Comment on I feel like if asbestos was banned today there'd be a huge pro-asbestos movement
boonhet@lemm.ee 3 days agoIt’s significantly harder to build hot rods or street racing cars now than the way you could in the 80s and earlier.
Unless you know how to remap a car and have a car with plenty of power reserve.
Anything turbocharged can be remapped for more power unless you’re at the limit of either the turbo, or the fuelling - and when you get there, many have options for more fuel and air. Diesels in particular are magic because you take a car that does ridiculous economy figures stock, and you double its power figures just to show people you can.
E.g Bobby Singh got 600 hp out of his diesel Audi wagon. These come stock with 240ish horsepower (176 kW or 239 PS I believe). He’s done engine internals upgrades to this one, but on other peoples’ cars he usually does bolt-on mods and gets about 400hp-500hp depending on what mods someone is willing to shell out for. Minus the upgraded internals, you could do this at home if you wanted to.
On the gasoline side, BMW has the B58 where you can get 500-600 hp with bolt-on mods and if you build it like people used to build hot rods, 1500 hp is doable. It’s considered the new 2JZ because Toyota itself put it in the Supra instead of building their own successor to the 2JZ. The 2JZ itself was a supercar killer when built properly.
On the Japanese side, I’m not sure if they’re doing anything fun new and new today, but they’ve all historically had at least one or two ridiculously tunable engines and Nissan will still sell you the very tunable GT-R.
Yes, some of those tunable newer engines come in pretty expensive cars, but there are still plenty of 4 bangers you can mod easily too. And it’s not like the hot rodders typically used small engines in the past. It was usually big ass V8s that you couldn’t even buy in most of the world because they used too much fuel lol

Right, that’s my point though. With my '84 Chevy Monte Carlo SS, I could drop a new engine in (started with a 305, ended with a 400 short block), do a high-flow dual carb intake, get a couple Edelbrock carbs, buy some headers, straight pipes and a glasspack muffler, and get a ton more power. (And also much, much worse fuel economy.) Now you not only need to understand wrenching, you also have to have the software and knowledge to entirely re-map the fuel, since it’s all computerized.
And while you are technically correct that you can get tons more power out of a lot of mostly stock engines, that does sharply reduce your engine lifespan. Of course, that’s always been the case, but it used to be that you could fairly easily get your block bored and sleeved to have larger pistons (“there’s no replacement for displacement”), but generally engines are running with much less material now. Oh, and they’re aluminum rather than iron, so often you’re going to have to send your block off to a specialist to get the cylinder bores coated for longevity. (I think my Honda CBR600RR had alusil or nikasil plating in the cylinders? I’m not sure now.)
I’m really, really not nostalgic for those days; yeah, hot rods are kind of neat, and it’s fun being able to do your own mechanical work, but cars now are so much more efficient, more powerful, and last 3-4x as long as cars from the 60s through early 80s.

Right. But with a lot of modern cars, you don’t need to drop in a new engine at all, and for a lot of people changing fuel trim tables is easier than getting carb jets juuuuuust right. Not to mention there are premade stage1 remaps for stock engines that should “mostly” work. There are engines out there that will give you around a 30% without a single mod, though generally not on those premade remaps, as those try to err on the safe side. Stock intake, stock exhaust, stock everything. Just a remap. Oftentimes, they give you BETTER fuel economy because of the improved torque curve. Though the increased effect of the fun pedal often cancels this out.
I’d say you can get into modding with less knowledge and skill nowadays, because as long as you have the hardware, you can get someone to remap your car remotely so you don’t even need to be able to drive it to a shop after doing whatever mods you want to do to it. True, if you want to do everything by yourself, then it’s harder.
