340 Conquest revisited

I finally got a chance to look at the Conquest(s) that my friend's kid has for sale... I think I'm going ahead with this plan.

The package deal includes two cars, both TSi models; one is an '86 and the other is an '87.

Both cars are identically optioned, being red with black leather guts and 5-speeds; both cars are complete except the '86 is missing the front seats (he claims he still owns them but I think they're gone for good) and the left front fender. The '87 was the car he was working on; it's got a full 3" exhaust after the turbo with no converter. He completely smoked the shortblock in that one (I've not seen four heat-blued rods before :eek: ), but there's a good core shortblock in the '86.

As is customary, the front spoiler on the '86 is a total loss; the '87's is cracked but repairable. Both cars still sport all four of their cool-looking factory 16" wheels, the '87 even has new rubber. The wheels on the '86 are literally mint while the clear is flaking on the '87 wheels (but no apparent corrosion).

The only real problem other than some minor quarter rust on the '86 (easy fix) and a fair dent in the right-rear of the '87 is that both cars have a soft section of frame in the exact same place. Coincidentally, this is right where the converter sits; I think the heat of the converter probably accelerated the corrosion here. Luckily, the bad spots are short sections (about converter length... hmmm) and in a perfectly-straight section that appears to be nothing more than 2" x 2" square tubing. The floors are solid on both, and the frames are good everywhere else. Sadly, the roof on the '87 has been cut for an aftermarket sunroof; I'd likely remove it and put in a replacement section if possible. At least it doesn't leak.

Both cars have clean MI titles... sorta. There's a story behind that. ;)

Since I have time to kill before I can drive again, my thought here is to rebuild the 2.6 Turbo and install it in one car, and do the other with a 318/340. On the joyous occasion of my license returning, I'd have a decent-mileage driver and a pretty-cool hot rod. Or, I could sell the 2.6L car and recoup some cash.

He's asking $1500 for the pair, but upon my pointing out the soft frame sections, he was really deflated. I'm thinking I should offer less than half that... thoughts?

I'd forgotten how much I really like these cars until I got up next to 'em.
 
One of the magazines (I think it was High Performance Mopar) did a series of articles on a V8 conversion into a Conquest in the early/mid '90s.

I can't get to my old mags right now to find 'em, but it was pretty interesting reading if I recall correctly.
 
I'd say go low on the offer as well. Don't let on how much you really like them and you'll probably have a pretty good chance at getting them.

They're old enough to not be very popular with the ricer crowd and new enough not to be looked at as a real performance era car. That means he's got to find just the right kind of buyer and try to sell them too.

It sounds like your plan has lots of good points to it and probably could be fun to drive the "little" one around for day to day and sneak the "big" one out from time to time for fun.
 
id take a grand with me and offer 500-750 ..there are quite a few fwd mopar guys that would jump at that 1500 price tag...given the cash even i would jump on it
 
The five-speed transmissions in those cars use a 1" x 23-spline input shaft... sound familiar? :dance:

I'm staying low on the offer, because this kid is gonna lose his storage and has been kicked out of his house. Plus, he's unemployed. Waving a wad of $20 bills under his nose will be hard to resist.
 
OK, this is looking like a ridiculously easy swap.
  • The input-shaft spline is the same as an 833; I already found a pilot bearing that would adapt the 5-speed to the Mopar crank.
  • The oil-pressure sender and temp sender both have the same thread as a Mopar V8; the temp sender actually uses the same connector and resistance values but has a longer probe end.
  • There's a ton of room in the engine bay, and the K-member and mounts look eerily similar to an E-body setup; I think redrilling the factory block brackets would do the trick.
  • The exhaust actually goes under the rearend, because it's independent rear suspension (easier routing that way).
  • A Dodge truck hydraulic clutch-release bearing setup looks to be an easy hookup to the clutch master cylinder.
The temptation may be too great here... :dance:
 
I get to drive them I get to drive them I get to drive them.

:calvin:

Witch one is the one I get to blow the engine up in ?:giggedy:
 
Wow Doc, that sounds fanatastic! Certainly too good to pass up from the sound of it.
I'd be all over it like jester on a "Hoff" blow up doll. :)
 
Back in '96 I was looking at a low-miles Conquest on a car lot.
I had the parts to do a 340 install and was looking at this one because it was all there and in nice condition.
Somehow I think they knew I wasn't interested in the engine or tranny because my questions centered around what condition the body was in, whether the stereo worked, interior condition, but nothing about the drivetrain.
I knew then that the engines were mediocre, as far as holding together went and I think they knew I knew.

They were doing their damndest to put me in a Honda or Isuzu, anything but "that Conquest" and they had some super nice offers, but simply wouldn't finance me on the Conquest.
I didn't get it, but they didn't sell me a car, either. [smilie=i:

To this day I still think it was a "Draw In" to get people there so they could mob them.

hey doc keep me posted on the trans and its ability to handle the engine...this might be the needle in a hay stack of 5spd's for v8's...if not i fall back on the supra trans
 
From what I gather, it's actually a Mitsu truck trans with reworked ratios. With the Mopar-style input shaft, it should be at least a little easier to adapt to the V8. The ratios are nice:
  • 1st: 3.37:1 (nice launcher, that)
  • 2nd: 2.04:1
  • 3rd: 1.36:1
  • 4th: 1:1
  • 5th: 0.86:1 overdrive
The rear-axle ratio is 3.54:1. :dance:

Depending on where you look, they're either a very tough tranny, or something of which to rid yourself. Read somewhere about a guy going 9s with one, then read elsewhere that they don't hold up well to modded engines... I don't know which one to believe, but I'd go through the trans fully before I try running it. 20-year-old synchronizers and bearings are probably not up to the task. Either way, I'm hoping I get the chance to find out. :D
 
sooo you want a demon like this eh doc
http://www.allpar.com/mopar/celica-318.html
heres a lil bit that "if" you cant use that 5spd that in there you could do

"with enough work, you could use a mustang T5, tremec 5 speed, viper 6 speed, or toyota supra R154 tranny, but none will be bolt in like the 4 speed swap. closest would be using the supra tranny and a dakota with a dakota AX15 bellhousing (supra tranny will bolt to the bell, but you still have to fab the tranny mount"

soooo now i need to get back to finding me a dak bellhouse since the celica is home
 
Well, I dunno what kind of horseys he's using, but if he can get 700HP out of that 318 with only the little mods he's talking about, there are a ton of bracket racers and NASCAR teams who'd love to talk to him. :D




Of course, NASCAR racers only need go as fast as the script allows.
 
OK, the swap is a little more involved than I thought... I found the HPM article online, but I think some of what he did was overkill, and he also wussed out with the awfulmatic. Equal-length headers seem a bit much with an A500 trans and mild 340 and the trans swap added to the complexity of the installation. His K-member mods, which appear to be at least somewhat necessary, probably added 50lbs to the vehicle weight (as if an all-iron 340 weren't enough). I'm sorry, but custom-machining a SBC race-car water neck rather than spending an hour in a Dayco catalog finding a suitable upper radiator hose seems a bit daft. I guess when you have a machine shop at your disposal, you tend to over-complicate now and again. :D

Still, I'm undaunted... this seems like a project worth doing.
 
well maybe i should show him my lower hose on my 58 ford LOL..its a 2 piece with a plastic coupler in the middle LOL ...ive seen the engine bay minus the enige in that conquest/starion and i see no issues short of modded motor mounts...what we must keep in mind is that the V on our small blocks is much tighter than that of a 350...meaning anywhere a 350 has been we can go in easyer...in those places a 350 wouldnt fit or didnt fit well...ours will fit....would be a fun project to lend a hand on
