Right, and you're operating at the motors limit, and a lot more likely to have problems, also if you decide you want to get serious, you are pretty close to maxing the D's power without a serious rebuild. Or, you pay a little more and get B16A or GSR, and down the line boost that, then you're easily turning more than a D without even having to crack open the block. So yea, immediate budget, sure boost your D, then replace every couple years when you push it too hard, or get a stronger starting platform to begin with, and consider it an investment, either way, it comes down to personal choice.
