Hi all,

New poster here,

I've got a MG Midget that I'm in the process of installing a KA42E engine from my 90 nissan pickup (Truck got rolled, but the engine's still good).

My question is: is the intake on the 240sx any different than the intake on the pickup?

Also, is there any way to get rid of the EGR on this thing without messing up the performance (the midget is a 73 so no more smog) I already got rid of the cat and the air pump thing, but that egr tube is really in the way.

Thanks all

KA powered MG :yum: very cool. Anyways yes the intake of the ka24e in 240sx is much different. The 240sx uses a plenum type intake, and is much better for performance and for your application. It bolts right on so if i were you i would try to get my hands on one.

The egr is removable, just plug all the holes for the tubes into the header, and plug the hole in the intake manifold when you remove egr control unit. It is done same way on both truck and 240, and you will not lose any performance.

Get a header for that E, it will compliment your project and shave a lot of weight. You can buy them on ebay for around 180 shipped, obx brand stainless steel. They are a good header, i run one myself.

Good Luck and be sure to show us all the finished product!

Great,

I'll look for a 240 intake, one of the problems I had with the installation was the top of the throttle body sticks up about an inch and a half out of the hood.

I can't wait till I get it on the road, it only weighs somewhere between a thousand and twelve hundred pounds with the engine installed (I won't know for sure till I get it weighed).

As for the header, I'm in the process of building one for it since there is no room for a stock header.

Since a midget is totally flat on the bottom I'm building a flat (ala nascar) exhaust system for it so I can keep the ground clearance.

I'm not going to be able to keep the stock fuel tank or the stock fuel pump so I'll have to put an inline fuel pump on it. How important is it that the fuel pressure be 43.7 PSI? (The manual says that it's pretty important, but that isn't always the case)

Thanks for the info,
Rick

Man... Me and my brother were considering throwing a KA24DE into an MG B, we've got 3 of them sitting around here and were considering picking up a motor and droppin it in...
Got any pics of the midget?
It'll be interesting to see how the thing turns out :)

I'm not too sure what the differences are from the mgb and the midget as far as the structure goes, but it really wasn't all that hard to get it in the car, it just took a little persuasion with a sawzall. I had to cut out the tranny crossmember and about half the tunnel but I only had to make a couple small notches in the engine compartment to get it to fit.

I'll see what I can do 'bout some pics (gotta warn you though, the car hasn't moved on it's own in about 15 years or so, so it aint pretty yet).

Can anyone tell me how critical the fuel pressure is?

Thanks 'gain

from what i've heard it is pretty important to have the stock fuel pressure. if you are under stock, you will be running lean and run into some problems. If you are over, you will be working the injectors harder than they are meant for. however, quite a few people have run over stock fuel pressure without any detremental effects to the injectors. A fuel pressure regulator very well might be a good idea for you.

Good luck with the car!

Thanks,

I'll see if I can get some pics up in a couple days here.

I get the feelin' I'll be posting here quite a bit in the future.

Anyone see any problems with removing the EGR altogether? Would help clean up the engine compartment a bit more.

none whatsoever. it'll be beneficial. you save weight and clean up the engine bay. Since you don't have to have it, there is no need for it.

Cool...

Anything else you can think of that I can get rid of?

Also, what intake manifolds will fit this engine? I definitely want to go with one of the plenum types but I'm not sure which ones will work.

Thanks again.

There aren't any aftermarket KA24E intake manifolds (none for KA24DE either), so other than stock and custom.
However, Nissan Motorsports does make a KA24E manifold that allows you to run carb's (like dual 44 Mikunis, some others have used Weber 45s), but there are a lot of other parts that also need to be bought, although from the sound of it you may be buying similar parts (like a fuel pump) anyway. Plus a setup like that would be totally awesome in any car. :coold:

What Yugo did you drive? My '87 Yugo was FWD... 4-speed, baby! :bigok:

My dad has an MG-B that he's been restoring. Well, not restoring, more like rebuilding. Did you have to custom fabricate motor mounts?

We've been trying to decide on the v-8 swap... but if I ever swap my motor, and this KA is a fairly straight forward swap, we might do that.

That car is so fun to drive... and right now its only running on 3 cylinders (I believe). Can't wait to pull the engine and rebuild. But, if we pull it and swap it. Mmmmm, that WOULD be fun!

Why a V8? You can get your hands on a KA24E or KADE for pretty cheap on the forums/other places. What about a CA18ET? K20A (S2K engine) ? 13B?

MGs are the best to drive....the funest part about restoring them when I used to do it was the "test driving" :rawk:

I thought about putting a chevy 350 in it and almost did. I decided not to do it because it would entail a whole lot more modifications to the front end than I wanted to do. Besides, this car is gonna be a daily driver and I wanted to save some gas.

Yeah, I had to fab the motor mounts, but it wasn't all that hard. I never drove the car with the mg engine, all I ever heard about it were horror stories, so I decided the mg engine would make a better boat anchor.

Then about a year ago my wife rolled my nissan pickup (I told her next time just hit the damned dog) and I suddenly had a KA24E engine that needed a new home. (by the way, the wife was fine, not even a scratch on her. Scared the crap outa her though).

I've heard a lot of different engine designations since I've been here like s13, s14, ca14,k20a, ka24de etc. Will any of the intake manifolds off one of these engines fit on a ka24e? I would really like to get the throttle body under the hood (it sticks out of the hood about an inch and a half, without any kind of air cleaner on it).

I can't wait to drive this thing.

i say go twin carbed, and lose some electronics:) put ITB's on the carbs, make your header and a nice exhaust, and man would it sound so mean...hell it would be mean too

Rickrak77
06-03-2004, 09:46 AM
Not sure what an ITB is, although I might be able to guess after awhile (prolly something to do with throttle bodies right?)

I can't remember, is the distributor advance computer controlled on this thing or not?

s13 and s14 are chassis designations. s13 is 89-94 and s14 is 95-98
ka24e is SOHC and ka24de is DOHC. The ka24e was in 89-90 s13's and the ka24de was in the later models.

as far as i know only the ka24e intake will fit on the ka24e. they arent hard to find. go to a junkyard or try ebay or call around for scrap motors.

Yes the distributor advance is ecu driven. You will need to leave all inputs/sensors on engine in good working order, to get a decent advance curve. You have the simple option of a vacuum advance, or even an earlier electronic type advance distributor from other nissan/datsun sohc engines. This is what most do when switching to a carb setup or similar.

If you have clearance problems like you say, you might not even be able to fit carbs (webers are a bit taller iirc?). Sticking with oem 240sx efi will give you the most room, as it sits lower than the valve cover.

Heres what itb or, individual throttle bodies, look like

I think I've also read something about using a mechanical distributor out of an older Datsun motor (L28?) when running carb's, can't really remember any more though...

allmotorKA
06-03-2004, 01:39 PM
L28 distributor is for 6 cylinders...you could change out the 6 pronged trigger wheel to a 4 pronged trigger wheel but I think you would still have to remove the drive shaft of the distributor as the L28 is gear driven and not coupled.

Best choice for junkyard distributor is from a later L20B engine like from 1979-80 as these have the electronic ignition ("matchbox") style distributor. Older distributors will use the "points" style distributor which isn't as accurate and reliable at higher RPMs as the electronic ones.

edit:
deviousKA, thanks for the compliments on my motor on a thread from last week...I tried to respond but that thread got locked/banned. Anyhow, to answer your question, I'm running 45mm ITB's as shown in the picture you just posted.

deviousKA
06-03-2004, 02:05 PM
Hope you dont mind me posting your engine pic here and there and using it for reference. I am using 45mm throttles as well, with a custom intake manifold. Hope to get it finished up and installed here soon, ill probably be offering some custom parts/setups for both E, and DE.

I am very Interested in your swap also..I have a 77 Mg Midget..I own a 2009 S 2000..

A friend of mine was selling his beloved Midget, Mint,never has even seen rain..but the trans lost 1st gear and sounds like a straight cut race box when you drive it..

I took it for a spin..what a mistake..I fell in love with that go-kart feel..so connected..

and,2 screws and the windshield slides right out..50 mph feels like 100 mph...The S 2000 feels like a pig now when I drive her..Fast but heavy...

I was thinking a L20B 5 spd swap with a 5 psi suck through carb'd turbo..No efi..The

Built many of these systems back in the day 20 plus years ago...with simple pressure activated fuel enrichment.

Maybe the KA24E is a better choice..

I would like some opinions please

I was hoping the poster was still a member and could give me some insight on his swap and how it functioned..

Also if any other member has done a swap of this nature on a MG Midget..I would like some input..After all we are all car-guys regardless of what we drive..

Prior to my S 2000...I have had several 240..260 Z cars over the years..In my opinion the S2000 even though it is a Honda is just a progression of the 240-260 Z..The new Scion/Subaru is another variation of a early Z car..

I never owned a 510..but a very good friend of mine raced one for years..He thought a suck through setup on a L20B was a good choice ,reliable and bulletproof, no efi..

I want to keep the MG simple and light as possible..

What do you want pics of...The MG..it's just stock at the moment...I am asking the board for their opinion of engine choices and if the previous MG poster had indeed completed his Ka24 swap..I am thinking of a carb'd turbo L20b mtr..for the MG..
