why s13 black or red or s14 black??

[my95]

Hey guys! I have been a member of 240sx.org for sometime now but have limited my envolvement to just looking at your classifieds and reading bits and pieces of the sr20det swaps and specs in hopes of the day I was ready to do my swap. Well the time has come for me to ask a question about the PERSONAL differences of all the sr20det motors. I see alot of post about the specs on the motors and there outputs but what I am looking for is maybe one or two good reasons that would persuay me to either buy the s13 red or black or the s14 black. I know the s14 cost a considerable amount more for about 20 more horsepower and that the s13 red and black don't have a whole lot a differences on paper. I guess my question would be, Why should I choose one motor over the other and which of the three would be a better (less expensive) swap into my 95 240sx?

Sorry if this has been asked before or if this is a repetetive question.

Cheapest to swap into an S14 = S13. Though if you get an S14 Phase2 has supposedly figured out how to wire the AC.

Of course what really needs to be addressed is: "What will you be using the car for???"

If its drag I would say S13 and dump a bunch into building and tuning. Something like drifting then it wouldnt matter as much because its more on suspension and driver skill. Wangan-not a chance, the S13 and S14 transmission gears are real short and you'll be lucky to reach 140Mph. Etc...etc...

Difference between the S13 redtop and blacktop is nothing performance-wise, purely looks as far as I can tell. The S14 is nice, if you have the money and I were you I would pick one up. But thats purely a judgement call on how much you have to spend.

SR Power costs money, 300hp on an S13 SR is just about as expensive as 300hp on an S14 SR is just about as expensive as 300hp on an S15 SR they are all means to the same end.

s13 has no variable valve timing, one less thing to worry about, and the redtop has side feed injectors i think, and the redtop has a high port head. but with the s14 u get a ball bearing turbo...

very true, if u have the money, go with the s14 black top, 2o more ponies, and lower mileage, if u plan on totally rebuilding anyawy, redtop, if u want the s13 blacktop cause you dont like red valve covers, then go for it

I have heard from the guys here in Japan to go for a S14 motor, they said much more potential for tunning, don't know thats just what they said, I am sure they know a little more then we do in the states about the motors

[my95]

Thanks for the input guys, However have any of you done the swap with an sr motor and if so, what do you wish you would have done different or done instead?

[nlzmo400r]

well i havent done an sr swap, but i bet all of them say, either got the sr sooner, or gone with an rb25det

[my95]

Also, as far as parts availablilities and hp possibilities would you go with the s14 or 13. I notice (on ebay for example) there are WAY more parts for the s13 than the s14. Is this because the s14 is still somewhat new or because in general, the s13 can draw more horsepower making it a more desired motor???

[SpeedRacer1]

Many of the S13 parts off the S13 fit on the S14. The aftermarket is about the same for both, but thats in Japan. Over here the market is equal, there is just less of everything.

Swift Drift and I (maybe a few others from other boards) will be doing a huge 180SX>240SX swap in the coming weeks. So try to find us if you want to have some firsthand experience.

I was asking myself the same question. A question you should ask yourself is, "are you gonna build up the motor?" or "are you gonna leave it stock for awhile?" One of my concerns also, was emissions. You may or may not need to worry about it, but, nevertheless, it was a concern of mine. I read somewhere that the change from the high-port design (s13) to a low-port design (s14) was made for emissions purposes. So the s14 motor would be a cleaner motor...how much cleaner, i don't know.

I ended up getting an s14 motor for a couple of reasons. 1, I like the idea of keeping the s14 motor in the s14 chassis; 2. Since it is a little bit more emissions friendly, I didn't want to chance not passing emissions; and 3. I probably won't do any crazy upgrades to the engine (at least that's the plan :o ), so the stock t28 vs t25 (s13) was more appealing to me.

I though it was only the S15 T28 that was ball bearing, s14 T28 was just regular bearing?

There are conflicting reports, not having inspected either, I have no clue. Places like heavy throttle say they were both balll bearing, while some aussie and/or NZ sites say that only the S15 came with the BB.

[quiksilvia]

sportcompactcarweb.com said that the s14 is a bb turbo

[cpt276]

i believe both s14 & s15 are t28, both bb. the s15 t28 though has different internals. Here's something I found searching:

1994-1998 S14 Silvia 217 hp @ 6000 rpm Garrett T28, ball bearing 0.64A/R Low-port head, VTC variable intake, 203 lb-ft @ 4800 rpm Exhaust, 0.60A/R T04B Compressor cam timing 370cc/min injectors that peaks at cylinder No. 3

Black valve cover with a hump

--------------------------------------------------------------------------------

1999-2001 S15 Silvia 247 hp @ 6400 rpmGarrett T28 ball bearing, 0.64A/R Low-port head, VTC variable intake 202 lb-ft @ 4800 rpm Exhaust, 0.60A/R T04B Compressor cam timing, 444cc/min injectors, better materials in turbo and better wastegate flow design that peaks at cylinder No. 3

European and UK t28's are not bb.

well i havent done an sr swap, but i bet all of them say, either got the sr sooner, or gone with an rb25det

All of them would say "go with an RB?"

yeah.... NO!

[stunt_driver]

get the s14 sr if its going in a s14, because its easier to hook up the a/c, and on s13 sr to s14 chassis its harder to hard wire the a/c, because you have to run a extra wire for it and hope that helps, also alot of people from companies like phase2motortrend can do remote wiring services for s14 sr to s14 with working a/c

[nlzmo400r]

All of them would say "go with an RB?"

yeah.... NO!

well i know you're a die hard SR fan, and i didnt mean any offenes with anything i said, i just figure most of you guys would want even more power, and i see SRs are becoming more and more common, does that bother u at all, since you've had yours for a while now? and a lot of these ricers are trying to get their hands on SRs and such, which drives the price up??

Oooohhhh the SR is becoming popular, because its only been out 13 years now. Big deal. KA's are what scare me.
