I've been kicking around what to do with the stock 1.7L, w/single progressive carb engine that came with the car that I've been messing with lately. Car's not been started since I got it, though I did hit the starter a couple of times and it sounded promising (dirty old fuel, tank, carb and fuel lines need attention). Anyway, I don't want to keep the single progressive carb for very long and was thinking of eventually getting dual webers or repros. But I've been offered an L-jet system from a 1.8L, for a good price and had some questions.

-Will it work with the stock 1.7L distributor?

-I've heard that it might run rich on a 1.7, and this offer does not include injectors - would just going with a set of stock 1.7 injectors eliminate that tendency and be the best bet?

-Also, I've had a brand new set of 96mm P/C's for 1.7 case in storage for a few years now.. I guess I could slap those on while I have the engine out for some engine bay touch up. Like I've mentioned in another thread, I hope to not have to split the case tbh. Would you guys bother and would this change which distributor and injectors you'd go with?

The L jet and D jet parts don't interchange. The Djet is fired from the distributor and the L jet is not. you could run a 1.7/1.9 on either induction system, but think you need all of the components for that system to match (computer, distributor, mps, or flapper box)
