i own a polo 6n with a N/A diesel engine code AEF, i would just like to know if it can be turbo'd if so what bits will i need, also what will i need to change (i.e. piston's comprasion ratio?) and how much power output am i likely to recive.
-
you could just slap a turbo on and increase fueling a little bit, but more smoke off boost. N/A's aren't built to take the heat like TD's do, although there is some speculation that at a certain point N/A heads were the same as TD heads.
-
Im beginning to think that the only reason people say this is because they have never tried turboing a N/A 1.5
Im told with the larger exhaust downpipe you will not need oil quirters or even the hydro lifter.......
I know people on this board that have both a turboed N/a 1.5 and a reg 1.6td
who knows...In time Im going to have alot more experiences with this and can up-date for those who wonder like me...It would be nice to know forsure about the heads being the same...???

I got a Polo 6N to myself. It has oil squirters and the cylinderhead and pistons are identical to the AAZ stuff.
The main problem is the gearbox (085) and the clutch. Than the second problem. Can't mount a 02A gearbox easily because the engine is leaning forward intstead of backwards as in all the other diesels.
Than the Lucas IP. Get rid of it and place a AAZ pump. (better performance and better fuel consumption without the turbo mounted) You have to cut out a little plastic from the lock plate where the headlights are mounted in. For clearance of the LDA.
I stil have to dril the hole in the back of the engine for the oil return hose. The other things are plug and play. The oil feedline can be mounted directly to the oil filter adapter.
Injectors are the same replacement as on the 1.9D. I switched them over for DNO-SD261 with dual stage 1.9TD bodies.
Intake manifold is ok for now. Because I'm going to place a T2 from a AHU TDI it fits.
As soon as the new engine and transmission supports are ready than I'm going to put the M-TDI wit 02A in the car. (needs time and money :cry: )

I have a AEF in my Skoda Pickup, and I know a few Skodas that are running with turbo. One that has over 200hp :shock: so yes, it is possible to put a turbo on a AEF.
I think (not sure) that you will have to change the mounting bracket for the Bosch IP.
Just get the exhaust manifold, turbo and IP from a Golf GTD or a AAZ Passat..
That´s on the TO-DO list for me too, but first I´m going to give my truck an inch or 2 of lift...
-
1.9 NA pistons and rods are different than 1.9TD. But no worries, those will be fine too.
-
I've checked the internals of my AEF 1.9D and there where oil squirters and according to the VAG part software whe pistons and rods are the same.
This engine is not the same as the 1X engine in the Golf / Jetta Mk3.
-
Yes, every 1,9 diesel has squirters. Yes, AEF has differents from 1Y etc 1,9NA´s. But it has same connecting rods and pistons as other 1,9 NA´s, which are different than 1,9TD ones. Rods are 6mm longer, pistons are same 6mm shorter and piston pin is 24mm.
At least this is what etka and mahle catalogue (http://www.motorenteile.mahle.com/eLIZA/app/welcome?locale=en) says.
-
Aha ok, thanks for the correction.
I think it will last with a turbo and mild boost until I finish up the M-TDI with 02A tranny.

i found a cable operating O2A gearbox out of the ibiza's so no need to mess about with hydralics, when you've got the mounts made let me know as i might need them from you to copy or pay you to make me a set, thanks for help
sorry about this but all i have to get is a
Fuel Pump
Turbo and Manifold out of ???( what engine/ Car)
what else as i already have bought a vento with a 1Z engine is this anygood for any parts??? or should i let it go to the scrap

There's a turbo converted skoda 1,9d (same engine as in the Polo 6N). He's running up to 2,2 bar! And the engine is totally stock.
Best 1/4 mile: 13,96 @ 162 km/h.
Turbo: Switzer S1BG
Modified pump ofcourse. http://www.skodapg.se

What specs do you need to know? There's plenty of info on the page so it would be nice to know what you want to know so that I can translate it for you.
-
You can also use one of these to change the 6N it to 02A transmission:

thanks for help all of it would be appreciated if you could as i can't seem to get to the spec list as well as the how to do bit(sorry for being silly) thanks again

I stil have to dril the hole in the back of the engine for the oil return hose. The other things are plug and play. The oil feedline can be mounted directly to the oil filter adapter.
Intake manifold is ok for now. Because I'm going to place a T2 from a AHU TDI it fits.
Is the block on a AEF the same as an AAZ? Maybe the oil return that is used on the AAZ is there, hidden under a plug?
Do you know if IZ and AHU have the same style exhaust manifold? I´d like to have the turbo underneath for clearence under the bonnet..
I´ve just started planning this job, havent decided on what turbo/manifold to use yet.
-
The block is the same with the oil return bung? and all but the hole isn´t drilled/tapped.
And the AAZ misses a mount for the AEF style water pump. But you can easily make one. But an AAZ water pump on AEF is no problem.
-
Tack!
It would have been too easy if the oil return was drilled/tapped :lol:
Now I need to find out what manifolds to use.
-
Indeed the oil return hole has to be drilled and tapped. Not a problem but it's cleaner if you remove the oilpan and put something over the crankshaft and other components.
Even the 1.9TDI is not a problem to mount in the 6N but you need to find a solution for the gearbox. You realy don't want to keep the very weak 085 transmission.
-
Hi i have a t25 van with a 1.9 n/a aef polo engine fitted in it. The engine has a lucas diesel pump. is it possible to fit a Bosch diesel pump instead.
If so what pump will fit? ie AAZ? etc.
Thanks
Dridgy

I'm almost finished with my conversion. For now I installed it with the "weak" 085-gearbox and a special clutch made for this gearbox (170mm)
I got some pictures made with my telephone as soon as I got proper pictures I will post them here.
