- Couple WOT runs in my 1986 trans. Setup is a 2005 5.3 stock bottom end, 317 heads, LS6 cam and valvesprings, LS6 intake manifold, and custom fabbed turbo setup with a turbonetics 76mm ball bearing turebo. Currently running 5 PSI but engine will take 12-14 PSI. Car has a T56 tranny with a textralia clutch as well.
love the sound of that spooling turbo , the acceleration must be crazy fast . kudos on your build !
It's been so bad ass to watch this car progress. I also own a 86 but its bone stock at the moment.
Great job man! Hope to see more videos of this beast in the near future.
"There's no replacement for displacement."
hey, that's my line, lol!
i've been saying the same thing for over 20 years.
The car is owned by me. On the baseline dyno, it made 400 rwhp at 5 psi on a VERY conservative street tune with just 14* timing. When bumping it up to 11 psi and tuning it a bit more precise, it put down 563 rwhp as the final number.
Sick ass ride.
I love Pontiacs!
The fun part is this bird is all chevy. I don't know the last engine pontiac designed that was strickly their own.
Devin Dowless Last Pontiac V8s were made in 81, everything after that is corporate GM and Holden
They are made by J&M. And I don't have coilovers, just the stock style setup. Thanks for the compliments man!
technology makes displacement that much better!
Wow what a nice neighborhood.
looks like New york state? Maybe PA? somewhere up north thats for sure!
Fullforce LTX license plates look like maryland
86gtforme Im pretty sure this is in Connecticut.. but I could be wrong.
Atomic Ws6 You're correct. it's Connecticut. at 5:25 that's a Cox cable van that passes by. they are mainly based out west but Connecticut has them as well. Cox is also in Iowa as well. their plates are white and blue but it doesn't look like their plates.
+dmfb68 Cox dominates San Diego county here in SoCal
I know the video old, did you gap your rings? How did your set up run with the stock bottom end?
That is one sick build
are you the same ones that are running from the police on dirt bikes recognize the same street in the houses LOL
Cant wait till I do that to my 82 Chev pickup
Twin walbro 255's in a 4th gen plastic tank assembly, -8 feed line and -6 return. Intercooler is just an ebay CX racing universal 31x12x4"
First off cool video.. Second, Is that 5.3 block the same they put in the FWD Impala SS's? LS4 if i'm correct right?
When you have a fast car you don't need to stop for stop signs xD
how quick is it with those 317s? thinking about running them so I can run a bit more boost but don't want to lose any light to light races ;)
Did you have a Grand National motor in the TA before ?
that's fucking discussing, I love it!
This ones just a plain jane iron block truck 5.3. It's officially called the LM7, and came in silverados and tahoes from 99-07. Same basic engine as an LS4, but with an iron block and a bit less compression I believe.
you sure it'll handle 14 psi with stock ring gaps? and for how long?
Bad ass car.
Older muscle yes, Irocs however can hang turns with the best of em. My 88 Iroc will take any turn my friend's supercharged SS Cobalt can take. My other friend's Mitsu GSX might handle a tad better but unless youre in a seriously insane hairpin turn its the exact same. 3rd gens and newer can really eat up a track, even before mods
amazing setup been following it 2 on TGO i have to say SWEET
He said the 76MM (not 67MM) is holding it back. I replied to the latter part of his comment, disagreeing with his advice of going with a BorgWarner EFR.
how tough was it to get the 5.3 settled into the engine bay? custom mounts, anything like that?
i love third gen trans am and ef civics, am i hallucinating a spark in the middle of the dipstick or is it just the camera?
It is the brand on the serpentine belt.
an LS engine has entirely different motor mounts and a different transmission bolt pattern. you can buy parts to make it work but otherwise it is not a direct bolt in
Sounds great, nice ride!
love the car
building a ls1 ta myself mine is a 87
Nice ride, sounds great.
Would like to see the whole car though. Looks like a nice color
looking to put a 5.3 into a 3rd gen camaro, k1 pistons,wiseco rods, ls6 heads and cams, comp cams valve train kit with twin turbonetics 76mms wit the turbonetics godzilla bov and waste gates, hoping that with a 9in and a th400 maybe make 1000hp at the crank
how did you get on?
@t3h51d3w1nd3r thats the numbers on the belt you see moving,it does look like a spark tho lol
thanks
Sweet ass car
Sweet
He is saying the t67 is too small for the 5.3. So you think a t67 is too small for a 2.0?
Hey I just bought a 3rd Gen 88 gta. I’m looking to do the exact same setup. Or one very similar. I have all tools and very handy & tig welgs are spot on.
I just need general information on how to start and what to buy and where to go.
I just made switch to German tuner world to older muscle, guess my balls decided to drop
Hey man, this Trans am is actually my bros car. He has his own channel, so you might get a lot more info from him. Search for his user name, Transamman305.
thats why its stupid easy it requires no fabrication buy mounts and adapters and stuff and bolt it all together.
What exhaust do you have
Do you have a/c? Build thread?
how many ponies that thing making with the boost you run?
In this vid at 5 psi, it made 405 rwhp. I ended up turning it up to 11 psi and it made 540 rwhp. Just this summer I swapped out the turbo for a larger one and am currently on 16 psi and making somewhere around 700 rwhp. Car is an animal and still running the good old stock bottom end 5.3!
transamman305 Wow, thats amazing youre running 700 horse to the wheels and its the same 5.3 bottom end!! Geez. Can I ask, are you an engineer? The reason I ask is I would love to do a turbo LS motor in my 69 gto, but I dont know how difficult it is? I can do motor work and am fairly mechanical. All the tubing and intercooler and so on just intimidates me! Too bad youre not my neighbor😁
transamman305 did you gap the rings or no?
what fuel pump(s)?
intercooler?
Probably a stupid question but what MPG to do get in a beast like that?
W/ T-56 i would guess and say atleast 22mpg highway
Not stupid at all. With my heavy foot it's tough to say, but I normally will get between 14-18 around town beating on it a bit.
How much hp you making ??
nice gto in the background...
yup, best of both worlds.
neck snapping displacement.......AND a little bit of fuel economy!
xD
bro how muxh HP are she doing?
bolt in to me is anything that doesnt require fabrication
nice
Got a build thread on this bad boy ? =)
Sure do. Search for "project P.I.T.A." over on thirdgen.org and you should find it.
On his setup in this video I'm going to guess ~425-440
what happened to all your videos building this car ?

ats cool stuff
What camber plates are those?
+jeremy shaw J&M products
Whats up man looking to do this swap into my 87 iroc do you know anyone in the nyc area that does them?
What injectors are you running?
60 lbs mototrons
how much hp it has
Can you use stock rear end for this swap
Might want to beef it up a little bit but if you have the money id just go and throw a 9" in there that way you don't have to worry when the thing actually hooks. I went with a Dana 60 in my 78 bird, would definitely do it again
+jeffburgeryo NO, throw out the stock ten bolt, beefing it up won't do anything but waste your money. You have to get another diff, whether it be moser, strange, and if you're up for it a ford, anything but the stock 10 bolt, it'll grenade so fast.
@@LOLKINGBABY no it wont...
Yes Reliable AWD.. But not so reliable Motor.. They are to temperamental for my liking. Learned from experience.
wrong! lm7 is an ls1 series motor different mounts different motor altogether for the most part.
Here's a turbo car set up the way it should be. No 4-cylinder engine will EVER be able to make the kind of horsepower and torque this turbo 5.3 can, especially on only 5 psi of boost. But there are those who think that Evo's, STI's, SRT-4's and other 4-cylinder turbo cars are God's gift to the auto industry, why I and I'm sure many other people will never know! If you want to make BIG power RELIABLY, I'd go with either a V6 or a V8. There's no replacement for displacement.
Maybe on a 2 liter engine, but not here.
Maybe because Sti's and Evo's aren't straight line cars. I wanna see any american muscle perform on the WRC like they do and dont get me wrong i like American Muscle but they have different purposes in m opinion.
get rid of that turbonetics 76mm its holding you back..BORGWARNER EFR FULL-RACE
My biggest fear is to have a engine that sounds like a diesel
u have ac
your swapping a small block gm engine into a car that was equipped with a gm small block its stupid easy
What exhaust do you have
None, lol. The downpipe in this vid came out of the turbo and dumped just past the framerail by the firewall.
O ok
