I'm probably going to nuke my fuel injectors but before I do, I want to buy a new Intake Manifold. I'm unsure if I should just go LT2 or go all the way to MSD.

I notice some vendors offer LT2 in stages, like Texas Speed where stage 1 only allows you to use the stock TB and stage 2 allows you to use the ZR1 95MM TB (or any TB you want to use)..

My question is, how much work needs to be done to a LT2 intake in order for it to work in my SS and run a larger TB and more importantly, is it worth it or should I just go MSD?

The big question is how much gain per dollar is either one of them?
$1500 for 7hp?

It gives other mods the air volume to peak.

Why would you nuke your fuel injectors on an intake manifold upgrade?


Induction parts, more than anything, are harmonious with the overall build combo. For example, you don't get the full benefit of a MSD without a head/cam combo that makes power out to at least 7k/rpm+. More so, you don't get much out of an intake manifold upgrade at all without a head/cam combo that flows. You can make gains just bolting on parts, but you leave untapped potential if you don't put the right parts together.

As far as untapped potential, there is bits to be had in porting out intakes and throttle bodies. The more air the car is capable of flowing, the more potential there is in a ported part. Porting won't always yield the same gains. For example, if Texas Speed claims +15whp in a ported part over non-ported, you'd have to run their exact combo mule car to see it, and the stars/dyno gods align as well. When we're talking NA combo's, there is a balance between air velocity and air volume. FI plays by somewhat different rules.

Once again, it comes down to what is your overall power goal for the car, and build combo. That is what should determine your parts list. I will say, when done right the LT2 is hands down the best bang for your buck. It's not as big of a monster as a MSD or Hi Ram, you won't see it on max effort builds. But it is the king of 500whp+ budget builds, IMO.

In my opinion, find a used ported MSD from someone and make sure it was ported by Pray, Mamo, or someone who has proven porting experience.

I did the stage 3 ported LT2. Came out cheaper than the MSD and has all the same low end power and the top end is only a few horsepower short. From all the research ive done, the LT2 is the best bang for your buck, and the MSD really only shines if you have a cam and want more top end power.

To make the LT2 fit, you just need to shave the bottom and a hose and harness extender. They sell kits for this if you want to do it yourself. To fit a larger throttle body, you just want to port the snout, but if youve never done this before its best to have a professional do it.

Looks like ported LT2 is the best bang for the buck.

You are learning well grasshoppa.

The Lt2 is absolutely the best bang for the buck. They claim 20 rwhp from just bolting it on a stock car with no tune so I tested that. I put my 2016 1ss on the Dyno and swapped the intake on the Dyno after making some pulls . Kept them engine temp and everything the same. I made exactly 20 more rwhp. The only downside to using an Lt2 intake is if you have to upgrade to an Lt4 hpfp is the Lt2 will not clear the pump. I didn't know this so I ended up buying an msd I found a deal on. If not for that my car would still have an Lt2 on it.
Just to be clear I did the comparison with both intakes stock , not ported and it was a 20 rwhp gain with no tuning. I have a Dyno jet 248 just like Pray used in the video.

That's crazy. Can you run it without making changes to the tune? Im thinking of grabbing one.

I almost want to run an lt2 intake just for the cover that goes on top.

If you run spacers the LT2 will clear the LT4 HPFP.

You can run it without a tune and pick up some power. A tune is nice to keep everything dialed in but no parameters should really change much to need a tune, it's still made for a 87mm TB and to sit on LT heads. There's enough smart in the ECM to take advantage of the better flow characteristics up top to let you rev a little further.

Aside from the Hi Ram, I think it's the best looking manifold to sit on the Gen 5 LT engines, even without the cover. I saw one that had a complete shave job done and a nice paintjob, looked really sharp. There are some clearance issues when running the cover with a stock hood, it rubs pretty good just before the heat extractor vents on the 19+ hood style. Not sure if it's the same spot on the 16-18 hoods. It gets worse if, like me, you have to run spacers to clear a LT4 HPFP. I had to actually notch the stock hood for the cover, it really did a number on my paint job. So I have to repaint the cover now that I have an Anderson CF hood. I went a couple different routes trying to minimize the cosmetics of the material I had to notch out but I wasn't happy with it. Felt like if I was gonna have the hood cut up like that, I might as well run a Hi Ram and make it worth all the cutting LOL. But I really like the Anderson hood and really didn't want to shift my setup to make use of a Hi Ram, so it worked out nice. I had a lot of visions of paint schemes I wanted to do with the cover, but this one was less wild and I could keep everything matching. Eventually I want to get custom plates made to replace the "Corvette" with "Procharged" but inspiration hasn't come to me for it, yet.
