blow head gasket
no it wont. the blocks are different..
i have a 91 eagle talon tsi fwd . iv had the car to 160 but i would not advise it because the car gets extremely light.
The eagle seized it in its talons and quickly tore it apart with its sharp beak.
fuel...
i would swap it with a 4g63 t
Needs a tune up?
vacuum leak.
bad ignition coil, bad ignitor
some one screwed up
From all the research I have done on the Talon I would say it should match up perfect. the 1990-1994 models are all the same. Your best bet would be to get the part, test fit it, and then install it.
Yes you Can... it is extremely easy! You would do it like you were putting the 92 engine back in it!!
Yes much trouble. The motor mounts are not the same as well as the axels. It would be easier for you to convert the 420a engine to a turbo modified. They make turbos kits for the 420a
