Hello, it took me almost two month but finally finished. I've installed a 3SZ-VE (1500cc) from a Terios into the copen 1.3 chassis. Original engine was K3-VE (1300cc). Now the copen has a healty 107HP. Getting moving and accelerating faster! Driving fun really increased significantly. This modification is not an easy swap. New engine block has an almost identical cast iron base, but it's height is + 2.5cm. Valve ports are bigger also, so better performance. A list of adjustments: Servo pump bracket from other origin Airco compressor bracket alu from other origin Calatysator bracket 1.3 + mm Coupling 1.5 Terios Coupling cable 1.3 +mm Coupling lever/cable Carter + oil pump suction 1.3 Distribution chain cover 1.5 Pulleys 1.3 Flywheel 1.3 Alternator belt tensioner from other car Thermostat housing 1.3 Oil filter housing 1.3 Motor supports 1.3 Transmission 1.3 Subframe lowered 10mm to be ablo to close the hood Front spring + 8mm, kidney flange to compensate Mini Rims Front spring + 6mm, piston under bearing to compensate lowered subframe Exhaust and cataliser 1.3 fits. Exhaust bushing +20mm to compensate higher engine block Air intake YRV turbo, this fits 1.5 trottle valve K&N air filter + housing (surplus) Engine bay cables 1.3 All sensors 1.3 ECU (+ABS!) 1.3 Cooling water hoses 180° and 90° new silicone Fluel pressure regulator 1.3 Oil filling cap 1.3 because it is lower Next step: chiptuning.
Hi @jcuyckens, how did the swap experience and reliability went for you until now? I'm interested in trying this new chapter for my 1300cc Copen, after I already have done a brakes front and back upgrade, a full intake with Sparco HP160, aftermarket exhaust manifolds from MaxRacing and a full straight pipe exhaust system, with a touchup with a chiptuning chip made by me for the airflow temperature sensor, and so far the difference is very noticeable. But I haven't yet pulled the trigger on the new engine because there are no others around talking about that other than you, so I'd think asking that after some years is a good way to let us know if it's all smooth and well or problems have risen for example the clutch or the gearbox in general Thanks for your time!
