i seen you guys answer this about supercharging a n/a bonne already and i know you said pcm,wiring harness etc.but what i don't understand is why the n/a engine would be weaker or not able to hold the boost the only reason i know is compression of pistons . usually n/a vehicles having higher compression pistons and maybe sometimes a slightly smaller cc on the heads maybe different cam but you see superchargers for stock engines all the time.but i don't know about superchargers that much.2 differant guys i know ran weind 6-71'* on small block chevy 1 using 7.5:1 with alot of boost and 1 using9.5:1 with low boost stock heads.so i guess what i'm asking is what makes the */c motor any stronger physically then the n/a.i just don't get it.thanks in advance for help.

The biggest thing is the tranny. It is not designed to withstand the power from a supercharger. You will need a 4t65e-hd or 4t60e-hd if you want it to last a while.

Also, putting 8 lbs of boost or so in a 9.5:1 engine will cause all sorts of heat and knock. The engine itself can take the abuse, but you will have to change quite a bit of things around.

Better option for that engine is a CSC or a turbo.

the l67 has stronger pistons. the head on the L67 (series II) houses the fuel injectors, while the N/A folks have it on our lower intake manifold.

but the largest concern for me would be the pistons.

Pretty much if u want to try and attempt to apply a Supercharger on a N/A 3800, get ready to start replacing some main internal parts, like pistons and rods. And as Sol pointed out, the tranny is key when having boost in a car. Especially when your putting a large supercharger in, say in like a viper, but were not dealing with vipers here. Just get ready to dish out some money to replace parts after the start blowing from the boost.

I disagree completely, Unique. This'll end up costing so much time and effort, that a simple full swap of an L67, trans, wiring harness, and PCM would be far cheaper and easier.

Disassembling and re-building with L67 or beefed up internals is NOT a smart way to tackle this.

they have series 2 */c engine, tranny and pcm on ebay all the time, that would be a good route there, or maybe a junkyard...

i don't really want to supercharge this motor on my sse.i'm kind of a little old school when it comes to motors i'd really rather do pistons,cam,port polish heads and the like but i was really wondering what you could do with the sse motor this way.i haven't messed with these sixes most of my rebuilds were chevy 350s.if the trannies in the n/a cars are weak what is the highest hp to ft/lbs of torque that you can go before you wipe the tranny or torque converter.also is there any performance intakes throttle body injector kits or parts.what is the valve size and cc difference between n/a and */c heads.sorry for all the questions but i really like these cars and i would like to be able to smoke some of these rice burners in my family grocery getter.gotta LOVE THE CREEPER SLEEPER!!!!

There are a ton of performance parts available to you from INTENSE. Rockers and a PCM would wake your car up (just ask Smellbird). If your serious, you can get heads, cams, etc...and make some decent power. The fastest N/A 3800 is making 219HP at the wheels and has a pb of 13.5 in the 1/4. Thats not much slower than my moderatly modded boosted car but it has a shitload of stuff done to it.

How did they achieve a 13.5 in the 1/4? is the motor in a tiny car?

I believe it'* in a GP GT.

And it makes TONS of torque. That is the key.
