Stock SR Swap thread. For real this time. All HELP IS ACCEPTED GREATFULLY!!!

[CRyan]

Well - for a few months now I have been talking about WHEN my SR20DET gets in. Well.

ITS IN!!! S14 SR20DET "notchtop" complete swap WITH side mount intercooler AND working A/C and power steering. That is to basically sum you up. The engine was ordered through Japan Motor Import. So, as I do this swap, I will also give an overall review on just how good there engines can be.

Also - As of now the only parts I have ordered for this engine are a new aluminum radiator w/hoses, shroud, and 2 12" slim fans, AND an OEM oil pan.

I have only really done a walk around of the engine, taken some snap shots, etc., and this is what I have found. When you see a number with a asterisk beside it, That means there is a question awaiting on the bottom of the post.

1. For the most part, engine doesn't LOOK like it has any oil leaks. We will find out for sure soon, though.

2. Wastegate is aftermarket - HKS, but it is sealed so I don't want to take the chance of hurting anything trying to find out what color the spring is inside. We will find out what its spring is when I have it in with gauge.

3. There are a few male clips that aren't necessarily broken, but can be salvageable.

4. Throttle cable is cut. (1*)

5. Oil stick broke. Luckily, I was able to fish it out. (2*)

6. Has some iridium plugs in it, NGK Iridium T7340-7 (3*)

7. Intake manifold seems to have a little oil; has me a bit worried there might be a blown seal on the turbo in this case. Maybe it just happened to have just built up. . . .(4*)

8. Many vacuum hoses have been cut, apparently the last owner did have a boost controller with the engine, though.

9. Nismo flywheel and clutch. Guess thats one good thing about it.

10. SMIC seems a bit beat up, but looks like it will still be able to handle 10 psi.

1* - Will KA throttle cable work with SR?2* - Can I use oil stick from SR20DE?3* - Any other recommendations on the spark plugs?4* - Any other reason there might be this slight oil build up in intake mani?

OK, OK. . .On to the pictures. Also, PCM valve? You will see the picture. . . Why do I have it and why is the wires cut for it?



What is this?

Thanks for the help guys!

The KA throttle cable will work, you just have to bend the metal bracket under the gas pedal down to let up some slack so it will reach and extend the full range of motion. Glad to see you back, I was just wondering the other day where you were at with your engine. That last pic has your ignitor chip on that gold bracket. For the spark plugs just get some NGK Iridiums heat range 6 for stock horsepower, that what I got. That intercooler looks to be in good shape, do you have a bunch of bent fins or something? Most are gonna tell you to drop it and go frontmount anyway like they told me to. LOWKEY STATUS FTW!!!!

ignitor chip? So WHY would they have mangled the wires? I am a bit lost of words when I look at that picture because, all they did was just cut the wires off.

Also - there are a few fins bent on the intercooler, but I guess nothing too terribly major, it is a STOCK used side mount. . .

[positron1]

The chip itself looks fine just take that old plug off and look on your harness for the plugs that go to the chip...hopefully that wasn't cut off your harness.

[bigred240sx]

dude you still let that nismo picture stay upside down. you coulda rotated it after you got home. ha just messing.

oh and that oil stick. it broke when i went to pull it out. but it was already cracked and my touch made it fall off.

and ignitor chip is with the ignition control module on your ka. so look for wires going to that. we didnt brake or cut those removing it.

[zach-Ka]

Congrats man! I remember you were talking about it not too long ago. Cant wait to see how it goes.

[CRyan]

Well guys - Seeing as I am out of town, I am trying to get together a "check" list. I see most guys do this, but never state what they NEED and only state the more larger modifications. I need to know what is NEEDED for this STOCK swap.

I have a SR radiator with hoses, 2 12" slim fans, and shroud, an OEM oil pan, and a bosch recirculating valve.

What else should be on my checklist? The motor mounts are in good condition.

All the plugs seem to be in decent condition.

My o2 sensor wire was cut short - anyone know if I can use the KA o2 sensors?

[1990-240sxsr20det]

Def get a fmic. You'll want to run more than ten psi when you get it finished LOLBut it looks like you're on the eight track so farLet us know how their customer service and everything isKeep up the good work

[zach-Ka]

Dont forget a fuel pump sir!And you might want to get the heater core conversion hoses. It was hell rigging something up to work.

[kouki munster]

And you might want to get the heater core conversion hoses. It was hell rigging something up to work.

Why? He is putting a s14 sr in a s14, you can trim one hose and make it fit and use a short piece of 3/4" heater hose for the other.

1* - Will KA throttle cable work with SR?2* - Can I use oil stick from SR20DE?3* - Any other recommendations on the spark plugs?4* - Any other reason there might be this slight oil build up in intake mani?

1. Yes just use some washers to hold it in the sr throttle cable bracket.

2. Don't know, but check with some of the sponsors that sell oem parts thew will have one or be able to get you one.

3. NKG bkr6e, they are copper, cheap and will be more than enough for all the stock turbo can put out.

4. All motors with a pcv system do it. And if it makes you feel beter my sr was the same way and ran great untill the ecu shat itself.

[dc1984]

yea, not sure about the s14 sr20's, but my 98 180sx blacktop had the hose running from the crankcase blowby going into the intake, thatle get a little oil all through ur turbo/piping/intake mani but shouldnt be a problem.

also, make sure and check ur turbo shaftplay. side to side and in/out. good luck

[CRyan]

Alrighty guys - a LITTLE update,seeing as I am out of town not really able to work on the car BUT I am able to get a few "essential" parts.

So I went to get belts and plugs today. I know I got the right size main belt - But had a quick question - is the a/c and power steering belt the same size? And if so, was it ok that I got it 3mm shorter. . .Unfortunately, they did not have the exact size.

Also - Little difficult to find iridium plugs here in South Mississippi apparently. Neither Autozone or Advance had NGK iridium with the 7 heat range

Anyway - My radiator, shroud, fans, and oil pan came in today. The hoses should be here tomorrow. I think I am going to take a stab at install Saturday. Because I can't think of much more I need. . .

So if anyone would like to inform me on any other essentials needed for the swap it would be greatly appreciated (and if anyone lives within the Jackson area, come out and join - get a free sixer on me )

But thats all I got today guys - I am putting oil pan on tomorrow, and will make sure radiator will fit correctly and what not. Also probably check out how I am going to fit the SMIC in the bumper. So if anyone might know about how it goes in the USDM bumper, fill me in!!!

Thanks for readingCRyan

[CRyan]

Oh YEAH. One other question.

I purchased a knock off Dual N1 tip with a 2.5 inlet. Would it make much of a difference if I run a three inch from downpipe back, and just have a 3" to 2.5" cuppler just to the muffler? I WOULD just run it without muffler, but hey - I spent 30 bucks on it, might as well get SOME kind of use out of it. . .

[Didderson]

If you can find iridiums with the same SR (91 sentra SER plug will fit) thread, then you can just gap them to .32 for around a stockish heat range. .40 for a colder heat range.

Plug number really only determines the gap, as long as it fits in the threaded hole and threads in nicely, all is well.

For the oil pan I vote you use the permatex red silicon RTV sealant. It's great stuff and actually hasn't started leaking from my oil pan since i re-sealed it during my swap, even through swapping the motor into a new chassis .

Good luck man, but try to ditch that SMIC soon. Better horsepower with a fmic or other applications.Also, if you have to replace your intake gasket I suggest using a thermal one from circuit sports. Frsport.com has them. Cheap free horsepower yet again.

Another top tip, don't run cooling lines to your TB or the iacv. Just a suggestion. You want the incoming air to be as cold as possible.

As for the exhaust, I'm not sure what you mean totally. You have a 3 inch exhaust until the final bolt on portion around the rear subframe area and you'd then run a 2.5"?You're going to be fine with that setup, but you may lose minorly noticeable ponies. I have my gutted oem catback chamber in right now and I can feel the "drag" having this bottleneck in the 3" system.You might as well use it. Better than stock! It'll seal up just fine.

Also - Little difficult to find iridium plugs here in South Mississippi apparently. Neither Autozone or Advance had NGK iridium with the 7 heat range

Stock plugs are 6 heat range and unless you have a larger turbo there is no point in he 7's. The same is true for running the iridium plugs, save the money($30-$40) and put it toward getting a front, mount as you will get alot more out of it then you will iridium plugs.

[CRyan]

Only reason I am aiming at a SMIC is because I don't care to completely chop up front mount and radiator support. End of discussion with the intercooler - I know I WILL want to run more boost, therefore calling for me to run a FMIC, but not now. . .I just want a running working car.

Anybody wouldn't happen to know why the very LAST black wire on the plug from engine to ECU would be and WHY it would be unplugged, eh?

Got transmission on, cleaned up some stuff, replaced belts, got fluids. . .260 dollars well spent today, If i say so myself. Went ahead and got some NGK plugs and gapped them myself - Don't know why I didn't do that in the first place.

I am looking to run a custom bent exhaust - which will be 3" from the turbo elbow back. i wanted to know if it would be ok on the very END of the piping the shop runs, near rear bumper, that it tapers down to a 2.5" to allow me to run this knockoff dual N1 tip. . . I don't THINK it could hurt anything. . .

[CRyan]

Alrighty - Got the engine in the bay and most of the harness hooked up. But DO have a few questions for my fellow niconauts. . .

Noticed old KA harness had an inlet air temp sensor - does the SR have this?

Anyone happen to know the sizing on the vaccuum hose line?

I noticed that my SR harness doesn't have a plug in for MAF. I think came to conclusion I can use the old one off the KA. But I noticed something with wiring on SR harness - There is a stray/naked wire within the other three wires that run to the plug. But there is also a little foil ran over the wire. . .Can anyone explain to me what that wire is there for?

Anyone give me some definite information on repinning the dash plug to the harness?!?!

What the CRAP is the PCM valve for and where does it need to hook up, etc, etc.

Where does the side mount intercooler mount? I found the hole where the turbo side piping goes through - But don't know exactly how I am going to mount it in bumper. . .

Also - My friend has a set of 440 injectors from a Supra, I was wondering if they were able to fit with the SR. . .

As I said earlier, we got a lot done today - Now all that needs to be done is -

Fuel lines (got a 300ZX fuel filter)Harness wiringPower steering belt (Can't seem to find the correct one to fit)

Radiator (Having trouble figuring out how to wire up my 2 fans.)Engine mounts need to be tightenedTrans mount bolts tightenedExhaustAnd some flex hosing for the side mount inter cooler.

Thats it for now - Hopefully I won't have to go out of town for a couple of days and have a RUNNING CAR by the middle of the week. HOPEFULLY!!

Any other comments or information will help me greatly!!
