I’m pretty sure they’re all the same in ph2, with the exception of the cup o/s driveshaft, as it doesn’t have the bearing that attaches to the back of the block. Abs rings may be different on the 60mm spacing hub setup though, so more teeth. Certainly rings a bell, but can’t say with confidence.
I’m afraid those cam journals are fucked mate. There’s only one place that I know of that can machine the journals and it’s a good way to spend £500 easily.
The issue with cleaning them up is the increase in journal clearance, which can and does result in a reduction of oil pressure.
But, I...
It’s running a pms 7.25” clutch/flywheel combo now, but I’m pretty sure they’re the same 2.9kg weight that the one I had fitted was.
The engine was built for this kind of car/box combo too.
You’ll need to keep a close eye on oil temps too mate, as it’s in a completely different environment to what it was in when installed in my cup. Saenz steel rods will also be worth a consideration for longevity imo.
Great results there mate! I’m over the fuckin moon! Always knew it had more in the tank as it was mapped on what was the hottest day of the year at the time.
Couple of important things to note though! It’s not specced for 250bhp. It’ll need the steel crank, rods and solid lifters. Potentially...
That engine is, in my opinion, one of my finest achievements in terms of what I’ve built over the years mate. My cup was the culmination of what I’d learned over the years too. You’ve definitely done the engine justice with what you’ve built too mate. ?
You should see some more hp out of the old girl tomorrow mate, as it was mapped on the hottest day of the year at the time! Still sounds fuckin epic too!
The supertechs are still only a friction welded valve. It’s just higher up where they make the join when compared to the original Renault valves, so this could be a reason why they’ve failed.
What valve springs are you running? If the seat pressures are too high, that won’t help.
