Yes you are able to increase the size of the turbo for more boost. If I remember correctly the turbo from an Alfa 2.4 JTD can be used but requires some modification and a remap.

I'll post more info if I can find it again.

Edit.
A MAP sensor capable of more than 3 bar
GT2256V turbo(I think)
bigger injectors
decat
remap
All required when fitting a larger turbo(GT2256V for example)

first, have you got a jtd 16v or a jtdm 16v. the jtdm has a better turbo to start with as it has a slightly larger vnt mechanism than the early 16v jtds(i think 5.5mm compared to 6.3mm if i remember)i have a jtdm turbo i have hybridised myself to somewhere between a gt1752v and a gt2052v but probably wont get on the car now till next year, it will be plug and play.if going through the hassel of modding downpipe flanges anyway id go gtb2056vk as this appears to be the hot turbo for around 2l cars at the moment.heres a link to alfa turbo stuffhttp://www.alfaowner.com/Forum/tuning-and-upgrades/294692-project-147-jtdm16v-gtb.htmlhttp://www.alfaowner.com/Forum/tuning-and-upgrades/252957-8v-jtd-turbo-upgrade-200-210hp-159-turbo.html http://www.alfaowner.com/Forum/tuning-and-upgrades/190996-147-jtd-turbo-upgrade-options.htmlheres a link to a guy that mods them to vacuum actuators from electronichttp://www.darksidedevelopments.co.uk/products/darkside-gtb-turbo-kit-for-1-9-8v-tdi-golf-mk2-mk3-and-mk4-platform.html try tdiforum and search gtb2056vklook here for ryanp and search his posts on the gtb turbos.regarding injectors the jtd 16v and jtdm are similar in flow i think but the jtdm ducati corse from alfa gt have more flow i believe but are hard to find and the jtdm will flow enough for 260hp.1.9 16V 110kW CR-IPL17-ZEREK20S Bosch 0 445 110 2431.9 16V 125kW CR-IPL17-ZEREK20S Bosch 0 445 110 341hope this helps

i have a 2007 croma, manual dont tell me what engine is in it, its looking like i maybe have to strip half the front of the car off to see if a noise i have is the turbo, if it comes down to having to do that, i was wondering if there would be a cheap other turbo to put on
 
Il post part number up later for the latest turbo,I think it's 777250-1 this replaces all 16v jtd turbos.i got mine off eBay from a Alfa gt q2.
If you can be off road,you could let a turbo specialist rebuild and fit a 52mm comp wheel but £450-650.
What's your noise ? Siren ?

260bhp
Is that really possible from a 1.9 JTDm?
What other mods are required apart from the Turbo?
 
Yeh I think so, just a fuel cooler. I know some cars have them std my fathers Fabia vrs had one under the drivers seat under the car to cool returning fuel on its way back to tank. I think it can warm up a fair bit in injector back flow, fuel rail and high pressure pump.
Here's something

On the 16v thee is a fuel temp sensor in the bottom of the fuel filter so I'd fit cooler in return to tank or before filter on supply, then the ecu should adapt as necessary to cooler fuel.

Not speaking from pure fact here but it could be that during cold weather, diesel freezing can be common and maybe this is to negate that. Not sure how that would help if the diesel lines from the tank were frozen though. :confused:
 
i wouldn't bother getting a different turbo from another car when you can have you existing one bored out and different sized impellors.

I spoke to a company recently i think it was CT Turbo's and they quoted me about 600 for the work. a lot less hassle than making another turbo fit.
 
regarding fuel temperature, i think its only the higher temperature that is wanted to avoid for high power target outputs.picked these figures out of a thread on diesel density vs temp15 °C, 921.38 kg/m³ 25 °C, 914.47 kg/m³35 °C, 907.54 kg/m³45 °C, 900.57 kg/m³55 °C, 893.58 kg/m³65 °C, 886.57 kg/m³at a guess?if the fuel is too hot more is needed at a lower density to acheive an equal total amount.on highly tuned diesels the injection window may be maxed out at 65*c, cooling it to 15*c may gain 4% total fuel amount.or cooling the fuel and reducing injection window by 4% may equal same power using less fuel,more effecient with less egt and less pcp.i wonder how much the diesel lubricity changes with temps?
