Dear Sifu,
I recently did a top overhaul on my stock 4G93T engine.
My mech used the 4G93 NA metal gasket on my engine.. so this is what happened.
Pros
1. Very Good Pick-Up & Acceleration.
2. Car feels a lot lighter and good responds at low end to mid-range RPM.
Cons
1. Overboost - 1.7bar...
2. Engine Knock at high boost - a potential blown engine in near future.
How can I fix this problem?? Suggestions from my mates are;
1. Installing an external wastegate - (but TD04L is too small for ext.wastegate)
2. Installing Electronic Boost Controller - (AVCR - damn expensive)
3. Installing Additional Injector and Controller for sufficient fuel to prevent detonation.
4. Installing Bigger Turbine to Lower the Boost.
5. Do not hit full throttle......
So what can be the best solution for my problem?? Any ideas? Can the Ext.Wastegate solve my overboost problem? Anyone used the Nitro Wastegate? I heard it tends to leak. If possible I would love to have the cheapest alternative.
Thanks in advance for sincere help from u guys in ZTH.
