Obd 1 is not as strictly enforced. My exhaust manifolds are off of a different vehicle and are modified. My o2 sensor was installed on the wrong side of the y. It all passed. 95 4.3 vortec from an Astro van.

I hope what he told me is true. Ive talked with him before about this build and hes helped me with a few things.

But theres no way the stock downpipes to the cat are going to fit.

Theres also another big potential problem... a manual behind this motor.
You should be good, but don’t get crushed if you don’t pass on the first time. It took me 4 times and a few years. Even worse, the new catalytic converter I had installed after the first go round needed to be replaced for the final trip. The carb number was no longer valid. It passed smog every time...

shomsky462 Upper radiator mount done. Radiator is fully mounted. The shiny part is stainless, the black part is some 2" rectangular tube I cut then dimpled.

School starts today so the build is going to slow down but ill still be chipping away at it. I have a long list of smaller things I can take care of here and there when I get the chance.

The next major obstacle will be the dash and wiring. Ive decided to make a new dash, the stock dash is trashed and would take too much effort to reconfigure how I need it. I wont be using any of the vents or any stock gauges, switches etc. The plan, for now, is to make a simple, flat, 2-bend, aluminum dash, with gauges in the center.

shomsky462 Exhaust stuff:

Downpipes are 2.25" and they Y into a 2.5" then there is an 8" flex pipe then a 3 bolt flange.

After the flange there will be a california legal catalytic converter, 2.5" in/out then the plan is to go to 3" after the cat and a magnaflow 14" muffler somewhere above the axle then dump. Im doing what I hope will be acceptable to pass a referee.

The driver side down pipe needed to be routed around a lot of things, the upper link, clutch slave, oil pan, etc.

I made up some heat shields for the clutch slave and the gas tank. Ill probably make another under the passenger floor and the Y. The downpipes are going to get wrapped all the way to the flex pipe.

shomsky462 I have plans to make a small bed in the back, got the steel, wood and everything but Im going to focus my efforts on the things that are going to make it go.

Next up is the fuel tank, mounting and plumbing.

The fuel tank obviously couldnt interfere with the driveshaft and I wanted the filler neck to be somewhat consolidated and pushed closer to the cab to make more room for spare fuel, water, batteries etc.

Fuel tank straps are made from 1/8" x 2" flat bar. Made some keyholes for the 'not so accessible' side and a stainless 5/16" stainless 't-bolt' for the other. A 2.5" thin rubber strip will go in between the straps and tank (Its actually rubber garage door seal, for the bottom).

I had to cut, rotate and weld the filler neck to be positioned correctly. Welded with silicon bronze.

And of course, a stainless filler neck mount for extra bling.

shomsky462 I was doing the rear tube work and the rear shock mounting around the same time.

Here are some shots of the the rear shock mounts, rear bumpstop mounts, and the rear spring perches welded in.

Ill be going with a double cardan rear driveshaft because the angle at ride height is around 13 degrees, so at full droop I felt that the double would be necessary.

I pulled out the smallest leaf at the bottom of the pack. It wasnt even the full length of the spring perch and I figured they would only aid in axle wrap considering how little contact was being made between the leafs and the perch.









08-30-2019 10:45 AM
shomsky462 I finished up most of the front tube work. Mounted the front coilover reservoirs. I still need to mount the top radiator support somehow.

But it was on to the back half.

I rearranged the garage to have a much better "shop flow" and its worked out much better and Ive been going to town on this thing. Im sure the neighbors love me...

shomsky462 Ive been pretty busy working on the rig over the summer. I worked for a month at Cal Poly teaching middle school and high school kids about mechanical engineering and doing various engineering activities for a summer camp thing they have going on.

Here are some pics of the progress so far. Its getting closer...

I knew I had to reinforce the front coilover mounts and running a bar over/around the engine was not an option. Nothing would fit under the hood.

BTW Ive been rolling and bending all this DOM (most of it is cold rolled) by hand. Fun stuff.

This is what I came up with:

zachwrench nice and tight cage I dig it
05-16-2019 12:56 PM
shomsky462 School has been keeping me crazy busy as usual.

Finished up the cage over the cab. Its really tight over the cab, touching in some areas. Painted it by rolling on rustoleum hammered finish (black).

Tig welding this thing had me in some crazy positions, definitely some good practice.

I dont know if ill be running a DSP or not. Honestly I never even considered it until you mentioned it. Seems expensive and time consuming, but what isnt when you want to do it right? I will definitely research it more and see if its the direction I want to go.

I very much appreciate the advice. Your builds/work is insane and quite inspiring. I cant believe I havent seen any of it before. I definitely planned to make a carbon dash panel(s). It mostly depends on how much time I want to spend on making the tooling. Realistically I was thinking of making a shittier version of what you got going. The organic contours of the panels are what have held me up mostly.

Anyways, thanks for the advice and compliments!

*edit: forgot to ask you... are your carbon parts primarily wet layups or pre-preg?

Now you gotta make a carbon dash panel.
That is some killer detail put into your box and system! Looks amazing, very cool. I swear I didnt see this previously before I made mine. I had many different designs in mind before I settled on this and its crazy to see how similar ours are! I for sure would have cut out the hump in the back wall like you did, had I have known that I was going to try and put a full 12" sub right there. But I really didnt want do any more body/sheet metal work.

Couple of questions for you:
Do you have more of a buildup of your truck and/or system?
Did you lay that carbon up yourself and how?
Where did you get that dash topper?

shomsky462 School continues to kick my ass. But at least I get to make carbon fiber stuff if I want/have time.

I made some carbon fiber plates to mount the amplifiers. Isolated them from the rear wall of the cab with some rubber feet made for big speaker cabinets I got on amazon for about $5 (for 8). This was done in hopes of reducing the amount of vibration the amps see. Both sides of the mounting hardware has stainless bonded sealing washers as well.

Amps are:
- Alpine MRV-F300 4 channel. For the speakers/tweaters.
- Alpine MRV-M500 mono. For the sub.

Pics of the passenger side: (The driver side looks identical)

Thanks. I'm excited to smash it as well. Its closer but still a lot of work to be done and lots of money to be spent.
