Bad luck Mona. Will be interested to know if it's oil or fuel related.

Hows the oil in the sump look? Lots of golden flecks? May have just been a rod let go too. How does that look on the gudgeon (piston) end where it snapped off?Looks beaten on the lower part of the rod.

My advice for a daily driver though is RB25 with the right work and the right turbo. 26 is too lazy low in the revs and if you have a grabby clutch you will get some spin trying to get the thing going in the wet with RWD.

All the best on the new one and please post whatever you want in my thread below.

boost - 1bar

well confirm if the fuel pump is still working on not.. as far as i know she still is!!

Geoff - will do!! and yeah... losts of scrap metal and water droplets :w00t: Couldn't see the piston end.. only had a top view... so can't tell you what it looks like!

it's not that complex moonie..

look for the user CUBES. in his signature, he has a PDF file which is like a DIY rb30det guide.

go from there..

if you are going to be paying someone to fix your motor for you, might as well get them to do the 30 for ya.

probably cost less.

considering bottom end costs about $100

if you want forged goodies, then both bottom ends will cost the same.

small mod to the vvt oil line

small mod to the engine mounds and your done.

so to speak

Moanie who is having a look at the engine? like Geoff said it seems like the piston failed at the gudgeon pin which is pretty unusual? And we can't really tell if the rod broke as well.....and presumably when it all let go the piston mashed into the valves and head at eleventy billion miles per hour.

Normally pinging will blow out a ringland and you will loose a heap of compression before a rod or pin fails, so I'm wondering if there was some other cause?

moooooona

you had what, 250rwkw before?

on the same boost, on a STOCK (read: stock pistons, rods, crank, gasket etc) RB30 bottom end, you would have that power or more, with loads more torque earlier in the rev range, and would be more reliable.

If your head is ok, it would be the cheapest option for you.

if the head is gonesky as well, then you need to look at it a few more ways.

stock second hand rb25det from wreckers?

stock rb30 bottom end, with stock rb26 head with new rings and bearings?

I've seen rb26 heads complete with manifold, injectors and so on for about $2K

Justinfox is selling a pair of 2530's for $1K (one has s blown seal or something but thye were both built by GCG using HKS cartridge or something)

All bolted together you'd have some spastic amounts of power which a little girl like you could ever want.. :)

Not sure what sort of $$$'s you are looking at spending here or can afford to spend but think it all through and do the math before making a choice.

Finally... if you ever need someone to point and laugh at your misfortune, you know where to find me. well for the next 3 weeks anyway

      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. Rb25det s1 walbro255 fuel pump nismo fpr holset hx35 turbo fmic 3" exhaust freddy intake manifold q45tb q45 maf   Re: s1 RB25det flooding at start up Fri Apr 12, 2013 5:07 am No, I didn't. 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.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      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

      By GTSBoy · Posted

      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.
