Which SR20 should I get for my 95' 240??

[95s-14]

I'm tring to get some opinions on what kind of motor to swap into my 95' 240sx, so far I'm leaning towards a s-14 SR20 but I'm not dead set on it so I'd like to hear what other people have to say. I am kind of limited on money but i'm curious to see what people will say the only motors i've really considered are the s-13 red top and black top. Please let me know what you think. Thanks, Jaime

I would say search and decide what your goal is. What price range are you looking for?

IBTL?

[heartagram]

oh yeah, + 1

[Shift_Kouki]

S14 SR for an S14?

[Shabbernigdo]

get a black top. newer / bit more power o yeah did i mention newer.

[95s-14]

I'm trying to put one together with at least 350hp and that i can use for drifting and also take it to the drag strip for test and tune nights. I'm not sure really how much i'll be able to spend it just depends on if I find a motor that is really worth it i might be a ble to get more money for it.

s-14 blacktop or s-13 blacktop?? I see everyone put the s-13 motors into the s-14's thats why i ask

[mitdrx]

Most people do the s13 motors because they figure that they dont want to spend the extra cash on the t28 when they are just going to change it out anyway. So they buy a cheaper motor set and put the extra into the new turbo.

In my opinion the red top sr is the way to go. The parts availability is much greater than the black top (s14) motor. Also the biggest factor is the wiring required to do the swap is far less involved, you will hear this from many people. Which is the main reason people choose the red top. Also the blacktop has a slightly different head design(low port) while the redtop has a high port design which i have been told is a more efficient flowing head and more capable of higher hp. Just my two cents (proud red top owner/ DD)

[TKOcrewSR]

i would go with an s13 blacktop yea ppl say that your sacrificing the t28. i myself wanted the s14 motor back in the day but i went with the s13 black top, s13 is the better way to go b/c when you start making more power your gonna have to get rid or vvt if you go with cames its less of a headache and like the other guys said parts are more available. but also think of it this way if you want 350-400 hp you will prolly have to with the 2871 or th 28rs anyway so y buy a motorset that is more when you might just upgrade to a much better gt turbo.

[TKOcrewSR]

forgot to mention that if you decide to go with s13 motor think about this redtops are very nice but i have seen plenty of cleaner s13 black tops.

s14 sr...I don't agree putting an engine from an older car in a newer car... might as well go with rb20 or ca18

[TKOcrewSR]

s13 black top engines went up to 98 so yes redtops are older but s13 blacktops are around the same year if not newer

touchè sir!

[TKOcrewSR]

adrian what car and engine do you have. and why dont you agree witth it just wondering what your reasoning is.

purely aesthetics...I'm running a 93 redtop SR on my 92 s13

[adrianfromthecastle]

in all honesty, the differences between the s13 blacktop and redtop isn't signficant enough to say "the motor is newer" because all of which it depends on the previous owner... I've seen blacktop SR's with almost the same mileage as my redtop...

[TKOcrewSR]

yeah you are right you can get black tops with the same or even more mileage but if he wants to go cheaper its better to go with the s13 motor which ever model but i wasnt just saying to go with the blacktop i suggest going with an s13 engine as if he were already planning on upgrading cams and turbo it would be worth it to save the initial couple dollars in the beginning if hes upgrading. plus my full bolt on t28 swap was 300 buck from importintelligence.com . i only work a block away from the shop though and he did my swap.

not to mention read this 95s14 zerothread?id=59346

[highmilehatch]

when you start making more power your gonna have to get rid or vvt if you go with cames

No you don't. There are plenty of aftermarket camshafts that retain VTC.

Go with an S14 SR, make 300whp on the stock turbo with all the supporting mods. When that gets old, upgrade the turbo. The S14 SR is a much more refined engine, and the VTC makes lowend torque/everyday driveability much nicer.

[Cali_Legal_SR!]

highmile is right man. i had a 1990 hatch with a 97 type x blacktop that ran perfect...i recently sold it and baught a bone stock 95 se...swapped in the s14 sr and was blown away by the difference, everyday driving is excellent and the stock torque is almost equal to the torque in my s13 that had a built bottom end...go with the s14...plus, if you intend on keeping a/c like myself, the s14 eliminates finding custom brackets and having to do the welding...after having both types, i would go with the s14, but in the end it does all depend on your budget and what your looking for.

[95s-14]

So far the s-14 sounds like my best bet but I was lookin and what's the difference between the s-14 sr and the s-15 ar besides the 6speed transmission with the s-15? Would an s-15 be any harder to put into a 95 s-14 shell?

[Cali_Legal_SR!]

once you get around 300 hp s15 trannys start taking a ****, the are weak..s15 is gonna be a fresher motor (maybe) with a bit better turbo...im not sure but i believe the s15 sr make like 238 hp? anyone correct me if im wrong, and im sure some jackazz will b/c they have nothing better to do that go look up the exact hp an s15 makes....and then feel educated afterwards

There really aren't that many differences. The turbos have the exact same specs, except the S15 turbo exhaust wheel is made of inconel and has a cast divider wall in the exhaust housing between the downpipe discharge and wastegate discharge. The reason the S15 engine is rated at more HP is because it uses larger injectors stock. If you want to use an S15 engine/6 speed trans you'll need the driveshaft and rear end to go with the trans. You could use a S13 or S14 SR trans on an S15 engine.
