Basically Im looking to do a few upgrades as far as horsepower is concerned, came across this kit and was wondering if this is a good starting point for a nitros kit. Not trying to do to much just looking for a convenient boost here and there, plus this is my first time to purchase a nitros kit. I have a '05 SS/Supercharged Stock.. (1.) From reading the description will I need to buy any extra parts outside whats in the kit?? (2.) Does this seem like a good kit to begin with? (3.) What other alternatives would you suggest (if any) that lies under the $330.00 price range.. Thanks for help- link below http://www.jegs.com/i/Barry-Grant/132/10010A/10002/-1 p.s. im looking to get the "entry level" version

 

That kit will not work for your car. It's designed for carburated stuff. You are going to want to do a few things before spraying nitrous, too.

- You need spark plugs 2 heat ranges colder than stock, gapped tighter than stock for our application. You'll want copper core plugs. Autolite 104s are a good choice- the gap size depends on what size shot you spray. Speaking generally, if you're spraying below 50 HP, a .050 gap is OK. 50-75 should be around .045. Above that and you'll need to gap tighter.

- Nitrous creates a ton of cylinder pressure. You're going to want to do at least a bit of exhaust work before spraying. A 3" downpipe would be enough for your average "street sized" shot, provided you're on stock boost levels.

- Make sure your car is in an excellent state of tune (fresh filters, clean sensors, good fluids) before you install your nitrous kit.

OK, once you have that covered, you need to find a kit that works with your fuel injected car and adds fuel when spraying. The Zex dry kit made for our cars (http://www.zzperformance.com/grand_p...=462&catid=109) is my personal preference. It comes with three nitrous jets that let you pick a 55, 65, or 75 hp shot. The kit adds fuel while your spraying by intercepting the vacuum to your fuel pressure regulator, and spiking fuel pressure while your on the spray. It's a very reliable method of safely increasing fuel while spraying.

I'd recommend doing some serious research into how nitrous works before taking the plunge. Nitrous is a GREAT way of making big power for cheap, but there is plenty of stuff to take into consideration. You do NOT want to "cheap out" here. Good luck.

 

appreciate the advice, it really helped..

 

No problem- hope to see you spraying and running some low ETs in the future. Some Regal/GTP guys are going low 12s with just bolt-ons and nitrous- nitrous makes our cars very potent when done right.

 

If you want my opinion- then completely forget about nitrous for now. How much power do you really want to gain? If you were just looking for that 75hp shot; you can easily achieve that with cheap, easy bolt ons. It will cost a pinch more, but you won't have to fill a bottle- and you will have the power on tap all the time. I'm not trying to say this to go against those on the bottle- spray is a great way to make power; but with a stock L67, you're sitting on tons of easy, untapped potential.

Here is what I'd do:
-CAI/FWI (can do a FWI w/ a cheapo cone for under $40, or under $70 with a K&N)
-3" DP & cat delete (I picked mine up for $100 shipped)
-1.9 modded stock rockers (I got mine for $225 shipped)
-180* thermostat $5
-Autolite 104 copper plugs (like $1.50 each)
-Front powerlog (I got mine for $100 shipped)
-Tune (canned tune runs about $100, custom can be free/cheap from a local club member to $300-400 for a full dyno tune)
-3.4" or 3.5" pulley (I got mine for free doing a pulley swap for a buddy, I've seen them go for free + shipping online; usually run about $20 shipped or so)

That should put you about 300 crank horsepower instead of 240; but you'll always have the power, never worry about leaks or sticky solenoids, and you'll be near stock reliable.

Thats just my opinion though...
