240sx s13,s14?

[chefer88]

hi I wanted to know what are the differences between an s13, and an s14? another thing I wanted to know was what are the differences of a 240SX LE, 240SX SE, 240SX LX and any other if they exist? I live in the US but I have heard that they are different compared to the Japan version? oh and also can u explain the engine names (sr20de, sr24ke or something like that)? thanks

Ok this might be a little lengthy but here it goes:
180SX is a hatch back version of the 240SX w/ flip lights, you will only see it called a 180 outside of the US. It mostly comes with a CA18DET (turbo charged).
S13 is a 2 door only model w/projector lights, it comes with in the US a KA24DE, outside of the US it comes with a SR20DE, CA18DET or a SR20DET.
S14 same as above but with out the CA18DET, they stopped making the CA after the S13's were replaced by the S14.
S15 is the newest and the last model that Nissan has made of the Silvia models. I think that it is only outside of the US not sure. It comes with a SR20DET 6speed tranny.
CA18DET: 1.8 liter DOHC, single turbo, auto or manual tranny.
SR20DE: 2.0 liter DOHC, non turbo, mostly auto, some manual tranny
SR20DET: 2.0 liter DOHC, single turbo, mostly manual, some auto tranny.
KA24DE: 2.4 liter DOHC, non turbo, only built in the US.

There is nothing more to explain except for outside of the US they have a J, Q and K versions of the Silvia S13, 14 and 15. The J model or also known as the Jack is a bone stock, no a/c, power or anything only comes in the non turbo model. The Q or also known as the Queen, is the upgraded version of the J. It comes with power steering, a/c, power locks and comes with the SR20DE. And there is the K or also known as the King, it is an upgraded model of the Q, power everything, fully loaded and comes with the SR20DET.

That is pretty much everything in a nut shell, if there is anything that I missed or if you need more info please let me know

In the US they had
89-90 S13 240sx with KA24E (single overhead cam)
91-94 S13 240sx with KA34DE (dual overhead cams)
95-96 S14 240sx with KA24DE (more rounded headlights)
97-97 S14 240sx with KA24DE Zenki (angled pissed off looking headlights)

The following motors were available overseas (never in US) but can be swapped in:
CA18DE and DET in 89-90 S13 180sx and silvia
SR20DE and DET in 91+ 180sx and silvia
The SR20DET came in a couple of versions:
(1)redtop came in S13= better flowing head. the one to get if you are going all out for 350+hp.
(2)Blacktop came in S14= little better turbo but less head flow. the one to get if you are going to leave it fairly stock.
(3)Blacktop from S15= better turbo than the 14 but has the unreliable 6 speed and a wiring architechure different from the US cars=harder to wire in.
And the KING DADDY OF 240 swaps:
(4)RB20DET from R32 Skyline ( I have this one) just bolts right in like an SR but easier.
(5)RB25DET from R33 GT25T Skyline bolts right in S14. tight in an S13 due to larger tranny.

The 240sx's came in:
base model= roll up windows/manual door locks, no sunroof, hubcaps, no spoiler.

SE=power windows and locks, cruise, spoiler and option for sunroof, alloy wheels, optional HUD guages
LE= same as SE but had leather interior and HUD guages and standard sunroof.

Engine breakdown is as follows
KA/24/DE SR/20/DET
first letters are engine family
numbers equal displacement in liters 24=2.4 liters/20 =2.0 liters
D= dual overhead cams (no D means single cam)
E= electronic fuel injection
T= Turbo (TT =twin turbo like RB26DETT or VG30DETT)

The S13's are generally better built cars. they had better materials used in the interiors and better door hinges (s14's commonly have doors that are hard to shut due to week hinges/ never seen any on S13) the S14's feel a little more cheaply made but they are newer and were more expensive, so they are generaly better taken care of. It's getting hard to find really NICE S13's. You are a lot more likely to find a really nice S14.

Also S14 Se's had 5 lug wheels and very few has factory LSD. Just because it is an SE does not mean it had LSD. LSD was part of the Towing package option for S14 SE. Few ordered it. You will also find some non-SE S14's with power windows, it was an option.

wow. yeah they pretty much covered it. also tho, dont let people push you around and tell you that the KA engines here in the states suck. yes the SR20det engine is factory turbocharged. but the KA24de engines here arent that bad either. you can run less boost and get more power. thats my opinion.

[nismoron]

One of the only two cars to beat my RB20DET powered S13 was a S14 running a stock KA24DE with a Z31 300zx turbo at 8-9lbs of boost. He blows motors every few months at that pressure but damn they are fast. He competeds in the USD1. Name is Dennis something with a black S14 with yellow stripes. He creamed me badly. You can Run 6lbs of boost very safe and 8-9 with some larger injectors. After that you need some forged pistons and at 12lbs some rods are in order. Rebuild the motor with forged pistons, some eagle rods and ARP headbolts and you can have 400ish Hp at 12-14lbs of boost with a MUCH wider torque band than an SR. At 8-9lbs he didn't have much if any more hp than I do. It was his torque that kicked my ass!

[chefer88]

How do you know what type of engine (KA24DE, or SR20DE) by just looking at the engine, I know how to find the 24, or 20 but how do you find the rest ? ah and are there any TTs in the US

[iwanta240sx]

KA


SR black top and red top


CA18


no TTs made in the US but there are a lot of imports

Hey Nismoron nice ride you got!! I thought the 95-96 240SX headlight design was called Zenki and 97-98 headlight design was Kouki.

[nismoron]

You are right about the headlights. I was trying to keep track of everything I was going to say, and messed up. Thanks.

You will know what engine it has because ALL US and Canadian 240's have a KA24E or DE. If the motor has been swapped for an CA or SR the it WILL be advertised as such and cost a LOT more. Trust me if it has a motor swap they will be very proud of it.

As for the pictures... The first one (of the KA24) is from an Altima? The engine is turned sideways in front wheel drive cars, but looks the same, just imagine the engine front/back instead of side/side.

[chefer88]

sorry guys but I have another Question. I wanted a 300zx but my dad told me they break a lot and are really expensive and he said I could afford to have one. so im like ok ill decide for something lower like a 240sx, do 240s break often n are they expensive to fix?

[okitex]

In my opinion no, they are very easy to work on due to the space, plus I know out here they are a dime a dozen, I'm not sure about stateside. I have been working on them for 3 years now and they are the easiest thing that I have worked on. If you want the manuals for the full breakdown all the way to the chassi let me know. As far as do they break as easily as a 300Z no they are a little better built than a Z.

[nismoron]

The 300z is very reliable if it was taken care of(rarely) The parts are so expensive that most people that bought thenm could not afford to maintain them and therefor many are pieces of junk. They are very expensive to maintain, especially if you are not doing it yourself. Judging by the questions you are asking, I would not recomend a 300Z. No offense. They are just very hard to work on even for an experienced tech. My best friend has one with about 550hp, but he is the Master Tech at the local Nissan Dealer.

240's are great cars, but as with any car it is only as good as the care that was taken of it. Usually, buy a cheap one and get crap!

[chefer88]

whats a good site to find parts for the 240
