Hi guys any advice appreciated!

Bought car with 170000k's, FMIC'd, cheap turbo, bigger radiator, nistune'd ecu, splitfires, swaybars, 2 way diff etc, drove car for 6months without issue, eventually got a small noise which got worse with time and heat, eventually 'blew up' cruising on highway with abnormally high oil temp, massive internal knocking sort of noise from engine, key off & coast to stop, tow truck, home to cry. Engine will start but it sounds that bad you dont even want to put your head near the engine bay. I believe i've spun a bearing in a rod but am unsure?

This car was not babied and I am not suprised something has broken, just after the best way to go about fixing it.

I've purchased an RB25DE NEO for $1350 from an engine import shop in Brisbane in late January (business name withheld atm), I still have the receipt, and have not removed engine from crate it was delivered on.

I asked for an RB25DET NEO and was sent an RB25DE NEO. I only found out today as i had a mate take delivery. They have a 7 day return policy (it took 4 days to get delivered!) and will not take the engine back as he keeps telling me I asked for a non turbo'd engine. This is a complete lie. All he would do is give me $1250 store credit towards a turbo'd RB25DET NEO (for $3000).

What do you guys suggest i do? Is it possible to unbolt sump off both engines and swap crank, rods and pistons after machining? Or should i fix my engine? What parts exactly will need machining? Whats a natro 25 worth from a private seller?

ALL REPLIES GREATLY APPRECIATED! :)

Is it bad form to post on old topics?

Just wanted to get back to sau and say i've successfully put all my turbo gear on the DE and it works really well. Timing had to be pulled and fuel added via nistune due to a knock but otherwise i'm really happy with how its ended up!

I do however still have a small intermitant problem. Randomly sometimes when I stop and idle I get oil smoke out of exhaust, sometimes its a fair bit too and can be fairly embarrassing! Decel in gear seems to make this worse?however sometimes i can compression brake down massive hill and come to a stop and the exhaust is perfectly clear!

Intake side cam cover is the DE one. Is the PCV system different on the DE from the DET? The turbo is new so don't tell me its leaking out the exhaust side!

Thanks for any input guys!

      Rb26 iron block limit

      I was under the impression the reason why OEMs are going with solutions like relatively thin "right-sized" cylinder walls with technologies like PTWA and open deck is because they care a lot about whatever marginal knock margin benefits they get from that vs the structural rigidity benefits of a closed deck block and thicker cylinder walls. I also see some weird stuff like plastic inserts in the water jacket around the cylinders to try and equalize cylinder wall temperatures. re: the PRP blocks and heads at the end of the day it's hard to know what is and isn't going to work there, just have to see what the initial buyers say about it.

      Which is why I didn't mention that hardness testing, and specifically mentioned the bore and deck thickness testing. Yeah, not really. The bore temperature will be a lot more even around the top half inch or so, where the material distribution is dominated by the deck, and which is the only place where the bore surface temperature heating any gas in the cylinder is likely to have any effect on detonation. Think about it. Another inch or so down the bore, you might have a hotter spot. The gas there might get a bit hotter, then the piston rises squeezes that gas away from there at high speed and mixes it with other gas from nearby. Instant dilution of the problem. I'd be surprised if it was an issue at any time other than in racing engines or OEM dev engines being run at the ragged edge of tuning. Say what now?

      https://dsportmag.com/the-tech/education/engine-tech-material-hardness-testing/ The PRP testing on block hardness I'm not sure how much it actually can be trusted. The thinner cylinder walls on RBs is a bit of a problem vs 2JZ but it really depends on the design goal. Siamesed cylinder bores like a 2JZ cause uneven cylinder wall temps too, which means a bit of distortion induced by that + the hotspot can affect knock margin. Something that actually gives me a bit of pause with the PRP block, whether super thick cylinder walls are going to keep it from being drop-in compatible on an otherwise OEM rebuild.

      Yeah very valid point. I am waiting for one of the other tuners to come back from vacation so he can help me a bit when the cat is installed again. In the meantime I am going to finish up my polishing and ceramic coating that I have started myself.    N45 Dr Beasley product is highly recommended for a paint primer / polisher. Using this EXO Gtechniq also for the ceramic but next time might use the light serum before hand also. Looks great.

      Running rich in conditions where it shouldn't probably won't do great things for catalytic converter lifespan. I would fix that sooner than later.
