Easily. The RB30 block causes the head to be situated very high compared to the stock 26, pm cubes and ask him about how much clearance he actually has (he reckons its not a lot)... cant run a strut brace with a 26/30 unfortunately

-D

ah cheers!

i knew the 30 block was taller, only assumed a touch though.

30mm is a lot in an engine bay for clearance issues. Then think that everything like exhaust dumps etc need to be re-fabricated to suit the taller block height. It's all one big task

thats why if you go the kakimoto route you get to keep all your dumps and stuff

as with strut brace Cubes kept the over the top plenum and inlet pipe work if you go front facing plenum you can have a strut brace

thats Gold Carl

I've heard good things about N1 blocks being bored out to 2960cc with forged pistons - no need to have clearance issues if you don't need to!

ps: those cat things crack me up :laugh:

Cubes had a R32 GTS-t didn't he? It harder to fit the RWD RB2x/30 because of the over the rocker cover intake manifold which reduces clearance even further. The GTR's have more clearance but there are still bonnet problems, also with the GTR's you can't drop the engine like with the RWD's because your dropping the drive shafts as well.

There's 38mm difference in the blocks.

yeah cubes also tilted the engine too from memory and dropped it a little lower in the engine mounts cant be done as your reason on GTS4 , GTR

    • 32010-AA520 - R34 RB25DET manual transmission, you can buy this new. You'll need a pull to push type clutch converter (to use R33 clutch kits), or buy pull-type clutch (R34 clutch).   R33 part number if you're lazy: 32010-21U00     Applies: RB25DET.MT.F5; Notes: FS5R30A
    • Hi All, Ive recently pulled my head in and gotten started on my 2year long project for my R32 RB25 swap, I went into it head high and confident it was an easy swap and plug and play wiring. I was wrong. The engine is a S1 RB25 and I'm running RB25 ECU And loom. I got the swap done a few weeks ago and have been working on the car on my time off, however i cannot get the engine to run, at first the engine would crank however the fuel pump would not run,  i dove a little deeper and realised that i would need to connect the wires from the RB25 Body Loom and the RB20 Body loom. went through the ECU pinout and followed the wires from the Body looms one by one to find what was needed to start the car. Now I have rewired the RB25 loom with the old R32 Body loom attached, however i am still having issues starting the car, now the pump works but still wont fire.  The car has spark but looks very weak, however I'm suspect that its not getting any fuel. I have read a few posts related to the "Main plug" near the air intake however cannot find any information on what wiring to hook up to where.  If anyone has done this swap, or has any knowledge at all on RB25's into 32 i would really appreciate your comment regarding this, im really keen to get this car finished.  Thanks in advance
