4g63t?

[nate97GSX]

I am soon to be replacing the trans in my 97 GSX and I found the best price from a place called JDM Engine Depot in NJ. Anyone bought anything from them? Anyways, the trans they have are JDM from 95-99 4G63T. I always thought the engine was just 4G63, and the T must just stand for turbo. Will this match up with my car? Oh, and it comes with a transfer case and shift linkage. Here is the link.....

yea..the t just means turbo..cause they made the 4g63 in a n/a version too..it should all hook up since the tranny and motor are the same model

I think the final drive gear ratio is different, and can not be used with your stock rear end.

 

[nate97GSX]

Yeah, I have heard that they used the 4G63 in older models for n/a. Thanks

I think the final drive gear ratio is different, and can not be used with your stock rear end.

the JDM Engine Depot said it came out of a JDM 95-99 and the spline was either 21 or 23. What is the spine of the 97 GSX?

 

[nate97GSX]

It also come with the transfer case. That should hook up to my drive shaft right?

 

[jeremy19984g63]

23, but i think the jdm transmission has a different final drive ratio.

 

[nate97GSX]

23, but i think the jdm transmission has a different final drive ratio.

So basically I cant use a JDM trans?

 

[jeremy19984g63]

This tranny must have came out of an evo III because there is no jdm eclipse. So, if so then no it will not work.

Yeah, I was skeptical about the trans being JDM cause the eclipse is and American car, but he said that they made the car over there and it was called a Talon.

 

[jeremy19984g63]

Not true!

Well if that is the kind of information they are giving out I don't think you should do any business with them.

There is a really great page that compares all of the gear ratios between different years and cars but I forgot it. Maybe someone has it.

The key thing to remember with AWD is that your final drive must match with your rear end gearing or you will kill the center diff in no time.

Look at the post below for link. Thanks jeremy19984g63.

You are exactly right, however I am sure they cant tell me the gear ratios, but what they did tell me about the trans and transfer case is that it is JDM, 23 spline, 4G63T and they said it would fit my application. But they are salesmen. Does anyone know of anywhere in the mid Atlantic where I could get a trans for under 1000

 

[jeremy19984g63]

No I don't because I always rebuild them myself.

 

[nate97GSX]

Yeah, well mine has a hole in it haha.

 

[jeremy19984g63]

have fixed that too. The good old tig!

 

[jeremy19984g63]

Or you can buy the case from TRE.

 

[nate97GSX]

Thats a good idea, it only has 800 miles on it and a gear broke inside from normal driving. Third and forth disappeared. Good old Mitsu RM parts.

 

[jeremy19984g63]

It would be an easy fix. If you can not tig or are not able to get it welded, then buy the case and do the work yourself. You would save a lot of money!

 

[stocker97tsi]

i would go with tre

Thanks for the help guys. I am going to pull mine out and see about just getting it rebuilt to stage 2 with TRE.
