Neo Internals In 33 Block

Hi all..

Just wondering if I can use my neo pistons and rods in an r33 block with an r33 crank?? Not sure of series 1 or 2 if that helps..

My neo crankshaft has an overly flogged out keyway and my block has a crack from a water jacket to the head stud.. also has been decked twice so wouldn't bother repairing the crack and decking again..

Got the r33 bottem end free so want to make use of it if I can..

Any help would be greatly appreciated..

Cheers

r34 pistons wont fit as they have a different combustion chamber to the r33 heads, so in theory you can fit all of the above, however you need a NEO head if using NEO pistons, or r33gtt/gtr pistons to use the r33 head

He is planning on using everything,including the head, from the neo.

And will r34 pistons actually not fit with a non neo head? I know the comp will raise a fair bit, but they would still fit right?

Exactly..

My current complete neo engine has a crack in the block and a flogged out keyway in the crank..

Got a complete r33 block for free so will jist swap over rods and pistons..

Of course will do rings, bearrings etc etc...

i know the r33 pistons with neo head is a no go, but the r34 pistons with r33 head i havent tried that. most possibly raise the compression a bit, also not sure how much they will poke over the block at TDC....

      Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.

      Oil pan for RB25DET NEO Stagea "version"

      meh, it was a good video, clear about the issue and how he dealt with it. A bit heavy on the RTV and very brave to put an RB in anything without rebuilding it first, but otherwise I thought it was good Dose, I'm not sure that having the pickup forward is a big issue; yes of course the oil could shift under brakes but the sump should never be empty enough for that to be a problem (unless you also have a higher volume oil pump, and that oil can't return from the head to the sump quickly enough)

      I can donate $100 to your upgrade fund. So long as you can donate the IC7 my way....

      I'd love a Haltech ECU, and Haltech 10 dash. Was having a chat with Rob and Andy @ Haltech when Rob put one in his MR2. First one I'm kind of interested in too, as you can dim it RIGHT down. Andy was saying bright dashes is one of his peeves too!
