will the lda off my TD IP fit on to my N/A IP with a altitude compensator? Top swap?
theres more to it than a top swap.
n/a pump has a fuel limiter pin in the side of the case that needs to be removed, or pushed out of the way.. otherwise you get no gains.
if you just do the pump top swap, then you gain nothing.. the limiter pin is still in place, so just before the LDA wants to engage, the throttle arm hits the limiter pin, and goes no further.. the TD pump DOES NOT have this pin..
but, had you searched a little, you would have already known this, and how to correct it, because this EXACT topic has been gone over HUNDREDS of times..
