Esprit S2.2 over heat and underpower

[chung]

My 81 Esprit over heat badly at track, I great on the track but can run for more than 5 laps. Also it a bit on the hot side when drive hard on a hot (34C) sunny day. The car had recent engine services, new head gasket, new water pump, radiator clean and services. Did I need to up grade the fans or water pump (such as high flow electric pump). Last owner had lower the suspension, it may had make it worst with our climate. Any suggestion?

Get overtake on the straight by WRX and 911, any suggestion on getting more power out of the 2.2 engine. Looking for 100ps more

Thanks Adrian

But the S2 only weight 1000 Kg, so if i got another 100 ps more. Can eat WRX.
Know of any after market turbo, intercool and piston for S2.2?
Yes, the fan sometime turn on later. But even when on, it not cooling it back down to normal when going over 110mph.
