Looking to purchase a Evo IV !

Would like some general views on the car, before putting the wife down as a deposit !

Cheers if you can help ?

Ive heard the engines a little more fragile than the rest of the series but i think the iv has easily the nicest rear spoiler and are rarer than the later evo's if you wanna stand out

hiya Dan evo 4's are quality cars my mate owns an evo 4 gsr and has had no problems with it at ALL. i own an evo 5 and his evo is just as fast as my evo ( our cars both have their share of wee trick bits though e.g dump valve, mod'd ecu, performace exhaust etc ) so if i was you i would certainly take the chance and buy it

hi!

The Evo4 is the first evolution model that is using the AYC, and Brembo brakes only comes in the later Evolution 5 model and up. Engine internals are the same as Evo 5 although the turbo wheel is different although remaining in the TD05 Shell.
The 4G63 power plant was remained as with the previous models, but it underwent extensive modifications. Introduced was the use of a high-speed cam and lighter pistons.

The EVO IV was refined in a way in which it reduced turbo lag by minimizing the gas flow interference within the exhaust manifold. In came a twin-scroll turbocharger which had improved supercharging performance, generating more torque in the low and medium range rpms. The EVO IV also featured a newer and redefined intake manifold which was straighter.

The introduction of a secondary air induction system improved turbo on-off response by feeding pressurized air above the turbine and reducing negative pressure, thereby keeping turbine speed from dropping under deceleration.


Hope that helps...
