Hey all .

Ok now so i finally decided to do the upgrade on my 32 and shove a 25 box in . So i got the box all mounted up and my short shifter all bolted in and selected everygear perfect. So i then put all the custom tailshaft and ect on then started it up to find i cant selct gear while cars running? Flywheel was remachined and clutch was only 10000kms old threw a new thrust bearing in and changed over slave . The fork isnt cracked and the slave does move the fork a good distance . Wtf is going on?

Without the engine running, you will always be able to select gears, even without using the clutch.

Simple answer is that the clutch isn't disengaging the engine from the gearbox. I suspect that the RB20 pressure plate isn't as tall as a RB25 plate, or the thrust bearing carrier is too short for the combo you have.

Can you determine how much free play you have at the fork?

You will probably have to remove the gearbox and do some measurements on the clutch assembly and the thrust bearing motion to determine what is (not) happening.

pressure plates should be the same, as aftermarket kits for these always say they will fit both rb20det or rb25det.

one of my mates had the exact same thing happen after we installed a new clutch and short shifter on his r32 about 5 years ago, i could be wrong but i think we just had to make an adjustment at the master cylinder.. or maybe the one behind the clutch pedal.. i cant remember which one exactly.

Adjust the rod at the top of the pedal..

The only time you will have serious issues is with multiplate clutches and getting the correct bearing/carrier size.

I'm going to assume you bled the system properly after changing slaves?

this might be silly, but did you check you had the clutch plate facing the right way?

would be difficult to bolt the pressure plate on if this was the case...

fly wheel bolts too long and touching the clutch plate ?? although u would think the flywheels would be similar in thickness

      Sorry, are coilovers ACTUALLY ILLEGAL in NSW? They aren't in Vic, as long as they retain 70% of stock travel and the car is above 100mm off the ground. Does NSW actually have a law making coilovers actually illegal? RWC/Blue Slip/Engineering people not knowing the actual f**king laws boils my blood. Demand them to point to the documentation that states a coilover is illegal. (it may exist in NSW )

      But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.
