4afe Into Ke70

[Old fella]

G`dqy all, can someone tell me for sure whether a 4afe can be fitted into a ke70 please. My 4kc is just about past its prime and I happen to have a 4afe at my disposal. I have had a look around thenet and it seems to be a possible swap except for the dizzy at the back. I`m aware that there will have to be a cut and shut on the inlet to get it facing the right way.

Any info will be appreciated.

my understanding is that the only real difference between this and a 4age conversion, is like you have mentioned the distributer and the manifold.

 

though I'm not sure what you would do about the exhaust, a quick google search reveals the 4age manifold wont fit. so youll need something custom, unless you can make the standard one work somehow.

 

so unless you can move that dizzy out of the way for cheap, and find something cheap for the intake/exhaust. you might be better off getting a 4age and be like the rest of us.

Thanks for that mate. I`ve had differing opinions and I`ve almost decided to put it in the too hard basket and rebuild my 4k.

I wouldn't really throw it in the too hard basket, there's ways around the problem. The 20v 4age has the dizzy at the back of the motor and yet its used in rwd cars.

The firewall can either be modded with a hammer or properly with a grinder and welder

Or for a little gain in hp and less time rooting around with the dizzy is to upgrade to crank angle ignition. But you'll also have to upgrade the ecu cause the stock one wouldn't be able to read the new spark readings

 

And another thought is that the suzuki swift g13b twin cam has the dizzy at the back of the motor and a right angle adaptor can be bought for when the motor is used in a rwd car such as the serria. But i don't really know how much of a chance there would be of getting one for the 4af

If he has a motor lying around, and thats why he wants to use it, do you think he would want to go and spend over a grand, maybe 2, on an aftermarket engine management system? If you are going to that extent you may as well buy a Silvertop, as you will be doing all the work to fit one for a lesser result.

 

Firewall mods are the silliest way to make it fit in my opinion. Hammering it is just plain cringe-worthy, especially to create the amount of clearance that you need for the distributor to fit. Removing it is the only option. However it doesnt make much sense to spend 3-4 grand all up to fit a motor you had lying around.

Hear hear...

 

Especially when, for that couple of grand, it'd be easier to find someone's unfinished project 4AGE/TE/ZE that has had the RWD mounting work done already, and will quite likely have a T50 behind it, ready to try and bolt in.

 

either way, we won't judge you if you decide that the engine you got laying around is worth putting into your KE70, as it would still be a decent power upgrade, and shouldn't be as hard on fuel as a 4AGE would... All depends on the results you want, and how much you want to spend to acchieve them.

And thats why i added the "but"

And for a another but is that the commodore delco is crank angle ignition and it can be used on a 4 cylinder motor. BUT the programming needs to be re-flashed.

Just an option. Maybe i should have said that i have a rough idea on the size of the dizzy and a rough idea on the space between the back of the motor and the firewall...

I don't care much in the way of it but it was just an option...

And another thought is that the suzuki swift g13b twin cam has the dizzy at the back of the motor and a right angle adaptor can be bought for when the motor is used in a rwd car such as the serria. But i don't really know how much of a chance there would be of getting one for the 4af

Last time i looked, which was a few years back the g13b right angle adaptor was around the $150 (I think) mark

 

Maybe it should be thrown into the too hard/why bother basket

 

I was just throwing in some extra thoughts/options thats all for the guy to think about and search up on as to if its worth while or not

G`day again and thanks for all of your valuable comments. What I should really have asked in the beginning is ,has someone actually done a 4afe into ke70 conversion and can they comment constructively. I don`t just have a motor "laying around" so to speak, I have a complete ae 92, running and in very reasonable condition for its age. That car only owes me a couple of hundred bucks and it seems a better idea to me to transplant that motor rather than rebuild my 4kc and still wind up with less horsepower and reliability. I am approaching 60 years of age and am retired so time is not a problem, I have a well equiped workshop and really enjoy modifying/manufacturing stuff. The ke70 is a project that I have waited a long time to do and has taken some 6 months so far, to get it to the stage that it is. It will never be a show car and was never intended to be. Just something to have a bit of fun with and to break the boredom.

Again, thanks heaps, but lets keep it relevant to the original question.

[ke70dave]

seems we have all misjudged you a bit, sounds like your on the ball already.

 

and since...

time is not a problem

 

megasquirt ecu?

 

few hundred bucks and a whole lot of reading and you can have an aftermarket ecu to make your 4afe push the ke70 along.

 

megasquirts are great and might just suit your application. great project as well!

 

i hope I'm still playing with rollas at almost 60!

[Instigator]

If you're going to the trouble of pulling the motor out of a perfectly good car then my 2 cents is sell said car and use the money to buy a 4age.

 

You're going to have to stuff around with fuel system etc either way so might as well go for the better motor, they can be had for a few hundred bucks.

 

There's a complete ae82 with a bigport in it on here or 86dc for $600 and it's been up for a while so you might even be able to get it cheaper.

Just something else i realised is that the 4a-f that i used one time in my old '82 was that bosses for where the rwd mounts go didn't have them tapped out for the bolts....
