1.8 20v turbo motors

[Demon Tweaked]

So tell me, is this a good motor for a citi? Maintenance? Part Availability? In modified form does it do well with more power than it currently makes?

Or would a 2L 16 turbo setup be a better option with regards to the same questions above?

It would be for a daily drive. power expectations 150kw +

Thanks

1.8 20V motors are strong and reliable. In stock form it will be very nice in a Citi
Same motor as the Mk4 and Polo GTI's.
Parts shouldn't be a problem and if looks after it will last you a long time.

And with some tweaks can make huge power.
How does over 600Hp sound?

Awesome bro. I was reading up on some threads here about these motors and i always had "2.0" in my mind. I see that 1.8T will do the job as well. If i go this route i wouldn't want itto be in "stock" form so will it still be a good idea?

300hp on stock internals pretty safely.. i really dig this motor.

for swapping into a citi i believe the older motor from the audi is thene you want. cant seem to remember, i think coz it has an external waterpump like the stock citi engine.

Awesome, guess its a done deal. I could have got that motor from my Cuz who wrote his S3 off but the insurance wouldn't let me buy/have it.

im loving mine , for both daily driver & race car, i have the stock 1.8T with bigger turbo & bigger injectors & i i make just over 300hp @ 1.3bar boost

I recently bought an Audi A3 1.8T & i am very impressed with this motor.

Im sure this motor in a citi would be a whole lot of fun.

howsit guys ,,,if i may add my 2c ,,,
i have a 20v turbo in my velociti road and race car as well..
using a AGU head on a 9A block ,,single coil + distributor...lol
makes 403bhp at 1.5 bar wheelspinning without the nos ,,quiet frankly i dont think i need the nos anymore ,,

u wont go wrong ,,,if its done right.

yes that is correct it has a external water pump which allows you to use your citi engine mounts, The newer one eg from s3, a3, gti G4 ect have a internal pump and will need a new engine mount made up but isn't impossibe.

I will have to search through my notes to see which block code the external water pump motor is!

As long as it maintained and looked after it will look after you as in any motor.
your gearbox and flywheel fits straight to this motor, is prefered if you fit a full cable shift box tho.

Mine should be up and running by end of the year.




Sweet sweet.

The main thing here is DO IT RIGHT 1ST TIME !!!!

Why did you go AGU Head on 9A block?

I thought your car was a 2.0!!

what does a motor like this cost?

[panic-mechanic]

The engine code for the external pump motor is APU surprisingly.

I initially had the 20v head on my standard afx (velociti 1.6i) block...we did that coz most of the people we spoke to told us we couldnt ...hahaha
farkers who think they know it all !!!!!! (btw- 20v head + afx block + turbo + nos = 297kw) on manny's dyno..

when i replaced the 9a block in my bakkie with a long block, i decided to change the car and make it 2.0 lt since i had a spare block.

not a bad figure Thanks man what turbo are you using?

[Stu]

my mac that is building up my polo did this mod before in a mk1 and it made 416Hp on the wheels on stock internals no problem but they run just over 300hp on the wheels for everyday drive

Insane

I would be happy with 150Kw + everyday. When i grow up i can start making more power

its been changed so many times ,,i dont even know what to call it anymore..lol
.63 exh housing + .50 compr. housing wid a 84mm wheel.
works pretty well ,imho.

what does a motor like this cost?

Last I saw one , was around 18K if I am not mistaken.

RoadHawg just a quick question? I'm also doing some research on a 1.8T 20v conversion for my mk3 GTi and I just wanted to know in your opinion which engine (Golf4/Audi) will suit the mk3? I have been following the thread of Bob with his mk3 Jetta. Will it be better to fit the golf 4 gearbox too or put something together like Bob did? ABF box + vr6 flywheel etc etc?

Ideally I would like to have my A/C to remain too...Any ideas?

I suppose its money well i spent..i hope

The motor as it comes out of the Passat /audi (APU) code has a number of issues to fit.
1) the exhaust manifold will place the turbo right on the rear engine mounting. (so you have to dumpt hte turbo and manifold and get the mk4 golf bits)
2) The intake manifold is different and unless you do some serious contortions with your plumbing it is an issue for space.
3) you cannot use the aircon/ps/belt setup as it comes on that engine and then you have to fit the mk3 bits back. Thta becomes a whole mission of it's own with trying to make drive belts work becuase the main pulley is mis aligned.
4) the oil extension housing is wrong and it tilts the filter towards the rear of the engine - on the mk3 that ends up smack on top of the front engine mounting. The oil extention housing from the mk3 fits but then you have to get a fitting to reconnect the oil supply line to the turbo as the stuff off that motor does not work.

So in my opinion - the motor out of the golf4 will be better - the only thing I don't know is if it still has the same rear engine mounting pick-up holes in the block because they are not used in the mk4 anymore.
I can't help you with your gearbox questions. I don't go to the trouble of changing rodshift boxes out to hydraulic/cable boxes and the ensuing amount of work it entails. (fitting hydraulic cylinders, manufacturing mountings swopping gear mechanisms etc.etc.) In my opinion if I want a car with cable shift and hydraulic clutch I'll buy it.

PS - engines like that go for around R12k usually minus turbo.

ya. dont ask me. ask panic hehe.

your opinion about dropping this in a citi? Why is it people tell me i have to have a cable shift box? I currently have a FFZ box

[panic-mechanic]

In a citi the APU engine is easier because it doesn't have the in-block waterpump and still has the nounting point for the right side engine mount. It's easier from that point of view because you don't have to manufacture a mounting that comes around the motor - you just bolt the normal citi engine munting to the block. Yes you lose the cover but it's not a problem - you could probably hack it to pieces and re-use it. I think I had to drop the idler tensioner pulley and the hydrualic tensioner and use a normal 16v Tensioner and belt on the caddy becuase they interfered with the mounting. It's not a problem though.
Then you could probably use the manifold and turbo as it is in the passat if it comes with it. I used golf 4 manifold and turbo
You will most definately have to change the intake manifold to the golf type as it will foul on the radiator on the mk1.

There is no MUST use the cable gearbox. I ran 250kw on the wheels on my mk2 using a normal 020 gearbox and I only ever stripped 5th gear once - also due to stupidity playing with a guy on the highway going out of boost and then putting foot and back into boost at 220km/h - repeat 5 times and it took the teeth off the gear. You can make up clutches to hold huge HP and if you have bolts in the diff the box will stay together if you don't drive like a ****. Don't drop the clutch on every opportunity and feed the throttle instead of slamming your foot flat, choose the right gears when you drive so the engine can rev instead of dragging it into boost from nowhere so it spikes and the box will be fine. If you make less than 180 kw on the wheels you can even use a stock clutch.

I had one of these in my caddy for a couple of years in basically stock form - it used to make 153 hp and 235 nm on KAR's dyno. I towed my race car on a double axle trailer everywhere and I used a stock CTI clutch . It never gave me one day's worth of trouble and I never broke the box. That was probably one of the most pleasant little run arounds I have owned and if it wasn't that I'm very uncomfortable in a caddy I might have kept it. It could also haul ass a bit if you wanted to....
Gave me 12 km a litre in everyday driving form and 10 km/l when towing the race car around.
