What engine code should I be looking for? :)
-
agu
-
What throttle body have you got now? Is it cable driven or wire (electronic)?
No point going through the effort of swapping from one to the other.
If your asking which engine is best throttle body and ancillaries aside then it depends, what sort of power are you aiming for? There's no one engine code that's best for every scenario.
-
erm bam lol
-
Auq if you can find one :afro:
-
I would say no to Bam or Auq being the ultimate 1.8t, it's a small port head and if one was to try build a quarter mile drag car they would have no use for the standard Bam internals, VVT, standard management or k04 and they would want a large port head instead.
As I said, no one engine code is absolutely superior in every scenario. I do not believe the above scenario is true of the OP, that's why I would suggest he just chooses the engine with the same type of throttle body as what his one is now.
-
and how can you compare a 1.6 to a 1.8t no matter what the throttle theres no comparison
-
Electronic or cable. An average person doing the conversion on their drive does not want to buy a 1.8t to find it is drive by wire (electronic) when their car originally came with cable operated throttle body. It's not a case of just swapping over the throttle bodies.
-
It has electronic as I found out when I asked aRd to see if I could have cruise in. Not sure at what power really. 300 would be awesome, just want more power If I'm honest. Something I can work on and build up to be a monster
-
BAM AMK both both forge bottom ends and cranks big injectors but have VVT.. Or if on a budget.. And my prefferd pne..AGU they have forge bottom end and bigger valves smaller turbo than the other two but can soon be changed
-
So you already have a golf 1.8t? What engine is it? You could go down the simple way which I have on my daily and it's awesome..
K04-001 turbo (straight fit ment)
Saab injectors
3" turbo back exhaust
Front mount
007 diverter
3" MAF
3" TIP
Cc tuning custom map
Goes really well.. I've also got a meth injection kit to fit so should be even better after that

Whats yours running at??
-
No I have a 1.6 dude, looking to convert
-
dont go bam to expensive get a agu for 200-300 then buy a ko4 turbo for alot less than a bam

No I have a 1.6 dude, looking to convert
as said mate best startin with a turbo save you a lot of f**kin about :smiley:

All the 1.8t have the same size valves although the exhaust valves on the Bam are made of inferior material. It's only the inlet ports and valve throats which are enlarged on the agu.
For 300bhp you may be better off on an aum, it will give a better power band and torque than on the agu, what's more you won't be near the limit of flow capability for the small port head don't worry. Although a few my mates run over 300bhp and similar torque on a standard aum/auq you may like other 1.8t owners just want to drop in forged rods and sleep easy. As you already have an electronic throttle body you want to stick to a 1.8t with an electronic throttle body (me7.5 management) it's a more straight forward conversion and much nicer to map than the me3 counterpart
You should go for Bam or Aum but you do pay a premium for the Bam, Bam pistons are slightly lower compression so will be nice if your sticking to small turbo for the 300bhp and will make the mappers life that much easier but generally speaking if all you want is 300 bhp you will have enough headroom on the higher compression Aum pistons. Naturally the higher compression pistons of the aum are nice if you decide to go for a slightly larger turbo, you will find that the higher compression pistons reduce transient lag.

What bhp isyours running at with mods?? Looking fit hybrid turbo to mine be bit more aggressive tho than 001 turbo, i'm running meth inj spot on upgrade.

I need to get it on some difrent rollers.. The chassis kept touching the floor when lowering it down on the rollers.. Pluss by the time he got the Saab Injectors mapped in he said I was running really hot..
But.. It got 210bhp and 249 lbsft holds the torque through most of the revs.. Pulls really well quicker than my mates scoob and mate mk1 focus rs and his is running 240
Really impressed with it.. Was gutted about the figures but when I drove it it soon changed.. Feels awesome, like I said I've still got the meth kit to fit yet also :)

Buy a car with 300bhp or a MK4 with a 1.8T
A few years ago, a conversion would be a cheap way of doing things but you can pick up MK4's for so little these days its not worth it.
Add to the fact you'll need literally EVERYTHING from the front end of the 1.8T from driveshafts, to hubs, anti-roll bar, coolant pipes etc etc
My mate Dai converted his 2.0 and needed all the above plus more. He was lucky in that he bought a donor vehicle, was handy with a spanner or two, and had a couple of people to help out :wink: He made a few quid by breaking the donor vehicle.
Converting a 1.6 will be just as hard, if not harder and is not worth the hassle IMO

I agree with the above, it is better to buy a 20vt golf to begin with than to convert unless you plan to rebuild the engine. For one, there are many advertised 'engine conversion packages' for sale now and not just on eBay, theres no guarantee the engine is as advertised, if one was to install an engine that was advertised as having 48000 miles only to find it shows 110000 miles on the clock after all that work of doing the conversion there's few who would take it all back out again, strap it to a pallet and arrange for pallet line to collect it. This is a very real scenario and it has actually happened to myself before but the engine was intended for rebuild from the very start so wasnt so much an issue.
Although no one is saying not to do the conversion we are advising against it or to approach with caution and extra budget because of all the headache and possible problems. There are a whole host of other things that you should consider not least the possibility of getting a non runner, an engine with mechanical problems, work valve stem seals? Piston oil or compression rings, bearing issues, seized tappets or just dead, all entirely possible when you consider the 20vt engine from its infancy is now well over 10 years old! Buying a 20vt golf means you can test drive it for more than just a few minutes to make sure everything is good. Today you can pick up a 20vt golf for not much, so you really have to ask yourself if it's really worth it.

There is a lot on this thread to consider, thanks a lot guys!

"gti-boz" Should be way past that once set up right be looking 240ish plus anther 15-20 bhp with meth. Mine was 218 with meth off 231bhp with meth on have interior switch to turn on/off. Want snow meth digi controller to control system just pretty expensive but it will come

Yer t is strange as my mate has similar figures on his mk4 and he hasn't done half the work I have.. Leaves his for dust aswell that's why I was confused with the figures and performance
