hey all, just wanted to ask any guys with 31's whats involved with putting a 20 or 25 into a 31? looking at a cheap 2l pintara wagon and rough cost for putting in a 20 or 25 with auto box.

rather put in this section for a quick reply. wondering if it could be done for around the 4K mark not including the car.

cheers

While I never swapped an engine in my old r31, I did have the misfortune to have the torque converter die... was cheaper to get it converted to manual, so naturally I did that. I think the parts were around $650 which came with the pedals and xfercase and clutch, and around $650 labor to fit.. this was back in 2003 so I don't know if the parts/labor would be cheaper/more expensive but I'm guessing if you got the engine + box you'd save a bit. That said the sr20 is probably cheaper and lighter and they give a decent amount of power and are pretty darn strong... also you'd have to factor in getting bigger brakes and getting it engineered. Dark.Sky put a rb25det into his 32 which originally had the rb20det and he had to do the above so you can guess that there is probably a little bit more involved for you...

think there is one for sale cheap with said mods already just need some finish work on car sales last week, around 3k mark if I remember right

cheers ill have a look.

gonna struggle doin that on a pintara matt

even tho the r31 platform is different, the trans tunnel on the manual is narrower

*edit* - read that you're goin to do it with an auto, thats not so bad

if its pintara, you'll just need skyline crossmember and some RB30 engine mounts (as the RB20 / RB25 ones push it too far forward and fan chews out the back of the radiator)

if you can find a skyline to put it into, piece of cake. swap RB30 engine mounts off and onto the new motor, run loom, think theres like 5 wires to get it to basically power up (theres a wiki section on R31SC with this info from memory). If you score an S3, the auto is the same as 20DET and 25DET auto boxes (4sp electronic auto)

If 5k total is your budget, I'd definately follow the above advice and just buy a 31 with all the bits and pieces (one with an rb30 will do) - Can probably get a Silhouette for that money in decent nick - good cars

nah has to be a wagon so silo is out. thinking maybe a patrol with the rb30 in and doing some mods on one of them

... or just get an R31 Wagon... the GXE's are pretty darn good as a platform to start with... I don't argue with your choice but the r31 platform is robust and is good for many applications - just need to be patient and get the right one

Good luck! I reckon for $5k you'll get an excellent skyline
