what would be a better motor than any k series motor??????? i mean i didnt even pay for the k20a3 my brother gave it to me cause he wreked his civic si. so im just putting money into it. and there no such thing has a sucky motor or better motor its what you do with it. ive seen a geo metro motor thats 3 sylinders running 8 flat. anyway ima build the k20a3 so i can put it on my 91 integra i dont see alot of DA running with k20.

 

did you read my above post??

 

im talking bout the k20 type r cams and i dont have kpro do i need it for the swap???

 

ITR = K20A which is the integra type r in japan..its not an rsx over there
so obviously u dont know about the head and the fact u cant just swap in the k20a cams into a k20a3 head..
also kpro is needed to run the car..or a itr ecu(k20a)

 

t4eg is also talking about the k20 type-r cams.

you really need to go do some research on k20a.org before jumping into a project like this. Trust me, this isn't like b-series, you can't just swap around parts from motor to motor.

 

i know ur talking about ITR cams, u need the entire rocker set from a normal ivtec motor the k20a2 for example and the VTC then u can use ITR cams, and putting it into a eg/dc/da/etc etc your going to have to bypass the immbolizer u could use a ITR (k20a) ecu since it doenst have one or get kpro.

 

Read this post it will give you the info you need How to get A2 cams to work in an A3 Head - K20A.org .:. The K Series Source . Honda / Acura K20a k24a Engine Forum

 

lol goodluck it looks like you have your heart set on this a3, you gonna need it. also about the comment about "what's better then a k motor?" thats like me asking whats better then a b motor? there's a big difference between b16,b17,b18a,b18c1,b18c5 etc. same goes for k20a,k20a2,k20ar,k203,k24 etc. there are advantages and disadvantages to each, you should really take your time RESEARCH the subjects/motor/whats actually involed in the swap and then make your decision on what would be the best motor for what you want to accomplish/spend. dont just build up any k you find and try and figure things out as you go cause you'll end up spending way more money then you have to and getting beat by another k w/less mods and money put into it. also running 12.5:1 c/r you will need k-pro to tune it correctly. on a side note you are correct that its not the motor but it's what you do with it that matters, but unless your some type of baller guy who has nothing better to do then dump alot of money and parts into a motor that is not going to be as beneficial in the end as another motor (say:k20a2, k20a, k20aR) with the same ammount of mods then so be it. again imo just sell the k20a3 you have w/ parts you bought and buy a nice k20a2 for ~ $4k complete swap. buy some mounts (if they have them yet) ~ $600 axles ~ $400 and wiring ~ $350 header ~ $350 and prc (i believe someone correct me if i'm wrong) jdm dc5-r ecu ~ $400 bolt it in and call it a day.

 

just a little bit of RESEARCH turned this up on k20a.org. check out the rating difference between the two.

45 horsepower is alot to make up and w/ the money spent on pistons,cams,rocker,pins,rocker shafts, you could just get an a2 or z1 and have a motor you haven't touched yet making 200+hp rather then 155hp...

goodluck either way i'm not trying to bash your idea or process of thinking outside the box. if it's your cup of tea to be different so be it, just giving my opinion on where the money could be better spent... free bump

 

Apparently he's got a free k20a3 and a teg, I didn't hear him say he's got an extra 5 grand to blow on a k20a. The k20a3 would be a blast in a teg, not the fastest thing on the road, but a fun little project. I know because I have an ep3 with I/RH/E and I have a great time with it. There are also supercharger and turbocharger opt's for the a3. I say go for it bro, more interesting than the run-of-the-mill....everyones-got-it b swap, and it's got more tq. Sux that every time someone mentions the a3, people automatically bash it just because it's the popular thing to say. Besides if you really decide that you want the n/a vtec fake turbo lag and a couple extra ponies, you could always get an a2 head and k-pro later down the road and there you go. G-luck man
