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.

    • Fark what are the changes of that snapping like that, clean. Nek minnit, custom radiator goes in, with built in oil cooler like those discontinued PWR ones from yesterdeacades ago
    • I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....
    • So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.
    • our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
