Right.... Before I wade into this conversion

[drivebycar]

Its been drained. how do you go about priming a fuel pump then? 

Also, how do you swap the gearbox over from the old block to the new one?

oil pump
you gotta take the sump off and then the oil pump, clean out the oil pickup then submerge the pickup in oil (I normally half fill the sump with fresh oil to do this) then pour oil in the top of the pump and spin the pump shaft till it flows out the top of the pump.  quickly bolt the pump back on then the sump with the oil still in it!

do this with the engine in place as trying to do it while the engine is hanging off a crane will result in oil everywhere, as it wont be hanging straight.  Learnt that the hard way 

Course you could try filling it with oil and turning it over on the starter motor for up to a minute, you never know it might be ok.  If oil light doesnt go out sump off time!

Gearbox you simply turn engine over to TDC, bolt on a new clutch, fit yopur old flywheel so TDC punch mark is at the top, bolt on box, job done.

I'd recommend you replace the input shaft seal, pushrod bush and the pushrod seal on the gearbox though, or at least check the pushrod for play.  Pushrod is the metal thing that sticks out of the splined bit in middle of gearbox belhousing when you lift clutch lever

You do NOT need to take the sump off and etc etc to prime an oil pump.

Just remove the dizzi and find the right size socket that goes over the oil pump drive shaft that the dizzi fits down on.

Get a socket extension bar and put that in the chuck of a drill or drill-driver.  If the chuck's not big enough grind down the extension so it fits.  Now spin the pump over until it picks up the oil and primes.  You'll know when it primes because it'll pretty much stall the drill.

Now refit the dizzi and praise the lord that you've not wasted ages messing about taking the sump off.

In fairness when I asked the question about priming an oil pump of a guy I know who does a lot of TDI conversions on T25s he said 'I never bother - just fire them up, if they don't prime up then there's something wrong with the pump and I've never had one not prime on start up'.

You could waste a lot of time trying to get a pump to prime on the starter - the engine might well not be spinning fast enough to prime a dry pump.

I have tried priming atotally dry pump before, I found it never picks up any oil as the gears just spin without enough suction.  Though this was me trying it out by hand on a brand new out of the box pump in a sump of oil, just to see what would happen.
I guess if it was spun fast enough it could work, that plus if it was bolted up more suction could occur?  Certainly worth a go before stripping the sump off, good tip!

I did the starter trick on my girlfriends polo but that was without a head on so it span over a lot quicker, wreeeeee splooge, oil everywhere

As I said, if its spun for more than a minute on starter with no result, its not gonna happen.

Best of luck with the conversion buddy!

Currently doing the same in my car! (but im doing it in a bit more than a weekend! )

Cant wait to read about how it all goes?! and how different it is to drive?!

cheers

i'm collecting info at the mo for my conversion

let me know how it goes / what too look out for

can i use my disy from my PB motor into the 2.0 bottom end

Theres an adapter ring available.. though i iamgine you can find a 2E dizzy easy enough? must be early type, late type only have 1 window not 4 for spark so will not do it 

[sidecarphil]

would just fitting a 2e motor not work ?? there is one on marktplaats( dutch type of ebay ) for 300 euro's but i think i could get it for 200

when i did mine i had engine out the hard way (split from box and all front end left on it was a laff but then you learn) swapped heads fit new clutch and back in in one day then on day 2 it was all plumbed in and wired up then wouldnt start so retimed engine then heard a metallic noise and engine stopped turning so thought valve contact so head back off all ok so head back on wouldnt start it tried fire but wouldnt (if only i had known i needed a 2e dizzy)
got 2e dizzy and it fired straight away
not a bad job to do once you know whats needed i just went about it the hard way

[rubjonny]

easier to start with a 2e, but if you get a later block as said bin the dizzy and fit a 2e one, the only other difference you have to worry about is the crank sensor, but just leave it in and chop the wires off!
