oh really?? as a rough guide, how much cheaper would it be? also, if u change the block, would u need to re-register it? (or whatever its called) because of the differing engine numbers? taking that into consideration, would it still be less than a bore?

lastly, i kno rod to stroke ratios have been discussed to death, but only changing the bore will keep the rod/stroke ratio the same yes?

sorry if some of these are noob-ish questions...

oh, one other thing. would a bore and sleeved b18c be more reliable as opposed to a b20vtec?

If u have an integra, upgrading to b20vtec requires only a blue slip to change the engine number. No Engineer Certifcate is required

Right , because it is under 15% capacity range
from standard engine. This means , the standard brakes are
designed to cope with the theoretical power increase / loading.

if you ignore the emmissions test/ADR's etc...

Doesn't it come under the same rules as "replacement engine " ?

That is , using all emissions standards
from the chassis year ( ie obd1,obd2a and obd2b) etc ?

Easy on a b series to make it relevant to it's chassis emissions standards

LOL, only if you don't change anything else.

so you need to keep factory B18 ECU, B18 Honda fuel pressure, B18 Honda air intake, B18 Honda header, B18 Honda exhasut etc etc etc...

Good points , of which none would be relevant to anyone putting this engine into said dc2 or dc4 !

Eh? This is getting abit confusing. If we all "comply" to ADR/emissions, every single honda will be off the road except for the brand new cars. So I don't know why that was even mentioned, you shit stirrer tinkerbell! :p

If you put a 2.0L engine in a car with a 1.8L engine, there is NO need for an engineering certificate, just get a blueslip for a change of engine number, if the RTA hassle you, call superwog. If it has to do with dates of manufacture, then you're looking at EPA emission constraints.

It's not that a hone is cheaper than changing the engine number, it's the cost of buying sleeves, having someone put them in for you alongside the risk of having a dope install them incorrectly compared to an odd $500 b20 engine from the wreckers with good supporting mods that will be very rewarding.

If you have a budget to sleeve a b18, you have enough of a budget to build a pimpin' b20vtec.

B series engines are nearing on 15years old now so they are starting to get a little tired. It would be ideal to build that engine with some goodies here and there while you freshen it up for better power/reliablity also.

K-series is not expensive as most people would think it is. If you shop around, you can find a K20 running gear for a decent price (sometimes if your lucky a price of a B18c Type R conversion). Same deal with the B-series, you'll get yourself a tunable ECU, headers, exhaust sytem and Intake system. This is ALL required with the K-series as well. The extra money is needed to go into the Kswap engine mounts and the conversion harness. If your really tight on a budget, OBX make Kswap mounts and you can make your own conversion harness (there are a few DIY manual on the k20a.org). So how can a Kswap be more expensive real quick?

Remember guys, B-series is getting old. Not only is the engine old, what about the gearbox, driveshafts, dizzy, starter motor and etc?

Something to think about guys

^^ So true,the b is getting on now.

^ what about shifter box and kswap driveshafts, ....

stop talking about K vs B

there are other threads fo that.
