Lots of good advice here. Thanks pwpanas.
Good luck with your plans warmkop. I suggest that you take this advice because, it doesn't require you to radically change the car. I believe Supra is rock solid and a legend who's integrity should be kept intact when modifying it. You couldn't find a better car to own/drive/race stock standard or modify. All thanks to Toyota's excellent engineers - Tsuzuki Isao-san and his team did an incredible job
Just some fyi for you pwpanas:
As warmkop said, Supra is fully imported here because Toyota didn't send it to SA. No spares or support can be acquired from any Toyo dealer here in SA unfortunately. I'm all for OEM replacement parts as far as possible. Our Supras are JDM spec - USDM is LHD which is not allowed here. UKDM can be bought at quite a premium. JDM Supras are more popular even in Britain. If I remember correctly, JDM Supras have MAP sensors as opposed to export spec's MAF sensors. They also do not have EGR (thank goodness!) like you mentioned before.
