my jdm pistons say 63TR

[pj91gsx]

I just took my Jdm swap apart and saw that the piston say 63TR. Any one know about them. The motor I have is the Tuned by AMG engine from a Galant.

Its a non turbo with higher compression pistons 10.4:1

mine is turbocharged though. Tuned by Amg. It also came with a 16g.

 

[pj91gsx]

So, would the compression ratio be like 2nd gen pistons? By the way it actually say 63DTR.
I wouldnt think it would have 10:4:1 in a Turbo charged car.

 

[tqmx1]

I might be way off base but I bet the 63DT would be the standard piston and the R would make it a factory replacement unit.

 

[synthetek]

Then its probably not really from the AMG tuned Galant those were non turbo. How do you know its the AMG tuned motor? Unless someone changed the pistons to low compression & added the turbo to it.

I bought it from Nagasaki Japanese motors on ebay. It is supposed to have like 235 hp. I cant find another motor like the one I have. The motor came with the spark plug wire cover that says "Tuned by Amg"

I have seen those covers on ebay several times, someone probably just put that cover on there. Is the engine 6 bolt or 7 bolt? Its probably an EVO or Galant VR4 engine. What kind of 16g? big, small , EVOIII ? 63DT is what 1g pistons say and 2g say 63DTF1 I think the T in the #s means turbn another site a saw a reference to a 63DTR piston in a Galant VR4 if the engine is 6 bolt I would guess thats most likely what it is.

The motor is a 6 bolt. I know it did come out of a galant tuned by amg. but I know it is not just a regular jdm swap. The intake elbow 2 1/4 inch, so it is bigger than other six bolts. The intake manifold says "Turbo Intercooler". I dont know my 16g's very well, but the wastegate dump is ported and the wheel is obviously a 16g wheel. it is a little bigger than a stock 14 b housing. Also it came with an AWD tranny and transfer case. And 510 yellow top injectors. and ngk spark plugs and wires.

AMG has NEVER done a turbo tuned car.

 

[pj91gsx]

oh. well, then I will post some pictures on here to show you all.

 

[pj91gsx]

I got a couple of parts from my swap together. I'm not going to pile every piece of the motor in the picture.

 

[Twinky-Ninja]

Not sure about the pistons, but that is a Big 16G. Judging from the dual runners, it looks like the manifold is similar to the cyclone.

 

[pj91gsx]

really? how do you know it is a big 16g.

 

[pj91gsx]

ok. I know that the intake manifold has valves inside the ports for vaccum lines. at least that is what I see.

 

[Twinky-Ninja]

The stamping on the housing (49178-01420) identifies it as a Big 16G. the 91-91 RS version motors came with 510cc Injectors and a big 16G, although I still can't explain the valve cover and intake mani.

 

[synthetek]

49178-01420 = big16 , I think that engine is from a Galant VR4 4G63 (RS) Limited Edition 240bhp. Big Injector 510cc, Eci Multi Intake Manifold, Big 16g Turbo. TD05. It is NOT from an AMG Galant those were non turbo someone just swapped the spark plug cover It is still a nice engine, and for a turbo car you would not want the AMG engine anyway.

im confused now. So will the pistons in that motor say what mine says (63DTR). My oil cap is yellow. There is another difference. I thought my motor was really rare.

Yes 63DTR is from a Galant VR4, you do have a rare engine that one has more HP, bigger injectors, turbo etc.. than a regular VR4 engine. You cant use accessories like an oil cap and spark plug covers to identify the engine those things are easily lost, changed, etc.. The rest of the engine points to it most likely being the VR4 240HP .

 

[pj91gsx]

well. thats excellent. I have had my motor for a year and I didnt know its Identity. I'm ready to rebuild it as my drag beast.

 

[srumel]

Yupper. From what I researched a while ago, there were optional features on the GVR4s in Japan that were not available in the US, such as turbo, and engine. I believe the R in DTR is the "Rally" option designation or something like that. My JDM 6-bolt motor measured 180psi across, I have yet to pull the head, but expect to find something similar when and if I do. By the way, did you happen to perform a compression test on your motor? And if so, what were the results?

63DT is what 1g pistons say and 2g say 63DTF1 I think the T in the #s means turbn another site a saw a reference to a 63DTR piston in a Galant VR4 if the engine is 6 bolt I would guess thats most likely what it is.

Sorry to highjack, I wanted to verify the piston numbers above.
The car I bought supposedly had the 2g pistons installed, I have the head off and the crown number is 63DT-F1.

 

[pj91gsx]

I did not do a compression test before I ripped the motor apart. However I thought it was quite interesting that the wrist pins on my 63DTR's are very similar to the 2g wrist pins rather than 1g wrist pins. I think the 63DTR's have 2nd gen compression. Did you get the big 16g and yellow top injectors? was your tranny switchable between fwd and awd? Mine was not. for the other guy on this thread. I am now doing 2g pistons/ 1g rods for a friend of mine and these pistons say 63DTK. The pistons were from a 92 7 bolt. After I finish this motor I will rebuild my jdm swap.

Pistons from a 92 7 bolt are the same compression as the 1g 6 bolt pistons they are not the higher compression 2g 7 bolt pistons.

Yes 63DT F1 is a 2g piston

 

[pj91gsx]

ok. I cant explain my pistons then. I can just say that the wrist pins on the 63dtk are very similar if not the same as 63dtr. but the 63dt's have different wrist pins
