My 87 t2 quit running before i left for a few months, engine has been pulled. Anyway this place that sells JSPEC engines is asking the same price for an s5 motor, tranny , harness, ecu, and intercooler with all accesories(turnkey) as an s4. So i wanted to know, besides the harness and ecu, is there anything else i need to change on my car to make s5 capable. Someone tells me about oil lines. Maybe the whole oil cooler has to be changed. ANy help lovely.

Icemark

you would change and use the S4 engine harness, a few electrical plugs on the engine (Alt for example), ECU, MOP and front cover, you may also need to change the injectors.

FC oil coolers were the same regardles of year.

Well, the engine is a complete package. Harness and ECU come connected. Everything is built im not putting the intake and stuff from my s4 13b on the s5 13b you know what i mean. This motor comes ready to bolt in and start. Unless you were refering to using my s4 ecu, alont with the s5 injectors i guess i understand.

Youll see how it comes THanks alot for the help by the way

The Jspec S5 engine harness will not fit, nor plug into a US spec S4 car.

So, you can waste your time and mess with electrical connections from here to the next year, and might get it to work, or you can do it the right way, (well as right as it can be with the wrong series motor) and use the S4 electrical, MOP, injectors (if you have a pre 87.5 model), etc.

and I didn't say use the S4 intake... I don;t think you read my first reply in your thread

You dont have to be rude im asking cause i DONt know, i was refering to your injector statment. Obviouslyy I read it or I wouldnt be talking to you. ANyway sorry for all that confusion. What part of the harness DOESNT "fit" I mean whats to it on the car side besides going threw the fire wall and connecting to the ecu udne the dash?
My harness is so fried and beat and butt coneected when I got the car that was a major problem. The harness, thats why i was going to purchase the motor with harness. --MOP? ---Is it worth the power and reliability to get the S5 motor.im assuming I am changing the MOP or whatever as well as the injectors to coinside with the S4 ECU?

My engine is GONE... I have nothing but a body with a harness in it.

Also to use the S5 intakes, you have to put your S4 throttle body on it too, along with your injectors too. YOu have to swap the front cover to be able to use your metering oil pump(MOP) from you car since it's mechanical instead of been electronic like the s5 one.

Icemark

Yeah you did: you said:

Not being rude at all, just saying that what you are trying won't work plug and play and will require custom wiring.

Again the S5 JDM engine harness won't plug into a S4 car. It is the wrong length, wired entirly different, has different plugs, etc. These are more than the harness going into the car in a different spot. These are things like parts of the plug not even matching up (even if you moved pins in the plugs- because the plugs are a differnt config).

And there is no additional reliability to the S5 Turbo motor over a S4. Either way with a JDM motor I doubt it will last 30K miles without needing rebuilding. Most don't last 10K miles.

And injectors need to match to the ECU and harness you are using. As far as the MOP, you would need to use the MOP based on the ECU you are using.

But it would be easier to run an aftermarket ECU than try and make a JDM S5 ECU and engine harness work on a S4 car.

I appolagize. Im pretty mechanically inclined, but IM really trying to see the clear picture here. IF its a J Spec to american difference it sounds to me as if it doesnt matter if I get the s4 or s5 motor. Its not going to fit because what im understanding is all the other plugs on the harness(that go to the car, not the engine) dont match up to where the components are attached inside the engine bay? I mean if you look from the front of the car, theeres a harness comming from the firewall on the left side. All those plugs meet up to the engine. But If I had the s5 motor, which has everything connected, except for the end that goes into the fire wall wheres the stipulation? Maybe Im confused as to this harness being one big piece(the harness that comes out the right side and the left side) Being so... It sounds to me a Jspec engine is the bad way to go. 1400 well wasted. My budget is not high but is there turn key engines i can order a spec(s5) to fit in my car. As far as the MOP and "front cover" which im not familiar with if thats ON the engine or on the car I would assume it would already be on the engine correct? I had 3500 dollars to get this car back together. Ive spent almost a grand painting the car, new fenders, parts blah blah. I need a new exhaust anything desent I was hoping for the racing beat performance exhaust costing at over 800 At leaves me about 1600 for engine. Can this be done. These jspec motors at http://www.jspecautosports.com/ Supposably already have 30-40 thousand. i deffianlty CANT afford for this to blow in 10,000. Since I dont have any accesories, or the money to purchase them, buying a reman motor at 2000 dollors was out of the question because of the fact that its just the short block. I dont even wanna deal with the whole upper part of the engine(intake, fuel, VACUME!!!) I remember working on the motor before and close to the fire wall all those little vacume hoses you couldnt see where they were suppose to go and the fit onto floating plastic nipples(not stationary) so I could never figure them out, take pictures, ask questions, or even get them on half the time. This J spec motor was suppose to come with tranny and ecu and harness complete ready to start but My tranny is fine i guess. So IM looking for a engine complete. I mostly wanted the s5 because of the higher horsepower, lighter rotors, I heard that they were a lil more road worthy cause of the new MOPs and what not. I appreciate ALL the help alot thank you very much. Help with a motor for this car and Ill be set THANKS

A jspec motor is probably fine if you expect to sell the car soon, or don't plan on driving many miles.

But remember they come from wrecked 15 + year old cars that have generally been sitting for at least 10 years in the bottom of a junk yard. They usually make Ok cores for rebuilding, but I have yet to hear of one making it more than 30K miles without needing to be replaced or rebuilt.

If the only reason you are going with a S5 motor is the minimal extra power, you should have stuck with the correct series for your car (a S4) motor. It would have been 1000% easier to get working. Then you could have used the correct ECU and harness to match up easier to the car's harnesses. As far as your "not getting" it, It sounds like you are getting over your head. This is not some lame honda that uses the same harness regardless of motor. The S4 different year turbo motors and cars are wired different than 89+ year turbo motors and cars.

Now if you had a S4 Jspec, then then Jspec motor would have gone in easier, and the plugs in the car would at least match, so you would be doing minimal re-wireing and just have to stash a bunch of extra wire. But going with the S5 harness and ECU, NONE OF THE PLUGS MATCH.

I am not talking just about the engine plugs, but also the dash, front, and interior harness plugs that the engine harness plugs into. I don't know how to say this more clearly. The different series do not plug in together. Again it is not some lame Honda swap.

The S5 MOP and front cover will need to be replaced if you use a S4 ECU, as a S4 ECU does not have the output for a electric MOP.

So again, if you are stuck with the wrong motor, and you want the simplest swap, you need to swap the front cover and MOP from your old S4 Turbo motor, onto the new S5 motor, use the old US spec Turbo harness (that would plug into all the dash harnesses and front harnesses). If you had originally a pre-87.5 motor then you will also want to swap the old S4 injectors onto the new motor. If you had a 87.5 and later then you can just take the injector plugs from the Jspec harness and replace the plugs on the old S4 harness with the Jspec plugs and use the S5 injectors.

If you still are not getting this, then you need to sell the car, because you won't ever get it running.

No I got it fine. Im obviouslyy never getting rid of the car. I think your misunderstanding I havnt bought any engine yet. This is why im doin reserch before i drop the 2 grand to get one. ANYWAY i contacted rotaryrevoltion i assume ill get an email tommorow. See what kind of deal he can work with me cause all i have is the short block and loose long block accesories. But he says on the page he doesnt take them like that but i dont have bolts and **** to put it back together. I dont want to buy an engine just for a core when I got one.I might end up having to go to the junk yard, getting bolts and pieceing it back together best i can. Cause i plan on having all emmisions removed and premix conversion . Thanks for the help hopefully rewvoultions can tighten me up

You may sell it someday. And check out: http://www.rotaryresurrection.com/ for engine rebuilds.

Yeaht he problem is that I only have a short block. And i need a long block. But i want a rebuild.
