how would you upgade the 170cr turbo.turn it into a hybrid or is there a bolt on upgrade

What sort of power outputs are you looking for , i think i am right in saying the std turbo is good for 235bhp with the appropiate map and exhaust mods

If it's significantly more power that you're after you'd be better off trading up to the tsi vrs as stage 1 remap will give around 260bhp. You'd need to spend a fortune on the diesel vrs to get anywhere near that. I've no idea what a bigger turbo would give you but it wouldn't be cheap. A stage 1 on the diesel vrs is the most realistic and cost effective way to get reasonable power gains but from experience it will just about put it on par with a petrol vrs standard.

IMHO, in the real world the amount of torque is more important than outright BHP!!

Petrol VRS has197bhp / 207 lb-ft

Diesel VRS has 167 bhp / 225 lb-ft

So arguably both are pretty close but even a pikey £400 REVO remap on the diesel will give you in the region of 205bhp / 310lb-ft and that does provide a serious amount of shove on the daily commute!

The bhp and torque figures might be similar (although don't underestimate the difference an extra 30bhp makes) but quite simply the petrol vrs is the quicker car. Also those figures don't consider power to weight ratio and I'm fairly certain the diesel will be heavier.

I have owned a tfsi vrs, a cr vrs standard and then remapped, and a tsi vrs standard (for one day) and then remapped, and I like I've said previously in my opinion the performance of the standard cr is a little lack-luster and the tfsi / tsi are the quicker cars. A remapped cr delivers similar levels of performance to a standard tfsi / tsi but a remapped tsi would destroy a remapped cr, no question.

I drive a remapped CR & agree with Jonno as above, with one proviso: the extra torque makes the diesel far more flexible, especially at low revs & overtaking, i.e. less need to change gear, although you will obviously run out of revs sooner!

In short, in a side by side drag race, the TSI will pull away & disappear, but try and lose a CR on a normal road in a TSI and you'll have quite a job.

Regarding a bigger turbo, your injectors will need upgrading to suit, along with remap, fuel pump etc., etc.,-not worth the money or hassle IMO.

A good remap & DPF removal is the most cost effective route to more power. jcdub on here has done this with his CR & it puts out 215BHP & 330ft/lbs IIRC on the dyno, with a smooth, non-smoky map. More outright power is available with a more 'peaky' map, but his car is about spot on.

Not sure I agree, the tsi isn't short on torque either remember and by using the gears I think the tsi would still be the quickest, assuming equal driver skill.

Granted, but what I meant was that in day to day driving on public roads, as against on a track, there would be little between them realistically. Sure, pulling away from a roundabout for instance, the TSI would pull away, but the gap wouldn't be like that between a 1.6TDI and a 1.8TSI (where's lol? :p) when it comes to keeping up/overtaking etc.

I was initially disapointed with the TSI vRS, after coming from a mapped diesel, I was frustrated with the lack of torque.

Had it mapped to stage 1, et voila problem solved.

approx 260bhp and 280lb, it pulls with diesel-like torque and then carries on where a diesel normally gives up at 4.5k.

No more changing down the gears when overtaking anymore.

Granted its not 330lb, but trade off is 260bhp. swings and roundabouts........

Yep and your MPG sir?...and be honest!

My mate has a stage 1 TSI and after a particularly bruising thrash back from London AVERAGED 22!!! Sorry but I'll take my oil burner and 44MPG anyday!

Seriously, I have absolutely no doubt that in a one-on-one drag race the TSI would leave the CR for dead but personally I'm not in the drag racing game and I doubt very much if Mr TSI could get away from me or any other CR on a normal road / cross country.

Anyway thats not the argument, I only pointed out that torque is, IMHO a much more important measure of point to point ie: real world driving performance than outright BHP

My mpg in my tsi vrs stage 1 is 29 and it was 36 in my diesel vrs although I'm not really interested in that to be honest.

I know which one is quickest point to point and which is more fun and desirable to drive and its,not the diesel. Don't kid yourself about it being able to keep with a tsi, I know from experience of trying to stay with a standard Leon FR on country roads in a remapped cr. I Just about managed it but it was seriously hard work. The cr is a good engine and if you're more bothered about mpg than performance its a great engine in the vrs but it wasn't for me, I couldn't wait to change back to petrol.

I think th OP wants information on tuning his diesel vrs. I dont think he wants to know about how fast the Tsi is with a remap/and should swap.

Thank you Tim!

Jonno, are you lol's twin brother by any chance? :p

I would suggest that a Hybrid turbo should work well, although the limiting factor may be your injectors.

thanks guys.seemed to get a bit off topic.it was the turbo upgrade i was interested in.not the mapping or changing to a petrol.

my turbo may need a rebuild so i was thinking of upgradeing in some way.

Hybrid would be good, but you'd still need a remap to make use of it? Incidentally, what miles are on your CR? Haven't heard of many going....

Wardy is running a hybrid on his PD-might be worth a PM? A brother of mine has a hybrid on a PD VRS-it's quick, but whistles like a deranged fire engine!

dpf has been removed and mapped.the figures off vagcom suggest the turbo is down somewherea long the line.it maybe the airmass meter or it could be the actuator sticking.

lowdown power is down.power coming in around 3k.then it goes like stink.

just preparing for the worst

You will need a custom map to make use of a hybrid

Haven't heard of any hybrid units for the CR170. Maybe worth making an enquiry with Turbo Dynamics, and a few others - to see what they could offer.

But yes, as you say if you reckon yours might be on the way out, there's the possibility it could be built back up with a stronger compressor wheel etc. On a CR would this not be a warranty issue though, or have you got quite an early example?

As mentioned before though, injectors might well be an issue. I have a feeling that they might need upgrading at any much beyond stage-1 power.

I think th OP wants information on tuning his diesel vrs. I dont think he wants to know about how fast the Tsi is with a remap/and should swap.

Even if the OP was about seats or radio someone would be on saying. "Yeah but the ones in the TSI as so much better"

When i spoke to Turbo Dynamics about a Hybrid on my Stage 2 PD170 They said there was no point really in Hybriding the PD170 Turbo, They said id be better of spending money on a bigger turbo.

They said a Hybrid would offer a bit more power and would ease the pressure on the current turbo but value for money wasnt much

True enough, good points. Perhaps as the CR170 turbo is already pushing the limits of that housing, and using a pretty reasonable size of compressor wheel?

Yeah, you could perhaps run a hybrid in a slightly more 'relaxed' state, but it's hardly going to offer the increase that you get, say from attaching a hybrid to a PD130

Yeh thats my understanding

You too right there lol, on normal bends/roads the CR can keep up easily.. too many people underestimating the CR cuz it’s a diesel, but diesels are the ones that are taking over on YouTube now
