Question my friend is going LS Turbo which Intake Manifold do you guys suggest?

 

LS was not meant to rev, i think the best choice would be skunk2.

 

I like the Victor X manifold. It has good top end gains with turbo setups. I want to see what kind of numbers this manifold would put out

 

Incorrect, with a Z10 block girdle and a balanced bottom end the motor will rev just as relieable as any Vtec motor. I would suggest a sheetmetal intake manifold.. that gets my vote...
Also - ARP head studs and rod bolts are suggested for those higher revs...

Just cause its safe to rev it up to all heavens doesn't mean it will make power up there...

 

That victorX manifold is the most disgusting manifold I've ever seen.

A turbo likes a huge plenum. Usally about 1.5 times the size of the motors displacement. It also likes shortish runners that aren't too big in dia. Plenums with walls that at face eachother, like the VictorX, are bad because a resonance is created between the walls. An irregular shape is good for elimating the possibility that the reverberation created by the motor's revving would disturb air flow.

A type R manifold would be pretty damn good. Doesn't some company make a copy that has the correct bolt pattern for the LS? I can't remember who right now.

 

The skunk2 is the best/cheapest mani you'll find for the LS. The skunk mani's are basically replica's of the "R" manifold with the correct bolt patterns for LS engines. The JG/Edelbrock Victor X is just overkill for an LS engine. You wouldn't see gain's over a skunk2 unless you were revving to like 8000+. Find some LS cams that'll make HP that high and more power too ya. The high lift/low duration cams for LS seem to extend the torque/HP a good bit. Stock LS cams take a nasty dive at anything above 6000 or so.

I've got a skunk2 on my setup and think it's the shizzle y0!

Skunk

 

where is the love for venom's manifold?

 

Is an LS supercharged reliable? and will it make at least 200whp.. I was rounding up turbo parts, but just too much of a hassle to get all the parts piece by piece. I'm gonna save up for a full jackson racing supercharger kit, cuz i want instant boost and I care about my engine. I know turbo guys blow **** up, (not all the time with proper maintenence) and i just want at least 200whp..

don't flame please, I love Turbo to death, but just can't afford to lose my a/c or live paycheck to paycheck.. lol

 

yes a LS engine with a Si or type-r supercharger kit will work just fine. you will have to modify the intake manifold which we can do for you. With the larger blower it will make 200@the wheels @9psi or so. Teamklr.com. We have a ls motor in a 92 hatch the motor had over 200,000 miles on it and it ran an 8.80 on street tires in the 1/8th mile. Pretty sweet huh

 

 

its good for drag cars, but on the street its a bit too much...in most instances

 

what would be a good TB to match up to the Skunk2 mani and still maintain my cruise control?

 

AC Autotechnic makes power on all my customers cars including LS's just get good valve springs. LS motors definatly need them on boosted applications.

 

stick to stock for now.
