Once more I have come to lap at the font of knowledge 🙇♂️
So, continuing to trawl most corners of the net in search of parts to build a complete RB26/30 from relative scratch. Have found a used cylinder head that has come off a 93 GTR.
Seller was upfront about history, which is always a good sign. Head came from a mates car, which was a tuned low mount double jobby putting out around 400hp? He was not sure on power. Engine suffered some sort of failure, but lost oil pressure. Said he took the head to have it looked at, and the guy (from head to head in clayton if that helps) said it needed work but could be saved. I'm going to get into contact with the repair shop who hopefully remembers the head in question. But otherwise will pay to have it looked at by a shop to get another appraisal of the head before paying for it, especially since its in Melbourne and I'm in Perth.
Now, I'm no mechanic but if the engine is starved of oil the parts that rub together get a bit sad. So I'm guessing the camshafts, the camshaft caps and the journals will need some machine work? Buttttttt, If I don't plan on using the OEM camshafts and plan to go for an aftermarket set, I would need to get the camshaft housings line bored anyhow? So it might not be that big of a deal? What are some of the other problems a cylinder head might suffer if it has run out of oil? 🤔
Included are photos for refrence.
