You can keep the Toyota badge and have more ponies than you need w/o going to a V8, Toyota has 2 I6's that will will produce anywhere from 220-1k HP. On a budget build a 7mgte swap is good for 220-500hp, and can have 400hp for under $5k, while the 2jzgte will produce 400-1k hp for $5k-?
I had 1984 Supra..... that engine would NOT be my choice for a Toyota engine swap for my truck!! And... getting that engine to HP greater than stock would be WAY more costly than $5,000!! Or.... can you enlighten me?
