Ok gentlemen.. here is another update.. i decided to go with Bob Bailey's LTCC conversion, here are some pics..


These are the LS1 coil ends from Taylor, come in a pack of 8


Making my own wires, im using Taylor Spiro-Pro #73251 in red.
and LS1 boot ends Taylor # 46069
Taylor wire crimpers, 43390


I got a tip from one of my friends.. when assembling wires. They are a bee-atch to push into the plug ends with no lube, plus you dont want greasy wires. I was told to use Brake Kleen to lube them... it cleans the wires and terminals and dries clean. Good tip.

Here are some finished ones


Left over wire.. lots of it..


this is the LTCC box mounted on the driver side fender well.. i also used small little rubber O rings under the mounting points to help stave off vibration, some the the box can not have.


Here is how i mounted the coils, without using expensive $200 coil relocation kits.. or other expensive mounts.. mounted them right to the valve covers! NO modifications needed.


Close up


Engine shot.. only 1 side is done...



i should be finishing this up this evening and taking for a drive..

Looks good. I am going this route if my opti craps out.
Oh ****.......

Wrd1972 if your opti craps out it wont work. The ltcc conversion has to have working opti to work.

Op you setup looks real clean.

stevo9389

you did use the non chlorinated brake kleen right?

If I am correct, the cap, rotor can crap out and still work fine with LTCC. Is this correct?

lethal bird

iTrader: (12)

I believe your correct.

Are you not going to mount the other side of the coils?

BOLO

The optical sensor can and may also crap along with it

Every time my opti died it was the optical sensor.

i only managed to complete 1 side, and took a picture... as of right now.. all 8 are mounted.. just need to cut the old coil pink wire and splice in the 2 LTCC pinks to it.. as well as the white module wire..

the brake Kleen i used is the non chlorinated kind... lucky me i guess but whats up with the regular brake kleen?

putting this set up on my car eliminated all wierd stumbles and hiccups during rpm ranges.
my car now rips to redline and idles/cruises just a bit smoother than with opti stock.
great idea mounting without brackets. Simple.

No i mean the other mounting hole for the coils.

I see his point - I'd be wedging rubber isolator under the coil and using a lock nut of some sort - check them for tightness now and then. That single stud mount may allow them to vibrate.

How did this setup end up working for you?

You'll like the LTCC. I've been using the same one for years and have had no problem. Since I travel a whole bunch I did get a spar module for $250. I'm quite sure autozone won't have one. It seems that getting the high voltage and ozone out of the opti makes them last forever.........maybe.



All the wiring for the coils is under the fuel rail covers.

Any idea why the truck coils won't work with it?

The dwell time is different on the truck coils, of course running a ls pcm you can swap them to the cars because you can tune for it in the computer. Since im sure the dwell time for them is programmed into the box for them there is no tuning to change it.
