hey guys. had a couple (alot) of questions on EK9 seam welding. i have never seen an authentic EK9 ( i live in California ), so i was wondering how much of the unibody was seam welded? did they (Honda) do spot welds a centimeter apart, or are the welds continuous? what parts of the engine compartment received this treatment? can anyone post a couple of pics of the seam welding? Thank you so much in advance.
 
The welds certainly aren't continuous, continuous welds on car bodies would warp the shell.
 
A lad on Civic Life seam welded his EG shell, he did an inch of weld, followed by an inch gap and so on... as Champ White said, If you ran a continuous bead of weld you'd warp the shell :)

being a welder myself, i understand that a continuous weld would warp sheet metal. i was referring to making re-passes to eventually have a continuous weld.
 
from memory when i had my car stripped to cavity wax it the only area to have any additional welds was under the back seat area,

the welds were only stitches here and there, nothing fancy.

in the past i have used the weld an inch leave an inch method on engine bays and around rear suspension mounting points. this method is quite comonly used on competion cars and is more than enough,

thats what i was thinking. like i said in O.P., i have never seen a real EK9, so i just wanted to make sure. i have already started my seam welding, and i wanted to make sure im not leaving anything out on the engine bay side as im am about to drop in my baby-R built by Mike LASKEY.:))
 
the bits i would concentrate on on a ek would probably be:

strut turrets to chassis leg area
chassis leg to front lower crossmember
chassis leg to bulkhead/floor.

welding on brackets for a strut brace is also worth while.

is it going to be used for competion?

well..... i would say yes. i want to run it at WillowSprings. i think i have already did an "overkill" on the welding. lol! ill post some pics when its rolling again. also thank you.
 
i just an opportunity to take a good look in an ek9's engine bay. I could see the differences in the seam welding straight away. Basically, where the panels are joined to each other in a manner "similar" to rivets ( o o o ) in my ek4, the ek9 instead has a continuous seam welding about an inch thick resembling ( |||||||||||| ). This is so throughout the engine bay. We all know they are many other improvements as well, but this is one that stands out.

are you refering to the sealant they put on top of the weld's? has a very similar appearance.
 
when i said an inch i wasnt referring to the height. I meant the width. It's kinda difficult to explain anyhow. To be honest, it could have been sealant ( maybe that would add rigidity ) but i am certain that it is not there in my car (ek4). I would take a pictures of both engine bays for comparison. I am sure that everyone would see the diferences there.
 
wouldnt worry about whats done on the ek9, just get company who preps cars to high standard to do whole chassis for you and youll end up with better shell than a 9 (lot of labour and cost but quick glance through thread shows your not cutting corners)

theyll know what areas need doing etc, also remember some areas of ek9 shell are thicker and no sunroof
 
ive done the engine bay of mine, some difference it makes to the thin metal pannels around the headlight area, they have went solid now, will see what difference it makes when i get the car back on the road

What? Haven't seen a real EK9 and you live in So Cal? Go to a Honda-Tech meet.

Anyway, check out L•Con - 05.21.10 for chassis prep.
