Bit of an update, fired it up today all is well so far, gonna have to finish it up so i can test drive it.
Any advice for the exhaust? Probably gonna leave the stock manifold but the cat is clogged up, since it's a 1.6 now, thinking about going to 55mm after the manifold and adding a resonator and a muffler but can't seem to find what size would fit. -
Old engine is out, a lot of oil leaked out of the inlet manifold, clean like new oil sign that there is pretty much no piston rings left, also a lot of aluminium filings up in the head, even some on the camshaft position sensor, probably that block is done for...
Any advice on "while i'm in there" repairs? -
So, some updates, seems like the AHW works perfectly well without the camshaft sensor, doesnt even throw a check engine light. Even if it does i can code out the error as long as it works fine. Everything else seems to be bolt on. Will put a new crank seal with the ring for the crank sensor and looks like the AFH should work with stock ecu and loom. We will see in the next few days how it goes.
-
So i've started doing the swap and can't really see a way when i remove the dizzy, and to use the AHW loom and ECU where does the camshaft sensor go?
Maybe use the output on the distributor, not sure if signal is the same? -
If i remove the dizzy and use the AHW coil pack, do the leads go the same way on the AFH as they are on the AHW?
-
Why? Just the internals are changed worked fine with the stock ecu in a polo coupe, it seemed to be adapting quite well by itself.
-
Okay this sounds really good. Will save me a lot of time.
Any thoughts on injectors? Use the ones from AHW, afh or better?
Engine has a 1.6 crank, bora conrods from the 105hp 1.6, and new pistons. With stock distributor, injectors and ECU it did 140-ish hp on the dyno. -
This sounds a lot better than using the older ECU and loom. Would save a lot of work.
I know the map sensor is the same, what about crank and camshaft position sensor i thought they are different.
Injectors seem similar enough, which would be better AFH or AHW one's? WOuld the ECU need a remap?
Thanks a lot you are giving me a lot of useful information :). -
From what little info i found on this conversion it says i have to use the AFH loom from the polo?
Is there a way to use the AHW loom and ECU? If that can be done would make it a bit easier and i'd be able to use the ABS.
Also the other thing is AFH using a distributor while the AHW has coil pack? I've seen maybe the same coil pack not sure fitted to an AFH but it was using aftermarket electronics so not sure about that.
Any pictures and info would be greatly appreciated. -
Well i will take the engine loom and ecu from the polo and use that but it would still need splicing to the existing loom in the car, cant seem to find the schematics for both cars .
-
Ok, so i got myself an AFH engine any pointers for connecting the loom? Mounting is quite straight forward.
Not sure if the lupo uses CANBUS for the tachometer i know the ABS wont work unless i get the one from the polo. -
Yes, but it's all apart so you change them and that adds to the cost, would be stupid not to. Re-using head bolts i don't know usually knowing my luck i wouldn't do it and as i said that weak alloy block will probably strip the threads anyway.
I have found a solutions, a AFH engine from a polo 6n1 fits to the original gearbox, and just need a new engine mount. Also a SOHC 1.6 from a polo 6n1 can be used with an AFH head and it gives pretty good results too. -
Don't need new bolts? New belts, coolant, oil, not to mention alloy block and the high change of stripping the threads, things add up.
-
So i found out some info, looks like the best way to go about it is older polo 6n1 block with rotating assembly + AFH head and pistons, seems to work quite well.
I'm in Bulgaria. -
Yes, have not taken them out tbh, not much point either no point trying to save this engine, would rather have an iron block and work from there.
Smokes a lot, and goes through the coolant and oil quite fast, so most likely a blown gasket as well.
So any ideas on the iron block or should i look for one from a gti which is pretty much impossible to find?
-
On mine? You mean to see if there is oil in the holes or if the spark plug it's self?
-
Goes through the coolant and oil quite as fast as it uses petrol :D. no idea on the km when a car enters my country it goes to the deffault 120k km.
Have not done a compression test, not much point tbh just by the noise you can tell it's on it's last legs.
Was thinking about the older 1.4 1.6 blocks from what i heard it's the same as the AFH 1.4 101 hp engine in the polo 6n1's but have not really found good evidence.
The car is my girlfriend's so thats why not much need for a really big engine, i was thinking about getting an old 1.8 liter mono from the passat/vento/toledo since they are pretty bulletproof but it's probably gonna be as much work as the 1.8t and thats why i'm looking for other easier solutions. -
Hello everyone, my AHW engine is pretty much dead i suspect worn piston rings/pistons probably valve seals and high chance that the block is for scrap, i know these are alloy so cant really be rebuilt, what are my options to put a cast iron block in it? Is it only from the lupo/polo gti which are really hard to find.
I know if the block is fine i can change pistons and seals and all the rest but it would come out costing more than a second hand 1.8t to put in there since i will be doind all the work myself.
Could i use an iron block from the older polo 6n1 that are SOHC and use only the block and crank/rotating assembly?
Have been thinking a lot from an entire engine swap to a better engine but the thing is everything apart from 1.8t is not really worth it because it's going to cost pretty much the same for worse results and 1.8t is a bit of an overkill for me.
Lupo 1.4 16V AHW problem.

I was going to get a new universal cat an original one would be too costly.
Idles fine, but on petrol there is a bit of hesitation at 3k rpm like there is not enough fuel, ordered new bosch AFH injectors these old one's probably need cleaning and filter changes who knows not much point refurbishing them when the new one's are cheap. And the garage put the AHW throttle body on in because it was brand new. So now when i change the injectors i will swap that out too and probably fit a new cold air intake and get rid of the tube that goes to the exhaust.
Otherwise on LPG runs fine so probably the injectors or the o2 sensor is crapped out.
Anyway here's a pic of it in the bay.
