beastgtir Posted January 25, 2015 Author Share Posted January 25, 2015 I thought we were talking about the frankenstien k24 bottom with k20 head .. Therefor the restricting factor in terms of high revving is the bottom .. Therefor, we were talking about the bottom not being able to match the natural rev ability of the top ! The K24 stock revs to 7,600 max. Pointless taking it higher as most cams drop off in power around that mark hence needing uprated valve train/cams to get it to rev higher. Plenty of americans hitting 8k all day long on stock k24 bottom ends. The K20 oil pump is used but its only good for around 8k, revving any higher most people bore it out or use the s2000 oil pump modified by earls usa to fit. So the limiting factor is Cams, head work and oil system. The bottom end is isn't that weak that it wouldn't take any high revs, its just the simple fact that theres no gains to be had from revving it high.

DAVEMB2 Posted February 1, 2015 Share Posted February 1, 2015 Mmm k24 nice yep you will need a k20 oil pump , and they can run over 8000rpm if need be ,my k26 can rev too 8200rpm and I would think a good set up you should see anywhere around 230/245bhp @beastgtir@Krzys@Grant@philgor@UnicyclingTom 3 Quote Link to comment Share on other sites More sharing options...
beastgtir Posted February 5, 2015 Author Share Posted February 5, 2015 I would be very disappointed at 230-245 BHP.

Its from the Isle of MULL. I am now at the make it or break it stage, CAMS! This is looking to be the most expensive part of the build along with k100/k-pro and mapping.Cams will need dual valve springs and retainers, with a set of Drag Cartel cams this is around £1000 without fitting. I'm looking to delay the build for a month or so to save up for a set as I know I will always be curious about what it would be like with a set of cams! With the right set of cams I would be desperately be aiming for 300 BHP N/A. Probably going to get a LSD box too, either retro fit DC5 lsd or similar. Exhaust wise, I will be going 3". May possibly get it done by Rich (dynodaze). I would be using a Skunk 2 back box with 3" inlet or a Vibrant racing backbox. Mapping to be done @ Eurospec by Romain.

Mapping to be done @ Eurospec by Romain.Are now I was saying 230/245bhp as a good standard set up you are not going standard are you hi com pistons ported RBC and so on , you will like it when done coz like me you should be able to get. Around 40 mpg and yes 300bhp is poss or close anyway I would say 270/310 bhp @beastgtir Quote Link to comment Share on other sites More sharing options...
beastgtir Posted February 6, 2015 Author Share Posted February 6, 2015 Going to get a 74mm super 90 (s90) throttle body too. £166 delivered with adaptor for RBC. This engine build is starting to get me on a power hunger !! Trying to eek out every last bit out of the engine. Building cars isn't cheap. It was meant to cost me around 3k all in originally for a bolt in stock k24 swap but since then I have spent a lot more but I've haggled a lot and got good deals on most items well below retail. All the guys selling the drag cartel cams are stuck on pricing. Not willing to nudge anything off! Might be fixed prices like hondata set for dealers.

beastgtir Posted February 6, 2015 Author Share Posted February 6, 2015 @DAVEMB2 Most likely I will just keep the 30th anniversary as an occasional car. My mb is my daily! Quote Link to comment Share on other sites More sharing options...
DAVEMB2 Posted February 6, 2015 Share Posted February 6, 2015 O the cost just goes up i know the good thing you have is that it fits and have no probs with the rest of the bits coz it's going in the ep I had to custom build and rejig to fit it into an MB2 and had to do brakes and every other bit on the M had to be rebuilt Quote Link to comment Share on other sites More sharing options...
beastgtir Posted February 8, 2015 Author Share Posted February 8, 2015 Yeah I didn't want the hassle of mounts, shifter box and so fourth as that's around £2k in bits alone so went for an EP3 shell. Also as you said, with an older shell everything else needs doing too.. Good news is that my 30th anniversary civic has arrived. Got this very cheap as the engine has blown. Sadly the rocker has been off and head is ruined (rusted cams etc) but a friend has a pre face lift head for me. Was from the Isle of mull so quite a trek!!

beastgtir Posted February 8, 2015 Author Share Posted February 8, 2015 Now I'm just awaiting to do a deal on cams, backbox, dual valve springs and titanium retainers plus a few little bits then I'm good to start building the engine. In total it will cost me around £5k fully finish. For an all motor k24 30th anniversary I think it's a good price!! Quote Link to comment Share on other sites More sharing options...
