swapping s13 head onto s14 block KA24DE - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

death2allpop · 10-26-2009, 08:21 AM

As strange as is may sound I am doing it out of need not want. I broke the lower timing chain guide and when the chain started flopping it bent a valve. Instead of going through the expense of revalving the head, I found a good s13 head cheap. I just need to know if anyone has done it, and if so what parts I will need to finish it and be back on the road. Having my wife drive me around is getting old really quickly. Please help

I'm not sure if it will work or not but good luck, and why didn't you just replace the valves? That is the same thing that happened to my sr but I just replaced the valve my self it's fairly easy

death2allpop · 10-26-2009, 08:45 AM

It isn't due to difficulty, the head has a small crack in it that I didn't see until I got it tore completely down. I hadn't noticed and oil or coolant coming form the area that has the crack, but I don't want to take any risks with putting a damaged head on the car.

chanmansr20 · 10-26-2009, 08:49 AM

gotcha, well I got my sr head already with the bent valves for a good price, so I just got some valves from my buddy and replaced them, and now i'm going to take it to the machine shop for a pressure check hopefully everything passes

but as long as it is an obd1 s14 block I think it will work, but i'm not positive, actually really don't know at all but you would think it would work

death2allpop · 10-26-2009, 08:57 AM

The problem is that the block vin reads as a 98, but the head isn't a 98. Nissan switched from the dual cam chain to a single chain for 98. The head I have on the car and the head I just bought are both dual chain. So all points to a nonfactory head to begin with.
The engine was from a 98 kouki that was wrecked and sold by Lethal Injection Motorsports. The guy who bought the engine swapped it into his 90 hatch, and couldn't get it running. He then sold it to the owner or Virjin Jorj, who put the bolted the intake ground wire where it should be and got it running. He then sold it to me. So I have no idea what the hell is going on with this thing. I just know that I need a running car.

I gotcha, well damn man I just noticed you lived in GA, and if I would of joined zilvia a day earlier, I could of sold you a damn near perfect ka, that I just pulled from my car, but my buddy is picking it up this afternoon to throw in a hatch.

death2allpop · 10-26-2009, 09:06 AM

I am trying to avoid swapping it due to funds anyway. I am so strapped at this point that I am close to selling the car as is.

chanmansr20 · 10-26-2009, 09:10 AM

I understand that feeling, well good luck fixing it, I wish I could help but I've never really done a lot of work with ka heads before

death2allpop · 10-26-2009, 09:12 AM

If I had 3300 i would just have Killswitch performance swap a CA18DET into it anyway. GRRRRRR I am hating this car right now

chanmansr20 · 10-26-2009, 09:15 AM

part that beast out, and get you an sr! if it's an s13 I'm sure theres some parts I could get off you lol

death2allpop · 10-26-2009, 09:17 AM

its mostly stripped as it is, but if I have anything you can get it from me. Let me know what you need.

chanmansr20 · 10-26-2009, 09:19 AM

do you have the center console trim, mine is covered in some ugly purple velvet, i'd like to get an oem black one if you have it?

chanmansr20 · 10-26-2009, 09:21 AM

could also use s13 power steering rack, if yours still has it, mine is done for

You're new so I won't be a dick, but posting assumptions and guesses is not a good way to go about here. If you don't know the answer, don't bother posting. Period. You're only going to cause further confusion later. There's plenty of misguided shit on here already we have to deal with without you adding to it. There is no difference in the S14 block between OBD-I and II either. I don't even know why'd you suggest that.

There is no such thing as a single chain on any RWD KA head. They are all dual roller that drive the cams. The lower chain is single roller. You can also tell if the head you have is a '98 by the deletion of the rearmost cam towers, that is the only changeover on later models. Everything else is the same.
The S13 head bolts directly to the S14 block, you'll just need a matching S13 upper timing cover and valve cover as they are different as well, the S14 covers won't work. We've discussed this before, do some research before posting next time.

chanmansr20 · 10-26-2009, 09:26 AM

I don't know why I suggested that either, that's why I corrected my self and said don't listen to what i'm saying b/c I have never explored the ka's

death2allpop · 10-26-2009, 09:39 AM

but the distributor doesn't seem to fit the upper cover, it will fully engage but it is alot more difficult than in the original cover.

You are using the S13 upper cover? Should slide right in. Is the S13 head you're trying to use original? KA heads have a very low tolerance, if it's been machined it's probably too thin. I've had one do that, the distributor was a tight fit because the head was off enough that the idler gear didn't align correctly to the distributor.

I've got an S14 head I can sell you if that helps since you should have the other S14 covers. It's off a '95 engine with 123k miles. The cams are missing but it's otherwise complete and straight.

death2allpop · 10-26-2009, 10:00 AM

how much would you want for it?

$50. I can meet you somewhere nearby too, I'll just need to pull it from the block. Can be ready in the AM. PM me if you want to take this off the board.
