from what the guys in the US are doing, they seem to make max power around 6800-7100rpm... so keeping my 7400 rev limit should still be fine

looking forword til you finished the project. interesting what type of cam you using and where did you get your head from. i want to do this for a long time, just can't make up my mind. nice job

im going to trial a set of ITR cams and see how they go...

i got the head from a guy in the US on K20A.org

heres some updated pics, i finished porting and polishing the throttle body, its now 68mm at the pipe inlet, 64.5mm at the narrowest, and 66mm at the rear...

How much is it to bore the throttle body?

How much is it to bore the throttle body?

i purchased a throttle body off a J32A3 (2004 Acura TL)... theyre already DBW and they are direct bolt on (apart from having to weld up the idle bypass on the RBC)... stock they are 64mm (compared to K24A3s 60mm) which is an increase of about 12ccm

i bored mine out a lil more (especially on the intake side) and polished it myself... the stock surface was fairly rough, but as you can see now, its very smooth...

thank you

thank you

i did the bore myself... so didnt cost me anything but time

68mm was pushing it around the top... which is why i only went to 66mm on the other side... going to 70mm probably wouldnt make any differnt with the 64mm butterfly because u cant bore that bit out anymore...

and the job is perfect (you can see you reflection in it!)

[Suntzu]

Id love a bigger TB. how did you do it and how much to get the butterfly fabed?

gainage?
