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....

      Could you modify this duct so instead it pushes the extra air through the radiator too and not down and out? For temps, I know it's not the greatest idea, but as a bit of a last resort, you could use a very intermittent misting spray onto the front of the coolers/rad. You don't want to be soaking them such that water is dripping off, but a small most on/off so that the water evaporates. That point of it constantly evaporating, rather than being soaked in water, will pull a LOT of heat out of the cooler. I'm literally thinking just the little mist sprayers for a garden from Bunnings. Being in a low humidity climate it will help even more! The other trick if you want to be ghetto is some shade cloth hung in the opening, and keep it wet. Pretty much now it's acting like an evap cooler on a house, but cooling the air you need to use to cool the radiator...   On a topic to think about too though, when air enters through the bumper, is it all nicely ducted from the edges of that opening back at a nice angle, or is it like most cars, and the edge of the opening just stops, and suddenly it's wayyy wider behind that? If it does the later, get it shrouded out at nice angles. When that opening changes too rapidly, it can actually cause a high pressure zone between the front bar and radiator, and limit air flow into that area, which means less air for cooling, as it effectively stalls the air, AND adds to drag...

      It doesn't look like there's a lot of options out there these days, and what's out there is performance oriented aftermarket stuff (with the GTR markup) I wonder if there are other cars with similar springs, after all its just a matter of length, diameter and stiffness. Alternatively, I did see coil spacers. Probably not the best option, but could be serviceable too.
