I had another topic going regarding my plan to build a 2056 from a spare 1.8 motor. Initially, I wanted to find out what was necessary to make my existing D-jet on my running 1.7 work with the future motor.
I learned that I need quite a few 2.0 D-jet components to make it work...and then from what I understand in reading Jake Raby's data on the 2056, I'll still max out at around 115 hp with the FI. So if I were to revitalize the L-jet system from my spare car instead (a 1975 1.8), would it be possible to get the 120-125 hp a carb'd 2056 makes? What tweaks exactly will be required to make the L-jet perform safely, and correctly? I have read that the fuel pressure may need to be raised. What are the other considerations and can they be handled by a competent DYI-er? |

Hello Everyone
Asking for some advice. I have a 74 1.8 L-jet running fine. Recently obtained a same year 2056 in a 1.8 case. Raby balanced, stock cam, hoffman heads. Wanted to transfer components from my existing engine to the 2056 and pray it works. Any advice? Would keeping my current injectors be ok or need to upgrade? Any more current advice or experience, as this thread is 10 years old, but probably remains relevant. Thank you for your input. |

Any more current advice or experience, as this thread is 10 years old, but probably remains relevant. Thank you for your input. You will need bigger injectors... buy 4 injectors for a 1980 Datsun 280ZX. They have the right flow for this. I would also suggest that you do the bus throttle body mod you can find on here. The stock 1.8L Throttle body is a bit small for a 2056. You will also need the 2.0 intake runners. The intake ports and head stud pattern are different between 2.0 Heads and 1.8 heads. The 2.0 runners are a bit shorter, but you can use longer hoses between the runners and the intake plenum. Good luck!. (IMG:style_emoticons/default/welcome.png) Clay |
