Hello! I am new to this forum and as it appears, it must be the biggest renault dedicated forum, at least for modifications. I am here because i want to modify my renault laguna 3 GT (2008) with the 2.0dci M9R engine, 178hp. I know this is a megane forum but the engine exists on the meganes too. It already has a stage 1 map and a downpipe added, making around 220hp. Tho, i want more from it, so what can i do to it to squize more power from it? What are your thoughts on these?: 1. Hybrid turbo - this is probably the easiest upgrade but not the most cost efficient because it wont be a significant up in horsepower (max 250hp) and i heard that the turbo wont last too long. 2. Bigger intercooler - as it is now, the stock one i heard that it is good for 260hp, and there is not anything off the shelf upgrade. You must do some work to get it on. 3. Bigger injectors - there isnt a bolt-on option neither, at least as far as i know off 4. More agressive cam profile and stronger engine parts. Sorry if i posted in the wrong forum section and for my english too, not from around here. Thanks.
I don't think you need to worry about stronger internals Pic is of a DCi 175 Megane conrod and piston (on the left) and the other is an R26/225 rod and piston. https://flic.kr/p/2nPxnvv And her is my air filter you asked about https://flic.kr/p/2nPyX1h
