i have an 87 gt that i dropped onto a 3.3 buick engine it has great top end power but no low end anyone know how to get more low end tourqe out of a 3.3. i know why would i do that engine swap well i had it so why not 2.8 blew up and i love the car

I don't know how well this would work, but you might be able to swap the supercharger and related hardware from a series 1 3800SC.

i have one of these too, from a cutlass ciera. does it work pretty good? i have been told the manifold from a 3.8 has an extra bolt hole that the 3.3 does not. anyone confirm? im assuming i could use this to replace my 4 banger, but i dunno of it would be worth it

Well, since the 3300 is just a downsized 3800, you've done the basic work to put in a 3800 or 3800SC. Something to consider. Other than that, I doubt you can add the 3800's supercharger as even between the 3800NA and 3800SC the engines are vastly different. Different heads and intake, etc.

my grandpa had a 93 Cutlas ciera with a 3300 in it and the thing had some nuts
it would flat out haul ass, verry impressive (all Concidering) im suprized to hear that there arnt more of these swaps ut there

------------------

All of the series one engines use the same block and heads. If the 3300 has the same deck height as the 3800 a supercharger from a 3800 would work but you would need to wire it for a supercharged computer and figure how to get the proper sized injectors for the engine.

You can't just add the supercharger. The heads are different between the supercharged and normally aspirated 3800's. The fuel injectors are in the heads, not the intake manifold, on a 3800SC. You'd have to at least swap the heads, intake and blower from a 3800SC, if they'll even fit and then there's the matter of the combustion chamber size. Then there's the matter of the engine surviving. The 3800SC is beefed up to take the boost. The 3800 and 3300 are not. This is not just a matter of bolting on a supercharger.

Just a word of warning. Proceed at your own risk.

*note: I know this is true for SeriesII engines. You'll need to double check for Series I, but this gives you an idea of things to look for.

The 3300 Buick V6 has a smaller bore and stroke than the 3800. The 3300 also has a shorter deck height than the 3800 Series I but has a similar deck height to the 3800 Series II. Thus, the Supercharger from a series I 3800 will not work on the 3300 because the intake on the 3300 is narrower. In theory, however, you might be able to bolt 3800 Series II SC heads, SC, and other parts to the 3300 and make it all work. I am not aware that it has been successfully tried, but for all the work and money involved, I would think that you would be better off using the 3800 Series II to start with.

Other facts about the 3300 V6:

-90 deg V6 Iron block and heads
-No balance shaft even though there appear to be cast-in provisions for it
-Roller camshaft and crank driven oil pump
-Pretty much a scaled down version of the 3800

thanks everyone the one thing i totally forgot about don't ask why is i am using the trans from the buick also duh higher gear raito 3.06 now that my head is out of ----. i will put the gt trans 3.33 in the thing maybe get a little better take off also going to put 17 lb injectors in instead of 15lb engine is very reliable it was in a century i bought for back up car drove it for about 6 mos but sister inlaw lost title and i blew up the 2.8 so said what the heck changed it over and will drive it anywhere been in about 6-7 mos now very happy except for low end not enough for me but still respectable

Now that I think about it the other major problem I have seen with most 3300's (when factory installed) is that GM used very low stall torque converters with these engines. The 3.33 gears in the trans you are talking about using should wake it up a bit as well and if you want a looser torque converter check your TC ID tag up against the following list and you can use a higher stall to enhance take-off performance...

FYxx -- 1420 stall when used with a 3300/3800 V6
FM8C -- 1525 Stall, Cadillac 4.1, 4.5, or 4.9, Viscous TCC
FGxx -- 1630 stall when used with a V6
FLxx -- 1895 stall when used with a V6
FZxx -- 2390 stall when used with a Quad 4
FJxx -- 2060 stall when used with a 3.4 DOHC, 3100, V6, etc
FDxx -- 2090 stall when used with a V6

The first two digits denote approx stall speed. As you can see most 3300's come with a 1420 RPM stall speed which is what makes that engine feel very sluggish off the line. For the Fiero, I recommend an FJ or FD code converter as it will give you a little more stall and probably won't effect gas mileage that much.

thanks helps alot just want that little extra you know
