I haven't decided if I want to turbo my ecotec or not. I am, however, going to do everything else. My question is if I use the following parts, does anyone have a rough idea of how much HP I'll be running. Also, is there anything else that would need done in conjunction with the following:
Stock head gasket (24444091)
Stock head bolts (11518066)
Stock Piston Rings (21018813)
Performance Connecting Rod
Performance Forged Pistons
Street Performance Wrist Pin
Adjustable Cam Gears (88958613)
Bates Engineering Valve Spring kit (ESGV0002/0150/0065)
4340 Forged Crankshaft w/ timing ring (2237245765R)
Ported Cylinder Head (88958619)
High Performance Cam Set (88958636/37)
Aluminum Intake Manifold (88958629)
Neutral Balance Shafts (88958615)
(####) are the part numbers. If you guys can give me any info it will be much appreciated. Also, if the above list isn't specific enough, let me know. Thank you.
Also, I am running this on the 4T65-E transmission. GM's "guide book" doesn't say that it can't handle it. It doesn't exactly say it can either. Does anyone know the HP capabilities of the 4T65-E? How much HP can it handle stock? What upgrades can I do to it to handle the above upgrades?

no one can tell you exactly what you will be running and if you dont turbo then you certainly dont need the aluminum log style im. even if you do turbo, i would suggest getting an im from a 9-3 turbo saab 2003+ i think unless you plan on going with a butt load of boost(20+). with the log style you will have to move the radiator forward(lots of fab.). good luck.

I actually wasn't expecting an answer to that question. More so the main question: Is there anything else I should do or anyhthing I shouldn't do.

Joe, I see you got alot of that stuff from GM Performance. I wouldn't get everything they have...I'd steer more closer to aftermarket companies, less money and better products (in some cases).

If you're making a high horsepower motor, you should steer away from the stock head gasket and go for something stronger. Cometic makes a Multi Layer Steel (MLS) Head Gasket for under $100 I believe. Same goes with the head bolts, you would want something stronger. ARP makes studs for the ECOTEC motor that are inexpensive.

Performance Connecting Rod
Performance Forged Pistons
Stock Piston Rings (21018813)
The reason I would say stay away from them is because there is no type of rating on them and GM provides very little information on them. I am highly inclined to believe that the Rods are really the LSJ rods (LSJ motor = 2.0 ECOTEC motor) which are forged but not as strong as say a company like Eagle would provide you for the money.
Overall, Pistons...go Wiseco or JE. Rods, go Eagle...period.
BTW, if you bought any of the Wiseco or JE pistons, I'm 97% sure they come with Piston Rings.

4340 Forged Crankshaft w/ timing ring (2237245765R)
Not sure if you knew this but that is an Eagle Forged Crankshaft.
I had stated in the ECOTEC Build Guide about the whole situation with getting another crankshaft if you're doing a motor build...
ECOTEC Build Guide wrote:Crankshaft: The stock ECOTEC crankshaft has been tested to handle power amounts up to 600 HP. If you really want to swap your stock one out, you have the option of 2 crankshafts...Eagle's Forged Crankshaft or GM Performance's De-stroked Crank shaft.

High Performance Cam Set (88958636/37)
Find out the specs on those camshafts and see if that's what you need or more for what you're aiming for as far as RPM range & Powerband. I personally would stick to companies like JBP or Crane for camshaft sets.

Aluminum Intake Manifold (88958629)
That manifold is for HIGH horsepower vehicles. It's a log style manifold and is huge. You have to fit an LS1 Throttle Body on there (75 MM). They use those on the drag cars. In order to even fit it, you would have to move the radiator forward. I don't think that is something you're necessarily looking for.
If you really want or need a manifold, you can try what I am doing when the time is right. Get a Saab Manfiold (off an 2003+ Saab 9-3 2.0 Turbo ECOTEC motor) and have it ported. It's a direct fit. I will be attempting this after my turbo setup is finished and display pictures and let everyone know if there were any type of gains etc etc.

Neutral Balance Shafts (88958615)
Not sure if these are necessary or not.

Bates Engineering Valve Spring kit (ESGV0002/0150/0065)
Ported Cylinder Head (88958619)
If you want an upgraded head, I would buy an pre-assembled head package that is already ported and flow bench tested. I touched upon this in the ECOTEC Build Guide as well...
ECOTEC Build Guide wrote:Port & Polish Head Packages:
There are basically 4 companies that you can get these from, Patriot Performance, GM Performance Parts, Jbody Performance and RSM Racing. They offer the springs, retainers and port and polish the cylinder to a nice amount to give your motor a nice breathing path. If you want different valves, those are usually extra and you'd have to get a price on those. I personally have the Patriot Performance head and noticed MUCH faster reving and top end power. I would also suggest getting a fuel tuning after this is installed to make sure you are running the right fuel amount.
You can also consider a full Race Head package available by Jbody Performance. Their package includes a 5 Angle valve job, titanium or stainless steel valves, HD custom valve springs, all new seals, with computerized flow bench data sheet, cam gears and even Pistons. Read can read more info at their page http://www.jbodyperformance.com/new/PartDetails.php?partId=302&catId=302&catName=JP0302
Patriot-Performance Stage I Head (Assy) - P/N: 2039 - Price $1,095.00
Patriot-Performance Stage II Head (Assy) - P/N: 2042 - Price $1,295.00
GM Performance Parts Ecotec High Performance CNC Ported Head - P/N: 88958619 - $1,334.38
RSM Racing Ported Head - P/N: PH22EJS3-0304 - Price N/A
Jbody Performance Race Head Package - P/N: JBP0302 - Price $2,519.28
Now just a final note, I'm guessing alot of this stuff you got from the GM Performance Book where it says "How to reach X Horsepower" and at the end of each chapter it says what parts are on the motor etc etc. When it lists those parts, it's saying what parts you can use or get away with having (in cases of having stock parts left over) to still reach your HP goal. Now, rule of thumb when it comes to modifying a motor, if you have it apart, why keep the stock parts? Know what I mean?
Also, some of the parts like the Pistons and Rods are limited to power but they don't list that to you. If you go to the next chapter, they change the pistons and rods to a different set because they are a higher rate of forged pistons and rods. Basically what I'm saying is if you have the opportunity to put strong pistons in replace of your stock ones, why not put the better ones in for the money?
Alright...I'm done rambling lol. If you have anymore questions, you know me, just ask.

They actually say to use eagle or manley connecting rods and wiseco je or diamond pistons.

forget neutral balance shafts just remove them period
it is a noticeable gain with this mod though
The one, the only, ME.
