I'm in the process of an N/A build. I need some help from those of you that would KNOW! Which intake manifold should i use in order to get the best performance? 2.3 LO, 2.3 HO, Venom, or is there another choice? Also i want to go with the biggest T.B i can use, i can find a 62mm so far. Are there any that are bigger than that, that i can put on my car?

Incase you wanna know what kinda car.. its a 2000 cav. 2.4

I noticed a pretty good gain with the HO intake...although thats only my butt dyno I dont know what the real gains are. But past 3500 it pulls harder and when I stomp on it from a stop I spin the tires a little, never did that with the stocker.

my 2.4 stays spinning for days with out the HO mani.. with kumho tires .

yeah the HO intake works very well. nice gain i'd be careful how big you go w/ the tb. i think 62 mm is plenty big enough


People say that what doesn't kill you in this life
will make you stronger. I'm not sure if that is true
or not, but i do know one thing-You have to learn from
it and it has to make you better.......it has to.......

With my old tires Eagle RSAs it would spin all day but I got some Continental ContiExtremeContacts and it wouldnt anymore.

does anybody know anything about the venom drag manifold?? besides it being VERY expensive, does it work better than the HO off the 2.3?? im having the car built (complete bottom end) and it will be tuned. so im needing to know which way to go on this Manifold and T.B. Issue.. i want atleast high 12's with this.

From what I have heard it is a waste of money.

mine has always done that 2.3 FTW !

The HO manifold was designed to compliment the higher revving Quad 4 (short runners and larger plenum). The Venom manifold for the 2.4L is basically a stock manifold made of aluminum with a slightly larger plenum. I would strongly recommend not wasting your money on the Venom intake manifold, Venom fuel rail, Venom 400 chip or venom xxxxx (for J-bodies at least).

"Youth in Asia"...I don't see anything wrong with that.

I would definately agree about the venom manifold, don't get it. Also, as far as the HO manifold goes, i didn't gain a single thing in the 1/4. that is also having a dremel job done though, and using the same t.b. on both manifolds. i have the adapter flange, so we'll see if that makes a difference. I figure it this way, even though it didn't gain me anything in the 1/4, it also didn't make me lose anything, so why not put it on cuz i think it looks a heck of a lot better. just my thoughts.

Stick with stock.



FU Tuning

okay.. im between H.O and L.O now, is there much of a difference in these 2?

When I step on the gas, I want people to think the world is coming to an end! - Homer J. Simpson

the HO mani was designed to support the higher reving HO ..the LO reved to the same as your 2.4 ..so are you going to be revving any higher? ..to answer your question i dont think the HO will hurt you any but the LO will support a NA 2.4 build just fine.

we can guess all day long here. I did not see a gain or loss in HO. some will say it hurts you, some will say it will give you gains. Their really is no way to know unless someone actually dyno's it. I know someone will come on here saying didn't someone dyno it to prove 10 horsepower gain, but loss in tq. NO they didn't, they never once provided any dyno sheets, so until someone does, it is not proven to do a thing. A lot of people will say don't get it unless your going turbo, but again, no proof. so unless you want to be the one to dyno the difference between all 3 manifolds, or unless someone else does it, their is no proof of anything. people are just telling you what they want to believe. They are taking the best educated guess they can by saying the 2.3 was higher reving, or because the way it is made it would be good for a forced induction setup, but not N/A. They very well could be right, but again, someone needs to dyno it. I would say the best person to do it would be someone who is either stock or close to stock who is going to dyno their car anyways. then they just need to setup their car so that way they can swap out the manifolds as quickly and as easy as possible, and then have them dyno it. It would be harder for someone who has a turbo obviously because of charge pipes and all that fun stuff. Until then, just go with what you want.

actually i plan on rev'n a little higher, but only about 700 rpm's more till shift point.. so will that make a huge difference for me or not? im going to try to build a high 13 second N/A. but then i'll be adding nitrous later.. so im trying to find out from those experienced which will be better in the long run.

I think for your goals you need to consider better things than an intake manifold and throttle body. Also with the automatic what are you using adjust your shift points?


~Boost. Its what's for dinner!~

I need one that looks great for show? Any Intake Manifold and TB that is Polished or Chrome?

it just depends. for the 2.4 guys, i think the HO manifold looks great when it is cleaned up and done up, but that is what i like. you should really just search around for w/e is out there, and take a look at what they look like, and see if it is what you want for show.

As for better things, how do you know every other part of the car hasn't already been decided. you haven't asked him any questions, so to say something better is kind of crazy. everything has to work together, so the intake side is important, just as exhaust side is important. what if he goes to big on the t.b. or too small. what happens if his exhaust is to small, or to big. yeah that stuff doesn't seem important until you think about how the wrong size of exhaust or wrong size t.b. can really hurt you.

okay.. if i have to list everything it's going to take a long time.. but i'll try.. eagle rods, weisco pistons 10.5:1 bored .020 over, 1mm oversized valves, knife and balance crank, deck head + port and polish, deck block with .020 over bore, arp main bolts, arp rod bolts, seceret cams, 79 gram wrist pins, clevite 77 main and rod barrings, 320 cc injectors, msd ignition, lsd insert, port oil feeds, pacesetter 4-1 header, 2.5 inch exhaust, high flow cat (no resonator), CAI, and im wanting to go with a 62mm T.B. but this is what im trying to find out.. the better combo for best reliable performance. How does a 2.3 LO manifold and a 62mm T.B work out? Well i hope cause im about to purchase a L.O. (and yes i know - i'll get the chris fontana flange) after i get all of my mechanical and machine work complete, it's going to be HP tuned. so like i said.. from those of you who KNOW, help me out here!!

oh, don't let me forget the unorthodox pulley that's on the way also.

arp head bolts- not rod bolts.. geez .. anyways.. you guys that know from experience.. throw me some ideas and hints here.

check my registry




SPD RCR Z - '02 Z24 420whp
SLO GOAT - '04 GTO 305whp
W41 BOI - '78 Buick Opel Isuzu W41 Swap

speed, you don't know how many times i've looked at your registry...LOL.. and also Karo's (even though he doesn't list parts).. where did u find a 65mm T.B for our cars?? the only difference in what your registry says and what im about to do(engine wise) is the compression of the pistons.. and i thought more about a 62mm T.B.. but if i can get a 65. hey. im there! haha

how much of a difference is there in the L.O manifold and the H.O. manifold??
