Make a right decision, you've got slightly distorted thoughts over this. You need a fast and reliable car? You can always spend money on a k series swap for this 7th gen instead of spending extra money in order to get your hands on a 8th gen which will require additional money on the top to make it faster. So, pick a side first. Do you want a faster car or do you want a newer+fast car? The more you want, more you'll be lookin at the end of spendings. Decide the purpose first, be serious and stick to it before you start spending in bits and pieces and doing experiments ending up in wasting everything and making it all completely worthless eventually.
