Thats a good question... I know they can repair cranks, but in order to grind down journals and re-polish and etc, it costs just about as much to do that (if not more) that buying a new one....I guess they could of got a used stock one in, and then maggied and QC'd it with some polishing?
Not only would that cause issues, if it was dropped hard enough to bust one off, you have to wonder if there are any other micro cracks you are unaware of. Take it back and buy a Callies Stroker crank from me =) (or at least exchange your current crank)
I know I have seen people do .060 over, never seen a .080 over, really is going to come down to your cylinder wall thickness., and application. You could probably get away with a .080 (once again depending on the wall thickness) depending on application, but the thinner the walls, the harder it...
I talked to the guys at MS (actually i think it was DIYTune using MS) at a trade show, they said they could make a Plug and Play MS version. Problem comes down to engineering time and everything that goes along with it. The 420a market is just not big enough to justify it. Now if you could...
I'd go to ShafTech Ltd: Crankshaft Modification/Repair Guys do amazing work, and well priced. My company has been known to even send some salvage work their way, have yet to hear a complain. Phone number is 419-435-6372, ask for Nick and tell him Steve sent you, he can hook you up.
AFX is the best (and i believe only) plug and play on the market. Its really nice, now sure how well it will work with 12.1cr though. With that being said, you will get more out of MS than you would the AFX, but it requires more work.
I'd recommend a custom one over the Megan, simply because the Megan was made for the average user, where you are going, 99% of the community has not gone.
You can always get the crank welded up and machined to specs, anything can be repaired with enough money. =) But do to the cost of something like that, you would be best getting a replacement.
With fuel and tuning out there, running higher compression turbo builds is more realistic everyday, but of course lower compression is always safer. As with just about everything in cars, there is no "right" answer, all give and take.For changing your compression ratio, your friend and Jayson...
It sounds like the heater hose should have no bearing on the car starting, if you have compression and fuel, just missing spark, so its trying to turn over, its a long shot, but did you check your engine link fuse? That will stop it from sparking.
