Jake doing Subarus?!?...

[70Turbobug]

It boils down to what you are wanting to spend and what you actually expect your next engine to do.Be assured that a Jake Raby conversion package or turnkey engine will be pricey.The quality will no doubt be excellent.But if it´s bang for the buck you are after,you might want to consider something else.If you have the capabilities to build an engine yourself,then a suby conversion will be a little cheaper if you can find a good donor engine.It´s the same game as with the type 4 the difference being that a good suby engine is easier to source and the aftermarket parts are plentiful and usually cheaper than good type 4 aftermarket parts.If you want modern commodities and a modern engine that is nearly trouble free,then the suby is the right choice.HP/cubic inch isn´t any higher than a type 4 either unless you really sink a lot of cash into it and go for all out high dollar race components.If you´re looking for the most HP per dollar then a rotary is the best choice.With good porting and a single 48mm IDA carb those little suckers pump out 280HP@8500rpm and you can do it for under 2000 dollars.
My opinion is if a fun daily driven turbocharged engine with real heat in the winter and long life is what you want,then a suby is really the best choice,even though I am a die hard type 4 guy.
