Dang, that's shit. 7-8 years is good, but still shit. :(

I'm super keen to see where this goes tho, theres some good banter in here already and I'm in for the ride.

Could always swap it out for a BMW N54. Duncan love these. 

I could just buy a BMW M2 comp instead and be done with. I know @Dose Pipe Sutututu will approve.

100%

I regret building mine, I always seem to make wrong financial & illogical decisions in my life.

Actually, good idea.

To paraphrase the 200B joke, the N54 has 1 less design flaw than the N55

And the head, looks like 2 intake valves got bent and a bit of a dent on the edge of the chamber. Should be repairable if I can get my hands on a couple of valves.

Rest of the engine components looked good. Definitely less cross hatching in the cylinders than last time it was open. Surprisingly, from what I could see of the crank through the vacant no. 5 the journal didn't look that bad, there's more damage on the counterweight. The crank will be scrap but I expected to see more significant damage.

On the hunt for 2 intake valves so I can get the head repaired, if anyone knows anyone with a couple to spare, please let me know.

I wonder if the turbo letting go the first time was a warning sign the motor was going to let go.

As in bits of motor came out and knocked the turbine.

Hopefully @GTSBoy's RB hoarder mate has things for you!

If not, I know of a guy with a built RB25DET NEO that's keen to sell his motor, also comes with a complete running R33 with A/C, subwoofer, new window tint, added sound deadening, etc. Lol.

Possibly but don't think it's related as it looks like the rod definitely let go before any bit of piston did, turbo survived this time. How about a straight swap? I know what I've got..

Why would he buy that specific RB25DET NEO when he can buy the solution to constantly exploding RB25DET Neos... with similar extras?

Sorry to see that mate, hope the repair goes well, are you  DIYing it? 


 

Thanks Dan. Engine building an RB is not something I think I can do to the level required. So the only DIY will be limited to installing an engine or properly repaired head on a good block.

Yeah that's not going to buff out. How is they bore where the rod failed, any grooves you can catch with a fingernail?

Surprisingly other than the viewing window, the bore looks great. There is one gouge that you can feel. Im pretty sure I created that when trying to get the piston out with a crow bar😂

You know any suppliers that sell it by the bucket? 

A rather extreme form of block grouting?

And ironically - yes. We have an epoxy supplier that I buy buckets of different sorts of epoxies from, for various purposes. You kinda have to open a vein though.

Get it machined and I imagine you could do the work to rebuild it yourself if you wanted to, but I'm saying that after having invested a lot of hours and a few bucks in in learning and having just started a fresh build that didn't blow up (just pisses out oil from new front and rear mains lololol). 

Send it to NCR and I'll build it for you cheap as but you get zero warranty lol

I’m amazed at how well that head has come out of it. Worst case is open the chamber up and build a off tap rb30 for it 

Me too, rb25/30 would be nice but then would have to upgrade everything are it. Turbo, injectors etc. are all too small.

I still would buy that RB25DE NEO for cheap(?) and keep it spare OR use it :) 

 

I am seriously considering this route, trying to arrange to go have a look at this particular motor.

The problem with this scenario is that the bulk of the $ is in the machining and parts. Wouldn't be saving all that much by assembling it but the chance of me messing it up would be too great. 

I'll send you the windowed block to practice on, 😂

Options so far in the pipeline

Cheap rb25de neo

Disassembled RB25DET NEO minus head, good condition. Reasonable $ but apparently pending. He's going to let me know if the buyer doesn't turn up. Idea here was to rebuild with correct forged pistons and put my head on it. Would be a good fresh motor. It's unlikely though.

Good running RB25DET. Prices unreasonable so far.

The joke was Dose was attempting to sell his complete car, and I joined in too.

My gut feeling is to tell you to actually go RB30 if you get the head cleaned up. Never turn down an upgrade opportunity when something breaks... it makes it more bearable 😛

    • I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
