Turbo charging a car that didn’t come in a turbo variant makes more sense than turbo charging a car that had a factory turbo option.

Very true, but the Miata does come with a turbo. It’s called the MazdaSpeed Miata, but it was only produced for a few years and it’s probably worth 40% more than a clean example of a NA.

I think in the grand scheme of things anything other than NA won’t be as reliable as NA simply because of more parts being more points of failure. Combined with people tending to abuse turbo/SC cars more than NA there will be a higher percentage of blown up turbo/SC cars.
One of the teachers in high school had a WRX he abused so much it shattered two pistons. At the same time I’ve seen WRXs driven by grandmas that run mint even at 150k+ miles.

Essentially, if you want power, don’t get the factory turbo variant, because you just need to upgrade everything anyways. The factory turbo spools at 1500rpm but hits boost limit around 15psi.
True that. I saw a N/A version of my Volvo with an absolutely absurd 600k on it, and the guy said it’s never been rebuilt… Who knows if that’s ture, but it was very clean.
And those N/A engines love boost. 10 pounds easy from my research on my Escort GT with the 1.8 Mazda BP engine in it.
And the speeds are very expensive and rare.
Yeah, I’ve got a friend who ran 300RWHP (~19psi) on a stock block.
The awesome thing is it’s got an extremely strong bottom-end from the factory, so realistically, the limits on a good engine in stock form is about 350BHP. The problem is that the diff goes at 225 and the tranny starts losing it around 250.

LMAO That looks like too much complication.
Honestly, there’s no reason to use more than one turbo, unless you’re doing different sized snails so you can get small boost early and really lay it down around 5 grand.
Twin turbo can be a better option then one for V engines.
Ehh, it really depends on the car and how much room you have.
Look at subaru. Flat 4/6. one turbo.
Yeah, I’ve heard tell of a Subaru dealer providing a very good trade in for a Forester that had something like 500k on it. I guess the plan was to actually take it apart to see if they could learn anything from a super high mileage car.
EDIT: And to use it for marketing purposes touting the reliability of course.

I mean, don’t get me started on the LS430 and it’s notoriety for being indestructible.
That’s why I said “it can be”. I still haven’t done enough research to know what the exact pros and cons are, but from what little I’ve gathered, generally one turbo is a better all around option.
I need/want to know more about turbos. Research for another day though.

It is. you get slightly less rotational mass, so you need less energy to get it to the same level of power.
They’re super fun to research.
Technically, since they’re using waste energy from the exhaust, you can claim your car is “green” because it’s recycling.
Tree huggers don’t like that my race car is green though.

Turbos are generally more fuel efficient than superchargers too precisely because they use the exhaust whereas superchargers use pulleys and belts. With SC you essentially take power from the engine to make more power. Turbo you take essentially used air to make more power.

Yes. But you only notice the benefits when you’re in low or no boost.
The marriage of fuel and air (consummated with a well-timed spark) is what creates power, so yes, more air is nice, but you’ve got to add fuel as well.
Talked to my body guy about the rust one the driver rear… decided 3 grand was not something i was prepared to pay my all in budget is 3 grand and the car was 1.5… so on to looking for another car and the mythical elusive EJ22.
Just grab a legacy with a decent body, drop an EZ36 in it and be happy as a pig in mud. I’m sure a junkyard EZ is probably $750 and it should mate up with the legacy tranny just fine with the right motor mounts.
