It takes advantage of Toyota's Variable Valve Timing (VVT) technique about the ingestion cam, a heightened compression ratio (10.
In accordance with Toyota the Timing and COs cant be adjusted on earlier mentioned described 20V. I am aware needless to say the COs cant be manually modified but changing the distributor does come up with a huge difs! I heard the ECU on the blacktop 20V can progress or retard the timing by about 5 deg!!
Without the VVT operational there really should be a significant loss inside the mid range electric power. If there isn’t a recognizable reduction then it’s very likely the VVT pulley is now not useful and needs substitute.
Odds are it is simply reacting towards the inputs it can be getting. Wherever may be the WBO2 sensor located ? In one of several header tubes or after the collector ?

I is going to be creating a wiring harness for my new motor that just arrived. I'm intending to doc every single step so it will help those people who are determining to journey this road. I will be including diagrams of the pinouts with shade coding at the same time.
This is some pics with the harnesses. the 1 Along with the blue tape may be the 4age 20V Black top rated harness. the other harness can be a 7AFE handbook harness. showing a number of the plug similarities.
