This is what i started with. 305 tbi I managed to get this heavy car, with a 305, stock heads, 350 cam, and headers to break 15s in 1/4 mile (15.7 best time). Now i needs more power. And little girl wanting to learn engine

Willie B.

The heads have ls3 2010 camaro valve springs rated for .550 lift. But i got a ls1 00 cam specs rated at .500 for next to nothing. May upgrade to a z06(.525) later. Want to see how this one works first. Alos my son getting his hands dirty as well.

Willie B.

Mostly put back together, got 2 of the nissan skyline turbos while i was in japan. Came off of my skyline, which i blow the the engine due to my friends mis information. " Nissan never made and interferance engine" bull. ( valve Timing off turn engine over boom) Turbo look good. If anything i will use this a mock up ones and upgrade later. Just shooting for 5 psi for now. Should have brought my nissan gtIr pulsar (sr20det awd)back. Or do something different like a rb25det swap in my third gen. But love that v8 rumble.

Willie B.

After struggling to line of the custom motor mounts with the tranny bolted up, for hours. Finally in

Willie B.

Decide to mount the turbo in front out of the engine bay. Also decide to keep the truck intake and mounting hardware i wanted a cowl hood anyway.

Where at in NC are you located?

Looks pretty good so far. The truck alt will still hit a cowl hood but relo brackets are too hard to make. Id suggest turning up the boost as 5psi wont give much in your 5.3. LM7's LOVE boost though so crank it up and hold on

Eagle223usa

Looking good! That thing should fly compared to the old 305. Nice work.

I'm in the Goldsboro area.

Willie B.

Relocated the alt so i can use that cowl hood. So what you guys think? Think it will work? I used a straight edge to get the alignment right and use that bracket from my 305 for extra surpport. Also mounted the turbos inside the engine bay so i woundnt have to use a salvage pump.

Is the alt mounted to the fenderwell?

I sure hope that's just a brace that's sitting off to the side for the time being.

Moving along, just another reason i am doing a single turbo, i think it will be cheaper, really cheap since i got a steal on the turbo.

Willie B.

No its bolted straight to the block with the two mounting bolts. I used that fender mount as extra surpport. I was going to have the bolt on the fender welded. @ Zones89rs I would have went sinlge believe me i thought about it. But i already had these turbos and its cheaper for me.

I understand, i got my fresh 76 mm with IC and boost controller in trade for a carbed Vic Jr intake i paid 200$ for, LOL.

Willie B.

Well, i decided to go back with the truck accessories. I got a hood from the junk yard for $29. And decided to cut it, then get a hood cowl for it. And weld it on or bond it if i go with a fiberglass one. Its cheaper than actually buy a cowl induction hood or ram air. I figure its cheaper to mod the hood than buy the f-body brackets and intake. Intake $50-100 with injectors maybe or maybe not. Power steering bracket $30-$50. Alternator bracket $80-130. Also the Corvette fuel filter and new line $? My choice hood $29, scoop $50-100. Plus weld or bond time, priceless My measurement for the cut was 15" W and 22"L. Well below the scoop measurement. If someone is planning on doing a 5.3/6.0 swap and your planning on getting a cowl hood or ram air. I feel confident say that the truck intake and alt will fit under that hood. Just be sure to check hood measurement, I'm sure a 2 1/2"-4" inch raise will clear.

Looking good so far Willie. I think that's great that your kids are taking an interest in the project! I have a teenage son that wants nothing to do with my swap. Enjoy

Man, looks like it is going to be close for me with the hood on my TA, it might work, but i will be using a original alternator from the TA, so we will find out:

I hope that means no brace from the alternator to the fender...

Willie B.

Yep no brace all the original stuff that came with 5.3

Hot piping for the driver side turbo done. Next is the passenger side, I turned her over before i started the piping I need to check my grounds and voltage to the pcm. It turn over but didn't fire, and i fuel( because one of the fuel lines start leaking when i turned the key on).

Willie B.

Hey Pocket, on your first boosted setup were you using the stock injectors? Also whens the next NC 3rd gen cruise or meeting?

Pocket

iTrader: (24)

I used 26's NA, 36's with the M90. Have 60's for the M122

Check here for the cruise in's, we're talking about getting them going again since the weather is warming up. TFB is open to anyone but mostly 4th gens show up. We've got some killer 3rds though

Willie B.

So my exhaust is done, but the car still wont start. Turns over strong, I checked the grounds not sure if have only three grounds have anything to do with that. I had a scanner hooked up to and it read the EGR valve of course since i blocked it. And the other was EVAP. Also i checked for spark(pulled a spark plug and turned it over) it was hard to see since i was also turning the key, but i thought i heard it. Any suggestion.

VATS?

Willie B.

I had the vats bypassed. I was wondering, could there be something to do with fuel pressure OR the fuel lines? i have the truck intake so im pretty sure the 3/8 line is the feed and 5/16 return right?

Willie B.

More pics of the exhaust and my hood hope it turns out good if not oh well, i just have to save and just buy one.

five7kid

iTrader: (14)

In both the car and the PCM?

The supply line is 3/8". I don't have a truck intake anymore, but I don't remember the fuel rail having a return.

Willie B.

i bypassed the car and installed the vats module for the pcm, unless those things suck. But would the vats allow it to run for a few seconds then cut out or is that not always the case?

Pocket

iTrader: (24)

See if it runs a few seconds on ether

Depending on the year, truck fuel rails can be had in return or returnless

Willie B.

So your saying disconnected the pcm vats bypass module and then try it? Also does it matter if the pcm is not the original but still from a same year and engine?

My son has a 5.3 bored out to 5.7 with LS1 intake, TB, & injectors, 5.3 MAF, LS1 4L60E, in a 2001 S10 Blazer (originally came with a 4.3). It is being run by the Blazer PCM. It had to be reprogrammed, of course.

For grins, we hooked up a 5.3 PCM (he had picked up an LM7 to swap into his '96 S10, then the S10 was totaled in a parking lot incident - he bought the Blazer with the insurance money). It wouldn't start.

Pocket

iTrader: (24)

Troubleshooting mine, I tried a stock LM7/4L60E PCM on mine and it wouldnt start either

Willie B.

So I got some starting fluid and sprayed it in there, and it fired off for a few seconds. So that means im not getting fuel, so it would be vats or really dirty clogged injectors. guess i need to rechecked that vats module. Could there be anything else

dynodanmanda79

Did you hook up a fuel pressure gauge to see what kind of fuel pressure you're getting to the rail? How are you regulating fuel pressure? are you using the vette filter? or are you using an adjustable fuel pressure regulator? a fuel rail with a built in regulator and return port? what kind of fuel pump are you running? LSx engines need 58 psi at a minimum to run

Willie B.

Yeah i guess it is VATS. Because my for pressure is right a 60 psi when first which the car to on position. Man thats $30 i just gave to Baker Electroix for nothing.

krazefbird

Well I am thouroughly confused. VATS? PCM? I don't know that stuff, I'll just stick to what I got. What's up Willie? Looks good! Still here....not for long though!

Willie B.

How you been Mr. Krazefbird? How much longer do you have here? As for my car its almost there the vats and pcm are relative easy to fix. Should have just done this the first time and have the Vehicle Anti-Theft programmed out. You should swing by to check it out.

rs89todd

How are you making out with the vats? I'm currently gathering parts for a similar swap, I have my t56 and gettin a 6l long block or 5.3 and I've been looking at a few of these posts, my car is a carbed 350 I hope I don't run into vats problems or ill put a carb on er, seems like less headaches....

Willie B.

I still need to get the VATS disabled. Soo, is there anyone in the Raleigh, Durham, Smithfield, Goldsboro, Fayettville, Greenville area of NC with a with a flash tuner that can give me a hand for a reasonable price?

Willie B.

A shot of the engine covers and the pipe still need to wrap the headers and paint the intake piping.

krazefbird

Hagnin in there Willie, bout all I can do. I'm thinkin outta here bout 5 May or so. If I get a chance I might be able to stop by. Or if you get it runnin I'm sure I will see ya. Kinda easy to pick out the third gens! lol

Willie B.

Does any know whats the best way to extended O2 sensor wires, solder or crimps?

Pocket

iTrader: (24)

Solder

Extend the engine harness side, you cannot extend the HO2 sensor lead because it uses stainless wire and solder will not stick to it. Crimping is never a permanent solution

You have to make yours longer? I cut mine in half and they're still to long.

Did you ever get VATS tuned out of the computer yet? Have you thought about getting a mail order tune? to gets VATS tuned out and I'm guessing the computer would also need to be tuned for those turbos too but i'm not sure.

Willie B.

Yeah I sent my pcm off Last Friday, I should have it back this week hopefully. All I wanted was just to have it running before i get it dyno tuned. So Hopefully I will have vids of it running soon.

Willie B.

Well, it seems that nothing is going my way. i got my PCM back today and when i installed, i felt good thinking i was going to hear my car run nope. So im back where i started at. Sand and Street told me that my pcm was reflashed and that they ran it on a one of ther engines. Maybe i need to recheck my wiring? Can O2 stop it frrom running? Could there be anything im overlooking?

Willie B.

Also how do i check the injectors fto see if they are pulsing?

White'89

iTrader: (8)

I'm currently pulling my car in and out of the shop with no o2 sensors installed since I have open manifolds right now. It still starts up and idles well but I cant go much past 10% throttle without it running like crap, so yes it will start without them.

To check the injectors just put a test light on the negative terminal of the battery and turn the key to the ON position and check to see if they are getting power, the same goes for the coils.

Whether they are wired to the correct spots on the PCM connectors is on you.

ZONES89RS

Damn Willie, you are another one making me happy i went carbed, sure it is something simple though. Just a wiring issue you find soon i hope, GL man!
