So as the title say K20 or B18 swap? Have you had both? Or just had a K20A2 or B18C? From your experience what would you go for? I plan on swapping to a 2000 EK4 hatchback. I have a B16A2 but I'd like to have more POWER I'd like to achieve the 250-300Hp and for the budget, I have the money to buy either one of them I also know that K-Swap is more expensive. Could you tell me what I need? What can you tell me?

What ya need, is to do research. This has been covered a million times. Have you googled the title of your thread? Just boost the b16. I can help if you want to go the route I mentioned for 300whp and 190ish tq with a b16

I was expecting a reply like yours to do research more on this matter Believe me I have spent hours searching on google the title of my thread. I have read some saying that a K-Swap makes the car handling different and the B18 being an easier engine to mount on a EK since it's a B-Series I won't be spending as much money on swapping the engine, more like a plug and play (the B18). This is some of things that just came to my mind as I was writing this, I have search, alot! I'd would just like to know your experience with these swaps.

What you need to do is to start writing down the pros and cons and prices of whatever swap you are looking to do. This should help you objectively pick which one is best for you. All the info is out there, you just need to spend more time researching. Here's the first link to get you started: **SWAP PARTS LIST: The thread to end all the questions.** - K20A.org .:. The K Series Source . Honda / Acura K20a k24a Engine Forum.

From my perspective, having driven both a B18C1 and a K20A, the K20A is a better engine. Shifting is smoother, torque is there when you need it, and it's just as reliable as a B series (of course it's a Honda). More expensive yes but you gotta pay to play. Here's a dyno graph comparing a B18C vs K20A: B18C-R vs. K20-R (Shawn Hilliers) dyno, same mods on both - K20A.org .:. The K Series Source . Honda / Acura K20a k24a Engine Forum

I was in your shoes a few months ago. Deciding between k series vs JDM b18 itr vs gsr swap. I went the k series route as you will never look back and need to upgrade.
A JDM itr swap actually costs more but the k series swap components cost more and its a little harder to do. A stock k series motor has endless routes. Boost it or keep it na, it will be superior to any stock b series motor. And remember, more tq and better technology.

Thank you for the reply, I'm seriously thinking about going K-series once I finish restoring my EK.

Just like everybody else stated, the b series is going to be easier to install, but the K series in the long run will be better for power once you start adding mods.

Since your goals are so low (250-300), don't waste money on a swap. Just keep stock internals on your B16 and use quality parts to build a nice turbo set-up. This would give you solid and dependable performance on budget. This is the smart way to reach your goals.

250-300 WHP is do-able via a N/A K series...but it's fairly expensive. The best models to start with would be the K20Z3, K20A-R, or the K20Z1.

However, a K24A2 would net easier paths to that power with a lot more useable torque. K24A2's are everywhere and they're CHEAP. A 06-08 TSX engine is what you want. The downside would be the lower rev range...but the upside is the huge ribbon of torque and the willingness to make power.

I would use any of the above K swaps with a 06-11 Si trans (preferrably the 08-11 model), or an ITR/CTR trans. They all come with LSD's and desirable gearing if you're keeping it NA.

The K swap costs about $8-10k++++ in parts to do it correctly.

Turbo'ing your B16 with quality parts will net 250-300hp and it will be a few grand cheaper. You'll need all the same auxillary parts you'd need on a K swap to make that much power...a clutch, radiator, etc.

You're going to have a VERY hard time making 250-300 WHP out of any N/A B series. I would say if you need a streetable engine...it's almost impossible. B series race motors make that much power via an abbreviated life span and a LOT of money/loss of driveability.

I've actually started looking into the K24A2's, everybody that has them say there is much more torque over the K20A2's and I've also seen that they're cheaper engine. I'm not actually worrying about swapping engine right now as I'm restoring/rebuilding my EK. If everything goes well and if I have the money I'll most likely buy an engine next summer and enjoy the B16A2 a little before doing so. The car won't be a daily.

Another option would be swap in a b20 block or get a b18c block sleeve it and do ls crank swap and forged internals. That would raise your torque. I debated back in forth between going k or sticking with my b18c5. In by the end I stayed with b series as I couldn't swing the budget for k. Like stated figure out your goals vs your budget

I'm going with the turbo your b16 idea, or you can go h2b; the hseries/f20b motors aren't expensive and you can make good torque and hp for a daily driver..You're not going to make anywhere close to 250 unless you do some serious modifications

250-no
300-yes

Plenty of guys DD or have VERY streetable 230-250whp 2L B's which are much cheaper to build and swap than a K.

I had a b18c1 swap with bolt-ons in my eg before. And my k20 swap with bolt-ons blows it out of the water. It just keeps pulling on top end where my gsr swap felt like it hit a wall up top.. But since you already have a b16, like the others suggested, you can just upgrade that. It would be different if you had a d series to start out with.

I've been searching about turbo's for my B16 and I found GO-AUTOWORKS turbo kits (GO-AUTOWORKS Civic CRX Integra Complete Turbo Kits D16 B16 B18 H22). I'm interested in the Tuner Kit (3rd one from left to right) but I'm a complete noob and have no idea what is best.... and still have a long way to go until I have my EK ready to think about turbo/swap my motor. I'd prefer Garret turbo's and people only talk good things about the Garret T3/T4 but then comes the trim's, don't know what that is...

The car will only be driven on summer when there is no snow and it still wont be daily driven but when I go for a ride I want to be fast. What do you think about the Tuner Kit?
