*cough*
Yes, I still have this car, and yes, it's still eluding me as to what it deserves. That's why I've done precisely NOTHING to it so far.
The 123GT is going to require several years of labour and money, and this 780 is just sitting here, mocking me. I think I need to do something about it, so I'm considering pushing the GT out into the back yard for at least the first part of the winter and bringing the 780 indoors to work on it. It needs some stuff taken care of - some various rattles and squeaks, a lack of radio antenna, and a stock-ish stereo installed. I'm in the process of refinishing the Berturbo 15x7 wheels and mounting a set of tires I got from Alex. That's the bare minimum for the car to be sold, but I think I'm going to drive it for a few years.
In order for me to drive it much longer, I need to sort out the odd running issue: It runs very poorly when hot (down probably 20 hp, and the clutch fan locks up which drags the power down even more). It has that intermittent failure to run at all when it heat soaks in temperatures above 30* (not a problem this summer). It leaks oil and coolant, and it pressurizes the cooling system with compression to boot. The differential needs to be aimed at the engine a bit better (I built my own front bushing for it and got the alignment wrong).
Or, I can turf the V6 and put something else in. I currently have to choose from: (1) B18B (wouldn't that be funky?), (1) B23 bastard turbo, (1) B5234FT (high miles, lots of piston slap, still needs removing from Roberta's car), and could probably still put together (1) B300F (B280 V6 plus Eagle Premier parts).
(1) Is just stupid.
(2) Requires valve springs and reassembly, and would certainly require Megasquirt. Ignition & fuel systems would need sorting. I still have this T5 tranny that I could use, but I've sold the clutch so I need to deal with that. Needs a driveshaft and a pedal swap.
(3) As Roberta will be getting a newer car shortly, the 850T is available. The engine runs pretty well, but makes lots of piston slap when cold so I don't know how bad the bores are - I hear tell that they build ring ridge mighty quickly. With the liberal application of parts from a random 960, I could probably get it in there, mated to an automatic tranny, pretty easily. The electronics may not be as easy to sort out, though: I'm not sure if the 850 computer would drive the 960 tranny or not, but it may. Then again, the computer would have to be de-OBD'd to play nice with my '88, so monkeying may be necessary, or even a standalone and christ knows what the transmission requires. There may be a way to put a 5 speed behind the T5, though.
(4) Would require wrenching and money, and would put another lump of an engine in place of this lump of an engine. Not the best idea, unless it was taken to the logical extreme and built for boost.
There's the possibility of (5) and (6) too, or even more options, but I haven't fully lost my mind and I've only budgeted half a winter for this, 'cause I DO want to get something done on the GT.
Annnnnnnd.... the peanut gallery erupts in laughter.
