Toyota MR2 Message Board - View Single Post - 3S-GTE JDM 3rd Gen Turbo Engine New findings on 2.0 ct20b GenIII w/mods

That dyno graph has the typical fluctuations on the topend from the flapper door opening on the ct20b that we incountered. We are now in the process of making an upgraded actuator since HKS does not offer this for the ct20b turbo. For some reason my green mr2 has a stiffer factory actuator than the other genIII ct20bs we dynoed for comparison in the shop. That accounts for my car being able to run more boost/hp before this would occur.
