oh, and just curious, are you by chance going to weld in some of those bad dog or similar frame rail reinforcements to hold the extra torque output?
I hadn't planned on it, but I do plan to do a full on frame rail replacement in the future. My frame rails are solid in the engine bay, and decent the rest of the way back. Eventually i'll be replacing all of them, so I'll just wait. Plenty of Z's in worse shape with LSx's running around just fine.

lookin good!

What is that, your spark plug wire zip tied to the side for first start up? Just gonna get a boot for it, or what? Katech has some for what seems to be a decent price just for boots...



I've got a few cams laying around here too, maybe I'll have to snag your idea, haha.

Exactly on the ZT's. I'll look around for some angled boots.

So are these just conversion ends for standard wires? If so, I like it.

Its for the ends only. One kit comes with two boots and two metal ends that have the ability to adjust to different angles. I put the part number for them under the pic. Its part number 3301 from MSD. I bought mine at Oreillys for around $5. They had to order them and were at the store the next day.

yeah, looks like that one on cyl. 3 in the pic still has a stock end on it??

...steepss, you plan on putting these ends onto your taylors you have in your pics, or use your OE wires or something?

All of my wires are taylors. I don't have any stock ones, and i'd rather not butcher these.

Well the mufflers and 3 bolt flanges showed up yesterday, and the mandrel bend builder kit should be here monday. I also ordered the remainder of the wiring, which should be here either tomorrow or monday. I also ordered a full poly bushing kit ($$$), which will be in around wednesday. In the meantime, I'm going to pay a good friend of mine a visit this weekend to tear down the the t56 and learn to rebuild them myself. I also completed the above mentioned relay panel in aluminum, which i'll post pics of later. Thas all for today!

Well I spent the afternoon, and the first quarter of the game at the shop. oops lol

Anyway, I took a picture from the side to give you an idea of the ground clearance. It is nothing short of excellent. The engine is held up by blocks because the tranny is out and I didn't want it to sag.

Took the trans apart at a friends, then brought the case back to powerwash/ clean and get it ready to put back together. I went ahead and assembled it so i can use it for mock up for the exhaust build.

ALSO took out the struts to prep them for the coilovers, new brakes, and removed the SPINDLE PINS (S30 guys know what i'm sayin)

I don't see what the big deal is?

this one came out. Its either been replaced, or is the best condition one on the planet.

Ah baby. Brings back memories! I did the spindle pins just because of everyone always talking about them. Sort of a Z car right of passage. I made a puller out of an old scissors jack. Like you one came out with no drama, the second wanted drama. The one thing I did do is lube it up for two weeks prior to the pull.

That motor is tucked up there well.

Did you do anything to your rear diff mount or to get the nose of the diff down? I had to rebuild my Ron Tyler diff mount when the old one got all bent out of shape. My drive line angles are perfect now.

I haven't done anything with the mount as of yet. I'm having a friend of mine cut out the RT diff mount with his waterjet, and then I'll weld it together. Are you suggesting that the rear needs to come up, or the nose down, ,or both?

Well parts have been showing up right and left. I was in Dallas all weekend for a convention, and now I get back and I'm swamped with school work. Not to mention VALENTINES day... what a worthless holiday. So the GF will keep me out of the shop yet another evening.

Anyway, the stuff that's showed up:

-All t56 parts for a stage 2 rebuild- should get it together this weekend
- THESE - Rota RB-r 17x9.5 (4)

You need to measure the angles and find out. In the stock position my diff had a pretty good nose up angle. That meant I needed to tilt the back of the engine down to match. Getting a carb under a stock hood meant mounting the motor as low as I could. This left the back of the trans hanging way low. The overall U joint angles with the stock diff mount were excessive too.

To level the diff I used spacers to get the nose down and drilled out the rear mustache bar bushings (ala JTR) to bring the rear up. I got the nose so low I had to clearance the front diff cross member with a BFH to keep the pinion yoke from hitting it. My trans and diff angles are now dead on with under 3 degrees of U joint angle.

Getting the motor a little higher in the engine bay means you don't need to level the diff as much.
