Hey all,

I know it's been said many times 'if you want a manual, buy it from the factory', but I was wondering if anyone here has experience with a manual conversion on an R34 gtt? I'm after all the details and if possible, prices/specific workshps (I'm located in St Lucia, Brisbane and currently head to SR Motorsport at Kippa-Ring).

What are my options? Can I throw in an R33 box? How much would I be looking at for a second-hand Getrag box out of the GTR? I'm more than happy to shop in Japan (I know a bit of the lingo) so if anyone could give me some direction I'd be most appreciative.

Cheers

Ok, so no replies...

Anyway, I've found the following for $3500:

box -- master cylinder -- wiring harness -- pedal box -- clutch + flywheel --- driveshaft -- dash meter panel

Does this sound reasonable? Is there much chance to resell the auto box to an R32/33 owner?

hey. I'm interested in converting my Gtt to a manual too.

but it seem that no one has done it befor, not to a R34 anyway.

I got a mag at home that have an article on 'how to convert a R33 or R32 auto to a manual'. not sure which one model :D but i will check and let you know.

good luck for now. I have try and still tying to look for infor on the net in regarding to mod to a R34 and there don't seem to be much.

have you got any information?

It only stands to follow that there about 1/50th the amount of r34 on the road compared to r33, etc and that not many people have done this conversion.

The price to convert any new car is much more more than the price of an old shitter, and finding the parts is a much more expensive proposition.

If $3500 is true, its a bargain price if it is all that is required on a 34. I've only done this on an R32, not an r34, but it sounds like they are all the bits you'll need..

And the gertrag box? thats a 4WD box, and would require extensive / expensive mods to convert that to a RWD platform. Again, possible if you have thousands to spend, but if not... .

I can confirm the price above is genuine, hence I'm going to come out about where I'd be (financially) if I'd bought a factory manual.

The reason I was so interested in the GTR box is because I read Getrag supplied the same box for the JZA80 Supra, however I'm thinking this is not the case...

Buy my stuff please. :D

Sorry my post is really off topic but I just realised.... Your car is pictured in Septembers High Performance Imports magazine, I am fairly new around these parts and got that magazine as I noticed the Top Secret V2 R34 on the cover.... You are famous dude!

Depending which state you are in, hopefully will meet you at one of the cruises or outings.

Hey guys. Really sorry I haven't noticed this thread until now.

I am the second person that I know of that has done the manual conversion. We both went to the same place but used different parts.

I conveniently had a manual R34 wreck so I took all the parts from there except the clutch line going from the master cylinder to the slave which some fcuker stole from me.

I would recommend using some R33 parts for 2 reasons. First is that they are more plentiful, second is that R33 GTST boxes use a push type clutch whereas the R34 GTT box uses a pull type clutch. The only reason this matters is because when looking at clutches to handle big power, push type are about half the price of pull type.

You can get an R33 GTST gearbox for about $1500 if you can find one. R34 GTT boxes are similar in price but even harder to find.

If you do use an R34 box you can use an R33 GTR clutch as they are pull type as well and fit up no problems. Also stronger.

New clutch master and slave cylinders are not too expensive.

Pedal assembly not too hard to find. Tailshaft must either come from a R34 manual (just the front half needed) or get a tailshaft specialist to make something up when you get a yoke from an R33.

Any RB flywheel will fit, need a flex plate but that's cheap. Flywheel bolts aren't too cheap. So try to get them with the flywheel. Get the flywheel machined as you will be using a new clutch no doubt.

So parts cost you are looking at I'd say anywhere between $2200 and $3500

Labour, both me and the other guy I know of got Greg from Autosport Engineering in Kirrawee (sydney) to do it for $1500 drive in drive out.

Umm what else... The interior parts are very hard to find. Might get better luck at Yahoo Japan auctions.

Mine is a 4 door and I used 2 door parts. Same wheelbase.

Dash and steering wheel are extra and hard to find. About $300 for a cluster and $200-300 for a steering wheel.

Clutch costs extra - depends how much power as to which one you get.

Stock ECU will work fine. PowerFC plugs straight in too.

Anything else?

if you are going to use r33 pedal assembly...the brake pedal assembly ..4 out of 5 bolts bolt onto the original holes..You can make up a new hole position with longer bolts. Shouldne be a problem..

the clutch pedal assembly fits perfect :D

ive just put the pedal assembly in and the clutch MC.

Just got your Auto tailshaft today from Stans workshop and hoping to mod it soon..but i got to find the second half of the shaft..the taishaft specialist needs it whole so they can balance it wen they swap over the yoke.

after that, it should be like a basic CLUTCH change..

LOL yeh i think i might have to, meaning car as to be off the road :woot: , but i need to get the exact measurments...If anyone has a r34 Auto and manual tailshafts lying side by side, can you me if the lengths are the same...from the top of the yoke to rear diff connection.

      Blue/grey smoke after idle

      Even with the piston at TDC there was room for it to drop, but I don't think it can drop fully into the cylinder, the problem you have is that you need something pushing against the valve to hold it up so you have enough room to put the new stem seal on and the spring etc.  I used compressed air only because putting rope in the cylinder seemed a bit risky to me, I know people have done it countless times before like this. Overall it's a pain in the ass job. Honestly you'd probably be better off taking the head off because the risk of dropping something in the engine and the finicky-ness of it all is very stressful. If you are going to attempt it though i 10000% recommend a 36050 valve spring/keeper tool. I had both the traditional lever type and after doing 1 cylinder it was absolute pain to get those valve keepers in place, even with 2 people. That 36050 is amazing, you do have to push hard to get them in place but it works perfectly almost every time. Back to my actual issue I think my engine is just tired and old and the rings have gone bad. The comp numbers (cold, no oil) were: Cyl 1 -129psi Cyl 2 - 133psi Cyl 3 - 138psi Cyl 4 - 137psi Cyl 5 - 157psi Cyl 6 - 142psi   Cylinder 5 and 6 having the most carbon on them.

      R33 Fuel Pump & Brakes after alarm swap

      Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?

      R33 Fuel Pump & Brakes after alarm swap

      Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.

      After market rear camber arm adjustment

      By GTSBoy · Posted

      Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.
