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...

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)

yeah more than i have to spend though:( only have a budget of 5K at this stage

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

... 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

      S1 rb25/s14 starting problem

      By Duncan · Posted

      Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
