Probably been asked time and time again but I have searched the forum and only seem to be able to find bits and pieces of advice, nothing conclusive really.
I have a Mk2 1.8 8v digifant and have just got my hands on a 2.0 8v engine from a mk3 (2e engine code) so wanted to know if anybody could provide me with a list or possible step-by-step guide as to the conversion?
The engine didn't come with the dizzy or the power steering pump unfortunately but I've read the power steering pump from my pb will bolt straight on (looks the same fittings). The main confusion I'm having is to specifics such as what dizzy to use. Seen a few posts saying use the 2e dizzy but then I have seen other posts about spacers and bigger gear to convert the PB dizzy?
Have pulled the engine to pieces (not fully yet, just split to sump/block/head) and the pistons don't look pitted so might get away with not having to do a full re-build however I will still be replacing the piston rings, belts, bolts/fastenings and gaskets (so any advice on which gaskets etc. would be great)
Thanks in advance

mine has a spacer but that came on the engine when i bought the donor car.im now rebuilding a new bottom end so im just taking parts from my engine and swaping them over.
on the front of the engine theres what looks like an oil breather or sumik its a black box with a pipe that comes off it and a part that plugs into the engine with a rubber seal on it.on mine that was removed and a cover plate was engineered to fit the hole and then a hole was drilled into the block and a thread was tapped to take a fixing to clamp it in place alot like the clamp that hold the dizzy????.you will also need a cover plate to cover where the other half of that breather box comes off which sits above the the oil filter housing.im sure you could probably buy these bits by now though but i wouldnt know where sorry :undecided:.id post some pics but moby wont connect to the pc.cos its really hard to explain.its sumik that will pop up and do your nut cos i dont think you can run it with out???the only person i would ask is rubjonny hes the guru! :grin:

what year is your mk2?
do u have the full loom for the 2.0 lump?
-
i never used the loom in mine as im running the 18 head and digi injection
-
Its a late 90 mk2 and I wasn't aware I would need the loom as I am also going to be mating my 1.8 pb head to the 2e bottom end.
So any more information on the oil breather at the front and the required dizzy?
Cheers

you dont need the loom dude just plug it straight in! the breatgher at the front of the engine you need the cover plate for the bit on the right and so ive heard a core plugg fits straight into the hole no probs.my dizzy has the spacer like i said dont know where you would get that part from
-
I need to cover it with a plate? I have read that a breather pipe/filter - possibly green filters/piperx etc. would be better as a plug would cause too much oil pressure build up?
Again, I these are only things that I've read so wanting to clear things up before I break anything :laugh:
Cheers

I believe TSR do the adaptor plates but you would have to ring them for a price. I also think they do that dizzy spacer.... :smiley:
-
my engine was mainly built by tsr they did all the head work and supplied gaskets etc its possibl;e that they supplied the blanking plates.i havent heard of any oil pressure build up befor and it certainly didnt matter with mine.if putting a breather on it helps and you do it let me know as i will change mine to suit.

ive just taken my 2.0 out same engine code and replaced with 1.8 mine was running on 1.8 loom its only a few wires and pretty much simple to wire from what ive seen, ive had to change my dizzy back to a 1.8 one so i guess you will need a new one?
can i ask why you decided to change to a 2.0? i was pretty disappointed with the power of my 2.0, i hope it runs a lot better with the 1.8 back in it
-
my 2ltr flies dude 136.5 bhp and 147.2 lb of touque whilst under fueling i reckon thats pretty dam good even though i did blow it up and am now3 in the middle of fitting anew one!lol
-
what have you done to get that power then? i presume it aint a valver?
-
I was just wanting that bit more power from the same 8v system and 2litre standard over a 1.8 bored out has to be more reliable.
The most power to be had is obviously from head work, which will be to follow when finances allow  :wink:
Basically the car is a nice base and I have already had my seats re-trimmed in black leather with white stitch and custom embroidered vw logo's on the fronts.  Currently sitting in my boot are new ball joints, new track rod ends, new wishbones with pressed in poly bushes, new solid front engine mount and new g60 rear mount all waiting to be fitted once then engine is done.  The engine itself is currently in my garage, stripped down and awaiting a re-build  :smiley:
Even though she's an everyday runner I want it to be a nice example.  The plan is to complete my interior and eventually fit a custom CarPC  :cool:

when i did this conversion on my last dub i couldnt find much info and had no end of problems due to using bit and pieces from different engine, i couldnt have my motor off road for more than 2 days, but if u got time i would use just them 2.0 bottom end, find a 2e dizzy as they fit into wiring(as long as its deffo didi ur old lump) if i was to do this again i would use
mk3 2e engine and dizzy
ur pb head including manifold and inlet manifold, and anything else from mk2 u can see
and ur mk 2gearbox
as for breather system at front of engine if u got complete enginge from mk3 use the mk3 rocker cover and plumb it all in that way or just put a piper x breather on the pipe coming from block(as i did no problems there)
as i used mk2 gearbox i used mk 2 uprated clutch( easy enough as u have the whole lot apart anyway)
u need a mk 3 cam belt and new cam belt tensioner
i used a metal head gasket which i believe to have been for the g60??someone else will tell u wot model car it was for but it was three layered metal gasket
while u got it apart and funds allowing i would replace oil pump too
as for putting it together it should all mate up nicely as mine did, just take ur time and double check everything
the 2l bottom end conversion wont give u much more speed but will improve tourque greatly
think thats it hope it helps

Just the info I needed but one other thing whilst I'm on... If I were to do a re-build of the engine where would I get the components from? - GSF website seem to do piston rings etc. for the mk2 but nothing listed on there for the mk3.
Thanks in advance
Ian
-
if u can i would buy internal engine parts from vw, some of the other companys are known for using non standard stuff, if it was me i would stick with genuine parts as best i could but its all each to there own
have u tried gpc in luton they sell genuine stuff??
rik
-
well the new lump is now in fitted with new valves,stem seals,steal head gasket from tsr and head bolts,new clutch,new cam belt ,tensioner and another mk3 2ltr bottom end pics to follow!
-
silky u do all the work ur self??
-
i did this time round.yesterday i got up at 8am fitted a new clutch,dragged the lump to my car fitted it and then built the head new followers etc all in one day on my own!!god im so impressed with myself!lol
im not a mechanic and have had help from a few friend naminly mr crean and the other would be rubjonny the guru!!!its all very easy once you start to understand it all.
the origonal 8v engine was replaced by me and a friend which came in a donor car along with a big brake conversion,full leathers and five stud hubs and speedline rims from an audi a4.then on saturday befor spring gti fest it let go which put a big hole in piston no1. so i got myself another mk3 2ltr bottom end from a friend and thats what ive just put in myself.just put my old head on it which had been ported,skimmed,polished and gas flowed with a big shrik cam which is where all the grunt comes from not to mention the stainless four branch i have just got.its cheaper to do it yourself than to pay somebody else!
-
yeah i did mine myself on the last motor too, it defo teaches u more abt the engine too
-
You did it in a day :shocked:
I've not even started stripping down the bottom end yet as England being England it rains more often than not and we've been clearing out the garage so we have some indoor space to work. My step-dad's a plumber and he's basically used the garage to store old boilers for spares so it's taken a few weekends for the trips to the local tip. :angry:
Hopefully get the garage finished today and crack on with stripping the bottom end. Thinking that it's going to be a full re-build with the exception of the pistons if the chambers aren't scored.
Whilst I'm in the learning mood, how does having the bottom end lightened and balanced affect the motor? Local grinders can do all the work apparently and it's only down the road, if it's going to increase performance I might aswell get it done whilst it's out. :smiley:

from what i can work out its only any good for sprinting not too clever for every day drive.
ive had a major set back with mine!the head had to come off again!! my own fault!some how a 10mm bolt found its ay into the head jamming an inlet valve causing it to bend now waiting for anew valve to trefit on wednesday and get her running again.
the advice i was giving was to just to the head work and have the fly lightend that will be enough to give you plenty of touque then next real step is a 16v with fat carbs! :grin:
-
Ahh no problem, I wont bother having it all lightened and balanced then, saves me a little extra cash :smiley:
Finally got the crank pulley off (what a biatch!) and the bottom end stripped, the cylinders look nice and clean and we've masked it all up and given her a splash of paint or two :cool:
Just have to wait until after the bank holiday now to get the parts for a re-build before we can start putting it all back together.
Cheers
