Has anyone changed out there throtlebody. I am looking at porting mine or buying one. Anybody have an extra??

 

rx-8 throttle body

 

it seems if you want to keep DBW going with the RX8 TB is the only choice. If your converting to cable you have limitless options.

 

And you still have the same size hole in the intake. Unless you are going to change that then this will gain you almost nothing.

 

PM me what you wanna pay shipped

 

rasta pm me i have one for cheap! that i repaired.

 

trade you a exhaust cam (if you have one) for a throttle body?

 

you also need a adapter plate and i still havent seen a TC with a rx8 TB. its been said and they used to sell the adaptor plate but i dont think they sell it anymore.

 

Done! PM me for my cell lets do this

 

I have an intake

 

An intake manifold or an intake tube? Pretty sure the hole in the mani is the same size as the stock TB , which is what I was referring to.

 

to get the best gains IMO.....descendent intake mani, cut off there throttle body flange and replace with a custom flange that is bigger to accommodate for the rx8 TB

 

can u use the rx8 tb on a f/i tc or just a n/a?

 

never been tryed from anyone one scionlife i dont think.

 

really.....

thats like asking if you can use emanage on an f/i tc or an n/a tc.

the applications are limitless as far as this matter goes. you will see gains for both apps with the rx8 TB. i can see it having more gains with f/i though but if your going for 200hp na then it would also be nice.

 

Its a decedant racing one it might be I will check it out.

 

this guy has a rx8 throttle body.

Rasta... it would be pretty clear if it was the manifold or just an intake... you would have needed to remove the throttle body and then remove the intake manifold, as it is the part that bolts to the head.

What everyone calls an "intake" is just the tubing running from the throttle body to the air filter.

If the hole in the intake manifold (the part the throttle body bolts to) is not made larger, then the TB will net you nothing assuming the hole is the same size as the stock TB, which I am pretty sure it is. Actually, you are potentially doing nothing more than creating more turbulence at the manifold.

If you have an aftermarket intake mani and the hole is larger than stock, then the TB will probably give you some gain..just not a huge amount.

 

^^ great find

 

if your going to hack of the flange of a sheet metal intake manifold, you might as well just put a 90mm Q45 TB on it and snag a cable from the junk yard... lol. wait.. only i would do that
