Can any one shed any light on the possibility to put a double OHC head from the RB20DE on to the RB20E engine I currently have in my R33 GTS ??

What are the steps, cost, agro, etc. What would be my power increase?

Is it better to put in an RB25, or does the brake, tyres etc have to go up, as I think the RB20DE is not as big a leap as the RB25 would it too need new brakes etc?

Look forward to your thoughts.

Mark

I don't think you'd see much of a power increase in simply replacing an RB20E head with an RB20DE.

The R33's RB20E puts out 130PS@6,400rpm.

The R32's (I don't think the R33 series had an RB20DE) puts out 155PS @ 6,400rpm. Not much of an increase - especially given all the work involved (and you may have to swap over more than just the head)...

mate your probably better off just putting the 25de in it, brakes generally dont need to be upgraded nor do wheels or tyres and its a very easy swap, i dont know about the gearbox but if its nething like the rest of the nissan range it should bolt straight up so all u will need is engine loom and computer.

      I picked up my block and head last week and have been slowly assembling it since then. Pictures I took earlier this week. The rest of the auxiliaries are on now. I just have my intake manifold runners to tap for my WMI direct port setup before putting it back on. I should hopefully have the motor back in by this weekend.

      I couldn't agree more. As an owner of a built high HP skyline, I'd be a hypocrite to not buy a Hummer for the reasons you listed though haha.

      Stagea boot lid probs

      By soviet_merlin · Posted

      Is this the one? https://jpjdm.com/shop/index.php?id_product=2192&rewrite=nissan-stagea-c34-rear-boot-actuator-assembly-90550-0v000 Might be worth having a look at yahoo japan as well. Though it seems a bit odd. If the motor works itself, other than being noisy, then wouldn't it be more likely that it's an electrical issue somewhere else? And it being noisy does not seem as surprising if it has been chugging away for months

      Stagea boot lid probs

      By BCs300z · Posted

      I know this thread is quite old, but I found it, it helped me, but I also wanted to add my experience and troubleshooting finds to the chat for others. I have not been able to open the rear hatch of my 97 Stagea for several months. Figured it had just really sealed itself up over the winter and I would just get to it eventually. Well that day was yesterday. Some time ago, I noticed my battery was going flat all the time. It was frustrating. Then one quiet night in the garage, I could hear and ever so slight humming / grinding noise coming from the back of the car. It was like a really quiet popping sound or something like sand in a very low speed blender. I took off the panels in the back and noticed the noise coming from the auto close motor, so I unplugged it and the noise stopped. And the auto close was disabled. Well, fast forward to yesterday, I tried all the tricks with power and fuse and lock and unlock and I still could open the damn hatch. So I took off the panels from the inside and found the auto lock had engaged and was stuck in close position. When plugging and unplugging the fuse, I could hear the relay clicking. So I plugged the autoclose motor back in, and the damn thing let go. And immediately started making that grinding sound again. This time, instead of just unplugging the motor, I pulled the fuse, thus depowering the relay entirely. I don't have the autoclose feature now, but at least I can open the boot and not have my battery being sucked dead all the time. Not sure what caused the motor to latch when it was unplugged from the system, but I am pretty sure it won't cause any more problems now.  If anyone has a lead on a new motor, please let me know. It's a cool feature that I would like to get back.  Hope this helps.
