If you want to waste some money, I believe you can use a Vortech on the 5s-fe.

But make sure your unit is in working condition, this one had a leak and shortly after the dyno the project was scrapped. I'm not sure, but I think Trent may still have the setup (the seals need replacing, there wasn't much else in terms of damage) lying about.
