The quest for capacity-Audi 2.0 8V conversion how's it done?

You know I'm not going to rise to it walt

Hi there kins! Im doing the same to my mk1! i hope you've got all the info you need but i'll list the extra parts you need!

-35mm core plug to block off the round breather hole
-A funny shaped plate to block off the second breather hole. Becareful because if youre doing the conversion to a mk1, then you need to make sure it can mount the warm up reg!
-A dizzy spacer ring. This is so you can use the dizzy on your mk1 because the 2.0 block uses bigger base dizzys.
-2.0 dizzy gear! You cant use the 1.8 dizzy gear cos its too small! So you need to knock out the roll pin and fit a 2.0 gear!

All the parts can be found or made up. I got the core plug off the place that balanced my 3A. The plate made by my local welders, just a shaped piece of metal cut around a new gasket i bought! I took the warm up reg mounting plate off a spare DX lump i had and bolted it to the plate! The spacer ring i got off TSR and the gear off an old one i had kicking around.

Now its as expensive as you want to make it! Gaskets and seals will need to be replaced. But will you change big ends? Crank shells? Piston rings? BIG MONEY!

I'll see if i can find a pic for you…

The 3 problems - breather plate 1 + 2, and the dizzy.

The two dizzys. The smaller one is the 1.8s one. It has a smaller base, smaller gear and has vacuum advance. You cant use the 2.0 dizzy because it doesnt have vaccuum advance as it would have been controlled by the ECU. If you fit a non-vacuum advance dizzy you'll have flat spots. Keep in mind if youre doing the conversion to a digipants mk2, then the ECU controls the dizzy advance.


Hows that?

Thanks for the info MrV Is the 17a a short block? What's the difference between a 17a and a 3a?  :dontknow:

I've never even heard of a 17a mate! The ones off the top of my head are 3A, ABK, 2E, ADY, AGG and AAD. The problem with the ABK/AAD route is that the oil filter housing is shaped towards the right which would hit the engine mount bracket. This is because the housing was designed for the longitudinal mounted Audi 80 engine.

(I dont know how to spell longitudinal :dontknow: )

Oh, and all the 2.0 lumps, apart from the 3A, are 16.5mm taller. This is ok in most cases but can cause problems with strut brace and exhaust manifold clearances.

Well I've taken a brave move and have won the auction for this……. hope I've made the right decission!

VW Mk1 Mk2 Golf GTi / Cabriolet 2.0 l 8v Engine

This engine was originally fitted to a '91 Audi Coupe.  This is a short stroke "short block" engine suitable for direct fitment to all Mk1 & Mk2 Golf GTi's. This engine was then fully rebuilt and fitted to a Mk1 Golf GTi Cabriolet but was fitted with a rebuilt "DX" Mk1 Golf GTi solid lifter head and wasalso fitted with the correct transverse alignment sump.  This was carried out around 5000 miles ago.  Rebuild details below:

Big End Bearings

Main Bearings

Thrust Washers

Oil Pump

Water Pump

Piston Rings

Valve Guides

Valve Stem Oil Seals

Injector Seals

All Belts

All Gaskets

Clutch

etc etc The engine was chemically cleaned before the rebuild process and all the valves/ pistons and crank were inspected for wear.  It comes complete with inlet manifold, throttlebody (Mk1), oil cooler, distributor, alternator (brackets also included) and clutch.








What do you think? :dontknow:  

Apparently it's a 17a so hope it's ok! I thought well its had some money spent on it and its been fitted to a golf so It'll make my life easier. All comments welcomed

'chemically cleaned '… i suspect he used 'GUNK'  :wink:

Looks good though, hope you don't get too many headaches fitting it

Looks good!! If its a 2.0 short block it'll be a 3A. It looks like it still has the breather pod on the block, if it was fitted to a mk1 then he may have used the breather on the block as well as the one on the rocker box. If its done 5k then it should be nicely run in. Oil cooling is a later style one which uses different hoses than our h/b MK1s, which was used on post '86 DXs.

I am also doing the 2ltr conversion. Going the 2e route and fitting it to my Mk2 GTI… its earlier, registered feb '84. Its great to read that other people are doing and have done this conversion. More people to ask when I get stuck

I really want to keep the breather setup on the block and connect it to the existing valve cover breather set up rather then using the blanking plate. My question is that I dont know where to put the warm up reg. Fuel lines seem flixible enough (although I dont know if it would affect its operation) and the wiring could be extended. Has anybody any ideas of a good place to put it, or have any pics of where they have relocated the WUR.

Some ideas would be appricated. Got most of the parts together, dizzy wheel, ring adapter etc.

Hi nanks welcome to the club!

Look at you no messing straight in the deep end with the big boys. I like your style.  :wink:

I'm still trying to sort out postage for my engine and waiting for him to get back to me with a price. As soon as I get it I can start work.

I did not realise there would be a problem locating the WUR  so if any one has any pics/description of how its done that would be ace.

Whats the crack with the oil cooling? What do I need to do to get it to fit or is it a no go? Any idea Mr V? The head I'm using is a TSR pack a head A head.  TSR HEAD

With regards to the breather on the block I will need to get my head round that when the engine arrives. What are the options there? Blank off the block breather (will this not raise the pressure and damage the engine?)

Mr V do you have any pics of the work you have done? If you do that would be a great help and would make things easy for me to understand. Cheers :wink:

Good luck with the conversion and let me know your progress. If you can post some pics that would be great.

Any questions get them posted on here. The more info we have to share the easier it will be

Thanks for the welcome  

I have been toying with the idea of the 2ltr conversion for some time, my car is sound but done 184K and strating to feel its age. Decided to go for a block that had been fully re-built for piece of mine. Paid ?400 but it is from some one with a good reputation. Will post some pics once I work how to do it. Also like you kins I have a TSR pack A head that I got for waht I thought was a good price secnd hand.

The breather… kind of thinking that it was put there for a purpose, but I have heard lots of people blankng it off and attaching the WUR to it. I'm open to alteratives but have not ruled that option out. So it would be good if people have any ideas. It would be interesting to know whether anybody kept the orginal cooler or had any issues with fitting.

Its good to share the knowledge and I will keep you posted on how I get on.

By blanking the breather on the block is that not going to increase the pressure in the block? Therefore increasing the risk of damage to seals & gaskets!? Also could it lose power due to the extra effort needed to turn over?

Help im confused and don't want to knacker my new engine :dontknow:

There is a 25!! page thread on the performance vw site about Mr. V's conversion - okay, the first four pages are he and I having a fight but it is probabl worth a read (just set some time aside)…

Its in the forum under engines.

Thanks Steve I am sure its a thoroughly interesting read!

I'll give it a read after work :wink:

P.S Who won the fight?

Cheers for the link steve… some good stuff…. bit of a long read though.

Had the oil through the dip stick… blocked valve cover filter, very messy!!

Did find out that the wur need to temp of the block to work. may try to rig up some bracket to relocate some where on the block. I'l see how it goes.

Thanks

I've just finished reading the link on PVWM took ages! But worth it. http://www.performancevwmag.com/forum/topic.asp?TOPIC_ID=26753&whichpage=1

Very useful.  :dance:

Too tired to write as I'm falling asleep at the keyboard but I will be back to discuss my current thoughts. :wink:

Howdy peeps! Welcome to the forum nanks, im a newbie too!

Dont worry about blocking off the breather on the 2.0 block because the breather on the 1.8 has the system on the rocker cover instead, so just use the 1.8 rocker cover, and use the 1.8 warm-up reg mounting plate on top of the fabricated block off plate. If its sound confusing, have a look on the previous page for my two photobucket links, ones of the dizzy problems and on the other one you'll see the two plates(one on top of the other, in the middle of the block) im bangin on about.

Thanks MrV… the breathing problem has been doing my head in… I'm almost ready to go on the conversion, got most of the bits and pieces I need, just trying to locate a engine stand so I can build up and an engine hoist.

Have been thinking of fabricating the blank off plate so I can mount the WUR plus some kind of baffled breather system to plum in to the valve cover breather… I would be interested to know if any body has done a baffle system to replace the gause/filter in the valve cover. Dims etc would be useful.

Thanks

The gause always silts up with carbon and blocks - causing symptoms which make you think your engine is dead.

If you speak to rally car suppliers you will be able to get "catch tanks" which you just plumb your breather pipe(s) into.  You can even get ones that return oil to the system…

I just run mine with no gause and a Pipercross oil breather filter on the end of the pipe.
