At least I’m not the only one with a low boi , I got it up a lil bit higher by taking a air hammer with a flat round bit to the tunnel bracing . But definitely going to have to make a lil skid plate for it just Incase :

I just raised my car. Mine was about a half inch off the ground. oh well, just going to live with it. im more affraid of hitting something hard and shattering it. scrapping isnt so bad.

I def will be making a skid plate just so nothing hangs up on that protrusion, even though my car will never be THAT low.

That looks cool, and expensive as fuck for a bellhousing and slave.

True. I’m just dreading having the bash firewall and trans tunnel while working on the ground

Uhm doesn’t it also come with the flywheel, clutch, and shifter? That’s not a bad price for everything.

What transmission mount do you use for the maxworx kit ?

jumpman2334

so, would it be safe to assume that the s9 kit will still have the 'hanging below the frame rail' problem in an S chassis? im not sure about ya'll but a trans hanging that low would be a deal breaker for me.


its weird that there are so many good (Japanese) power plant options, but each trans option available has weird quirks associated them.


im sure you are aware, but marlin crawler offers a rebuild service that has got to be much cheaper than getting a brand new r154.

So how many folks are still on the 4.08 FD?? How crappy is it on the highway spinning 3500RPM @ 80 MPH??

I am struggling to find s 3.69 and do not want to go as low as a 3.54 from the Q45.

Highway speed calculation @ 3500 RPM in 6th with a 25" tire (255-40-17) is right at 80mph. Thats a bit much

With a J30/3.91 its 3350 @ 80 MPH (80 is the target as thats pretty much highway cruise speeds around here)

I'm sure it's not bad, but getting a used r154 for $1k+ without the damn bellhousing, then paying to rebuild it is about the same as a new one.

Sorry to input. How do guys like the 4.08 FD with the CD009 n a SR??
This is to add to my post above


I still cant believe rebuilt R134 are fetching close to 3K when a CD009 could be had for less than 800..........Blows my mind

jumpman2334

damn, you right. I thought they were more expensive.

di-devol

I'm 1j with the 4 fd. It's short af, I just treat 2nd as 1st.

3500 at 80 isn't bad at all. My bone stock 04 Ralliart daily driver does 3500 at 80mph. These engines are perfectly fine sitting at 3500 for extended periods.

Its not the engine is the issue. I just simply do not want to cruising with my turbo setup at such relatively high RPMS as that means instant boost any time I even breath on the throttle. Also, it just becomes annoying as now everything in the car is buzzing. That is fatiguing for longer than 30 mins commutes. No thanks

R3b

Though im not CD swap yet, I feel this. I daily drive my hatch with built ka-t but driving more and more lately I cant stand the gearing and I have j30. Im about to swap to 180sx vsld since my diff has so much play im dreading the install since its an even higher final drive. Gonna be a temp thing till I do the q45 swap because cruising on the highway above 3k in regular traffic is nuts...
Plus I want to do a road trip from south fl to tail of dragons maybe this year.

So instead of going through 2 or 3 diffs why not just pony up and get a Z diff and axles with the lower ratio that you're after off the bat?

But why would you do this?? The Q45 is available in 3.69 and 3.54 ratios to cover those basis without requiring diff bushings or having to modify the subframe for it to fit.

Which leaves me with these few questions

1) Does a standard R200 diff (say ATS carbon or even a HLSD) swap into the Q45 diff housing?? Its obvious the pinion shaft bearings are actually bigger/longer/etc in the Q45 vs the standard R200 (Z32, 240sx, J30) diff.

2) Can a standard R200 diff (again, say S15 HLSD or ATS carbon) swap into a 350Z R200?? I suspect the answer is yes as a direct swap??

beems240sx

You sound like a Miata owner. I have a mystery diff in mine and at 80mph im about 4K rpm and the car creeps up in temp running like this for a while. I will be going 350z diff and axles mainly because the axles are stronger and more readily available. I rarely drive on the highway, around town the short gear ratio is super fun

LOL @ Beams. The answer is always Miater, no

Got any idea on my Q45 and 350Z based questions by any chance??

beems240sx

I do not know, but honestly I would rather use the diff that Nissan intended the transmission be paired with.

__________________

Because the Q45 diff is 25 years old, annoying to source, requires a Z32 axle or some machining know how, and I've seen them explode.

Also for what it's worth if I played the S chassis game again I'd do the 8.8 IRS setup and call it a day personally

No, you can't put 350z R230 gears into an R200. Yes, you can swap any R200 gears into any other R200, Q45 or whatever.

sidenote, if you have an s14 subframe in your car you can swap a 350z R230 with only conversion bushings. An auto trans 350z R230 will get your 1st-5th the same as they were with stock transmission & diff, 6th gear will be another overdrive. That's what I plan on doing whenever I put the CD in my car.

OK. But that doesn't answer my remaining questions hanz . Also, the JY close to me has 2 Q45 diffs, so yeah, I can grab a Q45 carrier/full diff

I have here with me
Z32 full diff
S13 full diff (has S15 LSD inside)
ATS 1.5 carbon pumpkin with J30 stub axles with ABS tone rings


What I want is
Q45 (be it 3.69 or 3.54 FD)
Either the HLSD or the ATS carbon diff to be swapped in
Z32 rear cover

So I am asking if I can just swap in either R200 HLSD or a ATS carbon into a Q45 (swap ring gears, side bearings, etc) and go without any other component needing change (of course, running the proper stub axles for the diff, which in this case, for the ATS would be J30 or for the S15 would be S15)

RalliartRsX

You are not understanding my questions (or which diffs carry which ring gear size). All the diffs in question are R200. Also please fix your terminology. What "gears" are you referring to??

Also, you have your diffs entirely incorrect. ALL 350Z diffs are R200. ALL Z32 300ZX TURBO diffs are R230. Also, you CANNOT swap any R200 "gears" into a 350Z. The actual ring gear, and pinion are of a different design

Not to be a dick, but please do not comment if you are going to just muddy the waters and through everything off.

I am asking

1) Can you swap a R200 pumpkin (say ATS 1.5 way or HLSD) into a 350Z diff (so basically swapping the ring gear onto the ABS pumpkins above)??

2) Can you swap a R200 pumpkin into a Q45 (keep in mind, the Q45 pinion bushing is larger in diameter than the standard 240SX/J30 diff)
