Looking To Turbocharge A 2012 Mazda 3 2.5l Engine With Auto Tranny

Can I put a V6 engine into a 4-cylinder car?

If the car was originally delivered with both types of engines, it might not even be very hard.There are some special considerations though. The first generation of Saab 9–5 was delivered with three choices of engine (I’m leaving out the diesel engines, they shouldn’t be in cars anyway), a 2.0t I4, a 2.3t I4, and a 3.0t V6. The 3.0t was only delivered with an automatic transmission, while the smaller engines were delivered with both types. Converting a 9–5 2.0 manual to a 3.0 automatic is probably going to be more work than converting a 2.0 automatic to 3.0 automatic.Then, on the other hand, you might achieve your goals in much easier ways than complete engine swaps, depending on what those goals are. As original, the 2.0t has 150 hp and 240 Nm, while the 3.0t has 200 hp and 310 Nm. If the goal is to increase power and torque, a simple software upgrade to the 2.0t will give you 210 hp and 320 Nm, meaning you get more power and torque than the 3.0t, while retaining the better fuel economy of the 2.0t. Of course, the 3.0t could also be software upgraded, but it is a very strange engine that is very hard to get much extra power from, so you’ll probably increase the power only from 200 to 220 hp. If you want more power than a simple software upgrade will give the 2.0t, changing to a bigger turbo and more open exhaust can make that little engine yield much more power than the weird 3.0t could ever hope for. Strangely, the 2.3t was sold completely original in a version with 260 hp and 350 Nm, noticeably more than the original 3.0t, so the Saab 9–5 was faster with the strongest type of original 4-cylinder engine than it was with the V6.However, if your goal is smoothness rather than outright power, the V6 would probably win every time.

Are Volkswagen engines tuned down Audi engines?

Audi and VW, like all other multi brand companies, share components. Engines and transmissions are shared across the entire group in many cases, across brands, and segments (sports, luxury, SUV, etc).Engines in particular these days, can have various states of “tune”, based on ECU programming, fuel/ignition curves, and possibly, cam timing. But they are still the same engine.Turbos in particular are easy to vary power production with programming. Naturally aspirated cars can do that too, but there’s less degrees of freedom there, and the only thing that really makes a difference in a big way is compression ratios. Everything else is around the edges (cams, curves, exhaust, etc)You’re certainly not an idiot, as the logic is correct. Whether the “tuning” is different or not kind of doesn’t matter, as the only thing that really matters is torque and horsepower delivery curves, and how the car actually behaves.Furthermore, as far as engines are concerned, most global companies that sell cars everywhere, “tune” their engines based on local countries/regions/markets tax laws (emissions/displacement/top speed), as well as local driving habits (manual trans/auto), or other local characteristics. The identical engine may have HP from that varies from say, 150BHP to 220BHP, based on where it sold, and how it may be taxed (road tax/VAT/sales tax/etc).I have both Audis and VWs now, and while I personally don’t care, I do know that they share a ton of parts in common. When I do a parts search on a specific part number, it comes up as a cross application part in many cases.I would say your “friends” don’t really know what they are talking about. VW group uses core engines across their line, Porsche, Audi, VW, Skoda, Lambo (yep), etc. And also, the 2017 US based Jetta, shares many platform components with Audi Q3, and the last generation Audi A3.

Which transmission is better, an automatic or a CVT?

Clear answer: CVT. Would I get one any time soon? Hell no.CVT’s are incredibly practical. They have fewer moving parts than a conventional transmission, and can be electronically adjusted to make any gear ratio needed. Its pretty much a belt sliding up and down two cones:When you think of CVT, your mind probably goes here:But what if I told you, that a CVT is something every one of the following cars WISHES it had?Thats right. CVT’s were BANNED from formula one competitions. That should tell your something about the misconceptions about these things. The key feature is their ability to be electronically tuned.We find CVTs in a bunch of teensy Japanese econoboxes because they can so easily be tuned to maximize fuel economy. However, we can just as easily tune these things so that they maximize power. The ability to be at 100% power, all the time was just too much of an advantage and the technology was banned from formula one competitions before the Williams prototype made a single lap.Then comes the natural question, why does every gasguzzling horsepower-injected tire-burning hot rod not have a CVT? The only good reason is tradition. People like to take their barking V8 up to redline in second gear, to be able to tap the left shift paddle on a turn and barely hold on to the road. Anybody who’s driven a Honda civic knows that you get just about… none of that. But eventually, as these sports cars get choked by emission standards, they are going to have to bite the bullet and trade in the gears for the far better belts and cones. But for now, I’ll drive whatever kind of transmission comes in most fun cars.
