hey i recently brought a skyline r34 gtt everything is stock, so i decided to put it on the dyno to see what is puts out in only managed to do 184bhp (i think that it feels faster than that), i was told that they came stock with 280hp is that right, anyway i was devo when i saw the results so i booked it in to get a after market ecu and an electronic boost controller (getting done on 17th). i was wondering what the next upgrade would be best to make more power out of my car.

stock r34 gtt (neo) is 145kw at the wheels, which is 194bhp so your result is right on the money.

I wouldn't trust that site if my life depended on it.

1. The information was all ripped from these forums about 4 years ago.

2. Its out of date, never updated

The best info is always found by searching these forums, rather than some muppet who claimed limited info from these forums as his own.

IMO that site should be shut down as there is so much wrong with it that it gives me a headache to read

ANYWAY - 206kw = 280hp

184bhp is about 134rwkw... so that sounds exactly right give or take a 10kw difference for dyno's etc

So realistically there is nothing devastating about it at all, its a factory car making pretty much exactly the factory HP/KW.

To be honest you need a full exhaust etc before a ECU/Tune... You wont get anywhere near the gains with JUST a ECU/Tune as you would if you put a decent flowing exhaust on there

don't be upset dude, as others have said. if the car is stock (completely) then thats RIGHT on the money on what your car should be making. Look at getting an exhaust and an EBC running around 10psi and you'll be making about 160rwkw maybe less depending on the dyno.

First question, no, that's wrong.

Second question, there are threads on this, what exhaust system are your running? And are you running a decent cat converter?

Yes, people often go the ECU + more boost + exhaust system and either a pod filter or airbox panel filter upgrade + good tune and get a nice gain :D

Hey, maybe im a bit confused, i thougth that the GT-T's came out with 206kw(flywheel) as well as the GTR? Ok maybe not 206 but it should still have considerably more then the R33 (187).

So on paper given a high 20% D/T loss, a healthy GTT should see around 160-170rwkw stock form am I not correct in thinking that? 184hp is a mere 137rwkw.

When was it serviced last?

Could you post up your dyno sheet by any chance?

yeah here is dyno sheet

If a mechanic advised you to spend money on an ecu and boost controller, before exhaust and even a better quality air filter (in the airbox), you should go else where; It seems he is just interested in making the most money from you and doesn't care about your interests.

Fair enough he may have gotten confused about the power figures etc, but any good mechanic would recommend upgrading the factory exhaust system first.

guys, seriously now, a "non-happy dyno" on a stock car will go anywhere from 120-140rwkw depending on the health of the car and other factors. as al said too, you're mechanic is probably saying that to you to squeeze $$ out of you. oh dude your car is really low on power you need this this and this now to make it go hard.

first things first. get an exhaust, a cai, and maybe a hi-flow cat. you will notice a very nice gain alone just with those mods.

if your going to be boosting it id be putting a larger intercooler at the same time.....

also the r34 gtt is alittle heavier than the r33 gtst so the extra engine power is almost cancled out so not much differnece in actual real life power between stock r33 and stock r34...

      Is r33 gtr steering wheel the same as the gtst?

      They need to get a grip. R32 GTRs got as low as AU$8-10K at one point here.

      R32 GTST - 600KW+ RB28/CD009 Build

      Structured text and other high level PLC programing languages are not allowable in Functional Safety. They are very difficult to audit. My PLC stuff is almost exclusively oriented towards Burner Management Systems which are a particularly pernicious form of Safety Instrumented System, when implemented in an SPLC. Even the part of the code written to work in the non-safety logic part of the PLC, like with a Siemens S7-1500 series, still needs to be treated as if it was safety code, with access restrictions, code fingreprints and the like. And Allen Bradley can go EABODs. They ae full of shit. They have this whole lie going on where they say if you use a ControlLogix controller and its IO, and then just duplicate the IOs (ie, run in series or parallel depending on type, to try to make it "fail safe") and "use these programming styles and place these restrictions on what you do" that you can achieve SIL2. What a load of crap. They just get away with it because no-one in the US seems to understand the first thing about Functional Safety and carries on as if all they have to do is buy only SIL2 rated equipment and hey presto, it's a SIL2 system. Idiots. /rant

      Magnetic Drain Plug Snapped in Half

      By MBS206 · Posted

      If you're really considering leaving it, a great question to ask is, is the magnet going to stick to the sump? The answer to the above is the same answer towards if I'd have any level of comfort leaving it... Personally, based on the cost of a motor if the magnet were to cause damage, I'd be fishing it out either way. Use the methods in here. It fit in through the plug hole, it'll come out.   PS, get a small actuatable claw for a bore scope. OR if you know a vet, they have really cool controllable scopes with hooks on the end. Supposedly they're like playing a video game. Ask if they can acquire you one of their scopes... Engine oil after all is just a different type of lube right? Will only make it easier on the next dog or cat...

      All other (Boolean) logic functions though, are just built on those blocks above. Which does give you a lot of functionality in logic. It is basing that on using thresholds with analogue signals like GTS alluded to.   Not having things like timers will make it less useful for some of the ramp up logic you'd want, and again, on Haltecs capacity specifically, I'm not across anymore what you can / can't do with different tables.   I'm assuming, with your logic you want to implement, not only do you want your timing safeties, you're wanting to be able to derive the duty cycle for your solenoid, to maintain I'm assuming 175PSi? Or are you using a standalone WMI controller to maintain the DC correct, and you just want the Haltech working out which fuelling maps you should be on?
