were almost at consensus that drivetrain losses are not are percentage, more of a certain amount of power for each car; ie the same number of kw no matter what the total power.

Evil34, is that your car in your avatar? If so do you have any more pics?

Coilpacks seem to be a problem with Skylines in general. I don't think I know a Skyline owner who hasn't had some sort of issue with misses.

Anyway, splitfires fix em up just fine. Price you pay for greatness.

I've got some money to pour into the car, so I am just going to bite the bullet and get it fixed permanently :P Along with the other mods I listed... needless to say I am looking forward to it.

Currently after a tune yesterday my car sits at 184 rwkw on .75 Bar.

My mods so far are:

Splitfire coil packs

Walbro fuel pump

Drift pod filter

Blitz front mount

3 inch turbo back exhaust

Platinum spark plugs gapped to 0.8

AVCR boost controller

They could not put anymore boost into the car due to the standard computer pulling timing and dumping fuel at any higher boost level.

I have the next round of mods sitting at home now ready to go in which are:

Power FC

550cc Injectors

Z32 airflow meter

just ran out of money to fit this stuff at the moment

Is this on Stock Turbo???? i'm about to get my PowerFC tuned..

158 is in the ball park. I'd say 145-155rwkw mark would be around what it would make.

I wanted to confirm if that's still correct because when you go to any automotive website like Supercheap auto for example, it only gives an option for an r34 gtt that has 206kw, which is same as a gtr r34 roughly. Makes no sense to me lol.

Manufacturers quote power at the engine, we quote power at the wheels, which will always be lower due to drivetrain losses.

The GTT's Neo actually did produce ~206kW at the flywheel.

The 34GTR's 26 really did not produce 206kW at the flywheel. By the time the 34 came around the 26 was likely up around 230-240 kW, and probably could have been more. The Japanese manufacturer's had an agreement to not sell any cars that made more than 206kW (actuall, their agreement was expressed in the stupid non-metric German ps units which is essentially horsepower, and the numerical value in the agreement was 280ps).

So Evos, Supras, GTRs, 3000GTs, and so on, all had official 206kW power outputs published, and all made variously larger numbers than that. Even the R32 GTR made a decent margin over the official number, all the way back in 1989. As you'd bloody well hope for a TT 2.6l 24v engine running ~12psi of boost.

The old "Gentleman's agreement". 

They all kept publishing that number to avoid government intervention.

They all kept pushing over it to be quicker than the other guy.

 

It's why I'll say it's smart the Gen4 Supra was more suited/targetted to taking on freeway runs, than taking on the GTR directly. Nissan and Yoda rivalry slightly more apart receiving a little less criticism compared to the Holden Vs Ford in the years gone by with the likes of the GTHO etc.

Ah Interesting to know.

      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.

      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.
