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!

      RB20DE NEO smallbox clutch.

      By Duncan · Posted

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      RB20DE NEO smallbox clutch.

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
