This is a discussion on The Type of octane to use? within the General Maintenance, Troubleshooting & Accidents. forums, part of the Tech & Modifying & General Repairs category; so if i completely build my engine and nothing ever goes wrong there wouldn't be an claims therefore the warranty ...
Things will go wrong, no matter what you think. If you don;t use the right, or same sealant they'll be able to tell just by the color of the gasket someone else toiuched it. If you need to have your engine rebuilt and see any aftermarket pistons.
There's plenty of ways to tell.
And you can never say nothing ever goeswrong because parts wear down and you will have to get them replaced
I use 93 octane, I figure the extra two bucks per full tank is worth not getting a knocking sound 5 years down the road.
DD = daily driver.. the opposite of a drag car.
If you go by what Subaru says the STi being 300hp, that should make my bugeye around 650hp come December. There's a lot of thought and research that goes into building a high hp reliable 2.5L car. Of course these days 500whp isn't unreasonable, when just five years ago a reliable 400whp was wishful thinking [I was reading an old rod thread on nabisco today from 2005 where people were questioning why anyone would replace STi rods because no one had ever seen one fail, now I'm going to be replacing my Manley H-Beams for Pauter X-Beams because several people have broke the Manleys at 550-600whp]. Once you go over around 560-600whp then you're talking about a car that is just useless on the street.. no power till after 5500rpm. I know at least three people here in TX at AWDTuning that make over 600whp (one over 700whp), probably a dozen over 500whp.. It can certainly be done, but we're talking $20,000-$30,000 in modifications. Then you have to deal with constant issues/rebuilds. If you're going to spend the money on a 500whp car, I suggest having an equal amount of money set aside to fix it when it breaks. And you should certainly have another car to drive when it's in the shop.. ask me how I know.

i figured out what DD was but thanks... i do have another car my first car which is dreadful to drive no excitement(2000 Ford Taurus SE)... i know its going to alot of money make such a nice build and make it properly so I'm on the fence on how to do it. should me and all my mechanic friends do it(save a lot of $$) or do it professional and people who have an idea how it should be done(spend more $$) what i mean how it should be done is they have made other subi's 500+ .they know all the in and outs. of course i should have money on the side cause if i don't my car is just going to sit there with being repaired...
