Intake Manifold

My stock intake manifold is leaking from the rear, so instead of just fixing the leak im going to look into getting an aftermarket manifold since the old one will be off the car anyway to fix the leak. My friend Tim suggested either the Edlebroke manifold or the Accel SuperRam. In addition to the manifold base I also want to invest in some runners. Now i know Jegs has the accel SuperRam Kit thing which comes with the manifold base, runners and Plenum with bolts and gaskets for about $780. I guess my question is... Could i mix the Edlebroke manifold with the accel runners? Or would i just be better off sticking with SuperRam all the way?

I could be wrong, but for 780, I think you get just the SR runners and plenum, then you need to still buy the base.

The bases should be interchangable, between the Edelbrock and Accel...since both say they accept stock runners.

If it were me, and I had it to do all over again, I'd go with the full SR setup...I currently have the Accel base and runners and stock plenum, oh well, try to save a few bucks...

I'll have to call up Jegs and find out for sure what comes in the SuperRam Kit. From what i saw in the picture it showed everything which now that i think of it, it would be a little too cheap for the base, runners, and plenum for only 780 bucks. If anything, for now I'll just get the base and runners and look into getting the plenum later.

The runners in the SR kit can only be used with the SR plenum. Just in case you weren't aware of that. The base can be used with any runners and plenum.

You might want to do a search. That SuperRam is awesome, but it can also be a pain in the neck. IIRC (and I'm sure someone will correct me if I don't) there is interference with the windshield wiper motor. That is probably the least of the problems.

Wow, I knew this stuff was expensive, but didn't know it was THAT expensive. The way I'm going is A LOT cheaper. If you don't care about your EGR working, then go buy the intake manifold and fuel rails off of a '94+ LT1 motor and have John Millican modify it for $200. By the time I get my swap done and running, its going to cost me $46 for the manifold, $50 for the fuel rails, $220 to get the intake modified, $65 for a remote t-stat housing, and however much it costs me to make the fuel line hoses. Comes out to $380 plus fuel line fittings, with shipping included in those prices.

LOL Duron, you must not be aware of the emissions standards in New Jersey. Without my EGR I'd never pass my state inspection in 2006. That is a good way to go though. So what I might do then based on the feedback Im getting is get the Edlebroke manifold and then get the SR runners so that later on down the line i can get the SR plenum. Or maybe the otherway around, Im getting a little confused here. Get the SR base and maybe the SR runners. Ill have to give it some more thought.

For the kind of money you are spending you could by the stealthram setup.

For the time being Im just going to stick with the super ram base and then after i get more money I'll go for the SR runnners and plenum as long as the runners have EGR ports.

Stealth Ram has no egr either.

My advice would be go with the full Super Ram now...why spend money for the runners, when you'll upgrade later? Sure, you can later sell the runners, but not at a price anywhere near you paid for them.

Ask me...I know

I never planned on going with the stealth ram set up. I was going to get the Super Ram base and then later on down the line get the runnners and plenum. lol why aren't you happy with the base -runner combo you have now?

It's not that I'm not happy, it just doesn't have the potential that the SuperRam does.

re: my reply regarding the HSR, was meant for the person who suggested it to you.

Let me explain a little more.

I went with the Accel base/runner combo at the time, because I figured it would be the "last upgrade" I'd ever do to the intake, or the car for that matter, beings as it was my daily driver.

Since then, and three kids later, the IROC sits doing nothing, more often than not.

So, since the use of the car has dramatically changed...i/e I can't squeeze the whole family in it an go anywhere, I wish I'd have just gotten the intake that could support the HP that I want now...with a LTR TPI, you're kind of limited with cam/heads approach...I/e if I had the Super Ram already, then I could hit low 12's for just a cam and head swap...sure, I could still go 12's with my intake, but a mild cam (like LPE219), SuperRam and 180/190cc intake runner heads would push low to mid-12's, where as I'd probably be low13's, maybe high12's with the same cam/head combo and my intake.

Like some of the other people on this post I am speaking from experience. I have an Edelbrock base with Accel SuperRam runners and plenum. If you can't afford to do the whole thing now just get the base and you can always swap runners and plenum later. Believe it or not simply changing the base can yeild a decent power increase. Just compare a stock base to any aftermarket unit and you'll see what I mean. As far as the SuperRam being a PITA to install....well yes and no. The wiper motor is easily fixed by removing the mounting grommets, that will yield enough clearance. The only other hard part is bolting the plenum to the runners...I modified mine to make life easier but it can be done, t just takes ALOT and I mean ALOT of patience. The choice is yours but if you can afford it get the entire SuperRam, if not get a good base (Accel, Edelbrock, TPIS) and you can always add the SuperRam runners and plenum later.

Seeing as I live 1500 miles away, I guess I wouldn't know the emissions laws in New Jersey. You can always get around them though Here, I don't have to pass a visual unless I fail 3 times, and EGR only reduces NOx, which they don't test for here

Follow the other guys' advice.

Yeah! I would buy the accel manifold from ebay 397.99$ and stick with the stock runners for now, and then upgrade to the upper superram runner/plenum combo... I had a ported EDELBROCK manifold with SLP runners and I recently bought a superram combo... A friend was running 12.26@112mph with the superram and I was going at 13.10! As you can see this intake is a step higher and a stock plenum is just no match...

Good luck with your project,Pat

By the way I still have my polished SLP runners for sale...

I was lucky in my state's emessions test. They run your VIN into a computer and add in wear and tear to the engine to see where your vechiles emissions SHOULD be at. Little did they know, that the VIN number they ran was for a carbed 305 not the TPI 350 in there now. My emissions were way below what they should have been.

What other types of problems might I face in installing the Accel SR compared to the Edelbrock? As it stands, it will be my first time doing this and i might have to enlist the help of my friend Tim, if he would be able to, to gave me a hand. Basically Im a new do-it-yourselfer as far as cars go, like i know about the parts but the install is a different thing. What are my chances of doing this without screwing something up?
