jx upgrade to aaz/1y-z/ahu or agg/2e yor views? ?

[Cyrus]

Ok I've read loads about upgrading but just recently looked at going 8v gti aggressive.
these are my thoughts.
aaz Pros. Easy upgrade. Cons hard to find a good one
1Y/Z Pros more modern reliable good Mpg. Cons lots of wiring & gearbox lets it down
AHU Pros as above Cons. As above
Petrol Agg/2e Pros higher revving so gearbox less of an issue?? MPG?? Wiring? ? Additional electronic fuel pump?? Torque? ?? Exhaust fabrication /loudness???
Please add any other ideas pros cons etc as I'm seriously thinking of going petrol 8v gti
Thanks cy

Thanks cy

No wiring other than stop solenoid on 1Y and your normal sensors, your gearbox will most probably be the same as mine as mine was originally a JX, no issues with the gearbox at all.

Thanks, this just the info I'm after, also less downshifts going up hill would be nice.
another thing that is a pro for the gti for me is the cost and availability. I can pick up a whole car for less than £500 so could possibly break even.

No one else? Feedback on gti conversion? ?

I did a 1y conversion from 1.6td its a simple conversion the only parts you need are a straight swop over .Or you can use the 1y inlet/exhaust manifold .Requires fabrication for an exhaust down pipe.Performance about the same as a 1.6td but more torque aprox 35mpg.If i had the choice i would go for a 2E or AGG 8 valve engine this can give 100+bhp 0r more performance cam shaft option and can be LPG converted.ECU&wiring loom There are diffrences in inlet manifolds to give clearance away from the chassis rail the exhaust manifold needs a down pipe fabricated to rear silencer.You need a diesel bell housing&spiget bush.Engines are cheap easy available .Oh injection engine swirl chamber or fuel tank requirement.Should have done this conversion when i had a 2ltrcu aircool auto that went t***ts up with oil leaks and low MPGs spent pounds & time and work making a solid DevonT25 but sold it on.Always thought i should have converted it to water cool whilst welding and reparing the body work.

IIRC AGG has a linear torque line/curve between 2 and 5k and makes more/same than AAZ, have a google.

Gt3i will give you well into 30mpg, can be gassed very easily and cheaply and is generally a lot more enjoyable to drive, have had JX/JX with a GTD pump/AAZ/JR and Gt3i was helluva lot better than all of them.

Only thing that bettered it was the 1Z Tdi BUT it had the standard gearbox in and was dogshit on standard gearing, new box with differing ratios will cost you a pretty penny, for same money as a rebuild with new gears you could fit a Gt3i on lpg and get alot more smiles per gallon.

Rest of conversion? You can do the wiring loom infront of the TV and fit it in a long day or easy/slow weekend. Easy enough if you arnt colourblind/stupid/both . Additional fuel pump goes as far as putting in a mk2 gti pump and pot.

If we knew a bit more it might help.

is it your daily driver? miles per day? main useage? second car? distance travelled daily? etc etc

A very simple way to improve a JX is to fit a GTD pump and lines, makes a very noticeable difference.

Cheers Elvis,
The camper gets used more in summer 20-30 miles per day and for weekends aways / holidays / festivals etc. and as a 2nd Car.

At the mo the JX is running okish, blowing exhaust fanimold, leaking oil at various places. For the cost of sorting everything out on the JX I could purchase an AGG and fit it myself with assistance, over a week off work. Wiring doesn`t scare me as have made looms for industrial equipment before and I have an electronic back ground. I can also weld and have a welder.

I really need a more relaxing drive, TDi would be perfect but as you state will be let down by the Gearing. once you get into the realms of flipped passat box etc My pockets will have big holes in them!!

I am After Around >25 MPG with Diesel Like torque Fairly simple upgrade for around £500.

The only things I`m not too sure about is the swirl Pot, I know what they are but fiiting them into a tank is the question and Which exhaust for a peaceful journey ( I`ve grown out off Cherry bomb Exhausts!! )

The 1Y would be simpliest but again hard to find a good one and AAZ`s are getting like Hens Teeth.

I replaced my JX with an ADY from a Passat.
The ADY is 2e/agg hybrid.

It's bloody marvellous!

I cruise around at 50 - 70 kmh in top and it's smooth, relaxed and quiet as a mouse. Then if I feel the need for speed I give it a big bootful and she'll go over 170 km.

Regarding the swirl pot these can fit external to a fuel tank http://www.ebay.co.uk/itm/2-Litre-Fuel- ... 4853762aaf" onclick="window.open(this.href);return false; .Some think like this prehaps.The silencer for the JX may not be suitable due to not enough back pressure. .Petrol engines need it to get the best out of it in terms of performance &mpg.I used the 1Y engine camper a lot on motorways it was okay but on occasions i could have done with more performance up hills.My choice would be ADY as stated.

Mine has a fuel tank from a petrol injection T3.
The exhaust is the Passat system with manifold going forward to the middle box and then back around and into the Passat back box which side exits just in front of the LH rear wheel.

It has the correct back pressure and nearly the correct length.

As previous, mk2 gti pump assembly has built in swirl pot/header tank aswell as filter holding quite a bit.

Save your money on Ali swirl pots and/or 2.1 tank, 1.9 tank still has a sump of sorts anyway.

All this info is priceless, thanks

[Cyrus]

Is the agg Immobilizer simieto the Tdi ahu one?
Eg do I need the clocks,ign barrel / key, Ecu, injection all from the same car or could I buy an Ecuador loom from one car and engine / injectors from another???

Have you any photos of the exhaust? I've read up and this seems a bit tricky. Your idea of passat going forwards seems sensible
