7500rpm Nissan L28 Engine Dyno - 350hp
ฝัง
- เผยแพร่เมื่อ 28 มิ.ย. 2017
- IT’S always impressive when a naturally aspirated engine makes over 100hp per litre, and even more so when it’s using an older-style engine. While we were down at Powerhouse Engines working on my Nissan RB30 turbo build (read about it in the August mag), we saw this stout Datsun L28 motor being run up on the dyno, making around 350hp.

The biggest problem with getting a LOT of horsepower out of the L-series engines is the lack of a cross-flow head. Have the intake and exhaust ports on the same side severely limits port size and flow characteristics. That being said, they did pretty well on this one to get that kind of performance out of it!😉
Most powerfull l28 on stock block is 1100hp
Is it possible to make a new header with cross flow? Or would that not work?
@@C0astDelta In that case, you'd be pretty much stepping up to the R-series inline 6. (Twin-cam crossflow heads) i.e. R32, R34 etc. The L-series just are what they are, and they're super reliable as L6's go. If you want big horsepower and a more efficient combustion chamber design, then the R-series are the ticket. ;)
@@danw1955 ohhhh, sorry I've been mostly a car nerd on the surface level. Learning about more details has kinda avoided me but that's really cool.
You can actually make nice power and BMEP with that design, it's just more difficult to get better high RPM performance. The main thing I don't like about this design is assembling it since everything is bunched up on one side. Listen to it though. That sounds great!
takes me back to my younger days. The good old L series Datsun 6 cylinder always had a nice note to it. cheers For the upload Street Machine
Me too. The L series are also very very hard to kill. They can take a monster thrashing - they love running hot and will do so all day every day. Great motor.
Then i guess you may love this: th-cam.com/video/Eo0cF9qYZek/w-d-xo.html
Probably recorded an NA for the anime yet still sounds SO GOOOD!
@@TheMrVicistPractically speaking L engines is very old and for modern standard at least also very hard to modify beyond 500 on a stock displacement that is why most L28 runs stroker kit of at least 3L or more and afaik the biggest stroker was 3.1L
More than 80 lb/ft of torque per liter on an old 2-valve reverse flow head? Pretty amazing... would love to know what compression ratio and headwork has been done!
Sounds like my neighbor trying to spin a rod bearing every morning at 6am...
Lmao that is funny, I had a neighbor that was the same way, he’d jump in his 77’ Nova and floor that SOB ice cold, I mean the car was rockin 😂
Oh my god a dyno operator that uses a step test instead of accel. top man..
My L series is currently with Les for a rebuild - it couldn't be in better hands!
Great video Street Machine!
Thanks for keeping the music down so we could hear the motor
Wow, that sounds so amazing. It sounds like it wants to never stop running…
Someone's watched Wangan Midnight
@@1mawesomel1kethatIn all seriousness though this engine has that typical reliable old school loud mechanical sound to it and indeed probably runs forever.
Anybody else just giggle and admire the beauty of old school engines? Just me? Ok
You're not the only one
Miggys' Garage : old school is just what the New School Re-Heat and try to Repeat. They've been Beat....
Ooh was that an intake backfire at 0:23?
Glad to see people still building these, the RB swap seems to be the go to option for older Nissan/Datsun cars.
Relatively cheap and Easy power from the later model Twin Cam crossflow designs in comparison.
Kind of like building a GMH 304 vrs a LSx
guyver33 bullshit go get a fj20et everyone has done the rb and its boring as fuck
RB30DE is not that good for NA if you look at Rocky Auto did a 3 litre bored out to 3.2 but only makes 300hp ate. 2 valve heads if done well can swirl much more centered in the cylinder than tumble and roll 4 v heads.
@@Itsuptoyouandme yup but the RB30 can go up too 3.4L
What limits it from going past 7200 Rpm tho the raised deck?
Wangan midnight anyone no just me jk cool engine tho
You mean the l28 custom twin turbo bored to 3.1L all stock parts except the crank shafts with old td0 ball-bearing turbo's
@@johnyoxley4715 Hey, if you're into Wangan, then we just finished translating chapter 48. We'll be posting the new chapters in the Wangan Midnight Reddit section and also in the MF Ghost discord. Here's the direct link imgur.com/a/OPPeUbc
Johny Oxley The crankshaft is about the one thing you could leave stock in an l28 making 600+ hp. It’s the complete opposite.
Sounds just like the anime
sounds like it.
This chain driven engine doesnt have my RB25ETs belt driven harmonics nor the awfull small six Triumph 2500 drone. The first Datsun six Ive come to respect. I really hate narrow bore spacing engines, the Toyota in line JZs and L's and RBs. Ive had a great run with my LD28s and RB25's but only this one has the sound I like. Les, you rock the Red Centre. Looks like an LD28 crank got put to good use. And the 350 hp at just 7000 rpm from a 3.4 litre....Nice one Australia!
that extra 500 rpm makes a nice sound try another 500 ;)
Done it in my stock l28 a few times
PurpleZ for how long ??
Very cool
Have a look at "the green hornet the joy of driving"to see one of these motors in a Datsun 240Z
I think thats the torquiest sounding L series but not the best, the best sounding L28 singing at 8200rpm is again another level. The best sounding L series where BRE 510 L16 raced in the 70s
That exhaust note is pure art.
I don’t even hear the exhaust over the intake noise and mechanical noise. Love it.
My first car was a datsun which had this engine ...i really missed it
Guy in Calif. 7 yrs ago that built One up to 3.3 & got 367 h.p. & Was if Featured Car of a Show There @ that Time
What rating octane number (RON) is?? And what number compression ratio?
A straight 6 does not have the power/weight of a V8 because of the heavier block and crankshaft but for silky smooth vibrationless torque it is unbeatable.
Its really hard to tell by the angle of the video but it looks like the third throttle body is not opening at the same rate as the first. Just an observation from what is visible from the video.
Are the individual throttle bodies worth the investment? Can't decide!
precrossflow goodness!!!
Reverse flow head.
A r c h e t y p e ☆ D a t s u n what model head was used ??
the voice of the Devil Z
Good old l series with sidedraughts sounds good
This is fuel injected
A mate used to embarrass plenty of V8s in his standard 240k 2 door.
Fuck yea some jdm love from my favorite engine 😎
JDM?! Thing is the L28 was mainly for export as Japan had a large car tax for anything over 2 litres in displacement! Lol!
chris henderson yup thats why the L28ET wasn’t allowed there it would kick serious ass if it did stay
@@chrishenderson5094 yeah even the l24 and l26 were export engines iirc, what the fairlady z had was the l20
where is the vids on the car that this motor is in
nice
wait...is this on the N42/N47? SHEEEESHHH
Lmao what kinda pulls are these 😂
I want that in my mq patrol...
That was a weird way to dyno an engine, I wonder why the prolonged loading like that? Usually you rev it all the way through under a predetermined load and shut it down
Daniel Brealey they were running step tests, but because we couldn't hang around for the full dynotest we didn't get everything
Fair enough, they weren't doing power runs when you were there- I understand now. Cheers... ;)
Step test gives you a far better reading off the dyno allows the motor to settle..accel test can vary big time.
I've got an L28 in my Datsun 260Z 2+2 auto. It came with the engine 25 years ago when I first bought it. I think getting it built up like this would cost a pretty penny though. I wonder if it would be worth doing it as a mild stroker 300 Hp would be plenty for me
no its a 2+2
thats awesome my grandad owns the exact same setup 260z 2+2 but hes the one who swapped the l28 into it with his best mate harry bargwanna whos sons jason bargwanna use to be the driver for the valvoline v8 supercar team, anyway hes had it for something like 35+years as his daily driver aswell as taking it to the track every second weekend for super sprints so it will be worth doing it even if you dont have 300hp there a great car hahaha
Im curious to know how reliable are those built engines. I know they’re tough in the stock form, but not modified like this.
The green hornet has been running around Leguna Seca for about 6 years+ now without any issues.
Rebuild any engine is a risky adventure. Its either gonna run great or fail catastrophically. The more you push its limits the more risk ya take with modifying it beyond designed capabilities. But that's all in how well you desigmed to engine to handle more power and the problems that come out from that. The cooling system is where not where ya wanna get cheap. Air flow is horrific on the z cars. 14ft engine bay and the front radiator cowling is too low. Washes all the air out the back under the car and not up. That's why the L28 series had a cooling fan that would turn on as ya walked away. So it doesnt burst into flames and shit. Bigger fuel pump, better breaks to wanna be able to stop 2.5 tons of fun. Dont forget that. Harder shocks in the rear with a higher booty is preferred. Engine had a lot of torque and slaming the rear end into ground will happen in not addressed right. Bigger wheels and tires. 17 in wheels max. A good exhaust. I had a set of monza headers and exhaust and it sounded mean. Has a great deep roar ya dont hear many have. Sound more motorbike tone to me. Not a fan. Deep sound and would bang flames out the back gearing to a stop. Loved it0
look at what 2 valves per cylinder can do !!
pec1739 much better torque curve then a 4 Valve
that squeaky noise is the blow off
What's more impressive is I'm making that naturally.
Cooling it will be the issue on that engine. Shit skyrocketed at the end of that last pull. Air flow in the engine bay was never great on any model z car. Finally added hood vent on the S30 in 1980. Fuel injector hose would bake to shit first. Took me all damn day to change out mine. 8hrs to not catch fire was a win though.
Key thing with a engine like this is to add a nice large radiator, good oil cooler, electric fans, 1977 era 280z hood with vents, lots of heatshielding, and wide front valance air dam to help direct air through radiator/oil cooler. I have a stock 280z and just changing the radiator out to a larger aluminum radiator with more rows made a huge difference to where my temp guage sets. Heat was definitely a weakness on these cars but rust was far worse. It's really a shame because most L series engines out lived the car they were in.
Music.🎶🎼👌🏻👍🏻😎
Is that a diesel l28 block to get that displacement. I don't think it's possible in a regular l28 block... maybe with custom cylinder bores.
all the boost yea it is with a custom crank.
Liners
良いね！
Who is running that dyno? It needs more load bad
Why does it have no torque?
where is the fj20et
13 to 1 compression and oxygenated fuel.
Acá en Argentina giran a 9000rpm
That's at the normal max displayed rpm
Would it be possible to get an L28 to say 600-650 hp?
@@arinb.756 I have made a discovery. Someone has done it before, specifically the car made around 680 HP. From what I can tell it seemed to be a topspeed vehicle a nissan 240z specifically the S130
How the hell do you bore out to 3.3L? Aren't the cylinder walls too thin?
They test alot of blocks
Ever seen much gains with an EFI system over carbs for tuning?
I remember L28 builders running the diesel crank for a similar capacity.
Custom crank can get you there too. You can even use a LD28 block to get 3.5L with a custom crank seen one make shy of 400hp on triple carbs.
@@austinanthony4016 its fuel injection
Please build me one
What was that flash in the throttle body at 0:24 caused by?
backfired through the throttle body
YeS
@czeromedia
Would Blow a 202 into the weeds! Lol!
When your throttle gets stuck thats what it sounds like
Hahahahaha, it’s funny cause it’s true
L28 350hp Devil Z
Actually L28 350hp Demi-Devil Z. Fully Devil Z is when L28 has 600hp
3.4L！
sounds like a 4A-ge but with a growl
and 2 more cylinders
Thats how ITB sounds like,the longer the length of the trumpet,the more it sounds like that,shorter ones sound like snouting.
The length of the ITB also affect Air velocity so it also affect Torque output from certain RPM.
How much would a complete L28 engine cost? Wires and everything? Noob here. Sorry.
$45k
STREETMACHINETV 45k in pesos? Wow!!! Thank you for the input...
More like 5 grand only engine then you need all the other components like spark fuel ect
the l's go way better with a OS Giken twin cam head but there rare as fuck and expensive if you can find one
OS Giken TC24-B1 twin cam
Inexcess of 30k USD if you can find one.
The reason for that price tag is to cover the cost of research and development that went into engineering the head. Because they are not mass manufactured the cost of production is even higher. You must also take in account the profit profit margin that must be gained to justify the development of such a product. So as you can see the car aftermarket is all about supply and demand. Don't be mad, its strictly business.
@@Bruceillest101 I get that... last I read they are doing a new run of heads, but you need to buy a complete engine from them and they build it, but it's 90k. I get the whole paying for R&D but what's the point if only 7 people will buy your engine package. Not really making your money back. If they made those heads and sold them for 5-6k or so, I'd wager money, that in the long run they make more profit cause they would sell alot more.
Is it possible to reach 700-800hp because definitely if you put it back to 240z it can reach around 220-250mph
You watch too much Anime.
With nitrous at least 300 m.p.h.
Go back to school please.
I hit 200km in mine and that's enough, it's a momentum car not a 0-60 killer.
220mph would require about 670bhp and 250 would require about 985hp assuming you're on thin tires and your car is more aerodynamic than the stock car. I could list off a hundred different cars that would be better suited for that speed and would require less power to do it too
has a slight miss and quite a few flat spots you would think they would tune out
awesome... but it's technically not really an L28 anymore if the displacement increased...
@Jorge Castro well... in the spec rundown it says 3385cc so it's likely been bored and maybe stroked... which is why I said it's not technically a L28 anymore... L34 would be correct but I suppose that might throw off people who are both new and old to Datsun/Nissan L engines... a newcomer might think there's a factory L34 and a familiar might think it's bullshit because a factory L35 never existed...
@@beautythebeard4935 I'd love a 240 myself... but... I think I'd go with the O.S. Giken TC24-B1 head on the L series block if I could have that dream come true... lots more power potential there...
@@zeroswings2 Technically a L3385
@@arinb.756 I don't think finding one is as much of an issue as I think O.S. Giken can and does still make them... it costs about 20k though... so paying for one is the problem... also as I said, it's a dream... a wish... I won't say it'll never happen just that's it's not exactly likely to...
クロスフロー化したらどうなることやら・・・
Lsx with same money invested probably make double
Yeah, but it's double the capacity......
You're a pelican, mate. Go home.
@@72mardy Of course its bigger but it takes up less space and you can have the majority of the engine behind the front crossmember. Never been called a pelican mate but whatever floats your boat.
This is a 45k engine. It's built probably to compete in a specific class of racing. No one builds a L28 going for bang for buck. They are expensive for not much performance. It the way she goes.
Hp are high, but rpm are low
Mine revs higher then that with junkyard parts.
