You have to port a 4g63 head to flow similar to a K series head. Keep in mind the 4g63 was originally introduced in 1976 and the Honda K series in 2001. That’s a 25 year difference in technology.

He’s comparing A low compression engine to a high compression engine more compression mean less boost to make as much power for example a 7.2:1 G54B on 10psi with 54-68mm turbo will make around 230-240 with 310ft. But a 8.2:1 compression G54B with that identical set up on 10psi will make 280-290hp with 370ish Ft of torque. So here is the question what happens when you got from a 4g64 8.5:1 compression to a K24-K20 with roughly 9.7:1 how is that fair of course the lower compression engine is gonna need more boost to make power. Because More boost means more Compression. 🎉

@@dbstherollers8106bone stock k series have repeatedly done 800hp relatively reliably. While the 4g63 is older, that can almost be an advantage, much more time for performance development and it’s the same with the b series. Plain and simple, the k series is engineered better and is more efficient, period. That said, the 4g63 is a fantastic motor and they are awesome in their own right, especially with torque production, and when it was coming out in evos and dsms it was super advanced. The k series is just in its own league, what it can do stock is ridiculous. People make 500hp on stock aluminum block motors with 11/1 compression that were never even designed for forced induction reliably enough to daily. The fastest 1/4 mile on a k series is 5.86 @ 243mph and after 30mins searching, the fastest 4g63 I found was 6.29 @ 229mph both in tube frame rwd cars (I really did try to find a faster time but couldn’t).

People are getting all upset lmao. I watched this entire podcast. Hes a BMW E36 guy. His entire point that he was getting to in this clip was that NA heads generally outflow motors of similar displacement and configuration, that come turbo from the factory. In his case a 1990's BMW inline 6 non M3 motor, from like an E36 325i or 328i. If you have a 500hp 2JZ-GTE, and then this non M3 motor that come NA from the factory with only 192hp and you gave it the same displacement, an identical fuel system and turbo/downpipe setup and the same boost it would likely make 600hp because the head flowd a lot better.

@danyan7 5 ай бұрын

it is not flow, is how it flows. usually 4valve heads had to much flow capacity, for a given displacement and that hurt turbulences and speed. bmw had a good head but small cams, but have good torque, hondas before k, series had good head but no torque but good high rpm flow. 4g63 6bolt has the biggest port and is bad for low performance, and people PORTED more... the result usually was better not because the port, was because was the same bad, other changes made better. k20 head is better than 4g63 head, is common sense. they dont need it, actually not al k series had the same performance head.

@az_3kgt714 5 ай бұрын

and hes not wrong. if you wanna make power NA you HAVE to have good flowing heads. Turbos are just a bandaid for a badly built engine. An optimized NA engine will always make more power at lower boost than a turbo engine. Because the engine flows better.

I completely agree. However, I would check out other brands as well. Overseas they love their Fords. Hondas not so much. My car is an imported MK1 focus RS, there are several of these cars pushing 450 500 hp overseas with little to no issues. No one really knows the capability of the focus block but it’s been proven in America, same block, to hold 700 hp for years.

Someone teach this fellow about compression differences between forced induction engines to naturally aspirated. Also with direct port injection one can have higher compression with forced induction.

I've had both and can easily say the K series can make more power easier,cheaper and more reliable. Had my 4G63 back in late 90s when turbo tech wasn't as good as today but it was 464 at the wheels and was at the threshold of needing everything upgraded and reinforced.

There’s like 20-25 years of design and technology advancements between those two motors.

@xaviercrowley7517 6 ай бұрын

Thing is though. To make say 800 hp, both motors will cost nearly the same with rods, pistons, cams, whatever. However the Honda being open deck, you start need sleeves over 600. Meanwhile stock 4g63 can go to well over 1k on the stock block. Furthermore when you start pushing numbers up around 1k, doesn’t matter what motor you have. It’s still gonna need ported heads. So therefore block strength is far more important than headflow in the long run. Honda head can flow enough for 1500+ hp all it wants. Stock blocks still gonna let go around 1400 and you’ll need a billet block. While There’s a 4g63t that makes 1800 with a stock block.

Engines built specifically for turbos also use lower compression pistons

@alexsaam2696 4 ай бұрын

I was always under the impression that a factory boosted motor is stronger than an NA factory motor cause it's built with the intention of holding boost. Lower compression ratio, thicker block, studded capped mains, better valve train components and better coatings on materials ,etc..... at least that's the theory that I'm going off of for the last 10 years

@jayharris9077 6 ай бұрын

I eprsonally love both engines. Worked with a few K20s, FN2, EP3, FN2, M200 Mugan. But had 0 hands on experience with a 4G63 although, id never say no. But none can replace the rotary. Best engines around 👌

Flow is derived from differential pressure across the entire system. Head flow is only one factor in that equation

Yes . A engine that can perform all motor , once turbo with the right camshaft will perform even better . I’ve been saying this for years . If it sucks without a turbo it’s not that great then . A great motor naturally aspirated will perform great when boosted . 👍🏻

Also high boost on a big turbo at max rpm is all cool with big valves, but on the low end has nothing.

Solution? Porting before boosting, that way you get a easier flow into the manifold

Engines are air pumps. The more air the better. The total mass of “air” in is what we care about. Mass flow rate = density times velocity times area. Head geometry is a constraint on area, and velocity (NA applications), Induction increases velocity Density is covered by air temperature, humidity, and the pressure of the air (NA is at maximum atmospheric, forced induction is anything above atmospheric). So to increase mass flow you need to increase density (temperature, pressure) Increase surface area Or Increase velocity (forced induction or head geometry)

Evo is also putting that power through 4 hubs and a transfer case, each sapping power from the engine.

@markb8467 5 ай бұрын

Dude NA engines have higher compression which is why they make more power than cars turbocharged from the factory and there’s good reason most of them have lower compression.. it’s significantly more reliable long term

Look at the 3800 Series II V6 from GM. Its designed to be relatively efficient for its time. Put boost into it and it turns into a beast!

@conradsealy9603 6 ай бұрын

Most 4 cylinders will make that kind of hp with not much difference in boost pressure. There are SR20DETs at 870hp with a 6466 turbo. The part with N/A designed engines is they usually have much higher compression ratios which is tricky to tune when putting lots of boost into it unless a change to lower compression pistons are used.

This dude doesn’t know what he’s talking bout. Plus he’s leaving out the little tidbits that don’t support his theory like in order to take an engine that isn’t boosted from factory, make it strong enough to handle boost, and not explode on the third pull requires thousands upon thousands of dollars, if not more..

Just give the stats from the tuning sessions is all you have to do. It'll be very clear to show how well intake tract, head flow, and what the air density is comparably. Until people start throwing up actual stats this is all flapping gums.

Honda heads seem to flow way better then most. Even old Honda motors like the F22 have good flowing heads. Honda loves RPMs. For Honda to make the power in the high RPMs they better have a good as flowing head.

Boost is a measure of a restriction. The 4G63 has no problem running 80-110 psi. The K series is not on that level.

The stronger the motor as a naturally aspirated set up, the better It's gonna be with forced induction. NA applications you may need to lower compression (with pistons ,head, head gasket, etc , but your power will be better on vacuum and while on boost but the better peformer as an NA the better when you really start pushing air in and out the engine (air pump)

Well yeah cuz the compression ratio is different. This isn't rocket science. This is even true in old tractor engines. Turbo block vs non turbo. A stock turbo engine is accounting for the boost to keep it reliable

It’s because normally aspirated cars have higher compression ratio isn’t it ? So when you add boost it has more effect?

@jakesteger89 5 ай бұрын

Boost pressure is the pressure that builds up behind the intake valve before it opens..... what is this guy talking about???? All motor engines have higher compression. Of course if you raise compression when your boosted your going to have better volumetric efficiency than an engine designed for turbos.... its for RELIABILITY.
