"4G240"

I have heard about people doing this swap but have never seen any progress or forums documenting the swap. Im now into the project far enough that Im ready to start posting updates etc on it.

Here it is:

The day after I found this website and Bill's "Billhousings" I purchased a R154 Tranny for $300 lol.



I heard about a couple of DSM's sitting at a local junkyard so me and a friend went and pulled a 4G63T 6 bolt engine for $100. Got a 2G maf for $5 too. also the engine came with an oil cooler which I later sold for $60 including the housing.



I was going to install the 4g63 into my daily driver 240sx hatch. But I came across this 89 240 coupe for $300. I have been wanting a coupe for awhile now so I was pretty stoked.








The frame in the front was busted. I bought 2 fenders a front headlight assembly and the bumper came with the car. I forgot the bumper at the dudes house so I paid someone $20 for gas money to bring it to me. All of that cost a total of $200. You can see how far off the front frame was.








The first quote I got to pull the front end was $900. I told the guy "I will think about it" lol. I found someone else to do it for $500 a couple weeks later. He really did a good job. And I realize it was alot of work. The hood latches perfect now. All of the fenders are tie wrapped on in these picts.





A couple days ago me and a friend pulled the single cam KA engine. And today I am painting the car flat black. Going to grab some beer and have some friends over for a paint party lol. Here is how it sits now.




I almost have all of the parts. What I need to buy is the actual R154 to 4G63 bellhousing. I am going to use the 10cm (or whatever it is) EVO 9 16G turbo. And someone last night told me he would give me an EVO 8,9 intake for free. Also I need to go grab some motor mounts, a rwd water pump, and im going to use the alternator relocation kit.

Last but not least Im going to grab an EPROM ecu from Jeff at Keydiver. (dsmchips.com) I still have a chip that I can reburn from my last project. We were talking about making an adjustable rev limiter. Im going to be using the car for drifting and racing. So I wanted the option of having a low rev limiter so I could keep my foot on the gas around corners and so that I wont have to worry about my head and stock springs.


Updates to come. Im pretty stoked. Any suggestions or questions are welcome. I have a ways to go on the project but I wanted to show u guys whats going on in my garage lol....

I love real world budget builds like this. That's why mu budget is set at $10k for my whole car. I have a lot of work to do, but this engine/tranny combo is pretty cheap.

Some of the items you might be missing are:
Wiring harness (1G)
2G MAF connector (to adapt to the 1G harness)
Injectors
Fuel pump
Fuel pressure regulator
LSD rear end
maybe some Z32 brakes if you're going racing
Radiator
Gauges etc
the EVO intake may not work (check this site for details)
EVO exhaust manifold (you might pick up a tubular one cheap from Megan or other)

Definitely take care of your maintenance now. Timing belt, balance shaft eliminator, lifters (3G) or other items are really easy to get to now. You could also upgrade your cams and valve springs and replace the valve stem seals pretty cheap. The valves should be good for 400hp and fairly good boost (25psi or so) and not get too hot. A top end can really bring the 4G63 to life and for a pretty low price especially if you stick to used parts or items like cams

Switching to an aluminum flywheel would be a good choice as well. I run a 8lb Fidanza on my Colt GT and it's awesome for quick shifts. I don't know if it will hold up to drifting, but worth a look for the price.

I'd say for another $2k you'd have a decent drift car. That is without a cage or serious safety equipment. Keep us updated and have fun with the project.

Yeah def 3G lifters and a head "rebuild" and resurfacing. Also I think I will use a Mitsu MLS headgasket.

On my 2G FWD I was running 24 25 psi on a felpro headgasket and stock head bolts and a big 16G etc. People would like to say that it will not hold up but it worked great lol..

In addition to your list I was thinking of adding methanol. Ive already got a walboro 255 fuel pump. And a A1000 Aeromotive FPR. It uses a 8 AN fuel line which is pretty much the same size as the DSM fuel rail. Also going to go with ARP headstuds.

Im also going to go with 1000cc injectors and have the chip tune them down. I will probably only use a 50% duty cycle but I dont want to have to think about upgrading for awhile.

I have a Z32 VLSD but im going to rock a welded dif till it breaks haha... And I am definitly going to have to modify the EVO intake. I have been watching the Intake thread since it started. I think I will use a 2G head instead of 1G. Im not too worried about top end right now for drifting. But im sure I will want it when I hit up the racetrack.

If you want to run meth and use that size injector to make power, you might as well skip all that and run E85. I know a lot of guys running E85 and have nothing but great things to say. You can run a ton more timing and run a cleaner fuel. Not to mention, the volume of fuel you run with E85 helps to cool the intake air to keep temps down. You might check it out.

And does the Z32 LSD fit the 240SX? In know the 240 runs an R200 rear end and the Z32 unit is an R230 which is much larger. I'm sure it probably works, but thought I would ask.

yeah it "fits" lol. I have it installed on my stock hatch right now. To my understaning it is a R200 rear just like the Infinity J30 rear. Altho the J30 has an extra sensor attatched... But you are probably right, it is probably a R230?

Either way, I used the axels from the 300zx. It really was an easy swap. The rear end doesnt fit the same as the stock one but it works. Im welding one of my stock difs right now, we'll see how it goes. A poor mans 2 way.

EDIT: Actually I think it could be called the "R200V"

Thats the one. R200V. It works alright right now. But that is in an underpowered car. single cam ka24e. Like I was saying im probably just going to use a welded dif until I save enough money for a kaaz or another 2 way dif.

As we all know the 4G63 will offer plenty of drifting power lol....


In regards to E85, the gas station(s) that offer it in washington state are too far away from where I live. Otherwise that would be great to use.

whats the progress on this i have a 90 240 with a stick base model coupe power nothin. i am looking at doing a 4g63 or a sbc for the proeject. i am trying to find the cheapest build up i can. nissan stuff (doen ALOT of research) ur spending a hella lot of money on stuff tuning is a bitch 4g63 is the easiest engine to tune as for turbo import stuff. the sbc wel der carbed 327.

either project will push 300 wheel hp and 150 shot. this car is for motor chross racign which is kinda a mix of all kinds of racing. your car has to be quick like a drag car handle like an auto x car and be able to go through dirt like ralley no jumping though) so basically the best all around car. mpg i dont care i have a b20vtec si i have been building right now it hasa b16a vtec when this proeject is done i will sport the car in the summer and swap teh b16a2 head to the b20 block and drop it in the si(2000 btw)

so i am trying to price out each swap what is the best band for my buck

v8 or 4g63 turbo ( a 4g64 turbo would be cool too but more money from my understanding)

also as far as weight that is not a factor - all i am looking for is prices here.

harness $$$
motor $$$
tuning$$$
what tranny? plus adaptor plate or anything else like that? $$$

i gots the money but i want to spend as little as possible.

Hey, DoubleJ

It seems you have some competition from me now in the 240 area. Very Happy

http://img.photobucket.com/albums/v300/Arktis/IMG_04971.jpg
http://img.photobucket.com/albums/v300/Arktis/IMG_05201.jpg

However, yours was more complete from the get-go.

Nissan has too many SR fanboys. If you do the math, it's FAR more cost & power effective to do a sirius into a 240.

Plus...why wouldn't we? 240s are just so LIGHT and have so many suspension mods. Put a good motor to a light chassis and it'll scoot. Ignore the others.

How do you know if a 240 is LSD? I'll be junking out a 240 rear from the civic project, if it is lsd, It will be for sale.
I'm near Memphis.

update. I am working on getting a clutch / motor mounts. this project is coming along slowly but surely. I have everything else. I am using a 2G head with Evo Intake manifold and EVO 8 16G. Possibly upgrading the wheel to a 20G or equivalent wheel. I found a guy who rebuilds / balances turbos for cheap.

Some random "update" picts:

Hyundai Valve Cover. Before Paint.


After Paint



2G Head / evo intake (umm single cam j/k)








Temp Mock Up. LOL

was there any overlap on the head or the runners?


I was under the impression that the runners were vastly different. I remember there being a little dimple or dip at the bottom of each runner.

More pics please.

You are asking about the EVO manifold right?? And I am using a 2G HEAD to match up to the EVO manifold. Just got the head back from the shop yesterday.

Here is the overlap on the Gasket


Overlap on the head.


So I figured i would just cut out what is in the way.





So now I need to just throw some alluminum in there and have someone weld the holes shut. After I do that I will take it to the machine shop and have them resurface the manifold.


Painted the manifold black.

Sounds good......


I am using mighty max motor mounts + we are going to build some custom mounts. The motor mounts right now actually line up pretty close. I just need to move the whole setup towards the firewall about 2-3 inches.

Teaser Pictures:
(I need to get some REAL lighting in my garage)

I wanted to know if the trans lined
up by the shifter hole or did you have to
extend the shifter lever? I am in the process
of lining up my parts to do one in a s14
with the Evo viii motor

Im using mighty max motor mounts, and with them sitting on the s13's stock motor mounts (yes I pretty much bolted it right in with no mods lol), the shifter sits pretty far forward of the hole. we are talkin 5-6 inches. I have plenty of room on the firewall side. What is getting me right now is the crossmember/power steering lines.

I am going to move the pwr steering lines and possibly cut the lip away from the crossmember to get the motor to sit as far back as possible. I will definitely be fabbing/buying an extended shifter lever...


I just bought a 90 Talon with a bunch of goodies I am going to use on the 240. Once I get that car out of my hair I will be resuming mounting the engine. So much to do and no time! lol

You say 6-7 inches in front of the hole.

That's good news for me, since I'm using an RX7 trans for essentially the same project.

Keep us updated.

Subscribed. I am very interested in attempting this swap as well. Having someone else attempt it first will provide a lot of useful information. Get crackin'! Haha.

One of the main concerns with using the R154 transmission was that the shifter was wayyyy off. You mentioned moving the motor and trans physically backwards in the engine bay, but like you said, you run into issues with the subframe and powersteering lines. I wonder if there might be another option as far as transmissions go that would locate the shifter closer to the stock location. I've heard of using the GM T56 trans. Any thoughts? I don't think anyone makes a bellhousing adapter for it yet though so it would have to be a one off custom adapter.

I see you're using the Evo intake manifold, that takes care of reorienting the throttle body to the correct side, but what about the exhaust manifold and turbo? What are you going to do to reorient them?

I assume you're going to swap the water pump for a RWD pump. What about running heater/coolant/radiator hoses?

How about powersteering lines?

Sorry for all the questions. Shocked

Bill Hincher on this site has finished the 4G63/T56 bellhousings. the T56's shifter will sit three inches further back than the stock truck 5 speed- im not sure about its dimensions compared the the R154.

The stock exhaust manifold should work, but you have to rotate the turbo 180 degrees, and then split the turbo apart and rotate the housing so the oil drain faces down.

using the truck pump is one way to go, but i have heard of people running the car pump/waterpipe and run long hoses to the back of the engine bay.

I wonder if there might be another option as far as transmissions go that would locate the shifter closer to the stock location. I've heard of using the GM T56 trans. Any thoughts? I don't think anyone makes a bellhousing adapter for it yet though so it would have to be a one off custom adapter.

I see you're using the Evo intake manifold, that takes care of reorienting the throttle body to the correct side, but what about the exhaust manifold and turbo? What are you going to do to reorient them?

I assume you're going to swap the water pump for a RWD pump. What about running heater/coolant/radiator hoses?

How about powersteering lines?

Sorry for all the questions. Shocked


Power steering lines really wont be a big deal. I can have lines made etc. The exhaust manifold and turbo have plenty of room.

This picture is with the engine leaning to the passenger side a little. with the motor centered this would create an inch or so more space. this is the new setup Im going to try. Its a garrett 50 trim. I just flipped the turbo on the exhaust manifold to face the opposite direction and will just clock it to where it needs to be for the IC piping. And in the picts one 240 motor mount bolt is in the mighty max motor mount. the other one is close and i could get it in with persuasion if I had to.








Blurry picture of the Tial BOV mockup:




I have read a forum on here about a shifter extender you can buy online. I havent looked into it enough to see how much it cost etc. In addition I think someone has a forum on transmission lengths with pictures etc.

I have heard and read about 4G63 240's. Or people sayin "i had a friend that had a friend who did the swap." And everyone that posts on nico or nissan forums get chewed out and flamed. Everybody will be rockin RWD 4g63 240sx for drifting soon! Just wait lol.

Isnt the T56 transmission Auto? Im not 100% familiar with the transmission. Or you can probably buy a "click" shifter for it I would assume. I guess it depends if you want to drag / drift / autocross. I went 5spd mostly for drifting.

Bill Hincher on this site has finished the 4G63/T56 bellhousings. the T56's shifter will sit three inches further back than the stock truck 5 speed- im not sure about its dimensions compared the the R154.

The stock exhaust manifold should work, but you have to rotate the turbo 180 degrees, and then split the turbo apart and rotate the housing so the oil drain faces down.

using the truck pump is one way to go, but i have heard of people running the car pump/waterpipe and run long hoses to the back of the engine bay.


Oh I did not know that. I was looking on his website, but I only saw info that it was still under development.
So the T56 would place the shifter within two inches of the stock shifter hole. That's much easier for me to work around.

Nope. It's a six speed manual that comes in Mustang Cobras, Vipers, Camaros/Firebirds. Pretty strong stock transmission.

So you're using the stock 240sx mounting points with Mighty Max motor mounts? And it bolts up pretty well?

I'll see if I can dig up the info about the transmissions on here.

What about the water pump? Are you using the stock one and some long rubber hoses or the truck water pump?

Link to info about the shifter extender?

Ok...considering I was looking to do a 1jz swap a while back on the 240 I had I'll help ya out a little. I believe it was from a toyota soarer or chaser...cant remember 100% right now, but it also runs a r154 trans. The only difference (drum roll)...is the shifter is about 4?? inches or so further back than your standard supra shifter/tail housing. How you get your hands on one is to have a friend in Japan, buy a chaser tranny with it already on it Wink, or find someone who is selling their custom setup. There is also a company out who is looking into producing aftermarket version, and it may be done now...check out 2jzswap.com for more info on the R154 stuff.

So the Soarer/Chaser uses a longer tailshaft than a normal R154.
I've got some buddies in Japan. I'll see what they can dig up for me.

I'm sorry if this seems like a thread hijack, but I really don't want to create another thread in the mechanical section to post this picture.

If what DoubleJ said is correct, and the motors are just about bolt-in, but he's having trans issues, then this could possibly be a solution.



Above is a KA24DE transmission
Below is an S4 RX7 Turbo II w/ B2600 bell.

Note how close the shifters are.

I'll pull out my B2600 trans tomorrow to compare the tailhousing on that to these two, for future reference and for others that seek to do this project.

Also, sorry for the quality of the picture. It's from a cellphone (obvious at this point). Sad

Oooo that's very helpful! How much power do TII transmissions hold? The B2600 bellhousing bolts up to a wideblock right?

Thats all good and fun that the transmissions are the same length or the RX7 is a bit longer. But that only makes a difference if u hooked the RX7 trans to a KA motor. You still might have the same issues because of the oil pan with the 4g63 / RX-7 combo. What you need to compare is R154 vs the length of the RX-7 transmission (since i used the R154 and was inches off the shifter hole).

Or just throw it in the engine bay and go at it! lol

What oil pan issue are you referring to?

I was thinking if you're using the stock mounting locations to mount the 4G with the MightyMax motor mounts, then how different could it be from the mounting position on the KA? Therefore the RX7 transmission being very similar to the KA transmission becomes relevent.

Well, aside from whatelse I'm reading, this is on PZG's Model R page:
Quote:
The Mazda Model R transmission is a great option for use with wideblock engines. It has been used in RX7s with over 500hp and can handle revs over 11,000rpm


So unless you're doing a drag car, the TII trans seems to be a good option.

Plus the trans itself is cheap nowadays. The bellhousing isn't.

I wonder...you think Bill could start making copies of the B2600 bell if I send him mine to make a model of? (If there's a thread on this, I haven't seen it)

The only issue I saw when trying to determine what trans, was that the TII transmission took over 5 or 600 horsepower, but torque is what breaks tranmissions. The 1.3L rotary doesn't put out near as much torque as the 4g will, and thats why I steered away from it. Plus, I was looking to drag, and not drift, so it was another factor that kept me from looking into it. G/L with your build and trans choice!

Thanks, means alot.

I need to finish it.... but....

I am about to swap an engine into my eagle talon lol. That will take another one of my weekends i could be spending on the 240....


Im not worried tho. It will get done. Winter is coming sooon and I would rather drive my AWD than RWD for when the snow comes.
