Hi guys,

I've been given a RB20DET AWD Engine and I've got a RB25 GTS-4 AWD Gearbox, was wondering if these will bolt up or if any modifications need to be made, can I still use my heavy duty clutch from my current engine on the RB20?

Also looking around it is hard to find an RB20 Forward Facing Plenum, I've heard the Exhaust side of the engine is the same as RB25 but intake side isn't, is this correct? Can anyone suggest where I can get a RB20 Forward Facing Plenum? Also will an RB25 Fuel Rail/Injectors bolt on to the RB20 Plenum or would they need to match an RB20 as well?

Thanks in advance guys

Dan

Quite a bit of work - you'll have to modify the sump for 2wd and the g/box to get rid of the transfer case. Can you not sell them (sell the g/box in the Stagea forum!) and just buy an RB25DET?

Thanks Simon - any idea about the actual engine mounts are they the same between Rb20/25?

Why would I change it to 2wd?

I've been given the engine thats the only reason I'm looking into parts needed and if its going to be a pain in the ass, otherwise I'm still looking at an RB25DET Neo motor from a Stagea which I know would be the better option but $1500 extra which I could spend elsewhere cause I'm not after massive power, looking around 250kws only.

Becasue you haven't said you have an awd car - you are listed as having a GTS.

      Definitely do-able haha. I will give it a try if the fuel pump hanger does not solve the issue. Just need to find some quiet time in the area, Malta is like a big city and I live right next to the main hospital so it is very busy during the day. I'll be installing it in about 2 weeks, found a garage that is pretty knowledgeable and has the necessary tools. This garage has worked on multiple builds, even for competitions. They even asked me to stay with, so I should be fine.

      Just to add, I found the r32 gtr ecu the most forgiving, the r33 one would get the shits.

      For what it’s worth I drove my gtr for over a decade with gt-ss as a true daily after I pulled off the -5s, I had it engineered and went with stock ecu etc.  never skipped a beat.    I would only worry if you can’t get good fuel all the time in a tropical paradise

      Engine model

      By Bwagz · Posted

      I bought an engine from a friend of a friend many years ago, it was sold to me as a RB25det Neo.    recently I started pulling it apart and noticed that the intake manifold was pretty different from others that I had seen on RB engines so did a bit of research and found that it was a non turbo manifold. So I’m sceptical now that it is a NEO DET and just thinking it’s a NEO DE (it does have a turbo strapped to it currently).    can you identify the engine model from the numbers on the block?
