Ok, it's June, and the time for my yearly review has come and gone. Everything went well, and they decided to increase my salary by 20%. In celebration for this new found wealth I want to purchase my car upgrade for the year. I drive a lovely Hunter Green 97' Supra TT which already has 480 HP...however, that's not enough for me. I want more. Time to go from twin turbos to a larger, single turbo. The question is, which one. I'm either going to get the Stage 3 or the Stage 4 kit from SupraStore.com. One pushes 700 HP but spools relatively fast...the other is pushing 800 HP but is the larger, and slower, T-88. The question is, which one should I go for? Or should I do nothing at all, and save the money. This is where you at AnandTech come in. Help me decide what to do, and if you're ever in the Nashville, TN area, let me know and I'll let you drive my car.
