bigger turbo...

will be needing a bigger turbo to run with the repmap/intake/decat/clutch.

ive sourced a couple of parts from companies online and garages near me but i think i need one of these...

GTB2260VK. can anyone get me one for a decent price or recommend something similar/bigger?

just in case... its the 1.9SE TDI

thanks people

Problem with the diesel id recomend asking on tdisport.com, They know what they are doing and willl recommend the perfect kit for you mate!

Pikey Calorgas - NOS conversion FTW!

You might be nearing the point I heading for, where I think I want more power, has the other stuff been done yet and you still feel it is not enough?
It will still be two wheel drive, make it deliver the power it has and be able to handle that and then see if you have a usable ride. Have you changed the diff?

We should meet up for some chatting and fun, I hope to make the next meet if work permits.

that would be really good cali.. i havent had anything done to the car but because of my issue with insurance. The upside of this is that im saving well over £££ a month.

Im currently speaking to allardturbosport.co.uk about a 'hybrid' turbo - they have given me a turn around time for about 10 days and explained I could get about 230bhp from it. There are other ways I could go instead of a hybrid such as a new, bigger turbo, but obviously thats more cash I would rather not spend.I have also had several quotes for a larger intercooler with a silicone pipe kit to fit it... with my rather ass knowledge of how cars work im going with the basics of deiesel:
(more fuel injected + more air + big turbo = fun)
my issue at the moment is that when upgrading the turbo to a larger kit or a hybrid what other components will need upgrading?

Well the the coillies, so should handle abit better, the standerd set up of the rest should be albe to handle the extra power, any more than that wouls start causing issues tho.

At 230hp and the weight of a Mk5... I'd be thinking about bigger brakes first! As well as decent tyres that can handle the Torques" you be putting through them... then drivetrain... gearbox is "probably" ok but what about CV joints and driveshafts?

Your logic is sound but there is always a but.

Regular turbo diesels are designed with decent mid-range ooomph in mind - thus why the turbo is normally the first thing to hold things back. Small turbo is easy to spin up and will boost up nice and early but then run out of blow as the revs rise. This is why tdis are very quick mid range and then feel like they aren't gaining anything when rev'd...

So, as you say you want more power so you need more fuel and a large flow turbo. A larger turbo will take more energy to get to boost up therefore more lag but will provide the stronger top end you seek. Also, your car almost certainly has a variable vein turbo in it is order to get around the majority of the lag issues... getting a larger but traditional static turbo will lose you that also. Worst case scenario in your bid for 250hp+ is that you go from a car that boosts strongly from 1500rpm to one that needs 2000rpm+ or maybe even 2500rpm+ to make good boost. Without a doubt you'd make good PEAK power but you'll have lost a lot of the general drivability of the car.

Another consideration is your injectors - they have a fixed capacity also. Larger injectors are more expensive and less accurate so factory built cars come with injectors matched fairly closely to the cars requirements. Most cars injectors will top out at 25% more power than stock. FYI, modern VW TDIs such as yours use enormous pressure injectors that are very very expensive... off the top of my head you can expect to pay £300 EACH for a new set of slightly larger ones.

It sounds like you are reaching the limits of the stock components... you need to be very careful where you go from now on.
There is no such thing as a performance increase with no tradeoffs in other areas.

EDIT: I just looked up your car and you have one of the rubbish old diesel engines so you have a normal static turbo and your injectors aren't insanely expensive. The above is still valid though.

rubbish old diesel engine? ..... that hurts

Ive got the AFN 1.9 tdi 97 a4.

ive change the nozzles on the injectors to .216's instead of the .205's and a straight through system no cat no box's, and a panel filter, feels 100x much better and its cost me what roughly around £300 in total, ive gain a good bit of torque and bhp, playing with gti's all day long .

Cant wait to get my turbo, int.cooler, clutch, and map.....COME ONNN!!!

can you please pm me your number dude, would like to speak to you about it! im interested in doing something similar and if your in the know etc etc....

Sorry, no offense intended! I've got a rubbish '93 engine in mine

PD diesels are vastly more tunable than the "classic" diesels... I just saw your sig pic of a mk5 and instantly assumed shiney new PD... I wasn't aware they still put the old diesels in such a new car. I guess it's for exactly what I was talking about... avoiding another £1500-2000 worth of parts to keep the costs down on the lower models.

At least you can tune yours more cheaply!

Big turbo, big intercooler, bigger injectors - the skies the limit! Just be aware of the tradeoffs The trouble with starting with a lesser engine is that you risk very quickly spending more on your car to get 200hp than selling up and buying a GTD, which is better in more areas than just the engine, would cost.

only messing about buddy

....i thought my car had PD injectors...
it is a 56plate 1.9 tdi se model.... what injectors do i have?

if i dont have PD and i have the earlier model injectors that means i can upgrade them from the standard 205's ...horray! more tuning fun
