hey guys just see what you guys think of this

my cousin has a r34 gt-t manual ( stock ) other then a pod filter and cat back

and one of my mates just bought one with a exaust, pod and been boosted to 10psi

but it was a auto and now converted to a manaul but its a shit load slower!!!! even though its running more boost..

how is this possibal are the auto's de tunned?

any feed back is good feed back

Yes it's me, and yes that R34 is slow haha.

I just can't wait till I get a turbo-back exhaust fitted and the engine/turbo should rev quicker and be much more responsive.

But yes, i would also like to know what other people think. Are the automatic R34 GT-T Skyline's de-tuned from factory just like the automatic S15 200sx/Silvia's are?

Cheers for any help :ninja:

De-tuned? No

The Auto has a different ratio diff to the manual, That would play a part. Also engine condition, service history, type of fuel being used, condition of fuel pump etc etc

but to play a big enough part that the one that had the conversion was running a singel stage boost controler and significantly slower?

Jace, I honestly reckon it is due to my car having the standard exhaust. Once I get the turbo-back exhaust, power fc, electronic boost controller and a tune i should be looking around the 270-280rwhp mark.

you wont get 270-280 with just those mods. The stock R34 turbo wont boost about 13psi with 14 maxing its efficiency range. I saw about 250rwhp with all those mods. I have a full turbo back apexi 80mm dump with 100mm exhaust.

Hrrm.. Maybe you just got a 34 in bad condition or something wrong with it? Mines an auto converted to manual and its perfectly fine.. havent done heaps to it, pod, zorst from the turbo back, lightened flywheel an hd clutch.. Nothing special and its got a good boot to it running stock boost.

Have you had it serviced? does it do anything odd? ie: idle funny, backfire etc??

Hope you work out what it is mate, maybe its been boosted and not tuned so afr are rooted?

Good luck buddy hope you work out what it is.

Also - be warned that if you need to upgrade the clutch (like i just have) the japs usually convert with an r33 gearbox so you would need a different clutch to a 34 clutch (one is pulltype and the other is push type).

Could cause you some drama if you get the wrong one first because I've been told its not easy to determine until you drop the gearbox out.

Nah nothing funny about it.

I need to service it (plugs, oil, filters, throttle body clea, etc) but nothing unusual.

I know i can get close to 280rwhp with the usual mods (Z32afm, boost controller, exhaust, intake, fmic, computer, tuned correctly), as my old skyline was making 265rwhp with those mods :)

Yeah it does backfire, only because I unbolted the cat from the rest of the exhaust and have been driving around like that (i got bored of a dead quiet exhaust and did this till i get my proper exhaust haha)

    • Save yourself the headache of an alarm. Immobilizer on the signal side of the main EFI relays so it won't start is good enough. DIY killswitch is the same thing except instead of a nice passive system you need to remember to switch it on and off.
    • Yeah, the advent of canbus was supposed to cut down on wiring weight, then some bright marketing wonk says "oh, look at all these wonderful tech gadgets we can cram in here now that we have this wonderous technology" and some arsehole safety legislator says "oh, look at all the wonderful surveillance and tracking gadgets we can cram in here now that we have this wonderous technology" and some dipshit young engineer who has grown up thinking that an extra 500000 lines of code is not a problem because storage is cheap these days says "oh look at all this wonderful shit I can do to one up those dipshit arsholes over at VW" and the Karens of the world all go "oh look at all these fancy things I can do on my screen (so long as I am not driving on a bumpy road wherein touch screens immediately become the single most stupid shit idea ever shoveled into a car) and my 19 zone airconditioning keeps my sweaty fat folds a bit less damp and the windows close themselves because I'm too fat and lazy to wind them up for myself and these reversing sensors would have been great if I'd paid attention to them instead of smashing them on the bollard while I was reversing and staring fixedly forward that day I went to pick up little Charlize from ballet" and the sweaty mongoloids who say "oh this wonderful collision avoidance technology with these 45 excellent radar antennae scattered across the front of my car mean I can tailgate like a methed up tradie at full speed with no fear because the car and the 35 airbags will protect me if it all goes wrong" ...... </shallistopranting?>
    • There's a post from a member (can't recall who), went down the path of a twin scroll G30-660 and it's doing over 300kW+ AND comes on about the same as a high flow RB25DET turbo. Have your cake and eat it too in this case. TBH, if I had a 2nd chance of building my car again (i.e. someone gave me what I wanted for my shit box, but the deal was I had to re-build another R33 and keep the change) I would just pop in a stock NEO motor (with new seals, rod bearings, ARP studs, head gasket, sump, Nitto pump), get a smaller twin scroll turbo, modify the stock low mount (keep the divider in place), and make a solid 300kW on 98RON and call it a day. 
    • It's all the sound deadening, and extra shit piled into them, plus all the extra (even though it's thinner) material for crumple zones. I can't fathom in modern cars why they need canbus to the headlights, and why the headlights must be vin coded on some cars to the ECU, BCM, and security module! Especially when they claim it's for security, yet, the canbus at the headlights let's thieves steal the car in minutes, so even more cars are being stolen! The Mercedes Sprinter 907 vans. They're a huge van, but a "basic" van. Yet they have that many canbus networks, plus two Lin networks, AND an Ethernet network. Logging a single network alone of 8 byte data frames, and they will generate a 20mb log file in 5 minutes. That's one network, and I can't remember the exact amount, but there's over 10 full CAN2.0B networks in them. I'm not a fan of modern cars, oddly, more and more I hate DBW, and all the bullshittery the cars try and interfere with. But all that bullshittery adds weight, plus crazy regulations on crumple zones, plus, ever picked a modern seat up, half of them have like 4 electric motors in them and will weigh 30+kg each. Then all the motors for things like adjustable steering columns blah blah blah. And did I mention the sound deadening so you can even hear an ambulance right behind you even if you 7.2surround sound is off?
    • Ah ok, yeah it should be flat, I believe the r34 battery tray has these 3 bumps in them they makes it line up and everything is flat, don't see how it would tilt if everything is secured.
