My JDM Engine Swap Begins

This will be nothing to you this is a drop in bam fasten the bolts and you're out of here It's that quick It's really not a lot to this I don't know how much plastic is already missing from your car and whatnot so there's always that but this will go very quickly in your driveway and a shop and your garage Georgia this time of year is a nice area to be outside in the driveway or even in the grass That's how I am here in South East USA myself wonderful time of year a few weeks from now you'll be wishing for this weather so I don't know if you're not starting an Ernst for a few weeks oh boy it'll be in the hundreds but still about a 1-day affair especially coming from straight six Jeeps and whatnot this will be like a breeze.

 

Oh for God's sakes you are good to go Just I guess making the time or whatever but you're in good shape got a good place to work all of that and you can take your time and sit in the chair and drink coffee and work.

 

I wish mine had gone smoothly, still can’t get the thing running right.

 

Where are you with yours what's happened Gen 4 Gen 3 to Gen 3

 

I bought a gen 3 jdm from Charlotte NC, and I cannot get it to run.

It will fire up but shakes/knocks horrendously.

Engine looks great, I’ve had camera inside the cylinders, walls look great, piston tops look great, intake valves all cleaned.

I put it all together with new plugs, and I;ve tried swapping all the sensors from my old engine which worked, I’ve cleaned egr and triple checked all the electrical and vacuum hoses, nothing seems to be out of place or disconnected but I cannot get it to run for love nor money.

I have spark, I have fuel, it will run but misfiring and making noise.

I am just about stumped as to what to do next.

 

Do you have a myriad of codes to go along with all the misfires and the nonsense going on We had a lot of this going on too and we found rusted coils and all that kind of crap We know our engine sat on the dock and it got wet with salt spray a few times things like that we can tell It looks great but you could just tell coils were rusted we changed them out for the ones that we had in the engine that messed up so all that stuff was good and fine We swapped all that over even the plugs weren't but a day or two old at 10 hours on it maybe and that straighten most everything out as far as the missing in the rough running then we had the electrical problem with the battery and once that was sorted thing ran like gangbusters for 90 or 120 days and then boom back to the rattling

 

Yes I changed over almost everything from my old engine, still no dice and I’m getting lost as to where to look next, I guess Ill go over all the wiring harness and connections again.

Do you know how far the throttle body should be opening? Im only seeing it move a very small fraction. I’ve tried two of them and both move the same.

 

We could not get the JDM throttle body to work at all I couldn't get it mixed up because it's the only one that won't work My 13 persona was in really good shape every part on the car was nice been well taken care of It just internal combustion temperature went up due to EGR clogging I guess and took out the head gasket or however all that works It's not a very nice system I do know that The two z z engine non Atkinson in Corollas does very well better than some of the other engines actually.

 

Valve timing is critical You can see the bottom mark with the front seal removed behind the pulley and the valve cover off of course You can see the marks up top I think every 9 times they line back up.

 

The question is Daley’s engine really an unmolested JDM engine that has never had its timing cover off or is it a US salvage engine with issues? Given your experience and a few others the integrity of some JDM sellers might be less than ideal.

 

There is always that risk that is a fact but generally the real JDM importers have some skin in the game and generally won't screw you over like this now these big sellers on the marketplace that claim all of this and that well they're buying from people like the real JDM suppliers and then doing I'm not sure what but whatever they can to turn a buck and that can get ugly really quickly actually. So I try to buy from the guys that are players in this game for a while and are still in business they own these little you know what places as our president called them one whole place is all across the country but that's what they do.

 

I don't know what size the fuel disconnect tool is but I have a whole rack of the Lisle branded quick disconnect tools minor colored plastic I also have some older metal ones that are quite old and there's a size that does the evap and the fuel lines on the Toyota's I do believe

 

If you got a laser level and a small ratchet strap it’s easy to align.

 

You mean aligning the engine and transmission so you can put the bolts in well I didn't know it was that bad I don't know it needs it might be easier to undo the strut tops and pick the chassis up and push it back and work everything while it's sitting on the subframe just a thought I haven't had to do this My buddy changed the one in my persona It only took him about 4 hours and he's in a makeshift shop out in the country.
