Block assembly time

With a complete Head & a Block ready to go - all we need to do is bring the two together - Thats the plan this Saturday

Ooooo spline oil drive, keen to see how this goes.

 

Looking good.

Heads-up...its time to put it all together!

A Cometic MLS head-gasket is sandwiched in-between & now its time to finish it off

All assembled & ready to go - a cheeky ASR extended sump has also been given a new coat of paint & will hold 6.5ltrs of oil

Next steps are:
- Transfer the Alternator, P/S pump, Aircon compressor from the old rb20 & fit the shiny gtx3071.
- Remove the rb20 & gearbox and make space for the Neo and Rb25 gearbox which will be popping inside.
- Work out the wiring

Still so much to do....

Up, Up & Away - time to rip out whats left of the rb20 engine & the gearbox...forklift style!

oooo ooo yummy, curious with your NEO what oil restrictors did you use? I've read the NEO block already has decent restrictors from factory and there's no need to run smaller.

Neo has single 1.3mm from memory (was like 3 years ago). I put single 1.2mm in my 25/30 Neo.

I read someone said 1.27mm which is pretty much 1.3mm.. I should be good then

Running OEM

No big news - been trawling through blurry wiring diagrams for the r32 to prepare for the massive job of wiring in the rb25 neo.
I have heard stories of people losing power-steering when doing such conversions and I tried to get to the bottom of this...

It looks like the HICAS ecu controls the electronic power-steering solenoid.
This solenoid is driven by Speed-input; at low-speed there is more power steering assistance & at high speed its reduced.

It looks like the HICAS ecu requires 3x inputs - Speed, Tachometer & Neutral.
As long as those 3x inputs are still supplied to the HICAS ecu, then there should be no issues with Power steering! (fingers-crossed)
Not sure where these 3 inputs splice under the dash or next to the ecu...will need to follow some wiring within the car & see where they lead..

 

Hope to create my hybrid r34/r32 engine-loom this weekend - some further reading is still required.

Still working on it - have managed to map each wire on the Neo F3 plug as well as the r32 body plugs. Will attempt this weekend on the hybrid loom.

For those playing at home, found an easy method to repin the Neo F3 plug here -
