s14sr20det with HKS Hi Power 60mm piping, for now...
What’s up everyone. I just test drove my s14 with the s14sr in it. A few things to note: It still has my HKS Hi Power ka exhaust with 60mm piping. It has the stock side-mount i/c, an HKS DD filter and a Tomei 255lph fuel pump. Klay at Motorex also set the timing back to “break in” the engine. With that in mind, it felt like a strong engine and it was very smooth all the way to 7000rpm. It also felt “restricted” and a bit sluggish, though. I will be getting a gp sports spec R stainless exhaust with 80mm piping this week. Do you think adjusting the timing and replacing the exhaust will make a big difference? Thanks!
