It's got adjustable coil overs, 6 speed STI gearbox, 3RB diff and brakes in the rear end, braided brake lines and Bridgestone Potenza RE003 Tyres we've used throughout this series. With the compression ratio a very high 10.5:1, turing for performance becomes a knife edge exercise with one side being bulk power, and other - exploded parts, or more commonly with Subaru engines, cracked pistons and ring lands.Īnd the rest of the car? It's fairly well sorted as it is. I'd like to stay 3.6 if it's possible, but if the zero's keep adding on to the quote for parts, it may not be possible. So, now the mission begins to find parts that may fit the engine. It comes on boost quickly, it's smooth, and agile. It's exactly what you want from a fast, daily driven performance car. It's a pleasure to drive with a manual and turbo and unlike anything i've experienced. That said, the 3.6 is an extremely torquey and tractable engine. Being the first is always more expensive as you bear the cost of all the R&D. The 2nd option is expensive, probably out of the available budget for something like this. So where does that leave me? Either i can remove the EZ36 and build a 3 litre, of forge ahead with completely custom parts. The EZ36? It hasn't received the same aftermarket support yet, and may never do so. I've driven a Liberty with a turbocharged 3 litres and they are fast! You can also buy off the shelf forged aftermarket parts for this engine, which makes building a motor designed for more power easy. There was originally the option of using the 3l EZ30, which shares a similar design to the EZ36 but with less displacement and less torque. Firstly, the EZ36 was never designed to be boosted. ![]() So the car is painted, it has an interior, and can be driven around like a normal car again. The story of the driveline going through two shells is well known, I covered it recently in this post. There are basics like engine mounts and positioning, but its all the little things like engine management, wiring, neatness and even air conditioning that turn it from a 'toy' into a proper usable car. There's an art to getting an engine to fit into a car it was never designed to accept. It also manages to fit 3.6L of displacement into an block that isn't a great deal bigger than their 4cyls, meaning it would drop into most Subaru engine bays.ĪM Auto have a reputation of doing all kinds of weird and wonderful engine conversions. Turns out the EZ36 is one of Subaru's most advanced engines. Subaru Tribeca, a strange looking large SUV that looked like it was made for the American market as it didn't fit the usual mould of what Aus delivered cars are. I had to look up what the engine was from. "Build a 2.5l!" "Build a high revving 2L" "Throw a stock block in and boost it till it blows". We threw around the usual ideas that people who are into Subaru's do. Nothing I own stays stock for long, soon after I was talking to Al ( Turbo Yoda) about creating the ultimate Grandpa wagon. It was clean, straight and perfect for a build. They'd put it together from a collection of spare parts from front cuts after they've come across the shell. I'd picked up the first and original ' Gramps' from the guys at Ichiban. I've owned a few Subaru wagons and know them back to front so it seemed like the logical choice. It's got a flat engine, which in reality does limit achievable power - but it's also got all wheel drive, meaning that whatever power you do make, you can put that power to use. Rally wins proved it was a formidable car with good performance and reliability. Toyotas were mostly front wheel drive and Hondas were. Toyota has wagons, Nissan have wagons although not many locally delivered. Then there's euro wagons, they are more advanced but also expensive for parts in Australia. but the suspension and engine were fairly old tech. A rear wheel drive Falcon Wagon, it's big, parts are cheap and common. Years ago I thought about other cars that might achieve this. For me, a wagon was the best compromise of a car I could live with but also drive. It seems to be a common theme that people, for whatever reason, find a make or model of car that suits what they do and who they are. The Gramps and Supergramps builds have been an epic journey, one that now feels a bit more finished as the car is painted, looks mad, drives well and is an awesome all rounder daily.įor me this has definitely been a car that's used the best of what i've learned over the years about Subaru's. ![]()
