Ive been lurking long enough and stealing everyones ideals. I starting buying parts for it in nov and have been working on it for about 2 months and have made some pretty good progress.

Ive had the truck since it was new and its been through a few different motors. Its pretty much always had nitrous on it , I got the turbo bug a few years back
and talked myself out of it since I had a decent motor in it. Well I torched a few pistons in it last year over revving the stock pcm so now since I have to rebuild the
motor I figured it was time.

This is my first turbo/boost build , all diy.

Hopefully what Ive got done so far is done right and designed well.
The motor
lt1 383 with 1/2 fill of hard block
trick flow heads, 2.08,1.65
cometic head gaskets

8.8:1 je pistons
scat h beam rods
scat forged crank
splayed billet main caps

planning on running e85

trans will be a th350 with ultra bell and brake
~4000 rpm stall converter

28" tall slicks

turbo is a s480 with bullseye race cover 1.32 ar
JGS 60mm wg/56mm bov
31x12x4 ebay intercooler

Re: 98 sonoma, ltx, s480 build

Im waiting on the motor to get back from the machine shop so that I can build a new alternator bracket, I had to move the alt from low on the pass side to low on the driver side due to the turbo placement. I keep wanting to build the bracket and remember that there is no crankshaft in the motor and kinda hard to mock that up.
I still have quiet a bit of stuff to do. Im trying to get the truck going by early march so that I can get it tuned and out to "pinks all out" in ennis mar 21. I dont know that it will happen or not.

 

Re: 98 sonoma, ltx, s480 build

Looks good man glad to see your moving along and your welds look great

 

Re: 98 sonoma, ltx, s480 build

I dont know about the welds looking great,they will do though. I bought a tig welder so that I could do the alumnium stuff , practiced for about a day before I did the cold side, some of the welds are ok and some look like full on shit. I will get better at it though.

 

Re: 98 sonoma, ltx, s480 build

LOL okay well your welds look a hellofalot better than mine

 

Re: 98 sonoma, ltx, s480 build

very very nice job!, i like the turbo facing forward like you have it. keep up the good work.

 

Re: 98 sonoma, ltx, s480 build

I moved this turbo all over the place and this about the only place I could find that it would fit. I about broke my back one day just moving it around and seeing what all obsticales where involved.

 

Re: 98 sonoma, ltx, s480 build

What did you use for all of the hotside tubing?

 

Re: 98 sonoma, ltx, s480 build

Looks good. Were you able to run a 5" DP all the way out?

Thanks for posting all of the pix!

 

Re: 98 sonoma, ltx, s480 build

14 gauge aluminized mild steel, header kit was from robert1320 everything else was bought off ebay.

 

Re: 98 sonoma, ltx, s480 build

all the way to behind the RF tire! There is no room to go between the frame and engine for a 5" dp. I will try this and see how I like it. May go a different route in the future.

Re: 98 sonoma, ltx, s480 build

I sandblasted all the hot parts today and applied a coat of vht 2000 degree black paint. Going to wrap everthing tomorrow if I have time. I need to grind on some of the welds on the down pipe to pretty it up some, Im only going to wrap down to the vibrant muffler and leave the rest of it just painted because the rf is going to touch it on hard right turns.

 

Re: 98 sonoma, ltx, s480 build

Looks really nice man, keep it up

 

Re: 98 sonoma, ltx, s480 build

most of the welds are just mig welded. I bought a syncrowave 200 last week and have started learning how to use it. I did manage to get the cold side stuff done . I still need lots of practice with it though.
