Gearbpx for Cupra TDI

[Bi0H4z4rD]

Well, i have heard somewhere that the 2002 TDI Sport gearbox was capable of very high end speed when put in an Cupra TDI. Does anyone know anything about this, or about any other mod that can make it gain more end speed? I dont want to earn the speed by raising the limits on the map, so a mechanical solution is imperative.

Just for info, my cupra gets up to 220km/h (around 130mph).

You top speed seems a little low for the car.

Ive seen figures on the clock of 152mph which taking into account my speedo is around 10mph out is 142mph but that was on a slight downhill. Even so I can manager circa 140mph on the clock without any decrease. Mine is a FR TDi that has 20bhp less than yours and 20nm less.

As far as a gearbox goes, the Sport 02-53 plate 6 speed gearbox does have high gear ratio's indeed. The cost of a 2nd handgearbox and fitting imho wouldnt be worth the extra 5mphish that you would get looking at your power figures

It does beg the question, why? Track use?

Yeah, i know the FR has more top-end speed. Indeed, the Cupra has the first 3 gears longer that the FR, and it happens the opposite with 4th, 5th and 6th gears (the Cupra has shorter gears on these), so the top-end speed will be higher on a FR. Can say this since i have ridden my Cupra, and 1 minute after that, a new FR (both TDI) so i DID notice that.

I got a picture of a FR TDI that went up to 270km/h (around 160-165mph) supposed to be with this gearbox mod. Thats why im asking! Just want to know if this is a myth, a photoshop trick, or can be possible!

Nope, just i like to try these kind of stuff if truth.

Doubtful, as most tracks you cant do this sort of speed on with that much power.

Book figure of a Cupra has a higher top speed. Remapped this should stay the same im afriad :S

The FR gearbox is geared to around 163mph from what I can remember, whilst I always remember EdButler's old sport was geared to 196mph

Id be tempted to see what all these hyprid monster 250bhp+ TDi's could get to with one of those gearbox's!

 

[Bi0H4z4rD]

Nice to hear that! Btw, i tell from myself, my car with stock ECU could not go any further than 225km/h (130mph), so im not basing this on a book or someone telling me. So maybe you think i should try "importing" the 4rth, 5th and 6th gear from a FR TDI gearbox? Mean, do you think i could do that?

This would be quite interesting!

I will try to find technical information about gears ratios for FR and Cupra gearboxes.

 

[rashcupra]

i appreciate what your trying to do but why the hell would you spend all that money to do that speed 1 time!! and where would you do it????

130mph is a poor top speed for a cupra tdi! wanna check your map and get it customised for more top end grunt!

if i were you id look into fellow derv vag cars and look at the top speeds of them all and pick the 1 with the best top end as that will obviously have the better ratio for what you want

TT, A3 ect

Isn't the manufacturers quoted top end 134 mph for the Cupra TDI?
I've never really paid any attention and have no need for the Ibiza to be doing them speeds, its not the most stable of cars when hitting high speeds!

 

[rashcupra]

i thought the tdi cupra was 145mph ish iirc

 

[John-Cupra_TDI]

Surely the cost of doing this would by far out weigh the gain, a few extra Mph! Would rather have the car accelerating quicker than a higher top end.

You may be right, will it have a figure in the Handbook you think ?

According to Seat ;
pd160 max speed 200km/h = 125mph
pd130 max speed 208km/h = 129mph

Gear ratios ;
pd160 .pd 130
0A8.A 0A8.C
3.357 3.769
2.087 2.087
1.469 1.324
1.088 0.977
1.108 0.975
0.912 0.814
reverse
3.990 4.549

Cupra PD160 max speed is 137mph according to Seat

So you see i was right about the stuff! And guys, i dont know if the gears are as expensive as you may think.. I will ask my local dealer for price on sunday-monday. I guess that it should be around 120 pounds (150 euro) just for the gears. Of course if they cost over 300 pounds i will inmediately discard the stuff!

@rashcupra: In diesel engines, i dont believe that they should be set up too high on revs to gain speed, as it can be done on gas ones! Btw, are u sure that a 1.8t gearbox (to mention a petrol one) will fit a diesel engine? Have in mind that they work on different rpms, and the result of putting a petrol gearbox on a diesel engine can be in very very short gear ratios (no speed at all)!!

Mine was fine.....

Bi0H4z4rD: The FR doesn't have a higher top speed than the Cupra.

The information I have from Seat and what it says in the brochures is:

Cupra PD160: 137mph
FR PD130: 129mph

The Cupra also develops it's maximum power at a lower RPM than the FR. Replacing the 4th, 5th and 6th gears will mess up the final drive ratio as the Cupra and FR both have one ratio for 1st, 2nd, 3rd and 4th and another for 5th, 6th and reverse. They are both different in the FR and Cupra and the Sport only has a single final drive.

i ment to say derv (diesel) not 1.8t imo your wasting your time and if you plan on doing them top speeds all the time i exspect to see your car like this

each to there own but im much more an acceleration enthusiast as this can be used sensibly!

 

[muddyboots]

Bloody hell, that doesn't look good.

By the way, the original TDI Sport box was geared at 37.5mph/1000rpm in 6th. One of those bits of trivia I remember
And the max speed of the TDI 130 Sports quoted by Seat was achieved in 5th, I guess the standard mapping didn't have the grunt to push 6th beyond those speeds.

But like Rash says, I also much prefer the sensation of acceleration; big speeds scare me as the risk of mechanical failure (tyre blowout etc) means it would be game over instantly....did 130mph in Germany but tbh I didn't enjoy it at all.

Oh it's not bad but when compared to my Scooby which is very stable it's a little twitchy on back roads. You also know your shifting in the Ibiza where as in the Scooby you look at the speedo and realise your going faster that your thought.
