Engine upgrade - Passat b4 enq

[78dude]

It looks like the 1.8 - 90 bhp lump I have in my Passat start to have some issues, so instead of spending time and cash to fix it - I have started to think about replace the whole thing. 90 bhp is what people have in their mopeds these days too.

On eBay I can see plenty of 2nd hand VW engines for sale, and the ppl who sell them is not asking big bucks for them as well.

I have tought about the 1.8 turbo engine (used in Golf, Passat, etc) but I'm not keen on turbos and its sounds just like a VW 4 pot engine - who means dull. (I used to have an Alfa with a V6 engine, and a BMW with a V8 to an information) So I like that a engine have some nice tones from the exhaust. So I have tought more and more about the V5 engine - mostly used in the Golf and Bora - and I have spent some time on YouTube - and the soundtrack from it, can some how make me think back on the V.A.G rally era with the UR Quattro flying intro the forest with the lovely sound of a 5 cylinder powerplant under the hood. Its sound smashing! ;D

So my question is:
When you install engine like this, do you also use the gearbox - or can I use the original gearbox on my 1.8 ABS engine?

best to use the engine's original gearbox, am I right in thinking that your generation of Passatt has the engine in the "normal" orientation for a fwd engine as its a platform shared with the gold but stretched.

should be quite a straightforward install if so, your gen did get the 2.8 and 2.9 VR 6 engines.

most vw (if not all) gear boxes and engines are interchangeable, so your existing gbox will fit on a v5. but the ratios will be all messed up.
if i were you id go for a vr6 engine (as said above) the v5 is a good engine but its as hard to install as a vr6 and you won't get as much power.... either a vr6 or a 2.0 16v would be my guess :-)

the passat uses the cable change gearbox and hydro clutch, so fitting a mk4 golf gearbox should be easy enough

4 banger box don't fit on the vr6 you'd need a vr6 box . But that's not a problem plenty of them about . Early ob1 engines have no imo which is a good thing have a look on you tube for the vr6 on throttle bodies

i know of a 97 18t still for sale at £300,150k but good and strong engine with no smoke (claimed)

I've recently discovered how good the 1.8T motor is, but the noise is no substitute for a VR6.

Used to have a VR6 with a ported and polished head, drilled air box and decat. Selling it was on my worst decisions ever
