Mk 3 Ibiza ASV Engine Change

[PaulMyCock]

Hi there,

Please can anyone offer some advise or be able to assist me in achieving my goal of getting the best value for my money as my TDI has cost a small fortune up to this point rectifying other peoples neglect...

I own a Mk3 Ibiza Tdi Sport (110bhp ASV) which has just snapped a valve. The engine is totally standard.

Here are the options as I see it:-

1) Replace the engine as it is and keeping it as simple as possible ie. finding another ASV lump.

2) Find a different engine with maybe more bhp and making the effort and grief I have had so far, worth it a bit more, if this is possible...

3) Find a donor car (preferably with 150bhp) and find a way of making it work ie ECU, engine mounts etc...

My dilemma is that ebay is full of mostly rubbish with high mileage so finding a donor is quite hard work and I want to make sure it is worth it. Ideally I want a low mileage smashed up 99-02 Seat, Skoda, VW etc...(yes I know, good luck finding one cheap).

I have looked on quite a few other sites with not much joy as most are too much money.

Can anyone advise how difficult it is upgrading the ASV to maybe a ASZ or similar?

Whether its best to put another ASV lump in and maybe modify the turbo if it possible with a pd130 or pd150...?

Or the boring option which is stick with what i have and keep it as simple as possible...?

Does anyone have any ideas or advice that would be greatly appreciated.

Does anyone have what I am after?

What would you do?

Many thanks

you can buy full recon engines for as little as £800 for the 110 lump, buy one, stick it in - keep it simple!

ASV is the most powerful of the non-PD engines, the TDI 130 and up are PD engines which would need a lot of changes to the car. The fuel system is completely different and they are usually mated with six-speed boxes, so you'd need to change the gearbox as well. This may need drive shaft changes, I'm not sure.

 

[sssstew]

yes agreed with the guys above. Get a good 110 to put in it, let it settle in then you can look at tuning if you want more power later on.

 

[PaulMyCock]

Thanks for the advice...

I have access to a good welder and together with me and a talented mechanic I know, I thought if I had a complete car then we would be able to make it work, with a bit of messing around and end up eventually with a 150bhp+ mk3 and as I already have the Cupra interior etc, it would of been the final touch.

Your probably right, I think I will keep it simple and buy a recon 110 ASV lump, although I am tempted to rebuild my block.

Does anyone have any recommended suppliers of good recon engines or will it just be a case of pot luck online search?

Whilst I am here, what simple upgrades can you do to increase power apart from a remap?
Would it be a uprated turbo and injectors and do you recommend a hybrid or maybe modify to fit a pd130 or pd150 or again, should I stick with what I have...

So many questions with so many different options, what to do......?

 

[allh2k]

If the engine is to be replaced anyway can you try to fix the value n any other damage your self?

I'd love to pd150 turbo, uprated injectors, remove egr/cvv, exhaust n other bits with a remap

yeah like has been said :-

Hybrid Turbo or PD150 plus mani
Injectors
Exhaust
then remap it at the end to take in account of all mods.

Will easily see 150+.

Don't the pd130/150 engines have the same mounting points as these asv's anyway?

 

[Muttley]

It's quite likely that the mounting points are the same for all engines in the Leon shell. The problem with replacing a distribution pump TDI (90 or 110) with a PD TDI (130, 150) is that there are other parts of the car that will also have to be changed to make the whole thing work. ECU of course, fuel system (tank, lines, filters cooler and associated pipework and wiring to power the lift pump in the tank) and I think the PD engines come with a FMIC rather than the SMIC of the non-PD engines, which may mean a change of front cross-member. The engine should be changed out as a unit with its associated gearbox too, which may mean changing the remote gearchange (cables and stick).

 

[basstard]

Stick an ASV in and mod the shite out of it. With a bigger turbo, injector nozzles and IC you're easily around 190hp [mine is/was 140hp with the chip only]. I know for sure the stock injector nozzles are good for 160+hp [when using a bigger turbo]. IC is a must since the stock one is ridicolously small. Clutch also since it won't take that much torque [mine took 183k km of abuse with remap and only started slipping the last few weeks, but I only had circa 300Nm].

Using another engine is gonna be a PITA for the ECU part alone. Let's suppose you can fit a 150hp in it, with gearbox and everything [good luck at fitting the stock 150 IC in there!]. Then you'd have to code all of the dashboard, head unit, climate control, alarm, traction control, abs, power windows and god knows what else to work with the ECU. You know about someone who can do this for you?

 

[Muttley]

To be fair, Carlo, I think it is only necessary to pair the ECU with the immobiliser control unit, which is part of the dash panel. I haven't done it though, and I could be wrong . . .

 

[M1KEH]

Or just remove the immobiliser from the PD ecu, really not that hard.

 

[basstard]

Muttley, I don't think so, I could be wrong tho.
I mean I'm not even sure the connections between all the stuff I said earlier are a straight plugin with a different ecu. ASV engines use EDC15, the PDs are EDC16 or even 17 IIRC.

 

[basstard]

Or just remove the immobiliser from the PD ecu, really not that hard.

Or just swap the key transponder from the donor car key to the ibiza one. That is assuming the ECU can be used, as said.

 

[M1KEH]

You get different variants of ecu's with different immobilisers. The pd's can have edc15 also. It's all about matching up immobiliser 1 2 or 3. But for this swap I would just disable the immobiliser. You will need the engine loom for the donor engine though too.

 

[basstard]

Obviously you need the wiring loom. But then you also have to mate that loom to the rest of the car and I ain't sure you can do that easily. I'm pretty sure you have to do a bit of coding to get a different dash to work, same goes for the radio and I wouldn't be surprised if there's other components that need the same.
