hey, searched, didnt really find what i needed.

was looking for some wiring advice on wiring the redtop into my S14, and what all i can and cant use, im getting a full front clip from an s13 and would like to use as little of wahts in it as possible.

#1 - can i use my stock S14 driveshaft with the SR?

#2 - need a page for wiring issues and trouble shooting and tips etc.

#3 - would like to know what i can and cant use, doesnt need to get in depth, just the basics

#4 - how much can i expect from parting otu the remander of my front clip? :D

and any other suggestions that you all think i may benefit from.

i am not an idiot, just looking for some basics with the swap, woudl liek to get it done quickly instead of wasting my time when i find out i can use something and have to get something else etc.

thanks!

#1 - As far as I know...yes.

#2 - http://sr20.hybrids.jp/install....html -This page covers some of the wiring issues, might not cover all. I believe the A/C has to be rewired too, but I don't have an resources on that right now.

#3 - You can use most if not all parts, but I'm sure there are a few minor parts that can't be. Maybe someone with more experience can elaborate.

#4 - Depends on what it is you are parting out and what condition they are in.

1. If your s14 comes with an automatic transmission and you want to install a SR that comes with manual, then you will need a manual driveshaft. Swapping between manual does not require you to get new driveshaft. Even between s14 and s13.

2. issanni got that one. I remember reading from HT that if you want to use s13 engines in s14, you cannot retain the A/C. The whole A/C systems in the two cars are very different. In addition, you will need to remove the cruise control if you have that on your s14. S13 throttle body doesn't come with cruise control.

3. You can use the engine, transmission, ECU, starter, etc, basically anything required for the basic engine swap. Clutch slave cylinder can be used. You might be able to use the stock s13 SMIC and piping, but it requires some modification to the piping and body. Other than those, you cannot use anything from the clip unless you have a s13. Some people use the horn from the clip, but it's your choice.

4. You can probably sell the stock pieces if they are reasonably priced and cleaned. Things such as fuse box, stock sway bar and bushings, calipers, brake rotors and lines, etc, pedal assemblies, steering parts, interior pieces, spedometer, suspension assemblies, front subframe. Radiator with fan shouds and clutch fan, if you sell them cheap, people do want them. The clutch and brake master cylinders are also pretty useful. things like washer fluid pump and wiper pump can also be sold, if someone wants them.

If your clip comes with salvagable Silvia or 180sx body parts, then you can sell those too. If you get a s13 Silvia front clip, even if it doesnt come with body panels and such, you can still make some money by selling the headlight brackets if it comes with it. In addition, the radiator support can also be sold to people who crashed their front end.

If you are living in the States, you shouldn't get a s13 front clip. I suggest getting just the SR engine. This is because if you own a s14, you cannot use most of the parts from the clip other than just the engine and transmission. If you have an old s13 240sx, it would be a great idea to get a clip since you would want to replace some old worn parts on it.

The money saved from getting just the engine could get you an intercooler kit, which is one of the most effective kit.

The s14 stock 240sx radiator is larger than the s13 SR20DET radiator, so using the s14 stock intercooler can be considered one step better the original set up.

As you can tell, I am really bored here. :(

I pulled my AC when I did the swap. Also like was said before, just get the motor do not get the clip. You will save a lot on shipping and the cost of the motor. For less than the price of a red top front clip I got a complete S13 Blacktop in great shape. Just my 2 cents.

A/C works, just gotta have it wired correctly. The reason why its a whore to most is because S14 chassis has an intermediate harness for acessories like wiper motors, abs, cruise, a/c, etc. The S13 has everything running through the main harness which makes it a simple "match the wires up and lets get going" kind of deal. Basically, check out wiring diagrams on where this intermediate harness switches over to another harness and "reroute" it manually to where the wire was destined to be linked. You will need USDM wiring info for this. When you have found out where these ends and odds go, compare with the S13 (JDM) harness wiring to see what goes where. If any match up, link those wires to it. The rest that aren't on the S13 harness must go straight to its destination, such as, console controls, cruise connectors, interior dash connectors etc. Heavy Throttle should know how to have all this stuff integrated into the S13 harness by now. Send the harness to them and make it easy on yourself. The only thing that will cause a problem is not the wiring, but the stock side mount intercooler pipes will get in the way of the KA compressor. Other then that, Heavy Throttle can make due with the harness.

well the clip is already on the way, a local shop is getting it so theres no shipping and the clip itself i am getting for 2400

so i opted for this deal, no shipping and i can part the clip out and probably get all for like 2 grand aftet parting what i dont need out, so i thought this would be the best way to go, thanks for the info. id rather do the harness myself, i dont like other people working on my car. makes the car feel less mine. im goign to ditch the cruise control, im diting the AC and the car doesnt have ABS. so all i have tot worry about are the wipers, and that should be cake. i plan to get the whole swap done in less then a week (otherwise i have no transportation and im out of both my jobs and possibly my third) so i want all experience in this post so i know exactly waht to look for and dont haev to waste any time trying to figure out stupid crap. :D

i know you guys are smart, keep it coming. i dont like surprises when working on cars on a budget and a time limit.

as far as i know the side mount cooler should go into the s14 with some cutting in the engine bay. i dont think im gign to have to modify the pipes. if i do ill stick the clip in my garage and wait to do the swap til i can afford a front mount :D

I suggest you have a beater of some sort to get to work. Sometimes, s*** happens and puts you out longer then expected. Not everything can go as planned all the time. Also, I wouldn't want to cut up the car to shove that side mount in there. Saving up for an front mount intercooler is the best way to go.

I am always bored too, and I check out your page a few times when I am bored. Damn, that's a damn nice car.

I am still in school and I will place an order on my SR as soon as I am out of school. For now, I just maintain my S14 and try to keep it in best shape, which it is not.

My set up would be:S13 (red or blacktop)Blitz Nur SpecBlitz Down pipeHT Hot pipe with Blitz BOVGT-R 34 V Spec II Intercooler with custom pipingGReddy PulleyIntake

What HP figure should I expect from this set up? This is the first round of install.

Electric fans, boost gauge, oil pressure gauge, and battery relocation will also be added.

add maybe like 10-20hp u wont gain much until u boost it up. might not want to waste money on the pulleys heard they dont so much at all.

the wiring is pretty tough to do on your own, I already have diagrams because I was going to do it myself. it doesn't matter how much you don't like other people working on your car, just send the harnesses to Heavy Throttle and have them do it. It only costs $250 and shipping both ways. It'll save you alot of headaches

You can use a KA24DE throttle body (from one that had cruise) you just need to rearrange the coolant pipes a little. And make/modify the cable bracket.

The Harness is not that hard to rewire just follow the steps on http://sr20.hybrids.jp/install....html its pretty simple to do thats how I did mine it took about 3 hours to do and it all works great :D

You guys need to work with me here. Please help me out, I really need to know what to do.

As far as I know, I must use the engine harness from my S13 SR20DET. But I dont know to plice or have ANY idea where to begine.

1. I would keep my main harness (the one that goes around the car) right? Same thing with the dash harness (from the ECU to the dash)? If not, what do I do?

2. WHere do I find the ECU pin out for SR20DET?

3. At the SR20hybrid page, it told me to use the S13 cluster plug in my S14. What does that do? Are they interchangable and I have to use those to make my cluster work?

4. Sorry, but what harness do I take out completely to do the wiring?

5. I have to cut the KA ECU harness plug and rewire in the SR ECU harness plug right?

Please contact me by any chance, I really need to have a good understand about the wiring. The SR motor is in the car, and that's pretty much all I can do until I find out the harness wirings.

This is a way bigger job thatn can be explained in a forum. I've never done it so can't help. It's doable, but those who know how, probably can't explain here eiother, even if they wanted to. As explained elsewhere in this thread Heavy Throttle and ~$250 are probably yoru best and safest bet.

For 250, i can cough it up, but I want to work on my car, and not someone else. I know it ain't hard, as long as I know what to do. Daunt, can you please answer my questions above?

Quite frankly somone who provides a service (Daunt) shouldn't be expected to spell out what to do for someone who wants to do it themselves. If your so keen on doing it yourself do the necessary research. The pinouts for the S13 ECU are all over the web, there is a S14 (200SX) wiring diagram available on many sites. There is no S13 ECCS wiring diagram available anywhere that I have ever found. You'll also need to wiring diagram for your vehicle, and the instruction on the sub harness that needs to be built that have already been discussed elsewhere in this thread.

Once you have all that then you'll need to understand it all, do some calculated guessing, lots of soldering, and hopefullyyou'll end up with something that works. If it doesn't work kthen you might fry your ECU, or god know what else, but at least you'll have done it yourself and got that satisfaction.

SHould I use the S14 KA fuse box or the SR S13 Fuse box? I'm at the point where the fuse box for the S13 in my S14 makes the most sense...

Oops, nevermind.

I followed sr20hybrid.jp and I did all the connections.

1. Now, I have tons of extra wires, which I think will not be hooked up, right?

2. On the SR engine harness, by the alternator, I see a black cap, which I think goes in to the alternator, right? If so, under my KA fuse box, there is a red cap and I think goes into the alternator, so now i have 2 connections to the alternator? What do I do?

Rather than that, my car should start up fine right? And I'm doing a S13 redtop into my 95 S14.

No offense, but with "tons of extra wires" I'd think the chances of it starting up fine are just about zero.

I've done a couple of redtop harnesses for S13's, starting with cut SR harness and stock KA harness. Both started first time and have had no wiring problems since. I've never done a redtop S13 to S14 harness, so can't be of much help there (I haven't done the legwork for this yet).
