If bravo tjet was too high insurance shouldve got a gp tjet, ins group 6 and will map to 150 bhp.. As for a turbo conversion, warranty will be voided. Tyres, brakes, suspension wont be up to it. Turbo requires low comp, stronger internals, stronger clutch possibly stronger gearbox and driveshafts. Engine will probably need an extra injector on a auxilary ecu to provide the turbo with the fuel it needs to match the air itl pull in. Turboing also takes completely different exhaust manifold system because it works off exhaust gasses. The tjet turbo kit wouldnt just bolt on. Just because they both say 1.4 doesnt mean theyre the same but one has a turbo. I could go on but i wont waste anyones time. You can do it...but with thousands of pounds put in and mechanical experience which you seem to lack. Even if done its likely you wouldnt get insured..or itd be a fortune. Itd probably de value the car too. Youd have a good £4000+ in it more than you could sell it for. Its a nice thought but best kept as one. Low pressure supercharging would be easier but not easy. Or cheap. The engine isnt made for it. Nor is any of the electrics, which are a can of worms. Again superchargers produce torque from low down because they run from a belt and dont need to spool up, so again...gearbox and shafts plus engines innards under strain. Basically all the same issues as the turboing. Just slightly less complicated...for someone mechanically minded. Regardless of wether itd be a diy job or done by professionals itl cost ridiculous amounts and give no dividends and the motor wont be strong enough in n/a internals to handle boost to make enough power to justify the cost. If u arent mechanically minded and want to do it yourself - no chance. If u are mechanically minded but dont have the money - no chance. If u have the money - buy/part ex for the car you want. Or wait for a year or so. Gp tjet really is the obvious option. Dont wanna shoot down your ideas mate but its a minefield.
