View Full Version : Putting 96 Sr into a 95KA, any help please

02-02-2005, 03:34 PM
Hello guys. I'm not new to this forum but today I finally got a user name. I'll be doing a sr swap in a 95 5spd 240 and would like to get some info on what wires need hacking please.

The engine is a 96SR.

I've searched and read that some wires need extending, some need the KA plugs attached to the SR Harness or some may need to be repinned.

What needs to get done on the ECU Side to the combination meter

What needs to get done on the Engine side to the fuse box

And what other Gotchas I gotta watch out for.

I'm actually from the Toyota world and have done a GTE swap in a Cressida/chaser, but the 240 is for a friend and I would like to know what all needs hacking before I breakout the cutter.

I would like to do it once and do it right so any help is greatly appriciated. Thanks.

Ok, Looking at the car and looking at the Harness Things are making sence. Now tell me if my thinking is correct.

If you are running the SR Harness with its Matching SR ECU. No hacking is needed for the F4 plug.

And if that is the case, where do the signals for the combination meter come from? the gauges get their signal from where? Also does the Tach need a resistor to convert signal from distributor to coilpack?

Seems like the only wires that need hacking are the lower engine harness where it goes into the Fusebox.

Also, I want to change the front and rear seals on this engine before we drop it in. Can you tell me what seals should I get from Nissan? or the 91-94 Sentra SER seals will work?

We are shooting for the drop this weekend so I wanna get as much info as I can to help with the prepwork.

Yes I have the Pin changes you guys are talking about. Tell me somthing. Now I'm used to the Toyota wirings.

If I'm using the SR ECU, SR Harness, SR engine, why do I have to re pin it? wouldn't that change the pattern on the ECU side?

In the Toyota engine, You have the ECU plug, and you have an Underdash plugs that goes to the gauges and other things. I see this is not the case for Nissan. there is just 1 big plug for the ECU, and no secondary plug for other components.

This is a S14 SR20DET then with VTC?
You don't have a 96 Blacktop 180 S13 SR do you?

I got the guy who's car that we'll be working on to give me the harness yesterday so I can look at it. Now its starting to make sense. The plug in question is the big white plug with the black plastic cover under it. I thougth the plug that needs hacking is the plug going to the ECU.

As far as the wires going to the fusebox under the hood, I Guess you just cut the KA lower engine harness plugs off, and match the wires and put them on the SR wiring harness. I see 3 plugs there, 2 Gray ones, and 1 with a bigh white wire, I assume this big white wire is 12volt.

Am I going down the right path? I'll take some pictures later today.

cool deal, We just might have Fire .... In the hole I mean http://forums.freshalloy.com/images/graemlins/grin.gif

I was looking at the intercooler setups for this car. Is the Optima battery small enough to get a charge pipe to fit or I need a super slim battery. Worse comes the worse, we might have to ditch the windshielf washer bottle.

Optima batteries are huge. No way fitting a pipe cleanly.

You don't have a 96 Blacktop 180 S13 SR do you?

Yes what kind of sr is it??? s13 blacktop or s14 blacktop? Both were available in '96

I've seen the engine on the pallet, its not a S13 blacktop. Its a S14. Only way I can identify it is the valve cover angels down towards the back. 2 gray lines in the center. Again I saw it at night in a garage area so thats what I'm going by.

So the Optima is not gonna fit. Damn, I gotta run a search for battery now

Today I started the swap on the engine. For the most part it is very easy to pull the KA out and put the SR in. I have both the F4 and M63 plugs printed out and started to do the wiring. It didn't take long to figure out these plugs don't match this setup. I think I need more time at this.

On the lower engine harness, I see the KA has 2 plugs and 1 White wire that clips into the fusebox on the side. On the SR it has 2 Plugs 1 black/Red wire that Screws into the fuse box. Even though the wires match wire for wire, The Plugs doesn't match. its a different style plug. So Repinning is in order here. As for the Black/red I'm thinking I need to Cut that and Solder the White plug into its place so that can be snapped in (CORRECT??)

From few searches, I've been able to find 2 user threads that I would like to post and if someone can confirm if I'm on the right track. Thanks

Remove sr20 lower harness from alt, oil press, starter, and tranny, and use the one from KA24. Cut the plug off ka24 tranny's reverse switch (front MOST sensor on tranny) and cut plug off SR20 tranny's switch and wire ka24 one in place. Plug ka24 lower harness into alt, oil press, starter, and only VSS and reverse switch. done

This is what I did on my 96 S14 swap into a 95 240:
..R.......9.......ECCS RELAY......... R.......32
.OR......34......IGN.SW START.....O/L......30
.B/R......1.....IGN.COIL RELAY.....R/L......40

Here are some pictures from day 1. Engine is Out and SR is in. but needs bolting up.
