another nuby SR question

[93 Chuki FB]

hey guys, i recently ran into some money and i wanted to do a S14 SR20DET swap for my senior project. I originally was gonna go KA-T but after some thought i realized that a SR would handle boost much better (as it was designed with boost in mind unlike the KA). im gonna be doing all the work my self, my 1989 coupe has a DOHC KA swap already done (by me) and everything works, except for the tach and A/C so everything has been converted to DOHC. So my first question is, what is the cost of a bare minimum S14 SR swap? and is the wiring any different from a redtop? can somebody direct me to a website or something that has a very easy to follow wiring diagram? So im buying the SR from JDM-online.com for about $2k, i wanted to change the oil, water pump and thermostat , and spark plugs. That would be it for maintenance, as for as mods go im gonna do a FMIC and boost and water temp gauge. So yeah if anybody could offer some advice that would be great.

Everything you should need is in the FAQ. As far as the wiring, I recommend you speak with OM3GA about one of their made from scratch harnesses. Quick question though.. Why an S14 SR and not an S13 SR?


Aren't you the guy that had the thread WDRacing and myself turned into a KA vs SR battle?

Welcome to the dark side.

lol thats me alright!!! yeah ive been collecting parts for the KA-T and school has taking up most of my time lately. But yeah i completely forgot im turning 18 in August so i talked to my mom and she is gonna give me $1500 for my B-day. and a couple hundred here and their from relatives so that adds up to a SR swap (i hope). I haven't completely abandoned my KA-t project (not yet anyway lol). Im just trying to add up the cost of both projects and figure out which one is gonna be best for me. the site sells both engines redtop and S14 sr's for the same amount so i figured the S14 SR it be the best choice. But yeah if anybody has a site that uses pics for the wiring that would be great!

[PyR0NiAk]

Try out an S13 Blacktop SR. They're newer but you do everything just like a redtop, and they only cost about $100 more than the redtop, usually.

it actually costs more then a S14 SR, so is the S14 SR that big of a difference when it comes to swapping it into a 240sx?

Here is a link to the website im talking about:
S14 SR

S13 blacktop:

S13 redtop:

Check out the compression numbers on that s13 blacktop compared to the s14 notchtop.

Meh. . . 2000 dollars won't get you buy on an S14 SR swap. I spent 2275 and ended up having about 3000 in a STOCK swap after I was done with it. . .

The wiring harness can go to Wiring Specialties, because then you will always know it will be done right.

And is it just me, or are more and more people having fitment problems with the S14 SR into the S13 chassis? I was reading on a local forum about it, then I noticed something on this forum about it. . .and so forth.

[CRyan]

AND COMPRESSION ISN"T EVERYTHING PYRO!


Gah.

thats pretty much the goal, all i really want is a stock S14 SR. The only mod im doing is the 255lph pump and a eBay FMIC, and thats it (besides for tune up parts). So u spent about 3k for the whole swap? does that include sending the wiring to a specailist? im hoping to spend around $2500 total, is that reasonable? The motor cost $1960 after shipping and tax, then the pump is another $125, then the FMIC is about $150, and tune up parts are about another $50-75, sending the wiring to a speacialist is about another $300. Does this sound right? is there anything i missed? Ohh plus a boost gauge and water temp gauge so another $50-125. i came up with a total of $2732, and the swap doesnt have to be finished right away, can kinda take my time to gather money and supplies.

[CRyan]

Where are you getting that price on a S14 SR?!? I used stock SMIC, stock fuel pump. Only modifications I have to it are the HKS wastegate, megan downpipe (got for 75 bucks) full 3" exhaust ($200), and a few other odds and ends, most of the modications to the engine actually came with the engine.

You just have to realize, fluids, extra wiring or anything, stuff like that will stack up.

ok, i might just use the stock SMIC, so is it safe to use the stock fuel pump in my car? if it makes a difference the car was originally a ka24e then swapped to a ka24de, and hopefully a SR20DET. The price of the SR is from the link above, the price includes shipping and handling the exact total for the SR is $1949, fluids wont be that big of a deal. So back to my main concern, what is gonna be the difference between this swap and a redtop swap? whats the difference? and my plan for the exhaust is to buy a down pipe and then run a homemade straight pipe, and i will be buying a BOV.

[PyR0NiAk]

Most swaps don't come with the SMIC unless you buy a full clip. Besides, you're always going to want more boost, so you might as well buy the front mount while you're under the hood anyway.And no, that does NOT include shipping. When you go to checkout, it gives you an option to estimate shipping costs. When I got my motor from jdm-online it cost me like an extra 300 bucks to have it shipped here.

Gah.

That's right. THREE slaps! Someone might think you're serious.

i just checked again, that price does include shipping. I did the shipping quote thing and it says free shipping included



take a good look =D

[93 Chuki FB]

so can anybody answer my questions? can i use the stock fuel pump and what are the differences between a redtop swap and a S14 blacktop swap?

[PyR0NiAk]

doesn't change the fact it has low compression


There's no way I would use a stock fuel pump..

Lol wut?

thats what i thought, so what are the major differences between the redtop and S14 blacktop swap?

[93 Chuki FB]

yeah 160 across is low comp lol im just messing with u

http://www.youtube.com/watch?v=tvv_Ptpa ... r_embedded

[PyR0NiAk]

considering most have 170+, yes that's low..

Think about it.. Most S14 SRs typically go for 300-400 more than an S13 motors. There's a reason that one is so cheap.

Wow here rwd-sr-faq-version-2-0-t306956.html
other than a few wiring differences nada on the install

...and u can use the STOCK z32 fuel pump

[DuckyD]

I have never seen an SR20DET with compression numbers that high. 175 across the board seems really high.
Usually when we do compression tests we expect to see between 150psi - 160psi.
Just saying, looks a bit suspect to meh.

thats what i thought, so what are the major differences between the redtop and S14 blacktop swap?

S13 redtop - T25 turbo, about 200hp in stock trim, skinny-type o2 sensor
S13 blacktop - T25 turbo, better pistons, better oil pickup, fat-type o2 sensor, typically newer
S14 Blacktop - T28 turbo, better pistons (54c's), better oil pickup in the oil pan, variable cam timing on intake, different intake manifold

I don't care much for the S14's variable timing and seems to cause more problems than what it is worth.
But the slightly bigger T28 turbo is almost worth it.

is that the FSM? if so, that s*** is awesome!!!! holy crap!!! that made my day. isn't it awesome when u use resources that are found on Nico club........ actually this is what made my day

but ur link led me to this ^ so thank u!!

i dunno, 170 seems kinda high for a boosted motor. Dont forget that carbon builds up in combustion chamber and raises compression. So thanks to Nico club my pen15 has grown about 6in and i will attempt the wiring myself

[PyR0NiAk]

Mine were all over 160....

I don't know about the S14 wiring, but the S13 wiring was pretty simple. A little tedious with a s*** soldering iron, but nothing complicated.

yeah i was looking through both, and it looks like the S14 is a little more complicated. I just bought a soldering iron and some heat shrink. Ohh and i almost forgot, i also ordered a Mishimotto radiator. I forgot to ask, but what can i expect from JDM-online? is their anything i should look out for or anything like that? what would u rate ur experience with them? ive made up my mind, SR here i come!!!! ohh and ur not gonna tell me that 160 across is bad on a cold compression test, and they weren't even holding the the throttle open. I just talked to a couple of ppl and they said 160 across is pretty good for being cold and what not.

[PyR0NiAk]

There's were 155... That's why I was saying look out. lol Either way. the only thing wrong with mine, was the CAS got busted during shipping. JDM-Online replaced it for the price of shipping.

so today i got the paper work finalized for my project, so its official now, i either go through with project or fail high school So does anybody else have a review for JDM-online that they would like to share? Is their anything in particular is should be looking for when i start my swap?

[DuckyD]

I still think that 175psi is entirely too high, unless the motor is built.
If you order a motor from them, do your own compression test and let me know what you get.

ok, i really think the number isn't as important as how even the compression is

I can't believe you're thinking about doing a lame SR swap for your senior project. Not only are you dumping cubes, which we've already acknowledged is a loser idea in the "other" thread, but you're forgetting an entire realm of options as well as repeating an overly done swap.

I must ask, if the KA is being pulled out, which isn't a bad idea IMHO, why the hell would you ever install a smaller motor like the SR20? With the budget to make one of these little bastards make any real power you could do a simple GM 350/any transmission swap and have a car seriously fun to drive. No one can argue getting that happy feeling when immediate torque is applied to your whole body every time someone stabs the go peddle even a little I smile like a kid driving his Dads ride on lawn mower for the first time every time. You're not getting that smile with a 2 stroke...I mean SR20

Lets face it, the SR is a torqueless p**** compared to the 350+ft lbs of right now torque available at throttle tip in with a simple carb setup and some cheapy Vortec heads bolted to a good ole 350

Which btw can be delivered to your door for under $1000/short block should you manage to make more power then any 240SX chassis should handle without modification for torque twisting. You'd think that would be enough argument right there, but I'm sure someone will argue that less is more...you don't see pron stars with little d!ck for a reason bro. You might even hear that less is "more efficient"...you try telling her that buddy It's called an UPGRADE for a reason

Sack up and take the road less traveled and you might even be remembered. Don't let these Sallies talk you into being lame. We have guys in the Hybrids forum doing fantastic swaps right now. One is a DIY 383 Stroker with a turbo big enough to feed kittens!. FFS man...don't be like all the other sheeple. Step out of the box
