Dont really need the aluminum intake manifold as long as you keep boost lower (under 12psi). Also, the supercharged guys can just run a gutted supercharger with a block off plate ZZP sells. Finally, People should understand and know that this is just the hard parts... you'll still need a fuel system, (injectors & pump) fuel pump rewiring kit ( Stock fuel pump wiring will not support an aggressive fuel pump), 3" exhaust, and a tune with HP Tuners. Trust me, it gets very expensive very quickly 😂 oh, R.I.P 4T65e 😂
The plastic intake just melts might as well get series 3 intake
Due to the age of these engines and most still have the original series 2 plastic intake with tons of heat & cool down cycles making the intake weak and prone to blowing up or massive vacuum leaks it worth upgrading to series 3 upper with throttle body adapter. making the series 3 intake the only option for turbo setups.
Also, be sure to block PCV valve and passages, or the new boost in the top end will cause problems. Open breather and/or vented catch can is the simplest solution.
I’m learning a lot of car stuff and am pretty new could you explain a bit more into what you mean and how one would do that
@@Lil94FB the original PCV passages expect to deal with normal airways and vacuum conditions the engine was designed to have, but when you add boost starting out ahead of the throttle body, the PCV passages will get hit with pressure that it sends down into the crankcase where it isn't meant to have pressure. On turbo 3800's, the least complicated way to prevent this is to block the 2 passages (vent path thru PCV valve, and fresh air draw ahead of throttle blade) and add a breather on the valve cover oil cap to vent crankcase pressure. More elaborate solutions exist with extra components, but this is the easiest surefire method to avoid vacuum issues and engine seal damage over time.
@@dezldave961 how would you block the passage some kind of bolt on extra or
@@Lil94FB for the PCV valve, I just pack the top of it with RTV... For the TB side on a Series 2, you can tap/plug the opening or use a TB adapter or spacer plate that blocks it. On a Series 3, you can cap or plug the external line behind the TB.
@@dezldave961 could you elaborate on those abbreviations
I don't even have a 3800 but I watched this cuz it's super interesting
Appreciate it
This guy got the crossover picture at 1:03 from my post on a forum. Crazy to think they were all just parts in a box a few years ago now it's a turbo whistling monster 😂
What psi are you running? Hows your transmission holding up to the turbo kit.
20psi stock transmission believe it or not I blew the motor first. Ran lean during the top end of a WOT run and chipped number #5. Doing the full rebuild on the block almost done waiting on gaskets. As for the transmission no issues. Never did a dig in it no burn outs I don't WOT till about 50mph+ still holding. If it goes out I'm not guna play around with rebuilding it all F23 5 speed swap it. It's a 5 speed manual from a Pontiac Sunfire seen a couple of videos on it. Definitely looks like the way to go
Thats surprising about your transmission. Usually you hear so many horror stories once a turbo is installed on a 3800 the transmission blows. Seems like the 5 speed is what most peoples solution is instead going with the northstar transmission once you hit a certain horsepower level.
Oh for sure the Northstar transmission is doable but a lot more fabrication involved the F23 is a direct match. Sure some custom axles and a little bit of wiring but overall seems to be a stronger choice. And at the end of the day it is a manual so worst case scenario your looking at a clutch replacement not a entire transmission.
Not sure of the merrit to this, but my little brother suggested taking a look at the Saturn Vue axles, as they have a center support section for the longer track width. Pardon my ignorance, but it might prove fruitful to look into!
Excellent video. Thank you. Do you have a video on tuning after turboing?
At the moment dont have a video on tuning. a tuning video for hp tuning software for boosted 3800 setups is in the works just don't have a time frame on when it will be released yet.
I'd have to look into it more but my guess is that if you want to do a mild build for under 500 whp you should just do a top swap.
If you want to do more horsepower, my advice is to go with a L67 (the supercharged variant of the 3.8 series 2) and boost the shit out of it. 20 PSI should hold up pretty well. Get a garret supercharger or a b&w. The lower compression of the L67 will make more boost safely.
As for the intake manifold, people have said to use a gutted out supercharger and fab a plate. Never heard of this before but sounds like a good option, especially if you already have the L67.
If you want to do some machine work you can mill 0.100" off of the piston and fit some LS gt2 cams in there and use shorter gaskets. That's pretty extreme though and have only heard of ZZP doing it.
Cool video
Thanks
Have an 06 Monte Carlo LTZ with the 3900 v6. I want to get at least 400hp out of it. Not gonna race it but I don't wanna be left behind 😂 Thank you for the ideas and guidance.
Your welcome
The Only Downside Is The Transmission. But Maybe The Platform Will Get Popular Again And The Aftermarket Support For The 4T65E Will Come Back. Last I Checked The 4T65E Has Fell Off Substantially. Not Very Many Of Us Left Riding Around With The Torsen LSD In Thier 4T65E Or 1" Drive Chains lol.
I agree that the downside of the performances aspect for the 3800/ls4 platform is the transmission (4t65e). Which is starting to make the hard to find parts cost to much compared the the cars value like a 1"chain or torsen lsd,etc. Which is why ive seen more people switch or gravitate to the rear wheel drive cars from general motor like the g8,gto,camaros, chevy ss,etc due to the cost and availability of things.
Add injectors, flexfuel sensor and hoses, fuel pump, wideband sensor and gauges(oil pressure, temp) HPtuners or standalone tuning setup + harness.
Those things are definitely needed also. The focus on this video was the engine parts like turbo,piping, intercooler,etc. Then to make a separate video about the tuning aspect and electrical parts needed like what you listed.
Yay, my downpipe made a cameo at 2:55 (note, it's the $600 Stattama T4 3" one for 500+hp builds... The Z3 one is the $250 version for this kind of build).
Was up dave and That's funny got over 500hp on the Z3 crossover 20psi E-85. And for sure on plugging the holes in the LIM(you saved me on that one)it all blow white smoke like a fog machine if you don't.
@@joselozoya8584 Ya, you can certainly shove the air by force thru the non-ideal path. I think the main issue would be backpressure, if you get into the optimization of your setup, for the long-run and incremental gains.
Yes sir a bigger crossover and different wastegate location will drop back pressure but like you said for incremental gains 600$ vs 250$ doesn't seem fiesable when 500hp is moderately doable with the cheaper one IMO. Just trying to not discourage anyone from trying to make some power with the cheaper stuff that's all.
@@joselozoya8584 if you knew my mod history, you'd know I'm all for getting the absolute most from minimal investment (also make comments in vids and the forum about tips to save here and there). Took 20yrs to finally get to spend a little extra for more appropriate components to push as hard as I am. We can certainly put a budget setup on the edge to make a number, but mine does it on low boost and pump 93 now. I built it to be quite a bit higher and try for 10's near full weight (absolutely useless on the street, so not suggesting anyone take that exact path).
@@joselozoya8584he what? Absolute menace
ive got an 08 Lucerne 3800 with 50k, i really wanna do this but there isnt much info on the series 3 turbo wise i havent see a build of a lucerne before
2008 3800 cars aren't able to be tuned with a hptuners or other software. The ones I've seen convert there cars to the older 2004-07 pcms or have to run a stand alone system like holley. When someone cracks the code on the 2008 pcms then you would see more v6 Lucerne modified.
What would it take to add a stock supercharger to a 1990 Oldsmobile delta 88 fwd 3800? Better to get a donor car for the computer, supercharger, lower intake and accessories from an early park avenue yes
To do the swap properly it would require a donor vehicle since those parts are harder to come by now adays. If your wanting better performance and more power I would say it would be easier to upgrade to a series 2 3800 supercharged engine instead for the amount of effort and due to the larger aftermarket support available for the series 2 & 3 3800s.
Swap the heads too
Will this setup work on a 2002 Firebird 3.8 V6? Because I know the 3800 series 2 is not the 3800 fwd.
the exhaust parts or the metal intake manifold swap talked about in the video will only work for the 3800 fwd stuff. but everything else talked about will work for the 3800 in firebirds/camaros also. here's a link to the exhaust parts that would for your firebird-ebay.us/bzc3Ls
I got a amr 500 supercharger that I was wondering will it help my 97 3.8 Camero run better
Amr500 Superchargers run efficiently on engines under 2.0 like Hondas, Subaru, chevy cobalts,etc. As a alternative I would look for a vortech supercharger from a lt1 camaro/firebird or eaton style Supercharger from the front wheel drive 3800s.
Is there a intake manifold spacer, and is there a TB swap... I plan on buying a SS already supercharged and want some easy mods to go with the 32 spindle.
Zzperformance makes a throttle body spacer and also a spacer that goes between the supercharger and lower intake manifold.
@@gaspoweredgarage I know a mustang tb will work as well...I had a 07 TL and there's a adapter plate for the 3800 supercharger
Hey man I’m trying to too swap my na 3.8 04 Grand Prix and was wondering which throttle body I would need when I put on a supercharger
For your top swap you need to run a 2004-08 grand prix supercharged throttle body. Since your throttle body is electronic compared to the 97-03 cars are cable based. Its best to run a 2004-08 supercharger also so you can eliminate needing a adapter like the older 3800s
@@gaspoweredgarage thank you so much man your awesome
Your welcome
Can you please tell me what I can do to my Pontiac 2008 gp
What do you want to achieve or accomplish with your grand prix?
could you tell me what I need to do with a 1989 Buick Reatta gen1 3800....
You can use the parts talked about in the video except for the intake manifold/throttle body setup that series 2/3 only. The exhaust part i would use your existing and weld a turbo flange on the crossover pipe. A turbo downpipe is going to need to be custom for your car. The other parts like turbo, wastegate ,oil feed line, blow off valve, bigger fuel injectors from the video can be used. I would recommend going with a bigger fuel pump also.
Let me ask you this question see if you know I have a series 2 3800 regal and I recently tried to bulletproof it with series 3 and the only issue is my mechanic friend thinks we have to block of the two coolant ports going to the intake manifold as they will dead end and no where for coolant to flow idk how true this is I have your same adapter you show so I did everything alluminum lim gaskets metal coolant elbows just not the top and I have it and it pisses me off cause he felt we were unable to do it without plugs and we didn’t want to take lim back off I was wonder do I have to plug it at all or if se can we fine find freeze plugs to tap currently I call it 95% bulletproof as the metal intake is not on… your insight is much appreciated…
for the 3800's i convert for friends or customers i find out which way there going all out performance or daily then that tell me to plug those coolant bypass ports or not. my personal setup i was running a series 2 3800 with the series 3 upper metal intake i didn't do the coolant port bypass. now if your going for more performance then i would recommend plugging the two ports which will lower some temps around the throttle body area when your running a adapter for either the l67 or northstar throttle body with the series 3 upper. now the 3800 that get top swapped with superchargers i automatically plug those ports since superchargers produce enough heat already and anyway to keep heat down give more horsepower and torque and longer life on supercharger parts also.
So if you don’t block them nothing will happen just not cooling the throttle body I was more or less just trying to make her get crazy mileage out of her planed to stay n/a series 3 top so like having the l26 without the fly by wire setup
Thanks for the fast reply as wel
Ok last question do you happened to know what plug size would fit the n/a car wholes to block them off they at eyeball glance look like 3/8 or 1/4”??
You need
Quantity two - 1/4 npt plugs
One - 1/4 npt tap.
Wonder if I can use the same idea custom doing the Impala 3500 stock engine like that.
you can use the same idea for your impala with the 3500. The only thing is your doing a lot more custom work at the moment. Do to all the comments i've got in the works a video going over turbo parts for the 3400/3500/3900 engines.
@@gaspoweredgaragethat sounds awesome. I got a 2007 Impala with the 3500 VVT engine. Don’t want to do anything crazy to it but an equal length exhaust, maybe fabbing the ZZPerformance one to fit, and some tuning would be nice. Also some transmission work, maybe a a new final drive ratio. The gearing is so long on these, it tops out at its governed speed in 3rd gear with some RPM to go. Sits at 2,000rpm at 80mph.
@@iDrive4fun93 a transmission shift kit would improve some of your transmission issues till you do a final drive ratio change.
@@gaspoweredgarage it’s my daily so I don’t want to go crazy with it, but a shift kit should improve reliability. It’s a 4t65e so I should be able to get the one from ZZPERFORMANCE cause it’s the same transmission from the series 3 3800 Pontiac GXP cars.
I have a 2001 GTP (L67) and a 2004 GTP (L32). Instead of buying the N/A lower and upper intakes, could I just remove the rotor pack from the supercharger and let the turbocharged air flow right through it?
You can remove the rotor pack and use the zzp supercharger block off plate or make your own. Then use just the supercharger case instead. I just like the n/a intake setup so I can add ports into the upper intake for boost gauges or vacuum sources.

Is that a Malibu behind you? Please tell me a 3800 Is going in that!!!!!!
Yes its a 81 malibu I'm building. At the moment I'm torn between a 3800 from a holden/firebird/camaro with a vortech supercharger or a doing a turbo 4.3 vortec v6 instead of the small block chevy v8 thats already installed in it.
thank god i found this video gonna be turbocharging my 2005 monte carlo LT
wanna be at least 400hp cause stock the lt has 200
400 horsepower is definitely achievable with turbo especially the two turbo sizes i talk about in the video.
Those internals might feel a bit of a beating since it didn’t come with forged internals from factory like the L67 and L32 did
Non forged internal are good for about 400-600 horsepower before failing. Forged internals are around 800. Also depending on how conservative the tune is those numbers can vary some and the octane level /type of gas would protect the bottom end also.
@@gaspoweredgarage Non forged like in the L36?
L36 series 2 and l26 series 3 both are non forged internal.
Brother tell me what I need to do to the transmission 4t65e to get it to keep up with the power
What power level are you wanting to achieve?
@@gaspoweredgarage like 350 maybe 400 I just really want to know how can I keep this transmission strong n healthy the rebuild might be too expensive for me
@@gaspoweredgarage what do you recommend I do to the transmission ?
Budget friendly answer is a shift kit, upgraded cv axles and don't run slicks and stay away from doing burnouts. The more indept answer is in the works in a stand alone video going over transmission upgrades worth going with for a 4t65e thats coming soon.
@@gaspoweredgarage thank you so much already did the shift kit but she was slipping I think she needs to be replaced I threw in some locus transmission oil stop slip and it’s working so FAR ! . But I did change the filter the oil and added magnet to the pan changed the tcc solenoid it’s been a trip brother .
I miss my GP every day....
There's still plenty of them cheap enough to buy and build how your last one was.
I want 400hp so bad
400hp is easy to achieve with a 3800.
