Hi everyone! I’ve just introduced myself in the New Members section and thought I’d jump right in here. I currently own a 2006 Megane F1, and I’m looking to learn from the group and get some advice on a few mods/upgrades. The car still runs stock internals, and I don’t intend to push it beyond its safe limits—just aiming for a bit more performance, around the 200kW at the wheels mark. Current mods (done by the previous owner): Decat + downpipe (63mm) Mid-box delete Stage 1 tune (presumably from RS Tuning SA) I’ve recently acquired a complete RS250 turbo and plan to have it fully refurbished and balanced. Now, I’m weighing a few options and would appreciate your input: 1. Turbo Choice: Would it be better to: Hybridize my current 14T to something like a 16T, or Use the refurbished RS250 turbo as-is? Which would offer better performance per cost? And if I do hybridize, how large can I realistically go on the compressor wheel before it becomes inefficient or unreliable? 2. Intercooler Suitability: If I install the stock RS250 turbo, could I run the OEM intercooler for now? (The car won’t see track time—just the occasional spirited run.) 3. Upgraded Intercooler Options: If I go the hybrid route, I’d definitely upgrade the intercooler. Locally in SA, bolt-on options are limited, so I’d likely fit a universal bar-and-plate intercooler (600 x 300 x 76mm) with custom piping/fabrication. Would this be adequate for a hybrid turbo setup? 4. Remap Requirement: If I install the stock RS250 turbo, is a remap absolutely necessary right away? I understand I won’t get the full potential out of it without a tune, but will it still run reasonably well in the interim? Future planned mods: Full 76mm (3") exhaust system front to back Upgraded rear muffler Performance panel filter (retaining stock airbox) Any advice, suggestions, or shared experiences would be greatly appreciated. Thanks in advance!
