Sr20ve Neo Vvl

[dareo]

What is this engine? I just saw it online today but no specs are listed. It looks like a n/a variable cam timing SR20. Anybody have any hp/torque/redline information?

[K240]

I wont be of any help to this because i have not ever heard of it. If this engine exzists then i too would like to know some stuff about it.

[spec-u-later]

I t does exist and its pretty bad ***. Low tourque, about 150 and it is rated at 180 horse. there is a turbo version that has 280 horse. Neo vvl na sr motors run about $1900

[s13sr20chris]

neo vvl(not to be confused with regular neo) is very similar to honda vtec. it is actually better.

[240sxin]

so is it better then a stock ka24e, cause that sounds like it might be a nice engine swap.

neo vvl(not to be confused with regular neo) is very similar to honda vtec. it is actually better.

Firstly, Honda was NOT the first to implement variable valve timing; Nissan (via Infiniti) was, atleast to my knowledge...(this has been discussed before here on NICO).

Secondly, ALL S14 and later SR20's have variable valve timing. Nissan used to call it "V.V.T.C.": Variable Valve Timing Control, I believe. They then "upgraded" to "C.V.V.T.C."; the newly added letter standing for "Continuous." This, by all accounts was the exact same thing as its predecessor, simply with a longer name.

Honda's "VTEC" has only 2 stages, or eatleast *had* at the time of VVTC's release. Nissan's version was a triple stage system and thus, inherently "better."

As for Nissan's latest reincarnation of the variable timing, I'm not sure if they somehow improved it and decided to give it a newer, fancier name, or if they just decided to update its nomenclature...

P.S. - As always, seeing as I don't actually work for Nissan, or know everything, I welcome proven corrections so if you know something I've said is wrong, please say so. I get smarter that way.

actually Alfa Romeo was the first to implement variable valve timing called "Cam Phasing" by the auto maker in 1980.

Nissan was second in 1986 using it on the VG30DE and the RB20DE(Skyline).

[240sxin]

so is the engine better then a stock ka24e?

neo vvl(not to be confused with regular neo) is very similar to honda vtec. it is actually better.

it is better because the system works on both intake and exhaust sides.

undeniably

[SeVa-S13]

Bling.Thanks for the info.I still like Ferrari's version though, the whole sliding cam with progressively more aggressive lobes with longer duration and more lift that move with the RPM band. That's just pimp, yet so simple.

[240sxin]

so even thoits i slighlty smaller then the 24 if i get a chance to get one and swap it i should take the chance. I got a freind out here who has the motor, he thinkinf abotu selling it to me for kinda less then what other peoel sell them for. Are the as hard to swap as the sr20det, or are they an easier job seeing there is no tubo and what not, anyways any info on this would greatly help me. thanks guys and take it easy.~Jon

[Supafly]

mechanically i'd imagine it would be easier, not as much crap to plumb and more room to work. wiring i'd think is the same.

If you have a chance to grab that motor at a good price, DO IT. What kind of price are you talking about? Externally(concerned with swapping) they are identical minus the turbo system. Do you know that motor makes 187 hp@7000 rpm

[Onizuka]

there is no such thing as a RWD SR20VE

VE parts are incredibly expensive

It is cheaper to buy a SR20DET than assemble a RWD SR20VE and you get lots more torque and horsepower from the DET.

I know this because i called around and tryed to get parts for this project:RWD SR20DET block (oil squirters)FWD SR20DE pistonsFWD SR20VE headRWD SR20DET TrannyFWD SR20DET GTiR individual throttle bodiesFWD SR16VE cams

Then you are working with a distributer ignition system with the distributer hitting the firewall so you either have to pound in the fire wall or go with aftermarket computer controlled ignition. Then you also need a cam timing controler unless you can figure out how to get the FWD SR20VE ECU you work with this frankinstein motor.

Regardless, i will try this one day in the distant future, it is such a cool idea

The SR20VET (280hp) is AWD and found in the premium trim JDM Xterra, it might be logintudinal but nobody knows if the RWD SR20 transmission will bolt on because the motor is so rare (300 made per year MAX), so new (1999+), and so expensive($8000+ i hear) nobody has gotten their hands on one yet that i know of.

not to mention that a vet is not really any better than a det. thank you for shooting down the idea of just dropping in a ve. i was going to take that liberty myself but i was slow. the sr20ve drops into a b14 sentra easy. its just like replacing the old de with a little bit of wiring. vvl is not a 3 stage system. vvl is 2 stage. vtec is not a 2 stage system. its a 1 stage. ivtec is 2 stage and there is a rare jdm civic with 3 stage. technically you got vtc and cvtc. there is no vvtc in nissan speak. all just minor points. all the vtc types just advance and retard the intake cam.

question:are you sure the rb20de came out with vtc from the get go? i was not aware of that.

[SingleCamSam]

So they use this engine in the Xterra? I'll remember that the next time someone referrs to the KA as a "truck motor" lol. :P

[s13sr20chris]

yeah, thats a funny point. only in japan would a truck be produced with an sr20.

By stages, I meant cam timing profiles. I know what you're saying but it seems somewhat misleading, a single stage variable timing system sounds like just one stage, period. No point where the timing is changed or anything like that, just like a normal engine. Different terming is all.

but also remember it has "280" hp... just like the RB26DETT has "280" hp

about honda Vtec- Their cams have two cam lift and durration profiles, which is seperate from variable valve timing.

s14 and s15 motors just have timing adjusters, the V in SR20VE most probably denots the honda type variable timing AND lift/durration (although it is posible the SR20VE uses a continously adjustable lift controller like ferrari because of the divice right below the dristributer i noticed in pictures)

thats why there is the s15 SR20DE with variable timing and the SR20VE with variable timing and lift. Or at least thats what my findings are.

[Onizuka]

ok i confirmed my belife that the SR20VE does infact use "honda style" variable valve lift cams:

[Onizuka]

ok im a retard, the SR20VE doesnt even have timing adjustment, just variable valve lift

[s13sr20chris]

yeah, the thing by the dist is the 'noid. one solenoid per cam.

[s13sr20chris]

yes i see. you are right. it just sounded like you were wrong.

[Onizuka]

here is a dyno graph of a stock FWD SR20VE with just intake, headers, exaust, and VVL RPMS activation controler.

[240sxin]

Ok so the sr20ve neo vvl is a fwd motor, my friend kinda left that out the bastard lol. Any way thatnks for the info. So what i gather from all thsi is that this motor wouldnt go into my car seein my car is rwd. lol im still kinda confused but o well. thanks agin for the info. take it easy guys.~Jon

[cullenj76]

there is no such thing as a RWD SR20VE

Oops, I just relized that this guy has an S13. I assumed that since he brought up the VE, that he was talking about a sentra or a g20 or something.

[s13sr20chris]

i have seen a rwd ve conversion on the net. suppossed to be one bad autocrosser.

[dareo]

Too bad its FWD only, that would make a pimp SE-R/200sx swap though. If only i had money, an old Sentra, and time... I'd definitly do that, just as a Honda one-upper. Beat them at their own game, FWD/Vtec.

[s13sr20chris]

i have a friend with a b14/sr20ve. he has it all. quaife lsd, lightened flywheel, 20v cams(or were they sr16ven1?), fujisubo header, msd, jwt ecu, and a whole bunch of crap. he is so hardcore he builds his own shocks out of koni parts. i want to say he is at like 189fwhp. redline on his is 8100 i think. thats as high as the ecu would go but the valvetrain could handle more.
