No worries - ceffies look so damn tough with a cage and every little thing that goes into my car to make it stiffer I end up loving. So I wish I had money to burn for a cage and a floor brace :D

I will post up on Saturday as to what the engineer says - I'll then be looking for borrow some wheels for blue slip *looks at CEF11E* :( so if that all goes down well CRUISE soon! :wassup:

Basket's car was landed with a rb25 :rant:

:rofl:

Was tuning my iebc.. noticed smoke coming out of it.. turned out something shorted - I think only 1 resistor is shot.. but that means the car is on LIMIT-LESS BOOST.

Anyways, coincidently I noticed water evaporating from my exhaust (some got in in the recent rain) so I decided to go for a quick spin to warm it up and evaporate it. So going along in 3rd coincidently it turns out I can't take it out of 3rd.

MY CARS GEARBOX/CLUTCH IS now officially cactus. LOL I got stuck in 3rd had to drive home in 3rd.. then as I got outside my house luckily it all let up and I could put it into reverse, then got stuck in 1st for ages as well.

Do engineers care about mechanical "worthiness" or just the safety aspects (ie structural/braking/etc)??

To remedy my situation I've got so far in the plan-

Exedy 6 puk ceramic $600

s14 gearbox $700

Installation $$

Either that or try my "mystery" gearbox I bought from a sr20de for $100... hmm choices choices :rofl: Does anyone know the best way to guess-timate the condition of a gearbox without opening it?

Either way everyone please wish me luck for tommorrow arvo for engineering :rofl:

Hi,

Have you checked the oil level / for oil leaks in the clutch master / slave cylinder? If you're having problems getting it into / out of gears it sounds like the clutch isn't disengaging properly. Just because you can't change gears it doesn't necessarily mean the g/box is stuffed.

As you have found out the hard way owning a midifyed car requires the owner to have good fault diagnosis skills or know a good well recommended workshop.

Good luck

:D

Thanks Glen,

I didn't realise there was oil in the clutch? Do you mean fluid? If so it's always full and looks nice.

When the car is on and the clutch pedal is not pressed it actually makes a grinding type noise.. when you push the clutch pedal in it goes away (as soon as you press it the sound slows down as if it was spinning down and then stops).

While I don't think that's the actual gearbox one thing that makes me think the gearbox is ALSO cactus is that 4th feels different to engage than all the other gears.

No there isn't oil in the clutch. If there is you will have a problem as oil in the clutch means leaky rear main oil seal or leaky gearbox input shaft seal. Oily clutches slip.

Instead of a old style cable actuated clutch most modern (all that I have seen) manual cars have a clutch master cylinder and slave cylinder. When you push the clutch pedal in the linkage connected to the pedal push a hydraulic cylinder (which is the clutch master cylinder).

The master cylinder then pushes oil (fluid) through a oil line (you can see this exiting the master cylinder if you have a look) which goes to the slave cylinder which is mounted on the gearbox. The slave cylinder has a piston in it which moves as you move your foot to dis-engage the clutch. So if there's a leak this symple hydraulic system then the clutch won't disengage properly/not at all making gearchanges hard.

By the sound of what you just said though it must be a gearbox problem. When take your foot off the clutch pedal the gearbox shafts will spin - when you push it in they slow down and stop allowing you to put the car into gear.

So that grinding noise you describe sounds like gearbox bearings.

If you buy a second hand g/box you won't know the condition of it - if it were me I'd pull the one I have apart first and inspect before getting another - it probably just needs bearings/seals etc.

If they are buggered and the shafts have too much end float the syncros won't work properly making gearchanges feel strange / very hard.

The r32 gearboxes have big nuts holding the shaft assembly together which get loose over time - not sure what g/box you have but dad and I pulled his r32 g/box apart the other day when replacing the clutch - we found the nuts loose so we tightened them up - now it feels like a new one - hardly any end float and second doesn't crunch.

Good luck

If you've got the box on the floor I'd suggest taking a look at it / getting someone to check it out before sticking it in the car.

In these photos you can see the nuts which hold 2 of the shafts assemblys together - just to give you an idea of what they look like. They have a soft metal edge which is peened over to stop it undoing - the photos aren't the best but might give you a bit of an idea.

Gday Glen - thanks very much for the photos.

I asked a mechanic if you could take it apart to look at it he said if you do that you may as well have it re-shimmed to put it back together... so.. is it ok to just take it apart to look inside and then put it back together, or will it fall apart on me ? :P

Cheers

CC - Mate i think the roll cage will be staying, but if i change my mind will let you know for sure!

Basket - Dude did you drop the RB25 into it, or did u get the car already with the RB25? Looking at dropping same engine in and i know prices for the engine but just wondering on costs for installing it all?  

Cheers

Deviat Mine came with the Rb25 in it already, I can imagine it'd be a bit of a costly operation to do in Aus, but the car does hall arse with the Rb25

Go the whole hog and build a cefzilla! Rb26! :wassup:

:kick:

Dave - Nice work on landing a Ceffie with a RB25 turbz in it!!! Mate i would love to drop the RB26 into it but cost difference bewteen the 25 & 26 is about $5000 so cant really justify it with current budget. May see what happens down the track thou...the RB25 isn't planned to go in for at least 6-12 months so maybe by then i can afford the donk RB26!!! :P

lol CC....i agree with the weight thing. That is the main reason why i am steering away from the RB26. Rb25 has great power capabilities with the weight advantage. Especially considering it will eventually become a track/dori pig :D

How'd all the engineering go with ur car mate??? All sweet?

If you're game it's not really hard to pull the g/box down to the stage in the photos. It would allow you to check for chunks of broken bits and also check those nuts for tightness. If anything it's really worth doing those two nuts ups as it made a lot of difference to dad's 32 g/box - just make sure you replace any bearings if they get damaged while using a puller or press.

To do this job you will have to access the box form the back - splitting the back of the box off. If you want to go further it'll be worth looking into shimming / new bearings.

There has been a bit of information going around on these forums about doing this - if you want more info just tell me.

Basically you have to :

At the rear of the box there's the bit where the gearstick goes in. The gearstick slots into a moving rod in here which selects the gears - you can see it from the top.

The rod has got a fitting (the gearstick fits into this) which has got a pin holding it in - the fitting has to come out before you can split the box.

Get a punch and carefully tap the pin out making sure you don't lose it in the box.

The fitting can come out now and you can undo the back section of the box.

Once all the bolts are out you can slide the rear outer section off the box. It will most likely take a bit of a gentle knock with a hammer to do this/gentle wedgeing with screwdrivers.

Once the outer casing is off you will see the gear selectors and rear of the shafts - just like in the photos. Straight away you'll be able to feel the nuts to see if they're loose.

In dad's box we made up a puller to pull the bearing off the 4th gear shaft - this is the long shaft which runs all the way to the rear of the box. The holding nut has a piece of metal which has been peened over - you'll have to bend it back if you want to tighten the nut up.

To tighten the nuts up we used a great big ring spanner ( you have to pull the bearing off to fit it on ) with a length of pipe over it, while I held the gearbox with a crowbar to stop it from turning. To stop the shafts from turning you'll have to lock the box into 2 gears at once - you do this by mucking around with the selectors.

That's about it - a bit of a rough outline - I'd say that just about every older skyline has loose nuts on the shafts - if I ever buy a 32 I'll check this if I've got the gearbox out.

We just used castrol mineral oil in the 32 - I just put synthetic in my r33 and reckon it has made no difference - not really worth 90 bucks for 4 litres. the stuff is so thin I can't see how it can do its job - it's nearly like water.

Cheers

Thanks Glen - sounds like a big job. After 3 months of fart-assing around I'm OVER it.

Funnily enough after my car go rego'ed i'd been driving around with it going from 1st to 2nd to 5th. Then after a couple of days 3rd and 4th came back as if nothing had ever gone wrong.. they actually weren't squishy and worked perfectly. Then today (a few days later) I rev'ved it out a little in 3rd and it doesn't want to come back out of 3rd. It will come partly out but taking the clutch pedal up then produces a god-aweful sound.. so I limped home and she's now stuck in 3rd.

*sigh* the plot thickens - I don't get why it would just work all of a sudden again... HMM!!

Dev - car is fully engineered, rego'ed but gearless :)

Cheers.

  • 2 months later...

MY CAR IS BACK ON THE ROAD!

Big up to BHDave who helped ... well.. he did most.. (95%) of the work so I should really say I helped him with the 5% (which was made up of handing him beers).

Thanks Dave! :P :P :D:) :) :D

gearbox - $100

clutch kit - $650

machined flywheel - $90

running car - priceless.

*happy dance*

Next issues to combat -

things that really worry me

- when going round corners enthusiastically (the lower end of enthusiastic) there is a thud or a creak from one of my steering components

- when turning at lower speeds (ie more strain on the steering) there is a thud or a creak from one of my steering components this may be the same or related to the one above.

- ecu tune need to get it tuned

- unknown injectors which are spraypainted to the nismo injector colour

things that make me angry

- took off the front pipe (that's hangin off the xforce split dump and leads into the cat) and even though it's 3" pipe all the way through they pushed the pipe together and welded a freakin 2" flange to the freakin pipe!!!!!

- the cannon still steps down to 2.5" (looking for new cheap muffler kakimoto or super dragger wanted!)

outstanding issues

- HID lights have the wrong focus point (gotta reinstall halogens and wait for H3 bulbs to come in..)

- IEBC still melting a resistor on me (gotta check it out with a multimeter to hunt down failed component)

- gotta get a grill for the front of my car

- gotta clean up the wiring

- metalic (brakes) rub every revolution from left rear or front wheel/rotor when going under 20kmh. Will replace/upgrade rotors with slotted ones next time I do brakes.

- squeeky brakes (r32 brake anti-squeel shims wanted!)

Can't wait for the long weekend! Thanks for everyones support during the last 6+ months and especially to:

ceffo, CEF-11E, DumHed, too_much_boost, BHDave (super hero!) :wassup:

AND a big up to everyone else who has given me random bits of information, support, parts, encouragement - this is every single one of you guys who are reading this! :grouphug:

(anyone I've forgotten it's not for lack of wanting it's for due to being young which results in bad memory heh heH) :headspin:

    • I am getting the same issue. Did you resolve it? I just got it after installing my new super coppermix and literally the same issue, new fork, new 18mm carrier, release bearing that came with the kit and replicated the exact same sound. 
    • If you like - I have the STL files so I can email em. There's a couple of gotchas (i.e the holes are not threaded so you might need/will need) to utilize some M3 melt-in threads for some of the points. However if you want to be super accurate, and are willing to remove your calipers and your SHOCKS it's a really good tool. You also might need to scale the part that measures the tyre width a bit wider. It defaults to a 7.5in tyre and I mean who is running that. Luckily with the magic of CAD this is very easy to rescale.
    • jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed
    • In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.
    • So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.
