I got bored this weekend : )

[trbo355]

I turboed my 98 V-6 camaro completely done in ONE weekend! Whew, what a pain in the ass. My fingers are still bleeding from 12 hrs straight of pipe cutting and welding. All thats left is to change the injectors to 42 lb ones but surprisingly the stock 24's are fueling it to 7 lbs boost (at 100% duty cycle LOL).
She feels like an honest 300 ponies and i plan on making an E-85 tune using HP Tuners to make the factory 9.6 to 1 compression a little more boost friendly. Special thanks to Marshall Shaw and the boys at SMC customs for scoring me a crapload of free leftover mandrel bands i used. Total cost including used injectors is maybe 300 bucks.
Long live cheap chineese turbos!

[Ninja_Bear]

Impressive, youre an animal.

Wanna do my infinity while youre at it?

[trbo355]

I dunno. Maybe? I do like building this kind of stuff! This buildup went pretty easy since i bought all the parts 2 years ago and stared at it so many times i knew exactly what had to be done in advance.

[Ninja_Bear]

Im actually pretty interested if you think you can do it...

[sefus]

might need a couple of skid plates on those pipes but man do i love forced induction 6 cylinders.

[Danimal]

How about a 1966 Buick GS with a 455 olds motor. I wonder if we could do a twin Cummins Turbo setup??? Could be interesting!!!! Kinds like your green monster...

[twotons]

You are a ANIMAL Marty, I got the truck tore down, tearing the engine down tonite i think, we will find out how everything looks and maybe do some head gaskets or something, i have been thinking of making alot more power.

[trbo355]

might need a couple of skid plates on those pipes but man do i love forced induction 6 cylinders.

-SefusYeah its a little shitty for ground clearance but not too bad. This pix shows ground clearance a little better Its thick wall piping and i already tested out the durability yesterday. I turned a corner out by the stateline and had no idea the whole road had rutted out into about a foot dropoff and when the tires dropped over the edge it pretty much used the pipes as waterskis as it slid along!

I thought i blew the hell out of all the pipes but it didnt hurt them one bit. So if i dont do any more dumb stuff they should be ok.

When i got the time i would be interested in building turbo stuff for you guys but right now im swamped with other jobs that gotta get done first.

[Ryfly05]

Thats awesome man! Someone else with a modded 3800! We will definately have to race!! Are you going to bring it to dyno day?

[scooter]

thats it, now i wanna turbo my truck :D see how long the 100k mile 350 with 7.5-1 comp will last :D

[trbo355]

Thats awesome man! Someone else with a modded 3800! We will definately have to race!! Are you going to bring it to dyno day?Yeah sure. Might as well! I think the whole thing is gonna max out at 400 hp but thats ok cuz its still way more funner than the 200 hp stock.
I bet the fuel pump will need an upgrade before i go too much higher on boost too. At 9.6 to 1 im pretty sure on a hot summer day its gonna take a water/meth kit and 92 octane to run even the base 7 lbs boost reliably. Those motors are so efficient they only run about 10-12 degrees timing under boost and they still ping pretty bad.

[Ryfly05]

Yeah, I know exactly what you mean about pinging lol. You see my post about the cam I put in? That really helped a lot! Dropped about 3 lbs of boost(now im at ~7.5 psi, used to be 10+), pulls waaay harder, and no detonation running 16* at wot. Im sure I could advance it a little more, or keep the timing the same and run a little more boost. Sounds sweet too.

yeah i bet a cam would help move a little more air thru it and bring the combo together a bit better. My stock cam specs at 180 ish duration @ .050 and .413 lift on a 115 L/C. YUK!

Yup. 182/192 @ .050". ALL 3800's use the same cam. s/c'd, n/a, series 1, 2, and 3. Way to go GM!! :rolleyes:

[silverfdturbo6port]

anyone who needs something tuned or turbo'd let me kno. if the animal marty wont do it or if he gets real busy that is.smc customs is my neighbor so throwing something together isn't a problem just let me know

[trbo355]

Yep SMC can bend up some pretty cool stuff. As long as the bends dont get too close to each other, they can bend some pretty cool shapes in one piece.
They do stainless mandrel stuff too.

[Hilly]

HMMMM.... I'm bored. I think I will turbo my car ?!?!? WTH !!!

Nice job Marty, next time you're bored let me know. My house needs sided!!!

[94blueGSX]

that is amazing for a weekends worth of work. Very nice to have lots of mandrel pieces left over though. good job.

[yay]

damn marty...when can i get my hands dirty with you?

[trbo355]

HMMMM.... I'm bored. I think I will turbo my car ?!?!? WTH !!!

Nice job Marty, next time you're bored let me know. My house needs sided!!!Ha ha, well i have been working on the kids chevelle with him every weekend but ne got sick soooo, i had to do something else. Poof! Turbo : )

[trbo355]

Did a little intercooler add on this weekend to the Camaro. It DOES run better with no more pinging but the most important reason to do it? It looks cooler this way. If you squint, it almost looks like a cool LS1 car instead of a wheezing 6! Heh heh

[Northwest outlaw]

cool deal looks good.

[trbo355]

cool deal looks good.

Thanks! Its amazing what a reduction in air charge temp does to reduce pinging. Its a 9.4 to 1 stock motor and will hold 11 lbs boost on 92 octane. Especially with the cold air temps right now.

[SOMTA]

Looks damn nice there Marty! You ever run it at the track this year to see what it would pull? Think stock the best I have ever heard out of one was low 15's high 14's.

[trbo355]

The stick cars can go 15.3 stock and most auto's like mine ran high 15's. Mine did 15.88 stock and ran a 14.1 at 8 lbs boost. After some race gas and 15 lbs it went 13.40@103 on regular tires. Ive been playing it way safe on fuel and was so rich it almost wouldnt run clean at the track.
I almost had the A/F fixed and it rained out last time so im betting she's got a 12 second run in it once i hit the sweet spot! Im also gonna make a template for the grille opening and cut some sheet aluminum to fill in the perimeter to nest up to the intercooler.

I cant stand it when people hack out the opening and leave it unfinished. It just looks sloppy and butchered. Once i get it done ill post pix of the nice way to do it. LOL

[2bad]

nah, you just have to use a huge enough intercooler to cover the entire spot hah

[Ryfly05]

Thats pretty cool. Hopefully I'll still have my car next year to race ya. You ever think about putting a turbo cam in it? With 15 psi on race gas, and no detonation, I would've expected a lot higher than 103 trap, but that coulda been cause you were running way rich i guess.

[trbo355]

I kinda want to do a cam next. It was so rich that every run i leaned it was bringing the mph up pretty good. Plus it has 3.73 gears and a loose converter thats not right for a turbo application.

[siege racing]

Hell ya marty looks good now we have to watch out for the lil red camaro sh!t lol

[trbo355]

Aww hell your safe from any camaro threat. LOL Its my daily driver so i better not lean on it too hard. From a learning standpoint, its been pretty interesting datalogging before and after intercooling to see the changes. It flows the same grams of MAF at 12 lbs as it did at 15 lbs boost. Granted the air temp is also colder but seat of the pants acceleration and knock resistance are much improved!
Now im thinking i need to put on a more appropriately sized intercooler instead of that little turd i had laying around. I should do some pressure drop tests to check intercooler efficiency too.

[Northwest outlaw]

Marty what turbo and heads are you running?

[trbo355]

Its a chineese special. The same turbo that comes with the SS Autochrome SBC turbo kits. Its not a bad turbo as it specs with a 57mm compressor inducer and a fairly large turbine with a .63 exhaust housing. The motor is the stone stock 3800 in a 98 camaro with 125k miles. So far so good.

[trbo355]

Well i finally cracked the 12's with the turbo camaro last night. 12.55 @ 107 mph aint too bad! Now im gonna hit the nail on the head and slap a NOS system on it tomorrow because the math says another 50 shot will bust the 11 second zone! One day in in the 12's and im bored. Time to try harder to blow it up!
At some point shouldnt i put it on a dyno? Ehhhh, who cares. narrow band O2's tune just fine. (yeah right) LOL

[Jetblack]

That's good Brian, because until now....

When *you* say "a lot more power", I worry.

Have fun TRYING to blow that 3800 up! :D

[trbo355]

Have fun TRYING to blow that 3800 up! :D

They must be tough because i hit it tonight pretty good with a 50 shot and 18 lbs boost and it doesnt care one bit. Now the damn ignition system goes bye bye and will only hold 16 lbs and spray. Now that i think about it, those are STILL the stock plug wires from 1998 so. . . . . . . . . . . . maybe a new set is in order. . . . . . . .Maybe.

Man did that sucker jump up and say hello when i whacked it with the juice! Its gonna go 11.99. I can feel it.

[SOMTA]

Might be different with the 3.8 F-bodies but I know on the wbodies they said the stock wires were typically better/more reliable than aftermarket. My factory wires went 150k or so miles, and I have went through two sets of napa premium wires and trying out some random autozone ones. Am really curious to see how far you could push it. Haven't really looked into what is much different from F-body to W-body block but the bottom end can sure take a damned beating.

[trbo355]

The bottom ends are basically the same except the GTP motors have slightly better rods and lower compression.

[Ryfly05]

Whats your plug gap at? You can also try getting GTP coils from a junkyard or somewhere cheap, as they are stronger than the N/A coils. Wires might help too, the MSD's on the GTP have held up awesome for at least 2 years and countless plug changes.

[trbo355]

Sweet i didnt know the GTP coils were better. Im gonna try the wires and a smaller gap and see if it cures it. 18 lbs boost is about all i want to do so if it just gets by, good enough!

[trbo355]

Got some MSD wires and .025 gap now and this little bastard eats nitrous at 18 lbs smooth as glass! I cant believe all the fun im having with this thing lately. My butt-o-meter (which has proven to be calibrated pretty good) says easy 11 second runs are in the bag. Hope shit dont break till i get a few passes!
