200sx rb20det swap?????

[driftnslide1]

a friend of mine has bought a 86 Nissan 200sx with a ca20e. not the best choice, but it seemed perfect for a sweet beater and first drift car . something he didnt have to worry about crashing at the $300 asking price( he has another DD). he had it for a week and hes got his gotten a rb20det with no transmission but with the ignitor chip and the computer for $500. what transsmissions are compatable with this combo. ive heard the 300zx transmission will bolt but wont fit in the tunnel. anyone know anything about the s12?

[Myetball]

Won't fit in the tunnel? That's what plasma cutters are for

I'd be more worried about getting a transmission to fit the engine than making it fit in the car.

Had an '87 S12 w/VG30E many moons ago. Best handling car I've ever driven....even when the azz end was hangin' out

Crazy thing was, when drifting I just pointed the front wheels where I wanted to go and let go of the wheel. Within limits the of course, the front wheels would stay where I wanted while the azz end danced around.....was friggin hilarious....especially when passengers were freaking out

The problem wont be the transmission, but getting anything other than the rb20 bell housing to bolt up to the motor. I think you should be able to scrounge up an rb20 transmission and bell housing pretty cheap.

Shens, it fits just fine! My friend who posts as Draconis actually got his car featured in a magazine after his RB20 swap.

He posts up here: http://www.club-s12.org/

Awesome! I'll bet good money that car is just too fast.

[turbodcivic]

omg, thats so f*ucking badd asss

[themadscientist]

The RB in the S12 is IMO one of the coolest swaps, they just look perfect together.

[dash]

RBs are good motors, but.... I'd never take one over a boosted VG30ET, certainly not a rb20, plus the VG already OE in that platform.RB25/26 can be fast... at a price; expensive to mod, parts availability & I've seen oil pump issues leave teethmark$$$ in a few friends 25/26 S13s.VGs have no such problems. Smooth, rugged, hella reliable, 3.3L avaiable and they make all the torque you could want. Monster?This one put down 480+ ft-lbs tq at the tires; pump gas, $450 turbo upgrade (60-1), nissan ecu, heavy 3400 pounds still goes mid 11s

This done 700+ on stock pathfinder block iirc

It ain't "JDM-mad-tite-yo" but the 'jurassic VG' gets my vote

[themadscientist]

VGs are nothing but victims in Japan. I have never personally met a VG that I couldn't beat with something as simple as a boosted up RB20 and the heavy-hitters at the organized drags never make it far up the ladder. They are a novelty at best on this end.

I definitely agree that they are a better choice in the S12 from a practicality standpoint though. I can't image trying to support an RB in the states.

[dash]

yeah, VGs are highly underrated. Most have no clue of their potential.If you 'rub 'em right', they can be nasty customers.

I found an old issue (~2001) of Sport Compact Car magazine laying around, featuring an old '84 300zx. Authors' words: "soiled passenger seat... fastest street car.... frightened senseless...." were words used to describe its acceleration.When one considers that the best of the best import monsters are thrown at these guys for evaluation.... says ALOT about the ol VG.

If anyone remember nissans finest motorsport moment, it was the dominance by the infamous #83 GTP car that beat the best the world threw at it - retired after an undefeated season! Many *think* it was the twincam motor (VG30DE)..... it wasn't. Same ol' 2 valve mule.

I remember a z32 hillclimb car making a naturally aspirated 900hp in endurance form. it used the single cam vg30e and all the parts were *supposedly* available from nissan motorsports america.

[themadscientist]

On the surface the VG30ET looks a bit more rugged than the VG30DETT and most of the notable VGs I have seen were the SOHC variety. They were chain drive cams vice the DOHC belt drive right?

[r34 gtr]

I believe so. I'm pretty sure the vg33e in my friend's xterra is a chain drive. There just doesnt seem like theres room for a belt.

[dash]

All VGs are belt driven. 30/33 prts interchange. Later VQ on have chainsAt any level VG has gotcha covered.I'd imagine the path to a boosted VG/200sx would be cheaper & less headaches than a RB conversion. Plus side;Partsavailability of a 'cheap' replacement if something goes wrong.More durable, more torque, far more potentialShorter motor doesn't have the 'extra' cylinders ahead of crossmember

No doubt an RB20 in this hull would be an entertaining ride.Not trying to sell anyone on the VG idea.... just mention some points worth considering imo

[themadscientist]

Were I stateside I would roll an S12. I would bring all my FJ stuff though and do an RS clone but if I did'nt have that I would go VG30ET with a blower on top sticking through the hood. I would probably go with the SOHC for simplicity. VG guys school me on the DOHC is it worth the headache?

[dash]

I've owned both z31 & z32. Prefer working on the "simpler" SOHC by far. While it may be "a bit easier" to get 'high' power from the DOHC its also a wider/heavier motor - hard to believe such a tiny vg block hidden under all that.Proven inexpensive recipees get 400+ ft-lbs torque atw from a SOHC tho.Some done it with nissan ecu or megasquirt + upgrading the stock T3 (integral wastegate retained) or a used $250 holset.If they run 11s in a heavy z31, I can't imagine wanting more in the lighter s12.I'd relocate the turbo, like a buick GN.... actually buick turbo upgrades would work excellent on the vg (with its extended rpm range)Back when I had my GN, prices were ~$700 from Precision.... dunno what the Buick scene is like today

[devil_child]

lets see

s12 check

rb20s13 check

hmmmmmm

but i got the crappy 85 b transmission with the cable shifter, so id hafta do a bell swap with a shorter drivehaft. nvm

oh, and no they did not come sandard with a vg30e only a few thousand in the us did. They have different mounts and everything. i will tell you doing a ca20e to g30e swap is nothing short of hard. All that crap makes wiring an rb20 look easy as pie (apple).

tms if i hear fj one more time i will cry.

[dash]

obviously start with a VG car if going that route. I just realized that the s12 ain't no lightweight.This ca20 S12 added ca18det head & bits to ca20 block. Didn't see any mention of what rod & pistons usedhttp://www.twincam.info/index.php?showtopic=2923

[NeedCAforS13]

I would go VG30ET with a blower on top sticking through the hood.

haha I did that. didn't end up getting it running and sold it n/a. but it looked pretty mean :P

[themadscientist]

I had something more like this in mind. Old school with the erndale scoop.Diggin those fender flares!

[r34 gtr]

Dude, that s12 is/was badass!
