NZ Performance Car: Hi, Rohit. How did you get into cars and what was your first?
Rohit: Hi, team. I’ve always been into cars from a young age. Though, it was through mates playing around with old VR4s and GTXs back in the day that I got into the modification side of it. My first car was a little Mazda Eunos bubble hatch, but that didn’t last long at all before I decided boost was needed.

And how long was it before you ended up with this Evo?
After the Mazda, I had a couple of turbo Subarus, but the last Legacy [that] I owned started sounding a bit rattly, and this Evo came up for a very reasonable price, so that was it.

Did you always intend to modify it, and to this extent?
The initial plan was just the usual bolt-ons and seeing how we went from there. I then started hanging out with the Untamed Motorsport crew, particularly Carl (JRCOZY) and Chris (Al4SPN). That caused things to escalate quickly … I picked up the turbo, and we decided to see what the stock block and ECU could manage. The block decided to self-ventilate and instead of building the usual 2.3-litre stroker motor, we did some research and sourced a few parts through Alex from Moonlight Racing to piece together a 2.4-litre using a 4G64 block.

Nice, and what do you hope for the future of the car?
I just want to see what we can do with this set-up now that it’s going. The goal is a 10.99-second quarter-mile, so we’ll be working towards that. Realistically, it’ll be E85 next if we need more power — I’m reluctant to go bigger with the turbo as it’s still a street car, and I’m not interested in a lag monster dyno queen.

Got to stop somewhere, right? Thanks for sharing her, Rohit.
