R34 Gtr Powertrain Into R32 Gtr

[derk]

hey everyone, not sure if this is the right section to post in or not.. but here goes

i currently have an R32 gtr, and i want to swap in the engine, getrag 6spd tranny, rear diff, ect into my r32 gtr, i will be getting a complete R34 front cut with tranny/ complete rear subframe etc

now, i know the attesa in the R32 is hydraulic, and the R34's are electronic.. so how would i go about this? will everything be pretty much straight bolt on?

anyone else done this before?

anything else i need to know about other than the attesa?

any help/info/points in the right direction are greatly appreciated!

Gearbox goes straight in

But you will need

34 gearbox with mount

34 gtr clutch,

modify the shaft, ( i think its joining the 34 front half to the rear half of the 32's tail shaft... i cant remember what we did with mine)

clutch slave obviously

and all attessa is hydraulic.. on the gearbox side of things anyway..

no need to change diff.

If you fit the r34 engine, then you need to fit the r34 diff, as it has a vastly different ratio(4.11 vs 3.5 i think)

[Scooby]

correct, unless you want a circuit/sprint car you'll find the ratios quite short.

[Duncan]

its the hicas that was hydraulic vs electric. and I assume you are ditching that.

BTW what are you expecting to gain with the swap?

[arep3]

id also like to know what your after with the swap.

do you mean gearbox instead of engine?

i do agree with doing the swap, the 34 box is nice and streetable, and also has very short ratios which i dont have a problem with.

i was lucky and scored a nismo imput shaft with mine, which is almost twice as thick as standard

i'm still running the 32 ratios i believe. tho may have been changed before.

[Duncan]

well front ratio is in the sump, so unless he changes the sump he gets the r34 diff.

im just looking to build a 500hp ish gtr street car, i like the getrag 6spd, and the helical lsd that the r34's come wtih, and i have connections that can get me an r34 front cut for cheap, so i might aswell haha.

that way i dont have to fix the R32 oil pump drive on the crank.

the motor will be stripped and built from the ground up, so really i guess im just after hte getrag and the hlsd haha, everything else can be done with the r32 motor i guess.

yes i think thats what i mixed it up with, the hicas, ill be ditching the hicas while im at it.

Shit, i forgotten about the diff in the sump, i'll be installing a 34 engine soon. what would be best to put in? or just use my diff from the current 32?

I think the getrag would be perfect if your not paying much! I paid alot when i done mine but i'm not complaining, i love it for the street the ratios are quick and it can take a bit of abuse..

i've also got a 34n1 motor on its way so we're doing pretty similar things.

if you want a carbon shaft for 1400 be sure to check it the group buy. need a few more people

just swap the hole sump its dead easy

you'd be better at just doin the gearbox and diff swaps if you really want the getrag and diff ratios.. as for the r32 oil pump drive on the crank issue.. just buy a new r33 gtr crank.. there only 1000bux for a brand new crank.. much cheaper than buying r34 front cut and goin thru all that conversion shit...
