I know some people have put a s14 subframe in a s13. I was wondering if it is worth it and how do you like it. Also what control arms and all sis you use.

Thanks,
Jason

worth it.

easy swap, you use s14 suspension/s14 diff cover now in the rear

What's the advantage of doing this though?

You can use all of your s13 suspension.

The ONLY things you need are s13>s14 Conversion bushings, which SPL, and I beileve Stance sell.

And s14 rear diff cover.

s13 Subframes have a lot of anti squat built into them.

s14 Subframe = more grip

I will def have to do it then. I appreciate the info.

Another question I have is do I use a s13 rear sway bar or do I use a s14.

booey13

S14 sway bar because it's wider than the s13

I take it that it will mount up with no issues

anotheraznguy

also, the toe arms width is different. so if you have s13 vs s14 you need to change toe arms/

e1_griego

^No, the arms are the same, the conical spacers are different. The s14 has a wider mounting point.

And the rlca mounting points are wider on the s14 subframe, so if you use s13 rlca's then you need to use washers or something to take up the extra space.

i know it 7 months old but no need to start a new thread , i just pick up s14 subframe and diff cover , going into s13 , i know i need conversion bushings and im going to get all new arms my guess is it would be easier to get s14 arms , but what about when i get coilovers will s13 rear coils fit or would i need the spacers like they use on s14 front knuckles, or would solid bushing in s13 frame be the same as swapping in s14

Pinggg

s13 rear coils will fit on s14 sub frame on a s13, i have the conversion done on my car.

Book marking that link above, great info

thanks
how do u like it ? do u ever go to towers would be easier to talk in person

and yeah i went throw that link good stuff there

Pinggg

yeah i use too until i took my car off the road for a build like 5 months ago.. i usually ride out there with my buddy from up north then go drifting and racing at us27 for the night haha.

Those damn offset bushings are not required to do this swap. Figured I would note that since I keep seeing people insist on using them. The stock rubber bushings will give enough side to side for you to mount the SF up to the car. Your biggest issue with the swap will be exhaust hangers. The only arm you may need to swap is the RLCA, although I just used washers on each side of the bushing until I cleaned up my dookie set of S14 RLCA's.

Also, the only factory suspension I have in the rear is the RLCA so if anything else OEM doesn't fit then I really wouldn't know about it. Haha

Good luck. I'm happy with the swap. Glad I took the time to rape the doner car down the road for it's subframe.

my bushing are no good and i want solid ones ,i was going ti get all adjustable arms for s14 , thanks on the heads up for exhaust hanger

This sounds like a BAD idea, there's no way those bushings will last if you're putting a preload on them.

So, to do this swap i need:

1. s14 subframe.
2. s13>s14 Conversion bushings from spl or stance.
3. s14 RLCAs
4. would other s13 suspension parts will work? what coilovers s13 or s14? is there any other parts i need?

bunch of stupid idiots in this thread


yes, you need the fucking offset bushings. i dont know how fuck-face above even suggested stretching the fuck out of the OE bushing to slip it onto the subframe. thats like shoving a fist in a womans vagina and leaving it there, 24-7.


you will need...................................
offset bushings (with shims)
lower control arms
long control (toe?) arm (which has proper width, none of that spacer nonsense)
spindles
diff cover

remember that you will need bushings for practically everything since its all old and shot. this means control arms, spindles, and diff bushings.

also, dont waste time burning bushings like _every_fucking_idiot_ suggests, as its a complete waste of time (unless you like blowing black bogies out your nose). drill the majority of rubber out of the bushing and use a recip-saw cutting inwards towards the subframe (as opposed to the thin outer areas).

i also suggest avoiding poly urethane nonsense, unless you want to spend a lifetime under your car removing the bushings, re-greasing them, and re-installing them. i have yet to see ANYONE make a clean setup w/ grease fittings, its all sloppy joe ghetto style.

so bushing alternatives are to get nismo (if you can find them) or get raped financially buying spherical bearings which are harsh and not really ideal for a street car, plus they are not designed to last tens of thousands of miles.

remember, people on this forum are STUPID. use your common sense.

Thanks for clarifying

^ listen to him and do it right the first time.

In my years of being outside my cave I found that common sense isn't so common.

so i need s14 spindles too? starting to see im in more then i want but oh well

e1_griego

Not to argue, but the toe arms are the same length, it's just the mounting area that's a different width. I wasn't saying to run a spacer, just recommending finding the RIGHT conical spacer (SPL use to include both sets with their toe arms).

s13 toe arm in s14 subframe:


Also, most of the people stretching out the bushings to fit are trying to conform to Street Mod autox rules which explicitly prohibit offset bushings. It's not the right way to do it, but that's usually the impetus.


The taper is different between rear s13 and s14 ball joints, so you will need to get s14 spindles or take the opportunity to run z32 aluminum uprights (but those will necessitate changing your lower shock mount to z32 fork style). The length between s13 and s14 rlcas is the same, it's just the bushing width that is different. The RLCA inner bushings are 40 mm wide on S13/Z32, 50mm on S14s.

you could just find someone to mod your subframe to take out the lca tilt in the s13 subframe. Powered by max did it on a customers car but i can't seem to find the article now.

ixfxi

I tip my hat off to you sir. Not even going to argue because you are indeed correct. My post was just saying "stock for stock." For an OEM bushing to work properly, it needs to be torqued onto the vehicle when laden. Adding washers and doing bullshit like that obviously negates the point of doing all this work, besides being ghetto.

e1_griego

For sure, but once you add sphericals to everything, it's no problem!

I am definitely in your camp when it comes to do everything right, just wanted to clarify a couple bits I chose to use s14 lcas, z32 uprights and spl offset bushings, and the proper s14 spl toe arm spacers when I did mine. No reason to half-ass suspension stuff, at all.
