NZ Performance Car: Hey Roman, that’s an angry Weekend Warrior you’ve got there. What made you choose a Subaru to modify? 

Roman: I wanted an all-wheel drive because they handle so well, and I’ve always like the Subaru rumble. 

Why a Legacy wagon?

I wanted to be different, going with an older-generation Legacy because there aren’t as many around that have been modified to this extent. Nobody expects it! 

What modifications did you start with on the Legacy before it turned into a wild engine build?

 It had already been converted to single turbo when I purchased it. It was putting out roughly 230kW with a TD06 turbo and a stock V7 motor. I got used to the power quickly, and that’s when all the modifications began. 

What was biggest hurdle with getting to 317kW (425hp) at the wheels with an EJ engine?

By far the biggest hurdle was the factory bottom end, and choosing the best turbo to match the set-up. 

What’s it like to drive now that the set-up is complete? 

The new set-up is perfect. Full boost — which is 26psi — comes on at around 4000rpm, and it holds it right to the redline. Also, it’s really drivable when I just want to cruise around. 

Thanks for chatting to us, Roman, we’ll see you around this summer.
