Would it be worth my time to instead of swapping a WRX engine into my car, put forged internals in my existing RS and an STi head and turbo it? Is an STi head even compatable with an RS block? the idea just popped into my head so I thought I'd ask.

That is what Skully has done on here. You should search for his thread.
That's what I'm currently doing -the sti heads.
And yes, it's cheaper by quite a bit.

so would it be better to put an STi block or STi head?

 

[Anti Trust]

generaly both would be better lol... but heads make the power you want..and you can "beef" up your block for cheeper

 

[TheHorizontalBob]

ahh how so? I already have a WRX engine sitting in my garage, BUT its never too late to change your mind, unless you start cutting wires then your pretty screwed haha

Put in STi internals (crankshaft,pistons,rods,race bearings) and call it a day. I'm currently doing it to my motor (same as yours). The cost is so much cheaper than buying a new STi shortblock!

 

[TheHorizontalBob]

that's whats up man, where are you getting your parts from? can you divolgue prices and whatnot?!

 

[TheHorizontalBob]

ZeroPunk is the man, he hooked me up with some great info

Sti crank is identical to the stock RS one, plus the crank isn't the weak link to begin with. Also remember the open deck block is a limiting factor in a very high horsepower build.

[TheHorizontalBob]

hmm, EM hadn't even entered my mind, I just assumed get it tuned..?

NVM I'm simple...the turbo kit i'm looking at comes with a rallitek pefect power smt 6
