That block needs a skim, and the piston has also suffered a bit too much heat, you may run into issues with it so replace it while it's out.

Agree. The piston is rocking and touching the head by the look of things..check for corresponding witness marks on the edge of the combustion chamber in the head.
If it is touching, its a possibility that it may have hurt the big end as well. Maybe not. I have had it where the piston will rock on the gudgeon pin and the bearing will be good.
If its already touching you may have to deck the piston tops as well to clear ..
Id also check piston to bore clearances while its undone..

Thanks for the help bk and you just spoilt my day with this news 🙁 lol

It might be cheaper to just go buy a RB25DET Neo , instead of rebuilding. 😉

This is not the same motor that i was going to get back then this is a completly diffrent motor and so far i did not spend a single cent on the rb yet as the sale of my sr motor coverd all my cost for my build so far :200sx_fuck-8:

You're forgetting a couple of basics like management, intercooler, exhaust, clutch and mapping to start with. This will get you to 340kw but won't get you reliability.

For that you can add water/meth, decent management (R20k +), proper mapping, oil cooler, oil drain modification, decent radiator with decent brand name fans, fatboy gearbox just to name a few. Not to mention the oil pump if you like visiting the rev limiter.

Those mounts look ample thick.. nice one.

Lekka project bud. Don`t let the naysayers discourage you about the rb , I bought a used Jap Neo auto from an R34 and have not looked back in over 50k km/s !! On Dicktator nogal !
Track days every month and more at Kyalami , it is also my daily driver. And it lives a hard life at 8000rpm on stock everything daily..

Last Sunday was a 120k hard trip in the company of two Supra`s ...she worked hard playing with the boys..

Lol yep 12mm thick took 5mins to powder coat and 1hour to cool down because of the thick steal.
