Would you go K20 instead of JRSC B18C?

Seeing as you have seen Kev's old B16B JRSC go, would you still say the K20 would be the better option?

100%.

I posted about K20's so much on this forum haha. I just cant see how anyone can argue with it presented like this:

Fully built B18C/B20 = ~£4-5000
K20A2 Swap = ~£7000(thats with some good bits aswell)
Selling B16B/B18C =£1500-2000

So basically not even that much more expensive, plus you blow up a fully built bseries its a 3-4 grand repair bill, blow up your stock K20 and your talking about 1000 pounds.

JRSC B18C IMO would make about 240-250 with 160ish lbs ft but has high intake temps and still requires a better gearbox aswell IMO.

HOWEVER

Since you already have both the B18C and the JRSC I would go that way man, its gonna make a small amount less power, but will be different and it sounds crazy.

B18C JRSC with 4.7 FD would be super fast.

689r - i can see where your coming from with the figures laid out like that

And there is no doubt k will always be better than b

But its just the fact of having that £7000 to buy all the bits at the same time as keeping your car on the road to get to and from work, thats my situation anyways.

Ive got a couple of friends woth k swaps but havent had the chance to drive one yet but cant even imagine how good it is

For me though im gonna stay high comp b18c

And kieran JRSC b18c sounds immense :)

I may being a tad naive here with not having looked into it THAT much but....

Surely a k swap can be done for less than 7k?

When I put my rb25 in my 180sx I was told I wouldn't do it for less than five grand. Now I was slightly lucky in the fact I got a doner car, with bits on it, cheap. With selling the sr20 etc I did the swap for around 2k. And that was spending more than I needed to by a quite a way. I could have broken even.

Surely it can be done for 4k tops if you know what your doing. Take out the money you make back on your general b series stuff and youve gotta be talking 1-2.5k depending on your spec?

I was not including a price for labour.

I am however assuming that proper fitting, tried and tested parts will be bought. Aswell as KPRO, an RBC/RRC Inlet and some other things.

You could probably do the swap for less with **** parts but then it would be like 200bhp and youd have been aswell doing a B18C swap.

Cheap KSwaps are crap.

EDIT: If you had added up the parts StevenEK9 was selling when he was going to break his full car, his second hand KSwap parts (which he had priced fairly IMO) added up to around £8150.

Lets not forget your talking £1500-2000 for the engine and gearbox.

So after that you need

Mounts
Exhaust Mani
Driveshafts
Wiring Harness
FPR
Fuelling system in general
Intake
Shifter - either DC5 and cables or Hybrid Racing/Ktuned Bolt in
ECU
Radiator
etcetcetc

then extras like final drives, gearsets, bolt ons etc etc.

Its not cheap.

DOUBLE EDIT:

But its just the fact of having that £7000 to buy all the bits at the same time as keeping your car on the road to get to and from work, thats my situation anyways.

You should just keep your car on the road and buy a Kswap part every few months of whatever. Sure it might take a year or whatever but K20 EK9 really is end game.

as matthew says it's not cheap!

including a full gearbox build mine cost in the region of 8500 and that was with zero labour, that did include ALL new bushes and balljoints in the dc2 subframe and rack + all the best parts you can buyy off the shelf

All depends how far you go with the K20. i.e what manifolds you use, quality of parts you use, weather you want to rebuild it with cams or not and how much of the work you do yourself.

Think a reasonably well done swap unopend with decent bolt on's done by yourself would be around the £5-6k mark then minus what you selll your B series parts for if you sell them (Or be a horder like me and keep everything I get my hands on just incase I change my mind haha)

A standard swap with budget parts on std ECU could be done for £3-4k maybe less, then minus sold B series stuff. But I dont see the point in doing half a job.

Personaly if I was doing it, it would have to be the full job. Higher comp, cam'd K20 or go for the K24/20 and make it really worth it Ultimate N/A.

At the end of the day a Kswap in any older gen honda will add a good chunk onto its market value. Where as you can make a B series with almost any spec and It still won't fetch as much. But cost you just as much as a K swap in the process.

Im stuck as I really want a Supercharged B18C which will be prity darn fast, cool as fooook and alot rarer than a K swap. But im constantly picking holes in it and want everything to be as efficient as posible for track and the road. Plus N/A is just so much more saticfying.

Just out of interest has anyone bought a doner k20 vehicle I.E. ep3?

I'd be interested to know what they return back minus what you need for a kswap.

Edit - my next engine work will be to provide the world with a good & reasonably priced k-swap!:D

With regard to those who know more than I do... Witnessed/done kswap.

What would you consider to be a reasonable price for a k-swap? Doesn't have to be all singing and dancing.

Gimme a ball park from figures:

I.E. 200bhp - 4k minus original b series parts

I like a challenge, I'd be interested to see if it can be done. Ignore the hp figures as a rule as I'm not interested in chasing numbers but obviously certain parts are going to help to obtain a certain level of output.

In fact not just the experienced, what do the novices think in terms of budget?

If your not intrested in chasing numbers then just go B18C dude.

A well done better B18C swap is better than a half assed standard ECU K20 swap man.

EDIT: Iv now reread your post several times and to me, what it basically reads it 'how cheap can i possibly do a kswap?' this is not the attitude to have. Kswap requires large amount of cash. Trying to do it cheaper and with sub par parts will only end up in you replacing them and spending more than the original higher cost would have been. 'buy cheap buy twice'


Basically, if you have to ask, you cant afford it.

A standard swap with budget parts on std ECU could be done for £3-4k maybe less, then minus sold B series stuff. But I dont see the point in doing half a job.

Personaly if I was doing it, it would have to be the full job. Higher comp, cam'd K20 or go for the K24/20 and make it really worth it Ultimate N/A.
This is pretty much how I see it too, however,

At the end of the day a Kswap in any older gen honda will add a good chunk onto its market value. Where as you can make a B series with almost any spec and It still won't fetch as much. But cost you just as much as a K swap in the process.
This I do not agree with, to reference some recent examples Stevie9er, Danf from civiclife, DrMikeys old cars and most other Kswap cars have either been sold in parts or for a much lower price than Im sure the owner wanted to sell it for.

Sivti sold his k20a Ek whole recently for good money I believe actually

This is the thing, I'm not. However the appeal of how a k20 drives work for me. Plus if I did want to go chasing numbers at some point in the future beyond a k-swap them the option is there. With a b-series you'd be chucking money at it for what? A good well round useable b-series at the most is say 240 for arguments sake (talking n/a here) and thats Gunna cost you a few quid. Probably as much as a kswap. So for the potential aspect alone I think it's worth it over building a bseries.

If I'm right in my logic a k20 provides more useable power?

Definately k series has more scope for improvements and more useable power(torque really) lower in rev range, think 9er was about 25bhp up,and 6 speed box delivers it well. Really I think anyone that goes out in a good k car is sold then haha.

i bought a k20 donor car and sold on most my old B series stuff

i had to buy
new mounts + shafts as i didnt want to run EKK1 ~ £600
header ~£300
3" exhaust £450
rbc+ adapter + intake ~£380
tune at tdi £350
dc2 rack + subframe etc ~£150

so thats all plus what i paid for donor car

i think the swap alone stands me at around £2000 after everything i sold

hard to calculate exactly how much as i done lots of stuff at same time, spoon calipers double din conversion, repainted bay, new rear discs + caliper refurb...

it didnt cost me ALLL that much in the end tbh..... i could ask my mate how much he spent as he bought everything new and didnt use a donor car....
spent alot more than me ahah

I am a big B series fan, can't get enough of the rawness and VTEC is soo much more aggressive than the K series, but the K has more torque and responds much better to bolt ons, I have driven EP3's and I felt a mild disappointment, its too quiet and refined for my liking, it doesn't scream like my B16 does, and can I justify paying for the K20 conversion costs...NEVER!!

But K's are coming down in price slowly so it be more common as the years come, but my love is with B series no matter what anyone says.

Driving a K car ( dc5,ep3,etc ) aint nothing compare to driving a K-swap car...
