toomanytoys: Using a  1.9DG pierbug on a 2.1 DJ engine

If the truth be known.. it possibly would benefit from running some smaller jets. as the engine should give a bigger vacuum.. in reality the standard jets in a 2E3 work very well and give the same or better than DG mpg (I used to get same mpg but travelling faster) as the cam timing is longer so allows for the charge to get into the engine.

One thing with the DJ is you will have to consider what timing and fuel to use.. UL95 use 5 deg BTDC, or with UL98 you could go a bit higher maybe 8 deg BTDC but I would be a little wary of runnng 10 deg on UL98.. the Fi has better control over the fueling than a carb.. unless anyone has put a lot of miles on a "DJ'd" DG.. I have but on LPG which is a different kettle of fish..

Air filter.. if an early square type then dont worry, same as in Audi 5 cyl turbo's so flow plenty of air.. but I would make sure you rebiuld the carb before using it and set it up properly. If you can stretch to a rolling road session with someone that knows carbs, then you could fine tune the timing and carb settings/jets, but it will cost you.. but you would know whats going on..

Its a great conversion, lots of usefull torque, without compromising the mpg.. Oh and think about using the oil cooler from the DJ as the extra heat needs to go somewhere, plumb it in to the coolant return from the carb heating.. make sure the cooling system is in good nick and fit a new genuine thermostat (been some problems with some aftermarket ones.)
