dry sump if you want but not really needed at that power

Agreed, no need for dry sump at that level IMO.

Do NOT use an Escort RS turbo manifold unless it's fitted WITHOUT drilling and tapping. Whether that be by using an adaptor plate, or welding on a new flange. They piss oil and work loose. Anyone that did an early ZT conversion this way knows it was shit after a little while (me included
)

there is talks of harmonics and this and that

depending on how you drive it will depend on how long it all lasts
nothing is forever lasting in this game to be honest
It's a combination of big power and revs. Revs alone do not kill them, they can rev past 8500rpm with no failures when N/A. It's the cylinder pressures which seem to wipe them out but a low power (300bhp ish) Zetec turbo will never see a pump failure IMO. No matter hopw hard it's driven. I gave mine DEATH for 2 years and 10,000 miles with no problems what so ever.

Proper double spring conversion or uprated singles?
