I have a f20b and i was planning on running a 70mm throttle body once i got my euro r manifold. i also planned on match porting the manifold to the throttle body. would it be to much? my setup is mild with skunk 2 stg 1 cams, an-r header, rs-r exhaust, spoon air filter, hondata tuned with 310 rc's. let me know

I wouldn't unless the head was ported and polished.

 

from what i understand the f20b head has a more smooth port casting and a valve job as compared to a stock h22 head.

If i recall correctly a f20b motor is a Euro R motor. So you dont need a euro r manifold, the throttle body could help out. Stage 2 cams would be better in my opinion because the f20 comes with more aggressive cams so the stage 1 ones may not provide a noticable improvement. AN-R header is a nice header (debating on getting one myself). Instead of getting a spoon air filter why dont u just get a K&N it'll probally be cheaper. Also why get 310cc injectors? I am sure the 290cc are more then enough and the extra 30cc isn't really worth the money. Other then that you seem to be on the right track. There are other alternatives to hondata aswell but it's all in what you and your tuner are comfortable using. Good luck

 

f20 is the sir accord motor that has a manifold much like an h22 the only differance is a 3 wire iac. the stock cam is a type-s and now that i look back i wish i would have got something different. i got a good deal on the spoon filter so thats why i have that. as far as the injectors i didn't want to wire in the resistor box nor did i have a resistor box so i opted for the 310's. maybe i'll make more use of them later on down the road. anyone have an opinion on the t/b?
