Opinions wanted Mk1 TD

[sports racer]

I'm really interested in this thread. Any idea what sort of power you'll have? I'm not asking from the boy racer point of view. My MK1 has a 90 hp 1.8L motor and I do 180 ks each day on country roads. I'd love something that's very economical but still has decent power to take on the hills and overtaking the slow traffic. The torque and economy of a diesel really appeals to me.

I'll do that but only if you could block Preen from seeing it... he said some bad things about a chef once... I'm a chef and i was offended...

This is all very interesting. I like it.

Haha, my best mate is a chef. He's the one that cooked my GLD.. The bastard.

Hey mate,

With some head porting, a decent turbo setup (like a large VNT or a large single turbo with lag, or a clever but hard work twin turbo setup) and good pump tuning, 200hp is possible from a 1.6 TD. The 1.9TD (not TDI) like I have in my mk3 seems to have an upper limit around 260hp.

My mk3 is making 120hp and 300Nm at the wheels with a Garrett T3 (with plenty of potential). If I wasn't concerned about replenishing my savings after buying the Octavia, I'd probably think about converting my old mk3 to something more stock before selling it and keeping that engine for a mk1 - cos like you are thinking, that much hp and torque in a light car is just plain fun.

Back to your main question though - a 1.6TD with a k14 should be able to make 90-100hp easily, running around 20psi boost, which is easy to run with no engine mods at all. The most important thing is to tune the pump to deliver enough fuelling and have a decent exhaust and intercooler setup.

Ive just uploaded the gov mod video into a new thread... Hope you guys enjoy

Well its done, and not without a bit of nostalgia for the ol 1.5D donk. It has (and still is) a very good motor and is a perfect pairing with the chb cordoba gearbox.

Out with the old


And in with the new


I used the back way to get the motors out and in.

My helpers.....


Install complete


Things to do now include:

replace gearbox drive shaft seal holder (the green sheetmetal one) as its damaged and leaking
install washer bottle - I have a petrol washer bottle and mount to go behind the battery
source and install a cordoba air cleaner box (thanks mollins for the idea)
wire up reverse switch
mount fuel filter
mod alternator to run the tachometer
exhaust
intercooler
egt etc etc.......

The car pulls really well in 2nd and 3rd. In 4th and 5th it isnt brilliant but has a very laid back feel. Boosts to 10psi

Well Done Buddy

Thats too funny... what are the odds? i'm putting the Turbo into a Mexico Beige GLD... although i have owned 3 beige Mk1s... Awesome work mate... I'm getting closer too...lots of little subtle differences between the motor out of the passat...

On that note does anyone think i will have any trouble using the Passat Sump? Its lower than the golf sump but not by much... My golf is lowered by a inch or two...

I noticed when removing the drive shafts that if I turn one flange, the other turns in the same direction. I can get the other flange to turn in the opposite direction only if i put it in gear (and theres a bit of friction to overcome). Does this indicate that there is an LSD in there or just that the spider gears are stuck? I will replace the flange seals as they are leaking so I might be able to tell from that..... Gearbox code is 8A

Not necessarily. In a differential, if the input is locked, then the wheels will turn in opposite directions as the average output speed is the same as the input speed. If the transmission is is neutral, then as long as there is nothing stopping the input to the diff turning, the outputs should turn in the same direction.

You can check for a diff lock or LSD by having the transmission in neutral and then turning each output flange in different directions. If they do turn in opposite directions then there is no diff lock or LSD. LSD usually requires a fairly high torque input before it starts working anyway.

with this one, JustMarks and my dad, thats 3 beige GLD's with turbo's this year!

[hiho]

Without the benefit of red paint, the beige mk1 diesels require turbocharging. Mine has red injector lines and red turbo oil drain for an additional performance boost.

The fuel consumption is phenomenally low, but performance wise it is probably on par with the 1.6 petrol golf.

I will be fabricating a downpipe or two and will need a welder. I have been advised that I should purchase a tig welder instead of a mig welder. My limiting factor is the power supply is limited to 1600W continuous and 2400W for 30 minutes. Again, opinions are requested

[gldgti]

hey man,

if you have a mig thats fine. no real need for tig for MS exhaust stuff at all

[sparkie]

I agree with gldgti, I have a mig. But just after I bought mine the 'new' inverter welders came out. They are much more energy efficient and lighter in weight (definitely and issue). I am told they also do tig and mig welding. I have kicked myself for not waiting as I knew they were coming out. Also buy a solar-powered welding helmet, so much more convenient than having to flip the screen up and down every time you do a weld! Once you have a welder it's amazing how much you find you need one! Get the best you can afford!

[Preen59]

Just buy a MIG.

If you can, copper transformer, 250amp single phase, remote wire feeder.

You get what you pay for with these things and the more you spend the better you'll get (And the better your welds will be, too).

Your little helpers are awesome! my kids would love to have them as pets..

[hiho]

Thanks AP, they're little terrors!

Mark, what parts do you need for your MK1 TD swap? I highly recommend you do it. Do you have a 5 speed box and mount? I will have a spare 5 speed mount soon if you're interested. Also, do you need a downpipe? I will be fabricating two for myself so my stock downpipe will be surplus to my needs.

If you need any other parts, with the strong aussie dollar, I suggest looking at the for sale section on vwdiesel.net

Do you have any photos of the motor while it was still in the passat?
