I took a quick look at Wikipedia and didn't realize how many different versions of K there are.
is the jdm ITR k20 still good?

I was thinking a full swap where I don't have to do any internals(im good on that after this b series failure just want to drive the car)

the jdm k20a is about 5k plus the accessories etc that would probably cost arm and a leg


what are some other good bang for the buck engine

I know theres the k24/k20 Frankenstein but I don't really want to do that just yet

 

What chassis are you putting this in?

 

do a straight k24a2 swap. you can find good condition longblocks for 1500-2000 all day. you can probably pick up most of the other stuff you'll need for the rest of what that k20a costs.

 

or just buy this

you'll love the extra torque in these lighter chassis

 

this. you can throw in a set of cams down the road and make gobs of power.

 

I was thinking into a 4 door integra
I like 4 doors now that I have a kid to drive around.

hopefully he doesn't blow up when that vteK hits
my gsr made lil kids cry before

 

Do a k24a2 swap. My 05 motor with race header put down 201hp 171tq off the k-pro base map. How can you go wrong with that for a $1000 engine.

 

I just got rid of my semi-built k20a for a k24a2. Tq is irreplaceable on a k24

 

Rdriver is that to WHP or crank?

the thing is. I like RPMs I fn love that sound of 8500rpm

even b20 with its nice midrange doesn't do it for me. I was more happy with a b16 its gutless but when it revs up its soo damn smooth its music to my ears.
b20 is nice to merge in traffic cuz it just smashes instantly but then its like well that 6000 rpm comes up quick and then everything falls on its face.

most of the time I wasn't even racing anyone I would just find an straight road with no cars and smash through 4 gears.
with b20 I don't even rev it past 5500 that's where vtec supposed to

>>>>engage<<<

 

i used to love rpm's too until my motor let go at 9k

 

yea that's the downside.
u mean u still like rpm it just got expensive for you and for me

 

my current motor only sees 8100. can i rev it higher? sure. but power flat lines at 7500 so there's no point.

 

so from Wikipedia I gathered that

K24Z6 would be the best choice fro k24
and

k20a from a jdm ctr would be best choice for k20

 

the best choice is a k24a2 from an 06-08 usdm tsx. readily available and cheap(ish)

 

not meaning to thread jack but if u just swap out cams on k24 u make all kinds of power ? if so how much ?

 

damn

 

some of problems eith the z variants is the drive by wire throttle, ecu, engine harness and the newer k24zs have redesigned oil system that puts the oil filter smack in the way of a half shaft. typicaly you want to stay 08 or older.

again 06-08 tsx is the best oem k24 to keep oem and simply drive

research crank position sensor and use of the crv post mount

 

Why not just build a k20a/z with R cams for cheaper?

 

why not a k20a2

 

One of the best K motors out there is the k20z3 found in the CSX Type S and the usa cvic si or sir, not sure exaclty as im not in the states.

There are only handful of k motors that have a three lobe cam for vtec. the k24a2, k20a2 and the k20z3 are the top threewith true vtec

 

Do a 2.4L and thank me later. There's no replacement for displacement and it makes life a whole lot easier.

 

Like most stated the k24a2 would be the motor to go with. Won't regret it. Or if you can get the 09 tsx motor is had a bit more compression.

 

Along with a single exhaust port and vtec on intake cam only

 

K20z1 and K20a from and EP3

 

you new crop of noobs are terrible
