Yep, and when I fitted my 30, according to the RB30 twin cam pdf guide the RB30 would be too tall for the R33 engine bay but I had no height issues, bonnet closed fine with no rubbing.

I think he was just pricing up his options mate.

Possibly taking advice... I suggested an RB30 would be much cheaper and better! (BTW  an RB30 fitted under my Stagea bonnet even with a top mount with no lowering of engine mounts necessary).

Ok thanks guys

kiwiRS4T how did you go about 30 swapping your ride

The r34 mounts should work on the 30 in a 34

Stock internals, just rings bearings and con rod bolts. RB 25DET head retaining the VCT. Link ECU in the original case. Because the Stagea was AWD I got an R33 GTR gearbox but big box RB25 would be fine for 2wd. Stock manifolds would be fine for 500hp+

    • Hopefully it ends up being something manageable, like a hone, rather than a full bore—it would be a huge relief if it’s not as bad as it looks. Hang in there; these setbacks are annoying, but it sounds like you’re handling it as smartly as possible.
    • At the end of the day, it’s all about understanding the odds and being comfortable with the potential cost, whether it’s horsepower on a build or chips on a roulette table. And I have to say, the Laine example made me laugh—some people really do embrace that carefree, “roll and see” attitude!
    • Thanks MBS206, i got that PDF but got abit overhelm with all the connections and tracing of wires. I wasn't expecting to plug the dash harness anywhere. i was just going to use my electronics jumper wires to plug into the right pins like ECU power, ecu ground, ignition trigger etc... I do have a few ratchet straps locking it down tight. Fire extinguisher ready and only a small amount of fuel at a time, enough to submerge the pump.
    • Thanks GTSBoy, i will do abit more digging. I am missing a blue relay near the ECU connector... so i will chase that up in the next few days as well  
    • https://yariksteel.ru/manual/R33/Skyline_R33_elektroprovodka.pdf   Page 18 should be what you want for the Dash Cluster wiring. Though, you don't need the dash plugged in to get the motor running. What you want is power as how GTSBoy said. You need to power the ECU. Find in the above link the ECU pin outs (Verify them before just connecting them up from things written on the internet). Find anything needing power, give it power, find anything needing ground, give it ground. Then give the starter motor power through a big cable, and bridge the solenoid on the starter straight to power too.  ECU will be on, and when you give the starter power, it'll spin the starter motor, and it should start. I also hope you have a proper stand, and not just the engine sitting on some wood. You will want it bolted down properly.
