What's the difference between the JDM GA16DA and the USD GA16DE

 

[Adam]

It's got more power, but I'm not sure exactly how, better head design, higher compression, I don't exactly know. I think I remember seeing it's got something like 130hp at the flywheel though. There was a discussion on the regular performance mailing list, check the archives there maybe.

I think it had higher compression because of the higher octane fuel in Japan. I think the JDM version had less emissions equipment too, but not sure.

it has more HP but overall i dont think its worth swapping..might as well go with an sr20de or if you really want some power a DET

 

[LIUSPEED]

What is the US GA16DE original Horsepower to begin with? 110 ?

 

[barnoun]

110hp on the '91-94 and 115hp on the '95-99.

But swapping that Ga16de would be very simple and very cheap compared to any SR engine. It would be as simple as getting the engne, maybe the ecu, and just drop it in. An SR swap is a lot more expensive and complicated, you'll need the engine, transmission, ecu, wiring harness, halfshafts, etc....etc.

i think it's 9.9 compared to our 9.5

what car does the jdm ga16de have? the sunny?

 

[James]

ya the sunny.

What do u guys think about swapping some JDM parts into our US spec GAs? How about those higher compression pistons or the better flowing head? Only if it's cheaper than having the mods done to our parts in the US. Do you think it will be worth it?

If I was to dig into the engine to raise compression and modify the head, I'd just do it with parts available in the US, like forged pistons and a DPR head. Less hassle getting the parts and more power gain(the JDM has what, only 15hp more than the US version).

sr20de and DET
what's the difference?

 

[wes]

It's all in the T

T on the end = turbo!

well it's a pretty good idea. the only thing is the egr system... i don't think the JDM have the same emissions equipment as us...

Once the JDM engine is in. The next problem would be getting parts. Aftermarket and Stock. Most Parts people are dumb enough, just imagine trying to get Japanese parts from Nissan. Isn't that an oxymoron or something?

That's not a problem. JDM just means it's sold over there. We have the GA16DE here too so you can get all the same parts at your local Nissan, other than the slight differences that is. say you need a spark plug, a PCV valve, a oil filter... those things are all the same... now if you need a new exhaust valve(s), then you'll have more trouble.

 

[Teknokid]

Where would we be able to get a JDM spec GA16 at anyways?? And for how much?? For the cost of the engine and the ECU you could probably buy enough parts to get you those 15 HP so in the end it wouldnt be worth it.

JDM

also about the expected power gain, would japanese high octane fuel have a very significant effect?? and if the jdm engine is compatible with the current us spec harness? or if it will, but very doubtful, pass state emissions???

 

[rios]

the intake manifold would fit from a jdm to us spec right?
