Ye HPE are pretty good, and ye big power n/a aint the cheapest way of tuning, but you shoot up the classes if you use forced induction. If you can afford to live without the drivability then go for it I say, had a run in a mk2 some time ago with a dry sump 2.4, didn't idle well at all but give it a touch of throttle and it was well worth it!
HT Racing at brands,talk to Aaron,built me a couple of pinto's on 50's with reasonable drivability but massive top end!!
