To combat oil starvation issues, I am using:
- Ishihara-Johnson Teflon Crank Scraper
- ATI Damper pulley kit
- Boundary Engineering Chromoly Racer Oil Pump Assembly, 1 shim
- Maruha Racing Oil Pan Baffle

Yes, from the early days.
I run the BEGI racer version, slightly modified. And this time, it will be:
- no tstat, but gutted tstat at the back of the head
- no heater core circuit

So you picked up ~10 rwhp from all that? At least I remembered 235-ish last time we dynoed together?

Two things
1) Topic is reliability and I've added little to no performance enhancements. Same old turbo. The 99 vs 94 engine is what makes a difference here.
2) It's not just 10hp (it's 20 really), it's about the area under the graph:
