a lil more power???? a k20a will give you great power and yes it will be worth it and k-series is only gettin better.... ask around or search because some people have done it and you should ask them. 1000 seems like a scam for a k20a mtr

he said a K20a3 which is the base RSX/civic si motor.

i think as of now the K20a3 is a good option since it is a lot cheaper than the a and a2.
id rather turbo than get the K20a3. the a and a2 are different stories.

i would always rather have N/A powerband then a lagging turbo in my city, the weather is always changing in calgary, one day it sunny hot, and next its COOLLLLDDDDD and snowy, hehe, so K20A is a good option, but really its just too hard to save that kind of cash for the A2! so i would sayyyy f the K20A3 and just boost the B*TCH

the cost of swaping a k20a3 and a k20a2 is the same and costly. If your gonna spend that much money to swap then it'll be better to save for a k20a2. the 40hp is huge then again 127 to 160 is huge as well. i think u should ask yourself if you want it now or wait till you can afford a k20a2. I've seen k20a2's go as low as 3k, so its up to u

k20a3 is good if u plan on boosting it.

well.. take this into consideration and i already have parts coming in to do it..i am swapping in a k20a3..i also have a k20a2 head which is the type S coming in... basically the only differnece between the a3 and the a2 is the head.. the a3 has 2 intake lobes and 1 exhaust while the a2 head has 2 intake lobes and 2 exhaust lobes..so if you can find a cheap k20a3 then down the line swap out the head.. i have seen the a2 heads go for as cheap as 500.. but if u want to build your head find a k20a2 head without the internal parts which should be around 100-200 as i have found... then go buy some skunk2 cams and valves and springs and retainers and all that good stuff

so the only difference is that one exaust lobe? how does that make such a difference in the a3 and a2?

Personally I think it is definately worth it. And anyone intersted in doing a K20A3 swap, can buy mine for cheap with an itr six speed transmission.

Hey i have a A3 out of a base RSX and i love it, I just made up for not buying the type S by turboing the A3. Its a very good motor and has lots of potitential.

Hey lucky13matt you should drive up to the Ga line and ill drive down and meet up with you one time. I would really like to see another A3 swaped vic.

for a G id get the swap. its alot better the the d-block and responsed to mods very good. i need to find a deal like that.

Like everyone else, I would say that it depends on what your performance goals are. As everyone else says, A3 would be better if you are going to boost and the A or A2 would be good if you are going N/A. You can boost the A or A2 but they already have high compression. Also, you can always swap the A3 head for the A/A2 head later down the line and upgrade the ECU.

Get the A3! why... swap an a2 head on there, K Pro = 240whp!!!

if you try and rev the a3 block w/ a swapped a2 head to the 8600 rpm limit that is imposed with hondata #4 (i think) you'll have rods everywhere at 8000. There is a BIG difference in the bottom ends in those engines. Just get Hondata for the a3 and you'll still get 170whp with boltons, in a vic that'll whoop a stock type S b/c of weight differences.

Anyone who knows anything about boost knows lower compression engines respond better to high boost levels. Like xproductionz said the motors of a k20a3 versus the k20a2 or k20a basically come down to a difference in cylinder heads. So considering the price of a k20a2 somewhere around 4000 compared to a k20a3 1500, it would be a good start. Do the k20a3 swap, then boost and head swap later. Yeah the guy above is right about the revving potential of a k20a3, but revving is for high compression engines as boost is to low compression engines. What's a little sacrifice of revving for a high horsepower boosted enigne. Forgot to mention you probably can't boost too much, due to the k20a3's shitty crank and rods.

GREDDY t-kit for K20a3 w/o FMIC advertised for 240 whp without any internal mods. longer gears in a3 are better for acceleration w/turbo.
I think for 1G + Homemade t-kit = 220 whp with no sweat.
Good daly ride at the end.

I have been running the options through my head and I think for my own project the a3 is right up my alley. I dont too much power just more and for my budget the a3 makes more sense. I thought about building my d17 for higher boost but saw that would be about 3k without adding the turbo to it. Then I would still have an automatic tranny to swap about another 1800. So I would love to get a complete a3 and do the whole thing for less than the 4800 it would cost to bring my d17 up to par.

hey i got a k20a3 motor i will be disecting thru the winter an hoefuly putting it in in spring how much b.s. do i need to worry about when putting it in? like cutting grinding that type ****.thanks

I have a d17a2 in my 03 ex, what all did it take to do the swap? Wondering because my engine is about done with its life.

qnzboiboi

let me know if you find out the cost.. I just blew my d17a2 I was thinkgin about buying a K20A3, But I havent had any luck finding the cost of the build

brotatochip1000

You can find used k20a3's for like $1,000 shipped off ebay and other sites. I am currently in the process of swapping a k20a2 into my '02. I have found it is much easier to just buy a donor car
