I'm considering upgrading the Rocco's engine to something a little more powerful.
Now I've come up with four different choices:
1.) 1.8 8V from a Scirocco / Golf 2.) 2.0 8V from a MK3 Golf 3.) 2.0 16V from a Golf GTi 4.) 1.6 16V from a late shape Polo / Golf
Now, I want to keep things as quick and easy as possible so my preference is the 2.0 8V. However, if I'm going to all the trouble of taking the engine out, shall I spend a bit more time and fit something different?
There are a few complications / considerations though:
1.) It's my daily so it needs to be done in a week or so 2.) Has to be done as cheap as possible 3.) Has to cause as little a conflict with the wife as possible 4.) Can't be too outrageous because of insurance
I could get over the daily driver issue by buying a fully working doner car, take the Rocco off the road and strip it and get everything prep'd then do the transplant when everything is ready.
I'm sure some of you Golf / VW boys have done a similar conversion - so let me know your thoughts / suggestions.....and please stay away from the 1.8T 20V suggestions please - way too tempting.

Is your car FI or carb?
Guessing carb.....
I'd plum for a digifant 2.0 16v from a passat or golf MKIII.
pretty much bolt in, fabrication will include an exhaust manifold.... that's about it. (you may ger away with 2.0 manifold and a welded pipe, not sure!).
obv, the 2.0 16v mounts the same as a 1.6 or 1.8 8v, no worries there then.
The FI will be digifant, that runs on a seperate engine loom, which is wired to the fuse box, dead easy to get that sorted.
fuel pump suitibable for application may need to be sourced, as would a decent fuel line and possibly an FI tank, but don't quote me on that, digifant engines have a regulator on the fuel rail.... I think., so you may be OK.
A decent in line FI fuel filter will be required (you really don't want krud getting in the injectors).
that's all I can think of.... its a good conversion.
Of course you could always just run a 16v on carbs....

I'd approach a transplant on a daily driver with caution - things never go to plan (well, not with me they don't anyway!). If it's a straight bolt-in job then that makes things easier and quicker (in theory) but there's always those unforseen problems that slow the whole thing down. I don't know much about VWs, but a 2.0 16v sounds like the way forward. I'd look to get hold of a £150 smoker with a bit of T&T to blat around in whilst you do the work if it were me, that way the pressure's off and you can get the job done how you want it.

Had almost the same conversation with a friend an hour ago about an engine for his jetta, after I initialy suggesting the 1.8T 20v and him saying no, we decided the 2.0 16v was best for him. I'd still go with the 1.8T 20v though if it was me, but its not. Good luck with what ever you decide, but the idea to buy a 150 quid sh1tter isn't a bad one then you can spend your time doing it right.

Vote for a 2.0 16v from me 'cos that's the engine I put in my Mk2 Golf and it goes very well. I did a thread in 'Readers Rides' a while back with pics from the engine swap if you want to have a search for it. With mine it was a straight swap and I stuck with the 16v k-jet mechanical fuel injection already fitted to the car, depends what motor you have to start with though as to what your options are. I used a 6A engine from an Audi 80 Sport, easier to get hold of than the 9A Passat engine and basically the same thing.

The Scirocco currently runs the 1.6 8V engine that's in the MK1 Golf GTi, and it uses the Weber 32/24 DTML.
Does the Audi engine mate directly with the VW gearbox, or do you need an adapter plate?
Anyone know of the eqivilant Seat powered car to the Passat GT (I know how rare GT's are these days - however my fater-in-law sold his 2 years ago with 324K on the clock on the original engine.....it used to be an unmarked cop car during the mid 1990's in Leicester)?

Don't use the Mk3 2.0 8 valve, it's curse word and you'll probably find squeezing it under the bonnet a little bit of a mare. Size does matter in a scirocco engine bay, especially height and width of the engine/gearbox combo

The 1600 I presume is an EW? It aint no carbed GTI engine - they are 85 and lively, the EW is 75bhp and sluggish (well, mine felt it).
I would think the biggest decision is whether you want to swap to injection or not...
As mentioned, need pumps and lines and wiring. In theory you need the injection tank, but my injection scala has been running a carb tank for 18 months with no apparent ill effects.
But... I played with an 1800 carb and ended up with 125bhp@fly on RR, then had opportunity to purchase an injection Scala - drove it and bought it as felt far superior. A mate is looking at modding his '84 1600 GL and, having later bought an '84 GTI, came to conclusion that if going for sizeable power increase, may as well start with injection (he will be converting the GL to injection).
If you are on a budget, and more importantly keeping it simple: Tall block 2.0 8v eg Mk3 Golf, numersous Audi's, do fit in a Mk2 Rocco (struggle in a mk1), but require a few conversion parts at about 160 from TSR (but they are not the cheapest, and it should be possible to do it cheaper).
It's the head/cam that's a bit conservative on them I think - stick the carb head on the bottom end for an easier conversion... Not a huge jump in power, but should be a nice torquey engine, especially with a bit of head work and a decent cam (stick a GTI cam in if really on a budget). Weber seems to able to cope up to 125-130bhp.
The short block 2.0 is the 3A from '89-'91 Audi 80 (I think) and are becoming hard to come across in decent condition.
If converting to K-jet injection, 'KR' 1800 16v's (why not on the list?) are becoming easy to find very cheap - I got one £70 from Ebay, and then bought a whole partially stripped 16v Golf for £30! Of course you could run on twin sidedraughts, but that's getting a bit expensive?
You could still run k-jet with a 2 litre 16v by putting the passat/corrado/Audi short block with the KR head etc.
TBH I haven't looked at anything beyond sticking with K-jet - having spoken with a fw people, and reading the above, that could well have been an error...
