Rb20det In S13/180sx Who Owns One? Thinking Of Buying One. - How quick are they?  

the_random_hero

Compared to SR20/RB25 engined S13, slow.

09ONE

Hahaha is that the only criteria that a car needs to satisify for you to buy it?

If your brother has a stock 304 with a filter, extractors, exhaust and a hydraulic cam (mild) behind a turbo 350/400 in a VH then you will be quicker if you have the essentials.

But Rb20's sound so much nicer then Sr's I would never own a 4banger no mater how much power it may have. I just like the price tag of these cars and want to know what kind of potential they have with basic mods

the_random_hero

This is a completely and utterly stupid way of thinking. If you put an Ecotech into a S13, would you drive it?
SR20 will be more reliable, bigger range of atermarket bits and a much younger engine than the RB20 - not to mention a much more fun car to drive.
If you MUST drive a 6, then find one with a RB25 conversion (I know of one at the moment, probably out of your pricerange though)

toyota_celsior

hahaha yea completely stupid isnt it? And when since did ecotecs sound like rb20's are you telling me that all 6cylinders sound the same? Now that is completely and utterly stupid. I dont give a shit about sr20's the sound they make is a complete turn off for me personally, there is nothing beautiful or sweet about it except buzz I know people out there love it but not me. Im not after the quickest and easyest route. Personally I dont even like nissan and im not trying to start a debate here, personally I rather something with a turbo 1uzfe or a 2jzgte. But im loving the price of rb20 s13's and am wanting to know how quick they can be with basic mods, can they be set up easy for hard launches or will they just have the tendency to either bog down or spin? Show me the rb25 one you are talking about, I dont have a price range, Im willing to pay upto 20grand for something that catches my eye.

a sweet sounding RB is great comfort when you plough understeer your new lead tipped arrow straight off the road the first time you give it so stick through the twisties.

If you want a straight line warrior, the pick something other than a S platform, Multi-link suspension geometry is only good for skids in a straight line, not launching.

why would you ruin a perfectly good autech convertable? 25 will end up twisting a S chassis with no roof like a pretzel

iamhappy46

Those Silvia chassis rails will end up looking like an 'S'

toyota_celsior

What would you recomend for under 10grand that is 2door manual? I was thinking R33. Ideally Id like a dirty big carby v8 with short gears and a stally but im craving turbo 6's and manual as of late.

So basicly the conclusion is they handle like crap with the iron rb up front? So a r32 with the same engine but with more balance front/rear will handle better.



oh and convertibles?? https://www.boostcruising.com/forums/index....=386875&hl=
Maybe if it was the 80's and I had my long hair again and a iron madien cd hahaha.

iamhappy46

1JZ into a S13 is what your really want if your after a boosted 6 in a light chassis.

DJTrisma

I have an S13 Silvia SR20


dont have 0-100 or 1/4 mile times, but its pretty quick.

faster than skylines (except GTR's, they destroy SR20's lol)


My mods include:

T28 turbo
HKS pod filter
Blitz URAS boost controller
oil cooler kit
intercooler
+more

1jz s13? for under 10k on the road? Have you ever seen any for less then 10k? I doubt it, and if it is, its auto.

mongrel_cae71

you could build on yourself for under 10k easy if you're handy, east coast customs sell full kits for $1700(mounts, gearbox mounts, tailshaft, front swaybar etc.) 1JZ manual cut(jza70, frontsump) is under 3 grand(if you shop around),there are a few silvias on here for $2k.

the make or break part is if you could do your own wiring, if so, $3K should be enough to finish one off.

toyota_celsior

Wiring is all to easy for me. And same goes for doing the conversion, but whats the go with getting it all engineered? Do I need bigger brakes or anything like that? Sorry for the newbie questions never really played with imports before.

toyota_celsior

So any one got an answer to my original question aswell?

09ONE

No I didn't answer your original question a dozen posts ago...

toyota_celsior

Oh yea im confident it will beat his 5litre but still wanting to know some rough times,

I still thinking im going to be disapointed with a rb20.

I just wanna know how quick a s13 is with around 200rwkw's.

Im kinda thinking that im just going to get something manual and 1jz. jza70's are pretty cheap these days.

mongrel_cae71

there's a couple of manual jza70's in the for sale section, there's even a aus delieivered ma70 that's been swapped to 1jz/r154 for 5-6 grand

toyota_celsior

Any one else wanna lend some knowledge

20VGT

RB20 s13's are cheap for a reason....they are slow, handle like crap and feel like you are driving a non turbo starlet.

Torque is your friend, having come from the land of V8's, you will be utterly disappointed with an RB20 in anything.

Manic 180

The reason people do the conversion is its cheaper than another sr20.

this is my time slip from my sr20 running about 200rwkw

RalliSki

get a 4G93

iamhappy46

S13 + 350Z VQ35DE and 6 speed = Low 13's in America from stock swaps. Conversion is surprisingly simple as well.

vqswap.com has plenty of ideas as well

Swap can be done locally as well with a bit of ingenuity

i can think of at least a dozen non-gtr skylines that would dust u with your set up. and yes with an rb20 u will get a low 13 sec quarter with minimal mods. they aren't as nose heavy as ppl think with the rb. i think a 4cyl is quite light in the front steering wise.. u will notice this especially coming from dinosaur v8s

toyota_celsior

Thanks for all the comments guys, almost a 13flat from 200rwkw's in a sr20. So a rb20 with similar power would make similar times? Pretty impressive.

I think people are over exaggerating on how rb s13's handle. Ive driven one and it was great not as bad as people make it out to be.

45ult, I drive a toyota celsior 1uz v8 its old but wouldn't call it a dinosaur. Shes currently under going a single turbo project. wont be a rocket but will go alright

I know coming from driving nothing but v8's for years and then going to something with a 2litre 6 will be a downgrade as far as down low torque is concerned, but I don't mind revving the shit out it, it wont be a daily driver just a i don't care about kinda car. just want something that will beat my brothers vh (if its a pig s13, it would break his heart), and I think this will do it

45ult

oh k my bad i assumed when u were talking about v8s' and ur bro's car that u had one too. yeah low 13's from a rb20 is easy i got it with minor mods in my 32.. also choppd many cars similar to your bro's

heggsy

well im pretty sure that a stock boosted sr20 makes more torque than a rb20
not sure but i think it does. so if u are convinced u want an rb20 than think again. go a 25 or even a 3L v6 out of a 300zx. or if u can find a 2L 300zx engine u can get them boosted. my mate used to have one in his ute.. it went hard

iamhappy46

The VG20DE+T is not a good engine, it is also more gutless than an RB20DET.

The SR20DET will make more torque than an RB20 as well.

toyota_celsior

Any more s13 rb20 owners with some times?

Will an s13/180 with a rb20 out handle a r32 with a rb20 with simular suspension?

ZAS

TTR racing $6500 drive in drive out RB20DET... have spoken to ppl with RB silvia's used for drift, they love it, i think if u go RB u have to go 25 to make it worth while but there is more work involved fitting the gear box and stuff so mate its really up to u.. anyway u go SR,RB,1uz,1/2J,VG etc done right all will make your heart go.

iamhappy46

R32 will always handle better than an S13, the double wishbone suspension > S13 Macpherson strut

pipster11

this is true
had an s13 now have a 32
goes good but needs more torque
miss the torque of the sr in s13
but the 32 is just a bit nicer to drive
best combo would be 32 with an rb25 =

iamhappy46

R32 with RB26/30DETT = uber sexy

pipster11

well yeah
i'd love to have some crazy beast like you do but i am a loley uni student
