What can I do to rebuild my 1.7 for more HP and torque but keep the original d-jet.
piston and cylinders crank camshaft heads ? I know I can't change the cam too much but is there one that will do better and still work with d-jet. I know there is modern FI but I'm not interested. No carbs. I'm not looking for all out HP or dropping 10K on an engine kit. I just want a nice bump in power, if possible, while keeping a stock looking engine. |

Stock 1.7L at 8.2:1 compression ratio was 80HP (72 1.7 was 72HP)
Stock USA 2.0L at 7.6:1 compression ratio was 95HP Stock Euro 2.0L at 8.0:1 compression ratio was 100HP So stock 2.0 Euro spec is a 20% increase over a stock 1.7L 80HP engine. Get rods to go with your 2.0 crank and pistons. D-jet will have no problem with that size engine, many run D-jet on 2056 engines. 73 2.0L D-jet used the same ECU as 72-73 1.7 D-jet but has different injectors, head temp sensor and MPS. Jim |
