IIRC, that was during the fuel/energy crisis when severe emissions regulations were brought in - everything was hardcore detuned/restricted because that was the most cost effective way to meet the regulations. They also put a bunch of small engines in their large cars. If you look at American engines of similar size from the 60s, or late 70s, the power is a very different story!

Nonetheless, torque was more important than power from these engines as they were coupled with tall gears/diffs and even with limited power the bigger engines still pulled respectable quarter mile times. It also didn't stop people from modifying them to remove the restrictive nature of the engine.

I just find it surprising the most common (and successful) motors at world time attack are 20 years old lol

As much as i wish people could manipulate and change modern engines the same way people do 90's engines... Its just not heading that way. Even if there was a large customer base, theyre getting harder to crack.

The only real modern engine i can think of that still gets massive modification treatment is the LS series, but the base motor has been around for ages

Actually I don;t think it due to not being able to tune the egine, look at the R35 for example.

I think a fair bit of it how heavy the cars ended up getting.

now that they are looking at efficient cars getting lighter again so I think the next generation will be looked at for TA again.

but think about getting around a corner,

Evo 8 is 1320 kg,

R35 1740

S15 1200

with a limit to the weight reduction based on a % factor you still end up with a very heavy car and weight is the bane of racing.

What kind of engines are you talking about?

RB's, SR's and 4G63's?

These days when its all about cost cutting efficiency, fuel economy and emissions, there's hardly any Over-Engineering which allows you to make 2-3x standard power on an engine, simply by adding boltons...

^exactly...? Over-engineering is certainly cost cutting from a tuning perspective, but look at subaru... Many parts are like glass but theres demand and therefore solid replacements. Just most of the base motors are still over 20years old lol.

But theres no V8's, and few 6-cylinders even. Rotories are really only still in the picture because their fans are purists

    • how do you know voltage is fine?  quick easy test is connect DMM up and put it on max/min mode, remove fuel pump fuse, crank car for 3-5s, go check min voltage You'd be surprised how many "healthy" batteries are showing under 10v during this test in cold weather. 
    • Not properly. You need to be able to dissipate 100 amps or so to doing it meaningfully. You can do it indirectly by watching to see how far the voltage falls during cranking. Unplug the coils or something else to prevent it from starting so you can get a good couple or three chugs. It also helps if you have the multimeter set up reading before you start, and that it has max/min functions. So you can catch the real minimum without having to watch the screen, which often doesn't update fast enough to show the real max/min in dynamic situations. Or use a digital oscilloscope, which can be obtained for <<$100 from Aliexpress (although I'd argue for paying up to ~$200 for a nicer one). A >4 yr old battery will very likely be well down the path to the knackery. Many only last 5-6 years these days. The cold weather lately will definitely make it worse.
    • Hmmm, what do you mean by getting weaker? And where did you get that test done? I've been wondering about my battery because the cold starts crank super slowly. The voltage is fine. Not sure if cranking amps can be checked at home. Battery is 4+ years old.
    • No. The simplest wastegate hookup, with no solenoid or other form of "boost control" (ie, control over your boost control, if you know what I mean) is a single hose, direct from the turbo outlet/hot pipe, straight and only to the wastegate actuator. It is that pressure signal that drives the wastegate to open, providing the boost control (and by "boost control" here, I mean, limiting how high it can go, which is essentially the spring pressure of the actuator). You only end up with tee pieces and alternate flow paths once you start adding things to the boost control system to allow you to determine how much of that boost signal makes it to the actuator. There are so many ways to do that that there is no single way to run the hoses and tees and the like. If you have a stock boost solenoid, then all it does is either allow all the boost signal to go to the actuator, or open up to allow some of it to bleed off. There needs to be a restriction in that bleeder to allow only a small amount to bleed off. And in a stock system, that would then be plumbed back to the turbo inlet (for "emissions control" reasons). That is actually what that nipple on your BOV return pipe could/would be for. If you have an aftermarket boost controller and solenoid, then the above is mostly true, but there is no need for a restrictor in the bleed, because the solenoid is pulse width modulated to create a variable bleed off. The air that escapes from the bleed can either be vented, or also returned to the turbo inlet. For emissions reasons it should be returned to inlet, but the amount of air being vented is so small that it really doesn't matter (either from an emissions perspective, or from an air-fuel ratio affecting perspective).
    • And other times you just need to go buy bigger injectors?
