A heavily modified MK2 Vauxhall Astra GTE

Ok so, as stated in the title this is a mk2 Vauxhall Astra GTE but with a twist. The original engine, a c20XE, has been modified and turned into a c20LET and at a rough estimate is currently kicking out 500hp (rough estimate as it hasn’t been on a dyno in its current state, all mapping was done on the road by my dad with me sat in the passenger seat holding a laptop). The biggest modification being that while the GTE from the factory was front wheel drive, this is rear wheel drive. This was accomplished via use of BMW parts with the gearbox being pulled from an M3 and the diff being taken from an M5. If you want a deeper look around, a fella named Twin Engine Corsa on YouTube did a video on it around a year ago: https://youtu.be/f9rfEQ0qL7Q

Or if you want to spend money and do some digging, Performance Vauxhall did an article on it a few years back (like 3). It’ll be difficult to get a paper copy as the magazine stopped publishing not long after
