Suggestions on swapping ke70 with 4GR

[hammadshami10]

Assalamualaikum members
I need suggestions on putting
Mark X 2500cc 4GR engine in Ke70

Has anyone done it ?

[Hassan1991]

Wailaikum Assalam.
Some questions before getting into possibilities.
What is your budget?
Any prior experience?
Already got the car?
Purpose of the build?

[hammadshami10]

I've an experienced friend
Have the Car
I wanted to go for 7K / 3S

But There's a 4GR engine in excellent condition and very reasonable price, someone did a swap

Main purpose Drifting

[Hassan1991]

Good, does engine came with it's own wiring and ecu?
Which transmission you are thinking to mount it with and which differential?
Live axles or independent suspension?
@rajaatta

[hammadshami10]

Yes wiring ECU is included , transmission is included as well , mark X automatic transmission

Everything else stock for now ?

[Hassan1991]

Not gonna work.
You need to simulate many sensors output to make it work.
What you need is a standalone management system, Manual transmission and good shaft to wheel ratio.
Better if you can find a 4age.

Hey Hassaan I need to ask a question.. due to current financial crunch I bought a corolla 2007 Altis manual for my home use as no car was coming in this budget.. what I have realized is that it has very short gear ratios despite being 5 speed transmission, can I do something about it.. I drive a 2010 Altis auto it has better ratios , bought this for use at home by multiple drivers at home .. can ratios be altered for top speed cruising or a 6 speed Altis transmission will bolt on to it without any alterations..

[Hassan1991]

Bell housing of 6 speed might match but clutch and flywheel will be different.
Find c150N transmission came in early 1nzfe. Easily available in market. It came with long 3.5 final drive.
Either swap the transmission or final drive.
But remember Ecu has rpm/speed mapping in it to tell in which gear car is. So that will change.

[hammadshami10]

Hassan bhai

Shaft / differential looks like a problem

But why why can't I put auto transmission?

[hammadshami10]

If possible can you share your number ?

FB or something where i can call ?

[Hassan1991]

Not the differential. It's ratio.
You can use automatic transmission but you have to match the differential ratio. Or install the differential of same car. Otherwise your car will be hitting redline at 150km/h.
You can reach me here anytime.

[hammadshami10]

Any idea how much will a mark x differential cost ?

[hammadshami10]

Any other differential in mind ?

Or is it possible to somehow alter and match the ratio ?

What if i change the differential after a while ?

[hammadshami10]

If possible can you please share a video(s) ?
On this ? Transmission/differential gear ratio

I can't find a relevant one

[hammadshami10]

Hassan bhai the problem will be The engine will be running at high RPM and speed will be lower ?

Am I correct ?

Is it okay if I somehow setup with old differential for now and change the differential later ?

Apologies for posting in parts

[rajaatta]

It's a suicidal project.
What is the purpose of the project drift car? Racing car or daily driven car along with drift shashka?

4gr is a mess many have done jz and uz swaps but it's a cofin no brakes misbalanced chassis.
Overweight.

3s is also a risk but it can be handled.

My personal opinion for this vehicle is 7k EFI along with 4.9 or 5.2 diff ratio it will be same like a drift vehicle and also daily driven vehicle too with all shashka he needs like a large engine

[rajaatta]

Old diff will break in 2nd shift the 4gr produces massive amount of torque so not recommended at all

[Hassan1991]

Yes. Chassis will need counter weight to balance that.
4age BT will also be fun.

[drazahussain]

So I need to change ECU along with transmission.. it's 1zzfe, I doubt I will find a manual ECU for it.. difficult undertaking

[Hassan1991]

No idea about the cost.
As mentioned by the member it wouldn't hold the power.
You can search on shaft to wheel ratio. Or differential ratio.
