I believe they also do just the throttle body. Price for other engines is around $180. Then port your manifold yourself to match. That's what I'm gonna do 8) (when I get my fuckin emanage working lol!)

PS: Vlandis, how was the quality of the job done on the throttle body?
haha fair enough.

you need to get the emanage working i think its going to help you lots out on the track!
its a waste not being used man.

yeah excellent job. all very smooth and done well. no imperfections.

who ever gets the next one might get my old TB haha

If you are going to all that hassle you are as well getting a fabricator to split the plenum and make a new upper for it where you can either fit a bigger TB from another car or, as has been done in the UK ;) , fit twin FTO TBs

So long as you have the software to make the car run on the increased air it will be drawing in of course!

Just thought I would clear up some confusion on the throttle bodies.

The stock throttle bodies on all FTO V6 engines are 60mm internal ID (Butterfly).

The stock manifold with very light porting work can handle the stock unit bored out to a 63mm butterfly with no problems at all.

The 65mm upgrade is using a different throttle body and requires the manifold to be welded and then reported as the shape is slightly different and we need to do more extensive porting work. We used to be able to do a 70mm throttle body but our supplier turned out to be a time waster on the billet units and we dropped the range.

Being naturally aspirated throttle bodies make impressive gains especially mated up with other modifications.

Interesting, I was going to email you to see if the 65mm throttle body was available without manifold, but from what you've said above probably need to get both together.

Do you do the 63mm upgrade for the FTO, throttle body only?

Also I did read on another forum about a 6 pack throttle body for the FTO? Does this exist? How much? :D

Where are you measuring it from? All butterfly diameters on all FTO models are only 60mm. The throttle body is actually slightly tapered as well so its larger and then tapers into the middle back to 60mm. Unless the unit you have has already recevived a bored out unit
