Why does all of my SOHC ECU's power up and none of my DOHC ECU's power up and its a New KA24DE swap and everything on the wiring was followed correctly. Have started the motor with an SOHC ECU but will not run right

You can also have the little rod between the booster and the master slightly dragging, but it's unlikely if it worked for a while. Just a quarter turn off may reduce the drag.

Aside from that the only way to reduce pad taper is to run a 4 piston caliper (or a caliper with no slider pins), and then find the right compound to fit driving. Even on my car with the Carbotech XP12s, I get a slight bit of taper on the leading edge, but that is to be expected as I'm jumping on the brakes at 120. Now the Bobcat street compound I run has no taper, but I'm also quite nice to them (aside from the spirited back road beatings

He's running EBC yellows on stock calipers.
He loves them. When i redo his pad/rotors again ill check the slide pins and MC. Thanks

is removing solid lifters the same as removing regular lifters where you just pull them out?

HipHopHippo · 07-09-2013, 12:31 AM

also, any ideas on how to remove a lifter with a broken off head? haha

ricefrier · 07-09-2013, 12:52 AM

Alright I'm new to this but heres my question im in dire need of help and want to order a maf tonight. I've got my 1989 240sx with the sr20det s13 redtop motor. I had the ka24de maf sensor which you can't run thus why it was running like shit. I'm not getting a z32 because I don't have the money to tune it right now. I'm going with a ka24e maf but will my ka24de clip fit this maf so i dont have to rewire it? I also am having trouble really finding any ka24e maf's or sr20det mafs even. I need help!!!

I think it says search first.

They have shims under them, make sure you keep them with the lifter they came from. you may also need to check valve clearances and replace shims where necessary.

I'm still trying to figure out how you broke a lifter...mystified

You may have to, yeah, you have to disassemble your head

If lifters just pull out then I doubt that, its just a matter of getting a grip on the lifter to be able to pull hard enough to get it out

oscarsx · 07-09-2013, 09:11 AM

Anyone tell me what this piece is? Ka24de

oscarsx · 07-09-2013, 05:28 PM

It think it might have something to do with the evap system, anyone confirm?

e5s4y · 07-09-2013, 06:37 PM

code 11 and 21. 11 is CAS, 21 is ignition circuit. How do i go about fixing them? Car starts and drives ok, just suuuuper bogged down under load until it gets to about 5k. pretty annoying to deal with. last i checked timing was at 13* and all sensors checked out good, but that was about 8 months or so ago. Car has felt the same since then, just never really bothered to fix it until now. Will get it on a consult and write down all the numbers and whatnot to help, just seeing what suggestions people have

slow40sx · 07-09-2013, 08:34 PM

I have a rhom tune ecu for my red top SR 550cc injectors t28 z maf and all that, but my ecu is tuned for all that plus 9:1 .020 bore pistons, my question is if I run that tune with a stock SR bottom is that a no go or will it still work properly??? Cause its tuned for that set up but the only difference will be stock bore and compression, I just don't know if that's enough of a difference to where I wouldn't be able to enjoy the car or possibly blow it up

If the new setup is using the same injectors and MAF it should work just fine.

ok so in this video what type of wire connectors is he using? male? female? SOMEONE PLEASE HELP! thanks!

13.4 is *way* too lean at WOT and past 4k RPM

For the reply codyace, maf is always in the same position since the wiring is exactly the length. It's facing the right way, filter has a new green hks element. It feels better with the HKS but the lean condition scared me so I took it off. Not sure why it's so lean under boost.

unnaturalsniper · 07-10-2013, 06:20 AM

alright.. so ive been searching google for the answer to this question.. like ive stated earlier, ive decided to buy a sr20. NOW my question is can you stroke it and still boost it? or is it dangerous to do so? im just curious if stroking it increases compression ratio? i know that you cant have high compression with boosted motors.. any help would be awesome.. just putting a list together for when i get home from afghan for the motor im building.

Lifters:

are NOT a part of this assembly

As you can see, disassembling the head, ie removing the cams, allows shims and buckets(improperly labeled as lifters in the photo diagram) to be removed so valve springs retainers can be removed and valves can be removed.

If you broke a 'bucket' that is under a shim, you are doing something wrong, or half assing the job by not taking the proper steps

I have an sr20, and what I broke is definitely a lifter. But I already got it out

I stumble across quite a lot of sr20vet's and I want to know what are the differences between a normal det head and a ve one, why people use ve instead?

Perfect Balance · 07-10-2013, 11:18 AM

Can someone tell me where the factory plug for the a/c condenser fan is for an s13? I'm trying to wire up the high speed on my altima fans to the a/c circuit and have it cut on with the switch, but when I did my sr swap I tucked away the wiring somewhere and I don't know where I'm supposed to even look. Also if someone has a picture of the actual plug that would be helpful too.

acslater9 · 07-10-2013, 12:26 PM

Confused noobie here.

I have a belt on my car that is off track how would I go about putting it back on track? Can I loosen the idler pully to fix it?

Ackaraseav · 07-10-2013, 01:29 PM

Up by the passenger head lamp. Should be near (on top of) that mass of wires coming from your fuse box up there.
