speedo won't work as i'm pretty sure the r32 speedo is cable driven while the later models are electronic. could probably overcome this by using the r34 gearbox, but will then have issues with the fact that the r34 sends the signal through the ecu and the r32 does it differently.

not sure about tacho

People forget one thing about the RB20.

Wind up the boost + basic mods till something goes pop and then jst drop another one in.

Their pretty cheap these days

so are rb25s and they last longer

NA section always provides a good lol :/:)

I beleive that it isn't legal to put a motor from an older car into a newer one??

not certain though.

Certainly isn't allowed in SA; Not sure about other states tho ... I'd be contacting appropriate transport authorities and checking - but I'd doubt it'd be allowed (given ADRs, emissions, etc)

only difference is that to then go faster the rb20 is easier to extract more power out of. but that said, i'd go a rb25 because they will put out with the very basic mods (exhaust, cooler and a bit more boost) than what an rb20 will with more mods.

There was someone on this forum with an orange R34 4 Door with an SR20DET. The idea was that the SR20's could pull a lot of power with a smaller (2litre) engine which also reduced the weight and improved weight distribution.

I'm not sure how this compares to an RB20DET? One thing for sure is that you'll save on injectors, sparks, coilpacks etc.. with there only being 4 instead of 6.

If you were going to go to the effort of an engine swap, at leaste do it once do it right and put a larger displacement RB25 engine in, or why not turbocharge the RB25DE NEO?

Thanks all for the input :) running on rb20de neo is really a pain in the arse ... underpower! was thinking of TC it but have thought of throwing in a rb20det from a r32 will be much easy. seems like it not a great idea comparing to TC my rb20de neo. i am looking for those bolt-on kit for my r34 now but was advised to get parts from r33 will be cheaper ...

Dude all i can say is research research research... I researched for over a year about what my better options were, and only now am i going through with the engine swap in my car, basically turning it into a GTT. It is one hell of a pain in the ass, easiest option by far would be to sell and buy a GTT. Reasons I didnt do that are because the body of my car is in very good condition, and i have spent over $10000 in upgrading the brakes, suspension, body kit, paint, everything. So really the only thing i was missing was the GTT engine, gearbox and drivetrain; decided that if i was to start again and buy a stock GTT, i would be back to square one, where the only thing i liked about the car would be the engine, etc. and i would have to spend money everywhere else again. Also I am just very attached to my car :D

There is a thread on here about how to turbocharge your NA, have a read of that and also speak to N-DAWG and 666Dan as they have been through it themselves and gave me some good advice about it.

Before you go looking for more power though, have you upgraded your brakes and suspension? Because if you stinge on those things, your power upgrade will not be very much fun at all...

If you mod your car it'll probably be illegal and even if it isn't, you can still be defected for it and engineer's can still be reluctant to put their name on it (especially if the owner is clever enough to 'opt' for an RB20). I believe there's actually some legal problem with putting a smaller engine into a car too (at least in the sensible state of Vic).

I have been told by guys who've swapped RB20s into Silvias that it's the worst decision they ever made and when their budgets get back up to strength they usually reverse the swap or sell and buy another. A Silvia for sale with an RB20 is like a girl with the Jack. SR20s are capable of much more power, much more durable, better on fuel if that's on your list and more reliable.

But, you've got an R34, there's a reason Nissan dropped the RB20 when they thought of the RB25; and all your engine mounting points, gearbox mounts, driveline, aircon, other electrics etc. I would assume would mostly match up with an RB25DET. I think you'll find money you spend on the RB25DET will be way less than the cost difference or time consumption if you diy of putting in an RB20. If you just wanna be unique, try a 2JZ (Supra) or something?

      I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.

      This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.

      J50 clock date suddenly reset to January 1

      By suko · Posted

      The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.

      Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
