Hey, I just have a couple questions. I was thinking about putting in wiseco pistons (.040 over), Eagle Rods, and new camshafts. I am going to get my head ported also and new valves too. My questions are:
1. What is the better head gasket I should use? Is Cometic good?
2. Are there any other pistons out there better for the price?
3. What camshafts would you choose. I havent had much luck finding the right ones.
and last but not least.... Since I am doing all of this to the engine, do you think there is anything else I should take care while it is out?
Thanks alot guys.

.make sure sum1 is nearby to tune your comp.
.2.3l oil pump or get your crank ported.. if you want your main bearings to last....
.make sure ALL your OEM stuff is Solid..
.check your fuel pump.. replace if needed.
.suspension.. .....
.ttr has some wicked engine mounts.. check them out..
i have them installed, they rock.
.tranny work.. tranny work.. tranny work..
.if you go forced induction.. get an oil cooler.
.try to find a more efficient radiator.. cooler the better.
.ppl say oem cv axles wk fine for 300hp.. but idunno......
.jbp is a nice place to see what you could need 4 build..
i cant find you a better headgasket.. responding on ps3
.. but you can never go wrong with a higher quallity one.. make your weak link your valves.. or your crank.. instead of .. blowing a gasket...... weisco pistons are good.. jbp stage 2 cams are good.. exhaust porting is good.. leaving your crank how it is??? i have a 2001 2.4l /w 4spd.. my last motor.. efed main bearings.. from oil starvation... good luck have fun

^ Not a lot of good info up there...
You don't need your ECU tuned to run just those mods you posted.
And Chase has posted this twice now.... WTF is a ported crank? The crank doesn't have ports... how would you port it? I searched google for 20 minutes for "ported crank" and the only thing that came up deals with RC engines...
The stock crank is GOOD to well over any horsepower you make, PROVIDED you tune it correctly. A big enough detonation will probably destroy your pistons first, but could snap a crank at high HP/RPM's. Also, the main bearings are not a problem on the 2.4's, its the rod bearings from oil starvation, which is why a lot of people switch to the 2.3 pump, its something to think about.
Try comparing the JBP "Stage 2" cams to the secret cams... then save yourself some money and use the secret cams.
The valves are not a "weak link". They will flow just fine to over 300hp.
Tranny is fine if you are just doing what you say you are, if you are adding boost or nitrous, then think about the tranny, but its fine.
The fuel pump is fine, I'm running mine to 250+hp and 280ft-lbs of torque. The goal to getting the most out of ANY fuel pump is to size the injectors correctly.
Your radiator is fine, unless you are making some major hp numbers, the stock radiator takes care of business.
JBP is nice and all, but show me one happy J-Body customer who got what they wanted right out of the box when it came to their engine builds.

Buy stuff from CarCustoms Ebay! Won't be disappointed!
I agree with what shifted wrote.
The only other things I would like to add is that if you install new cams you need new lifters. Also you you should replace or at the very least have your valve springs tested. When I put cams in my car I went with the secret cams. I bought the intake used since you can not buy them new. The intake cam must be from a 1995 2.3 liter. I bought the exhaust new from Autozone. Just a litle FYI the price of cams, new lifters, and new springs was almost 600 bucks right there.
I myself strongly reccomend the 2.3 oil pump swap as that seems to me to be the weakest point on our engines or atleast it was on mine. Shifted was right it is the rod bearings that get starved for oil not the mains.
I do not know what kind of price you were quoted on the pistons but they are about $550 for a set. I do not think anywhere else even makes pistons for the 2.4. Do not worry though wiesco is a good brand and a reputable company. They are quality pistons.
As for the head gasket. I do not know what your plans are as far as boost or NA. I recently read about SCE making copper headgaskets for the 2.4. You might want to look into that.

I've reused my stock lifters with my Secrete cam swap, never had a problem (on my car 30+k miles, and a few other cars I've done the swap on. The paranoid get new lifters
)
JE, Wiseco, and Venolia make pistons for the 2.4
Cometic makes a Boost and N/A MLS gasket for the 2.4. SCE has been making their standard copper headgasket for years, but is a PITA to use. Not sure if they ever made their Titan gasket for the 2.4.

so.... If I were to go with the .040 over pistons, eagle rods, secret cams, p&p job, 2.3 oil pump, and forced induction...what do you think my weak point would be... I guess I should replace all springs and bearings too... right? Where else can I get more power out of that engine w/o blowin somethin up....?
When I break something..... I'll tell you what my weak point was.....
Right now, its going to be axles or trans........

Excuse me.. i meant to say oil galley porting..
there is such a thing. also where i live.. most of the cavs died because of a blown head gasket.. and the sensor didnt go off til' it was too late... cooked bearings... i still think it would be a good idea for oil pressure and cooling..

For the parts that you're talking about replacing (pistons, bearings, gaskets, etc.) I'd suggest maybe you just look at the
engine rebuild kits offered by importperformanceparts.net. You'll get all those parts together in one package - I haven't shopped around to check the price and see if it's cheaper than buying separate so maybe it's not the best deal out there, but just wanted to point it out (it's $999 with pistons, rings, wrist pins, bearings, gaskets, lifters, and a new OEM timing set). Although if you're looking to boost, the only two options they have listed are 9.5:1 and 10.5:1 CR. Maybe you could contact them and get them to go with 9:1 pistons.
And what's this about the secret cams being pretty much equal to the JBP Stage 2 cams? I thought they were equivalent to the Mantapart street cams but the JPB Stage 2s were quite a bit more aggressive. In fact, from the sticky here, and from JBP's website...
Secret cams:
Intake - 200* @ .050" with .360" lift
Exhaust - 200* @ .050" with .375" lift
JBP Stage 2 cams:
Intake -
260* @ .050" with .377" lift
Exhaust -
268* @ .050" with .375" lift
The Stage 1 JBP cams are about exactly the same as the secret cams (slightly higher lift on the intake cam with the JBP), but the stage 2 has a much longer duration and a good bit more lift on the intake cam.
So with the stage 2's, how do you think my idle would be?
Oh, on import performance's website, their kit only covers 92-00. I have an 01. will that work on it, or do you know another place for the package?
Is there a better oil pump than the 2.3? if not where can I get the 2.3?
Have you guys heard of any sites giving deals when you buy all of the internals, turbo, etc.? I mean if I were to buy it all at one place.
Thanks
There are others who have the JBP Stage 2 cams - so if one of them would chime in they could let you know how the idle is. I don't personally have them, definitely considering it though for when I've got the $$$. The comment about them being basically = to the secret cams has me wondering - my question is if someone actually checked them and found that their profile isn't what JBP claims it to be on their website and that they're actually about the same as the secret cams. If the numbers on their site are correct, they definitely are more aggressive.
I'm pretty sure there aren't any differences internally for the 2.4 in '01 - don't know why it's listed that way.
Don't really know about your other questions - seems that the general opinion is that the 2.3 oil pump swap is a good idea for the 2.4, then again some will say there's things you can do with the oiling system on the 2.4 that make it work just fine. And if there's a place that even sells a turbo kit of any kind for the 2.4 still, I'd love to hear of it - let alone a place selling internals AND a turbo kit all together. Don't think you're going to find that.
from my understanding the jbp stage 1 cams are equal to the secret cams, HO cams love boost
, i havent been back to the dyno but it feels like my car pulls all the way to the 6800rev limitor on the ho cams, i think the 2.3 oil pump is a must on the 2.4 build, as for boring you only want to go as big as you need to clean up the cylinders, i know some ppl where having problems with cometic headgaskets but mine is fine, i personally would stay away from copper, you have to o-ring your head or block then you have to spray a sealer to make sure all your water and oil ports seal up and its recommended to re-torque after a heat cycle, in a way the question is more of what your looking to get out of the 2.4, 300, 350, 400whp? main thing is dont go cheap do it once and do it right, oh and 2.4s are different form 95-99 from the 00-02 imo a good FI build would
eagle rods
je, wiseco, venolia pistons 9:1 comp.
2.3 oil pump, have to modify the factory oil pan (contact miller performance)
bore only enough the clean up the cylinder walls
arp studs head and mains
new bearings
properly balanced
headgasket (my choice is cometic)
head work
valves
new guides
2.4 retainers and clips
HO valve springs
cam upgrade, secret or HO, secret require no modifications, HO you have to run a HO rear cam tower and lifters, the intake HO cam has to be modified weld a cam sensor pickup and have the hex machined into it( also miller performance for modification) the 2.4 intake cam tower has to be machined for the HO lifters and for clearance on the HO cam(miller performance)
that should be a good build pretty much what im running which netted me 362whp @ 13psi
and karo and carcustoms.net should be able to supply alot of the items listed above, make sure you find a good reliable machine shop for all your work too, sorry my post has random stuff everywhere
R.I.P. Brian Klocke, you will never be forgotten
As for the head gasket I just built my engine and am using a stock replacement fel pro head gasket. From what I have heard anything more than 10psi of boost might cause it to go.

Not sure if they still do but Ross did make pistons for the LD9 as well.

The stage 2's are good the idle has a very nice lope to it. I have never ACCIDENTALLY burned tires in second gear. First time driving with the cams installed I did it though!
I have a brand new set of Venolia 9.5:1 +.040 pistons for sale

I think they did at one time. Also Diamond Racing makes pistons for the LD9, you just have to provide the specs

McFly, I'm not planning on buying everything til the beginning of Oct. If you still have them then, I will hit you up.
as far as cams, How do the JBP stage 2 cams compare to the HO cams?

That is fine. I doubt they are going anywhere anytime soon
