R33 S2 Gearbox Removal

Trying to change out a clutch on a mates S2 R33 and we were trying to do it without removing the engine. We have got it all sorted, but there doesn't seem to be enough clearance in the tunnel to get the box far enough back to get it out of the car.

I have had this happen to me once before (on a Mk1 Escort) but that was fixed with the judicious use of a dent puller applied to the tunnel and I would rather avoid that if possible.

Is there a trick to this? We have tried turning the box about 45 degrees in either direction and jacking the front of the engine up to increase the available angle with no success. We have got the box far enough out to completely stuff the friction plate alignment so I can't put it back on to the motor to lift the two out together so any advice would be hugely appreciated.

Thanks for that. I assume this a problem you have seen before? How far up do you recommend we push the engine? (we are using a block of wood under the crankshaft snout ATM)

Is this going to make getting the box back in as hard as I am imagining? Or am I just being a pessimist?

I never thought I'd say this but I am starting to mourn for my days of working on Trevmobiles...

I know the RB25 box is a fair bit bigger than my RB20 box but here we go.. was easy to remove but a pain in the ass to put the new box in. Had to undo the exhaust to let the back of the engine to sit lower and turn the box nearly 90 deg to get it back in, can't remember which way >_<

make sure u undo the engine mounts and unbolt the exhaust from the cat makes life a shit load easier i found out the hard way... make sure you jack the car up as high as u can.. Getting the thing back in is tricky as well i had to kick my box back in haha (only cause i didn’t think to loosen the engine mounts and exhaust till the last min >_< )

Are you doing this jacked up in a driveway or something? had my car up on the hoist which might make it a bit easier.. I've only ever changed the gearbox in my old HZ Prem. in the driveway.

he prob is,

it took me 2 hole days from 8am to about 10pm at night in the rain with 2 mates helping out to get mine out take your time it will come out... i had to drop mine onto a spare tire just make sure u put it in a good position so it does not hit the ground maybe use 2 tires... it is a heavy prick as well so if u have enough room make sure u have 2 people holding onto it.. (way bigger then a R32 box)

btw I got mine out with out undoing the exhaust or engine mounts which should drop it down another inch allowing it to slide out more… give it a twist as well so the bell housing/ starter motor can clear the firewall.

r33 eddy - no offence to you personally, but that's the biggest bodge job i've heard of. there is no need to unbolt the engine mounts - waste of time.

you do have to unbolt the exhaust hanger off the gearbox, and take it off the front pipe - more space.

you don't have to jack the engine much - tiny bit.

Dropping the gearbox down? We're not in the ghetto or something. Get a big trolley jack and use that to control the box down, and use it to lift it back up again?

      I mean it's probably likely that people overestimate their skills in dialling in a setup and noticing the changes. I had SK shocks and springs, and added heavier springs and got them revalved by Sydney Shocks to suit based upon what I told them I wanted the car to handle like. I got back a completely different feeling set of shocks, which probably (?) feel great on track but holy hell are they rough on tram tracks and the like. Truth be told I doubt I'd be any faster or slower with either setup, or camber/castor combination. I also had whiteline eccentric castor bushes up front of my R34. I removed them and put in poly non-adjustable ones to soothe my OCD (nobody ever set the castor the same side to side, and it'd be near impossible to do) and be happy the wheel is centered in the well now for clearance reasons. Yes I wanted it to move 1mm 'back' :p I've effectively set my castor back to stock, negating all the benefits of that which is supposedly massive. I can't tell any difference steering the car.

      R32 GTR EV? The leaf of the Godzilla's!

      You reckon? I have to disagree. Notwithstanding that at some point we may all be forced to do this to our cars if we want to keep driving them, there is absolutely nothing about an electric-converted-previously-IC-car that is ever good. EVs that are built by OEMs on platforms that were originally IC already suck, let alone the shitty outcomes that result from doing it as a retro to something that was actually built as an IC car. This is because the platform really needs to be designed to house the battery in a useful place (ie, down as low as possible) and the motors are properly located relative to the wheels that they have to drive. Converted platforms already suck at this. But when you try to shove sufficient battery capacity into a previously IC car, you can't put it down on/in the floor, because that space doesn't exist. You can't find enough space where the fuel tank used to be (if it is an inboard fuel tank) and you don't want to hang it out behind the rear axle line if you had a rear fuel tank. And there's not enough space in the tunnel if you still want to use it for anything remotely like what it was originally used for. The engine bay is too big for a motor, and you'd really prefer that the motor for the rear wheels wasn't in the front engine bay anyway. And there's not enough room where the diff was for a proper man-sized E motor. And then.... there is the complete lack of soul and emotion that is provided by EVs. There are some cracking restomods out there. Like the Alfaholics GTA thingo. But it is petrol powered. Look at the alternative EV version of a GTA restomod by Totem. it is jaw droppingly beautiful. But by all reports is is objectively awful to drive, despite having 600 HP or something, simply because there is nothing there. It sounds like a sewing machine or a leaf blower. It should scream and wail and make the hairs on your neck stand up. Oh, and it's 1500 bloody kg in a car that was <900kg when new. GTRs are heavy enough as it is without pushing them up to 2tonnes worth of pork.

      don't know anyone in this thread, but i just found it, read the entire thing in a few hours, realized greg is still posting progress, and just have to say, this is awesome. it looks awesome. 100% right about the Uras kit making it a pain to get on hoists...have the same kit on my 34 and it takes six 2x4s and race ramps to do it without taking parts off. this reminds me exactly of this thread. https://grassrootsmotorsports.com/forum/build-projects-and-project-cars/r63-amg-the-unicorn-of-my-destruction/110824/page8/
