THE ULTIMATE K20 / K24 ENGINE BUILD GUIDE

what's going to Mike here again the ultimate K 20 K 24 engine building guide video I've been asked by a lot of people to basically compile a video that's going to be a central database of information regarding this engine build an engine swap a lot of information is kind of scattered out throughout the internet but I wanted it to compile it to one video that could help anyone wanting to build this engine and not only that I wanted it to be a place where pretty much a database where people can comment in the section down below with tips and tricks and their own input regarding the K 20 K 24 if this video becomes outdated you can actually input you know newer information in the comments section so to help anyone in the future so this is something that I wanted to put out there that's very important just to help a lot of people out there that's trying to perform this engine swap so we're gonna start now with cylinder heads our guys we're gonna talk about cylinder heads right now we're gonna talk about the commonly used K 20 + k 24 heads which are centrally VTEC heads and some non-vtec but we'll get to that later I want to talk to you about the commonly used ones the first one up is the our BB head this one is used from a 2004 to 2008 TSX this is the lowest flowing VTEC head at 279 CFM this cylinder head is found in the engine code k24 a to the next head we're going to talk about is the RBC head which comes from the 2006 to 2011 Civic Si this head flows at 291 CFM and the next head we're going to talk about is the PPA / and/or the ppl cylinder head now this cylinder head is found in the honda crv but this cylinder head does not have VTEC if you guys are wondering but it flows at 297 CFM and it flows you know actually higher than the RBC which is a K 20 head but this this cylinder head does not have VTEC so this comm this head is used in a VTEC killer setup which basically locks a VTEC cam to its highest lobe this is this this cylinder head is probably the cheapest high the best bang for the buck as well so be on the lookout for those cylinder heads the next cylinder head that I'm going to talk about is the PRB cylinder head which flows at 299 CFM now this one is found in the RSX type s from 2002 to 2006 this head is the highest flowing head that you can get in the US on certain stock cars but there is a step above which is the RSP head the RSP head comes from the Civic type-r in Japan and is very rare in the United States but it comes with a factory port job and it flows at 312 CFM so with that knowledge guys choose your head wisely I'd say that if you are going to perform a turbo build you know any any one of these heads are gonna you know suffice but if you're gonna go all motor you'd want to pick a head with the higher CFM to get the most power out of them unless you're gonna get imported which you kind of once you get them ported they're kind of all that I don't I don't want to call them all the same but you know with the hit with the hand port or a CNC port they're gonna all be within a certain CFM range all right guys we're gonna get into engine blocks right now we're gonna get to talk about all the k24 engine blocks that you could possibly use for this motor motor build but I'm also going to talk about ones that you don't want to use and the problems are gonna have with them versus the ones that you're going to have the best results with okay now the probably the best engine block that you can get from factory is the K 24 a 2 which is the TSX engine the TSX engine has the strongest factory rods out of all K 24 engines I would suggest anyone wanting to do a K series swap if you want the best and cheapest bang for the buck just throw a TSX engine in it and then you're golden they they have the strongest factory rods they have - and horsepower from factory and they're fairly cheap you can get around eight to nine hundred dollars now that's probably the best short block that you can just slap on a stock k 20 head on and have a lot of fun with okay the next engine that I want to talk about is the K 24 a1 Honda cr-v 2002 to 2006 now this engine is my preferred engine to use if you're just getting like a bare block and you have to buy the pistons and rods etc etc it's it's almost you can probably find them for half the cost you can for acura tsx and the blocks as well go for way cheaper than a TSX block the best thing about this engine block and this is the reason why I utilize it in my build is that for those of you who usually are going to do this swap one thing that everyone tells you to do is swap out the oil pump the oil pump from all the k24 engines if you want to rev higher you swap in a Type S k20 oil pump and the k24 oil pumps they're run by balance shafts and they rob you of horsepower they're a lot heavier they're like they're not more expensive and they're a lot more complicated so everyone gets a Type S oil pump okay now when you decide to install this type s oil pump for every other K 24 block you actually have to cut the K 20 oil pump in order to fit the block and you have to notch the oil pump in order for it to fit the only block you do not have to do that with is the K 24 a 1c RV block and as you as you can see right here in the video this is the block that I have and it fits perfectly fine and there's no need to cut open the oil pump or whatever like that and that's kind of one of its perks other than that the K 24 a 4 which is a Honda Element Honda Accord engine from oh three two oh six if you use this engine block if you have it in short block form with its stock rods and stop Pistons the Pistons will hit the K 20 head so you have to swap out the pistons in order to use that short block right the K 24 a eight which is from the oh six to eight hundred Cortana elements same problem the Pistons will hit the cylinder head and then the K 24 z1 engine which is from the oh seven oh nine Honda CRV this has a problem with the oil filter you have to relocate the oil filter because it will interfere with the intermediate shaft aka your axles so there's this big headache we have to relocate it block off this the oil ports on it so it is more complicated to use but if you get these at these blocks the ones that I don't prefer at a very affordable price it might be worth it to you know add a you know it might be worth it to you you mean and if you're gonna change the pistons anyway it doesn't really matter right so though the complications for those cylinder blocks alright guys just because we're mentioning the oil pump I have included every OM part number for the type s k20a to I'll pump this whole kit you can search for any you know going on your Honda dealership and give them these part numbers they should be able to get you the right parts that you need or you can order them online and it comes with everything you're going to need in order to install a k20 oil pump now if you guys intend to rev up to 9,000 rpm I suggest getting this if you do not you're probably gonna keep it under I'd say 8,000 you will not need to install this k20 oil pump so including that I'm going to also tell you that when you do a K 20 K 24 build you need to plug this oil jet that's in the block and this oil jet needs to be blocked for adequate oil pressure so you don't do this there could be problems with oiling of your your engine and/or VTEC I don't know so you can do this as well so while you're in there but this is a the blocking this all jet is needed to be done now we're going to talk about part interchangeability some of the parts from the K xx and K 24 are the same and some are not so we're gonna go through it to make sure that you have every part that you're going to need in order to do this swap so the parts that are are interchangeable by the crank pulley some of them have our different diameter but they all fit the same water pump now with K 20 water pumps and I believe with the K 24 water pump housing they're different because some of them have an oil cooler but you're going to have this little water neck for an oil cooler so be aware that oil pan the oil pans are the same some are made out of steel some are thicker and a loop made out of aluminum depending on what Pam pan you need to use I believe with the K 20 oil pan you're going to need longer oil pan bolts like they're the steel ones they're a lot shorter so if you go with aluminum one you're going to need longer ten millimeter bolts head bolts head studs they're both the same and you can reuse ones we would recommend using a new ones because all in one stretch but I've reused head bolt head studs in the past and if it wasn't boost if it wasn't if the motor wasn't boosted I'd never had a problem so parts that are not interchangeable timing chain the K 20 chain is too short because of deck height so you're gonna need to get a K 24 I'm going to include the part number on the thing below timing chain cover again the K 20 cases are too short dipstick the K 20 dipstick is too short and K 20 head gasket you have to use the K 24 head gasket because the cylinder walls the bore of it is a seven millimeter and the K 20 is 86 millimeter so you have to use a K 24 head gasket that pretty much covers the engine build itself but I'm going to talk about miscellaneous things that you guys might have questions on regarding a case wat one thing I want to talk about is intake manifolds now there is two styles of K series head design as far as intake manifolds are concerned if you want the best bang for the buck intake manifold it is the 2006 to 2011 civic SI RBC intake manifold with this intake manifold you can probably give them online I'm going to put another part number on it as well there are only 200 the higher $200 range best flow best bang for the buck other intake manifolds don't really compare price-wise around that price range like Honda knocked it out the park like it's like 200 bucks and you get like one of the best flowing K series intake manifolds great for high revving it's gonna suffer low-end but anyway let me talk about one of the problems that people have so depending like like the original K 20 head like a PR behead the the water neck is separate from the intake manifold I'm gonna show a picture to explain that whereas when you go to the newer Civic Si 2006-2011 they integrate the water neck into the intake manifold so what a lot of people do is they cut off the water net part on the RB C intake manifold and then they they adapt it into the K 20 head the bolt pattern is the same it's just the water next section is is different so that's kind of something that people do all the time and so you're gonna see a modify pre modified or modify our BC intake manifolds so it's easy to do yourself if you just have a grinder and like a like a saw or something like that it's it's pretty easy to do if you want the best flowing om intake manifold it is the RC intake manifold and this is like a Type R intake manifold and it's pretty rare to get I've seen some on the market and they they range like around like 600 bucks like from Japan or something like that like six like six to eight hundred or something depending on it but for that price range if you want a better intake manifold there's no question the scum to ultra and ultra race manifolds the design on those things you know they give you a lot of horsepower that's the one that I'm running and if you want a the best intake manifold that you can get you want a center feed intake manifold there's a lot of them floating around it's going to makes one I think forgot forgot the name of the other one like it has an ex ex like excessive excessive and then I think pre Anto has a one but anyway those are the types of intake manifolds that are out there you can want the most horsepower the center feed the center feed is just kind of awkward because now the placement of the throttle body is is you know in the center it kind of throws everything off so you have to be custom with that but it does provide the best power because it provides equal flow to each of the cylinders now as long as we're getting into the intake manifold just I want to talk a little bit about the throttle bodies in the k-series engines some of them have manual cable driven throttle bodies and that's a majority of all the swap cars the older cars I pre 2005 civics people who have mr2s they all want those types of throttle bodies that are manual and then there are drive by drive by wire throttle bodies which are like electronically controlled so the newer gen engines I believe past oh six are all drive by wire so people convert all the throttle bodies to manual cable driven throttle bodies yeah so there's driver wire drive by cable so those are the issues that you're gonna have if you have a newer newer newer car that is you know has an electronic pedal you're gonna need you know drive by wire and then if you have a older one you want to drive by cable so that's kind of the lowdown on intake manifolds as far as headers there's many hitters out there as far as I'm concerned the bigger the better you want a minimum three inch exhaust on your K series motor if you decide to run it exhaust and you want really big primaries on your header you know big tubes on the header get you know all the exhaust out of there as quick as possible you're gonna make the most horsepower but I don't know I think that's it I think that's it as far as K series are concerned if you have any questions please comment down below leave a message or leave a comment I'll try to answer every single message I can and if I don't I'm sure somebody will chime in and you know we'll try to make sure we correct each other on correct you know the correct answers for everything so don't get alarmed and I know some of my people are going to make sure that everyone gives the right information when it comes to this so that we everyone can have really fast K series and and yeah send it anyway thank you guys please like please subscribe until next video take care peace
