Dropping in a new engine

[McGoo]

OK Guys and gals,

My new engine should hopefully arrive tomorrow ( cheers to the Squirrel for putting me on to JapCars ).

I am assuming that the EJ20T engine which is arriving will have the same basic capabilities as my current unit.

However, I read that the power outputs of different MY cars can be different. Obviously with the Wagon/Saloon differing is due to the TD04/TD05 difference but should the block basically have the potential to generate the same power and it is left to the ECU to control Fuel etc ?

Did all the 1995 cars WRX/STi have the same base unit ?

Basically what I am asking is, if I shunt in a new ( replacement ) power unit, what should I have to do to get the same ( or more ) power as my current unit was able to give ( obv. before it gave up the ghost ).

I bow to the collective superior knowledge of the group. If anyone can help, much appreciated.

Cheers

Davie

PS - I should add that I am not carrying out the work myself, I just want to be sure that there are no gremlins to fall foul of when I get the car back. Oh and have the same, or more power.

The general power and smoothness will come from the TD05 turbo and the Z4 ECU that your car has just now

If it is a different turbo on it to the TD05 that is on yours then fit the 05 and it will run the same

1995 was the point which STI set up thier own production line so prior to 95 the STI and WRX block were the same.

After the new engine is fitted, limit the boost to 0.5 bar for the first couple of hundred miles.

Grant cheers again,

Q. How do I limit the boost ?

Also, where is the ECU ? Is it beside the drivers footwell on the right hand side ?

Thanks in advance

ECU is in the passenger side footwell behind the kickplate

To limit the boost to 0.5bar, run a length of pipe straight from the output nipple of the turbo straight to the actuator. This will prevent the car going any higher than 0.5 bar

Engine arrived yesterday but appears to have come from a Legacy or something else.

It has a TD04 Turbo and what looks like a FlyWheel from an Automatic.

Apart from the changes to the FlyWheel and Turbo, is the basic block capable of the same output as was standard in my 95 WRX or are there any differences on the inside that determine a lower BHP ?

Thanks in advance

If it is from an auto then it has had an easy life, so that will be a plus point

The Legacy JDM cars were 280bhp so it is capable of holding sustaining the same power

Fit the flywheel and turbo and it will be nigh on identical.

Grant,

Once again thanks.

Relief to hear this.

Hopefully be back on the road v.v. soon
