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

dont old planes have pistons all round?

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.

      I thought that might be the case, thats what I'll start saving for. Thanks for the info

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
