Nissan Engine SR20， RB20

[kuenny]

i'm a newbie in automotive...
wanna ask sifu that...about sr20 and rb20....
na or turbo one better?
how about the maintanace... and the spare parts?
maintanace n parts cos lots of $$$?
how about ca18det?

if a old skool... BMW... for example... 520i... year 85...
wan drop nissan engine... izzit able?
agak need how much $$$ le?

izzit got diff between... sr20 s13 lar... blur top... red top lar.. pulsar lar...
izzit got diff one aR?

sorry for these stupid question....

Hi Kuenny....If really newbie, you won't know which is SR20 which is RB20 already. I bet you have been reading alot.

Anyway, maybe you should start with what you want to do with the info?
You want to build yourself a drift machine? drag machine? hhh just kidding. But need to know so you can lock down your scope of work in searching for the motor!

Rebuild a 520i with a RB20? I saw one with a toyota Sourer motor! (see pict)
Can consider Toyota's motor too. More for you to read.

SR20, light, powerful. Potentially boosting to 250BHP if properlly done.
A31 for drifting love this motor. Powerful and yet not heavy.
I had one SR20DE on a SSS Bluebird. FC on the highside...but lots of fun.
SR20DET, saw it in action, don't play play....
Parts are surely cheaper then RB20.

RB20, Bigger but more torgue. Not many chassis can fit this baby!
Not much info from me on this motor.

Try to google SR20 and i remember i once had this link that tell which SR20 has VVT and so on...

Whatever that case, buying a halfcut would be at least 3k and above..don't think about old engines la. not worth your time and effort.

ic... thank for ur reply...
RB20 i heard it from my friend... his daddy old merc change engine... drop in a rb20det.... cost 9k...done it 5 years ago... but without those boost meter... the car quite powerfull...
y don;t think about these old engine le?
so should use wat engine?
izzit these engine is more expensive that the other one?
so... should use wat engine?
i mean.... maybe with turbo?

Check out this page for more Nissan Engine's details.

Don't go for those 10 years old engines...something after 1996 should be interesting.

brother...1jz in a bimmer is common already...i had 2 friends who throw in a 1jz into their bimmer 7 series...with full bodykit and dark tinted glasses...they are a chick magnet...hehe...but i prefer sr20...i like the power from it though...

okey...
thank you!

 

[topui11]

haih... ok.. let me guide u to Jalan yang benar. hehehe

SR20det got 4 variant
S13/180sx red top, 220ps
180sx late model, Black top, 220ps but more torque
S14/S15 blacktop VTC, 240ps
S15 Spec R blacktop VTC, 260ps.

RB20det also go some variant
R30/R31 RB20det red top 200ps
R32/A31 RB20det silvertop 220ps

SR got more torque than RB.

RB is smoother in power delivery than SR.

Stock Standard RB20det can take up to 300ps, 1.2bar with properly setup turbo/wastegate/injectors/MAF/Ecu/.

Stock Standard SR20DET can also take up to that much but a lot more needed than RB20det.

best solution? if u got the money, go for S14 SR20det. it's cheaper than S15 SR20det. spend some $$ and get the lash-killer kit (available in Singapore). Boost it up to 1 bar, tune with SAFC and give it a properly setup exhaust/manifold, you'd be hitting 280ps or more.

budget? go for RB20det from R32 GTS-T type M. the best thing is that it comes with 4pot brakes! change the turbo to RB25 turbine, plug in SAFC and boost controller, change to front mount intercooler... boost up 1bar... u'd be hitting 260ps+ but really pushing it already.

 

[dream.tent]

Tapui ah....I think RB's torque is far more the SR la....
Anyway, your info is very chun..thanks.

[kuenny]

RB is 6 piston engine le... and SR is just 4 piston...
y SR got more torque then RB le?
tak faham...
and... which engine cost more le?
another stupid question...
y same is SR20DET... but got few diff type one le? and not same year n diff hp one?
how about FC?makan lot minyak?

 

[dream.tent]

I think Just a Typo error la..no worries.

Ah! SR20DET is just the engine ma...they can do so much more..

Change the compression ratio 9.1:1, 9.5:1 that will give so much diff...
Then The CAM, put VTC bla bla bla...change the ECU programming and you have a whole new characteristic for the same engine.

Even with the same engine, tunning the ECU alone can give you a few % increase in BHP.

If the VTC is working well, shouldn't worried about the FC. But again, if you want your car to perform, have to let it eat a bit.

Get a SR20DET, set it up and Dyno it...Then if you want to see more flexibility, put in a piggy back ECU to fine tune it. Give yourself a few choices...lean fuel mode for city driving....then rich mode for action.

 

[topui11]

bro dream.tent

i owned SR20det (S14 200sx) before and RB20det (R32 and A31) before... :) trust me, SR got more torque.

both engines gone thru some evolution til the end of their life cycle. same like 4G63 in mitsubishi.

VTC is quite mild, don't expect something like VTEC power here.

Fuel Consumption is quite ok, provided u keep it as near as stock as possible.

 

[Raja_Mongkut]

i think got more variation rite...

sr20det oso comes with u12... red top or black top.. 2 wheel or 4 wheel

 

[kuenny]

oh....
by the way.... i'm not understand about the compression ratio... i find some info be4 already.... but still tak faham...
and wat is VTC?
Then if you want to see more flexibility, put in a piggy back ECU to fine tune it.>>>> can u explain futher more about this?
that mean i can chose for wat mode while i driving?

raja mongkut, i believe we're talking about RWD SR20det here, so no need to confused the guy even more. :D hehehe

kuenny, you don't really need to up the compression ratio. what u need to understand is what the engine is all about. upping the compression is scary since it's a turbocharged engine. usually, people would DECREASE the compression ratio in order for the engine to take more BOOST.

VTC = Variable Timing Cams, kinda like VTEC in honda and MIVEC in Mitsubishi.

installing a piggy back ECU is a big step, even for any cars. this is because you might end up worse than before. if you don't know what you're dealing with, better stay stock standard.

btw, in a BMW (other that E30), i suggest you go for RB25DET instead.

P/s: dream.tent.. no offense bro, but seems like u don't know what you're talking about. if you have experience with both engines, you'll know what to say or what not to say in here.

 

[dream.tent]

Bro, I think i can see what you mean...
The RB is not as active as SR...looking at the stats...can see that RB is weak. Maybe it has potential to be modded to be very powerful...but stock, it's performance will be lower than SR! thanks!

RB20-DET
Type: 1998cc EFI DOHC 24 valve 6cyl turbo
Power: 215hp @ 6400rpm (auto 205hp @ 6400rpm)
Torque: 196 ft/tg @ 3200rpm (auto 198 ft/tq @ 3200rpm)

SR20-DET
1997cc EFI DOHC 16 valve 4cyl turbo
Power: 155hp @ 6000RPM
Torque: 162 lbs/ft/tq @ 4400RPM

qouting figures from websites can be deceiving.

personally, i've tested R32 GTS-t Manual against S14 200SX Auto.

Drag = S14 win outright after 200meters
Drift = S14 better if manual... R32 kinda hard but very stable chassis.
Wangan = R32 (120kmh to 200kmh is a breeze... can't even feel u doing that fast!)
Touge = R32 but i like the S14 power up the hill, but in terms of fun factor, S14 wins.
top speed = R32 max out at 245km/h, S14 max out at 265km/h. This is mostly due to the fact that the S14 auto is running lower final drive, hence more top speed.

SR20DE S13 is rated at 155hp and 19kg/mm of torque
SR20DE S14/15 is rated at 170hp and 22kg/mm of torque

SR20DET is rated at 220ps (about 210hp) and 28kg/mm of torque
SR20DET VTC S14 is 240ps (about 220+hp) and 29kg/mm of torque
