Hey guys, I need some help.

I found a 2002 3800 na rebuilt with 0 miles in a fiero. The thing is, I really want a sc engine and not a na. Would it be wise to go ahead and get this or just keep looking for a sc engine? Im sure there is head/piston changes between the 2, but figured I would reach out here.

With 0 miles on it, get it, put SC top half on the NA long block and enjoy it.

Turbo is even easier than supercharging!

I have the n/a, and no need for the sc. It's plenty fast, just not stupid fast.

So other then the supercharger, what is different between the 2 engines? Heads, pistons?

The bottom end is a little stronger in the SC motor.

I purposely built a NA, used a 0 mile rebuilt motor (great deal, original owner's project fell through), and have ZERO regrets. Turbo is always a future option if you need more.

No doubt! 205HP/230TQ in a Fiero is going to be a fun drive.

I'm looking for a 3800sc but I don't have a ton of money to spend. I'd rather have a supercharger than a turbo, don't like the turbo lag. But my stock 2.8 has a lot of pull so I guess I can wait till it's tired. Or if my supercharger itch gets so bad I have to scratch it.

I used to be one of those turbo lag guys. I was use to turbos from the 80's cars. Now days its very very minimal! from what I experienced with my cobalt.

going na doesnt limit you with 0 miles why not?

Well since it seems like the engine is not as stout as an sc engine I'm going to keep looking. Plus the rebuild was with all stock parts, which I would have to change out.

If you are planning on swapping in a 3800sc series 2 later, do that zero mile 3800n/a series 2 now...

1. Wiring harness will be identical except for the plug on the MAP sensor and the SC uses a boost bypass solenoid (that most people don't wire)...
2. Mounts are the same...
3. Coolant routing is the same...
4. Fuel routing should be close to the same... Make sure to put in a fuel pump that will accommodate the SC motor later so you don't have to drop the tank again...
5. Exhaust dumps in the same place...
6. You will need a new PCM programmed for the 3800sc motor

Basically you would drop out the N/A and throw in the SC when you find one... but enjoy the benefit of:
1. 58% HP gain
2. Still run 87 octane
3. Better fuel economy
4. ODBii (I run TORQUE on my phone)

I am working on a 3800sc for my other car, but use my 3800n/a as a daily driver...

EDIT: I guess that it all depends on the cost of the 3800n/a motor. You could always turbo it like everyone says...

Isn't it strange that after a bombing, everyone blames the bomber, his upbringing, his environment, his culture, his mental state but … after a shooting, the problem is the gun?

Speaking of that torque app, which adapter do you use?

I've tried a bunch of adapters and will no longer buy any other bluetooth adapter other than BAFX ELM327 with the blue label. Search amazon it's like $25 or something shipped.

If you use the right turbo, you can have full spool just off idle and maintain a torque plateau to redline. It's a matter of matching the size of the turbo to the size of the engine. A big turbo with a high, dyno-queen horsepower number won't spool 'til near redline. But a tiny turbo too small for the application will hit full spool at idle and will putter out halfway to redline. If you do it right, you could have an engine with the output similar to the 2.0T in the Sonata/Genesis 2.0 (second version) that did 274 horse at 6000 RPM and 269 ft-lbs of torque from 1800 to 4500 RPM. (Yes, a 2700 RPM torque band and a 4200 RPM powerband.) My 2011 Sonata SE Turbo was a crap car when it came to electrical reliability, but that little 2-liter really did put out that much power. The L36 can do that and much more with the right turbo.

There's a reason that some of the fastest L67's and LSJ's on the road simply gutted the superchargers and replaced them with turbos. Just sayin'.
