I'm about to order a big throttle body and don't know if it would be good for my settings, if so which size and eventually brand or do i have to stay OEM.
I'ts a 03 AP1 whith MUGEN ecu,header,catback,airbox,all cooling stuff.also test pipe,4.77 gears,light pulleys,clutch and FIDANZA 8lbs fly.Sorry if my english is average i'm french so it's not that easy.

 

All of the regular throttle bodies will fit: Skunk2, Omni Power ect. If it fits a B-series Honda(minus the GSR), then it'll fit the non-DBW s2k's. However you can only bore out the manifold to fit a 70mm throttle body.

 

SOS throttle body is a good option too: http://scienceofspeed.com/products/e...throttle_body/

Power gains backed up by dyno charts and no mention of port matching the intake manifold (for what it's worth, YMMV)

 

That's because the outlet is only 64mm, only 2mm bigger than OEM.

 

I read someone installed this after a port and polish with this TB helped gain torque/hp as well.

 

A 68mm tb will be a perfect bolton it's perfect portmatched to the OEM intake Mani.the stock tb is undersized.I'm on stock ecu and a bdl 68mm and it was my favorite mod.

 

The only difference you will see with a larger throttle body is the increased throttle sensitivity at partial throttle. The slightest throttle gives greater response.

Increasing the diameter from 62.5mm to 64mm will make a major difference. I drove a 64mm for 4 years with a 8 lb. light weight flywheel and totally enjoyed the experience. Parking on steep hills took all of my attention and a little revving to complete the task.

I'm driving a 70mm BDL now and it feels good. I am boosted.

 

Good to know. I should be receiving my Professional Products 68mm here soon!

 

Thanks guys for all your infos i much appreciate.I think i would go for a 66mm or 68mm.

 

66 is barely bigger than stock.stock id is 65 tappered down to like 63.the 68 tapers down to 65 to match the intake Mani.a
