1.7d out - 1.9 1Y in - yee haa!

Post by **ringo** » 22 Apr 2007, 19:18

Drove down to Devon on Friday night to futbus Daves workshop. Used more oil than diesel. 250 miles in about 7 hours. Had to stop 5 times to fill up with oil - nightmare!

Anyway, the v. tired 1.7d engine made it down there for its final trip - and as usual it didnt let us down. It gave us 45,000 miles of fun that engine.

Anyway, never thought i would reminise about an engine!

We took out the 1.7 in about 2 hours - taking off the ancilaries and getting the engine under the van took longer than I thought.

Stripped the engine of bits for the 1Y and swapped them over. Changed the cam belt and did a few sensible things like that - then got to work putting the engine back in.

Bout 7.00 last night we fired up the engine - no problems starting it whatsoever! It was definitely time for a celebratory drink!

Today Dave sorted out the accelerator bits on the injection pump, fitted the exhuast and i sorted out the oil dip stick.

Anyway, she fired up and after a test drive and i few tweaks we were off back up the M5 for 250 miles back to Nottingham.

The 1.9 pulls like a train - hills didnt really slow us down. Im chuffed to bits!

I have a few issues regarding the wiring - and the buzzer of doom came on temporarily when we slowed down at the motorway services (think that might be a sensor issue as the oil level was fine). Apart from that, its great!

Thanks to Dave futbus for giving up his weekend and for him and Rose taking us out on Saturday night - see you at VanWest!

I was planning on an AAZ to convert my 1.6CS but after much searching
and weighing up of costs and parts needed I am starting to get a bit
doubtful that we can really do it.

I have been offered a 1.9 1Y at a reasonable cost and as far as I can figure out from reading the previous posts I can swap out all the bits sump etc etc from my current CS engine needing very little in the way of new bits - is this right?

The information section though lists the 1Y as needing the ECU - can this
be bypassed???

I know this won't give a massive power boost (compared with AAZ) but it
would be much better than my current 1.6 and cheaper/easier?

Also will my current gearbox be ok with new engine or should I look to
upgrade it - if so what code box should I be looking for?

Many thanks for the help!

Hi Graeme,

I cant really help you with the technical details like gearbox codes - but someone will!

The bits off the 1.7 diesel went straight onto the 1Y - no problems whatsoever. apparently, 1.6d is exactly the same so you shouldn't have problems there.

My 1Y does not need an ECU - there are some wire that i still dont know what are for, but the engine runs fine without them! I will find out one of these days.

Easier cheaper than an AAZ ? Yes. No searching around for jx bits required. Engines are fairly cheap too. Quite a few people have done the conversion and agree.

My gear box is the same and handles the engine well. Top end speed is the same, but its a different van to drive - so much more fun. It actually has some umph now.

Im still tempted by an AAZ - and if you have time and money to collect the parts then personally i would go for it. For me, i needed an engine change quickly - so the AAZ wasn't an option.

Thanks, seems like this might be the way to go, I'm sure I'm going to come accross a few more questions!

Is there a step by step guide anywhere or is that just being too hopeful?

Hi Graeme

If you look in wiki you might find something in there that is useful also give Mr Futbus a pm and see if he can help you.

I'm glad I've seen this thread! Got a very tired and oil consuming 1.7D myself and have been trying to figure out which conversion to do. Everyone says AAZ, but as you stated its a bit of a pain having to collect so many other parts from a donor JX engine.

If you have any pictures of the conversion I could have a gander at that would be cool and also offer any pointers if I was to do a similar conversion.

Also good to see it doesn't require the ECU as I was informed from other sources it was?

Anyhow have you just bolted the 1Y engine used the 1.7 exhaust, manifold, water pump? alternator, air box etc?

Any help would be great

Yes - except the alternator isnt the same (so no for that). Mine came with a water pump so i dont know about that.

When you get an engine, make sure its got the alternator on it.....

PM if you want more info - i havent got any pics unfortunately.....

cheers for that,

If I manage to get an engine soon I'll be in touch!

The 1Y would be overall a lot less trouble than an AAZ, with its turbo to look after and of course, its working under higher load and has been since it was first built.

If the turbo is mounted higher up on its own manifold rather than the JX manifold and pipe, it might be less trouble, as I'm pretty sure these low slung JX turbos are 'trouble' just waiting to happen - but then you have to do a bit of work for the exhaust side of things.

i fitted a 1y in last june,did all the research on here and had no probs at all,"garrick",if youre ever over stoke you are happy to have a gander at marladys van,and i could give you a few pointers/answer a few questions duck..........but my conversion went like a dream,and apart from having to change the box,because i had the worst gear ratio possible....there wasnt too much to worry about,marlady went newquay in ours a fortnight after fitting it,the beauty of these engines are they are cheap and i now have a 1983 van with a 1994/5 engine in........reliable.reliable.reliable........and does s**t loads to the gallon

Cheers for the offer there. I've actually just fitted a 1.9 AEF (very similar to a 1Y I beleive). Anyhow I've got it all in and running, just have had to replace the clutch slave cylinder which hopefully should be done this afternoon. I'd be interested to know what gearbox you've put in and what box you had fitted originally.

Thanks

Post by **ringo** » 22 Jun 2007, 08:32

I too would be interested in what box you have. I still have the 1.7d box - not sure of the code.

I get slightly less to the gallon that i did with the 1.7d - which im a bit dissapointed about to be honest. I'd like to change the box at some point to see if i can get better mpg and not ruin performance.

Anyone going to the techy weekend ?

Ringo

Ringo can you tell me where the techy weekend is thanks.

Post by **oldiguana** » 22 Jun 2007, 08:58

not sure what box was in originally owducks,its still buried somewhere in't garage,but when i looked up the code on brickyards gearbox ratio chart,it was the worst ratio possible(low top end),but for a 1.6 diesbag it needed it,but the box i put in was a 1.9 Aircooled box,cruises happily around 55 now which is more than enough for us,but when i fit marladys alloys im going to go up a tad in size with them to give me a bit more,as for the economy we get craploads to the gallon,cant really be exact as the fuel gauge and odometer dont work!!!!!!lol,but marlady went dine newquay in it last summer and did better than our diesel golf mpg wise...
