I suck with all the engine codes, which prevents me from researching this, but has anyone swapped in the Si engine into their Em2? A guy on a local forum is running 300 hp in his si with a cybernation kit, and I just saw one of these engines on ebay for 1400.
As I was reading through this thread I was wondering why nobody was suggesting this. The EP3 engine (02-05 si hatch) is the K20A3. Stock, it puts down about 135-140 hp to the wheels, but you can get these engines relatively cheap compared to the A2 and people have had amazing success with turbos on them.
the cybernation stage 1 turbo kit is going for $3695 through ephatch (that's $100 off) right now and will get you about 260hp to the wheels.
also notice this statement, "The B-Series motor DID have a power steering pump, and the A/C torque mount, so factor in 5 lbs or so on top of the numbers below.."
and if you check out SleepinEP3's post, in this thread, he states that his D16y8 (from intake manifold all the way to oil pan) weighed 300 pounds. the d17 isn't much heavier than a d16 and definitely not as heavy as a k20 or any b series.
in a nutshell ... K series = heavier than D series

doesn't the k20a3 have a different compression ratio compared to the a/a2. something along the lines of it doesn't respond too well to boost? either way, i'll pay the difference to run an a2 over an a3 anyday. (if i ever have enough $ to do that to begin with).

the A3 responds much better to boost than an A2, so if you want to run turbo on your swap, get the A3. If you want to go all motor, get the A2
So when we talk about building up the internals, what exactly does that mean? Im somewhat of a noob to turbos....Im guessing pistons and rods, but what besides that? I really wish they had a SC for the D series, but as of now it looks like Im gonna swap A3 into my 04 next summer. I dont really care much about track times or racing, I just want some more power to get around in my daily driver. Would the D17 turbo suit my style? That would be my first choice, but everyones saying that even with low boost its not good for an unbuilt D17...I really just wanna be able to roll up on my friends and blow off lol.
I will never Turbo or Swap my D17 Civic.
I've just completed my I/H/E p&p head, bored TB (only got Valves, Retainers, Springs to go) and within the next few weeks geting it dyno tuned for a 75 WET SHOT!
I will keep the car untill the engine has just about had it! MAX 2 YEARS!
Then get a S2000 and TURBO THAT!!! That cars worth a TURBO Setup!

Internals commonly associated with building for boost are typically turbo, forged, lower compression pistons w/ thick ring lands & some nice forged heavy duty connecting rods like these:
These are for a Toyota Supra TT though, going in an IS300. Able to handle up to 1,000 RWHP.
Some people also choose a turbo profiled camshaft. They also do valves & retainers as well, but the basics would be rods & pistons.
a TURBO D17, with this :
installed to make this:
actually makes a VERY nice car. Very fun to drive and pulls quite hard. I loved driving my turbo'd D17. It was the 2nd most fun car I owned to drive. My 1st is the car I own now.

i hate to revive an ancient post, but i was having this continued debate with a member just last night. He was asking me if its better to do a D17a2 turbo or an K20a2 swap.
And from personal experience (i attempted a swap last year), it is alot easier and cheaper to go with a d17 turbo, then it is to do a k20a2 swap. Mind you i agree that when its all said and done, you can get alot more out of a k20a2 or possibly a k20a3 turbo.
But if money is an issue, i definately recommend a turbo setup
I need boost.
