SR20VE vs SR20DET: Which One is Better? 

If you guys enjoyed the video, please SMASH THAT LIKE BUTTON. It helps the channel out a huge amount and helps RU-vid put the video in front of more people. Thanks for watching 😬

Give us a full SR engine family breakdown

In South Africa we have more front wheel drive applications and a lot of guys here drag race them in Sentra's and i must say the VE is in the lime lite making good n/a power. We have a few det applications mostly used for daily cars. We have a saying in south africa in our native tongue "VVL is baas" translates to " VVL is king"

I'd love to see a video of the whole SR family

The SR16VE also had the highest hp per liter of any production car at one time.

Thaaank you this video helped me alot cause I wanna build a SR20VE 🇿🇦🇿🇦🇿🇦🇿🇦 I know a guy in SA he have a SR20VE engine with over KW220+ & he ran 11.3 over a 1/4 mile.

Keen for the sr family video mate, tanks for the upload.

many ppl prob didnt know there is an actual SR20VET engine which is only found in the 2001-2014 Nissan X-Trail GT The engine itself is a axial engine coupled on a AWD automatic transmission ( never done in manual ). Many parts differ in shape and function compared to the VE. One of the most important things are the VVL solenoid. This version only have variable valve lift on the intake cam. And the solenoid position is really more practical due to the angle mounting position, this add more clearance for any kind of transplantation of the engine to an other model of chassis. The injection system differ than the other version of SR20. This system is top feed styled and operate high independence solenoid. Normally Nissan using low independence injector in most of the top feed setup, like in the pulsar GTi-R. The injectors used on the VET are high independence and the possible volume provided by them is 444cc at 3bar. The exhaust manifold on the particular model is really better designed for maximum velocity. The shape of the runners are really more like it should be to get more speed of the post combustion gas. But ! There is a big but, Nissan engineers made several notch to the runners to get clearance for the bolts, big notch. For example, the first cylinder exhaust port is reduced the way that we can’t enter a finder in the manifold. This will cause a resistance that increasing back pressure on only one cylinder and a lot flow distortion at full boost. The ports have a mismatch about 4mm on the exterior side of the cylinder 1 and 4, like the manifold stretch back. That’s a lot of handicap for a “performance” engine. The exhaust ports have the same pattern than all the SR20’s manifold, that’s good for performance mods and engine adaptation on an other chassis. In this particular case, we try to install an S13 bottom mount OEM manifold. We can also think about using flanges to design custom manifold. The intake manifold is really more efficient than DE & DET versions. The intake have shapes inside to improving air flow and velocity without creating any turbulence. The aluminum cast is really high quality, that make modification and welding much easy to do. The intake plenum itself is really more higher than all the other version of the D’s, making engine swaps a little bit more difficult, because the VE & VET intake manifolds have a different pattern and port shape than the other SR20. Both VE and VET have normally the same pattern. In this case, we try to simply turn the intake plenum entry from right to left. But the two middle ports are a little offset and make the operation impossible. So we scan the ports, to get a perfect match on the computer and designing our own velocity stack to weld directly to the OEM runners. The runner length stay the same but we add a little more length to improve the flow by adding velocity cones. We also create a simple plenum that pointing the throttle a little to the ground to help future clearance issues and possibly help the air flow inside the plenum itself. The throttle body of the VET is drive by an electronic motor, the servo motor system generally add pedal lag and are not specially effective and cost more to adapt in performance application. So we install a S13 Sr20DET throttle body that is drive by cable. The Turbocharger on this engine is not advanced as the Gt28 with ball bearing found on S15 version SR20DET. This engine only have a bushing bearing and the trim is really small compared to the HP produced. Many source affirm that the turbo used on the VET is a special billet wheel GT28 with ball bearings but this is absolutely false. The model used to pressurize the VET is a non-common version of the GT25. This turbo is generally designed to produce between 170 to 270 HP on 1.4L to 2.2L engines. The entire routing of the piping is really well done, the piping have good size transition before the turbo to improving high velocity. Smooth curves, improved for best flow intercooler and the throttle body right after the outlet of it, making this engine near lag free and using the most percents of efficiency as possible. The inlet flange of the turbine hosing is a normal T25 pattern, but the outlet pattern is not the same as normally found GT25. The flange shape is the same but using different pattern, possibly because of the catalytic converter bolted directly on the turbo that required more space than a regular downpipe. The turbo exact model is GT2560S. This can be ordered with the new revision Garrett part number ( 715643-5002S ), previous version are ( 715643-0001, 715643-0002 ). Or at Nissan directly with this number ( 14411-8H601 ). This particular engine using coil on plugs like most of the SR20 but only identical as the S14 and S15 and have specific spark plugs. These are produce by NGK but are not available outside Nissan. 3 model of spark plug are available, the difference is the temperature. By default Nissan used the PLFR6A-9 ( 22401-8H616 ) but they have a hotter version PLFR5A-9 ( 22401-8H617 ) and a colder version PLFR7A-9 ( 22401-8H615 ). You can order them normally at Nissan, they will order them from Japan. VVL, what that mean? its simply the abbreviation of variable valve lift. The VET have a special cylinder head ( number 8H6 ), its a little different than a P12 head because only one cam is variable, there is a big difference between lobes. The smallest have 5mm and the VVL lobs have 6.75mm this is really big, about 26% lift difference. The exhaust cams get 6.5mm lobs. The cams do not directly push the valves, there is rockers that will change the valve travel. The intake valve movement is 8.5mm on the base lobes and get 10.15mm on the bigger lobes. The exhaust always have 11.5mm. ( these values can need to be re-done a second time to be sure ) The compression ratio is normally 9.0:1

You got most of it right and I enjoyed your video, long block against long block, the VE wins hands down, and is the pinnacle of what Nissan was able to do with that platform at the end of it’s lifespan. Huge improvements from the oil pump, all the way to the dual valve springs.

Very informative. Thank you. Keep it up

Yeah please do a full video of SR family. I live in Costa rica and see silvia’s and sr20’s with VVL all the time ! I want a Silvia but it has been hard to find specific info on all these different engines, which cars they come in, etc. Thank you for the vids and info 👌🏼

The sr16ve has comparable compression to sr20ve (as far as I'm aware), the 11:1 motor is the sr20ve "20v" (though still 16 valve, slightly misleading) from the P12 Primera. The sr16ve in the N1 Pulsar has more understandably.

i enjoy a lot ur videos pls in the future talk about the toyota 2gsre family

I'd love to see a whole SR family video.

Nice video. The VE ALSO has piston oil squirters.

Nice shirt 🤘👌 I have an SR20DET in my S15, there's an SR20VET conversion that costs about £6000 😂 I'd love it because neo VVL is amazing but it's so expensive to do!

Cool video! But I was hoping that you would go into more details; sodium filled exhaust valves on the DET, individual coil packs VS dizy. GTi-R is the best block, it's a 54C block which was used in all of Nissan racing cars that were FWD based; so Primera BTCC, RNN14 used in WRC. 54C block was teamed up with a mechanical lifter head, oil cooler, even lower compression ratio with stronger pistons and rods. It had ITBs from the factory, 444cc injectors (370s on other DET) and a T28 turbo feeding a very large intercooler that was top mounted. Oil pump and timing cover was different on the 54C as was the crank and even the rod bearings. 500whp has been done a few times with this engine without any internal work. I built many of these engines in the 90s, they are great with one major flaw, lubrication system sucks: rod bearings go bad often (even on the 54Cs).

I have a boosted Sr20ve making 452hp stock motor just boltons and I never had a problem with it

I have a SR20det in my Ke55 Corolla

Great Video 👍... please , compare SR20VET vs SR20VE... thnks.

Super informative video💯 do you know alot about Toyata 3sge Beams blacktop and the 3sgte?

VE has oil squirters too 😊. Nice video👍

Sr16ve and sr16ve n1 has a better flowing cylinder head and larger cams than the sr20ve. So use the blue top sr16ve head instead. Its better than the black top sr20ve for those thinking to a conversion, great video. You can still order the oem sr16ve red top n1 intake, as it has two provisions on the intake for two injectors per port. This = 8 injectors for a 1.6 engine. It also has the same size throttle body as the black top sr20ve and has a higher 11.7 compression ratio. It will cost you, but you can still order the oem parts for the ve range.

Thanks for the fence ride..

The SR20VE 20V from the P12 has 11:1 or 11.5:1 ratio I forget but has only one trigger for the intake and exhaust cams that open up at 5000rpm vs the P11's 4500+/-rpm for the intake and 5000+/- for the exhaust. Again, I forget the exact figures,

i have nissan primera p11 -144 sr20de nice car and engine sr20 power :( The SR engines are powerful, even if slightly modified, to compete with the V8 cars

The new trend is to swap the SR20DET head for the SR20VE head on the SR20DET blocks.

The SR20VE also came with piston skitters.. some people doing a just a head swap inestimable how much more oil the VE flowed.. not just for activation also for rocker lubrication and having 50% more oiling pipe holes for the additional cam lobes lubrication

In the block, the SR20DET piston skirt oil squirters are more important than you think, especially in turbocharged applications due to higher heat and expansion properties. The oil not only lubricates but keeps the skirts cooler. Mitsubishi retained the oil squirters in their 4G63T Evo engines for a reason and quickly stopped using their non oil squirter blocks in turbo applications.

Should do a video comparing transmissions. Nv4500 vs ZF5, NV5600 VS G56 etc

VE was also used in the X-trail and came in 4wd. and a limited run of VET's in the xtrail too 6,389 built. SR16VE was used in the vzr 197hp in the n1.

Need to see a video of the vet

yeay that bluebird on 01:20 is my car thank you 😊

I’d love to see the difference between a Roller rocket SR and a non roller rocker, what are their advantages and disadvantages

South Africa loves Sr20 VE , my next car is a Nissan Sentra 20VE add N1 cams from the sr16 and you have a beast

Tks for your video. My son is busy building VE head onto a DET SR20 block. Forging internals and he is going to run a spitronics management system in his S13. Going to run 444cc injectors for now with a GT2871 Turbo. Plan to to replace the injectors for 1000cc units later on. Everything is seriously expensive in South Africa so it is a lengthly project but we are both looking forward to getting it to run again. Incidentally, I just purchased a S13 chassis myself and we putting a 2JZ motor into that one. Looking forward to putting the two cars against each other to see which is faster around the track here in Port Elizabeth. Kind regards

Yes all engines pls

Hard to compare apples to oranges.....🤷 Closer comparison would be ve vs de. Vet vs det

Both were also used in all wheel drive applications

Need the full SR family

I am seriously thinking about doing an engine swap with one of these into my 1985 Nissan 720 4x4. I bet it would be awesome!

You can do a vvl swap in a rwd car with a lil custom work. Jimmy is doing one now in his s15. Not an Sr but a fwd k20.

The VE was also used in a sabre gxi200 as well as the sti200 Sentra

One thing that i have seen here a lot in costa rica is FWD sentra’s with sr20 VVL turbo and they RIPPPP and the sound of VVL destroys the sound of VTEC. But i think a well modified sr20det RWD is a beast also. Would be a good match. Thanks for the info again

Bit of an odd combination. VE normally for NA swaps into FWD and DET for turbo. Many builds with these engines are Frankenstein builds with different head/bottom end combinations. The SR16 is also part of this family and commonly part of SR20VE Frankenstein build. May be part of the reason for confusion

How do you know this much about these engines? I used to make them in Nissan UK, I was project leader installing the production line, I honestly dont know that much!

do a video on the the whole sr20 engine family

Was waiting for the sr20 family video but I'll ask my question anyway, how much horsepower can the sr20vet safely handle on stock internals? Also, can the stock turbo reach the maximum horsepower capacity of the engine?

Hey, can you please do a detailed video on the sr20vet. The internet is filled with information on all other SRs however I can't seem to find much about the SR20VET.

I’m for the sr20ve 100% mine has n1 cams dyno 205hp

Where I live no primera got the sr20ve they all got the det from factory making just under 300hp

how is a combined det block with ve head suppose to be better than an all out sr20 det or all out sr20 ve? what does it give the other oem ones cannot?

Please do a Video of the entire SR family! . And preferably the cars they were used in, please . Back in Highschool, myself and my closest friends were and still are very much into Japanese cars, especially the late 80's , 90's and early 00's era . Some were Toyota and Honda fans but i was With Nissan all the way . And the topic of Variable valve timing and lift came up often in our Debates/conversations and the economic 2.0L or 1.8L cars they were implemented in, and which manufacturer did VVTL better . And i can tell you i defended the SR20 till I was red in the face (since i was the only one who was Fore Nissan, since all my cousins owned, raced and dailyed nissan Sentra's 200sti's and Sabre 200gxi's so basically Nissan Ecology Oriented VVL)so i saw first hand the competition they raced . im from South Africa where this engine is Infamous to some and Notorious to all I didnt even watch the video yet haha, i deleted so much out of this comment just to keep it Short enough to have enough of the important bits i wanted to say, i still have alot to ask and say though. But hopefully watching the video will answer them .im a car enthusiast you can say, But Nissan is my team and i want to know more about the SR family and preferably the Cars they were used in. And thanks alot for this Video and thank you for this Channel!. i'd usually have to do major research but this channel(you) explains things very easily to understand and end up learning more . So Thank you again

Were any of these engines used in production like in the sentra, altima, rogue's juke etc... or are these similar to the VC turbos they have now?

Excellent

Hey ..Good job..but wat is d difference in up an down draft

Full details on the SR family please 🙏🏾

So can I run a DET head on the VE if I wanted to. and will the VE take a DET turbo manifold no problem. Also will the VE be able to use the RWD transmissions from the S chassis cars?

I WANNA SEE EVERY SR ENGINES! - i'm buidling Multiple Build

hello guys from me too.your video is very nice.congratulations.I would like to ask a question.can i put in sr20 gtir turbo block, head from sr20 rr (roller rocker)? and put the pistons from rr in gtir

Vote for video on SR20 family

It makes more sense to compare a turbo motor to another turbo motor. Vet vs det

First of all, nice shirt!

Please compare All the Sr motors

Can u do one on the sr20 family plzz dustin

Do a video comparing the Toyota 3SGTE and the Nissan sr20DET

Explain the difference between the sr20 de and sr20 ve and which one is better

SR16ve has 11.0:1 ratio the Sr16ve-n1 has 12.5:1 or even 13.4:1 ratio. The sr20ve gets the 10.3:1 but if you swap to n1 cams you'll get the 11.0:1 ratio....

there was actually a factory sr20vet. very rare. came in the JDM Xtrail GT

Great presentation. Im looking at a SR20DET wondering if it will fit in my petrol 2005 X-trail. But an overhauled one here in norway is 3500$ so Id have to ve pretty certain. But as far as I know the x-trail gt had a sr20det. But was it the same automatic transmission and sp forth. So many questions.

I'd like to hear about the entire sr20 family for sure, everyone talks about VE and DET , although there is a huge amount of basic sr20 engines that are dirty cheap, I really want to know if they worth a build

Hey could you find a get a the best meckanick that you know to combind those 2 engines that you said in the vedio for me

Hi.. I have a g35S 2008.. 6 speed manu.. Engine broken..i want changed by one more fuel economy .. If you have an idea what is the best in nissan engine can be work with the 6 speed greabox Thank you Thank y

Bck in like 2000 a friend of mine tried well not tried but did an SR20DET from an s15 into an nx2000. It was alright but because programmable ECU was rare couldnt really tune. But he recommended never to do that swap lol

I’m gonna check out a 99 Sentra with a sr20 2.0 5sd and 170000, it 2 1/2 headers and a 2 1/4 tubing muffler, they’re asking $1450 and I think if anything the motor should be worth the price

do you know anything about Haltech and how to install a pro harness with ECU

Do the video on the sr20vet

Can you do one on the 16v opel kadett superboss engine please?

11,2:1 is a sr20de with ve head, common in primera tunes. 10,3:1 is a p11 sr20ve, and 11:1 is the p12 sr20ve 20v

Please clarify which engine was used for rear wheel drive cars ?

Hello bro, I have a nissan sunny b14 engineer ga13ds 1295cc carburetor... I want to swap an sr16ve in my nissan b14..... Can you tell me what modification needed to do ?? Or i dont have to change anything ? Can you help me please bro ? Before i buy the engine i thought to better ask first...

What about the SR20VET that came in the nissan X-Trail

Im currently rebuilding my 1991 sentra SER... it has a high port SR20DE tho lol

Price compare of the two engines pls

How About VET what came in the xtrail GT

can i use SR20DET Crank Camshaft Position Angle Sensor Distributor on a sr20de?

What is the difference between the sti and the gxi which is first

SR20VE also has oil squirters.

Sr20vet is definitely better, I'm in process of building one right now

Im only 18 but when im old enough and have money i want a nissan primera p10 eGT like my dad but not witg 150ps sr20DE i would love to put the 200ps sr20ve from the primera p12 in it

VE YES!!!!!! primera

The RB30DDTT is a direct injection engine, symbolized by the D’s in the name. Is the SR20DET also a direct injection engine?

Make a video vet vs det

So can i replace SR20VET cylinder head with SR20VE?

Personally sr20ve is badasss the lift on that things 😍

The answer is SR20VET. Such a pity Nissan limited the production of that glorious engine so much

Can i put a SER 20 in a 1995 Hyundai Accent

How hard would this be to drop in to a newer altima

What of Garebox I can use on my nissan sentra

2.0L de vs 2.0l na(first comparison) 2.0L de-with itbs 2.0L ve-with itbs(second comparion) daily race motor,which is better?
