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. |

96mm KB's for 66mm crank and move up to 1800S heads. I'd guess 90hp max. Headers would be a consideration, only true bolt on HP, but at your HP it won't be a huge improvement. Maybe 5%. No replacement for displacement, consider stepping up to 2,0, but no idea how well it would work with 1.7 djet. L-jet works for sure and 2,0 djet. I love the 2056 2.0 head Ljet combo. |

I do have a set of nos mahle 94mm P&C's. Also have a 2.0 crank. I don't know if either of these will fit or work to improve power. I was hoping to see 100 but I realize the stock 1.7 d-jet has limitations. Weight reduction (of the car) will also help to increase performance. |
