Your Mods To 2006-2011 FD Civics

Im not sure whether people have posted about this before, but i remember someone telling me that the K20Z2 is the achilles heel off the K series engines.

Has anyone ever tried putting K20Z1/3/4 blocks/heads onto the K20Z2? I thought all the K20Zs were rubbish until i youtubed them and saw that some mad as hatter EGs with K20Z1 and 3s...they seem to be comparable to K20As? (wikipedia told me that the Type S uses the K20Zs and so do the Euro Rs)

If it is possible then would it not open more options for people who own FD1/2s?

Sorry if this is a noob question, i havent been able to find many people who can report they have done any engine mods to their R18A1s and K20Z2s. If you know a thread please link.

Thank you =)

^^ dont think anyone here has interchanged engine parts from other k20z engines with the k20z2.. although there is one that has had a k20z4 swapped into an fd1

in other news.. someone stole my red valve caps :( BUT they only took 2 of them lol. luckily they're not rays or anything expensive

I don't think they're quite that bad! Low power output maybe...but drives nice and smooth with a good amount of torque.

@ Aero
Was it a difficult job? worth doing in an FD? or is it nothing as simple as dropping a b16A into an EG4

@xenon
I wasnt saying it was a "bad" engine....id just like a little more..excitement? For a "sport" it just seems to drive a little too smooth

It was me who said it was the achilles, and i said it was the Z2, you must've misread me.
The Z1 Z3 and Z4 are awesome!

You could try changing bits if u were daring...

What do you guys think of this short shifter kit? Looks comparable to the skunk2 etc...

Lol nah didnt misread you, i said the Z2 was...Not keen on that idea, dropping in a Z1 seems to be more feasible...Is the general construction for Z2 the same as the Z1/3? Except for the internals of course do the drive train, flywheel all link up the same?

I guess what im trying to ask is that is it just a matter of taking a Z2 out and dropping a Z1 in

have you tried this? i emailed my mate that did this to one of my older cars to see what he thinks. i never got him to do it to my last car as i was happy with teh performance, but i always remember him making the change and my car had a definite boost in performance. even he was surprised. i wouldn't really try it myself as I don't know much.

it causes a funny idle, but don't know if the ecu in the new civics would be smart enough to adjust to the air temperature difference it causes.

not a mod.. but you know.. i couldnt help myself hahah

its not as simple as slapping a new head into a fd2, compression ratios in the blocks are all different in the k20z series

and also dropping a k20z4 into a fd1/2 is not cheap and it is quite difficult (i.e - ant no backyard job)

dont get too ambitious into making the current 8th series civic into a power house, it is more of a family orientated car unless you have the funds ready to do so, if it was cheap and easy most of us would already be rocking with 150kw+ atw
