Budget Blow-Thru SBC Turbo kit! (Youtube 355 Update) 

I have also thought about turboing the Vortec 350 in my Suburban for towing. It's frustrating how little information there is out there for it. Everyone just says to LS swap it... Nah. I really hope you can get the dino session done!

Thank you for sharing, hoping this information will help my son and I. We built an engineer with almost exact same spec I used the 292 on 106lc grind delta ghost cam. But might have to change it for this project. We built it in honor of his battle with leukemia and he is about to hopefully take it on a pass or 2. But trying to get everything dialed. It was cool watching him put it all together.

I love it 😀 I'm with you I'm sick of hearing the LS parakeets

Can't wait for the dyno, I am wanting to do this myself

I'm looking forward to seeing it on Nick's dyno 😁👍

I have made my own engine testing stand, it's up and running, and I am having fun playing with it. I have been thinking about a turbo setup, and yours looks like a good template. Looking forward to the dyno test.

Looks amazing can’t wait to see it installed in your car. Gonna copy your head setup on my Monte Carlo project. Already bought the heads and springs

Great work! This is the setup I’m going for so I’ll be here! Thanks brother!

blow through doesn't mean no intercooler, you can have an intercooler on blow through if you want.... cool setup nice job!

I love big power small blocks. But I do think a multiport efi setup is gonna be what I do when I can get to building myself something

Thank you for confirming the tick….. I’ve been trying to track down where the hell it was coming from loosing my mind. Drives just fine. Those rocker arms though. Makes sense

I dig it. I am planning on a very similar set up in my 65 El Camino very soon.

Yes the distributor! 👍

I read an article a while back that said dual plane manifolds don’t have good fuel distribution in a blow thru application. The engine was a SBF and they got good distribution using a single plane Weiand Xcelerator. They also tested a Victor Jr. and it wasn’t as good as the Weiand. David Vizard says the late model SBC roller blocks are good to 550 maybe 600 hp max. He uses 2 piece rear main seal older blocks for any build above 500hp.

Awesome video as always. I'll be taking my 3rd gen trans am I've been building using your vortec tips and tricks to midwest drags next year. I know I've said it before but without your videos I would have spent way more on my sbc build. Got a ford 9 inch on the way with 3.90 gears and a 200 shot nitrous kit to see what she'll do next spring. I ran a 8.6 1/8 mile on cheap street tires, weak fuel pump so couldn't run engine past 5000rpm lol, and 2.70 rear gears. I did get a holley blue fuel pump so I can get 1 last run at a 1/4 mile track and see what it can really do before it gets the upgrades.

Add water methanol as a boost cooler after you get it tuned 😉 snow performance 👍👍

2:26 everything about any small block chevy is really neat. LS is just another pale copy of the original.

Love it! Saving to do the same thing. Let’s see the dyno!

Can't wait for the dyno.. I've got a vortec 5.7 with a comp cams xr276hr-10 with a single ebay 7875 in a 4th gen camaro. Running 12-14 psi. Never dyno'd though

Nice Pulls in Laval

Just saw this engine on Nick’s Garage awesome !

Interesting stuff. Good content.

Jeesh, it's been a while so I've kinda forgotten the specs. These are the eBay heads (AFR clones?) I think? I'm interested to see how they do, a buddy has a N/A small block running these and he's really impressed with 'em. Should be a beast with some boost, and hopefully easier to keep it happy with the EFI setup too.

Love your ideal I’m really thinking of this I have all the parts all but the mad atomic I’m am thinking ls but if I can do 650 to 700 I’m good

😆 I like LS's in the Tahoe or Suburban it came in.

Very cool! You should swap out those rockers.

Great video, putting your cahones on the line too. I love that you added the twist of a turbo on top. How can a metal on metal valve clatter be normal? Somethings not right.

I wonder how would a short stroke like GM 302 with a turbo would be like probably fun

👍

Wont the biggest determining factor be what fuel ? If its a 9/1 motor on pump 93 im thinking about 12Lbs at lowish timing should be ok with no knock? Also,, if you were to put the piston down in the hole some with a 'D dish piston ,,shooting for 8/1 comp. then we can have boost as high as 22ish on pump gas..make a bunch more HP without Knock/danger.

I want that

Any turbo tuning/ignition videos? Very interested. Thinking of selling my LS to build a SBC set up for a turbo

I was just given a 4th gen firebird roller that's already gutted and has a decent rear end my friends dad just wanted to get rid of it no title so racecar this it was I'm going with is this a 4 bolt main

Blow-thru is a carburator setup. It doesn't have anything to do with the inner cooler. You can have a inner cooler and a blow through setup. Blow-thru is when your turbo is pushing air thru the carb instead of the engine sucking the air thru. So the positive pressure in the carb is compensated for other wise you would just blow the fuel back into the bowl. With fuel injection wouldnt you just increase fuel pressure alone side boost or compensate with the fuel map, but a blow thru carb is built a bit different making it a "blow-thru"

Good video I'd like the info on distributer

Hey I had no idea that you really had a trans am I thought that was just in your advertisement for your show cool I've got an 87 GTA digital dash 383 stroker aluminum heads five speed she is fun

I want to build something like this of my 84 accord

You should make a video on how you made that carb hat

I wonder if anyone even knows what a "piss-cutter" is? Where that term came from?

Just curious, How well does the turbo drain into the fuel pump block off work? I’m considering it on my build.

You sell that sbc kit? Where are you located?

Where did you run the oil lines to and from the turbo

Sweet! Be sure you got enough waste gate.

You had it all apart right? Why in the world would you not go to a 383 stroker? Just wondering. But you do have a beautiful build cosmetically though. No disrespect intended. Happy it is not an LS3 build.

Where did you run the oil feed line ?

Awesome build what horse power are you hoping for NA ?

So if this were in a vehicle, how would you run the exhaust? 1 large pipe out the back?

Hello, the system you use is a Holly brand?

Man. I am really new to turbo setups. I was planning on boosting my 355 carbed LT1 but I sort of gave up, it runs really good NA. About 9:1 , rings are gapped for it, forged pistons and rods, aeromotive bypass regulator with boost reference, running an HEI. The oil pan is tapped for the turbo return. I have a Summit 600 carb on there. I have NO clue what to do next. The car is getting painted now. How do I manage the timing??? Can I stay with HEI? Arent you supposed to retard timing under boost???? Should I go with a blow thru carb or EFI??

Much better use twin scroll turbo and divide banks . Long tube from left head +common pipe extend spooling time

Can this fit in a 996 Porsche ?

How long are they crappy manifolds gonna last They fell apart to dust on my 1990 6 bolt 1g turbo dsm I had to scrap it and get cast manifold from Slow boy and 15 years after still not cracked That's my biggest fear Is when the manifolds crack there not cheap

Can I have the part number for the turbo for a 355 motor

How much would you charge to install this in my truck😂😂

What length pushrods did you use with the heads And what inch spacers turbo to manifold

So are you using retrofit lifters?

But that stupid spoiler I need a fiberglass one the paint just won't stay on one

Can I use this on a gen 1 lt1 355

So it fit in a stock 88 gta trans am Pontiac firebird hood

Do you have a machine shop

How much hp can this combo make reliably?

Yes I'm tired of LS turbo vids... give us something different 😊

I wish they would make a turbo set up for a 3rd gen camaro/bird that fit under stock hood.. I dislike them cowl hoods and adds even more cost to a build!!

RU-vid 355 your selling it to me right, please, I want, I need, it......

That looks like way to high of setup to fit under the hood of a camaro or trans am!

Bro u talk way too much
