4age Into Ke70 / Ae71 Conversion - The Step By Step Noob Guide

[TARAKAN]

hey mate. i gota a question for u. maybe u would know. nobody else does. i got a ke70 with 4 age and so on. but its got a problem. it has no spark. it has power comin to the coil, power going from the coil to the dizzy but no spark comin out of the dizzy and the coil igniter works too. do these motors have dizzy problems or could it be an ecu? maybe it could b something else that u can think of. thanks 4 reading anyways.

anyone have a ke70 wiring diagram?

 

i'm stuck with my 4age into ke70 build atm

[ketowagz]

hey I found a 4age from a wrecked ae92 with k50 gearbox. for only about 600 bucks would that be alright to change to rear wheel drive and put it in a ke70. what else needs to be done?

[the_van_can]

if it's from AE92 you will need to cut and shut the intake manifold or get a rwd intake manifold with an adapter plate. you will also need to install a spigpot bearing into the crank,

the wiring loom will have to be heavily modified as if is for fwd instead of rwd (you could just pay someone to do this if your not confident). You will need to source rwd engine mounts from an

ae71 or ae86, then everything else in this engine conversion is straight foward, you will need a pedal box from an ae71/ae86 aswell. it's all writen in the post on the front page.

going to be putting 4age into my ke70 soon (hopefully next weekend). have ae71 pedal box,crossmembers comin. just have a question for some people who have done it before. what sort of fuel systems have you used? is there a suitable external efi fuel pump to use without a surge tank or won't they work. trying to do it as cheap as possible. was thinkin of vl style pump. any info would be much appreciated. thanks guys.

Hey mate, the VL pump on its own (no lift pump or surge tank)will work fine, but don't run your tank down too low.

 

I have used just a VL pump in two of my ke70s so far and it works.

[ke70dave]

yep it works....but its not ideal. and it makes a heck of a noise. (i too ran it for a few months, before putting in my surge tank)

 

VL's have a lift pump that works with the high pressure pump, high pressure pumps do not like sucking fuel at all and i belive will eventually fail if asked to suck fuel for too long.

i did this on my car, works brilliantly.

[mrduke]

what i've done that i hope will work is basically what you've done with that lift pump but i've used an intank pump from bout 93ish corolla. had the pump layin round so if it works it's cost me nothin. :yes:

4AGE into RWD KE70 / AE71 / *E7* Conversion Notes

 

Hey All.

 

There's not a day that goes by, when someone ask's *How do i put a 4age into an *e7* !

 

Basically, i keep pm'ing people about it and kindly showing them where to go, but its getting a bit rediculious. So, here i present to you all the links i know off, that can help you out with your conversion. Its almost a copy from the same thing i made at rollaclub, but more things have poped up since. So, its a revised list as such. Please read it, because there is **alot** of data in there.

 

Basically from now on, any topics *how do i install a 4age into my.. etc* will be trashed, and a PM sent to the member with a link to this page. Please remember, IF you do have a technical question or a specific thing your stuck on; we will happily help you out. Its not so much we don't like trying to help people, Generally i know for one i don't want to go to www.ke70.com - technical and see 20 different 4age into ke70 topics, that all really have what this 1 page has on it, as a general starter type guide...

 

Over the Internet, there are sooo many threads that tell people how to put a 4age into a Ae86 / Ke70 / Ae71 - they are all pretty much the same in theory. Sure, theres heaps of different 4age's over the ages, different rib'd blocks, heads, even displacements as well as bolt on's to make it no longer N/A, but its all the SMALL details that make the BIG difference. This is where a sharp eye, and brain cells come in handy. For all of you metho lovers, you'll need some concentration and focus on this topic, so piss off & get help.

 

So, now we have covered that, be prepared to spend anything from $3000 upto $10,000, depending on what you want, the quality you want, and how you want it done.

 

Before you go ANY further, answer these few questions for your self....

 

1) WHY do you want a 4age into your Ke70 / Ae71 ?

2) What is the car going to be used for ? - Street or off road

3) Legalities involved in your state

4) Budget you have

5) how much experience you have

 

After you have put some brain splatter onto paper for those 5 questions, keep reading down...

 

First up, Read all of what i have to post, seriously, then come back with what you don't know, and we can help fill in the blanks.

8) Rollaclub Toyota Info - Everything from A motor rleated to K motor related

- IRallys Ae71 - the car is no longer around, but its memory lives on. This dude knows what hes on about

- Jasons Ae71 Project - again, another great example - check for his updated car on rollaclub somewhere

- and finally, the conversion I'm doing with a friend, 4AGZE into Ae71 ! yes I'm still learning, but i like to research first :lol:

- Mumblez's 4age into his Ke70

- Turbo Rollers 4age into his Ke70

- Trav's 20V into his Ae71
