No, the 1.8 has less torque and a brake horsepower (meaning crank horsepower) of 127, meaning it's probably putting around 100 down at the wheels. This will crank it to 170 at the wheels and around 200 bhp. The Si has 197 bhp and about 170 whp stock, more torque, has i-VTEC, etc. The TSI turbo kit for the Si, even at 15 less whp (55 whp), gives it 252 bhp and around - going from stock numbers - about 215 whp or so.
It might be a "good match", but the Si will still beat it even with the 15 whp difference in the turbo kits.
It'll keep up with a bone stock Si, but the torque difference may not mean it will beat it. Keep up, yes; beat, eh, depends. That's still sick output for the R18 and I'm very impressed with the kit. I know a guy in PGH who's looking to buy it for his EX, so he'll be all over this thread.
