Thought this would make for an interesting debate. I'm looking for opinions on what the best 4-cylinder motor of all time is. Keep in mind availability, versatility, hp/l, power potential, torque curve, sturdiness, history, etc.
In defense of the Chevy motor, according to the Ariel Atom's build specs, the Ecotec has proven to have a vastly superior torque curve compared to the K20, which is why they started using that motor for their Atom instead.
Also, the 4G63 may include all generations (4, 6, 7 bolt, etc.)
If anyone has any other additions, I'll be glad to add them in if I think they're worthy. I know the H22 and B16 aren't included, as neither was as race-designed as the other Honda motors included.
90-92 Mitsubishi Eclipse/Eagle Talon/Plymouth Laser pre May 6 bolt 4g63 and 4g63t motor. More towards the 4g63t motor which produces more power of course then the N/A. I've owned both. The 6 bolt 4g63 lasted around 230,000+ miles and 4g63t 201,000 miles. Thats my experience with them. So they are stronge engines and can take a vast amount of abuse.
No love for the Ford 4cyl? They race the hell out of those old Pinto motors in the midgets. Then you can add the turbo 4cyl in the Cossies. Or the 2.5 in the new Focus..... The world isn't F&F you know.
well, since the F20 has the most HP/L of any N/A factory motor, and its in one of the best factory chassis that gets my vote, swap-ability is kinda subjective as you can swap anything, but not like a direct bolt-in, thats what i assume your talking about. type-Ris #3 world record holder for hp/l but i think the L15 from the fit should be mention simply because of the technology of it, and if it were bigger, i think would be a very respectable engine The Truly Amazing Honda Fit/Jazz
4G63 without a doubt. Yeah, there are all sorts of other 4 bangers, but none have the reputation of the 4G63. John Shepard, AMS, APR, and countless other people running the crap out of these little 2.0 engines with insane power, let alone for such a small engine...I'm worried that the Evo X wont have the same potential since it will be so vastly different.... DI, all aluminum, more MIVEC...yeah it'll be badass, but how far will we really be able to mod it and get crazy insane numbers again? I only hope the new turbo Lancer replacement is actually powered by 4G63...Mitsubishi knows the importance of the engine:
not to start an argument but what does the availability of something have to to with it being the best ever?
What about the BMW M10?
The BMW M10/M12 was an I4 piston engine produced from 1961 to 1987. Displacement ranged from 1499 cm3 to 1990 cm3.
The engine was designed by Baron Alex von Falkenhausen, noted engineer and race driver. He was asked to design a small-displacement (1.3 L) engine, but felt that this would be insufficient for the company's future needs. Therefore, he designed a block that could be expanded to 2.0 L and delivered it at 1.5 L.
The design was very successful, with over 3.5 million produced, and it served the company for over 20 years.
The M10 engine is also one of the most successful engines in racing. Starting with the European Touring Car Championship, it was also used in Formula 2, then the Deutsche Rennsport Meisterschaft, were it was turbocharged by Paul Rosche according to FIA Group 5 rules.
The M10 block went on to Formula 1, winning the 1983 championship for Nelson Piquet and Brabham - something which very few 20 year old road car engine designs accomplish. The same applies for the rise in power, twenty-fold from 75 hp to about 1500 hp.
The BMW S14 engine for the first BMW M3 was based upon the M10 block. In the M3, the M10 is still winning races today.
Or the BMW S14?
The BMW S14 is a 2.3 L (2302cc) DOHC 16-valve I4 piston engine. It was used in the E30 M3. The S14 is essentially a BMW M10 engine block with a M88/S38 DOHC cylinder head (minus two cylinders). It has four separate throttle bodies. It developed 195 PS (143 kW/192 hp), or 200 PS (147 kW/197 hp) without a catalytic converter. A special tuned model, the S14 EVO producing 20 PS more. The 2.3 L version has a 93.4 mm bore and 84mm stroke.
Variations of this engine included a limited-edition 2.5 L (2467 cc) Sport Evo for motorsport homologation requirements, and a de-bored (89 mm) version for the 320is, a more affordable sports model made specifically for the Portuguese and Italian markets. The 320is can be quickly distinguished from the E30 M3 by the absence of flared wheel arches.
