These motors take 4.6 qts of oil. (I know bc I'm an auto technician and I
change oil in these every day) from personal experience... iv found that
the best way to wake these up is to run 4qts of Mobil 1 full synthetic
(5-30 is what this takes) with the other 0.6 qts Lucas additive. Along with
that, run 93 octane premium, always premium. If you are able to, use Shell
V-Power premium gas. Shell VPower premium gasoline is the next thing to
formula one car fuel. And it costs a just as much as every other premium
gas out there. Nice job on the home made intake. This should help out a

Hey man thanks for the info! I have a 97 GTP, it threw a rod........ It had
some basic mods cold air intake, smaller supercharger pulley, 3 inch
exhaust with high flow mufflers. I'm in the process of pulling the motor.
When I rebuild I want to do some more mods.. but don't want to get too
crazy! I'm looking for basic mods. Probably go with better coils plugs and
injecters. Need to know what kind of good tuner pcms are out there aswell.

Author evilcowboy (2 months)
Got a L36 (yeah I know not a L67) but still liked it and the first mod I
did to mine was the aluminum gasket upgrade with aluminum elbows and
replace the UIM all together with a new one.

The second was to dump and flush the radiator and replace with conventional

The third was to upgrade with Heavy duty sway links (gm made plastic
spacers on the stock ones)

I painted the acoustic cover black and red (not really a mod but the grey
cover bothered the shit out of me)

New plugs and wires and new pcv and some other small stuff (coolant stepper
motor for the dash springs to mind had to solder a new one in)

The stupid pcv valve almost needs 3 o rings to properly seat and not
whistle. I put a small one below the pcv valve where it goes normally, Then
I had to put one under the spring to add extra push on the pcv valve into
it's seat so it wouldn't work loose and cause the whistle and of course the
big orange o ring. This has stopped the whistle that sounds like a belt
squeal so far. If it is not done eventually you'll hear a nice squeal sound
and it will cause the engine to stumble after starting sometimes. You'll
also throw a small evap leak code. It's just a pretty stupid design for it
to be honest.

good vid with good tips though

Author Eric Mietz (5 months)
upgrade that mass air flow sensor.. these 3800 MAFs as opposed to their
cousin motors 3400 and 3100 MAFs are very peticular and their threshold
values are not what they should be with increased air mass. ( this may have
changed with your tuner along the lines of ecm re-call and personalization)
otherwise never hurts to throw some high electrical energy output ignition
coils on there higher dwells, stronger spark, more complete combustion
cycle, less carbon build up overall increased engine efficency. you may
want to replace alternator with a higher output due to increased demand for
voltage and possibly install a gel cell battery. isnt neccessary but,
doesnt hurt. again related to the mass air flow, (i assume youve done this)
remove that slighty co-efficent MAF screen on the throttle body. only
maintenance from there is to clean your MAF more frequently (which you
should be anyway given the performance filter and location in which its
installed). other than that you can always invest in a 4t65e HD transaxle
and some L67 fuel injectors (if not already equipped). sorry once agin with
the MAF sensor installing a performance aftermarket can sometimes loop up
the ho2s and furthermore catalyst efficency. just something to think about.

it was designed by buick when all the different brands made their own
motor. the roots of the 3800 date back to the fireball v6 made by buick in
1962. the 3800 was designed to be in buicks , but gm seen it wa s a great
motor and put it in alot more cars. the 3800 is a buick v6.

Author John fromSpace (1 year)
Sweet man! Yeah these Supercharged 3800s are Cobras on a smaller and
Cheaper scale. Same Idea, easy to add power fast and it has that cool Super
Charger whine once you get an intake on it. I would go
intake,Intercooler,Modular Pulley system and a tuner just to see if you can
run a 3.2. 3,3 should be no problem though. Riv and Cobra, cool combination!

You are stupid, and have no idea what the fuck you are talking about, but
thats ok. The fault is you actually believing your own bullshit since you
bullshit so much. Being a dick does NOT require being a boner all the time.
It is due to you stroking your ego all day. The side effects of being a
boner all the time is pissing in your own face a few times every day. maybe
I am wrong. Maybe you have avoided pissing in your face by being
"needle-dicked". This would also explain your shitty attitude.

@JohnFromSpace I picked up the riv yesterday. On the drive home i gunned it

area, and the later in the day the emergency brake light went on and won't

little old lady. I have a bad feeling about modding this car now. I am

Great vid. Word of advise - when video recording, always have the light

coming (garage door being open) into the camera causing focusing problems.

Author Juan Mares (1 year)
L36 is a Series 2 3.8, L26/L36 are popular for Supercharging swaps due to
their higher compression ratio, matched with a top swap as many call it,
which is basically swapping over Heads, Lim, Supercharger, Injectors, etc
from a L67/L32, they can be a very good combination if done right. If your
average Joe puts it together half assed and beats on it, expect him to be
crying in forums about how his motor blew up.
