Little help guys, to bring you up to speed, I blew my pd130 turbo, and instead of getting a like for like replacement, i got a standard VNT17 (pd150) turbo, brand new from TD. I have had this fitted, and have now covered over 500 miles on this......but altho the performance feels similar, it seems to be using more fuel, and doesnt sound anything like it did before.

Is there something wrong? would a remap fix this?

The car might be adapting (good old adaptive ecus) to this new bit of kit. Give it some time. Mine was a little like this when I ran my first hybrid on stock pd130 mapping. Was a reasonable 150hp but nothing special and not brilliant on fuel. Mapping at Jabba soon sorted it though.

the thing is the car is already running an rstuning remap...cheers for the advice by the way....

Well, the way you were posting above, I assumed it was stock. :P You might have just answered your own question. Remap for 1 turbo, change it, still using same mapping? It will need doing.

ah - its not a hybrid pd150 so assumed it wud run fine, but ye, guess your right....hope it sounds ok once its mapped, dont sound right at all...

Sure it's not a hybrid but it will be a stronger garrett turbo than the stock kkk turbo it had originally. It runs more boost as stock on the pd150, and probably has a quite different boost pattern through the revs. I would get the mapping looked at for the running issues, and hopefully you'll also gain some more power as it's a better turbo.

yeh those were the points behind buying it to be honest. just me being clueless old me, didnt take into account it would need mapping. watch this space. haha, cheers Devon

Saw your car ontop of town last week matey, so gathered you was up and running.

You may have heard mine screaming for mercy haha

What's already been said; get RS Tuning to adjust your map. You should make a bit more power out of a stock VNT17 as well

got it back saturday, but went out sunday, so must av been recent lol....come say hi next time dude

Think it was saturday night, you was parked just infront of the solicitors as you get to the top of the hill.

Kinda given up with the Octavia at the moment, the threads are stripped out of the head so the inlet is proper bodged on at the moment.

Plus the turbo blades dont look too healthy either, given that the turbo's only got 9k on it :(

Will come and say alright next time, probably wont be for long though. As im busy busy busy recently lol.

will av been sunday mate, saturday I was rather drunk haha, I was parked at side of a white corsa outside solicitors on sunday.

Oh dear, not sounding too good for the octy! how u manage to do that in 9k????????????

Can I ask a few noobie questions here:

What other engine mods have you done?

Can the PD130 engine take the bigger turbo OK without having to get uprated head gasket etc?

Lastly as advised a remap would sort your issue out - would these be the only two things needed for a PD150 upgrade?

it aint my subject particularly, but from what I gather, then engine internals and clutch etc are good for about 200bhp, after than you need the clutch doing, at around 210-220bhp I think your looking at injectors, oh and not forgetting a front mount intercooler, and to get the most from it a proper exhaust system.

Well thats my understanding anyway....

Or the engine internals are good for silly silly power (the yanks keep trying to blow up the block with no luck) the clutch isnt good for any BHP but a thing called torque, to which a standard clutch depending on wear and driving style can take 270-320lb.ft. So most people go with 300lb.ft as a base figure, this doesnt mean if you run 299lb.ft your clutch will work forever however. Standard injectors without any other fuel added are infact good for 220-240bhp generally speaking.

So basically, yes the PD130 engine can take the bigger turbo ok, without any other uprated engine work. A remap with a PD150 turbo alone would work fine on a PD130.

I thought clutches had power and torque limits? not just one of the other.

torque kills clutches not bhp

torque kills clutches not bhp

In this instance I know it bears no real relevance, its just for my own knowlege, but obviously our cars are really torquey, so as an example, say we get more bhp than we do torque, by a long shot. do we only need a clutch thats good enough for the torque rating, or mores the point, if i choke back the torque, what stopping me having a hybrid on a standard clutch?

Your answer is nothing. Other than common sense of course.

That'd be just silly. Why hybrid and not get all the gains.

On another note T Spark, my devils own kit is going in on Sunday so will let you know how it is. The tank is going in the boot too

for me the gains are power more so than torque...torque makes it feel quick, power actually makes it quick....so if i can get the benefits i want from it I would, but from whats been suggested that can't actually be done? or can it?

Whoa, think we're getting off-message here. Torque and 'power' are inextribacly linked. For example, horsepower:

Characteristically, a diesel engine produces more torque, but then it has to, to produce enough 'power', as the design and combustion limit of the fuel only allow it to operate over a small rev-range, compared with a petrol engine.

Put simply, you can't have one without the other. Think you're making it too complicated. Leave the rest of your car standard, and just adjust the mapping to suit the PD150 turbo, along with your std side-mount intercooler.

If you want high 'power' but no torque, you're with the wrong brand. Try a Honda garage and ask for a VTEC

(and no, that isn't a dig at them - I've had two, it's just horses for courses and what you want to get out of a car, and how you want it to drive and behave).

HTH,

Steve

LOL, thanks for the advice, I was just trying to get an answer! Which you have given me - so thank you.

But woah woah woah? Honda.....as good as they are, I like SOME torque, dont hondas have about 2.5ft/lbs haha

Sorry, might have got a bit carried away - apologies if my reply came across a little blunt

Seriously though, I hope that helps. You've made a good decision running with a stock VNT17 in there. Once it's mapped accordingly, you will notice a little more lag when it comes on boost as the compressor wheel is larger, but it will be worth it mid-range

As for the Honda reference; that was just for dramatic effect :P - the other side of the scale, so to speak! It also demonstrates a valid point though, that if you're prepared to work the engine, you can still get the performance and work from it, IF you're prepared to rev it. It's just balancing the top level of that equation - in a VTEC you have far less torque, but much more rotational speed at your disposal. The result? Still a decent amount of power

Cheers,

Steve

Im glad you see sense aswell, be like having the best striker in the world on your team, then saying he has to play with his boots tied (sp!?) together. Or what I like to personally call. Fail.

Nice one, are they fitting it for you? I might pull my finger out and fit mine too! Without going too off topic, what are the stats of your car so I get a good idea (if I havnt fitted it) what I might get mate.
