bought a FAST intake manifold

**bluefields88** · 02-17-2008, 06:38 PM

I got a FAST 78 mm intake manifold for my car. I was wondering if I should install it myself or just pay someone else to do the work. and how long does it take to install?

diy.........youll learn how to do it and youll feel good because you diy. someone that knows what their doing will take an hour or so. I had to do it 3 times in 1 day before and i felt like a pro lol

did you feel the difference after the swap?

**senicalj4579** · 02-17-2008, 06:58 PM

well my swap was a ls1 to ls6. But hell yeah I felt the difference. At the top end on the highway. It really pulled a little more up top

you will definately feel the difference. I also went from LS1 to LS6 like senicalj4579. Its not a very hard install just watch out for the oil pressure sending unit near the back of the manifold.

A FAST 78mm is on par with an LS6. If you paid anymore than $350 for that FAST, see what you can do about returning it.

Incorrect.
The Fast is a better performer than the LS6 on a stock motor and
everyone pays more than $350 for a new one unless it's used or bought from a friend.

The FAST 90mm almost always outperforms the LS6, with the exception of some completely stock engines. The FAST 78mm has been proven time and time again to make no more power than the LS6 unless the FAST 78mm has been heavily ported. Finally, there is absolutely nothing wrong with a used LS6 intake. Why buy a new one when used are so abundant and inexpensive? I recently sold a LS6 intake with LS6 coolant crossovers for $325 shipped.

To me its just not worth it to get any intake other than an ls6 unless you plan on putting out 500+ ponies. Then you go with a 90

**bluefields88** · 02-18-2008, 01:56 PM

I bought it on ebay new in the box for $600. I can't afford to get a new throttle body so I figured I'd just go with the 78 mm and then get a different top for it if I wanted to switch over to a 90 mm.

**senicalj4579** · 02-18-2008, 02:16 PM

your good to go man. its a good intake

**Demon_Z28** · 02-18-2008, 02:18 PM

i would love to hit up a LS6 intake w/ the EGR provisions, "have to have it in WA" would be pretty sick.

I should have one for sale in the next couple of weeks with a Shaner ported throttle body as well. Genuine LS6 intake that's been modified by SLP to use EGR.

**blackls1ta** · 02-18-2008, 04:25 PM

and i have a ported 75mm which is 78mm now with all the upgrades except polished for sale i moved up to fast 90/90,100 shipped

**bluefields88** · 02-18-2008, 09:18 PM

I have EGR, what will I have to do about it since the FAST intake is different?

**Castle** · 02-18-2008, 09:24 PM

If you are keeping it smog legal, you will need to have a hole drilled in your new FAST intake for your EGR/AIR stuff.

**Demon_Z28** · 02-18-2008, 09:26 PM

yup, thats why I want a LS6 intake w/ EGR provisions, but I dont have any spare cash for one anytime soon.

**bluefields88** · 02-18-2008, 09:33 PM

I have a drill press with all kind of different drill bits. do I just have to drill the hole?

**senicalj4579** · 02-19-2008, 06:27 AM

i was gonna just say get that code tuned out and forget drilling and all the nonsense but I see your from cali? I can imagine its a little tougher out there to just leave a plugged up egr. I hear emmissions are brutal out there.

**bluefields88** · 02-19-2008, 01:11 PM

I called Superior Automotive to see what my options are with EGR and whether or not to keep it or not. The owner told me I'd be better off just leaving it on there and that I should never take it off in California. I asked how much it would cost to have them install the intake and do some dyno runs after and he said they'd do it for $350-375. They charge $75 for 3 pulls on a dyno normally. I think I'm going to install it myself and then get it dyno'ed. save some cash.
