Actually, you are.

The good news is the ported LS2 manifolds are showing very similar gains to the ported Fast90 manifolds for about $400 less.

I find this hard to believe since stock they make less power than an LS6 intake.

It was worth it to me, but everyone's different.... some say yes, some say no. It's really about matching all the parts to work well TOGETHER.

With the old set up(LS6 intake/stock ported TB), the car made 435/405 on two year old TEA S1.5 5.3's, and a lil' old F11 cam(228/230, 585/595 112+3*)through an M6/12 bolt/4.56's/28" slicks/supporting bolt on's with FULL exhaust and FULL belt.

After the the swap, it went 457.3/423.9 on a safe(a tad fat)N2o tune w/nothing else changed. That's a gain of 22.3 rwhp/18.9 rwtq.

On a side note.... the HP peaked at 6200(I've advanced the cam a hair)and held level all the way to 6900. The TQ. went from 340 @ 2600, to 400 @ 3900, and peaked at 423.9 @ 4600 before falling slowly to 350 @ 6900.

Your results "may" vary-

Sorry dude, I did'nt get it. LOL.
Is there any proof of your claim to the ls2 intake? I would like to see it.

Also, I love your sig. LMAO.

I like hearing this. My tea 5.3's are an older set. But I have a 232/240 595/608 on a 114 lsa cam. So thats a bit bigger than what you had cam wise.

Now when you say a fat tune, do you mean rich in fuel???
And also did you have the fast port matched to the 5.3's???

I would be stoked to hit 460 or so. But I know there is no garentee.

I also know the set up will cost 1150, but I will be able to sell the ls6 int and bo-white ported tb for about 500 bucks so that will be like a core charge. Leaving me only paying 650 for the swap.

Fat = rich.
If that's all you'll have in the swap, I'd say do it.
Don't see why you wouldn't hit 450+ if everything else is "right".

Good luck-

Depending of the condition (and stage) of those TEA heads with that cam you may hit 450rwhp with out a FAST. That is more cam than I have....

Oh yee of little faith. When I was running stock exhaust manifolds and cats, ported TB and LS6 intake with a little 215/230 cam, I swapped to a Mamo ported FAST 90/90 and picked up the following rwhp. Look at the torque gains. Don't you think that's going to be worth more than a tenth? Of course, now I'm running headers and a much bigger cam, but look at the power and torque. Not bad for running little heads.

27 hp 20 ft lbs of tq. for $1150.00 thats still kinda hard to swallow, and your results, from what I've seen, is not the norm.

He said he'd have roughly $650.00 in it after the sale of his other intake/TB.
If see's 20/10 that's a good cost to gain ratio IMO.

I have a ls1 intake and a ported TB. Instead of going the ls6 route for 400. I figure spend 1200 and get a larger gain and i can still sell the TB for a few bucks. If you want 450 you will probably need it anyway. I have a moderate cam that leads me to believe the 90/90 is more of a gain.

Ok Jeremy, heres the deal. You buy this. If you gain more than 25 RWHP and 20 RWTQ with NO OTHER CHANGES, I will make a thread in CICC admitting I was wrong. If you don't get those numbers, you have to proclaim my car as being the sickest PIMP ride in central Indiana... in your sig... on every message board you visit, and you must include your sig in every thread/post you make.

Well as you know, once you get to the hp level you're at, the additional gains become harder and more expensive to achieve. My results are not typical because I had my intake ported by an expert. I gained more than average, but without the driveability downsides usually associated with these type of gains. It's all about more airflow. Bolting up the ported FAST was like bolting up a set of heads that flowed 20 more CFM.

Further "Combo" with attention to detail. The detail really comes in when matching your components and sorting out internet myths. Patrick's is a shining example.

I'd use the Fast intake, but not the throttle body. Too many issues with their throttle bodies.

I plan on going fast/NW if I do buy it.
Is it worth using the tea 5.3's or sell them for some milled ls6's.

Hell no, thats to big of a promise to make. I might not get 25. But I think I might get 20 if I port match it. And get the tune dead on.
