I don't know if this is right area to ask...there is no area for Laguna GT...hmmm...
Anyway...
I am planning to change bigger IC and bigger turbo to my Laguna (Laguna II ph2, 2.0T)...do you guys have any idea which parts might be suitable?

Sorry mate, no idea, guess the laguna turbo uses the twin scroll unit TD04? Same as the megane F4RT?
pop some pictures up of the engine etc and lets have a look.
Ok. I try to get some pictures soon... :)
Ok...here are some pictures from engine bay and turbo...
Uses a slightly diff turbo it uses a td04-10t as opposed to a td04-14t.
There is a guy in greece, who's running 350 bhp from his laguna gt, have a look on meganesport.net think his user name is drlaguna or drturbo somehting like that.
Thanks...I try to find him :)
They are little bit slow to activate accounts :crap:
Ok. Time to update. It seems that DRLagunaTurbo is very hard to reach. hopefully soon.
I called to local turbo dealer. According to their information TD04-10T turbo is for 167 bhp Laguna ("low pressure"). That Turbo is not able to reach safely 205 bhp, so they said that turbo in my car might be TD04-14T (similar to Renault Megane RS 2.0T), but they couldn't confirm that.
Their price to modify turbo is quite expensive (900€). Do you have somethin to offer for me as other possibility (buy turbo from UK etc).
Ok...now it is time to go further.
Where I can find bigger downpipe and free flow (also bigger) catalytic converter to my Laguna? Any ideas?
More questions...what kind of actuator I can use in original turbo? I heard that if original actuator from turbo is replaced then more pressure can be used in system...any ideas?
Engine is same as it is in Renault Megane RS...
Yes you could use a different actuator or adust the arm on the one you have, but the ecu on that car controls/regulates boost. You would need a remap to match the fueling to the increased boost pressure.Quote:

I am looking for decat to my car...seems to be quite hard to find. Any help or is there someone who is willing to do it for some price :D ;)
Also I am getting new IC (not sure if there are similar in Megane 225?)...when I find one.
Ok. I will share some information from tuning up F4Rt engine. I changed whole exhaust system (starting from turbo). I placed metallic freeflow catalytic converter under the car and replaced old exhaust pipes with 2,5" exhaust system (I will post pictures later).
DP is now 3" and rest of the pipes are 2.5". All silencers are "free flow".
What I got?
Original bhp: 204 and torque: 310 nm
After exhaust system replacement: 227 bhp and 340 nm.
Fuel consumption when driving 100 km/h was earlier 7.6 ltr/100km and now it is 6,5-6,5 ltr/100km .
Whole system is custom made (no ready made exhaust to Renault Laguna 2 Turbo). Total cost of project (including EU-approved racing catalytic converter) 750 euros.
what about the megane turbo's? there a vnt arent they?
Have you got any photos of the new exhaust system? :)
Meganes turbos are: TD04-14T, no vnt.
I have pictures that I will post later then. :)
