I note that, in fairness, "package size" isn't much of a priority for most OEMs as long as it fits. I suspect GM bothered because they had the idea they could fit it into more places if they did so and they have the attitude of living with an architecture for a long time, so yeah, an OEM that bothered with shrinking engine package size successfully did so. You can do a bunch of things to shrink DOHC engine package size too but I can't think of many OEMs that bother. Blah blah blah, I'm going to stop making GBS threads up the thread about a badass project now.

It's not the best thread in AI because it didn't happen in Valentine. But boy do I have a line on a guy who could tune that bi-turbo for you. Cheap I bet.

I think we all know chevy goes with one cam small package because it is run by accountants. 25 cents per engine extra profit gets them a bonus weekly. It just happens that one cam is the best cam.

Driveline purity is a personal choice, and never anything more than that. If that isn't what you're going for, then by all means, build a monster and shove it into a tiny chassis because it is going to make all of AI giggle like a bunch of maniacs. I'm keeping slug-motor Toyota-only drivelines in my two Toyota trucks, but will still say that SBC-swapped Pickups/4Runners and 40-series land cruisers can be oodles of fun when you slam the skinny pedal.

While I do love an F20c because it revs so well and makes racecar noises with some breather mods and a decent exhaust, a big 'ol V8 with 2 turbos on it is pretty loving rad too... Also you posted on reddit, idiocy is to be expected.

Ha, worth it just for that. Have been involved with building a high powered track S2k and everything broke all the time. Blown up motors, broken transmissions, diffs, etc. Making it though one weekend intact was rare.

Not enough power band? Doesn't an s2000 have a teeny tiny powerband to begin with? I don't get why this annoys people but it sure is funny. Cool car.

NA that car probably put down more torque at the bottom end than the f20c did peak. And an s2000 perfectly fits in the small light car + big ol v8 = fast drag car formula.

No no, see, now it makes *too much* power; the optimum amount of power is exactly as Honda delivered it, trying for more upsets the blah blah blah blah blah

The truck motor thing is what gets me. High-end vs low-end power is mostly cam grind and F/A ratios isn't it? Why would it matter where the motor came from?

jamal posted:A lot of the truck engines are iron block and therefore much heavier. Correct me if I'm wrong, but isn't the advantage of the iron block (besides cost) is that it takes boost better? I'm not as familiar with the LS, but BMW's non turbo N52 was an aluminum magnesium alloy, but the turbo N54/N55 were iron blocks.

The "no powerband" guy has to be joking. An old man with an S2000 at my local autocross was always bitching that to get decent times he was either slamming off the redline in first the whole time, or shifting into second and bogging down. Also he blew his transmission, car was completely stock. V8 + small car is always the best idea, especially with turbos

In theory, yes, but the aluminum blocks aren't exactly weak, and (as the OP shows) can be built to handle a stupid amount of boost all the same. I like to imagine that somewhere in England in the '60s, there was someone frothing at the mouth about how DARE that Texan defile the AC Ace by putting some goddamn V8 in it!
