Right guys iv done a big end on my classic waggon and im now on the lookout for a new engine, and my question is if im gonna be replacing the engine what is the best engine to replace it with ? iv been told to buy a proper red top STI engine , but im unsure if an STI engine will run on my ej 20 wrx ecu , also will my original wiring loom fit ???

can someone please shed a bit of light on this subject for me ? my thoughts are..... if im gonna relace my engine i might aswell replace it with a half decent strong engine !!!


thanks guys

 

ive been told that a 2.5 is straight swap , and good low down torque with the ***** to take big power but not sure on gearbox . just dont get one from heathrow engines or one of thier many guises , shop around , gd luk

 

I would advice you to speak to David @ A.P.I before you go buying into a used engine mate.

 

No classic engines are strong as the rods are all the same and they are rubbish.

Spend the money on a rebuild.

 

hey guys just bought a 02 wrx and its misfiring a bit. was told its an exhaust sensor but its not the lamba sensor.. seemingly it gives trouble, as well as the lamba sensor. can anyone advise me as to wat sensor is possibly gone? its my first scooby so any help wud be greatly appreciated. cheers.

It could be a whole host of things- Plugs, leads, bad batch of fuel, dodgey injector etc. What mods are on the car? has it started doing this since the cold weather? what fuel do you use?

 

thanks ljf. shes standard wrx,, i was told that it was a sensor on d exhaust cud it be an oxygen sensor? im new to the scooby world, dont know too much about them. thanks for advice. i use unleaded fuel at d pumps. no it started before d cold weather.

 

You need to use super unleaded for a start, either tesco 99 or shell vpower. Anything else and the car is more than likely to run rough especially if the previous owner used a better fuel as the cars ecu has programmed it self for 99ron fuel.

 

ok will try and see how it goes. thanks mate.
