i just got a set of jdm ef8 knuckles for my 90 usdm si crx. from what i have read i need to cut the inner tie rod about 2cm , can someone confirm this?
also im running raxels in the car now with a b16, will i be able to use these axels, or what type of axels are needed in the ef8 knuckle swap over?
thanks

 

I am almost positive that you do not need to cut the tie rod and as for the axles you will be fine. Who gives you this information.

are you aware that the steering arm on the knuckle is different on the SiR/VT knuckles?

i cant confirm because i dont have SiR/VT knuckles, but i am aware of the difference and have heard others having issues with tie rod length.

 

I could have sworn that the SiR knuckles are the same as 90-91 Civic EX and you don't need to do any cutting. The only thing you might need is a spacer to clear the brakes, depending on what wheels you are running.

 

that is definately not true.

here, i did a search for you. follow the link

No I was unaware of that and thanks for informing me. Sorry

 

some tie rods have enough adjustment some will need cut some will need cut and threded a little more. I would get a set of ex's, but thats just me.

 

The tie rod ends are diffrent between 1.6i-16 and 1.6i-VT (European SiR). So i think they are diffrent in Si-SiR too.

 

tyson is correct, the SiR knuckles have a different location for the tie rod end attachment point (its more inboard). I have a set of these lying around and have confirmed it. you will need to trip the inner tie rod end a bit for it to work properly.

your axles should work ok though.

I'm sick and tired of all those that give information from some other source that ...they've heared about. If you didn't do it, not 100% sure, $hut up!

I have JDM SiR knuckles on my 89 Si hatch. The reason you have to shorten your outer tie rod end is that you won't be able to get your steering wheel straight. It'll be slightly off, Very slightly. You don't have to shorten them but again if you don't, your steering wheel will be afected.
Here's my write up.

I have been to that website already, I need more specific info. Which side of the inner tie rod do I cut, the part that screws into the outer tie rod? Where and how do I add threads to the tie rod? Do i need to take the inner tie rod off the car to do this? Anybody do this procedure?

 

BUMP, who else has SiR knuckles on their ride???

 

I do.

DO NOT EVER UNDER ANY CIRCUMSTANCE cut the tie-rods. EVER.

This is your damned safety people! Don't half-*** it, and order new ones. If you can't find any, you'll need to order overseas. Tough luck, but that's the way it is.

I can give you some contact info if you need a set.

-edit-
This is one of those swaps that doesn't come with bragging rights. If you can't get the parts, do the EX swap instead. It'll give you the exact same brake setup, with alot less headache. I happened to have access to parts. Made my life, and swap, alot easier.

dude cutting them is fine, i did it on my old setup no problem. If u dont the toe in is way off and u cant get to to zero toe, i cut off 1" from both sides and alined it perfectly

 

IMO it's just not safe to cut away that much of the threads.

The only way to do this safely, is to bore and thread the rods again. Wich is a huge pain, and will land you in a world of hurt, alignment wise, if you doo it a little bit crooked.

I did mine in a shop with the help of professional fabricators. We opted to simply put new parts on it instead of butchering old parts.

dude by shortening it, you dont change the integrity of the part. I used a 14mm die when i was done to clean up the threads and it worked mint. By no way butchered.

 

Thanks for the replies guys, now can someone tell me which end of the tie rod to cut?? The part that screws into the outer tie rod?? That end is 22mm so wouldnt you need a 22mm die?? Can someone post some specifics, Thanks.

P.S. I am going to have this professional done by a customizing shop, just need to know what to tell them to do.

 

take the outer tie rod off, the remaining thing is hte inner, cut that one 2cm and find a 14x (i forget the pitch ) die to clean up the thread

done

I totally agree. I have originally taken the inner tie rod ends to the machine shop and had the threads extented on the inner tie rod ends a bit so that when you shorten the outer end of the inner tie rod end, you'll be able to move the outer tie rod end more in.
You don't want to definately be in a situation where you have few treads in locked in with the lock nut, but you'll see that's not the case with this mod.
BTW, JDM 4G civic/CRX outer tie rod ends are EXACTLY as the N.American.
That's why I don't suggest you cut them right away. Check how much roughly you need to take off. Thinking about it more, I'm wondering what position of your steering are you starting off with????? This could play a big role....

It is very interesting that some using the so called SiR knuckles which are identified with LH3-N on the left one and the RH3-N on the right one have such various degree of toe problem. When I bought mine, I saw them come off the car so I'm sure they where the SiR units. Perhaps there are others with the same marking but are not the SiR ones????

 

I finally have got the inner tie rods off the car, they were actually extremely easy to remove, except for seperating the damn ball joint! I dropped them off at the machine shop today to be cut and have the thread extended. If you dont extend the thread there is know way you will be able to get your toe-in correct AND use the locking nut. Driving around with out a locking nut seems like something you would not want to do for long.

By the way my SiR knuckles were stamped with LH3-N and RH3-N, its seems everyone with these knuckles has the same toe in problem.
