alright just got a hondata s300 a obdI a fuel rail 310cc injectors just orderd a blox intake mainfold. my 1st question is im gonna get a throdel body also but what size??

1.66mm bore
2.68mm bore
3.70mm bore
4.72mm bore
5.74mm bore
6.76mm bore

when i take the car im planning on towing it to the place its about a 1 1/2 hour drive ( this is the 1st time im getting a car tuned) or would it be better to drive it?

 

List your setup. No one can tell you what you need without knowing your setup

 

oh im sorry lets see pretty much everything internaly is stock just have some bolt ons, intake, headers, and exhaust.. and just orderd a intake manifold

is this what you mean by my set up?

 

If that is the case, go with a 66mm.

 

you can drive it over there but car will be extremely hot so just tow it but i would get a 68 so i leave room for improvement i woulnt want to buy another one later they aint cheap

 

alright so what about when it comes to building the motor internaly.. what size should i use for that??
