can i fit a turbo to my 1.6?
anyone done it?
-
Be more grief than its worth. Youd be better doing a 1.8t conversion or better still selling yours and just buying one

no point.
-
The price you can pick a 1.8t gti up for now really not worth the effort
Probs be cheaper to ensure aswell

And faster :rolleyes:
-
it was just a thought
what petrol engine code should i be looking for then?
-
what ever you want agu arz aum auq are erm all of them :grin: apart from the tt's etc
-
AGU
doesn't have crappy sensors and secondary air intake.
Has a proper gear linkage setup unlike ARZ
Large port head
Forged Rods
only downside is turbo can only put out about 190bhp
forged rods?? if so why do you have to replace them when running 300+lbft
think you mean forged crank :wink:
-
ive heard this too about forged rods? maybe there forge just not super strong? haha i duno :)
-
No 1.8t came with forged rods or pistons... what you have heard is incorrect.
The majority of internal water pump 1.8t have forged crankshaft if that's what you mean...
A lot of misinformed things have been mentioned but the important thing is if an engine conversion is to be done it is best to start with the throttle body - is your car drive by wire or cable? But is out of the scope of this thread.
I agree with the sentiments of other members; it's cheaper and much less headache to just buy a 1.8t gti and stick a few bolt on mods then map it as opposed to paying someone to source and do the engine conversion on your behalf.

ah ok... but is the agu internals stronger than aum auq and same as bam? or they all identical?
o yea and agu is drive by cable... much begter imo :P
think there all the same except i dont think the aum, auq etc run a forged crank.
-
Aum and auq run a forged crankshaft, yes agu has slightly stronger standard rods compared to aum. Which is all pointless given that they all will more or less handle 300 ft-lb of torque for arguement sake, but if you wanted more on either engine you would ideally upgrade the rods anyway...
The cable throttle is a benefit but so too is the me7 ecu fitted on later cars when it comes to mapping.
Bam also has forged crankshaft but the piston is different from agu or aum or auq for that matter, bam pistons are lower in compression although it retains the same stroke and bore size.
As I had said before, whenever I do an engine conversion I always source the same type of throttle engine as what the car had originally. So if a car came with drive by wire, then fit an aum, auq, bam, if it came with drive by cable then stick to an agu, I would not bother changing between the two and chances are most people would not be willing to pay me extra to change between it anyway...

iv just done a aum conversion to my 1999 mk4 golf from a 1.6 and tbh id never do another one more hassle than its worth only reason i done it was because i got the car so cheap id deffo just go out and buy one next time
-
You can pick a running 1.8t a3 or golf up so cheap now, my mate just bought a running 02 reg golf 1.8t for £900 with the turbo seal going a little. Bough a k03s for well under £200 and fitted it. All running fine now. It's simply not worth it anymore. We have to remember the mk4 is over 10 years old now.
-
AGU has bigger wrist/gudgeon pins, that is all :wink:
-
ring your insurance company first and tell them you are converting to a 1.8T engine and see the price :sick:
then get a quote on a car that is a 1.8T :smiley:
modifying and engine transplants especially up your insurance
-
AGU had 20mm pins, which is a good number over the aum's 19mm. Popular thing is to use the 2.0TFSI forged crank, then you end up with a stroker setup with a 2.0t 20v engine. There's loads you can do with the 1.8T engines depending what power you want, as exhuast valves give up around 350bhp, so you may as well upgrade the entire valvetrain if you aim to go beyond that especially if you want to raise the limter. Then with all that power there's issues with the driveshafts, then gearbox at high end power... it's all fun and games. Then you have rod's and people up the pistons as well... but I won't bore you.
Best bet is just go and get a 1.8t golf to begin with than nonse around with a conversion especially with the price of these now.

cheers for the replies guys
rockmonkey what have you done to that 1.6 in ur pic? looks very interesting :smiley:
-
Thats a 1.8T

Removed the 1.6 and put in a 1.8t, stripped the 1.8t down and completely rebuilt it with forged internals and all new components, i.e new tappets, oil pump and pickup etc etc. ported, port matched and valve work. Being run in on stage 2 at the moment.
-
My engine is to be a test bed for a hybrid setup running external wastegate and later in the year it will likely be goin twin scroll
-
i was excited tinking dere was a 1.6 turbo golf in here :laugh: wats external wastefgate?

Internal sits on the turbo, external will be sit on manifold etc, basically screamer pipe is an external wastegate example.

I think its an AGU

Yes it is indeed an aum.

why did you choose aum over the others?
-
Because originally it had an AZD which was electronic throttle body, as I didn't want to bother with the hassle of changing. As I had planned to rebuild the engine it mattered little which engine I chose and because the aum is cheaper than a bam this was naturally my choice.
There are underlying technical premises for my choice too but I shall spare you the dreary talk :grin:
-
ah i see
any tips for my AZD?

Remove it and fit a 1.8T? :huh:

Tuning a naturally aspirated engine - more specifically a small displacement naturally aspirated engine is quite a technical exercise. There are many unfamiliar concepts that form the basis of this type of tuning which one needs to understand if they are to extract any significant gains beyond bolt on modifications.
Assuming you are not an engine builder, it would be better value to swap for a 1.8t whether this be an engine conversion or selling up: the latter being a lot less problematic with insurance and less effort. It's pretty surprising how cheap the 1.8t variants are now.
