I believe the answer can be found in where the main focus is for each vehicle when it comes to competition. Look at where the SR is mainly used for track work vs where the RB is mainly used [not all the time, there are exceptions in every rule, but mainly]. Long and short circuit, drift, drags etc.

[BAMR33]

SR's used mainly for track... what about the sr 2 to 1 ratio of drift cars at nearly every drift event.

I prefer RB's because they have the potential to make more power. But sometimes I really wish Nissan got their act together and produced alloy blocks to reduce the weight factor up front.

[JustinP]

SR's are good engines but they sound like shit. Can't beat an I6 for engine note!

[T04GTR]

pfttttt. sr20 FTL. when you seem them stripped down you know why there not as good. (from an engineering point of view) rockers that break,blocks that warp with a stud kit in them,single row chain thats not the greatest,good torque but not to revvy and an abundance of machining errors that cause oil leaks.

but thay work lol.

a built 20 would be my kind of engine,vs a built sr20. there just abit more tricky to get rite.

SR's a ghastly designed cheaply made bag of characterless sounding tat but it is undoubtedly torquey.

I personally wouldn't pick a SR over a CA for a road/track car and I personally prefer the RB25/26 in a S13 to either of them.

Re: the RS13 with a RB handling comments. We get this all the time on the UK SXOC. "The weight distribution is all wrong blah blah". Haven't cornerweighted my own car yet but I have seen cornerweight figures from another RB25 powered RS13 and although overall weight is obviously up weight distribution-wise they have a very similar f/r split to a S14 with a SR20DET.

They actually handle very well but theres definitely a wrong way and a right way to build them and set them up. I've been lucky enough to compare mine to a few others over here and the difference in handling was very noticeable.

When set up properly a RB up front actually adds some much needed feel to the steering and improves front end grip. Mine is noticeably less understeerey in the wet and dry on road and track than its identically suspensioned CA-powered sister car.

IMHO the RB really suits the 13, shame Nissan didn't have the balls to do one themselves.

I'd take the rb20 every time purely for the sound. The noise is very important if its a road going car and I want to enjoy the experience. I still stand by that the rb20 is the best sounding rb ever.

The RB20 is inferior in stock form but $ for $ modding an RB will give you better performance all round. and as many have said RB's stroke allows them to rev and that's what you need with a bigger turbo.

you have to look at what is best for you.

RB is best for me...

[rb26s13]

rb26 all the way

How can you say its inferior in stock form? What do std turbo S13/14s make at the wheels? My point is a motor will only be as good as the gear Nissan gave it at the factory. In which case look at the R31 GTSR. There are RB20 with std turbo and intercoolers making 250rwkws

of all the years ive been in the silvia scene, i only know of 1 broken rocker. whats wrong with the chain drive ?!

not surprisingly there is alot of bias here

[tigr33]

sr is way cheaper to modify compared to rb's

[sinistaGTR]

dollar for dollar what makes more power and has much more reliabilty.......RB

[mokompri]

btw, doesnt the rb20 have HLA's ? afaik only the rb26 runs solid lifters right ? the HLA's are the problem with high revs on an sr20, not the rocker arm system.. im pretty sure f1 engines ran rocker arms at one stage did they not

[tek_01]

my mate broke a rocker in his sr20 powered n14

you dont get the power or relaibility but

[Wheezy]

mmmmmmmmmmmmmmm RB20.....revs and engine note get me there

Not a fan of the SR, engine note sucks the wang and id rather have a tough as guts FJ20.

Good to see someone compared an RB30 to a 2JZ......always good to compare an engine origionally designed as a diesel to an over engineered freak

*Wheezy watches the pot stir

[Beer Baron]

It's simple, SR's have rockers...

cheers

not all of them do hehe ok, all the longitudinal ones do. but happines is just an RNN14 head away.

trent: I don't really know the gun SR shops in melb. but you would want someone who knows there shit installing liners that big. I'm guessing they will need to be frozen too and maybe the block heated in an oil bath and they may go in without too much hassle.

[Beer Baron]

agree that SR sounds a bit like fatz attached your exhaust to his ringpiece after half price curry night at the RSL.

all the RBs sound nice. especially the 20 and 26.

[Wheezy]

LOL @ FATZ fartz....smell like doodie too.....

Every SR20 has rockers, GTiR use solid lifters rather then hydrlic (spelling). I dont see the big drama with rockers unless you want to rev over 9000. They have benifites like you can fit massive cams with no modification to head etc.
