I believe the 170bhp TDi out the new vRS is available in the Mk1 Leon which is the same chassis as the Mk1 Octy (I believe)

Assuming the engine mounting to chassis points are correct can any one see any major problems fitting one of these engines to a Mk1 Octy. I know it's not a plug and play option but it could be an intersting conversion, especially if chipped!

I don't believe the 2.0 TDI engine ever went in a mk1 leon. Pretty sure they'd moved to the mk2 shape before the 2.0 engine started going into them. Could be wrong, but I thought all the mk1 TDI Leons were pd100/pd130/pd150/pd160 depending on trim level, etc.

Same is basically the same in the Octavia too I reckon.

why would you want to though?? The petrol vRS is 180bhp without chipping...

Both of you above are correct.

PS: Any conversion is possible Get all the wiring, engine, fuel tank and other ancillaries and chuck them all in a stripped out mk1 octy. Of course, it's in no way a straight swap.

Why would you want to? because i don't have bottomless pit of money for petrol and 50mpg vs 35 sounds good with similair performance if not better, torque rules!

The 2.0TDi wasn't available in the Mk1 Leon, they were all 1.9 8v TDis in different power levels.

The 2 litre has never been in Leon I, Octy 1, or Golf 4, so you'd be better off with a PD130/150 1.9 and a remap, much easier and easily tuneable.

You'll get better MPG and easier fitting from the 1.9.

It is possible, engine angle may have to be adapted slightly due to the larger cylinder head:rolleyes:

Surely anything's possible for you U18 guys, given enough cash?

But you do have a bottomless pit of money to replace an excellent engine with boring diesel?!

Torque is nice, that's why you want a petrol turbo. A 1.8T will hit peak torque at 2500rpm, and hold it till 5000rpm, then it's slowly reduced until it hits 7000rpm. A 1.9TDi will hit peak torque at 2000rpm, and hold it until 2500rpm, then rapidly tail off until 4500rpm is hit.

You need to look at the power and torqe curves, rather than just the peak figures.

Also don't be surprised if you start hearing rumours about a serious diesel shortage...... The current development of petrol powered HGV's is a strong indicator of things to come.

If the diesel torque is dropping that rapidly above 2500, how come peak power isn't til about 4000, and the acceleration rate is about constant between 1850 (where peak torque actually is) and 4000 (standard engine)?

I dunno, it's just how it is! I was just looking at this: http://www.awesome-gti.co.uk/rollingroad/graph/rr.briskoda_20.10.07/08.jpg and in comparison to a 1.8T torque curve, the torque does drop off at a relatively higher rate.

The 1.8T loses roughly 60ftlbs over a range of about 4500rpm, the 1.9TDi loses roughly 160ftlbs over a range of about 2500rpm. That's all I was trying to say.

I'm just commenting on general trends and rough numbers. I don't think you can deny that the 1.8T has a flatter torque curve than the 1.9TDi.

I'm only winding people up when I take the mick out of diesel! I'm a sarcastic git! I work for a diesel engine manufacturer so I don't hate it that much!

Sure the 1.8T has a lower rate of torque drop with increasing revs, but it's shorter geared, so the torque drop withi increasing road speed is closer, and Awesome have that car out-torqueing a standard 1.8T 180's peak torque from 1500 to 3500.

If your looking longer term cost cutting then you can't do much better than swapping a 1.8t vrs for a pd130 octavia which can easily be brought upto standard vRS BHP but much higher Torque.

Mine cost me about £1500 to change car and I am now averaging 50mpg against mid 20's which considering I drive 23-25k per year makes a huge difference, also my road tax is 1/2 of the vrs and my insurance is also 1/2 of my old vRS which in the 1st year of ownership has already out weighed the cost to change. I've spent approx 2-2.5k on mods which most are labour costs as I'm not mechanically minded, I chose to keep mine OEM looking for the extra supprise factor however its performance/handling wouldn't look out of place with a vRS bodykit on it if you prefer the looks.

Don't be worried about the torque curve dropping quicker in the TDi than the petrol as you don't feel the acceleration getting any slower as the BHP rises upto just over 3,500rpm, mine is just a generic map but could be setup better and much less spikey but I'm happy with how it goes.

My PD130 has had a generic map/panel filter/miltek exhaust to up the power from 130bhp to 185bhp

I currently run a mk1 vrs with revo generic map. Approx 210bhp and 232 lb/ft

I used to run a mk1 leon cupra tdi with revo generic map. Approx 190bhp and 290 lb/ft

I average low 40's tootling to work and back and low to mid 30's when giving it some in the octy.

I averaged mid to high 40's tootling to work and back and high 30's when giving it some in the leon.

In a straight drag race i would say they are very similar but above 80 or so the leon certainly felt quicker, it just kept pulling and pulling regardless of load. Once murdered a Civic Type r going down to Goodwood on the motorway. Silly speeds were involved ahem. It did mince the clutch after 15k tho on a new car.

The vRS has more engine character and practicality but the leon handles better.

I see my old leon most days and i think the vRS looks classier in a conservative kind of way. Leon's brakes look puny compared to vRS!

If longterm savings are your aim then i would say definately consider tdi option.

Jim:thumbup:

You'll see also that i did have a type r once too. Was new so may have been tight still when i got rid (only 8k on clock).

vRS and leon defo quicker in straight line.

Have you considered a V10 TDi conversion, loads of torque to be had there.....may make it understear a tad more me thinks.

Screw it! Get a mans Diesel.

Don't be daft, where would you put the rad, don't you know nothink.

Don't be daft, go for a Detroit Diesel supercharged 2-stroke, which will even answer the petrol heads "diesels don't sound as good as petrols" greeting!
