Welcome to All Drive Subaroo, Sydney’s pre-eminent Subaru service centre and engine repair and replacement specialists, located in Peakhurst, Australia. All Drive Subaroo evolved from Metro Mechanical, run by Niazi Helou, to become the biggest and most respected independent Subaru service center, parts supplier and gearbox and engine remanufacturer in Australia, with an international reputation for quality work and products.

ADS works hand in hand with Subaru dealers all over Australia to provide specialist services and products. The company has gone from strength to strength, forming alliances with premium auto engineering companies such as Cosworth and PPG to provide products for motorsport and other specialist applications.

Many hours have gone into research to identify inherent engine and gearbox weaknesses and to produce solutions. This led to the division of ADS into four specialist divisions and the development of many refinements in products and configurations. The team at ADS continuously moves with the times keeping up with all the latest industry developments.

All Drive Subaroo customers also benefit from our extensive trade contacts. We supply products to major players in the industry, with trade sales accounting for 40% of our business and 6% consisting of insurance subcontract work. This lower cost model flows on to our retail customers.

This is a 99 Subaru STI Coupe from Orange Subaru. We built a Cosworth engine and a 6 Speed STI Transmission for it, along with a fair few adaptations, including modified manifolds and custom Haltech tuned ECU. When it left our shop it was making 300kw at the wheels and...

“Upgrading my Subaru with a forged Cosworth engine was not a decision I took on lightly and am happy to say my experience with All Drive Subaroo has exceeded my expectations. Not only was I impressed by the amount of technical knowledge/experience Niazi and the team provided but what really...

James Knighton

Hi Niazi – just thought I’d give you some updates on what I assume is the only dual-range FXT in Canada 🙂 Car is running great – I have about 25,000 kms on the gearbox without any issues (there is a rattle at idle that goes away when I depress...

Warren Bolton

Hey guys Just wanted to say a huge thankyou for the service you provided me today. Was dealing with Nazi and what an easy bloke to communicate with. Ordered my turbo, gaskets and hose for a wrx and it is all in transit. That’s fast service in my eyes. Just...

Having bought a MY00 WRX (bugeye) without sufficient knowledge of the vehicle’s history and lack of maintenance routines that had been carried out on it over the years and several owners, I was in a sticky situation. Luckily, I stumbled across the details for All Drive Subaroo – the team...

Engineering Manager

Hi ADS guys! Thanks for getting me back on the road so fast. I’ve had this car for three years, and it’s never gone as well as it does now–can’t hear it running in traffic, and it just eats hills. Getting your reconditioned 2.5 liter engine was the best decision...

Joanna Doe

Hi guys, Just spoke to Adam about my sister in-law’s, (Leanne Gordon), WRX that now holds the lap record at the Marulan Driver Training Centre. Home The previous track record was held by her husband Roger Gordon with a time of 47.863 in the same car, as shown in the...

If you own a Subaru in Sydney and don’t take it to these guys you are missing out. Unparalleled professionalism, Excellent workmanship, and all work done well within the given time frame. Have a few more planned mods for the future and i wouldn’t go anywhere else!

I had my WRX inspected here before I purchased it from a Subaru dealer. They managed to squeeze me in even though they had a busy schedule and found out a few things that I got the dealer to fix before the purchase. They couldn’t have been more helpful and...
