I've tried searching this and looking for tech articles but haven't had much luck. Sorry if this has been covered already.
I have a 1.7 with functioning factory FI. I have a parts 1.8 which I plan to build into a 2056. If I wish to run the larger motor with D-jet, what FI components of mine can be retained....and what exactly am I going to have to source to make the system work with the larger displacement?
I'd like to start collecting parts as I come across them.
Thanks!
From your 1.7L you can use the fuel pump, fuel pressure regulator, injector manifolds, ECU brackets, tri-spade ground lug, trigger points, maybe the TS1 and thermoswitch, thats all.
Otherwise you will need a complete 2.0L injection system from a 2.0L, including the intake air hardware parts and ignition/FI harnesses.
1.7 injection will run a 2.0 when used with green injectors. I have done this. the rpm will top out at 5000
Thanks for the replies.
I did check out the Anders site and it was very informative.
Another question: In one of my searches, I read that the L-jet is good to 160 hp or so and is fine on 1900 and 2056 conversions with a little tweaking.
Since my plan is to build the 2056 from my parts car's 1.8, would I be better off going with L-jet since I already have a complete system for that as well? ....I mean, presuming umpteen years of sitting in the elements hasn't ruined most of it?
yes!...just restore all the Ljet parts, clean up the AFM and check it with the manuals to make sure its good. Send the injectors out for cleaning and clean up the wiring.
no dripping. why would they drip? what does that mean?
it just ran out of air. AFR was OK. WOT enrichment was enough till it ran out of air. it was rich till about 3500 or so. I wish I had saved the data log.
I think he is saying it would run lean but not with the green 2.0L injectors. As you say it will run out of air with the small runners and plenum before going to lean. Porsche figured this out in 1972 with the first 2.0L engine after VW said it couldn't be built.
