Conversion

Hi doing a conversion in my caddy I have a aum engine going in 
And I need some help with intercooler and after reading the guide I have to change tensioner belt and does anyone have the part numbers of the things I need to get to change on the engine or suggestions or which parts woRk best
Gonna use vagtronics to sort out the wiring unless anyone has any other suggestions, 
Also down pipe ? Any suggestions I don't think qpeng do one anymore 
Thanks in advance, 
Muchly appreciated 

Just finishing AUM into a cabrio myself so if I can help at all let me know. This is the info for a cabby which I'm sure will be very similar to a caddy:
Intercooler - use a Merc Sprinter one or I got a new Ebay universal one for only £50-£60. Max size for me with the space between front frame & rad was 550mm wide x 230mm depth. 180mm depth will give a bit more room & work fine. ID is 63mm for hoses to match up easily. Inlet/outlet located at the top, not middle
Wiring loom - can recommend rubjonny myself
Downpipe - big tricky as noone advertises a K03/K03S version for sale anymore. Cheapest option I think is to buy a used mk4 golf decat downpipe & cut to suit. Or you'll need to get a K03 flange & get someone to make it. Go with 2.5” diameter pipe, not 3” unless you want your steering column boot to melt. Trackslag sell a K04 downpipe, means more power too, but then you'll need a more expensive custom remapped ecu with an Aum engine as far as I know & have to buy another turbo with all the lines (if you go K04 it'll probably be cheaper to start off with a BAM/APX/AMK engine as this will provide the K04 turbo, plus you can get a generic remapped & unlocked ecu on the cheap)

You have two threads going at the same time mate. Tensioner needed is 16v mk2 golf version & 8mm spacer required. Classic-Vw sells them in a kit including the engine/gearbox mounts

Someone and i cannot remember who advertises the downpipes on ebay. They are not advertised as downpipes but are in the small writing at the bottom of whatever is being advertised..Just says we can also supply the downpipes...

Cheers guys yeah I seem to lose the original thread couldn't find it, 

My aum is already at 180 brake? Is that correct as it was out of a mk4 turbo so think it has the k04 turbo already ? I might be wrong, it was more the part numbers for the tensioner I have sourced the belt 
And think now after reading this is have the right intercooler, change the rad, now onto mounts prob will just buy the ones from retrofication they seem quite reasonable. I'll check to see what turbo I have 
Thanks again guys 

Aum never had the K04 as standard, only the Audi codes at 210/225bhp I mentioned before: BAM/AMK/APX. I'll have a look for the tensioner code but there was only one type for the 16v mk2 golf

Yeah just found that out lol, it has got a kos3 so has bigger mapping possibilities,is that right ? I also got. 02j gearbox out of a diesel seat so that should sort out the lumpy 1st and second, and has 100 mm cups 
Getting back to the wiring vagtronics have said to remap and make sure all the gauges work they just want my new loom and they go in through the ignition, that includes the Rev counter and speedo with a diagnostic port temp sensor etc etc, does rubjohhny do it the same way ? 
I presume it's best to get the wiring sorted before the engine goes back in ? 
Thanks again, 

Also I have a pretty clean clutch on my Engine do is need to change that ? 
Cheers

Wiring best to sort out first before anything.
G60 flywheel & vr6 clutch much better (you can use the stock clutch & flywheel but you can't put a lot of power through it, only do this if you run out of money & plan to update it later)
You want all the selector cables & tower out of the 02j donor as well
Very cheap generic maps out there. K03s should get you 200-210bhp if everything is sound on a stock engine (K03 usually about 190-200bhp)

What I found out at an early age (15yrs) that when rebuilding a engine/tranny, even if you re running low on funds, wait for the monies as it is best to replace a clutch out of the car with new, rather than having to do it in 2-3 months.  (But I really got good at pulling engines/tranny's on MG's…..)

Thanks guys much appreciated, 

Is there w clutch cable on a o2j cable ? Cheers 

You can go hydraulic or cable. Hydraulic means running pipe from stock 02J gearbox slave cylinder to steering column, welding conversion bracket onto back of column, bolting master cylinder to bracket, run reservoir to master cylinder. Or cable means bolt converter & bracket on at gearbox end, swap out current clutch cable with a 1.1/1.3 cable that's 1457mm in length (this got from another thread as I went hydraulic)

Both methods will cost about the same roughly, cable easier to do as no fabricating clutch fluid pipe or welding involved. But it's your choice in the end as some prefer cable & some hydraulic. All brackets & parts you need are off the shelf

Cheers mate it's difficult knowing where to start, my old engine will be out this week fingers crossed so then the fun will start, did you sell your old engine? Mine is running perfectly so hopefully I'll get a decent return on that if I sell it whole 
Thanks again
