You'd prob need an intercooler upgrade and for sure a high flow DP with an IS38 on a 1.8. There are ways to keep temps down for sure.... But the lag wouldn't be good for Auto X anyway, mainly roll racing, hehe.As impressive as that guy's dyno is, I won't be following in his footsteps.
Maybe I've got a dog 1.8 but use for AX creates lots of heat for me and I now and then see trim spikes above 50, simply running JB4 map 2 and modulating throttle at high rpms in 2nd.
Maybe it won't be an issue for him. I hope not.
