And we've seen how far people are going with a supercharger...

What are you trying to do? Are you going n/a or forced induction?

You keep talking about strength but strength for what type of stress?

I'm confussed on what you're trying to accomplish.

 

Does JBP Do Custom engines ? Can I tell them What I am looking for and will they build it?

thanks

Leo

Upgraded supercharger of course!

 

To what supercharger?

 

Yeah, I'm starting to get confused now as well.

 

Atleast I'm not alone...

 

I guess he wants to do a blower swap? But to what?

 

OK, let me start again.

I want to build up my internals to achieve my 300-350 WHP Goal I will be or may reuse my GMPP STAGE 2 once complete or upgrade to a totally different type of supercharger. But the fact of the matter is I just want to focus on the ENGINE INTERNALS ONLY! LOL

Now, Are there aftermarket companies that produce HI-PO internals (Far superior to stock)
for the LSJ that WILL help me Acheive 300-350 HP

I want to do A FULLLL OUT ENGINE BUILD! totally from top to bottom.

PISTONS, RODS, CAMS, ECTTTT. THE WHOLLE NINE YARDS FOLKS

are there aftermarket companies who produce these products for the LSJ 2.0 and could i please have the name of the companies so i could do some research on the products,

Much Appreciated,

Leo

P.S. SORRY FOR ALL OF THE CONFUSION

 

Ok well...

With a Stage 2 and a "built" engine...you won't achieve what you're trying to aim for.

- Raising the compression would just achieve a higher combustion chamber temperature, need for more control with fuel and more than likely will knock MUCH easier.

- You still have a low flowing supercharger even with a Stage 2 pumpin out whatever PSI of air pressure it does.

- Valvetrain changes would be the more positive side of you building the engine, you'll be able to flow in more air per intake cycle (and more exhaust out as well if you're having the exhaust side ported as well).

Your stock engine is more than capable of reaching that amount of power BUT you have to remember that it's the type of forced induction, the efficiency of it and the amount of airflow (CFM) it's going to flow to achieve the amount of power you're trying to achieve.

You are thinking WAY too much into the engine and not into your main power adder. If this was a n/a motor build, this would be a totally different story but it's not. You're trying to maintain control over your f/i unit and have it to be strong enough for the stress that it can cause.

 

I need your help folks, for this build, need to know what type of aftermarket internals are totally rock solid pieces for this build. Worst comes to worse i can always ship the engine to my local enngine guy.


Lets say i do a built engine with stage 2 or maybe even upgraded blower the only focus would be cooling. and there are tons of ways to let that engine run cold

 

I gave you links to GM's website and everything you would need. I also gave you a link to reading that shows you how they made 300. If you want to go about it this way, I promise what I'm telling you right now is the perfect way:

-High compression 10:1 pistons
-They have billet rods and crank if you really want it but our bottom ends can deal with 400HP+; the stock rods and crank are FORGED STEEL
-P&P heads with full exhaust including headers
-Valve springs
-Cams to match engine
-Dual pass plate

This engine will make it's power using higher RPMs. Our crank can take it, our rods can take it (Unless you want to make over 400WHP do not worry about it at all). Our roller rockers can take it; the stock headgasket can take it. You may need headstuds. Read GMs build guide and then customize it to your liking.

I'm just trying to make my point a little better with the caps and what not, not to be an ass. Plan on spending around $3,000 to build a similar setup.

Edit: http://www.crateenginedepot.com. You can buy the components here.

 

Ok, I think you just want to build the engine so that after its fully built then you can look into changing your supercharger? And just run stage two until you do so?
I dont know much about the internals, still kind of a n00b here, but heres a link to a vendor's site, and its the engine parts page:
http://www.cobaltperformanceparts.co...dex&cPath=1_18

Diamond racing pistons, valves, springs, I saw all that kind of stuff here. Is this what you are looking for, so that you can just research?

 

Plus i will be porting & polishing the heads, maybe even bore the heads. I need the built engine if i'm gonna upgrade to a bigger blower, cooling is going to be another challenge all on its own, once i build it i will make sure that this engine won't run HOT!.. lol

Now let's talk internals! where to buy and from what company?

thanks

Leo

 

Good post

SSGX, Keep in mind I am using the GM parts and guide as an example. You can do something similar but purchase the parts from elsewhere to keep costs down a bit.

 

thank you very much! greatly appreciated

Leo

Thanks alot my friend Really appreciate it.

Leo

 

Keep in mind that going with the larger blower will be a completely custom build. It's going to cost alot. Just thought I would let you know.

 

Regardless of cooling...

You need AIR to spary more FUEL to cause a stronger ignition to make more power. Cooler air will be denser and have more air molecules but that only goes so far. You need a sufficient power adder or type of forced induction.

Like I said, you're focusing too much on "omg it's strong and built" rather than what I am using to help withstand the stress.

Custom Manifold

Alot of money for a more efficient supercharger unit alone

Having it line up with the pulley system properly

 

I agree. On top of that, the larger blower will have higher parasitic losses, weight will go up. And with all of those problems comes the fact that you will be customizing a intake plenum, belt, etc. etc.

SSGX, I just don't think it's worth it, but definately do what you want. If your goal is to make a shitload of power using only modifications which will strengthen the engine etc. then I recommend nitrous.

Edit: Haha, you posted that as I was typing the same thing

 

I think you may need to help out the others who are waiting on the twin screw from TAG and light a fire under their asses
Sounds like you will need that kind of swap to get the power that you are wanting to get to after you have built your motor up

Once again, please note, I am still n00bish, so.... grain of salt

 

Grain of salt indeed sir j/k. The larger blower will not produce that much more power as I believe he's talking about a larger roots. Although the twin screw will make alot of power it will be very expensive to make his own kit. If he made it right however he could sell it to TAG.

 

If the TAG kit was finished though, that might be a good swap to do what he wants, right? or am I totally on the wrong track here?

Post 1000! ROCK!

 

Well folks, i'm still kinda undecided on weather or not to even swap chargers, i spent money on my stage 2 kit i might as well re-use it. but heres what i think i'm gonna do;

Diamond Racing Pistons 10:0.1 Compression

Ferrea Valves

SuperTech Titanium Retainers & Stainless Spring Set 94lbs

Port & Polish Head bore it out

I'm missing connecting rods though, need to find a supplier for heavy duty connecting rods.
Then i'l just pop on the stage 2 and do a bunch of cooling mods
twin intercooler lol

what do you think.

 

Oh yeah, that would be a nice swap. He could definately do what he wants with that setup.

Don't forget the cams

The connecting rods can take the punishment, they are forged steel. But, if you want room for expansion some stronger rods would never hurt.

The "Port" on the P&P is the process of enlarged and smoothing the ports by machining.

Edit: It will be a must to get a really good tune.

 

Oh yes lol my mistake Cams, does eagle make rods for the 2.0 LSJ?

then I will be able to DANCE!! with the big boys!

lol

 

The rods can take the power you want to make, but if you have the money and want to then do it. I don't know if eagle makes rods for the LSJ. GM makes billet rods for the engine. Did you read the 300+HP article by GM? They have some good tips in there about pre build preparation such as deburring rough castings etc.

Edit: Eagle makes rods for the 2.2L Ecotec. They are different in length than the LSJ's.

 

Could i Go Custom?? Custom is always better

Thanks,

Leo
