My 1989 C1500 RCSB SS Bed Twin Turbo 5.3
 

Thought I would share my build over here for the ones that do not get on ls1tech often. :)

Anyways, should have her up and running very soon. Here's the scoop!

1989 C1500, Regular Cab SWB, StepSide bed. Junkyard 5.3, TR224 Camshaft, Dual Springs, Pushrods, TH350 Trans, 10" 3200 Converter, Stock 3.08 Gears W/Welded Gears :), 80lb Seimen Deka's, Aeromotive 340 pump, Stainless Lines, C6 Vette Flipped Manifolds, Custom Front Mount Design (By me), Twin CX GT35 T4 Turbo's, 2.5" Hot Side, 3" Downpipes, AEM Wideband, HPTuned by me (3 Bar OLSD), Running on E85.

Suspension, McGaughreys 4/6 Drop with shocks.

My goal is to leave the outside stock as can be, lightly sanded and then satin cleared to keep that old look. Thin whitewalls on stock steelies. I have some cool trick ideas to keep it farmed out. Where the turbos barely poke thru the hood I will be using a 1 gallon metal vegetable can (yes, corn/tomatoe sticker still on can) cut in half and welded to the hood to provide a cooling duct to the turbos. Shovel handle will be attached to the B&M Shifter to shovel thru the gears lol. And of coarse a bail of hay in the back. Rowdy, raw and plain nasty! Gonna be a tire frying monster lol.

Now for the build pics!

Only the exhaust piping supporting the chargers?
That's gonna snap off in about a week. lol

Sigh......

Anyways, I would explain my bracing to you but I do not feel like wasting my finger strength. :deadhorse:

Oh, and thank you for the concern. ;)

Looks like its gonna be a fun project. Would you mind explaining your approach to bracing them to me? How far do you plan to push it boost wise?

Thanks man. It's always the "man, I know everything so I assume your an idiot" response that always tickles me lol.

No problem at all. On the C6 Manifolds they have some sweet flanges that come off the manifolds that the original heat shield is held on by (10mm nuts, underside which is flipped up). I used a couple of strips of angle to bolt them to the manifold and welded to the bottom of the hot side's just for extra support. I have built many turbo vehicles and this is the only actual one I have braced, never have had an issues with any of them "snaping after a week". Hopefully I will have it breathing by next weekend. :)

Well, depending on how it handles e85, I'm shooting for 15psi or so. On my blazer I ran a single on3 76mm, 60lb injectors, 340 pump and 255 pump but ran out of injector at 12psi @ 16 deg. Was seeing 102% duty cycle which I believe it was laying down 550 or so at the tires thru the 4l60. Hoping these 80lbers will give it enough to feed 15psi.

I didn't assume anything...in fact I asked first before making a joke. If you notice the "lol" at the end, that implies humor.
I asked because there's no visible bracing in any of your pics.
I may not know everything....but I've built more than my fair share of turbo and supercharged vehicles over the years and I wrench on some 4000+ HP Pro Turbo cars....I know a few things.

It's all good brother, no harm. I am ready however to paint some stripes on a few roads. :D

Cool, I have a pretty good mental image of what you did. Do you have a pics of how it's braced? I just always like to see different ideas to feed my imagination when I do a future turbo build.

very nice indeed

And you will! I have a fanatic nephew that would love to see you do that. He has a blown 434 early 60s Nova and would love to go turbo. Maybe y'all can hook up and talk cars lol. I want to see your build in person too! Kennedale sometime?

We need a idle clip ASAP! Lol

:drool: I love the build man. Keep us posted!

i'm more curious as to why you didn't want an intercooler for a planned 15psi

I think I saw where he mentioned that he wanted to run e85

Hahaha, no doubt, Nova sounds like a beast! Yup, I do go to Kennedale here and there. I need to go again sometime, it's been a bit. Once I get it going I might take it down the track and see how she does lol.

Me and you both! Hope to have it breathing by next weekend. Waiting on my AN fittings and hose for my turbo feed lines.

Thanks man I appreciate that. Will do along with plenty of videos haha

I thought about intercooling but I am trying to make those turbo's spool as fast as I can. From my previous builds I have noticed the less charge pipe the quicker it spools. :) Annnnd I will be running the good old corn sauce e85. Good stuff

that makes sense on seeing boost faster because there's significantly less air volume to compress without an IC & all the piping. i just ain't seen nobody run that much pressure without intercooling it before - gas or E85

nice...just spray some meth if it gets to hot at that much boost

Love me some C6 manifolds. Love the layout(would love it more with an intercooler haha)!!!

Looks like it'll surprise EVERYONE, especially, if you leave it "i'm an axe murderer red" :)

nice build let them ripp

Lol, I appreciate it! I am really digging the "I'm flippin broke and pissed off look the truck has" haha. I got alot more done the past couple of nights.

Checked off the list..

AN -4 Turbo Lines are all done 100%
Intake is now on for the last time
'03 Tahoe Gas Pedal with TAC Module (I swear GM knew I was putting this in, I'll post up some sweet info on this)
Shifter is in (woohoo, just gotta weld up the shovel handle)
2001 F-Body radiator is in for the final time

On this list tonight..

Finishing up wiring (harness has been done, just wrapping and positioning)
Finishing up Wideband install

Plan on having this crazy thing running this weekend, atleast fired up.

Will post more pics and videos!

It's gonna be sick man. Sick. Can't wait to see the videos. You should take unsuspecting people for rides whenever you can. They'd never see it coming. :dewey:

Keep it up man, again, very cool.

In for idle videos!

V-Series Tech... Hurry up and boost that tahoe brother! Lol

Lol trust me there will be many eyebrows raised, especially the yuppies with their ladies lol.

***UPDATE***

Update for you guys!

Got a couple more things done tonight. Wanted to show you guys a really sweet mounted point for the tac module on these trucks.

Well, I went with DBW setup due to the PCM and Harness I had laying around. The factory 1989 cruise control module is mounted next to the brake booster on the firewall. As I was trying to figure out a good spot to drill and tap some holes to mount the TAC module, I happen to notice the bolt pattern/spacing looked very close to the TAC modules bolt pattern. Guess what…. EXACT same bolt spacing and all, freekin bolted right up haha.

Anyways, couple more teaser pics for your guys…

Tac Module and PCM location

Look at the match up haha

Attachment 113378

Didn't cheap on on this one with the turbo feeds.. AN lines suck to make BTW

Attachment 113379

Attachment 113380

80lbers spaced out (tall versions)

Attachment 113381

F-Body Radiator in (Just gotta slide the fans on and paint the brackets)

And downpipes are all wrapped up (Yes I only used zip ties to hold the wrap in place as I thought I had 3" clamps, but didn't_

Attachment 113385

Badass build man, definitely post up a vid of the first startup!

I appreciate that mang! Trust me I will

UPDATE, well I got a lot accomplished for the day so far, not much more before I can start her up. I took a break from this 103 deg texas heat to show you guys what I made for the farm truck... :)

Shovel Shifter is now completed and I'll tell you this, it feels rowdy having your hand waaaaaaay up on the shifter lol!! I think it kicks ass!

And of coarse after I burned some wood to give it a nice touch lol

Attachment 113293

Now I'm convinced. You're a sick and twisted individual lol! That is so funny! People are gonna be like WTF was that, that just kicked my ass???:dewey:

LMFAOROTFL!! I can picture me pulling away rolling smoke out of the bed (from the other persons view) while they are in shock. haha can't wait

This project is awesome !

Love the twins , thanks for the pics, this gonna give me good ideas when I fab up a twin kit this winter for my buds 07 suburban .

And your not the only one to run big boost on corn juice and no intercooler , so don't worry bout it , corn juice kicks ass , wish I had it round here.

Lmao xD love the shifter :thumb:

If I ever build a rat rod, im stealing your shovel handle shifter idea! :cheers:
