Best Intake Systems?

**Ghawk996** · 09-12-2008, 06:13 PM

Hey I am looking into upgrading external engine parts and was just wondering what the best parts would be for them money all around. I don't plan on going into the internal features of the engine till it goes out so I just want to know how far I can push the LS1.
So that brings me to the question of what would be the best intake for the money? I have been looking at performance products Typhoon #52065 which is a LS2 intake that excepts LS1 injectors, or should I be looking at an LS6.
What type lb. injectors could I use with these set ups and such?

ok well several things...fack the ls2 intake manifold..go for ls6...unless your going head and cam..which i assume you will do if you want to push the ls1 to the limit..in which case you will want to run the fast 9x/9x..fast excepts your stock fuel rails and injectors. ...injectors do not need to be changed until you go cam..or cam/heads.

Does anyone know what the inlet is on a LS6 manifold like say 92mm and which ones off of other cars will fit mine? I don't want to purchase anything that I won't use later when I get into the motor after college!

it is stock ls1 size..i think it is either 72,76,or 78 ..sorry for the confusion..but the ls6 is a bolt on..the fast9x ...you need either an adapter for the TB.or pick up a 90 or 92 tb

If you are not going to extreme an ls6 intake will be just fine. Going a little more extreme? Fast 90 or 92. I might suggest a ptm throttle body. Cheap and really, really nice!!!

What ever you do stay FAR FAR away from that P.O.S. Typhoon.

Is the typoon really that bad of an intake system, I really haven't looked into them that much.

Yes, Fitment absolutely sucks. Its a metal manifold so it gets heat soaked and performance goes way down. Do some research on here and tech and you will see that not 1 person will recomend it. for the same price get a LS6.

Just get it over with and Buy a FAST 92 and a PTM 92 TB.

PTM TB's are very nice.

So I have an 1998 model LS1 which LS6 intakes can I use say from make and model of other cars. I just have noticed that some have a different style mounting for the thottle body.

Get a ls6 intake from a 01 or 02 F-body, as they were stock on the ls1's for these years.

**shady milkman** · 09-14-2008, 05:15 AM

any ls6 intake will work..but ones off of vettes ect require some modification..

**Ghawk996** · 09-14-2008, 05:29 AM

So will accept the LS1 style injectors or will I have to purchase them with the LS6 intake?

**shady milkman** · 09-14-2008, 05:34 AM

it accepts the ls1 injectors and fuel rail

**Ghawk996** · 09-14-2008, 08:33 PM

I guess I have to pick one of the two! I am thinking about just going ahead and getting the LS6 since I have a stock motor. Does anyone know what hp gains I will get with this one? I see that the Fast 92 advertises 15+ hp gains!

i believe its 15+ over other aftermarket manifolds..i would say you will see 15+ with a ls6 swap..i am waiting to do this mod myself

i am told you can feel it..which is always good.

I installed my 92/92 on my WS6. The heads were already ported and had Kooks 1 7/8's LT with custom exhaust.

You can feel it... just dont get really really worked up over it. You might be disappointed. I definitely felt a major increase in throttle response. Also the upper RPM's it was noticeable. Mind you, this was going from a stock LS1 intake and a stock LS1 TB. Its not gonna be a "oh shit, pin you in the seat increase". But you wiil feel difference.

Also, I gained 2 MPG with my TB!! Mine was drilled though causing erratic idle.

ebay ls6 intake is about 300 if you dont find one in the parts for sale section

**Ghawk996** · 09-15-2008, 09:22 PM

I am going to start looking around and see what I can come up with. Also how large of TB can I put on the LS6?

i'd stick with the stock tb for now.

stock can handle ups of 500 to the crank

honestly, having been there and done that, forget the Ls6 intake and get a FAST 90/90 and port the sum-a-bitch and call it a day...

i went from an Ls6 intake/stock TB (non P&P) for a FAST 90/90 Tony Mamo ported (additional porting by me), and picked up 35rwhp/10rwtq over the Ls6 set-up. sure, not everyone might see this, but again, that's OVER the highly praised Ls6 intake...

injectors only need to be swapped out once duty cycle nears 90-95%, IMO. i was putting down 443/402 with stock injectors. recently upgraded with install of U/D pulley and Meziere EWP...
