Can you enlighten me as to which manufacturers produce a much higher powered or more efficient 2L as utilized in a high production economy vehicle? Remember, the 155hp rating is as installed in the Mazda 3, which is NOT the most efficient/powerful variant of the 2.0 Skyactiv. The Miata will almost certainly benefit…

definitely NOT Atkinson cycle (despite what Wikipedia lists..and definitely not an electric hybrid,lol). It uses a trick or two with intake air manipulation at light loads to mimic some of the gains (to a lesser degree) that come with Atkinson. 75+hp/L and 75lb-ft/L are way higher than an Atkinson cycle engine would…
You should change your reading material..hard to imagine the Z31 chassis being better than much in the past 20-30 years! It was a (very)meager update of the 280zx-itself dated from late '70s
Definitely amazing (in a bad way) that Ford released their halo performance car and it took owners' (who dyno'd/stripped them) complaints for them to realize their was even an issue. And that 2 small problems with outsourced manufacturing led to the demise of an entire model year's production! Couldn't imagine a…
01 Cobra was fine. 99's had the problem, which Ford issued a fix for, and is the reason there was no 2000 MY Mustang Cobra.
Ford realized that they had an issue with under-performing 1999 Cobras and issued replacement components to bring power up to advertised levels. Ford corrected the manufacturing problems (took a while- as there were no 2000 MY Cobras) that caused the lower output, and the 2001 Cobra had a genuine 320 hp.
the 1999 Mustang cobra was not "over rated", it was affected by manufacturing glitches with intake and exhaust components which reduced the actual output to approximately 5% below the rated 320 hp. After the problems were identified, Ford applied a fix to sold 1999 models that restored the actual output to the claimed…
Just a rough guess , but the LT1 should put out about 350 hp at 4k
actually, the Stealth/GT(O) replaced the Conquest/Starion in the US. DSMs were sold concurrently during the 1989 calender year.
Sorry, I just used "US legal" to exclude any homologation specials that Honda may have released over the years. Ironically, about half of all NSX production was sold in the US-1500 more cars than in Japan.
Considering that Honda never achieved 300hp in a US legal NSX, Toyota had a lot of reasons not to put a bespoke engine in a vehicle less than half the price,lol. That was Honda's forte..all aluminum high revving engines. The B series was probably not far from a million produced. That was my point, Toyota had no…
Keep in mind that the Z32 predated the FD and Supra by 3 years. 75 hp/L in 1989 was anything but "mediocre"- Toyota's 7m-GTE (their top performance engine in 1989)produced only 10 more hp (232), even with the aid of an aftercooled turbo. The Turbo Z's 100hp/L was unheard of in a US legal production car-aside from the…
Ferrari 308/328, Lamborghini Miura, Lamborghini Urraco/Jalpa, Lotus Elise/Exige/Evora, and Honda NSX were all transverse engined.
I don't know what other engine choices Toyota had available that you could be referring to. The alloy block 1MZ V6 didn't debut until 1994, and with only 190 hp. Cast iron four cylinders were about all that they had for options. As mentioned by others, using high volume production drivetrains from the Celica/ Corolla…
It's a well known fact that Wiegert was a snake oil salesman and dealt in vaporware for the majority of Vector Motors/Aeromotive's existence. I'm sure there were 1000hp prototype engines, but a 26% increase in absolute manifold pressure (8-14 psi boost)won't turn 650 into 1200hp (closer to 800 under ideal conditions).…
Corvair was REAR engine- can't flip an auto box like a Porsche G50! I remember the Vector's being based on the front drive Cadillac/Olds THM425. Did the Corvair EVER have a 3spd auto?
Laser was actually available with AWD from 1992 MY until death.
3800+ lbs on an Eclipse/Galant chassis (even has same wheelbase) is something worth questioning, lol.
Sorry, was replying to using the GN engine in general. Fiero was designed for transverse FWD powertrains, including transaxle. Buick 3.8 turbo would not have been an option.
