Pulling this neo motor apart for someone atm and its got bent valves on cyln 3, the valve guides have snapped and ones missing all together, I have a feeling it broke up and went through the valve and into the chamber because theres damage on the head and piston.

see pics.. is it fixable?

also for lolz.. see the dodgy repair somone has done to the CAS bracket... wtf

lol CAS bracket repairs like that are more common than you think, I've seen and heard of plenty going around. So dodge lol.

As far as the head goes it's repairable. I don't think the seat will be overly damaged, if at all. New guides, new valves, rock and roll.

The chamber is fine.

Mine had more det damage than that on the quench pads. I skimmed the head till it hit the pads to make up for it.


Just blend the pads so they don't have any hard edges.

yeah its a DET head, DE is different.

as for what happened.. im pretty sure the broken cas bracket and subsequent dodgy repairs lead to valves being bent and snapping the valve guides. not sure how it only bent intake valves on one cyln tho

Wasn't the belt coming loose or something?

Although when that happens, usually related to a tensioner wasn't replaced properly/at all, it'll take a few more valves with it or even snap them completely. Certainly got away with it pretty well

how are the det heads and de heads different?

    • Is it alright to top up with just another green coolant?
    • thanks GTSboy. My confusion at the moment is i am trying to locate the ignition, ECU battery power and the ECU negative The closest thing i can find is the for the S15 on Page 8 of the Wiring Specialties web page https://drive.google.com/file/d/0B9F33_M_GgENQnZ6STMxVmVNd1E/view?resourcekey=0-eZ4nNRwRoqa1qvKlWWHm8A I cannot find the same diagram for the R33 RB25DET Series 2 dash plug pin out.... Do you know what the Pins? or know where i can find the same pinout diagram for the RB dash plug? Thanks for the advice on the box... i like a 6 speed so might be on the lookout or the box now.. a topic of discussion for another post...
    • Will have a look at that. I cant see any leaks 
    • Put another overflow bottle (ie, a 1.25 coke bottle or similar) under the overflow hose and see if it is being pushed out there or if it is disappearing into the engine.
    • Staring on a stand is no issue. You just have to wire everything up, give it fuel and cross your fingers that the stand is robust enough. Arranging the inlet plumbing is often the hardest part, without any surrounding structure to hand some of it from. No need for coolant if you only want to run it for <1 minute. As to the gearbox - I think the little Aisin box is a bit stronger than the other small Nissan boxes that went behind SRs, but I wouldn't be too keen to test its limits with the torque of a boosted 25. I don't know if you can retain the box and the tailshaft. The box won't connect to the RB without an adapter of some sort, which is either a plate that will push the engine forward (which is not good for fitting it into the bay's available space) or push the box back, which messes with the box position and tailshaft length - OR - cut and shut work on the bellhousing, which is a long way from "least modification". I'd be buying a new 370Z 6 speed or similar, doing what has to be done to that to make it fit RB (ie, cut and shut bellhousing) and the requisite tailshaft custom/mods.
