Hello there, this seems to be the most active reservoir of KE30 knowledge on the net that I have found so far and I do intend to utilize this knowledge as much as I can. Thank you all for the help you have so far given through your posts, and hopefully will continue to give.
I'm going to be picking up a TE31 (American) in decent condition this weekend, weather willing and under the assumption that someone doesn't swoop in and buy it out from under me. Which is exactly what happened with a '69 Sprinter a few months back. That one still gives me the sniffles, although the fact that it was completely rusted after sitting for 30 years under a tarp and would have required a major resoration does ease the pain.
Anyways, the TE31 is a five speed deluxe two door that was manufactured in December of '78. The plan for the car is to turn it into a purpose built race car over the next 5-6 months in preperation for next year's racing season (at least on this side of the globe), and I have been researching what I am planning to do to the car.
For starters, I'm not looking to build a powerful car, well at least for a while.
In fact, I would rather leave the engine and drivetrain as close to stock as I can and just concentrate on getting to know the quirks and characteristics of the car until power becomes a limiting factor.
So what do I plan to do to the car? Well, read on:
First off, the interior isn't in very good condition. So, what better excuse could I ask for to gut the car and get to work? The plan is to strip the car all the way down to the metal, repair or replace any unpleasant surprises I find, and start from the bottom up.
Then it will be time to break out the trusty MIG torch, weld every seam, reinforce the body, and weld in a proper roll cage. While I shouldn't need a full cage as I long as I'm running the 2TC in stock or even moderately modified condition, I might as well get that out of the way while I have the car down to the shell and time to do it. Besides, safety is a good thing. So is structural rigidity.
While I'm at it, I might as well spend a day rerouting the wiring and filling the frame members with stiffening foam.
Moving along, next on the list of things to work on is suspension and handling. This is also where things get a bit tricky and less certain. I.e. any advice is appreciated.
On the front, it would seem that either AE86 or Silvia front suspension are both bolt-on affairs and the two wisest choices. Both are widely available, both have lots of aftermarket support, and I don't have a moral qualm with putting Nissan equipment in a Toyota. In either case, upgrading to coilovers and upgrading the brakes will be about the same for either choice, although because the stock brakes for either should show an noticeable improvement over the stock brakes as it is, the latter shouldn't be necessary until I'm ready to work on improving engine power as well. In light of this, is there any reason why one is better than the other?
Whatever the choice, urethane bushings and stainless brake lines will also be installed at the same time.
Also, perhaps I just have terrible luck with search results, but what options do I have for the steering? Haven't found anything beyond a whisper about T/C rods, rod ends, rack/column options, solid couplers, or the like.
On the rear, I'm going to keep with the leaf springs; no coil conversions here. From what I've been able to find out, my basic option is obviously to reset the springs and add leaves as needed; doubling two KE35 leaf packs was mentioned in the FAQ. Although KE35s are a bit of a rarity here, which makes obtaining the leaf packs even more of a challenge. Another more drastic option would be to put composite leaf springs in the rear, although this will probably be reserved for later (i.e. when the steel leaves become too bent and deformed).
I may or may not install an LSD. Depending on what I can find used, the money to buy a new aftermarket LSD may be better used elsewhere. Definitely something I will decide on when I start taking the car to the track to get some practice with.
Beyond that, wheels and rubber are going to be a must, although fragile ricer wheels tend to break so I will probably be looking for a used set(s) of datsun iron cross/RX7/Starion wheels and worry about rotational mass when it comes time to start looking into squeezing more power out of the car.
The engine and drivetrain aren't going to be receiving too much love; as I said earlier I need to get used to the car with stock power before I go making it faster (does not include making the car lighter to better utilize the power it already has).
However I do expect that after 28 years I will have to replace some all lines and perform general maintenance on the engine no matter how good of condition it is in.
Probably a good time to drop in a new radiator as well, can't imagine the original will be too clean on the inside, and it would be a prefect time too put in a bigger rad to keep things nice and chilly. An aftermarket oil cooler can wait until I starting driving the car and determine whether the stock engine will even be getting hot enough to necessitate one.
Eventually I intend to get a scatter plate, driveshaft hoops, overflow catch, and various other regulation equipment out of the way if I start modifying the engine but I won't be crossing that bridge until lightened flywheels, one piece driveshafts and the like.
Aside from all that, I'll be getting a grippy bucket, harness, fire extinguisher, and anything else I might have left out.
So I suppose that is about it, does anyone have any recommendations, advice, or corrections to any of the above?
Definitely looking forward to building the car, it will be fun.
