3.0L 240 sx ????? can it be done???

Post by **240can** » Mon Sep 23, 2002 5:12 pm

anyone ever thought of this?. i think that it would solve the huge power problem we all have...... MAYBE

Post by **1991240xs** » Mon Sep 23, 2002 5:12 pm

are you talking about the 300zx engine?...because i hope you know a 240 can't be overbored to a 3.0L...the biggest you even need is a rb26dett...i dunno...you only have 2 posts so i won't bug you on this one too much..but it hasn't been done yet with the vg engine-

hrmm solve the power problem "we all have"

yep i got a solution....its called an ES AR TWENTY DEE EE TEE!!

Post by **flip240** » Mon Sep 23, 2002 5:12 pm

In other regions of the nation, we pronounce it KAY A TWENTY FOUR DEE EE TEE!!!

Post by **Chance** » Mon Sep 23, 2002 5:12 pm

It has been done, if you mean the 300ZX motor. Lots of custom fabrication was done

I would wonder, however, if you could direct swap the N/A VG30 from a nissan truck of the same year with an S13? Maybe you would have to use the truck's motor mounts? Anybody know?

ez way to get more power.. go buy a huge vinal sticker.. white = 50HP , chrome = 120HP.. most it will cost u is like 40$..

you can make the rb 2.6L engine into a 3.0L, i was reading an article on this team who was overhualing an rb2.6, they said something about taking the bottom half of another 3L engine and using it in this one, they ended up spending $25,000 (apart from original cost of engine) and got close to 800hp out of it, cant remember torque, maybe 600+

If your talking about boring out the KA24 block, I believe 2.8 liters is as large as you can get it.(correct me if i'm wrong)

Post by **Bizz** » Mon Sep 23, 2002 5:12 pm

You could always buy a S12 200sx with the 3.0 from the factory.

Post by **slw240sx** » Mon Sep 23, 2002 5:12 pm

go with yellow vinyl thats 80hp 30hp more then white dont forget the wheel covers with crossdrilled dust cover thats another 20-65 hp

you can stroke the rb's up to 2.8L i've seen. It would be easier and cheaper to tune the rb on its original discplacement instead of doing all that custom work. A GINORMOUS turbo would be cooler than a overbored rb imo

hahahha 300zx motor in a 240?

never its impossible nobody will ever do it :-) ;-)

Post by **mojo22** » Mon Sep 23, 2002 5:12 pm

if you are talking about stroking the actual block of the rb26.....i would suppose you can on go so far as to a 2.8.....just a guess....but i do know there is a jdm truck block that is 3.0 that they can build in order to get a little more displacement for the same build. so, i know this doesn't have anything really to do with putting a VG motor in.....but just a little 411 for you all

Post by **kool-aid54** » Mon Sep 23, 2002 5:12 pm

I measured the engine bay and an 89 240's engine bay is HUGE compared to a 90 300z. So size wise its possible, I haven't checked the motor mounts yet but I'm going to look into it. I have a wrecked 300z in my garage and I'm thinking of making a 240, 300z hybrid. I want to swap body parts and engines along with drivetrain.

Post by **prior** » Mon Sep 23, 2002 5:12 pm

hehe, how about a 2jz? ive seen a 1jz swap and the motor looks like it belonged in the car.... well, except for the whole toyota thing

Post by **barrigas14** » Mon Sep 23, 2002 5:12 pm

instead of boring out a Rb26 why not just buy a RB30E and put a Rb26 head on top of it.

btw the 2.4L KA is already big enough. the VG30DETT will be a pain in the ***...it is already a pain in the *** for the 300zx guys.

Post by **mbeach** » Mon Sep 23, 2002 5:12 pm

BYP had a VG30DETT S14 a while back I believe. Heck there's even a few 510's with VG30s running around.

Why you would do this is beyond me however.

Post by **PhaneSoul** » Mon Sep 23, 2002 5:12 pm

how much can the ka be bored out to? is 2.8 the most or can it goto 3.0? ive been wanting to look into this for a while, but no time to do muh research....

Post by **SeVa-S13** » Mon Sep 23, 2002 5:12 pm

It can go to 2.5, max. Our engines aren't domestic smallblocks. We don't bore and stroke and all that crap. The KA's cylinder walls get too thin after that and for all intensive purposes, the KA is already stroked.

Post by **barrigas14** » Mon Sep 23, 2002 5:12 pm

why...the biggest you should go is 2.5. there is really no reason though. just keep it 2.4 and you will be fine. hell even know adays the KA is still one of the larger I4's out there.

Post by **Zydeco** » Mon Sep 23, 2002 5:12 pm

The KA all ready revs realy slow and if you made it 3.0L's it would rev so slow it not even be funny...Well maby it would.

Post by **fatboy** » Mon Sep 23, 2002 5:12 pm

how much can you bore a ka24 before you run into the water jackets?

Post by **k6kicker** » Mon Sep 23, 2002 5:12 pm

dude even 2.5l is pushing it, this motor is pretty much at peak displacement as is (why do you think it has no top end, its stroked to kingdom come)

Post by **k6kicker** » Mon Sep 23, 2002 5:12 pm

btw headswapped 3.0 rb's are yummy

Post by **PapaSmurf2k3** » Mon Sep 23, 2002 5:12 pm

if you are hellbent on boring and stroking just swap in a 350 and call it a day. more power than a vg30 anyway, if your gonna do the swap you might as well go all the way.

i would love to see the pain in the *** and waste of money that would be. those engines are pain in the asses to work with in the 350z...just think of how much more of a pain in the *** it would be in a 240sx.

Post by **christopher** » Mon Sep 23, 2002 5:12 pm

I'm pretty sure he meant a Chevy 350 not the VQ35

Post by **PapaSmurf2k3** » Mon Sep 23, 2002 5:12 pm

christopher is correct. what im saying is there are much better alternatives for engine swaps than the vg30, and that is why it isnt really done that often. sure it would be powerful, but only after you dump a serious ammount of money into it that could be better spent elsewhere. It doesnt really hold any value except the fact that you can say "yeah i have a vg30 in my 240"

forget teh cross drilled rotors the spinnin hubs, those get you the bling power for all the sistas. and they add like 15 hp. my friend put on GTR powered badge on his accord and his 1/4 mile time was like 2 seconds shorter then stock. its crazy...
