Gearbox advice needed Classic wagon

[tehlukey]

Does the 6speed from the later impreza fit onto wrx classic? 

 

If not, would I need to buy a new rear diff if I upgraded to the type RA box with lsd? 

 

Don't want to be sticking same gearbox back in once it's out, I'd rather upgrade any advice would be appreciated cheers 👍

If you give your existing gearbox ty##$ code a Google to get the ratio. Then find a 6 speed with the same ratio ,all you'll need for a classic 6 speed conversion is ....

Box.

Cradle with mounts .

Gear stick and linkage .

If it's a pre 04 6 speed .

 

As the 5 speed starter motor ,fly , clutch slave and clutch are compatible.

 

If it's a late 04 onwards box you'll also need a stub axle conversion kit (from icp ) to convert the box to take the earlier "female" driveshafts [emoji6]

Thanks for that matey 👍 

Think I'll stick 5speed ha, any idea if I'll need new rear diff with type RA box? 

 

[savage bulldogs]

As long as the ratios are the same any 5 speed will mate up and work fine with your existing rear diff . Just bear in mind the classic 5 speeds are getting on a bit and even when low mileage, they tend to spit they're dummy out at 330hp ish .

 

The later bug and blobeye 5 speeds tend to handle a bit more power (360hp ish) . So are a good upgrade compared to the weaker classic boxes [emoji6]

[tehlukey]

Mines at 310 at the minute but was hoping to turn boost up and remap. The 5speed bug and blob just straight fit onto classic then of sill I need the cradle etc?? 

[savage bulldogs]

Fairly sure it's a straight swap afaik the only real difference between the classic and bugeye onwards boxes is the casings are stronger/bigger . so there's possibly a difference between cradles as the 5 speed gearbox mounts are the same throughout the impreza turbo range .

 

If you buy a bug onwards box try asking the seller before you buy , as i personally upgraded to a 6 speed and don't like to advise anyone to do anything I haven't personally done .

[tehlukey]

Ideally I'd like to do a 6speed swap but whats my issue is where to find the parts to do it and source them right as I've literally 0 idea when it comes to subaru. Never owned one in my life

[tehlukey]

Just seen a price. I ain't paying 1k for a 6speed haha. So 5speed it is. Pre 04 any will do jobby 

[savage bulldogs]

Try Matty b at mbdevelopments he's got a f.b page and has a good rep for second hand scooby bits .

 

Even if he hasn't got 1 in stock he'll probably be able to help you with what parts are needed for the newage 5 speed conversion

[tehlukey]

Nice one mate appreciate that 👍👍

[tehlukey]

My gearbox is TY752VB3FA. Found one that's TY752VN3BA

Will that fit? It's from a wrx also? 

[savage bulldogs]

If the ratios are the same it will fit [emoji6]

 

Even if your scoob has a early mechanical Speedo drive and the box has electric ,they're interchangeable .

 

 

[tehlukey]

Just wanting to fix it and sell it so liking for the least amount of hassle as poss lol

[tehlukey]

How would I find out ratio? Google sending me over the edge with all these wiki links

[savage bulldogs]

Have a squint on here to see if the final ratios match with your existing ratio . If they dont you'll have to change the diff too (which can be a ballache If it's not been removed before)

Hopefully your codes will be on there [emoji848]

[tehlukey]

Real novice question here, but does every gear have to match up perfectly? This is very new territory for me 😵

[savage bulldogs]

Just the final drive needs to be the same on diff and box bud

[tehlukey]

TR and FD on mine and the one I'm buying are 1.000 & 4.111

 

Whatever the hell that means

[tehlukey]

Oh that's it then!! Thank God for that

[savage bulldogs]

Just make sure that your comparing the ty number on both boxes and no the 1 on your scoobs id plaque .

 

Just in case your scoobs had a box n diff replacement at some point .

 

Best of luck and keep us posted how you get on ,fella

[tehlukey]

Didn't think of that 😂 can I see my gearbox code from engine bay? 

 

Ps appreciate the help mate 

👍

[savage bulldogs]

There should be a white sticker with the ty number on the bellhousing near the starter motor

[savage bulldogs]

Only pic I've got to hand the ty code is slightly lower than the sticker in the pic

[tehlukey]

Nice one I'll have a look now cheers! Very easy on the eye that bay by the way 👍

That was my first attempt at a shiney bay in my v3 uk turbo [emoji16]

This is the current v1sti's bay ,i like em clean [emoji6]

 

If you've not removed a classic scooby box before give it a search before you start , cos you have to remove the clutch fork pivot pin to split the engine and box [emoji6]
