stock for stock, same weight car, power for power, obviously the one with some torque wins.
Mod for mod, a DSM vs even the best 4 cylinder honda(the B18c or the K20), the DSM is gonna win.
Add an intake, exhaust and some other small mods to an Integra or RSX, you get what? 8-18 more hp and 3-10 more lbs/ft/ Do the same with a DSM/Evo/GVR4 or any other good factory turbo car for that matter and you get 35-80 more hp and 50-100 more lbs/ft
add a turbo to a stock K20 or B18c and you can run what safely? 6-10 psi if your tune is very good? Keep the stock turbo on a good turbo car and you can simply up the boost and gain a ton.
Try to run 20-30 psi on a stock internals B18c or K20/24 or D16. You may be able to for a wee bit if your tune is PERFECT and the planets all align. You can do that on a 4g63, RB26dett or 2JZGT3. Probably a few others too, but those ones are proven to be able to do it.
And once you start adding internal parts, its all about the engine builder at that point, not the base engine itself. Tho some hold up better than others do. The 4G, RB and 2J again come to mind.
but again, its not really all about the original at this point. Like domestic guys that say thier 650hp small block "Chev" is a Chevrolet. When in fact its a Keith Black block, Dart heads, Scat crank, Sealed power rings, Clevite bearings, Mahle pistons, Eagle rods, Milodon oil pump, Crower cam, Comp roller cam gears, lifters, pushrods and chain, Moroso oil pan, Edelbrock intake manifold, Lunati roller rockers, and a Dominator carb. The only thing stock is the water pump. Maybe.
We all know you can take the 4g63, 1/2jzgte and Rb26dett and using stock everything but cams, make that same power on pump gas. Or easily on race gas. Hell, John Shepards engine made over 1200hp on the stock block, crank and head. This is pretty much unheard of, up until that time. Off the shelf, Mitsubishi castings/machinings. Yes they were tweaked, but still they are the stock parts, not aftermarket parts. Even now, the only thing that changed there is the Eagle crank I believe.
now, normally aspirated, yes, the BEST Honda stuff is very very good. Up there(but not quite as good as) with BMW, Porsche and a few others such as some of the sport bike engines. Thier basic VE is very good, thier pumping losses are low, they are light weight and rev very well and make good power. Thier manifolds are matched well, they are well tuned in the ECU etc. The do not however, make any torque to speak of in normally aspirated form.
