A bit odd looking, but amount of machine time that would go into that is impressive. Berrilium-copper valve seats, thats an interesting choice of material.

If it took 13months to develop from scratch, it shows you how quickly a car manufacturer could churn an engine out with all the experience they have.

Just seems pointless to me, unless you are looking at it from a concept point of view.

It would need lots of counter balances by the look of it and they would just add weight and suck power.

Whats wrong with just making a v8 or v10?

i do like the idea of the engine, its compact, and would fit small cars nicely (ones with a short front end) but dont know about the balancing (i'm sure it could be worked out) and the manifolding. the exhaust/intake on that just seems wierd to me.... and exhaust manifold running up over the engine doesnt excite me....

that said, would be good to see one in an MX5 lol

whose gonne be first to make an X engine?

edit - forget the X, i actualyl thought about it and its not practical. lubing it would be a b1tch

i like when people think out of the square good luck to the bloke who had it built i would love to see it in action .it is easier to knock someone than to have a go at it yaself ..i love it for all you younger kiddies you should have heard the fuss whn mazda made to 10a in the r100 or when suzuki made a rotery bike .for all we know this prototype maybe the next gen donks in our cars

it makes peak power at 10700 rpm, and peak torque at 7200, this would be a dog on the street... well thats my guess without actuall seing a dyno graph

Actually, i think quite the opposite, the further apart the peak torque is to the peak power, the more tractable it is, imagine it would probably pull quite well from 4500-10500, thats a nice wide torque band.

I think he was wondering how you oiled a piston that was upside down.

      Possible swap on R34 RB20DE NEO?

      By GTSBoy · Posted

      If the RB29 box in the car is a push clutch, then yes, you will need to deal with the pull clutch on the turbo box. You either buy a pull clutch and don't use the old one, or you do the things needed to convert the turbo box's clutch arrangement over to push. Which is a bit of a f**karound. "Making" a custom tailshaft is the easy part. But you will need to source the front clip yoke - the bit that goes into the output of the gearbox. These are not as easy to find. They are out there, but they don't grow on trees the way that they used to.

      Turn signal wiring question

      By GTSBoy · Posted

      Indicator bulbs are way too bright to use as a "corner marker" (we call them parking lights too). Sure. Go ahead and do it. But realise that you wil need to come up with all your own wiring to do it, as no-one will have a standard howto worked out for Skylines. It's just a matter of abandoning everything that Nissan have done and starting from scratch. You'd probably be better off retrofitting tailght/brakelight globe bases into the front indicator housings and using the taillight circuit for your corner marker and the brake light as the indicator. You'd need to work out how to kill the marker circuit while the indicator is flashing, otherwise it won't flash on-off, just bright-less bright.

      Possible swap on R34 RB20DE NEO?

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..
