anybody know how big you can bore a stock throttlebody on a 2000 tiburon 2.0L, please let me know if anyone has has an idea or has done this????
thanks

 

You can bore it to 58mm.

 

58mm is correct, however there are ather other things you should know before attempting to overbore your stock TB.
Try searching here and also www.hyundaiaftermarket/old there's plenty of info there. I know a member of ha.com had contacts at a shop which could do fine jobs with TB's and IM's, however I don't know if he can still do the trick.

 

so 58mm then thanks, what are the other stuff do i need to know about??
i'm getting a person to do it for me that runs a shop that does all porting and polishin and boreing out throttlebodys. so what info do i need to know before i do this thanks for your reply pls let me know????

 

Just wondering how much is the bore going to cost you? Does it make sense money wise to do this and not just go buy a 61mm rside or 60mm tigerlilly tb?

 

well for the guy to bore the throttlebody out cost 175 (thats canadian), i have seen the 61mm rside i think that one was over $200 US, but i i have not see the 60 tigerilly one so i dont know how much? what do u think, what would you do???

 

Yeah the rside one is about 250+ US if you can find one. As for the tigerlilly I was mistaken it is actually 58mm and runs about $250 US. So if you can get the Stock one bored up the 58mm for $175 Canadian (thats less in US right?) I would probably say its worth it especially when the rside 61mm one is hard to find now and that would be really your only other option that made sense dollar for dollar.

 

Don't forget you have to buy a new butterfly valve...

 

Good catch. Do you have a new valve and everything already?

 

yeah i think i go with boreing. they guy who is doing my throttlebody includes the butterfly too. i just give him my throttlebody and he bores and replaces the butterfly and any other stuff i need
