I've read lots of contrasting info on using solid steel exhaust valves on the 1.8T. I have forged rods, wossner pistons and an AET 380-04 hybrid making 398bhp. Due to low compression I'm having the bottom end freshened up with some new rings and a hone (or a less worn block if needed).
I later plan to add a GT3071R to get IRO 500bhp and more with nitrous as I use the van at drag racing events and will also be on track. What experiences have people had on here with solid steel (non coated) exhaust valves? I've got a few friend running 500bhp+ with solid exhaust valves without any issues, but another tuner in the UK has said solid valves are NA spec and can't handle the heat and I should go for inconel ones.
Does anyone here have any first hand experience. Whilst the bottom end is getting done it gives me a chance to consider switching valves if needed...? Anything else I should do?
Here's my 1.8T van for anyone interested.
