FC3S vs 240sx
 

Ok, I knew the subject would turn some obvious answers but there's a twist. FC3S with a 20B vs. a 240sx with an SR20DET. What's the general consensus on which of those two cars would win a race?

the fc. over here in aus we have plenty of silvias, 180sx's and 200sx's (basically all 240sx's with the sr20det) and power wise they are comparable to the 13bt... they've certainly got nothing on a 20b.

Charlie

3 rotor will whop there asses!

2 rotors r sick 3 rotors r inssane!!!!!!!

20b would stomp all over just about anything. why would the sr20det be any different :)

I'm not all that familiar with SR20DET's I was just asking around. (that and the fact that my friend thinks he's getting a 240 with an sr20, and i've got my Turbo II, so methinks i'll have to get a 20B to stop his fat mouth from talking big to everyone)

isn't there an sr20dett?

what year is the engine from?

you don't need a 20b.... you might need a 20b if he was chucking an rb26dett or something in, but otherwise no :)

Charlie

Not sure about a twin turbo SR20DET but there is the RB26DETT which is the stock engine for the Skylines.

the 13bt is equivalent to the sr20det
the 13bt gets the edge on horsepower though
the 20b is a serious high horsepower motor that would be up more in the range of the rb26dett but that is nissans superpower motor
the R26b is more of mazdas superpower motor thus the motor that won them la mans
there is no stock sr20dett ehh? i think

stock engine for skyline gtr's drew... big difference :)

My Skyline knowledge is a bit shady, there were Skylines that WEREN'T badged GTR?

not all skylines are GTR's, check Motorex's website.

no but the gts and gtr's are the turbo powered models

very few are gtr's...

Charlie

So I see, forgive me for generalizing.

Just go with a To4 & a good fmic on your TII and you should be fine.

A stock tII vs a 240 with a sr20 in it and a fmic the 240 will win. Ive ridden in both and the 240 pulls harder and handles better. but after 120somethin the 7 would pass it becouse that damn speed limiter.

my bro had his stock sr20det running 218rwhp. I think thats more then the stock 13bt.

and 5th gear pulls so hard on an sr20 compared to a 7..

blah.. get all your bolt-ons (intake + full exhaust), 720cc secondaries, a walbro fuel pump, and a boost controller. Thats all you'll need to whoop on a SR20det 240sx. Turn up that boost and blast away.

Haha this is a funny post. I beat my friends sr 240 all the time and he has a big 28, intake, full greddy exhaust, downpipe and greddy fmic, walbro fuel pump and with avc-r and safc. All I have is racing beat full exhaust, fcd, hks intake. I havent even put on my sbc id boost controller. I think he needs more fuel though because he should be beating me. Anyway, with the right turbo, fuel, ecm and tuning you should be good.

a stock sr20det doesn't do anything like 218rwhp.

Charlie

Yep, the only way a SR will do 218 stock is if its a SR from a S15. Those have a T28 stock.

No, There was never an SR20DETT, and to actually fit the S15 SR into an S13 isn't really worth the trouble. Just a redtop SR with an aftermarket turbo would be a much better choice than an S15 blacktop for the money.

what about a 240 with a rb26dett (im pretty shure thats wrong, a skiline engine) and yes it's been done, Vs a fc with a 20b, seems to me that that might be a better match up...

RB26DETT is right, and yes, i've seen it done. stock to stock I'd give the win to the 20b, but if the boost on the RB is turned up or aftermarket turbos are put on the it, the RB would probably win.

I know damn near everything that can be done to a 240 cause i looked at almost every option when i had my 240, and to be honest, the SR of any type is a waste of money compared to what you could make the KA24DE capable of if you changed parts around and turboed it. The SR is higly over rated and many people go for it just because its a popular trend. don't get me wrong, the SR is a great engine, but the stock engine is capable of much more.

well, the SR is nissans priemum, light, performance engine, it's more efficent than the RB and easer to get ahold of so thats why it's so popular, just like if you ask any toyota(spelling) person then the'll tell you the 4AG is the best thing in the world, and im shure there is plenty of people here willing to clame that a 13b is the best...

What is the difference between the SR red top and the blue top?

when i was first geting into imports *yes i got into them the right way :)* i was intrested in the FC then when that wasent a option for a whale i got into the 240s 180s and silvias i whould say it whould be about an equal match between a SR20det and a 13BT stock we arent talking mods here just a straght 180SX or Silvia verus a FC3S might as well make them both J-Spec whale we are at it.

The SR20DET in the S15 is rated at 250HP, the older ones are around 190-210. This is all stock.

And whoever said the SR20 was better than the RB26DETT in any way, you're wrong. The only downside to the RB is the price and fitment issues in a 240SX. That's why there are very very few of these in the states. (probably less than 5)

As for RB26DETT vs. 20B, the nod has to go to the RB due to its extreme durability. Just like Toyota's supra JZ these are often pushed up way over 600hp and they take it in stride, no problem. From what I've seen the upper stable limit for 20Bs is around 700HP, whereas there are many RBs in the 800-1000 range.

20B vs SR20? that's a joke. the 20B would absolutely and completely smoke the SR20 mod for mod.

I hope you all have the $10,000 just to mod the RB26 to produce numbers like the 20B - the 20B would just be easier to produce big numbers (i.e. close to 1,000 hp).

The Nissan has an edge with the double wishbone suspensions, but it's build quality (S13) is CRAP!

that may be true of the RB, but i don't think you could call a 600hp supra reliable/durable.

beh! all the 240SX's in the states have the ka24de (hence the name 240sx). You dont need to worry about anything, the engine is rated for 150hp, and no one makes anything for the ka24de truck engine/ altima engine. :)

that ka24de sure does last though, i had an older altima with one and had around 200,000 miles before i got hit and the car was totaled. Never had a problem with it and i was drving the piss out of that thing. I took it to fricken gingerman race way the year before and road raced the car. still pulled strong till the end. Even beat my frineds new zx2 escort!

"the R26b is more of mazdas superpower motor thus
the motor that won them la mans "

does that coem in any car? or opition? or is it stricly for the le mans car? n super high power concept shit ? haha

or do people actually get that iengine into their 7's?

20B in whatever rwd car :)

Coolness, looks like I have my answer.. :)

218rwhp

alls that was done was take off the air filter and just run it thru the maf and also remove everything behind the downpipe.

With the full exaust it was only pushin 180somethin hp.

right... at least you've stated your definition of stock now :)

Charlie

A couple more things, There was no SR blue top, There was a red top, in the S13 Silvia K's and early 180sx, the black top is in the S14 and late 180sx, and the S15 has the 250hp black top. There are no differences between the S14 blacktop and the S13 redtop whatsoever, just the color of the cam cover.

OC, not all 240sx came with the KA24DE, the 1989 and the 1990 were SOHC and had the KA24E. Heres a breakdown for you. KA - series, 24 - displacement, D - Dual Overhead Cam, E - Electronic Fuel Injection. All is the same for the SR as well, the T in SR20DET is for turbo, but i'm sure that one was obvious.

another note, The 180sx is named so because it orignally came with the 170hp CA18DET engine, which is also a popular engine swap for the 240 because of its lower price and demand.

Yeah no difference whatsover. :confused:
The black top S14 has a low port head and the S13 red top has a high port head. The S14 blacktop also has VTC (variable intake cam timing) which the redtop does not. There is many other differences...turbo size, hp, etc..

I disagree on that.... The rb26dett like the 2jz-gte are two motors that can achieve the 1k mark the easiest and cheapest that i know of and still remain on stock internals.... (well 900 is the number the bottom end can handle according to craig paisleys drag supra)

the 20b is an amazine machine yes indeed but i still think the RB would beat it on the money category...

Of course this is a whoose balls are bigger thread and these are balls we dont even have so oh well cheerio..
-Gabe

a stock internals rb26dett making 1000hp? bwahahahahah, no...

Charlie

oh yeah I forgot It was a s13 red top.

I read somewhere that the older red tops were the best choice becouse their intake ports were beefier creating more power with the same boltons. ie if you were to put a t3 or whatever on a s13 redtop and a s15 sr the s13 motor would make slightly more power.

Which car doesnt really matter on how fast you can go

What matters is how deep your pockets are :D You can make ANYTHING fast...

agreed, also in many cases it is the car as much as the engine, you could take a semi engine and push a couple thousand, but it doesn't change a damn thing, it is possable to get 1000 hpr out of a rb26dett but weight Vs weight the 20b is lighter(may be wrong, but i think so), im shure a 20b in a Fc pushing 700hpr would take a RB26 in a, o say a s15 pushing 900 or 1000... of coarse these are big numbers that many of us will never see, much less ever own... :cool: :cool: :cool:

Well obviously you dont know about SIGNAL AUTO of japan the owner has a T78 R34 and it makes almost 1000hp on stock bottom end :eek:
