Fellas,

Just put an FG2 Turbo motor into a BA and fired it up and it's running what seems a bit rough

Only started it and ran it for about 30 seconds before I had to go out, it sounds like it's got a lumpy cam and was idling at about 1100 opposed to the usual 1000 - things that I can think of at the moment are a bodgy vac line I had to do and sealed with gasket maker on the barb at the manifold (plastic fitting with the 8mm and 6mm barbs on one) or the injector plugs that had the permanent marker rub off a few.

Any suggestions where else to look when I get back?

Idle should be 750 not like 1000

Is it using the fg ecu or ba ecu, just thinking if you are running the ba ecu it may just need a tune. Im no expert just a thought

Edit: If you only ran it for 30 seconds it could just be cold idle rpm, otherwise possibly thermo. Also make sure fuel is good.

How are you running the FG motors cam phasers with a BA ecu?

Sorry should have pointed out it was cold start. I let it run till warm and it seemed normal apart from the exhaust sounding a little lumpier, although I know they have different cams but I wouldn't expect that much difference hence why I was/am worried!

The motor had been fitted to a BA previously so I'm not sure about the phasers to be honest

It is the BA computer and was tuned (not for the motor I've put in) - going in for a retune ASAP but think I'll trailer it there instead of babying it.

Ba pcm will run an f2f motor. Won't have individually variable cam timing(unless ba fpv pcm) but will happily control cams otherwise.

 

Op did the fg motor come with injectors?

Nope, still using my BA injectors on a FG rail/intake with spacers

If the cars running fg intake/head/cams it will need at a minimum the airflow tables in the tune touched up.

What's everyone's opinion on driving it a short distance? Either 5ks or 15ish

it'll either fuck it or it'll be fine.

 

Hard to say from here.
