Changing Gear box

[Corona]

After doing a quick search, and not finding any relevent info on here, I thought that I would ask a couple of questions.

I am replacing the gearbox in my car now that is has a few issues, too many to mention here.

The setup that I have at the moment, is I have a 3S-GTE in a ST-191. The gear box that I am using curently is I belive out of a ST-171.
I picked up a replacement E36 box the other day from a wrecker and am going to do the replacement in a couple of weeks. What I need to know is
1) Will I have any problems with the clutch plate and flywheel etc during assembly?
2) What should I do to the box before I put it in?
3) Are the driveshafts a match?
4) I notice on the box that there is an oil cooling pipe on it. Is it worth hooking that up to the now unused oil cooler that is intergrated in the Radiator? (Or would I be better using that for the engine, or turbo oil?
5) What other traps am I likley to fall into?

Thanks in advance

Oh yea the other thing that I am going to do is change the oil seals where the drive shafts go into the box

Anybody?

right...let's take this a step at a time...

firstly E36? Are you sure that's what it is? I'm going to hope it's an E153 or similar..... (E36 would be a 3 speed!). Maybe an E56? I hope it has a 3S bellhousing...what car is it out of?

1) Quite possibly. If I remember correctly Toby had to get a custom clutch made for his engine/gearbox combination. You will probably need a new clutch disk. Do you still have the spare gearbox from my old car too? Check the input shafts on that box and on your new one and see if they're the same size + number of splines. If they're not you'll probably need to get a stock 3sgte clutch disk.

2) Clean it

3) I'm going to guess that they probably aren't. You'll probably need to get mr2 turbo driveshafts and get outer cv's put on them to match your front hubs. Most likely mr2 turbo shafts with st185 celica outer cv's will do the trick, the main question being whether they're the right length. You may even find st185 front driveshafts with an mr2 turbo intermediate or supported shaft will do the trick.

4) You could hook that up to an oil cooler if you like. Wouldn't use the one in the radiator though, you'd be better off getting one from an st185 or something (I have a mate with all the hoses + cooler from an st185 if you want them)

5) Engine mounts might be different on the new box and may not swap over from your old one. Shifter cables might be different too (as far as length is concerned, fittings should be the same).

Let me know if you can find those oil seals cheaper than $35 each

Save yourself the hassle and put a standard gearbox in good conditon in.

My experiences putting an E-56 into an ST-182 Celica that comes standard with a S-53 box:

You'll need to stuff around with driveshafts... I'm never ever gonna change another cv joint or boot again. Inner joints are a different size so you'll need the shafts that were in the gearbox.

Shafts will be 20mm too long on each side because the E-56 gearbox sticks out 20mm further on each side. Total inner CV joint travel is about 40mm meaning it's a problem.

Splines on the input shaft will be different meaning you'll need a different cluch disc.

Not worth it assuming your standard gearbox is something like the celicas and your replacement box is an E-56 or similar.

Oh and some mount modification was needed

It is out of a ST202 and was origionaly hooked up to a 3S-GE, so bolting it up should be Ok.

As me and the other gear box are approx 2 hours away, I am unsure now if the splines and driveshafts will fit. Looking at it and from memory, they look the same, but might send it up to my brother in law to check the drive shafts and splines to make sure that they are the same, unless you have one I can look at?

Yeah my E-56 came out of an ST-206 curren so the one you'll be looking at will almost certainly be the same. They're the LSD boxes. I stil would'nt reccomend using it though.. Far too much hassle

[celica_tommo]

I sold the two E-56s I had when after doing all the stuff I mention above cause the cvs were clicking. Dont think I got the driveshafts modified exactly to the right length. Besides you can't legally modify the driveshafts

Himm, this is soulding not as easy as I had origionaly hoped. The origional engine change was not sounding this dificult
