Custom ported and CNC throttle bodies, upper and lower manifolds by Synergy Composite

Sh0velMan

Needs to be like for like compared against the Z1 manifold if you want any results you collect to be meaningful.

Z1, whether you choose to believe them or not, has provided such results with their marketing information. You would need to do the same if you want to present the product as superior. Otherwise you're going down the Akuma Motorsports Intake vs Stillen road.

Also, you, or the guy actually going to be making and selling these things, will need to get a vendor account on this site or the site operator will be highly displeased with you.

Good luck! Definitely watching and waiting for results!

There's a shop I linked in another thread that will do it for $200 if you mail in your TBs.

Lol wow! IPS can setup the TB's on a CNC but that will mean new butterfly's. We will have to figure out the cost vs increase in power vs what just knife edging the stock TB with PnP will do.

This guy quoted me $200 with a 1 week turnaround (including shipping both ways).

Not a bad price with shipping. Actual labor cost then seems on par with IPS. He told me most TB's (they are a GM mostly company) like the huge corvette TB's are at like $65-70 each. So $140 plus shipping for us I'd guess.

Exactly, because it's two of them.. twice the work and twice the materials (includes new butterflies and stuff).

Wait so $140 for IPS with knife edge and PnP, his are $179 PnP but its PnP'd all the way through with a new BF. That's a good cost. Will $39 equal more power, hmmm?

Not bad for 200$
I strongly suggest to do more than just boring those TB

he has another option for those TB which is TB Shaft machining. $35 each.
since you can have quite a bit more flow doing this.

its kind of odd he doesn't have a knife edged butterfly plate though...


This is what I used for the pass few years

In your opinion, as you have experience with bored throttle bodies, will I have any tuning/idle problems if I go this way?

you will need to adjust the idle screw which look to be locktighted very strongly btw.

then if you know what you are doing with the tune. you wont have any problem



again,
I prefer to mention it often, you need a different intake setup other than OEM because you MUST have a bigger intake tube especialy the MAF tube. if you arent doing it right , boring a TB to his maximun as I did , you wont get much of any gain
this is boring 2.5mm out , cut the shaft in half , flush screws , arrow edged butterfly plate.

edit again ,,, if you dont have a very good flowing exhaust ... forget about this mod ! ,,

Can you run without a tune?
No, I don't want max power. Just will it run ok without having weird idle issues and such?

i wonder if my current intake/exhaust set-up meets the requirements you mentioned for actual gains from a TB bore.....hmmm lol

i know my intakes are larger than stock and i believe larger than G3's so i should be good.
