I'm about to do a engine/gearbox in and out job on a R32 Gts-t.

Q1. Can the engine and gearbox come out TOGETHER as one unit?

Q2. Has anyone tried dropping the both out THROUGH THE BOTTOM still

connected to crossmember and suspension?

If you have how does it compare with out through the top?

Thanks

I did a R32 GTS4 engine swap (RB20DET -> RB25DET), removing the engine out the top. It is an absolute pig of a job. There is very little room to get at anything. I swear, IF I do it again, it all comes out the bottom.

In particular, I had problems removing / refitting the starter motor, and I couldn't get one of the top gearbox bolts back in. And I had to remove the alternator, and both engine mounts to get it out.

If you have a hoist, then it is probably easier to bring the engine and gearbox as one unit out from underneath (that's the reverse of how it was assembled in the first place)

i took out the rb20 box in the car, the the motor out from the top.

Replaced it with a rb31det, with a rb25det gearbox bolted on, inlet manifold, exhaust manifoild, turbo, starter all attached.....in through the top using a hydraulic 2t crane :D

Was a piece of piss...took about an hour and a half of friggin aound to get it to sit on the mounts though.

Ther crane only goes so far in, so you have to get someone in the bay to lift box over radiator support. Once over jump out, then have two people under, or a trolley on wheels to slide the box back as you lower the lot.

Oh yer.. When you get as far as you can go over the top, the engine is still over the radiator support. To clear it, you have to lower the crane while pushing the motor and box forward at the same time....kind of down and forward together...

Easy as once its in, just had to plug it all up and your away......

Thanks blind elk.  By the sounds of it you took out motor and left gearbox in car?

I have got access to a hoist.

Yes, left the box in the car, otherwise need to figure out how to re-connect and bleed ATTESSA hydraulics. But I would do the "engine and box out the bottom" next time (if there is a next time).

From Bl4cK32's description, sounds like its a no-brainer to take it out the bottom.

i dont think you can take it out the bottom if you left the box in. Normally you undo the 4? bolts holding in the engine cross member, check for anything else holding it in and lower it.

BUT you have to pull the input shaft out the back of the crank, so you may get a catch 22....undo the lot and see if the lot (motor and x member) slides forward enough to clear the shaft...i dunno cos i dropped the lot in through the top :D

Thanks guys

We are going to try taking the whole lot out from the bottom - box and all on AFL grand final weekend (my teams out so I don't give a s@#^ who wins)

If there is anyone eles out there who have done it this way...I'll like input.

I read an old zoom article where JMS removed the moter/g/box in a 33 gtr from the bottom. It sounded easy with a hoist - if you don't want scratches I'd say it'd be the way to go. I've done it a lot of times from the top and always said I'd like to do it from the bottom if I had a hoist...!

Just pulled my motor out again. i was going to go the bottom route but. after pulling the crossmember and steering rack off there are 4 pipes for the p/steering/ 4ws, i didn't wanna take these off so i went out the top again. took the G/box off first. took less than an hour, easiest part. jack the front of the motor up a bit to get to the top g/box bolts with a long extension. rattle gun and swivel helps too.

with the top starter motor bolt. i used several extensions, 14mm socket. . connect them together until the ratchet is above the alternator and then undo or tighten from there. easy.

We take the GB off first (unbolt cross-member to Access top of bell housing) and motor out through the top.

On way in we assemble lot first and go in from the top with a trolly jack under the diff.

Hope this helps next time.. Good luck at Baksy tomorrow.

I recently did mine.

It all came out the top.

I ended up pulling off the inlet & exhaust while the engine was in the the car.

I then dropped the gearbox cross-member and guided the box out while my old man worked the block and tackle.. Was a piece of piss.

Took 10mins all up from dropping the gearbox cross-member.

Putting the motor/gearbox back in was just as easy except this time it had everything fitted.

Exhaust manifold/inlet/plenum/starter etc.

Lining up the engine mounts was easy providing some one is under the car lifting up the gearbox. Once the gearbox is lined up so does the engine mounts.

I just got my RB25DET (series 2) and I was hoping you could help me with some questions.

My Skyline is non turbo so it will be a big step with the RB25.

Now then, my first question is about the gearbox mounts, I hear they aren't the same and I will also have problems with the speedo meter. What do you know about this? Can I use the Xmember of the R33 ??

The second is about the harness, everyone that has ever swapped an engine told me that the harness is the most difficult part of the swap. Do you have the diagram of the R32 and the R33 (still can't find it for the R32) and some pointers on how this is done??

Hope to get a reply from you soon

I have pulled RB engines and gearboxes (non 4wd) out the top so many times I have lost count. I have an engine crane only but almost always will pull the gearbox out with the engine because it is much quicker than removing the gearbox whilst in the car (if the engine has to come out as well). Disconnect the power steering pump and AC compressor and pull to one side. Disconnect the exhaust dump pipe, heater hoses, and wiring to the starter, alternator and gearbox. Remove the engine wiring by disconnecting sensors and then secure above firewall. Remove radiator and intake piping, vacuum hoses as required. Remove tailshaft and disconnect speedo drive.

You can then remove the single engine mount nut for each side by removing from underneath the cross member. With a jack underneath the gearbox, remove the 4 cross member retaining bolts. With the engine crane positioned over the engine slightly forwards of the engine mid length position, you can load the engine crane and drop the gearbox partially. Note, you will need a reasonable angle on the engine if you are to get the gearbox bellhousing over the radiator support. Remember to add a plug to the back of the gearbox to prevent loss of fluid.

It usually takes me about 10-15mins to remove and install an engine and gearbox once everything has been removed/disconnected. I usually will have 1 or 2 people present to ensure nothing grabs when the engine is coming out or going back in.

Some food for thought.

Cheers

    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
