Anyone know what intake this is? It has a 90mm Holley TB (cable operated).

And will this intake fit on a 5.7 LS1?

 

looks like a LS2 intake to me......a LS6 intake would be better ....or upgrade to a fast 92

 

I concur- 4 bolt TB on a car-style Gen IV cathedral intake. Only one of its kind.

 

LS2 Intake, as mentioned above. Could have google'd the part number on it and gotten the same info.

 

I don't have the part number unless it is in the photos. Not sure where to look tbh... I don't have the intake. It is for sale.

 

Thanks, if you could find me either, in the UK or ships sensibly to the UK, then I'd be interested.

Suspect a FAST 92 is beyond budget no matter really.

 

Dorman LS2 or Fast intake would be better than a factory LS2 intake.

 

This pic here, this is on the drivers side.
It says:

FIRING ORDER
18726543

Literally above the word FIRING ORDER is the GM Part Number. Fuel Rail is in the way in the pic.

As people mentioned the LS6 or Dorman LS2 is much better than this one. Yea if it's cheap it'll get your setup together, but there's much better out there.

 

Any pointers on places to get either? Can't see the Dorman one anywhere for sale.

 

Thanks, but as said, I don't have the intake, it is the 'only' used intake for sale on ebay.co.uk and the seller has it listed as an Ls7 intake.

Yeah I know, but finding anything this side of the Atlantic Ocean is a challenge. I had an LS6 intake on my previous Camaro, wish I'd taken it off before selling it, but didn't for some reason. So currently I'm stuck with the original LS1 intake. Just exploring options.

 

The Ebay seller is full of it. That is a cathedral head manifold. LS7s had their own rectangular port head.

 

Pretty sure Summit sells it but it might be out of stock. Not sure if they would ship to England.

 

OP,

You've gotten great advice here. It’s an LS2 intake, as others have said. While it’s not the most sought-after option, it could work if you need a replacement or don’t have an intake.

Here's what we would like to ask. Do you need a manifold for a specific reason, or are you just looking to upgrade your LS1 intake? Sometimes, sticking with what you have is the better option depending on your needs and budget.

As a heads up. The Dorman LS2 intake (615-901) has been discontinued by Dorman with no replacement. We confirmed this with Dorman. The FAST 92mm (FST-54039B) is a solid option.

We ship to the UK and can provide a shipping estimate on our site without any commitment to buy. Let us know if we can help!

 

Many thanks for the link. I have bought from you in the past and ironically have been compiling a Wish list for when I get my bonus in March.

Would you be able to point me at the correct TB to go with this? Would I need anything else to install on my 1999 Camaro? Being in England I need to know I've got everything before doing any work on the vehicle, as it won't be quick to source any additional parts. Thanks.

 

Throttle Body depends on what Intake you use.

 

what other mods do you have that are requiring a new intake?

if youre still on stock cam/heads the gains on an LS6 or aftermarket intake are going to be pretty minimal

 

OP,

Thank you for your previous business, and the wishlist sounds great!

We agree with @1988montecarloss that swapping intakes without pairing it with upgrades like heads or a cam doesn’t yield significant gains. That’s why we asked about your reasoning behind considering an intake in post 13. If this is part of a phased approach to building your setup, we understand. Our goal is to help you get exactly what you need, while ensuring the effort and cost are truly worthwhile.

As for the FAST 92mm intake, we’d recommend starting by reviewing the installation instructions, which you can find here by entering the 54039B part number. It’s a solid upgrade that shines when paired with complementary mods. If you’re also considering a throttle body upgrade, here’s a basic parts list to get you started. It’s a great foundation and can be expanded based on your specific goals.

1. Intake Manifold: FST-54039B
2. Intake Port Seals: FST-54009-8
3. Throttle Body: FST-54091
4. Coolant crossover with rear plugs: SUM-220963
5. Fuel Injector O-rings to manifold: FEL-ES70599 (need quantity 2)

Let us know if we can be of any further assistance.

 

Thanks for the direct links, Makes it so much easier to add when viewing your site.

To answer the questions on setup.

Road driving is somewhat different here in the UK compared to the USA. Our roads are generally a lot smaller, more twisty and often poor surfaces.

Drag racing on the street just isn't a thing here, not even from a roll really. But driving and going up and down the gearbox with a broad speed range is much more the thing. Probably similar to canyon carving, but generally much smaller roads and tighter bends with less visibility.

The Camaro is great and surprises a lot of people, as most Brits just think "Yank tank" and expect it to be slow and wallowy in the corners. It is anything but.

Mods at the moment are limited to SLP lid, K&N filter and SLP Loudmouth catback. With CTS-V 4 pot front brakes and zo6 discs (rotors), slick shifter and some Strano suspension parts.

However, it is too tall geared, meaning you are sometimes too low in the rev range and don't get to change gear enough, from a fun factor point of view. On slow corners you are down to 1st gear way too often. And it can feel a little breathless at the red line. Goals are to shorten the gearing, make 2nd more usable on slow corners and make the engine feel more exciting at high rpm.

I should be getting a bonus in March and I plan to order (my Wish List at Summit) some 4.10 gears and some more chassis upgrades. But I'd also like to improve how the engine feels at the top end/red line. On my previous Camaro (also a '99 z28 but an auto) I did swap on an LS6 intake and it made a real difference to how the engine felt at high rpm. I'd like to improve my current z28 in this regard too.

Being 100% honest, if I could find an LS6 intake for sensible money, I'd go down that route, as it would likely be more than enough for my needs. But they seem like unobtanium. Which is really only leaving the FAST as an option, unless anyone has a better suggestion.

In March I will also be getting some long tube headers btw.

I do plan for at least a cam or cam & heads down the line. Although ultimate HP isn't the goal, more how the vehicle drives and feels is. I guess the closest analogy would be to make it more of a tarmac rally car inspiration, ripping through the gears. Enjoyment and how the car feels is far more important than outright pace or rwhp. As there are no trophies to be won and no prize money at stake.

Here is the car on a typical sort of road it gets driven on, as you can see it is quite narrow and a relatively poor surface.

 

Before I bought a bunch of engine parts I would swap the 4:10 gears mentioned above and see how you like it. You can add the engine mods later as needed and money allows.

 

x2

the gearing will make the biggest seat of the pants difference and i cant imagine would cost too much more to get over there than we pay for them here
