i have a k20a3 that i am wanting to put im my 91 ef.
i know i will need to convert to OBD2, and get mounts and hydro to cable conversion, axles, etc.

is there any thing else major that i would need.

i am also wondering if i can put in a different instrument cluster, and if so which one....or would it be cheaper to make my own with gauges..

anyone have any links or websites strictly for this build.

 

k20a.org or com

i think u need a shifter box too

mine as well get a good header now i can imagine it would be a bitch lateer

 

my homie is putn one in now, gota order shifter plate from a eg and mod it a little but he also bought a hondata ecu and bought a wire harness, plug and play, but u will put some money into this before its done, but its sick, round 220hp to the wheels on a stock k20a3, bout a 12 sec car with stock build fffuuunnn, k20a3 is the next swap ima do in my ef hatch, but its alotta work, hes been very frusterated over it

 

i just mainly need a parts list.
that way i can get prices and go ahead and make a plan on how i am going to approach this.

 

K20A3's are only 160hp. They are a DOHC motor with Vtec only on the Intake Camshaft. In otherwords, DOHC with SOHC Vtec. Still could be a good motor but I highly doubt 220 hp out of a stock one. Maybe a K20A2 type-S but not older si.

 

with in that last year or two there has ben many thing discover about the a3, like running a2 cam and rocker for real vtec witch will up the hp about 30hp, or you can switch the pins around in the rockers for vtec killer and use a2 cam this is also about the same power as k20a2, my point is that the k20a3 is not as crappy as i thought, i picked up an extra k20a3 with a2 cam for future project

as for parts list this what i have
hassport mounts
dss axels
rywire harness
jdm itr ecu or us ecu with hybrid bypass or kpro
hybrid racing shifter box
ktuned header
ktuned 3 pulley kit
ktuned fuel rail and fpr
have to move brake valve
have to bash rear x member
have to weld passenger side mout

here is a good link with great info on this

this is exactly what i needed. thanks for the link.

another question i had is can i still have a/c lol, or heat?

 

I have seen some guys on k20a still using ac, but u will not be able to relocate your altenator so u will have to cut the core support and headlight alittle for clearance and make custom lines, as for heater just hook up the line but note that the out let's on the k20s use large hose the the ef, ktuned offers nice hoses that accommodate this

 

hmm i see.
so here are the options right??

AC=mods and hackup a light and core support.
NO AC= Alt. relocate and less money.

i was also wondering about the intermediate shaft as well.
do i have to get one specifically for EF to K series?
What did you use.

and yea i already have a shopping cart list on Ktuned.
