I would say any B series Vtec motor. Reason being they have one of the best flowing heads made from the factory. The make some of the most power for thier size and are very reliable. That is untill you boost the hell out of them.

The Honda Magna. One of like 3 V4 motorcycles ever produced, and the early 80's 1100 ran SICK times (10's) for a cruiser. DOHC, liquid cooled, direct cam/valve acutation, 10,000rpm redline stock. I mean, they're seriously bad ass motors. 90hp from 45ci is impressive.

 

As long as this thread is revived...

3S-GTE is IMO literally a 2JZ on 4 cyls...both square and great to make power out of, but even though I'm a Toyota guy, I'd get the 4G63.

Dodge's 2.5T that was in the Caravan, Shelby Charger, LeBaron, and every other fucking dodge in the late 80s is awesome as well, as is their SRT-4 engine. 1.8T deserves much much respect, especially for the amount of power (let alone torque) that they can easily make. I'm surprised nobody mentioned the Porsche 4...I think it was in the 944 from the 80s? EJ25 also deserves respect, but I'm neither a Subaru nor a flat 4 guy, however you cant go wrong with companies like Volvo, Saab, and Subaru who offers damn near everything they have in a turbo version.

"Honorable mentions": SR20DET. Dont care for the bandwagon when I can get an engine thats already here in an equipped car and IMO better anyways (see Dodge Caravan, DSM, MR-2, Camry, Celica, etc.etc.etc.)
K24. "big block Honda 4", but still a Honda, thus little to no torque. No thanks.

Also, for those who said aluminum sucks for engines with forced induction...see the 1UZ-FE. kthnxbi

 

I was looking for the JFWY in your post and didn't find it anywhere. Were you serious?

 

The guy doesn't even own a car. I think it's implied that any technical post made by him is followed by JFWY, even if not directly stated.

 

Hard to argue with the GSXR-1000. So advanced, so small, so light.

Older than the internet. Look at the van run that RS Camaro!

 

I Believe that the Olds W41 2.3L HO was a beast, 200HP NA and Race versions had varients upwards of 400hp 4cyl. and the 2.5L Suprcharged Varient ! SICK go MantaParts !
