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.

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.

      Not going to pretend I didn't do a bit of junky work this time around, but mostly due to the fact that some things I am not willing to spend days fixing right now, like wiring. I try to do most things properly the first time around.

      Regardless of neglect or incompetence, fixing either is tedious and annoying. Most of the neglect on my car is definitely rust. I hope I can at least pass inspections later on and they won't fail the car due to slightly corroded hardlines. I was generous with rust converter and wax and it looks ok, most lines in the rear are hard to see properly anyways.  Definitely will test them though to make sure they don't rupture under pressure, in that case the car isn't going anywhere this year.
