Most Reliable Power per Dollar Spent!?

[TitoRay]

If you have the resources, skills, etc., do whatever you want. If you have the money, Jake Raby of www.aircooledtechnology.com (thats a .com) is a well respected engine builder who is obsessed with the precision and perfection of his trade; type 4 engines. The engines he builds have a purpose and a reputation of being high-powered and long lasting.
Simply put, a 100 hp type 4 engine would be a more logical choice then a 100 hp rotary "conversion."
If you are running huge meats and want to eat Mustang GT's(me too! ), 150+ hp might be what you want, obtainable via both rotary and type 4. High horsepower(turbocharged?) rotary engines require an intercooler setup(correct?), and more custom work. So if you have what it takes or want to endure the task of installing a rotary engine, go for it!
If you have the funds, you can buy a complete turn-key engine, tuned and ready to haul balls from Mr. Raby.
Of course, their are other lesser-known options as far as combos, builders, etc, but thats another story.
High-powered type 1 engines do well at the track. 11-12 second et's are not uncommon, but driving a type 1 engine capable of these times everyday is not very realistic.
From my point of view, based on your words, you might want to go rotary. A tire boiling 250 horsepower is more than possible. But then you have to consider tranny upgrades, etc.....
