Hiya,

I have a 96 NA JDM Supra. Does anybody know what differences does it have compared to US NA versions?

Also, is there any 6-speed Supra that is not Getrag, or are all 6-speed tranny Getrag?

Thanks

Im not real sure on the differences but I do believe the JDM NA Supras are faster due to less emission devices being used.

The 6-speed for the Supras is always a Getrag. From what I hear the same Getrag 6 speed is used in the newest BMW M3s as well.

Japan had a 6speed for the NA.. that was Getrag as well

What about engine-wise?
Because, I'm thinking about turbo-ing my NA, and (if it is the same as US versions) I am thinking about following some of the paths that has been taken by you guys (e.g. copying the component list, boost rate, etc). I'm aiming for 450rwhp on the road eventually.

marmoot, what city in new zealand are you in :]?

there is a NA-T 94 in wellington, that was done with parts ordered from the states, so im assuming it will work for you man

I'm in Auckland, but I'd like to get in touch with the owner if you have the details, to see what problems he had turboing his car.
I really want to be very careful with this project since it has to last for more than 5 years (e.g. more bulletproof than powerful).

I have a sneaking suspicion that the JDM cams have slightly less lift.

Also JDM motors are MAP sensed, whereas the Seppos have an air flow meter.

the info is right under your nose mate:

Good wealth of info in that page, thanks.

But still doesn't give precise answers to my questions regarding partwise (any part difference?) direct comparison between US NA and JDM NA. And, most importantly, any experiences in doing NA-T in JDM by any of you guys? Problems and whatsoever different than guidelines made for US NA?

Any input is appreciated, however small and/or redundant it is. Thank's all


P.S.
Thanks about the info re: MAP sensors

JDM versions supposedly have smaller turbos and smaller injectors. That is the extent of my knowledge of JDM vs. US motors.

To the best of my knowledge, neither the JDM nor US spec NA Supras have turbos.

Do you mean the NA engine internals being different? If that is what you mean, then no difference.

All the Supra 6 speeds are Getrags - however I am led to believe that the turbo 6 speed is the V160 and the NA 6 speed is the V161. I can't guarantee that is correct.

 

[Marmoot]

Power-wise (durability), is there any difference between V160 and V161 getrags? Which one is weaker and by how much? I hope my getrag can withstand extended 450hp?

Also, does that info about injector difference apply to JDM NA (vs US NA)?

Thanks

 

[gianttomato]

No idea about the boxes....suffice to say they are both very strong.

As for the injectors, the 2JZGE runs 315cc/min units.

Oops! I jumped the gun before I read the thread carefully. I thought we were talking about the turbo motors. My fault!

 

[Marmoot]

But,.......aren't you in the NA forum?

About the box, "they're both pretty strong" is enough for me

Right, NA-T it is then. With TD04 probably......
