so if you swap your A2 block for a k20A block will it be faster?

 

yes.

but it's really not worth it unless you're baulin out of control and have all the time in the world.

the two are extremely similar. get some new cams, i/h/e and you'll be making good power.

 

id like to know also. does anyone know the real differences between the two? i know the transmissions on the k20a are much stronger and are race built...different cams....

 

sorry but what is i/h/e thanks

 

what cams do you recommend

what are you looking to do with the car? thats the biggest/first question
basically, if you have a k20a2, keep it man

 

just build the a2 it will be cheaper and faster. Its not a big difference as say a gsr and type r engine. They are both very similar just the k20a is more built for racing.

 

sweet thanks im probably just gonna be using all motor. gotta stay true to vtec

 

new to the k20 motors which is the difference between k20 and k20a which car they belong to. and why the 05-06 rsx type s has more hp than the yearsd before

K20z1 belongs to an '05-'06 RSX Type-S and the K20a belongs to the Type-R model.

I believe they included Type-R cams and a few other things, but I'm not quite sure. Search for more information.

You are correct... they are typeR variants... assuming they are typeR cams. k20z1 also has shorter gear ratio then the 02-04. Other then that the rest is aestethics.

I believe the '02-'04 models have a 4.4 final drive while the '05-'06 have a 4.7 final drive.

 

I think he asked the difference between the k20a and the k20a2? anyone know?

yes it does but the 05-06 has a lower final gear ratio.
Lets say you are at 3000rpm at 60mph with a 4.4 now with a 4.7 you are now at 3300rpm at 60mph

that is why i prefer the 02-04 tranny, especially for boost

engines can be

 

i have a 99 nbp gsR and im going to sell it because i want a nbp 05-06 rsx type s. i want to boost it depending on how much boost i run and what i do will the car be oil change and key start worry free. or should i just keep the gsR

Huh?

 

sell your swap for about 3200
purchase k20a swap for about 5600

for approx 2400 you get:
better header
better cams already installed
better valvetrain already installed
better/higher compression pistons already installed
better intake manifold already installed
better/smaller diameter crank pulley already installed
better/higher final drive already installed
better/more aggressive gearing already installed
better differential already installed
better valve cover LOL
better dip stick LOL
better overall powerband
better than aftermarket upgrade options reliability issues (lots of people experiencing timing chain slap and oil pump failure with aftermarket cams)
better/higher resale value of swap
better/matched ECU for your engine setup (PRC ECU)


seems like a decent deal to me.

 

Yeah but i want the newer body style vehicle. i do have a question about the k20a and the k20z1 in the 05-06 whats the big difference. i also think that i could just purchase the type r lsd and the final drive or is the type r tranny better over for boosting that is.

 

in 05/06 tranny is the same as type r w/o lsd, The FD is 4.7 in 05/06 compared to i think its 4.3 in 02-04. the z1 has more hp, type r cams and i think something else im missing
