I hate this mentality that seems more and more common nowadays that older engine designs cant make good power. The L28ET could push 250 horses too, for way cheaper than you could even swap in an SR20. Not to mention, a 250 horse L28ET will make bags more torque than a 250 horse SR20. If you want to race uphill, torque is very important.
Not to take anything away from an SR20 or any other modern engine, of course, they all have their pros and cons, just dont knock the L28 till you know alittle bit about it is all.
