No this is not a topic about Mortal Kombat, just thought I would try and get some attention for my next topic. I have been slowly improving my 97 Z24 2.4 Twin Cam Auto and I'm ready for the next big upgrade. I have decided to first buy my fiancee a car and park my Cavalier in the garage. So I can pull the engine and rebuild it from the ground up(128k miles). I want to build the car for a mild 1/4 car and still make it street drivable so I can make it my Sunday cruiser. I'm wanting some help with ideas, not sure if I want to boost or stay N/A with a shot of Nitrous. But for sure what I'm going to do is this:
ARP Main Stud Kit
ARP Head Stud Kit
Competition Intake & Exhaust Valves
3 Angle Valve Job
Eagle Forged H-Beam Connecting Rods
Wiesco Forged Pistons
Secret Cams
2.3 HO 086 Head
2.3 HO Oil Pump
62mm or Bigger TB
Unorthodox Ultra S - Lightened Underdrive Crank Pulley
AEM Power Pulley
Yank High Stall 3k Torque Converter
HP Tuners (If needed)
Chevy Blazer Fuel Pump
Bigger Fuel Injectors (size??)
NGK Tr6 Spark Plugs
I'm also going to get a rear disc break conversion, not sure if I want to use the Neon swap or go with a BAER kit. I'm pretty happy with my suspension as of right now KYB AGX and B&G 1.6" spings. But If I see needed I'll upgrade to Koni Yellow's with Ground Control Coilovers. Here are the upgrades I have done thus far:
Upper and Lower RK Sport Motor Mounts
B&M Shift Improver
2.3 HO Intake Manifold
2.3 HO 56mm Throttle Body
WAI & K&N Cone Filter
Pacesetter 4-1 Header
Catco High Flow Catalytic Converter
2.25" Compression Bent Cat-Back
High Flow Muffler
KYB AGX Adjustable Struts
B&G 1.6" Lowering Springs
Megan Racing Front and Rear Tower Strut Bars
That is my list of upgrades so far, so like I said not sure if I want to turbo or stay N/A with like a 50-75 shot of Nitrous. I would be really happy if I could hit around the 13's in the 1/4 with an auto. Throw some other parts I should upgrade out there or give me some more ideas as to what to do. I want a strong engine that is what is most important to me. Thanks ahead of time to everybody that helps me.

Nobody have any ideas? So it sounds like a pretty good build right?

im not a real big fan of underdrive pulleys, i like electronics though
1989 Turbo Trans Am #82, 2007 Cobalt SS G85
I didn't see any gains with my underdrive pulley, but Mike Davis has a couple of Crank Pulley and Alternator pulleys, he gained 8 hp on the dyno with those two alone!
NEW SIG COMING SOON FOR 07'!!!
I like my a/c, and my friends underdrive underpowers his power convertor, which makes laptop use (and LM-1) very limitied.
with that head you are looking at some serious compression IIRC,
personally I would scrap the pullies, the nitrous, and larger throttle body, and invest that in a cometic head gasket, and get HPtuners Pro for sure, that is a must when tuning for power. as far as a turbo setup goes.. how would you feel about an intake manifold that would fit a M62 or m90... I will be making a prototype in 12 days when I get home, and might make a couple, (or more, the more that I make, the cheaper they get) but a friend will get the first one.

I think you really need to decide on what you want nitrous/N/A, or boost before making the list. It it is a track/Sunday cruiser I say boost. I personally love underdrive pulleys and have never had any issues with running them. Not sure why some would say scrap the TB either.
FU Tuning
Yeah I'm wondering why I should scrap the bigger TB? I thought with the bigger TB I would get better top end. I mean yeah my 56mm is a decent improvement over the stock 52mm. And every time I ask about the light weight stock pulleys that MD-LD9 made he is out of them. And I will NEVER deal with RSM... With my list of things I want to do, I know no matter what I do in the end I want a strong engine no matter if I stay N/A, boost, or nitrous. So I know I'm going to at least get the forged pistons, rods, ARP Studs, Secret Cams, and probably a valve job with intake and exhaust valves. I would say at the moment though I'm leaning toward Nitrous. I have been reading up on both turbo and nitrous and kind of like nitrous better, I can use it when I want (track only), and with using it less my eingine will last longer between rebuilds, and the number one thing I like is the cost to power gain ratio lol. But I love turbo, probably more for the bragging rights and the most beautiful sound in the world a BOV
lol... So in the end I'm probably just going to build a strong engine and throw a 50 shot NX wet kit on it.
So after saying all of that, with setting up a nitrous system on it that is capable of maybe if I'm daring some day pushing it to a 100 shot. What should I add and what is not needed for what I want. Keep the posts a comin!

Well let me say if you build a good motor there is no reason to only run a 50 shot. If done right a 100 shot can be done on a stock motor, so a nicely built motor could hold more. SpeedRacer just posted dyno numbers from his lower compression motor (still n/a) putting 171hp. Up the compression on your motor somewhere between 10:1-11:1, nice head work, TB, pulley, nice header and exhaust, some tuning easy 200whp all motor car, and then start playing with the juice.

That is my dream to have a 200whp N/A 2.4 Auto. If I can get that I would be happy as a dog with a new bone
.

Ok so I have been doing more searching and reading up on the site in diffirent forums, and came up with this new build. I would really love to get a 200whp Auto 2.4:
ARP Main Stud Kit
ARP Head Stud Kit
Intake & Exhaust Valves
3 Angle Valve Job
Eagle Forged H-Beam Connecting Rods
Wiesco Forged Pistons
2.3 HO Oil Pump
Secret Cams
Yank High Stall 3k Torque Converter
Chevy Blazer Fuel Pump
Bigger Fuel Injectors
HPT Pro
NGK Tr6 Spark Plugs
Light Weight Stock Crank and Alternator Pulleys
ZEX or NX Wet Kit (30-75 shot)
I don't think I'm leaving anything out. Now the way I understand is if I get a wet kit I won't need to upgrade my fuel system. But If I'm going to be upgrading so much more I'll need the better fuel upgrade's right? Now what size of injectors should I be looking at if I should upgrade fuel 310cc? So is 200whp N/A possible if I build the engine up with this list? If not what else should I be looking at?

You forgot the 086 head this time.
Josh,
If you go with w41 cams instead of secret cams, you can do 200whp N/A easily (I would guess between 210-220). I hope to get the car running soon, and I will try to get it dynoed so that I can give you my numbers.
On a side note. I noticed that the car reved faster with the aluminum underdrive pulley. I had read before that you should expect low end power gains, but my butt dyno only felt it on the top end. I really hate that the headlights dim at idle rpms though (it is fine when crusiing). I noticed there is an aluminum one being sold on ebay that says it is stock size, but it looks identical to the one I have-
click...so I don't know what to think of it.
What if I stay with the stock 2.4 Head and go with the secret cams? Would it still be possible to hit 200whp? And I don't trust anything off of Ebay.

And if I am able to find w41 cams would they work with my eingine on the OBDII without throwing codes??

I started a thread similar to this,
clicky, i want 200 hp on a manual without juice.
It would be a lot easier with the 086 head, and that way the HO cams fit the towers. Although I read the HO cams wont work on OBD II without a standalone, was written in 2003 so i dont know if HPT would change that, but the w41 cams are more agressive so....

Thanks I understand the 086 head much better... But still lost on the whole CR...

Are there any direct replacment oil pumps that flow better than stock instead of the 2.3 oil pump? I guess if no then i will have to go with the 2.3 ho oil pump. Just wondering trying to cut down on so much moddifying on the 2.4 block.
My car has two speeds, fast and faster.
And does anybody know if HPT Pro will cure the CEL on OBD II if I get the w41 cams?

I really hate it when people put "FIGHT" in a thread and its not in the anything goes or war forum.
For all the money this is going to cost you just turbo the engine.

What did you just feel like putting in your 2 cents? Did that make you feel better that people know your opinion now? Do you know what I hate? People that post on a thread that has nothing at all to do with the topic. But you don't see me going around complaining about it.
My car has two speeds, fast and faster.
as far as i know, its impossible to get a oil pump that will flow as good as the 2.3l one.
so do the 2.3l oil pump swao. btw the pump doens,T need to cme from an HO, all 2.3l share the same oil pump.
new pump only, if you wanna see the swap pics, I am not sure who made them but I still ahve them in my email.

yeah, better off getting a new one. part number for a melling pump is M136. check on ebay, there is one at 129$ bin and one on auction....
Yeah can you email the swap pictures to me? I think you tried once but nothing came through. Or can you post the pictures on here or make a new thread for the 2.3 Oil Pump swap? If there is enough detail to it maybe it can be made a sticky?

ok man, this is gettin FUKING LAME
just send me back the manifold

Actually I did answer your question. Your better off putting on a turbo for the amount of money you'll be spending. No point in burning out your engine with nitrous when your engine will be more than capable of handling a good bit of boost, you'll maintain streetability because your not lowing compression and you'll be able to pour on the power when you want to. You titled this thread for attention and thats what you got.
