JDM 4g63 engine swap

[wheelznorth_jim]

My engine in my 1998 eclipse gsx tooka dirt nap.

I bought an engine from jdmaddiction on ebay, and I am running into some install issues.

can someone please help.

1) quite a few wires have different ends, does anyone have a JDM wiring diagram ?

2) The engine I bought was listed as a drop in for 95-99 eclipses. if so, why does it not have the cam sensor on the passenger side of the engine?

3) The turbos are different


please, anyone give me a hand here....

It looks like he at least has a jdm intake on it since it doesn't bend like the 2g's. Does the 1g have a bent intake manifold pipe stock? Becasue I don't quite remember.

You don't need an evo3 ecu just use the one you already have. I just finished doing a jdm engine swap on my boy's 91 talon awd. It was a 1g automatic gvr4 engine w/ a cyclone mani on it. The only electrical difference on the engine was a different plug on the ignition pre-amp and a completely different throttle body assembly. We just used the throttle body and tps sensor off a usdm engine it bolts right up without a problem also if it's a gvr4 you might want to swap the piece that the oil filter screws into with a usdm part. The early (and maybe later) models didn't use an external oil cooler.

I bought the same motor for my 2g talon, it wasnt a bad swap. just some small stuff. Runs real strong except for the idle is rough after i did a rebuild. yea i wish i knew what size injectors came on these motors?

 

[sd_ff22]

the first pic in this thread is of an RVR motor.
About the only good thing that comes with them is the Intake manifold. It is ALMOST identical to the EVO 1-3 IM. RVRs are also 7bolts just like the 1-3 EVOs.
but that throttle body with the cable actuator on the front is a dead givaway. that and the td04.

Yep, 6 bolt^^^

 

[16G AWD]

see thats the weird thing for me because my motor was the same one in the first pic but my motor came with the cyclone intake manifold. did any of your did with the rvr motor? im trying to figure out where our motors came from. It looks like those rvr motors came with a copper or dull colored valve cover.

 

[BlackSunshine]

I have the same issue. I also have lots of pics of my two engines. can anyone help me through this?

Thansk,

[BlackSunshine]

Mine is 7 bolt, I counted...

Cheers,

Im gonna throw my 2cents in too. I have the same damn motor. One thing I haven't seen mentioned is the intake cam gear. Due to the CAS being on the cam gear side, I was told that I should change out the intake cam gear and cam itself; use the passenger CAS off my old motor; use my original intake; blah blah blah. So thats just a few things. And yes, my cover has a copper tint to it as well. So besides changing those few things, anyone else have any ideas?

 

[dsm_Prince]

i got the same engine no wonder it was kind of a ride to swap it. I got it of tigerjapanese.com. I had to change the intake manisfold, Alternator, and take off that 13g and put my bigger t25. The injectors are the same as a manual trans car. I had to take that ring of that came where the tranny would go since my car is 5-speed. I cost me 1300 shipped. Less than 45k on the engine.

Hi my name is Joel.
I have a 2Ga AWD AT with a blown engine.
I have found a very well priced engine which I belien to be off of the RVR, and the same as the egnine you folks are reffering to.

I have not purchased it yet.

I will not be doing the swap myself, the mechanic who is knows turbos and awd but not dsm.

Some say this swap is simple. Others have no end of problems.

I understand that all parts from the OEM engine must be move to the JDM engine.

Which ECU should be used.
Is there going to be a problem with the CAS.
How many extra hours will the mechanic have to spend compared to a straight swap.
Is changing turbo's worth while.
What else do I need to know?

Please help me, this car going down is simply devastating for me and my daughter.

Don't get taken for a ride.
Do your home work.
These "JAY DEE... UM?" shops will sell you anything so long as you are giving them money. Make sure you Know what it is you are getting. An RVR motor is no better than a stock 2Ga motor. Same cams, same CAS, smaller turbo, but with an evo 1-3 Intake manifold bored to 52mm instead of 60mm.

Has anyone ever done this swap and actually had their vehicle running?? I was basically done with my swap (same jdm 7 bolt from a 95 to 96) into a 97 gs-t, and had everything installed until i accidently broke the cam angle sensor off of the intake camshaft ( that originally came from the 97 4g63). Its the only thing thats keeping me from starting the car.

 

[dsm_Prince]

yea my car is running with this engine

 

[95redturboawd]

Want to take the JDM manifold I got when I bought my car off my hands?

 

[kwbunn]

One thing I definitely know - it's not a GVR4 motor. I have one- automatic flex plate with a 13G.

 

[16G AWD]

My car has this motor and it runs strong as hell! I have an evo316g on right now with supporting mods and its ready for a tune. The swap is easy,

Yes I have an Evo III Engine in mine. I picked mine up from Osaka Motors in montreal Canada. They were great, I got to walk through the warehouse and pick the engine I wanted, luckily I knew what to look for in an Evo III engine such as 7 bolts, black top CAS, injectors turbo, intake manifold. You can also tell from the Oil Filter housing because it has provisions for an external oil cooler. Getting a "JDM" motor running in our cars is no harder then a simple 6 bolt swap.

I know this is going to be a newbie question. But this is the Newbie forum so sue me. What makes the JDM motor so much better that everyone and their brother is swithing to them? I know my old Ford Probe had a JDM motor swap possibility and I even ordered it when i blew the motor. The compression ratio was differant and a few other things. But what is such a big deal if all these parts swap over? I dont get it.

Rice boys will think you are cooler.
There is nothing about them that makes them worth the money they cost to by or install. yes there are lots of good parts you can get from evo 1-3s if you are a 7bolt and galantvr4s if you are a 6 bolt, but NOTHING that makes the whole engine and the "Jay dee um" worth it.

 

[Oppi]

I dont know if there is any difference in the actual size of the cam lobes, i measured both the jdm intake cam and they are the same as the usdm one. However, i did not switch over the exhaust camshaft. would it really matter??

 

[Chrispy0530]

Bumping the thread here a bit.. I'm kinda new here. (I know this thread is a bit old too.. sorry )

I recently did this swap with a buddy and the engine is running pretty good. Now I've been running it without the compressor for quite a while because the compressor itself didn't come with the cables that were needed, and I can't pull the cable off of another 2g from a junk yard cause it doesn't match up.

I've searched a lot for this and I can't seem to find anything that helps. I'm going to be driving to Orlando soon and I would like AC badly . Riding in 90 degree weather or driving while raining with no AC = no fun.

BUMP!

i just bought an engine threw tigerjapanese because iam rebuilding my 2g talon and
so far i feel lied to because engine they said it would be an EVO III engine
but when i got it from what ive seen its a automatic RVR engine with a 13g turbo witch is like a untuned evo3 motor when i got it every cable and tubing was cut and the timing cover was cracked but when inspecting the valve cover inside oil cape was very clean as if it was oil was changed often. I havent installed it yet ive heard mixed things from ppl buying from tiger but from my experience these guys dont know anything about the engines they are selling but i plan on changing just about everything other than the block
its very easy to tune this into an evo 3 engine just like its easy to tune a wrx close to sti standerds all you would need to do is get a evoiii turbo kit that comes with manafold, 02 housing, oil and coolent lines and buy some 550cc injectors and tune ## car
= ## all set its all pretty much the same stuff if any of u guys have questions or advice let me know iam trying to learn as much about 4g63 engines and unique mods and share with DSMer's email me at [email protected]

 

[DSM98GSX]

Dont know how far you are on your swap, and just giving you a heads up. I also received the same motor when I did mine. I had to use my intake mani and most of my wiring and everything else. The guys didnt seem knowledgeable when I told them that this was not a direct replacement as they had stated. After a few things were switched, the motor did go in good.

 

[Oppi]

Bump
Update, got the 4g63 up and running about 6 months ago. Kinda embarrassed but the timing was off by a few. But, good news is that it runs like a champ. Sorry got deployed and never had time to stop by and say hi. Hopefully with deployment money, can get some upgrades.
