Having a built 416 with L92 heads and an LS3 intake manifold. Its going in a C5 vette that is DBW. What throttle body options do I have?

Am I limited to these two?
Stock 90mm
NW 102mm

Also will the NW 102mm fit a factory LS3 intake manifold? Thanks!

(I plan on getting the fast down the road.)

 

I am running a 92mm NW on my LS3 in my 00 Z28, works great. I put down 465 on the dyno with a bone stock LS3

 

ERL makes a 102mm also, but its plug and play for C6
NW is plug an play for the C5s.

Im running The 90mm OEM throttle body on my FAST right now.

 

Has anyone tried the edelbrock one? It looks cheaper than the others and comes with sensors. I've never had quality issues with anything made by edelbrock.

We need a cable operated 90mm TB for use on an LS3 intake. Was going to try this one.

 

My main question is if there will be any interference running a 102mm Throttle body on a factory LS3 intake manifold. I do not own a throttle body for an ls3 manifold and I don't want to drop another thousand bucks on my build buying a fast as I already own a factory LS3 manifold. Looks like a 90mm will cost me about 300 and the nw 102 will run me 500. So I'd rather just buy the 102 for 500 if it will fit a factory LS3 manifold. Any other companies building drive by wire 102mm throttle bodies?

 

Sub'ed!

Well I just purchased a NW102 MM TB. I'll be bolting it up to the stock LS3 intake manifold as soon as it arrives to see if you need a spacing kit to allow the big bore throttle body on a factory intake.

 

When I had the NW120mmDBW TB it boltd up to my factory LS3 manifold..Although th biggest you can really open the mouth of the manifold to is 96mm...Anyways it does fit..

 

if anyone finds anything and wants to offload their stock stock LS3 TB and/or intake (incl. injectors, rails, bolts), i'm in the market. PM me.

 

i just bought my LS3 intake, stock fuel fails, and stock injectors off of a LS3 corvette from ebay for 305 shipped to my door. the company i bought it from is a corvette recycling yard and they said they had like 8 set ups left.

 

NW has a new style plug and play 102mm TB

 

I run a NW 107mm on a modified FAST LSX so I know he makes them at least that big
