well these are my 5 reasons for going KA over a VG

1. the KA is smaller and then a VG.

2. KA's are everywhere, i went to a junkyard and found 5 KA'd cars (3 trucks, 1 b13 or some shit car with a KA and a S13 with a KA)

3. this is more of a old skool engine in a new skool generation and you can do alot to it.

4. parts from other engines swap over (l28ET oil pump etc etc)

5. it's SOOOOOOOOOOOO much easier working in the engine space. the VG is a HUGE engine for a v6.

If you've ever worked on a VG powered car you'd know those engines are a bitch to work on BUT they can be just as reliable as a KA. seen some Z31 Vg's with 350,XXX miles on the original VG.

+1 everything above plus if your car isnt originally a vg you will have to swap the vg cross member and MAYBE the vg mounts.  Overall the ka is an easier swap to do and they can still make pretty good power for less weight of the vg.  Less weight = more speed, better handling, etc.  KA FTW!

i had the idea of putting a ka in my vg, but after doing some research, it seemed like a pain in the ass with the cross member, wiring and the rack and pinion. just not worth it for me. so i got a ca car. since you have a ca car you would have it get the cross member, wiring harness and the rack and pinion for a vg. if you had a se parts car it would be worth it, but if you dont, go with a KA. more aftermarket parts, you can get about anything you want. its a great all around motor. not saying the vg isn't, mine has 250,xxx miles and its still runs strong. its just easier to do a ka

i couldn't tell you that i honestly don't know  

it makes sense to me though the the less a engine weighs the less stress it is on the suspension, and it eats up tires less.

jsut my 0.02

it would be badass with a built n/a vg33, with some nice nasty cams. or even put DE heads on it

drifting a stock engined vg car isnt too bad, but you can feel the weight

Okay, I am really getting tired of all you 'younger' guys worrying about weight in our cars.  Our cars are not light to start with and a SE with all it's extra weight are still very capable.

The KA is great but you will lose the low end torque but it naturally makes up for it in the midrange.  I love the VG, but unless you have all the necessary pieces, I suggest anyone to go KA24DE.  I've owned both types and the KA24DE is a very capable. motor.

the only True S12 that hold the title for the lightest is the 1984 SRA CA20E notch S12.

weighing in at 2,300lbs or 2,400lbs

heaviest is the Se weighing in at 2,900 lbs

it doesn't matter though, the 300ZX moves and so does the VG. both Z and S12 are VERY capable cars you just gotta know what you're doing.

if you know what your doing a S12 can become a absolute MONSTER on the track

http://www.racesilvia.com/cmsms/index.php?page=kori this is an example of said monster

Z32 yes Z31 no

VG30e's have to potential to push allot of power you can even find company's who build 1000 hp vg30e's.
I would say keep the vg.You can push more power and more torque. plus you have more parts that swap within the vg family than you can the ka family. VG33er,VG33et. If I was to do a swap I would go with a vg30de Or vg30dett.

Look at this
z31 vg30dett swap

VG's not the issue VG is and AMAZING engine but it's the engine space in a S12. he's not a Se, so he doesn't have a VG in his, he's asking about putting one in.

it's a very tight fit, even for the Z31 it's a tight fit. and Z32 TT drivers have a harder time working in them.

I use to own a Z31 and did alot of playing. it's a GREAT engine it's proven it's self over and over and over again. but again, our S12's don't have the engine space a Z31 or a Z32 have.

I suggest a VG33ER or VG30ER if you even go the VG route because you would have to cut the firewall for a turbo or you can do it MC's way rear mount exhaust turbo. or just go with a vortec supercharger.

EDIT: I saw the Z31 build thead alot of crap had to be custom made to make it fit.

people who do VG30DETT swaps in S12's are insane and props to them.
