My 4k-c Suzuki Sierra And Sold Zze122 Rolla

[Rollasrus]

Hi guys, new to the forum although been browsing on here heaps as a guest.

Mainly on here for technical stuff regarding the 4kc motor in the suzuki sierra I bought recently.

Have owned many toyotas before 2 surfs, an ae82 rolla and a zze 122 rolla, current ly own the rolla engined zook and a 6 inch lifted jeep cherokee, but the sierra and 4kc are much more fun to drive and easier and cheaper to work on. Also the driver trainer of the suzuki 4wd club of nsw.

Here is some pics of my zze122 rolla thats gone and my 4k-c sierra, enjoy

Hey mate

 

Welcome aboard :bash:

 

Do you have any build pics of the sierra? I have a LWB zook with a dead engine I was toying with the idea of shoving a 4k into, would love to find out whats involved in doing the convo...

 

Cheers

Cheers guys

I bought the zook with the engine conversion already done and engineered.

From my experience within the suzuki 4wd club a 4k conversion was the gun thing to do with early 1 litre sierras and the earlier suzuki LJ's untill the 1.3 sierras and the vitara 1.6 engine came along.

 

The 4kc I have was out of a ke70 with the t-50 5 speed box. Obviously new chasis mounting points need to be made up for the engine and gearbox, because I have the later gearbox the gear shifter hole was moved back a little (although I think the earlier boxes with a more forward mounted shifter may not need this) and the slip yoke out of the box remains but goes to a single uni and the standard transferr case input flange (its a tight fitt cause the box is a bit longer) and my transferr case was moved forward about 1 inch. The clutch cable i replaced recently came from a 1 litre sierra and fitts well as a 1.3 sierra cable is 2 inches too long.

Oh and to make the car run on angles offroad throw the corolla carby out the window and get yourself a sierra 1.3 carby. its an aisin carby like the rolla one, the throttle cable goes straight onto it and it is a straight bolt in onto the corolla manifold. I reckon this is necessary as any little step offroad makes the rolla carby cough and splutter, Once I tore 2 transferr case mounts trying to keep it from stalling by keeping the revs up and bouncing it a bit much. the next week went back with the sierra carb and idled straight up easily.

Everything else on my car is all suzuki sierra, it did start life as a 1 litre narrow track hardtop but has been chopped into a ute with a spring over diff conversion, 31 inch tires (standard is 26) and wide track (4 inches wider) diffs and transferr case off a later model 1.3, oh and the later plastic 1.3 grille :S :D

You have a long wheelbase? is it a 1 litre 1.3 or the very very rare 1.3 wide track?

If its a 1.3 lwb sierra i would recommend putting in the 1.6 vitara motor (either carby of efi) much easier to do. if its a 1 litre then any conversion takes just as much work and I know a 4k conversion is much much cheaper to buy.

Good luck with it.

I just have a banged up old 1 litre lwb... its only a farm and fun hack, but I figured since I have all these bloody 4k's lying around... :S

 

Mounts would be no probs... my concern was the whole output/uni/tcase arrangement.

 

May just go ahead with with it then.... Thanks heaps for all that info!

[Rollasrus]

A lwb sierra is treated like gold by any member of the suzuki 4wd club, they are getting rarer and rarer and more desirable than any shorty sierra.

They have a heap more room and are heaps more stable offroad than a shorty and a 4k seems to work better than most people expect, especially as they are cheap as chips.(bought my new 4kc for my zook off ebay for 80 bucks.)

[Rollasrus]

Got a new 4k ready to put into it soon cause the old one is very smokey. Then getting some suzuki sierra 5.38 diffs to lower my current 3.7 ratio a bit so it doesnt die on big hills with the much larger tires and so Low range is much lower when crawling over the fun stuff.

Should hopefully have it done for the rolla cruise to wisemans ferry next month

T50 gear box hey.. don't have an under car pic?

 

Also the Bell housing don't know where the original owner got that from do you?

[Rollasrus]

Sorry mate, I did typo in an earlier thread, its not a t50 box, just a k50. Till I got on this forum I didnt know they were any different

Its a k50 box but with the shifter right at the back, so i assume its from a ke70 or 55

[Rollasrus]

Just bought the whole kitt to convert the 4kc to a 4ke motor from Falkenke30 off here (thanks mate) came with manifold, throttle body, fuel rail, supra

Should make the sierra idle even if I roll it onto its roof now :|

Although the sierra 1.3 carby was a massive improvement offroad compared to the stock 4k carby, it still is not perfect on the extreme stuff, especially if you stall it then have to restart it.

Hopefully efi will improve this even more, plus more torque down low is great in my application.

Got any pics of the K motor in your engine bay? Did you do the conversion? And did you move the transfer case back at all?

I've just got a Murati LWB and have a 7k sitting here waiting to go in! :|

[Rollasrus]

No I did not do the 4k conversion,i bought it about 18 months ago already like that.

I know from the location of the transfer shifter conpared to the standard zooks that it has been moved back about 1 inch. I am guessing for the spline not to slip out on the front shaft the previous owners got a toyota hilux double cardan front shaft. Although this may not work on your maruti cause i am guessing its a 1 litre one which has smaller flanges on the diffs and transfer which wont fit a toyota front shaft. What some lwb sierra owners do when they do a spring over and/or move transfer back to suit longer box (eg k50 or a vitara box) is they get the rear shaft out of a shorty sierra and put it in the front, or you can get tailshaft spacers so long as you get the bolt holes for narrow track diffs and 1 litre transfer.

Since I owned it the original motor blew a piston ring so I swapped another 4k into it (simpler than changing it back to suzuki motor/box etc), then on a drive that new motor blew a head gasket so I decided to get it rebuilt wiithout pulling the motor itself out which was easier than expected. Now got this 4ke stuff but with a microtech d5 ecu so I gotta find out what each pin on the plug on the ecu does so i can figure out how to wire it up.??? any help or should I just contact microtech for info??

I will put some pics up soon of the motor in the zook from when i did the rebuild, computer crashed recently so I gotta look for my old pics.

[Taz_Rx]

Cool thanks for the info mate.

 

Did you get everything off Dan that you need to make it run? ie all the sensons, elec dizzy etc etc?

If you have, it should really just be a matter of plugging everything back into the ecu, give it some power and eart, time it up and off you go! :|

It's not real hard to get a basic ECU like that running.

[Rollasrus]

Dan delivered to me the 4ke rocker cover, whole manifold which had on it already the throttle body, fuel rail, intake plenum tps,and some sensor on the intake plenum etc but it has those yellow supra injectors (maybe too much flow for N/A motor), and the microtech D5 with the loom.

 

I didnt get any dizzy at all, currently my 4k has a dippondenso points dizzy but with an electronic ignition conversion kit I ordered from pertronix ignitions in the states, has worked a treat. I believe the microtech D5 is a fuel only ecu and all it needs from the ignition system is a tacho signal from the coil, I could be wrong though.

 

I am also curious what fuel pump system to use, I am gonna put a low pressure pump with a low pressure filter off the tank feeding into a surge tank (so its great on steep offroad angles). My question is which high pressure pump should be used from the surge tank to the fuel rail? I was assuming the usual vl pump like almost everybody uses.

 

What i really wanna know is what the pins out of the ecu goes to where so I can wire it up correctly, then I will start installing
