I've just bought a brand new Turbonetics T76 (with the F1 turbine wheel) instead of getting my T72 repaired. Hopefully the higher surge line on the T76 compressor map won't cause any issues. I've also just refreshed my engine and have done Brian Crower 1mm oversize valves and have Crower 10.3/10.5mm and a ported head cams so the head should flow enough to not be an issue. I'm running in the car over the next few weeks then we will see what power it can make. I suspect my Bosch 044 will run out of flow at around 430rwkw (previously had 415rwkw at 21psi) so that will be the next item I will need to upgrade.
