Supercharger or 2x turbo for LS. Would a local shop be able to do it?

[b34nz]

I have exhaust (custom 40 series flowmasters), intake, modded cold air tube from lower grill, and the XCal2 and when running at max tune I'd be surprised if I made more than 280HP. That is a 30+ overall HP gain from my stock 252 on the gen1 LS. If you don't SC or some other form of forced induction it doesn't get too much faster. That is just my opinion, I'm not an expert by any means though...

My next mod is 3.58 gears. If I was going to go any further I'd get nos. A 50-75 wet shot with all necessary safety accessories used with care and common sense would be fine...

From what I understand things like headers, throttle boddies, intake manifolds, and other things similar are too difficult and costly. First off you don't have much room and second you would need all the parts custom machined (to my knowledge)...

Also, if you only need/want the power 25% of the time nos makes WAY more sense than a SC or turbo....

I really want to get a S/C =[
But after thinking about it, I dont think I'd spend more than $6,000 to have a S/C bought, installed, and tuned. It's just too much money.

So spend like $500 and get that nos kit used and add 50-100 hp...

Whether you feel like it is cheating or not, nitrous is the best bet for you in this case. Besides you actually saying you want nitrous, the rest of your preferences point right towards it.

I don't view nitrous as cheating at all. It is just one other way of adding more air to the mixture to make more power. No it is not on all the time like a turbo or a supercharger would be but that is the beauty of it. If you want to go back to a relatively mildly modded car then you can do so with the flip of a few switches.

I like it because when it is off I can run a low low 14 and with it on I will run a high 12. It is horsepower on damand and only when I want it. And of course in the shirt run NO2 is one heck of a lot cheaper than a turbo or supercharger. just pointing out some other facts man. It is your choice and yours alone. We have armed you with the knowledge, now go out and do whats you feel is best for your situation.

I agree, I don't see nitrous as anything other than another power adder. People don't realise the tuning that needs to go into nitrous also, which is one of the reasons it gets a bad rep for blowing motors. A little word of advice, run copper plugs when using nitrous.

You will need an awfully big shot to take 1.5 - 2.0 seconds off of your 1/4 mile.

Nitrous got a bad rep because people did exactly that back in the 70's. They put it on their cars and didn't expect to have to tune for it. Big booms later and now that whole generation has been mostly spoiled with people badmouthing nitrous. Now THAT generation is in the positions such as Ford tech advisors and the local mechanics positions and tell other less understanding people the bad things nitrous will do to engines. Tune for it and run the right stuff and you will be fine.

BTW, on the copper plugs comment I will say this. Dont ever mistake changing plugs in an LS for fun. I went with 2 heat range cooler copper plugs in my LS and it was a PITA to access the rear bolts on the COP covers.

I will only need to be taking 1.2 seconds off my 1/4 ET to hit 12's. My current N/A setup has at least a 14.2 and maybe a 14.1 in it on a good day. Then from there it is just a little over a second away to hit 12's. While that is obviously no small margin, a progressive controlled 100 wetshot will get the job done, and with decent traction too.
