I'm trying to get an intake manifold by May. i have a timeframe because I have been telling everybody it is coming in out in May. the BBk one is only 620 from Summit with throttle body included, but they have not even shipped. At fiest they said they will be shopped by April 1 nwo they are saying April 15. Reading in forums here I'm convinced that BBk takes like four years to ship their stuff. So from that, Summit now has the FAST manifold for $790 no throttle. I'll get it later. Which one shoul I get?

the FAST, you can check the intake flow test i posted in the internal forum.

Get the 90MM fast intake and then get the TPIS 90mm Throttle body to go with it later on. I dont know though if you would be able to run the 90MM LSX intake with you stock throttle body. I know theres an adaptor for the 78MM LSX intake but I dont think there is one for the 90MM.

What is the difference between the 78mm and the 90mm? I mean besides the size difference? don't they both give the 20 HP boost?

the 78mm is on par with the ls6, not worth the swap for the money. its been proven time and time again. get the 90 or nothing.

I know you heard this a lot but your help is priceless, appreciate it man. back to this manifold query, the 90 mm kit is like $1300!! that is alot I'm going to have to wait more then. What is the TPS thing they offer with those?

Throttle Position Sensor...you can buy the throttlebody with a new TPS installed, or you can just swap your stock TPS over to the new throttlebody...

please clarify? do i need it?

I would not purchase a new one if it were me...I would buy the throttlebody without the TPS option and just unbolt your stock Throttle Position Sensor from your stock throttlebody and bolt it onto the new throttlebody. It is the round plastic sensor on the driver's side middle of the throttlebody...it connects to the main shaft that goes through the middle of the throttle blade...FAST offers their TBs with a new sensor installed...for convenience, I guess...hope this helps.

Here's a pic from LS1howto.com it's the bottom sensor of the two shown:

thanks but definetely the seals they offer or use the stock ones?

LawmanSS

iTrader: (19)

If you mean the intake port seals, then yes, I would definitely replace the port seals when installing a new intake, the stockers can be reused, but I don't recommend it...the TB should already come with a new seal, if not, I would buy a new one also...

what are your current mods and the end goals and application? that should determine if ~1300 is worth it to you. on a h/c setup the 90/90 is worth ~20rwhp. if you want to maximize a bolt on, cam only, or h/c setup then you'll want the 90/90. if not the ls6 and ported stock TB will better suit your purpose and wallet.

and thanks

My current mods are as listed;

1. Mti clear lid
2. K&N filter
3. free ram air
4. slp bellows
5. Granatelli cold air MAF
   
   My end goal is an 11 second car or just 600 hp nothing monstrous. $1300 is a lot but it is just with my paycheck it will take a month or two to save up. Like it says on your exhaust/induction guide, my 01 trans am already has a LS6 manifold. I do want a head and cam package but that will be done by September if I really want to after the rear end too. mY daughter wanted the rainbow on there

my kind of chick, "600hp, nothing monstrous". for the HP goal you will need the fast intake, for your E.T asperations its not a neccessity. 1300 is alot but you also have to realize that once you start putting down serious horse power adding more w/o the aid of more displacement or n2o becomes increasingly hard. so in hindsight 1300 bucks for ~20 is a pretty good deal.

You do realize how much 600hp really is right? Thats gonna take a lot of cash and a lot of mods.

Yah I know that is is a lot of cash but it is just that the bbk manifold with throttle is only 700 and just the LSX manifold by itself is $900!!!

Save your money on the LSX and just get an ATI Procharger or one of the new turbo kits out. If you spend $1300 LSX, $1000 on a cam, rockers, pushrods, springs + installation, and then $1500-$2000 on a good set of heads, plus dyno-tuning for around $400 your still going to be around 420-450 RWHP and your gonna lose gas mileage and drivability. With the ATI or a turbo kit on a stock engine you will be making between 450-500 RWHP which translates to about 520-560 Flywheep HP on a stock engine with the proper fuel and oil management upgrades. Then if you decide to get headers and exhaust and a blower cam you will be well over 500 RWHP and the car will still drive like a daily driver. The ATI kit with the fuel pump, fuel injectors, blower, and dual intercoolers is about $5500, which in the end is probably a better deal unless you want the sweet sound of a large cam over the whine of a supercharger. Good luck though with whatever you choose!

i dunno much about the BBK intake yet, but i would guess that it suffers the same heat soak problems the weiand intake does. The LSX 90mm intake is considered by most to be the BEST intake out there for us. just don't get the FAST 90mm TB. the TPIS seems to be the preferred alternative. high 11s is possible with complete bolt ons and a healthy shot of nitrous. 600hp is a lofty goal, especially for a DD. Phamspeed has some turbo kits out there that would be a good start. read up alot in the forced induction section.
