Ok guys I ran into a little problem and need help. I have a 98 gs300 and trying to swap a 2jzgte vvti engine. I went ahead and bought a supra 93-98 auto turbo drive shaft.

Can someone tell me how do I go about mix matching the supra drive shaft with my existing gs300 drive shaft to make it fit for my 2jz swap? Exactly which part of the drive shaft is used and etc?


This is my thought:
Im thinking swapping the two propeller shaft, but the supra is shorter and so is the center support bearing. If the support bearing is also shorter, how will I line it up to bolt it onto the chassis?

You don't. The just reuse the stock GS300 driveshaft. This is assuming you're using the stock rear differential. You should also be able to swap the output flange on the transmission with the one from your stock one.

You can't use the complete stock Gs driveshaft, the output shaft coming off the trans is different and the diameter of the splines on the flange is also different, if you try to swap the flange you will very quickly destroy the output shaft on the transmission. You will need the front half of the Supra shaft and the rear half of the Gs shaft. You can pull them apart in the middle and then put them together in that config, if you are worried you can then take it to get balanced at a driveshaft shop however mine was fine without.

JeffTsai,
Im using stock rear differential. Everything is still stock.

macd7919,
Can you tell me which is the front shaft and which is rear? I ask this because, the stock GS shaft is something like this...The female shaft which bolts directly after the tranny, and also has a 3 hole flange. Then follows the male shaft which also has a 3 hole flange.

The supra...The female shaft is 4 hole flange and bolts directly after the tranny. Then follows the male shaft which bolts to the rear differential and has a 3 hole flange. The only two parts that I can see as swapable are the supra shaft that bolts directly to the rear differential, and the gs300 shaft that is also bolted directly to the rear differential.

So can you tell me which shaft goes with which shaft...is it the shaft that bolts to the rear differential that I swap or the one bolted directly after the transmission?

You need to swap the front portion of the shaft that mounts to the trans. It's been a long time since I did mine but I specifically remember being bummed because the car was done and when I went to put the driveshaft in it didn't fit. Luckily I had a pike of spare driveshaft laying around and found one that fit. I just seperated the two shafts in the middle and used to appropriate side from each.

Uh oh! This doesnt make sense. My supra front shaft flange has 4 holes, while the GS has 3. Do I need to get something else? There is no way I can fit the supra shaft onto the tranny output flange. Am I missing something here?

That would def. pose a problem. I can't be too much help as when I did mine I just went through the pile until I found the appropriate shaft though I'm 100% sure the stock shaft didn't fit. If I get some time this weekend I can try to peek under my car and see if I can identify the setup I have.

I actually have a aristo transmission laying around which has the 3 bolt flange that you would need to mate it to the transmission you have now to make everything work. I'll remove it this weekend and you can do the same on your end and we'll just swap the two output flange. How's that sound? I like helping members out.

I think he already has the 3 bolt flange for the Aristo trans, the problem is that the driveshaft doesn't fit it properly, I could be wrong but the Aristo trans I had also came with a 3 bolt flange, it just didn't line up with the Gs driveshaft and the flange from the Gs trans was not the correct diameter.spline for the Aristo trans.

Thank you so much for the offer Alexus, thats really nice of you. However, my aristo engine also comes with an output flange attached to the tranny. I guess I can just use this output flange and mount it to my stock gs300 drive shaft? If thats the case then I dont need the supra drive shaft?

Oh man now I'm confused on how to make this work.

Let me list what I have and hopefully someone can tell me what I can do to make this work:
1. 2jzgte vvti aristo engine and tranny. The tranny also comes with the output flange(rubber piece).
2. 94 automatic twin turbo complete drive shaft.
This engine is going into a 1998 gs300.

Oh crap, it slipped my mind when I wrote that. Forgot the Aristo comes with the A340E lol. In that case I don't think the A650E output flange would bolt on. Good catch.

Im going to wrap up this thread and hopefully this will also help others to not make the same mistake I did. The Supra drive shaft is not useable for the 98+ gs300 swapping a 2 jzgte vvti aristo engine. It might work with a supra engine, but not an aristo.

so if i get the 98+ 2jz vvti i would need the drive shft?
