title sais it all but.

i just took my ls turbo out of my eg cuz i hit a gard rail and there is no front end on the eg anymore and now put the ls turbo motor in my ek all i changed was my intercooler and my ramhorn and exhaust still using my obd1 hand command ecu but the car starts and runs very harsh and bogggy.

 

if you changed to a different manifold i would imagine you would need to
assuming you had a log manifold before going to the ramhorn

 

If it starts and runs like crap, why wouldnt you retune it..? Also, if you changed anything, it needs to be retuned. It may not require much time on the dyno, but it still needs some work

 

I think you knew the answer to that question before you asked.

 

It sounds like something else is wrong as well... Changing those few things *shouldn't* cause the starting to have greatly changed. I would assUme you did something wrong on the install/swap.

 

just check afr if its fine than it should be good

 

Might wana check spark plugs and or your fuel is the wrong oct. I know when I changed exhaust and ram horn my car never acted like that. But I still had it retuned cause I was running rich.

 

Fuel Pump in the new car the same as the old? Didn't see you mention that being changed in the post.

 

Thanks for all the help guys and well I used to have a bigger ram horn and a bigger intercooler and I never thought about gas ill try to figure out what's in there and yes still useing a walbro 255 just like b4. getting tuned today at 9am ill update after
