DIY S13/S14 on your Y33 conversion

First you need to get the parts

Either obtain ALL s13 or ALL s14 makes life easy1. LCA2. Knuckle3.5lug front hub4. Coil over5. Aftermarket S13/14/15/z32 are all the same and fit outer tie rods (ill explain why later)6. Aftermarket tension rods (might as well right?) S14 work on this instance, I’m sure 13 would as well since they are adjustable. S14 is longer than 137. Y33 top hatsALL BOLT SIZES ARE FROM MY HEAD, IE MIGHT NOT BE ACCURATE

Ok, the ONLY downside is the sway barI disconnected mine because I didn’t have timeBut what ill end up doing is drill a hole through it, and using an s13 sway bar mount bolted directly to it. It won’t be at the exact same mounting points, but I will work.

OkokokokokI’ll get to the actual conversion1. Remove your brakes from the knuckles, and put them aside somewhere (zip tie helps to hold it up).2. Remove the sway bar vertical bracket, its an internally wrenching bolt, so you need to hold it with an Allen head, then use a 14mm wrench to remove the nut, slide the brace out, and do the same for the bottom, but it’s a 17mm I believe.3. Remove the tension rod bolts to the LCA. Bottom are 14mm, top are Allen (on my application I had tension rods already)4. Loosen the LCA bolt to the sub frame, 19mm on both sides. Take the nut off, leave the bolt to support it.5. Take off the upper suspension top hat nuts, and let it drop. Be sure to hold it so it doesn’t smack you in the nuts like it did me the first time.6. Smack out that LCA bolt and BAM its out. Throw it to the side.7. Put the Y33 top hats on your new coilovers.

OK for installation you need to pay attention to a few things.1. Make sure your new coilovers have appropriate springs. When I order my new coilovers soon I’m going with a 12/10 so when I put airbags on it, it will be valved correctly for the stiffness I want. Everyone will be different. 2. Install the hub on the knuckle, and the new tie rod ends onto the tie rod. 3. READ THIS PART******************************If YOU DO NOT HAVE THE AFTERMARKET TIE ROD ENDS YOU WILL HAVE TO BORE OUT THE BUSHING THAT THE TIEROD SHOULD GO INTO. I DON’T HAVE A MEASUREMENT, I COMPLETELY FORGOT TO WRITE IT DOWN, BUT JUST DREMEL, AND TEST FIT…OVER AND OVER.4. install from reverse5. I recommend LCA first, then tension rod, then tie rod end, and then install the shock to the body, then the knuckle to the shock.6. Install your old brake rotor, and caliper, and put on your wheel after you double check and make sure everything is tightened.

Now would be a good time to do a brake upgrade if you want to. I put on GTR calipers with R33 brake rotors. Bolts directly up using the lines that came on the brakes on the gtr.

Other than that, it’s fairly straightforward. If you’re not doing hella aggressive driving don’t even worry about the Sway bar in the front. Only reason I am is because I want to track my car next year, so I need it. Also, if you don’t get ABS hubs, you won’t have it. I got NON ABS hubs, because I HATE abs. I don’t like electronics getting in my way of the feel of the road.

Regardless ill go with a few meters

DIFFICULTY-7 mainly because of the common sense needed that a lot of people don’t have. You may have to source hardware if you don’t have it for things like the coilovers mounting on the knuckle. Also if you change your brakes you have to know how to bleed them etc etc. TIME- It shouldn’t take you more than 4 hours from start to s*** took me 3, and I changed my brakes, bled the entire system, put trust brake fluid in and rebled the whole system, and then installed everything, forgot to change out the springs, dropped the strut to change springs, then the tie rod end didn’t fit so I had to bore it out etc ect.So even if your dumb it shouldn’t take more than 4 hours.

Now get out there and do it!

I guess I am missing the point. Why would one install a suspension from a car weighing 800 to 1,000 pounds less on on that end?

To go lower or to open up after market suspension options. Though the "source car" weighs less, there are some serious "race ready" durable components out there for those pieces.

The idea would be to get high quality replacement parts, much like some G50 guys are using stronger after market Z32 RUCA's, Tension Rods, etc.

How much lower might someone be able to go by doing this conversion if they are doing air?

because you didnt do your researchJIC FLAT spring rates are guess waht.

8.690% of coilover ooptions for S chassis are what?

8.6no change

as low as you want, i can adjust my coilover right now and sit on teh ground if i wanted to.

Do the s13/s14 suspensions sit further back from the wheel? I need to mount up one of my old works with a big spacer to see how much room i have with the y33 suspension.

s13 is hte same widths14 is 5mm wider

good work yokota... I would assume it wouldnt be a real big deal to get custom sway bars made for the car.

How far off are the S13/S14 coils to the Y33 stuff?

if yuo have fully adjustable, your fine

rears I say s14, an aussie friend that helped me pioneer this (kinda some JP guys haev done it, but neither of us saw one in person), he says s13

either should be fine in all honesty

Im just playing devils advocate so dont take this the wrong way, but if you wanted to put some S chassis coilovers on your Y33, why would you want to replace all that other crap with the S chassis stuff if the coils already bolt up?

?

im lost....explain more your quetsion please, and ill explain

my question is why would one put S13 or S14 suspension parts on a Q if the S13 or S14 coilovers already fit?

dude, they dont

its a completely different arm and knuckle setup

ok.... Now i understand apparently I didnt get that from your OP. Thanks!

so the point is to swap all these parts on so you can run aftermarket stuff from a 240 on a Y33. Sorry for being so dense.

hahathats why i was like WTF im lost lol

Yeah, I guess "to open up after market suspension options" didn't make sense .

Sure would be nice to find some info like this for the G50 (hint, hint)

To clarify, we're talking Y33, not (FG)Y33, right?

like 96+ Q45

whatever this body style is in the US

if i had one laying around id do the RnD for you, but i dont even know if there are g50s in japan...never looked to gfind out.

So ive gotten myself in a quandary. I have a 98 Q45 . I bought S14 ABS front knuckles, aftermarket adjustable control arms , and coilovers . My issue is i don't have the S14 caliper brackets so i dont know if my Q45 calipers, hubs and rotors will play nice on the S14 knuckle and caliper bracket . Also, does the tie rod end from a 240 fit the inner from the Q45 ? As for the rear, I just bolted in the 240 coilover but seems a bushing/spacer might be in order for the lower eye mount . In addition if there is a difference in rear strut from S13 or S14 in lengths it would benefit the Q45 to have the shorter one. I have S14 coilovers and with the length adjusted to shortest and spring preload to none but not loose my Q45 sat higher than stock . Right now it's only a half inch lower and thats with almost two inches of slack between the spring and top mount at full extension . ???

Where can i find these aftermarket tie rod ends ?

Hope this time bit helps someone from committing suicide . S13 and s14 coilovers have totally different tops . The bolt spread is smaller . I don't know what you mean by Y33 . I have a 98 Q45 s14 fits s13 does not ! You are a useless resource of misinformation . Oh and s14 outer tie rods thread right on the 97-01 Q45 so an aftermarket tie rod end isn't necessary. I've got the entire Y33 to S14 swap figured out . Anybody care to know more ?

Y33 what year ? 97-01 S13 won't work .don't see how both could work when they have different tops .

Thank you man can't find y33 fronts or rebuild

Hey he's clearly states to use y33 top hats you donut

S13 stuff doesn't fit

I know im latie for this but Are you saying that the s14 top hats that come with the coilovers fit on the q45 cause I just made some I guess I got the s13 ones

You cant use s13 tophats. you will have to swap them out. the bolt pattern is off iirc

Correct. Y33 tophats are Y32/y33 Model specific, and side specific.

Also, fun fact. You can use 03 Maxima sway bar endlinks if you're doing it on a y32, by drilling a hole in the side of the lower control arm at the appropriate spot. The Y33 sway bar is different.
