fitting a scoob turbo

[scooters]

OK, before I go to the UK Legacy Forum and ask this question I thought I would answer it here where I am less likely to get the:

OMG WOT U WANT IS A YOKIFLAPPA 3000000 TURBO WIV SUPER DOUBLE DUMP VALVES - 5 GAZILLION BHP NO PROBS - GET RID OF THOSE OEM BRAKES AND SPEND £1000 ON NEW GREEN DISCS N PADS N WHILST R AT IT GET SOME COIL OVERS THERE ONLY £700 A PAIR!

 

We have a 2000 Subaru GL Estate which was originally fitted with a 2.5 quadcam engine. Now that engine blew up some time ago and was replaced with a 2.0 WRX engine - naturally aspirated.

 

Do any of you brave fellows know how tricky it is to add an OEM turbo to this - I suspect the turbo and plumbing can be bought 2nd had as could the ECU.

 

This weekend I drove to Durham and back and whilst well behaved the car didn't do what subarus should do and was a bit dissapointing especially when overtaking.

 

any ideas?

I'd guess the 2.0 WRXXXXXXXXXX engine will be pretty bloody gutless indeed if it's running N/A - It'll probably be lower compression than the normal 2.0 (Which is no rocket ship from memory)

 

You can probably run it on two star though

 

 

EDIT: Yeah, its 8:1 vs 9.4-10:1 for a proper NA tooleater

Won't you need to uprate the internal too if you're putting a turbo on? If the pistons etc are different I would expect some sort of meltdown to begin before too long.

All WRX's came with a turbo.

If it's that engine with just a standard downpipe, you should be able to put one on, but what ECU/fuel pressure regulator does it have, etc?

[Volksy]

Is it a 2.0 with single cam heads, or a 2.0 with twin cam heads? Single cams were never turbocharged - not in the uk anyway.

 

I think it would be far easier to swap the complete engine, for a turbo one, or to be honest, the complete car. They are not exactly expensive, and I expect for the cost of turbocharging yours, you could probably buy a turbo legacy.

 

In theory, given the correct engine, you would need...

 

Exhaust manifold and pipework, Inlet manifold and pipework, airbox, turbo, oil feed (and holes for such drilled in the block), mounting brackets, ECU etc.

 

In theory, you can turbocharge anything, whether it's worth doing is a different matter.

+1 on what Volksy said. To many variables and what-ifs.

Ta all...we will keep as is for the time being and replace the car next year
