Hello All,
I have had a quick search I know it is probably a well worn question. I own a 1.6 turboed van and would like to used an engine out of an 1.6 N/A of a similar year (E reg) with as much of the turbo components fitted as possible. The 1.8 Ford diesel engines used to have sodium valves fitted on the turbo 1.8. Is there any hidden problems like this on the VeeDub engines?

You can carry out the conversion you are thinking about BUT the normally aspirated engines DO NOT have the oil spray cooling devices fitted to the con rods, unlike the TURBO engines which are fitted with these as standard.

In simple terms you may get away with putting a turbo on an N/A motor provided you drive it sensibly there after....


Regards

Are you saying you want to stick the turbo etc from your '1.6TD' onto a non turbo engine ?

Yes he does Mick. -------------

Me Thinks you need togo to Specsavers, Lol""--------------------

you CANNOT stick a turbo on a non turbo engine and use it!

Ah Mr Grumps, me thinks you want to read the post a little more carefully and not make assumptions...He did not say he wanted to fit the TURBO, mearly to use as many bits from his td as possible . ie sump,brackets etc, which is why i asked the 'pertinent' question..

Therefore i accept that you do not need to visit specsaver though perhaps a few lessons in english wouldnt go amiss

As Billy says no can do

mike

You guys say no can do but its been done with a 1Y.

Ask Mr Hutch.

OK, thats a 1.9 and not a 1.6, but if i was going to all the trouble of changing an engine, there is no way i would put a 1.6na in - especially as 1Y's are so cheap.

Put a 1Y in with the turbo on......

Or, just do it properly and put a AAZ in.

Hi Ringo,
not mocking you in anway, But with reference to the 1Y with a Turbo, the AAZ an 1Y are virtually the same engine, on the underside of the engine block there is the engine size stamped or moulded onto the block face indicating 1.9D/TD. If it has this. 1Y can take the Turbo setup.
As Fritzz said it has the oil spray jets on the bottom of the cylinders enabling to keep the undersides of the piston crowns cool, as a Turbo engine develops mor heat.

considering that the original turbo engine already requires sensible driving, I don't know how much driving there would be left in the converted n/a block at all ..sensible or otherwise.

Thanks for the information guys, this is the exact information I was looking for. While I would like to put in an 1.9 AAZ I already have a 1.6N/A on the shelf. My original TD engine has a crank problem so I may just swap the crank around now you people have confirmed about the J jets. J jets are usually used in conjunction with gallery cooled pistons, do you know if this is the case with the VW engines? Is there any compression ratio difference between N/A and blow 1.6 engines? J jets usually also reduce the oil pressure severely how have VW coped with this problem, are the oil pumps different?
kind regards
Paul

I'd never think you were mocking me Jeff - I fully respect your knowelege. However, im not sure i agree completely. The jets help for sure - but i dont know if that means you shouldnt turbo an engine without them if its cooled properly.

Not all 1Y's have the TD part on them (i've had two) as i think you are eluding to.

I'd wait for Mr Hutch to comment as he's done it.

Good luck Paul - keep us informed!

My van originally had a 1.9 N/A engine fitted with a Turbo (i was told it was an AAZ it wasn't) It lasted me a few months then went bang.. So yes it probably can but make sure you get it right - this one had no oil spray jets and ended up burning as much oil as it did diesel!!

1.6D "CS" engines do not have oil spray jets.
1.6D and TD pistons are dimentionally the same, but have different part numbers, without digging for ages, I suspect that they are treated differently so the TD ones handle the extra heat produced when used with a turbo.

1.9D "1Y" engines do have oil spray jets, however..

1Y and AAZ con rods are different.
1Y and AAZ Pistons are different.

Pistons are dimentionally similar but not the same, the AAZ pistons are treated in a way to make them more resilliant to the xtra heat produced by a turbo engine.

Basically you can turbo a 1.9D 1Y engine but be carefull.
I wouldn't turbo a 1.6D, but a 1.7D does have oil spray jets and would turbo, but as the 1.9D "1Y" don't go daft.

as bax says, do it but don't be a goon

It's not got coated pistons, and really wasn't meant to be blown, but if you are steady and don't want to build a really hot engine it's ace

I heart 1Y's

(thats why the latest project is a VAG 2.0 petrol )

oh and forgot to mention, make sure you use a 3 hole gasket on the head
