Rb25- Mating the Engine to Transmission?

[Dil-Dog]

So my mechanic and i was wondering if its possible to put back the rb25 engine in my R34 Skyline with the transmission still in the car... Asking because to drop the transmission is alot of extra work and we wanna know if they can be mated together when they are both in the car. I cant find any example or video on any forum or on youtube... only seeing guys who mate them out the car and THEN put it back in all at once. If anyone has done this before please let us know! Thanks

Yes definitely doable

Its easier that way i reckon, than pulling both out.

Wait  so is the engine out and box still in now?

Install is reverse of removal.

lol just like the workshop manual says.

the only things worth mentioning are dropping the rear of the gearbox by lowering (but not removing) the gearbox cross member bolts, will make getting to the top bolts much easier (either from above, or by using a set of long extensions while standing at the rear of the gearbox), and of course the engine has to be on the exact sample angle as the gearbox/input shaft when you get to the last couple of cm.

BTW I hope the mechanic is mates rates if they needed to get you to ask this...

Thanks for the advice guys, and yes the gear box is still in the car and the engine is ready to go back in.... we were wondering how hard it was (if possible) to mate the gear box and engine in this pariticular case rb25 in an r34 . But from what i am understanding from you guys is that yes it is possible @Duncan @Ben C34

Just lift it and poke it in. Same as almost every RWD in-line engined car sine the 1920s.

Okay guys... thank you all very much we were just concerned as SOMTIMES it can  be impossible depending on the car and its space available in the engine bay. Still learning everyday its also my first time and my first build ??
