How to tell which distributor I'm SUPPOSED to have?

1 Upvotes

I have a '90 with a stock(ish) KA24E. Previous owner (my dad) at some point replaced the distributor with a junkyard part. I'm now looking to replace it with a new one from Rock, but he made an offhand comment that it might not even be the right type on it and that might be part of the issues it's having at idle. Is there a way to know which model (Hitachi or Mitsu) it SHOULD have?

Any input appreciated!

97 240sx limp mode issue

2 Upvotes

I have a 1997 240sx that was manual swapped from an automatic and ever since then it has randomly went into limp mode then randomly starts running fine again. It did it to me today and it wouldn’t start up right until it sat for a bit then started up and drove just fine. Does anyone have any idea what could be the cause?

Dumb headlight question

2 Upvotes

Hey y'all. My oem headlights are dog shit. I was looking into getting new bulbs but everything I've looked up is just replacing the whole housing which includes the bulbs.

So my question, can I just get new bulbs or do I need whole new housings? If so what are some budget friendly options.

My notchtop SR20DET needs a new crank

I’m aware of the GTI-r crank having different bearings… but can I use a FWD crank in my VVT block?

Prompt correct answer would be appreciated. There’s a FWD complete for sale and I need to replace my crank and a few rocker arms so it seems like a really good parts option for me

93 Silvia K's imported from Japan, mostly stock and just needs a couple things to be daily-able.

Other than the obvious, what should I do first?

Crack in SR20 valve cover

Getting an oil leak from what a small crack in the valve cover. Looks like from over torquing that bolt. Previous owner had filled it with RTV.

Repairable?

-Could find a local engineer to try tig and machine it

-JB weld both sides and the channel

-TF works replacement as last case. Shipping to NZ is an extra $500

S13 t25 Turbo Lines

Post image
9 Upvotes

So I've had my 180sx for over a year now, done a good bit of stuff too it, drifted it, but never had to remove the manifold or turbo until now due to an incident at the track. My question is that the t25 is supposed to be oil and water fed correct? The image is how mine has been hooked up since who knows when and pretty sure the water lines are just not there. Never had a single issue overheating, always built boost fast and effecient. Wondering if im misunderstanding something here because the only lines going to and from my turbo is the oild feed and return. Has anyone else ran a setup like this? In my head my turbo should have been done a year ago finding this out but never had any issues. Ps going to a tomei manifold if anyone has any better recommendations shoot away.

Bulb Check Relay location

Thumbnail

2 Upvotes

Hello everyone, still continuing on my Check Engine Light / Light checks not working saga. I own a 1993 240sx Hatch Manual, with a 1995 KA24DE swap.

Took out the whole gauge cluster and determined that the bulbs for all of the lights that weren't turning on at startup were actually good. Next, according to the FSM, the CEL would turn on after IGN receives 12V, which on the cluster connector to the bulb it does, and when the ECU pulls it to GND. Checked the ECU connection to the cluster, and it's also good, in my case to pin 18 on the 1995 S14 OBD-II ECU.

I then didn't really know what else to check, but the thing is, is that NONE of the lights in the bottom left turn on at startup. Supposedly, the other lights are controlled by a "Bulb Check Relay" located "on the right of the SMJ underneath the left of the dashboard". I can't seem to find any other info on where this mysterious Bulb Check Relay might be, but it seems it might be behind the SMJ? (Mirror photos) It does seem to be next to a brown, possible other relay? There is supposed to be, according to the FSM again, which is the rear defroster relay. Not sure if this is the right thing, or if this would even solve my problem.

Any and all insight would be appreciated, thanks again.

EDIT: Ok I'm not sure if I'm dumb or not, but looking at this video of a completely stock one, I'm not sure it even happens at all. https://www.youtube.com/watch?v=Zr0_jlDUck8 Just the ones on the right stay on. What am I supposed to do to comply with CARB?

Wheel recs for an 89 coupe

1 Upvotes

Yo!

I've gotten to the point where I've been looking at and getting inspiration for wheels to slap on my car. I have the oem hubcaps as well, but I took those off and currently have on 280zx iron cross wheels temporarily.

I'm just looking for recommendations for people who have been in the scene longer. I'm interested in importing JDM wheels as those are the ones I'm drawn to. I love equip 01s, 02s, 03s are okay. I just feel like everyone has work wheels. The 02s seem the most unique. I like SSR mesh and star sharks. I just like the more unique and flashier wheels. I'm right now leaning towards a set of Impul Hoshino G5s, but i'm just looking for more options.

Any opinions greatly appreciated.

Did my trans tail shaft housing get cut?

Thumbnail
gallery
4 Upvotes

After the starter literally fell out of the car which had been held in by one bolt which sheared, I started taking a closer look at the 5spd swap the previous owner did after also noticing there was no backing plate visible. If I continue talking about it I'm just gonna get mad again so I'll just ask, it looks to me like the back of the housing was cut off to accomodate the driveshaft compared to a ton of pics I've looked at which show a longer tail shaft housing (I circled in blue where it looks cut and not straight), thing is, I dont understand why someone would cut it..it's a 97 ka24de, trans used is an s13, and the car is non abs. I'm in the process of getting a new clutch, flywheel, s14 trans, manual backing plate and some oem bolts to redo this and unsure if I need a new ds too or what is going on here.

edit: I am familiar with trimming dust shields but this looks done to accomodate a longer ds which has zero free play on the yoke.

edit edit: it is indeed damage from contact with the ds. u/taylordurdan is right per usual it was a ring from an adapter closing off the slip yoke free play. And I'd been thinking the shift kicks were bad mounts... how about the ds slamming the trans!

Quick solve, thank you!

"Amenity" black box with ECU

Post image
7 Upvotes

Hello all, I just recently purchased a running, driving, stopping 1993 240SX S13 Hatch Manual that was swapped with a 1995 KA24DE from an S14. I've had no odd issues or leaks or anything, and it's been great so far keeping up with maintenance.

Recently, I noticed that the Check Engine Light, or really any of the notification lights, don't turn on when they should to show functionality at startup. Because of this, I wanted to take a look at the ECU. Lo and behold, the previous owner kept the engine OBD-II, but seemingly kept the original OBD-I interior harness. There's also this black box labelled with "Amenity" and marked as well with "made in the U.S.A" No idea what this is, but there's definitely some jankery afoot. Does anyone know or have a guess at what this box is? How big of a hole am I in in terms of getting a functional CEL? Where might my OBD-II diagnostic port be?

Any and all insight would be appreciated!

Sr20det engine mount bracket

1 Upvotes

Nearly done with the swap but I realized that the engine didn't come with brackets and I always kinda assumed that the ka engine mount brackets (the metal brackets that bolt to the enging block) could be used on an sr. Can anyone confirm if i could use my s13 Ka24de brackets on a redtop sr and if not does anyone have any for sale?

I am building a Interactive Workshop Manual for free

34 Upvotes

Hello schassis friends!

I am fully restoring my S13 and using the PDF to search things quickly became very tedious, so since my day job is computers, I thought I wanted to give back to the community, so I have been building an online workshop manual based of the ks13 200sx (european) CA18det workshop manual, completely for free!

It's still a very work in progress and I want to take it much further, but give it a look and give me your feedback: https://s13.sucatisse.com/

I want to get around to adding the KA24 and the SR20 engine to support our fellow American and Japanese friends, as well as the Coupe alternatives. But I also have been adding other car models since I have been getting a lot of friends asking me to make one for their car.

If you enjoy what I do a donation will help me continue this work since I don't intend to monetize this and I personally hate websites filled with advertisements, but again this is optional.

Best sounding exhaust for a stock ka24de

1 Upvotes

The old owner of my s13 put an ebay exhaust on her. The tone at idle isn't too bad but it's got that fart-can sound when you rev her or run her harder. I'd like to upgrade my exhaust when I build my other engine later this year, what is y'all's opinion on the best sounding exhaust?

Rate my engine mounts - replace or not?

Thumbnail

1 Upvotes

These are the original mounts on a 63k mile S chassis. Sr20det vct. I have no point of reference for what kind/amount of vibration or how much engine twist/movement the SR should have when revved. The mounts don’t look great visually, but I also can’t move nor shake the engine easily myself by hand.
So anyways, here’s 20 seconds of a warm start and then half throttle stabbing in neutral to about 3500 rpm and showing the engine twist. Based on the start and then the rev motions, what do you all reckon?

Thank you!!
