Caddy Engine Swop - Advice required

Post by michaelfalconer »

Hi Guys,
It’s been sometime since I last posted anything,
But today one of the rings on my 2010 caddy gave up the ghost. It’s been a while coming, thought there was still a bit more time.
So anyway I’ve been looking at either doing a whole rebuild of the lil 1.6 bsf (needs a new head either way) or just going and putting a 2.0 in there. From what I’ve managed to find on the interwebs is that even though this shares a lot of drivetrain parts with the Mk5, the engine isn’t one of them (unless someone can enlighten me). So apparently the 2.0 from the Mk4 will be basic plug and play, just need to set the computer box, but my question really is, which mk4 2.0 is the correct one that will fit without having to modify everything, as I don’t want to purchase the wrong one from the importers.

I did try the search function, but said my keywords weren’t good enough to search.

Any info would be appreciated

Thanks,
Mike

Hi Mike,

This is currently my plan however I'm going to wait till my 1.6 engine goes (doing 290k mileage). I have bought the 2.0 8v apk engine and have been working on it on a stand. I have replaced the headgasket(did a port & flow), water & oil pump but you dont need to do these on the import engines and you can just stick it in. I will be using all hanging parts from the caddy including the injection system( apk has fuel return pipe and the bsf doesn't)

Everything should fit but I will know for sure when I do the conversion, I'm going with uniQ for the fueling and tuning.
Let me know if you need any info on the a apk as I have purchased a repair manual.

Cheers

Thanks Ry@n.
I haven’t looked at this yet. There’s been too much going on elsewhere.
I did manage to find a 2.0 with a gearbox for R10k on the interwebs, but haven’t spoken to the guy selling as cash flow is a bit tight.
As soon as I find some time and cash I’ll keep this thread updated.

Hi Gents, please do share updates, also have a caddy with the 1.6 engine and would like to tow the race car around, and don't think the 1.6 would cut it.

Wonder how much of a mission the 1.8 T would be to get going in them with the standard ECU from the 1.8T.

The engine swops on the caddy2k forum are mind blowing with all factory ECUs.

It’s been a while, and I still haven’t got around to looking at this caddy. My PD was giving a bit of hell had to sort that out before I can spend anything on the caddy.

I will update as and when I get around to this, as I need this vehicle back on the road again.

That would make some nice power for a work van, but I doubt my customers will appreciate the extra fuel charges when I do call outs.

The Jetta Mk5 also had a 2.0l 8v model. My friend has one. It has decent torque and can get 5l/100km when he's in the mood to drive slowly.

If you can find a rear or side smash vehicle as a donor, I bet you could swap in the engine, harness and all the relevant electronics and it will work like stock.

The model VW should have built but didn't.

Morning guys, i have a caddy with 315 k on the clock and it's using oil, plus fouling no 1 plug.
I would like to convert to 20.l as i need more torque when towing.
Is the mk 4 2l best way to go and do i have to swop gearbox as well ?

Caddy panel Van or caddy pickup?

This info will help as it will radically change how a swap gets done.

This thread is directly related to the caddy panel Van.

Hi All

I have been living across the pond for a few years and cannot recover my old Paraclipse username.

Also interested in this conversion as my 2004 Caddy Panelvan (1600 BSF engine) is on 306000km and getting too expensive to run on #4 spark plug replacement and oil consumption.

Any advice from the old hands?
It seems a waste of money to properly and fully recon the 1.6 and still sit with no power!

The apk engine will work but If you can, get the bhy/bbx 2.0 8v it will make the install easier(off g5 and polo 9n, newer motors then apk) these also have the holes on the intake manifold for the map sensor and the fuel rail just like the bsf (no return line)
Everything will bolt on, you just have to cut, extend & join your camshaft sensor wires as these motors have them in the front, just behind the camshaft gear.
You will have to purchase golf 4 1.6 camshaft gear as the sequence (window spacing) is not the same as the 2.0 if not, you will get a camshaft sensor out of range error when you rev past 5k.

If you are on a tight budget or come across a good condition block / sub assembly then you can just stick it in with you 1.6 head etc. (easiest swap)

Lastly, you will have to get a Unichip installed and tuned for the additional fueling required, you can run it without the chip just don't drive it too hard and spin it near the redline. My ran fine for a few weeks and it's as if the ecu didn't even know there's a bigger capacity engine fitted.

For some reason these import 1.6 engines sell around 18k and the 2.0 is much cheaper and makes it an ideal engine swap.

Thank you SO much for your comprehensive reply, Ry@n!

Now I can start the exercise of finding and costing a complete import BHY/BBX motor vs a used sub assembly and rebuilding it before grafting my BSF parts onto it. Of course, the BSF head will need rebuilding first. It's good news that the BSF parts fit directly onto the 2.0 block.

I am not into making huge power but will the standard BSF heads valve sizes be OK to handle more airflow?
A larger diameter zorst will definitely be on the cards but fortunately I have a buddy who can do this at his shop.

I have done my fair share of 2.0 capacity from 1600/1800 blocks conversions in the past but unfortunately the BSF block cannot be tinkered with like that.

Having no experience of import motors and their quality leaves me reluctant to take the dive and possibly sit with a lemon.
Can other club/forum members please share their experience with import motors?
How would I even know if the "sub 100k" was really imported? It could be a local motor with high mileage and a skelm dealer...

An import BSF engine will cost me R16 500.00 in Jhb. Checking the bore and bearing condition, cambelt and tensioner etc is easy with a loose engine and replacing the full gasket set is also piss easy on the bench BUT this still leaves me with 102HP and 148Nm....

Going the 2.0 route will yield a bit more Vooma but might just re awaken the younger version of me - can the BHY/BBX motors be mildly modified without breaking the bank in future?
Police clearance is not such a mission so that shouldn't be a problem.

What is the ballpark cost of a Unichip and tuning in Gauteng?

Sorry about all the questions but this forum offers a wealth of information and can save me a shedload of money and frustration in keeping my Caddy going.

You can try Samco or Rojan's

What do you want out of it?


What is the ballpark cost of a Unichip and tuning in Gauteng? I'm not to sure but around R4500 - R6000 supplied, fitted and tuned or you can buy a 2nd hand unit from a reliable source (I paid R600 for a 2nd)

Sorry about all the questions but this forum offers a wealth of information and can save me a shedload of money and frustration in keeping my Caddy going. I'm always happy to pass on my knowledge / experience, we all share the same passion for the car community.
