Hey guys i have a 01 Integra with a JDM B20B,Greddy Headers,Greddy down pipe, and a cold air intake. I was thinking of doing a B20Vtec but some ppl have told me not waste my money and with that same money go K-Series. Any suggestion or opinios ? Thanxz

 

the difference is a zero, 500 or 5000


best deal imo is the 96-97 itr engine for 2500 shipped. reliable, powerful and easy to install. a k swap is great if you have the cash and offers both displacement and a reliable platform. it really comes down to what you can afford, what your power, mpg and reliability goals are & who's doing the work.

 

I couldn't haven't said it better.

 

1. 2 diff engines,specs,design,power potential.

2. 2 diff price ranges for just to build,mod or swap.

3. not even a option or considiration of what engine should be done if the funds are there.

until the k swap become for cheaper ppl will continue to do lsv.and h2b's. proven power and waaaaaaaaay cheaper then any k swap

 

really you can get a itr spec for that low now and days? where at?

 

jdm engines corp off the top of my head, if you want the ecu and j4d lsd transmission add 1000

 

Wat would be the BEST vtec head i could use for my B20 ?

 

did you miss the flow chart? the pr3 and p72 flow nearly identical. use whichever you can find in better condition. 90% of the craigslist vtec heads are shot and in need of new LMA's, guides, valve job and possibly have damage to the cam caps.

 

You could also go the junk yard route instead of buying from someone who knows the performance market value of these engines.
K-powered cars have been on the road plenty long enough to find wrecked ones at a decent salvage yard. I say go out and search the junk guys' lots. They may only want a grand for the "almighty engine of Jesus" K20, which to them is just another motor.

 

The local junk yard had like 8 k24a4 for $400 each w/3 month warranty. I walk out the door with a 2005 Element k24a4 w/ 60k for $350 bucks. Runs like a champ. Rsx base tranny $385 frieght from SC...u get where im going. The deals are there if u know what your looking for. http://www.k20a.org/forum/showthread.php?t=63867

 

a k swap is not worth it IMO. some members like to put a K swap into their cars because you can say "i have a K swap in my car". yes they make awesome power and yes they are well built engines, but you have to pay a pretty penny for them. i think an ITR/ B20 Vtec swap or build would be more practical and make just as much power.

 

yea thats wat i was thinkin an ITR head and cams

 

imo best use of money and practicallity, a pr3-2 ctr head and an itr mani. i was running that on my b20v and it pulled on k swaps

 

dont waste your money on a itr head, anything that says itr ppl automaticly think its gold and want a arm and a leg for it. Buy yourself a pr3 or a p72, get some springs and retainers and some pro2's. If you add a good tune with hondata or something your looking at around 210 whp. with the right bolt ons.

 

soo a GSR Head and Cams Ported will be guud ?

 

If you're going to go K-swap u might as well just buy a used Si or DC5. a full kswap is over 5K

 

Did anybody read this guy's post??

You don't have to buy the swap from www.awesomeJDMshit.com. Go out there and dig around a little. Only suckers pay retail.

 

K series is DEFINITELY better then a Bseries, ive heard of B20's that were turbo'd and ended up blow up because its essentially the bored out version of a b18, i believe... Frankenstein FTW

 

yea that would be a nice set up and if you wanted a little more put some high comp pistons in and a nice tune would probably put you around 220 or so. only bad thing about the b20 block is the symise cylendars cause them to get hot and the sleeves can crack.

 

and is it expensive to put other sleeves ?

 

Dont waste your time on a b16/ITR head, and instead opt for the Gsr head instead. It will give you a bump in compression due to its smaller combustion chambers. The pr-3 and p72 heads flow nearly identical.

You shouldnt be worrying about porting just yet. With some good aggressive cams, some high quality valves and valve springs, along with the right combination of high compression pistons, you can have a very nice setup for the street.

 

You are essentially comparing apples to oranges, and its not a good comparison. The OP never mentioned forced induction, so no need to bring other outside factors into this, as they are not relative to what he is inquiring about.

 

That is exactly what I was going to say. All the accords, tsx's and elements have had these engines for awhile, and have become very common in the junk yards. A stock k24 is going to make around the same HP as a b20v, but with more torque. Seriously though, when I get sick of my R motor Im going and picking up one of these cheap k24's, and building it.

 

A decent sleeving job will cost about 500-1000 for the sleeves alone, plus whatever labor the shop charges you.

 

and the place doing the sleeve job better be accurate. if they are off it will drastically shorten the life of the engine due to being out of alignment. personally, if i was going all out i would use the dart block.
