Does the turbo from the multiair (t-jet 1.4) fit the twinair (85 ps.) motor?

Has anyone done this modification?
 
I don't know if it would but why would you want to?

Simply changing the turbo won't do anything for performance. You need more fuel and boost and possibly cooling. Forcing more air in there only doesn't work.

Start with a re-map and maybe a larger intercooler. I think it's reasonably easy to get circa 120+bhp.
 
The boost comes from the turbo and the turbo on the Twin air are no good for more than 105 ps (to small). Injectors are 435 cc and should give 140-150 ps.

A large intercooler and the turbo from the multiair (where it can provide boost up to 200 ps) seems to be a relativ cheap way to get more power but don't know it the turbo would fit and what kind of modification is needed and how much boost the stock engine can take.
Is someone has experiance with this modifican it would be great :)
 
I have done some basic research and have to say that after a week with the TA 105...as a city car and little buzzing around car...105 seems plenty !
 
The turbo from the 105hp should fit the 85, swap out the intercooler (not sure if the 105 IC is the same), get a remap and you've got around 130hp. That's my plan.
 
130bhp sounds lovely! :)

I'd be very interested in watching you with this upgrade and how simple/difficult it would be ............. and the costs of course.

Thanks,
Mick.
 
I know the manifold is different and I think the EU6 has electronic boost control, neither are insurmountable problems. But I've seen TA engines with 30Kkm on them for $800 so that's likely the way I'll go. There will still be the issues of the electronic boost control as well as the electronic thermostat to deal with, so not really plug and play. In theory I'd also have to swap in the EU6 ECU and CAT to be legal.

For now UFI's traveled ~9000km from new and has a week of warranty left (not that Fiat warranty is worth anything), and Australia has yet to bring in any TA105 models. But at $800 each I could see myself stock piling some 105hp's and dry storing my original, that way it I could turn up the wick on the 105's and it won't matter really if they only last 10,000km each.

I'm not sure I understand. The Euro 6 also has a different cylinder head than the Euro 5. Would you swap that too???
 
You're right, I forgot the head and manifold are one on the EU6's. Can you confirm that the IC is different?

The 105's turbo is a Mitsubishi TD025, same basic unit as used in various small diesels. It's available with either electronic or vacuum controlled waste gates.

The stock cast manifold really needs to go as it's heavy and restrictive. It's hard to save weight from the front of a 500 (any car really) so an improved manifold (Ti perhaps) would be the way to go.

Back when I had a Honda City Turbo the hot ticket was a turbo swap for a Mitsubishi TD unit ;)

But to get back to the original question, for a standard road car, the Abarth turbo is the wrong place to look for a TA upgrade, you'd have far too much lag.

I'll be interested as well how you go with any upgrades..

According to ePER (v84) the TA85 shares the cooler with the 95 hp diesel engine. The TA105 has a different cooler, but I don't what the difference is.

Do you really mean the wastegate? I know these turbochargers are available with either electronically or pneumatically controlled dump valve. A dump valve isn't a wastegate though.

Thanks for looking up the IC specs. Yes, I mean dump valve.

Thinking about it, I think I want to have covered at least 18K km before I do any engine related mods.
