1.6td to 1Y swap

[jebiga41]

sorry guys checked out wiki etc but still can't find the answer do i need a 1.6 exhaust manifold to install the 1y or can i use the 1.6td setup and just try and bypass where the turbo would go i take it i can use the jx sump etc and get the spigot bearing but is there anything else i need regards 1.6 non turbo stuff thanks

To be honest, i think your a bit mad putting a 1Y in and not an AAZ.

I had to buy another van to get the bits needed for a turbo conversion!

It is possible to use the whole turbo setup on the 1Y (MrHutch has done this with success) - but you will need a new injection pump i believe that has got an LDA on it for the turbo boost to work..

Out of interest, why are you going the 1Y route?

hi am going the 1y route as as got one off my uncle which is running well and just blown my engine so its a matter of neccessity, am considering doing the same as mr hutch and turboing it but for the moment was thinking of the standard 1y route as want to get back on the road asap and seems like a good reliable conversion altho will lose some hps. do i need a non turbo manifold to go this way?
Also is it much more hassle to to turbo it? And would it cost much more considering have to get a injection pump and injectors?

I'd ask mr hutch - he's a top fella. PM him on here or brickyard - he's mostly on BY i think....

If you want to get the NA way then you will need inlet and outlet manifold, air box and probably a new exhaust. You will also have to block off the sump oil return hole....

I dont know if you can use the 1.6 pump and injectors - but that might be an option...

Ask Mr Hutch.....

jebiga Ive done the conversion 1.6td to 1y on my doka about 6mths ago.

I used the exhaust manifold and turbo from the 1.6. Then I got an inlet manifold from an AAZ and used this in place of the 1.6 inlet manifold (different port shape). Ive used the standard 1y injector pump (no lda) and blanked off the LDA tube from the AAZ manifold. Every thing runs fine. Sometime Ill get round to putting the AAZ pump on
Good luck!

thanks dude the engine is in the car so have everything do i need t25 na manifolds or can i use the 1y's sounds a bit tricky might got the turbo rout as can probably pick up the aaz stuff easier than t25 was talking to mr hutch he went with this set up

the 1Y and aaz blocks and internals are nearly identical. I used AAZ (1.9td) pump and injectors, JX turbo and manifolds

You will need to slightly port the inlet manifolds to give a better result.

power is fantastic, reliable and crusies easily at 70mph on the motorway while still givin 35+ mpg

(I have the 5 speed box and larger rear wheels/tyres) the tourque you get is more than enough to get away with it!

so probably an easier rout by the sounds of it will let you know how i get on paul

thanks chilla seems theres lots of options only just saw your post just now am getting more and more confused but seems like a good idea did you stick with the 1y injectors and does the turbo kick in?

[ringo]

The 1Y inlet wont fit without some serious fetlling.

I think if you have a doka you will get away with it - but definitely not in a standard van...

Yep kept the 1y injectors in and will change these when the aaz pump goes on
Can hear turbo spooling up but to be honest I doubt its doing that much. I expect the engine produces just over just over the 60hp standard.

The aaz inlet manifold option was the quickest fix to get me back on the road and I got 1 from my local scrappy for 15 quid

Turbo will do virtually nothing except clean up nasys out of exhaust, you need a turbo pump for it to be useful.

Hey jebiga41. check out my post under "1Y exaust size". I used a 1.6 intake but i matched the shape with a gasket, then welded up the extra meat needed. Then just cleaned it up with a body shop air sander[ big long surface to be able to plane it flat] and then used some epoxy to make it pretty. The only other thing that isn't stock was the injection pump. I replaced the 9 mm head with a 10mm. I am sure i have about the same power as a 1.6 turbo without all the plumbing, special oil etc, etc.

finally got it in on the road on the 2nd so shes up and running. Used baxters pump arms and as the engine had a garret turbo used a siimilar oil return set up using stuff from a local hydralic guy for the oil return from the turbo. Also used the JX inlet and exhaust system with turbo loking to aquire a aaz pump and injectors to turbo her. Whilst puttingon the accelerator cable lifted the shim for the revs from the pump but managed to put it back and adust it by ear. but not sure if the revs are set up right as will do max 6o mph maybe a little bit more down a hill, the jx did more speed wise but seems to me thet the accelareator cable almost feels like its to short as if i go up a nodge n the pump revs the engine feels like shes revving to high at idle but at the same time feel like she could rev a bit more but no more room to pull the the lever. what kind of mph are you guys getting on a 1y? but apart from that she seems ok maybe burning a bit of oil but thats it any ideas. altho I'm running a standard 1.6td box i have 15" heels so don't think its the gearing thats stopping it will post some pics soon thanks for all the help before Paul

Good work!

I've now been driving my 1.7 ky to 1.9 adg swap for a couple of months now. A month ago i put in the transmission
with the parts i got from Aiden. A 5 speed syncro box with a 4.86 R&P rather than the 5.5 it originally had. I also [as i already posted] redid the pump with a larger head and with governor and timing tweeks. It's not fast but certainly faster than before. Acceleration is good enough to keep up in traffic, go up highway ramps and past trucks and gits driving toyota corollas. Top speed is about 75 but most importantly i can cruise at 65-70 at the same rpms as before.
When i get a bit more cash i will probably get a super pump built .I won't get more top end but should have better acceleration.

what ringo were you towing another T£ I take it you were talking mpg's oh dear keep jumping from here to the brickyard replying to you
