you can get CA18DET FSM w/ full wiring diagrams from zilvia.net, you gots an email already there :D go to the technical session

if you mean for wiring from a CA into a 240SX, then, that's more complicated. but if you gots your FSM for your own car that'll help. Alot of it 'bolts on' if you have the whole harness, otherwise you're in for some time spendin'

Im sorry if I come off as an a$$hole, but you didnt search too well at all. In those 100+ threads you found, you would have read that the CA18DET wires up the same way as a red/black S13 SR20DET into a S13.

Heavy Throttle has a page that explains everything you need to do.

hey man, just a quick question on swap over sr20det parts.

-greddy sr20det hot pipe(aluminum), i knoe that there are steel flanges, but do they make aluminum flages so i can weld i to the aluminum hot pipe?

-greddy sr20det 3" down pipe, could this also be used for the ca18det?

-z MAFS, would i need this for hte ca18 or will the OE one work?

thanks

-Yes

-Yes, you'd have to cut and reweld the flange that connects to the o2 housing.

-You can use the Z MAF, but you need a ECU retune or an SAFC. If you have the OEM one OR an S13 SOHC one, that will work too, with out any ECU or SAFC mods. Just have to rewire the MAF plug.

Keep asking questions! This is about the only thread I have found useful....

The stock KA24DE Radiator does fit correctly, hosing and all right?

Also, does the SR20DET Downpipe have to be cut and re welded only if you are using the stock CA Turbo?

good! new guy using the search function:D you've become my new best friend for the day! lol

the KA24DE radiator and hoses all work, the hoses just need to be trimmed slightly to fit, but you can do that when the motor is in the car to see exactly what to cut:)

the SR20DET downpipe fits and fits well in my opinion. I have an SSAUTOCHROME o2 housing I got off eBay for an SR20 and a stock SR downpipe.

I will have a 3 inch SR downpipe here soon, but the stock one fits well with no issues. Some people say it sits too low, but mine's just even with my frame rail! I don't see how I would ever hit it, unless I bottom out, but that would kill my FMIC way before my downpipe:eek:

and the stock CA turbo and stock SR turbo themselves are the same dimensions (externally I mean... the SR t25 is somewhat of an upgrade over the CA turbo) so the only difference is the length and orientation of the o2 housings.

I'm online alot of evenings if you have any questions... AIM name is NeedCAforS13:)

Well inform me :).. i did all the heavythrottle wiring stuff and i put the key in, turned it, heard the fuel pump priming and the dash lights came on... but i turned it back off and pulled the key out and nothing happened, it all stayed on :). No im assuming its either the ignition wiring or when i took all my extra wires that i had stripped, twiisted them together and taped them away something in there is sending signal, i dunno man.

no clue. i never hit mine for some reason when my idiot friend revved it to 9k. and my tach isnt more than 200rpm off. now i dont have one because i have a different ecu. i think it might be 8k or 7800 or something. im not quite sure though. you should be ok if you shift before 8k. power drops off after 6400(ish) stock, so i dont see a point revving that high unless you have altered the valvetrain or have a massive turbo on it.

Well i got my first wiring problem fixed. Everything will turn off and when i turn the key to on, i hear the fuel pump go and a few dash lights come on... but now none of the other lights work. The map lights, headlights, audio system... nothing. So im gonna go back over it and undo the rest of the random wires i have hooked up and tape them seperatly but anyone have any ideas?

K, well no one is replying to me but ill keep posting anyways... Now if i hold the key to crank (no belts), the starter clicks once and has an elictrical kinda noise to it but doesnt have enough power to turn over, but then all my lights and stuff work. But, after holding on crank and checking all the lights i noticed smoke coming out of the hood. Thats not a good thing :). Is it just because i was holding it on crank forever and it not turning over or do i ahve a bigger problem?

Your engine is not grounded! You must put ground straps from the head and block to the chasis! BTW Nick, did yo pay for shipping of the manifold or did they just drop it off to you. I need to know because my girlfriend shipped it off her comany's account and she needs to know if they charged the company or shipped it C.O.D like she intended.

they shipped it cod, its was like $25 and i guess thats what the extra ground wire i had was :). But the wire i have is screwed to the intake mani, then has a battery terminal type thing on the other side... should i just cut that then tap it to some part of hte engine bay?

One end to the manifold and the other end to the chasis of the car, It is very important that this motor be grounded to the chasis or you will burn up your ecu, igniter, etc..........

Ok I know that theres a ground from the battery - terminal to the intake. and a small one from the Exhaust side of the block to the body .. is there anymore??? cos i just finish my wiring and all the warning light from the cluster i got is brake, door, and belts. no batt,oil or anything else. everything else seems to be in good working conditions. I got power to all the dash light, power window and mirror.i have no idea if i got power to the radio or not cos the car didn't come with one.

I'm just a little concern with the oil and batt warning light not coming on.

BTW what did u guys who got rid ot theirs PS system. plug the stock line and stuff???

well the only ground i have on the body right now is a little guy from the intake mani to the body and it didnt do a thing. So im going to get some 8 gauge wire and hook is somewhere on the block to the body caus i dont have lights anywhere on the car minus a few dash lights when i turn it to on. If i turn it to crank all the lights work...

Ok, i have my block, head, and fuse box grounded... the car will turn over when i turn the key but my oil system isnt sealed so im not going to try starting. But... half the electrical stuff in my car still doesnt work... i did all the wiring heavy throttle said plus 2 extra ecu wires that matched up. I have 2 black wires off the ecu not hooked up but when i grounded them nothing fixed... Am i missing something? Headlights work, starter works, clock lights up but no numbers but thats about it.
