coils mounted.

finally received the moroso ls1 plug wires i wanted, ill be cutting them soon, but this allowed me to mount the coil brackets and thus the coils. really pleased with my placement decision (originally wanted to go thru FW but decided against it).

i modified a brand new billy boat cat back system.  i went with the BB for the SS build and quality along with the fact its dual pipe with resonators. the mid-pipe to the headers i built myself, its a true dual 2″ pipe with a early stream X-pipe. all mandrel bent construction and welded. i added an o2 bung per pipe just after the headers.

took forever to get right and nearly  lost my thumb,  but im very pleased. god its long.


ITB linkage

someone had asked about connecting the TWM system to the early linkage. here is my solution, using mostly stock bits to keep the adjustments but i made a “Y” for the pin and threaded it to the OE link which was shortened.IMG_4037


the billy boat would not fit the oE surround. nothing a cutter and some sheet wont fix.

really pleased the result below.

to get there, took out a fair bit of the valence and used a thin tin template as a guide for my steel piece
