Hey I don't know where to ask this so I thought here would be good. Just got back from the Oregon Trail Rally and was thinking about what would be a good nissan rally car. The s12 200sx came to mind, as it can probably be had for close to nothing and parts will interchange with alot of nissans. Anybody know anything about the old 80's cars? I know they were available with the ca18et, but I was thinking you might be able to swap a ca18det or sr20det in there without too much fuss. Anyhow just wondering if anybody has any info. Thanks

Here is a Yahoo group you can visit for more information.

Technically this post doesn't really belong here so I am going to move it to Classic Nissan/Datsuns (http://forums.freshalloy.com/cgi-bin/ultimatebb.cgi?ubb=forum&f=28&DaysPrune=30).

Good luck finding information.

***I screwed up moving the post; can a mod delete the extra locked one I moved? Thanks***

The standard engine in the S12 was the CA20E. Like you said, the CA18ET was available (at least some years). But also available ('87-'88) was the VG30E. You might want to look into swapping that, or some variant of it.

The VG30E makes the S12 very front heavy... and heavy in general. A CA20E or CA18ET S12 easily weighs less than an S13 or S14, but add the V6 and the weight shoots over 2900lb due to not just the engine but related components. Still, you can't beat 3.0L for outright grunt.

The S12 was Nissan's last really successful rally car, the Pulsar GTiR never really got a chance.

If you intend to swap to a DOHC/turbo engine, start with a turbo car or V6. They come with the R200 (vs. R180), and the V6 has bigger brakes and five lugs.

All s12's with IRS had the R200 differential, only the ones with the 4-link live axle had the R180. However, only 84-86 Turbo's had LSD.

Can always shove in the infamous FJ20ET in the car since the S12 was offered with the FJ in Japan.

Or you could shove in a Chevy 350...it's been done before (Unstable Hybrids Jason's old S12).

My '86 200SX service manual went into depth about the independent suspension and the R180 - together. My '86 NA had an R180 and an independent suspension, I am 100% sure of this.

No 200SX delivered to the US had a limited slip differential, that I know of. I wouldn't be surprised to see one in a Canadian model, though.

Just a thought, ive seen many datsun 510 rally cars! They a nice small light car. You can put a nice z22, z24 block in there wid a l20b head or even a ka 12valve head and it'll be a nice ride. Or do what im doin a nice ka24de 16valve conversion!! gonna be sweet when it gets done. Im gettin the engine modded up .. longways from being done....sigh

anyways just a thought

You were at OTR? So was I.....and guess what I drive 85 S12 Turbo...I think this is a sign to turn it into a rally beast:) Then again I think that about every four seconds anyway. So where is Mabton? I'm in Vancouver. http://www.geocities.co.jp/MotorCity/9185/rally03.jpg http://www.geocities.co.jp/MotorCity/9185/rally06.jpg RWD competition http://forums.northwestnissans.com/attachment.php?s=c6207f0177a2ddacc2dc89bf849ec817&postid=14882 http://forums.northwestnissans.com/attachment.php?s=c6207f0177a2ddacc2dc89bf849ec817&postid=14880

O yeah and on the topic of engines...well it depends on what class you want to run. With adjusted displacement the stock U.S. Turbo Slots into Production GT...which puts you into competition with the turbo scoobys. Hillside 200sx (http://www.rallyracingnews.com/teams/sk-nissan200sx.html) but he's running in group 2. a better comarison is this sube (http://www.rallyracingnews.com/teams/kennedy-subaru.html) stock s12 has 125hp and 135 lb/ft at 3000. Weighs in at aprox 2600 lbs plus cage. Here (http://www.scca.org/amateur/performance_rally/)is a basic version of the class setup. The adjusted displacement is X.7. THe best would be to convince the judges to accept a Jap stock CA18det'd into production gt. 99% chance they'd laugh you into Open. I'm not sure if group 2's boost prohibition is limited to non factory turbos or unliateral, but that wouldn't be a bad place for a CA18det or an FJ20det if turbs were allowed. However if you look at the hillside 200 he's runing a NA FJ so I think turbos are an over all no-no.

I'm thinking of doing a season of rallycross after a fresh engine (mines fairly wheezy at the moment). If you get your hands on a nice S12 you should try some rally crossing first. Gets you some rally connections and is $cheap$.

try http://www.club-s12.org

the US model cars had either the CA20E or the CA18ET. some later ones had the VG30.

the CA18ET can be built up to around 200HP reliably with the stock turbo just need things like a BOV and intercooler and a boost controller.

the S12s feel faster than their mere 120HP #s would suggest with the CA18ET due to their 4.11 axle ratio.

the CA18DET is darn near a drop in swap and has as much if not more potential than the revered SR20DET (400HP reliably on stock internals). the SR20 is also a pretty easy swap

umm.. no. about the potential. no. simply an issue of breathing.. ask any CA person here in the states that has built their CA18DET. pistons. etc.. and ask what power they are making and AT WHAT BOOST. that motor moves air.. just not enough.

compare port size on the exhaust. vs- an SR.

sorry. CA is cool, driven 3. dropped 1. not very impressed compared to an SR.. especially stock for stock..
on top of that.. CA manifold and its goofy intake system is a ***** to work around.. only saving grace is its injectors are topfeed. thats about it.

not knocking the CA- just your quote:

"the CA18DET is darn near a drop in swap and has as much if not more potential than the revered SR20DET (400HP reliably on stock internals)..."

as for my CA friends-- they sold them (ray, rock, paul) and have SR's now.. go figure- and rock's motor was badass for what it was.

so was ray's (btw- dont put pistons in backwards!!)
