I've been running a McLeod SFI unit for 4-5 years. It is basically the same as the Lakewood, but has variable mounting holes on one side so it fits both a T5 and Tremec. It is very heavy and a bit bulky and depending on what headers you use may need to be clearenced. It required a longer clutch fork and as with any non-stock bellhousing the runout (dialed in) should be checked during install. Mine cost about $280 I think.
If I were to do it all again I would get a QuickTime bell. They are a bit more expensive but much lighter and not as bulky.
Is your T5 stock? It may or may not last too long at that power level, all depends on how much it's abused.
