I've come across a very clean, relatively low milage (52k) 1980 Citation for sale near me. Not being familiar with the model, I've discovered they are widely regarded as one of the worst cars GM ever made. The upside is that it has the first gen 60* v6 and a TH125, a curb weight of 2450lbs, and the most important aspect for me, it is repairable by a shadetree mechanic, and has no electronics in it (EMP proof).
Having said that, the car has known issues involving torque steer, and the rear drum brakes failing/locking up.
It is affordable enough to be worth it to me to buy it and invest pretty serious money into it, let's say $3k in addition to the purchase price of $1.5k.
It is the X platform, which as far as I can tell is body on frame. It is also related to the later A platform and the Fiero's P platform.
I've been mulling some modernization while retaining the ability to drive without computer chips:
Upgrade braking system to 4 wheel disc, larger booster, alloy rims and lower profile tires
Reduce torque steer (how?)
somewhere between 180-200 RWHP
My questions are as follows:
Would the 3900 LX9 block drop in? I'd like to obtain a complete engine, lock the VVT at +10* advance, and drop it in stock, removing the upper intake manifold and replacing with a fabbed 4bbl dual plenum.
What options do I have to strengthen the TH125? I was considering installing a 4T60 with manual lock up, and maybe using the crank hall sensor or some other RPM signal as an automatic TCC defeat. As far as I can tell, this circuit can be designed without semiconductor components. Is this a direct drop in physically?
What options might I have to use performance-oriented suspension components from later derivative platform vehicles? Macpherson struts, coil-over suspension, etc.
Thank you for your time,
