Hi, I'm looking at getting a VT Series 2 3.8l or 5.7l and I was just wondering what are the cheapest upgrades could you make to either of these, to raise it to the performance of a Nissan R33. Which would mean a power to weight ratio of 7.34 kw per kg (The R33 has 1367kg and 186kw). And increasing the handling substancially. Just wondering what configuration of upgrades I could make to either of these to attain these performance levels, and which would be the cheapest? Thanks.
