its a port and polish...

port and polished throttle body...

so there is 2 of them? or you get 2

i think there is one.... i dunno, would this help performance?

Porting/Polishing the throttle body is a viable enhancement. Of course it works best in combination with other performance modifications. Every little bit helps.

In all honesty, besides whether an upgraded TB is helpful or not, I would not buy engine parts of Ebay.

As long as its not some spoof eBay account it looks like this is BDC Motorsports out of Texas. Last time i checked they were legit :dunno:

They have an RX8club account around here some where -- send them a PM.

I'm not sure to the effectiveness of the PPTB but i dont think this would classify as an "eBay part" like we're used to.

The person selling the TB is a member here and has offered this service here. There is a thread on it as well :)

Yes those are BDC's. Legit.

Now as far as power gains,,,,,

Yep...Brain Cains stuff...he's a good Dude !

wow, a legit find on ebay? That's rare.

+1 on going through the forum instead of ebay for the purchase though.

I wonder if this is similar to the larger TB's that I saw on the hyper rev rx8 catalog. dog fight pro, re plus, crk and luck offer an aftermarket TB that are 20mm larger than stock.

also, I've bought a few engine parts from ebay that are made by reputable manufacturers. and they all turned out to be fine. for example, I got an updated manual starter for a little over $100 (brand new) and it's still on my car until now. And so are the sparkplugs on my car, ebay specials fro $50 shipped. You just have to be smart enough to differentiate the legit parts from the bogus parts like the grounding kits, intake vortex generators, tb spacers and fuel line magnets.

Of course I'm legit. :) I've been in business for 7 years and have been doing throttle body work for that same amount of time albeit obviously not with the Rx8 ones. That's a more recent deal. I've got about 8 or 10 of them I've done out there and everybody that's got one has posted the exact same results and have said they were happy with them.

There's two up for sale right now; two auctions going at $200/ea. The breakdown of charges is $150 for the job (as I would normally charge someone who would send me theirs to do), $50 for the cost of the throttle body itself, and $0 for US ground shipping.

Dillsrotary, generally I would agree with you about buying engine parts on eBay. I get folks who IM me fairly often asking me about the condition of used rotors and rotor and/or iron housings that are up for sale and whether or not I would buy them. With stuff like that I'm very picky. However, I think in this case it's a moot point.

hey bdc has anyone done any dynos of the gains?

Side-by-side ones? Nope not that I know of. I'm not surprised it's the case with these though because I don't have too many out in the field yet. One customer of mine did one with one of my Turbo II throttle bodies about 4-5 years ago. As far as I know, that's the only one anyone has ever done with a before and after.

This mod WILL give the car a good bit of kick, even a stock one.

B

Someone should fall on this grenade, buy one and post feedback....... not it ;)

It's not smoke and mirrors and there's no false claims, Jantzen. It's a cheap (yet cost-effective) and easy mod that doesn't require hacking the whole car up and it yields the benefits I and others claim it does. Perhaps you should send me yours and I'll prove it to you. :)

B

Oh i have faith... i'm just looking for some more info because im curious. If my mod list wasn't a mile long i'd send you my throttle body tomorrow ;)

It'll only add a couple more inches...!

You should get it :D

I'd do it... if l was in usa

You should get it :D

Hey i didn't start this thing! Tell the OP to get it :lol2:

Brian - I read a PPTB would bump up the idle. Is this true in all cases or just some. I am having idle issues and i'm running out of solutions so i might "need" this ;)

Jantzen, I haven't seen that happen with the idle on the ones I've done locally. If it has, it's been minimal and/or unnoticed by anyone.

I still think you need it. You'll like it. It gives some zip to the car and it doesn't take too long to swap off.

How much is it to normally ship something from Aussie to the USA via air mail? In my ground shipping here from state to state, I normally factor in about $15. If it's not much more, perhaps we can work something out.

So Brian what is the turn around for this service?

Normally I can get it out the same day it shows up. For you since you're in San Antonio, figure 1 day to ship.

In Japan, Fujita Engineering has been doing Throttle Body Mod for RX-8 for years. polish it and enlarge it by 2mm.

Does it help? hmm, dunno, but their Touge RX-8 is a monster car.

They're still up on eBay. If anyone wants to see some photos of the actual ones, let me know and I'll post 'em up.

B

yeah i want to see photos , and i can ship mine out for 150 bucks and back to me?

yeah i want to see photos , and i can ship mine out for 50 bucks and back to me?

Ship it out for $50? I don't understand. If you were to send me yours, I'd charge $150 plus return shipping of about $15 (figure $165).

I'll take a couple photos here in a bit and post 'em up.

I would never buy anything automobile related on ebay. There's been cases of customers getting royally screwed by the seller. I would say get the real thing from a distributor, even though it would be more expensive. GL

There are also many distributors selling the same thing on eBay cheaper then they are on their own website.

If you know what you are buying and DO NOT use eBay to LOOK for items TO buy you should be fine. Just cover your ass as in any other online transaction and you should be fine. E.g, always use a CC with Paypal because Paypals claims process is terrible.

Once again do not use eBay for research purposes!!!

There are some good sellers on ebay but you need to know who you are dealing with. In this particular case the seller is a member here and from what I can tell has a very respected business in the rotary community.

I've still got two up on eBay if anyone's interested in 'em.
