Can a legacy engine be put into a impreza GL and use the ECU out of the impreza turbo?

Yes, the engine can be installed and bolted up. But-- use a turbo ECU with a turbo motor, and a normal ECU for a normal motor. There will be small differences between the cars regarding wire harness install, and small emission bits. Try to preserve as much of the original configuration on the car as possible-- that is what the ECU is expecting.

Yes you can you will need to get the non-turbo engine, non-t ECU and wire harness. The wire harness and ecu are diffrent between the t and the non t.

User Avatar

Yes it will make your life much easier to have the turbo ecu and harness. The turbo injectors have a resistor pack that the non-turbo engines do not use. So that would have to be manually wired in to use stock turbo injectors and ecu.

GST ECU is designed for turbo. you will have problems with ECU, but nothing that can't be resolved. It's a pain, but it can be done with minor motor mount mods.

You can't, it's done automatically by the ecu (engine management system)

User Avatar

It's not called a ecu it's called a PCM, On a non turbo it's located in the engine compartment behind the relay/fuse box.

Depends on how the ECU controls the turbo. If the ECU never lets the wastegate open, the turbo may overspin, which will damage it. On Audi/VW cars, a bad tune can cause an overlean condition, which melts the wastegate flapper door. This will cause your turbo to not boost.

Thanks to modern workshops, you can slap a turbo on pretty much anything. Just depends how deep your pockets are.. Go Pro, you'll need new exhaust headers and gaskets and rings and ecu... and more

User Avatar

yes it will but you will need to change the ECU - computer that runs the car / timing / fuel and air ratios. hope this helps :)

User Avatar

An ECU will require a proper tuning computer system. There a several available on the market. Then the car will require a DYNO test to allow the engine's turbo to be calibrated according to the response of the engine. This allows for the best fuel, air, and spark readings.

yes they are identical cars but you must do a complete swap (engine ECU as well) Kyle

The ECU isn't under the Dash. its under the passenger's feet. you must lift carpet to see protecting shield once removed you will see the ECU.i know because i own a 95 impreza and maintain it myself.

User Avatar

The short answer is yes, but A LOT of things have to be swapped out. ECU, sensors, dash gauges, complete exhaust system. Your talking about putting in some time and money to make sure everything involved with the turbo taken out and replaced.

hitachi variable vane on d22 running approx 15psi boost smaller turbo than d 40 which is a garrett and differnt ecu

User Avatar

When you turn the ignition on the CHECK ENGINE light will not light up at all.

User Avatar

In the passenger footwell fixed to the engine bulkhead. Lift the carpet from behind the glovebox and it is under a metal plate. ok

User Avatar

of course you can i mean the engine bay allow it but you need to install the ECU and engine/injectors/ecu arnes as well and if you ,re going to swap from automatic to manual you'll need the transmission shock too. good luck!

A turbo, an intercooler to coll the engine as turbos produce a lot of extra heat, an aftyermarket ecu as the fuel map of your car will have to be tuned, a dyno as your car will have to be tuned on a dyno.Installing a turbo in a naturally aspirated engine will greatly reduce engine life as the parts are not designed to run at such high temperatures and pressures.

User Avatar

The ECU is located underneath the wooden panel/ underneath the carpet on the passenger side, below the glovebox

User Avatar

check the crankshaft and/or camshaft position sensors, if they are not working the ECU will not "see" the engine turning, therefore no need to spark..

User Avatar

yes but you wil need good mechanical knowledge as you would need to do more than just remove the turbo and exhaust manifold the look up what is needed to turbo a car and thing of the process in reverse you wold need to remap the ECU remove turbo, the exaust piping would be changed to turn it in a non turbo and heaps or parts removed and replaced with non turbo parts i would not advise anyone to turn a turbo in to a non turbo as you can have presure issues with the engine and ECU remaping can be hit and miss

cone/mushroom airfiter with heat shield remove cat from exhaust, map ecu

User Avatar

No. Turbo engines have different components than the non turbo engines have. Even if the Ecu connector matched at the ecu, the components that the non turbo lacked will set off a check engine light, setting the computer into limp home mode. Not to mention turbos run a more aggressive fuel map and different timing due to lower compression Your best bet, look up Rallitek in google and go there and get a piggyback system designed for your make/model/engine

User Avatar

no, not at all. the newer VQ engines are rumored to fit, but you have a lot of work to do with the ECU and engine management when you do that. Best/easiest bet is to turbo that ka24de.

User Avatar

the 300zx is cheaper to buy a turbo'ed engine and all the managment that goes with it. otherwise you have to buy a differenct ecu and a turbo. modify the block and run oil breathers and all the running gear, intercoolers and sensors.
