It’s very common, use 2ltr headgasket put 1.8 gti head onto 2.0 block use ether the 2.0 or 1.8 ancillaries, wang in a fast road cam for good measure and your away. lot of ppl also put 2.0 bottom ends on 16vs

With 020 (rodchange)box it fouls one of the webs on the block (02C clears it fine) you’ll soon see what I mean when offering the gearbox up to the engine, I rounded the edge off the transfer case and then took the rest of the metal out the offending web on the block, I have piccys somewhere, I will try & find them later

Please do Danny and post them on here, this is good info that is probably not available any where else.

btw Darren as you are running a carb and not injection you will need to run a distributer with a vacuum advance/retard which the 2.0 litre doesnt have, so I think you will have to run an 1800 dizzy which does have it, which means you have to change the intermediate shaft, dont worry there is one here you can have if you need it, or you could use the one (and the dizzy)from your spare GU code engine

iirc the 2.0 intermediate shaft dosen’t cause any issues, if using carb dizzy you fit the gear from the 2.0 dizzy to the 1800 dizzy you are using and then make a spacer ring, somtimes made out of 2.0 dizzy. haven’t had chance to find piccys yet may

Look at what I just picked up for £50 []

Not really a looker, is it?

Obviously this is what I’m here for:

Although it’s done 170k it still pulls very well and cleanly and will pull from 20mph in 4th – that’s the torque from the long-block, I guess.

Work cut out now then!

It’s a similar project. Mine should be running rear discs and a cable-change Passat Syncro/Golf Rallye ‘box, when it comes out of the garage. It is already running numerous other tweaks, too.

I was just cruising through the linked threads above and noticed that none of them really mentions wiring – after all, most 2l conversions are completed on Golf GTIs – no need to worry about that pesky wiring, when it’s all already done for you, now, is there?

As the MFA on the Passat says it’s running 35-37MPG average at the moment, I think it would be a pity to slap a carb on it. It’ll make the conversion more complex, but it should be easier to tweak and tune if it’s on injection. Now the question is really, leave the head on, or hunt out a crossflow head…… h’mmmmmm, decisions, decisions.
