RB VS L

[RBZ 260]

we hijacked some poor guys post trying to sell his wheels.

 

http://www.viczcar.com/forum/index.php/topic,6954.0.html

 

Stevo got us back in line but some of us feel the need to rant  so here it is.

 

 

as topic said RB vs L series engines.

 

RB= Race Breed 

L= ??

 

obviously technicaly the RB is superior to L in many ways so how can L be the "real" engine? 

( running for cover behind the rest of the owners with RB powered Z should be few )

RB= Race Breed

Please don't tell us that you think RB actually stands for 'race breed'.

 

I would put put an RB in a zed no problems. Ls have a special slightly spongy place in my heart tho 

[RBZ 260]

RE: RB=race breed

LOL i know it doesnt stand for that but bit of $hit stir. 

 

i only came accros it the other day and laughed but hey looks good so i thought i chuck it in.

 

personaly RB is the younger brother to L.  obviously newer design with few improvemnts. as a standard engine its pretty good and proven very reliable. also responds to mods quite well.

 

though my favourite nissan engine is the VH45DE and SR20DET for their design all alloy decent tourque etc....

 

owned few RBs and been pleasure to own. though love to get my hands on RB26DETT that be my dream Z engine.

 

though i respect the Ls too. had one running  L28 on 5cyl with dodgey tune and still made the z move very quick.but it also sounded so damn good (once the 6th cylinder decided to join in the band)

 

but being a bit of a power freak cant go pass the RB cheap to buy and modify.

Yeah, Horses for courses. If all out power is your aim then RBs are an option (Not the only option). 

 

My reasons for staying with the L are:

1. That sound. Way better than an RB!!!

2. I own 2 L powered cars so I can swap bits if something dies.

3. There was no conversion required and it retains some of the lineage of the car.

4. Simplicity, I am no mechanic so simplicity is important.

Oh Gowd, here we go...

[PZG302]

For mine, I run the L series as I have to to comply with the rules for 2B marque Sports cars to run at race meetings for CAMS and AASA to run in Production Sports Cars, otherwise I would have a ROTORY sitting in the engine bay Now runs and hides!!!!!!

[NZeder]

otherwise I would have a ROTORY sitting in the engine bay Now runs and hides!!!!!!

yes a R26B aka quad rota

[reverendzed]

I don't mean to get all technical on everyone BUT 'L' for me stands for LAZY!, it's already in there and drives me fast enough to get a speeding ticket...so RB to me stands for 'too much bother'!

[bluerat]

Ripper!!

 

Twin cam modern engine horsepower is easy, and expected. Getting grunt out of a single cam lump from the late 60's, well thats cool and un-expected. Theres nothing better than rounding up some twit with all the bell's and whistles in your old school grunter, simple as that. Plus all the classes and event's I want to run you can only use an L series. If you want a Skyline motor, buy a Skyline...

 

Plus I have never seen a powerfull N/A RB? but I'm sure NZeder will prove me wrong there!!

 

Catch ya,

Funny thing is, I've been bitten by the rotary bug myself .

 

Just listen to this sound, brap brap brap.

20B would be enough for me lol.

 

Honestly though the old L-series is a cool motor, if you want big HP numbers go RB. If you want the experience of an old school 60's / 70's sport car stick with the L-engine.

1986-1988 Hr31 Skylines came out with an RB20e, RB20eT, RB20DET and there was the M30, made by Tommy Kaira which had an RB30 bottom end and RB20 Head, NA it made 170kw back then. 

 

I am about to buy my first Zed and am currently weighing up L28eT vs an RB conversion.  Know alot about RB's - not alot about L series.  Got research to do.

[sco_aus]

Ls are cool for the old school feel, rotors are something for very different category (but lots of revs dont = lots of power), but RBs have the torque/power and the relative ease of installation, plus with the Nissan heritage and still remain relatively rare, i'm glad I made my decision...

[Quandary]

The L series was already old before they stopped making them but it meant it had 10 odd years of mods and upgrades to get the most out of them before a more powerful factory Jap engine was made.

 

And I think it's a bit silly that some debate about what engine they want when they don't have a Z yet?  At least drive the L series Z for awhile first and appreciate it.  You're kidding yourself if you think its going to be underpowered.

 

I don't think I could personally stray from the L series until I had a few more Z's to play with. :-\

[sco_aus]

Its under powered after pulling 300rwkw from an RB25 is the point... The L is a great engine for its day, but when you can hit 100km/h in a few seconds with an RB, I'm sorry, but they don't compare.  On the other hand, Ls are great engines, lots a N/A torque for their time and I love them, but its sooo much more work to get less power than an RB...

[ScottyB]

Silly?  I have had VG30DETT, RB30e+t, RB20DET, RB25DET and other powered cars.  I do believe in comparison a standard L28 will feel slow.  I said I am doing some more research and agree that I have no idea how an l series NA drives because I don't have one yet.  But as with what sco_aus has said, coming from 180rwkw-250rwkw RB or VG eninges, it's pretty easy to follow that I would want that in my zed.

Who knows - I might hear the sound and want to stick with an L series.  Skyline nuts (like I have always been) will tell you how good an RB sounds also.

as topic said RB vs L series engines.

 

RB= Race Breed

Round my way RB stands for Run Bearing. Personally I think if you're not going to keep an L-series then you might as well go to a 1JZ engine (like I did) which is cheaper, much stronger internally, more powerful and much more torquey in standard form.

[sco_aus]

And a heathen Toyota engine , nah they are a great engine, would do a 2J if i had my time again.

[luvemfast]

'L' for me stands for LAZY!

I know that when I think of lazy, you're top of the list Dave 

I mean seriously, how long does it take to restore a car........ c'mon man its been a few weeks, hurry up!

 

Bit of a silly thread though, but interesting to see peoples opinions.

It's all about the "Vibe". Not whether its could go faster, but how it makes you feel.

My old Valiant Pacer didn't drive anywhere near as good as a Z, but you felt like a rockstar when you drove it.

I took the injection off to put triples on, so you know where I stand.

[RBZ 260]

hahahaha love it ....

 

even got rotas and toyotas included. hmmm i thought it was RB vs L anyway.

 

hmm yeah u can spend truck loads of cash on an L to get it going.

 

than it will use fuel as much as W16 veyron and be pig to drive.

 

few mods to rb "bolt on" pumps out few kws still in my case returns 10L per 100km wipe WRX,200sx skylines and mighty V8 of the line. Perfect idle no constant tunning like with carbs or worrying about carbs flooding spitting the fuel on exhaust (cause its perfectly situated) and catching fire.

 

Ben love ur cars both current beast and the 1Jz. but not into crossbreading. still like to see a nissan script on the rocker cover.

 

1jz 2jz are at home in old celicas supras crowns and cresidas. but lets face it they not that good looking.

 

bang for ur buck, relaibility and still can be used as a daily RB conversions are damn good.

 

now anyone selling cheap RB26DETT ? 

[herrods]

hahhaa

 

well I have a foot in both camps here, with an RB conversion on the way, and a L28 (2.9L) on the floor in the corner.

 

I loved the way my car used to drive.  It had epic torque, could keep up with the S15/WRX/skyline etc etc

BUT

I love turbo.  and to go turbo, although you can go the L28ET route, there is a fair bit of involvement in getting that across the line.

RB on the other hand, bolt in and away we go!

 

overall, I would still have to say nissan motor FTW.  Cross Breeding... pass

[RBZ 260]

hahha Dave. well i dont have any more RB so i should be quiet. got a very sad looking l24 in a s1 240z.

 

BTW check ur email. ive sent you a video of my RB now soon to be yours after the comp check. i refited everything back and turned it on to hear the thing running for last time. to me that sounds better than L.

 

enjoy.

 

[620Z]

Well unless I am missing something I don't see any Zeds with RB motors going down the track here in Vic. If they are so fast and reliable maybe someone with an RB motor in their Zed might finally get it on the road let alone reliable enough to race on the track and possible back up there stories. Plenty of "L" series Zeds flying around the track and getting fast times. 

Then maybe we should talk resale value comparing the two. Hmmm

For me well I still think both are missing a few cylinders. 

[luvemfast]

For me well I still think both are missing a few cylinders.

Always thought you were a few cylinders short Craig 

[sco_aus]

V9?

lol, even a near stock, heavy as Supra was keeping up with said 350 Chev engine Craig

Though yes, RBs can be unreliable when worked hard (hence why I prefer the 1/2Js), but when done right, will pump out more torque than a worked V8 (of course thats on boost, but if you can drive, its not hard) and go for a long time. 

[luvemfast]

No more hijacks about V9's and Stupra's

thread is RB vs L series
