'76 MK1 1.8T AGU Conversion

[dubsquad]

There's a couple guys on here that know about it but anyway here it is...



Soon this will be out...


and replaced with this


It will be running Qpeng management with K04-001 turbo bolted to Golfloon's infamous TDI gearbox. So far i got most of the parts needed except the turbo,engine management and 8v clutch.

The turbo should arrive in the next couple of days. Spoke with Ben from Qpeng and he's picking the engine harness up tomorrow so will probably take a week or so to modify it and send everything back and the clutch i'll have to order from GAP.

I'm happy to hear from guys that have done this conversion and the problems they encountered.

So watch this space...

Nice dude.

Looks like you've got a clean, straight & rust free base to work with too.


Look forward to updates.

If your getting a clutch, I'd suggest getting an upgraded one over a stock replacement 100%.

Also. the only difficulty will be the AGU engine mount & gearbox mounts, but if you good at welding/fabricating, you'll have no drama's.

I suggest using a mk1 diesel engine mount as a bases for your custom engine side mount as these are a much larger & stiffer rubber mount than the normal stock petrol version.

Would only recommend genuine VW mounts too. I've tried all sorts of different brand mounts & most of them sag within a few weeks.

Another tip when using a AGU. You'll need to remove the Hydro cambelt tensioner & replace it with a 16V manual tensioner & a standard 16V stud & you'll also need a spacer fitted behind the tensioner to space out & keep the cambelt alignment spot on. Use a stock AGU cambelt.



If your not sure about my info, I actually mounted an AGU 20vt into my gti in 2000/01, but ran out of funds to finish it off, as I built a tough V8 ute instead. hahaha. Still don't regret either.


My only other suggestion would to be trawl through "vortex" or "clubgti" about the ins/outs, whats/wheres of this conversion. There is some very nice installs out there!!!

Other than that. Good luck with it all.

Thanks mate, i know i need all the luck i can get. I've already got the driver's side engine mount with heavy duty bush from a dude in the UK that makes them but will change all the bushes to prothane ones soon.


You need a 8-10mm spacer for the timing belt to align with the rest of the pulleys and 16v tensioner.

Clutch wise i'll go for the heavy duty sachs clutch as other aftermarket ones arent really for daily driving.

I've probably been through all the built threads on Vortex,the mk1 owners club and on here. Will scroll through "clubgti" tonight.

Thanks

I'll be watching this with great interest

Diddo!

So much awesomeness...

I'm really keen to learn more about these conversions.

Kudos and best of luck!

Run a factory ecu with something like Eurodyne Maestro map, better than any aftermarket ecu.
We run a 1.8T with a GT3071 turbo, 630cc injectors and all on factory computer, IMMO removed.
Runs as smooth as silk, retains all VAG-COM diagnostics and we are able to self adjust the tune if required.

Reason i going with the Qpeng management is for a straight forward installation, only the necessary wiring in the engine bay, its fully programmable and if i have any problems i can just give Ben a call or someone else on here thats using it. I wouldnt know where start when looking at factory ECU and all its wiring. I'm buying the full setup with K04 map and CAN interface for self tuning as well. My plan is to learn the software before i go bigger.

info...

Prolly one of the most informative web pages around for info is kirsten's 1.8T into a Mk 1 Scirocco site

All Things Scirocco and Turn Signals for the Mk 1

and Andy's scirocco builds...

VWvortex Forums: The official 20v (to start with and then FSi with 4wd) build thread aka "Brits Gone Wild!!"

and the other car...

VWvortex Forums: The polov8 3 day 1.8t mega-swap (aka skinned knuckle fest )

Scirocco is identical to the MK 1 golf except the rocco has a slightly lower hood line.
Both of these guy's are major attention to detail maniacs, but very thorough in there builds, plus there both friends of mine.

Any links on who did the immobiliser defeat bud ??

With your clutch, we run a lightened t4 4cyl flywheel and t4 5cyl clutch kit.This will be compatable with a dsl gearbox and the price is kept low.Been running this set up in the caddy since 03 with no problems.

[dubsquad]

Thanks Grant, some great info there. I'll be running a Eurospec lightened flywheel with 16v pressure plate and heavy duty Sachs 8v (24 spline)clutch.

Update: Did a bit of maintenance - Removed valve cover to change leaky gasket.


New waterpump, thermostat and engine mount fitted.


Cleaned and painted valve cover and inlet manifold



All back to together with S3 injectors.


Also got a 9mm spacer made yesterday to space the tensioner out, only thing now is to get a bolt for it. Will the standard 8v tensioner bolt fit?

Cheers

Nice look dude!! Love the black finish


The standard tensioner stud should fit. I know mine did.


Just a note on the clutch. Depending on how much power you may/may not make, I'd be suspect on the HD clutch.

I ran a Sachs Heavy Clutch myself up until recently & it exploded the clutch disc from the power of a mild 8V turbo setup.

Thats not with clutch dumps or race starts or anything. Justaccelerating & feeding the power on.

Will have to look into it, maybe go for the bigger 228mm setups at a later stage. I would like to stay with a 020 gearbox as it's a straight swap. According to the Qpeng site with K03s you'll be looking at 230hp. Hopefully i'll get around the same figure.

this is great! keep it up

Yer man, i used a ACT clutch and its great, my 020 is OK touch wood and i just laid down 249 hp, nice paint man what did you use?

I think if you want hard starts though you need an 02a with pelo and 020 would die in the ass with a lsd IMO.

230hp from the Peng boys is a tad overstated imo, i mean with a ok tune at 15psi mine pulled 249hp and thats with a gt28rs which is **** loads bigger than a k03s, still mine had a massive boost leak so who know i would be keen to see yours done tho mate its looks fing great.
