Engine change 700 1991

Wondering if anyone can help me I removed a 1991 b230ft engine and replaced it with a 1988 b230f engine now car starts if I keep the throttle down it will run but I hear. A popping noise and car will not idle I used all senors and distributor from the 1991 car any reason this shouldn’t work

Fuel pressure regulator is different between the turbo and n/a.

"A popping noise and car will not idle I used all senors and distributor from the 1991 car any reason this shouldn’t work"
-> Check your plug cable sequence at the distributor. Its easy to get mixed up between cylinders 1 and 2.

If you retain ECU, ICU, turbo exhaust, turbo injectors, sensors & other parts from your old engine, only use main mechanical parts from NA engine (engine block, upper cylinder) then this should generally work. You may have to swap the old turbo camshaft into the NA.


Amarin.

Pretty sure the turbos use a different ECU and injectors. No sure if that is your issue.
