Fabia 1.4 mpi (68hp) to 1.8t auq

[Gyenes]

Hey guys!

I started a 1.8t project on my fabia, and i stuck a little bit.

Anyone can help me a little?

So my biggest problem is the gearbox holder, because i can't fit my own holder, and i don't know, what holder should i use.

And i have one more, the halfshafts.

1.4 halfshaft are shorter than the octavia shafts, and i can't fit the swingarm.

I tried replacing the outer wrist, but it's too long yet.

Anyone can help me?

I really want to make my love running, with an 1.8t.

And sorry for my bad english, but i'm living in hungary, and i can't speak properly.

I believe @Tech1e is your best port of call, having done some mad but also amazing projects involving 1.8T engines and Fabia's of a certain age...

What gearbox are you using?

[Gyenes]

Factory 1.8t auq gearbox.

Ah that’s why then. The Octavia uses an 02J and the Fabia an 02R. The 02J is wider at the end case where the mounting goes. 

[Gyenes]

And somehow i can use the auq gearbox?

Maybe if i create a new console for the fabia holder?

yes you will have to widen the bracket. 

[Gyenes]

This is the octavia console, i think i have to a make a new console, maybe the 6l1 ibiza (1.4pdtdi maybe) console not good for me?

[Gyenes]

And what you recommend for the halfshaft?

Or i need a longer swingarm?

[Gyenes]

Hey!

My fabia, before i started the work on it.

[Gyenes]

Engine and everything i nedd for a replace, out.

[Gyenes]

I replaced the rear bridge, feom the vrs, but its wider with 3cm🤣

I have to make a wide body on the back

Its a bit dusty, but i don't have better place

[Gyenes]

[Gyenes]

Engine is in the car, but the gearbox holder not avaliable yet.

[Gyenes]

I replaced the timing, i have to reolace rhe oil, oil filter, sparks.

The buggest job is i think the electronical job...somebody know, i have to replace the dashboard?

Because the immobilizer?

Probably be a matter of cutting and splicing the wiring loom of the car amongst other things.

I have no idea about the immobiliser however.

I have ecu and wiring loom from the octavia, but i don't really know what i have to use in my car.

Becausw i have some relays too, but in my car i have relays, for the petrol pump, and idk.

Fabia is a Polo 9N platform, Octavia is a Golf platform, Golf is wider than Polo so the driveshafts are too long, driveshafts from a 1.9 or 2.0 Fabia should fit but you'll probably need the struts and hubs as well which is a good idea because then you can fit the big brakes.

[AnnoyingPentium]

Adding on what Sep said, big brakes are a necessity since you're going to be putting down more power.

[Gyenes]

Yes, i will buy the bigger brakes, next week delivers by the courier, feom a mk1 vrs fabia. This is 288mm the seller said.

And i replaced the back bridge, so i have disc brake instead of drum brakes.

So the 1.9 shafts fits good?

Because i can buy 1.9 shafts fromt the guy who sold the engine.
