How to tune a Renault Laguna 2.0T 163hp

[s_o_n_y]

Hi everyone, i found a cheap Laguna 2 2003 2.0T 163hp that i need help with some questions.

they said that they have the old Sagem 2000 system in this cars and the newer Sagem 3000 in 2005-2007 170hp. And the old Sagem 2000 system is hard to remap.

My questions is then: Can you remap the old S2000 with some Renault RS Parts bolt on and get like Megane RS performance ? If not..
Can you take a Reseted Self learning PnP ECU Sagem 3000 and mount it on the older Sagem 2000 cable harness and just start it ? If Yes, then i have a much easier OBD2 Tuning that i can use to Remap it.

Thank you in advance

If you dont have the answer, is there somewhere else i can turn this question to ?
Im in the middle of spending money on this Laguna PH1 instead of buying a -05 PH2. I dont wanna because they dont look as good as the PH1

I have no idea i'm afraid, but the power differences wont just be the ECU, it will likely be in the head and camshaft too.

 

[s_o_n_y]

Ofcourse, im fully aware of engine parts that i have to swap out, like Turbo, Cams, injectors and so on. The thing i want to know is if the S2000 ECU can be remapped for this kind of changes. I dont want to change all the ecu harness just to get the S3000 ECU system. Or is it any other Plug n Play ECU boxes on the market like Megasquirt ?

I really like the Laguna 2 PH1 look instead of the PH2 from 2005-2007.

It's far from easy as it can't be remapped via obd. Just google for example "How to flash sagem s2000".

 

[s_o_n_y]

Yes i saw that. I just wondering if i can map it later with some new RS parts

 

[s_o_n_y]

Does anyone know the type of flange on the manifold ? T3 ? T25 ?

 

[Adey]

its a renault/td04 flange on there same as the megane 225 as far as i am aware

[s_o_n_y]

Thank you !
Hmm, think its cheaper to by a manifold with T25 flange and a turbo the find a Uprated turbo with that flange :/

 

[Adey]

why not just buy a second hand 225 turbo they are super cheap? direct fit and good for 270bhp and a 250rs turbo will nudge over 300bhp.

i think your engine may be higher comp than the bigger stuff though so may cause you issues. definitely has different pistons to the 225 last time i checked.

 

[s_o_n_y]

My problem is that you cant by these engines in sweden cheap..and i cant find anyone send a engine up here

 

[Adey]

why do you want a whole engine?

 

[s_o_n_y]

Ahh oh sorry, you mean only the turbo ?
Where can i find one of these ?

You are after the manifold and turbo. For reference the turbo is a TD04-14T from the 225/R26 and the slightly larger 15T from the 250/265/275

 

[s_o_n_y]

Thank you Andy for that.
Do i need the manifold aswell or does mine 163hp fit ?

I *think* yours manifold will suffice as IIRC its a 10T turbo.

 

[s_o_n_y]

Ok, then i buy both manifold and turbo. Thank you so much for help. Much appreciated

No, you do not need another manifold. It's the very same in yours than in Megane II F4Rt or Megane III F4Rt or Laguna II/III F4Rt. You just need that bigger turbo. TD04-14T can be taken from the F4R-774 (Meg II RS), F4R-784 (Lag II GT), F4R800/802 (Lag III GT), and TD04-15T from the F4R-874 (Meg III RS & GT220).

At least one TD04-14T (F4R-774) seems to be for sale in bildelsbasen.se, but that one is overpriced (5.000 SEK).

Pretty much the same price, but this one from Lag III GT is a bit more reasonable as its mileage is only 50t. Ok, still a bit overpriced, but... you just have to negotiate a lower price .

Anyhow, as mentioned earlier you cannot tune it too much because of partly different internals and higher compression ratio (9.5/1) compared to TD04-14T engines (9.0/1) or TD04-15T engines (8.5/1).
