WELCOME TO THE FORUM!!

Z24The Z24 is a 2.4 L (2389 cc) engine produced from 1983 through August 1989. A fuel injected version was produced starting in April 1985. It produces 103 hp (77 kW).

Applications:

Datsun Truck Nissan Hardbody Truck Nissan Pathfinder Nissan Van Note: All Z20, Z22 and Z24 engines were known as NAPS-Z (NAPZ or NAPEZ) engines. NAPS for Nissan Anti-Pollution System. All NAPZ motors had dual sparkplugs per cylinder except the pre-82 versions. However all NAPZ engines sold in California reportedly had dual plug heads regardless of the year.

The fuel injected version referenced above was denoted as the Z24i (Throttle Body Fuel Injection) and was first available in the Nissan Model 720 ST pickup during the 1986 crossover year to the (1986.5) D21 Hardbody and was later replaced by the KA24E engine. Beside fuel injection, a significant change for the Z24i was the addition of an optical crank angle sensor in the distributor rather than a vacuum advance and ignition module. This allowed for more precise engine management for the fuel injection system.

The General Specifications for the Z24 are:

Engine Type: - Inline 4 cylinder 4 Stroke Engine Displacement - 2389 cc (146.8 c.i.) Bore x Stroke:- 89.0 × 96.0 mm (3.50 x 3.78 in) Compression Ratio:- 8.3 : 1

Power Ratings were:

- Z24 -

Years - 1984 - 1986 Power - 103 hp (77 kW) @ 4800 rpm Torque - 134 ft·lbf (182 N·m) @ 2800 rpm

- z24i -

Years - 1986 - 1987 Power - 103 hp (77 kW) @ 4800 rpm Torque - 134 ft·lbf (182 N·m) @ 2800 rpm Years - 1988 - 1989 Power - 106 hp (79 kW) @ 4800 rpm Torque - 137 ft·lbf (186 N·m) @ 2400 rpm

Here is the info on the KA....I don't think you can make them work.

IM NOT GANA LIE THE MORE I LOOK AT TRHE BLOCK THE MOR I THINK IT WILL WORK BUT THE THING IS I HAVEN BOUGHT THE BLOCK YET SO I CANT ACTUALLY TRY IT... IF I DO MY HOME WORK OR IF SOMEONE GIVES ME A SOLID REASON WHY IT WONT WORK WHERE DO YOU THINK I CAN GET A 85 YM BLOCK BECAUSE I REALLY WANT TO GET THIS PROJECT GOING...

[PEZi]

well i dunno if it will work for sure but i'm wondering the same thing... i plan on doing the opposite of you and putting a 90's head on my 85 block... this will be after i do pistons so that i won't destroy the head!

[dsmboi_ebay]

NOW SEE SO IT BOLTS UP AND THE CHAIN WORKS BUT THE PISTONS DONT CLEAR OR WHAT???? JUST TRYING TO UNDERSTAN WHAT YOU MEAN BY..... "THIS WILL BE AFTER I DO PISTONS SO THAT I WON'T DESTROY THE HEAD!"

[PEZi]

i'm doing high compression pistons and the z24 head won't hold the power... everything should clear fine

[dsmboi_ebay]

SO... BY THE WAY IT SOUNDS IF I KEEP THE 90 MODEL BLOCK STOCK THE HEAD WILL BOLT ON BUT I DID THINK THERE WAS A DIFFERENCE IN THE DISTRIBUTER BOLT DOWN..... IS THERE???? I NEED TO LOOK AT THAT BLOCK AGAIN I GUESS... BUT IF YOU KNOW THE ANSWER LET ME KNOW I WONT BE ABLE TO LOOK AT THE BLOCK TILL THIS WEEKEND.

have you noticed mine?

i did it all flat black including tails corners and signals

[breadbox]

wouldn't a truck from 1990 be a D21 with KA24e?

[dsmboi_ebay]

BREAD BOX- SEE IM A NOOB WHEN IT COMES TO THIS I KNOW THE 90 IS FUEL INJUCTED AND ALL THAT BUT SEE IT IS ONLY THE BLOCK AND THE BLOCK ALONE I NEED AND MY HEAD FROM MY 85 WILL GO ON IT BUT... IM NOT SHURE ABOUT THE DISTRIBUTER AND OIL PUMP SITUATION...

PEZI303- I HAD SEEN YOURS MINE IS JUST A SINGLE CAB THOUGH AND I LOWERED MINE MUCH LIKE YOURS BUT I THINK IM LOWER I HAVE A TOTAL OF -4 INCHES IT IS A LITTLE BUMPY BUT CORNERS AND DRIFTS LIKE DREAM... WONDERING HOW DID YOU FIND THE BLACK CORNERS AND TAILS OR DID YOU DO IT YOURSELF...???

ILOVEMYMINI- THANX FOR THE LINKS ON MOTOR SHOPS AND TEK HELP IV SEEN THE SPECS AND I BELIEVE THE MOTOR BLOCK WILL WORK BUT IM STILL WORRIED THAT THE DISTRIBUTER AND OILPUMP IS DIFFERENT... BUT I WISH YOU DIDNT NEED YOUR BLOCK I WOULD SO BUY IT FROM YOU

YOU WERE TALKING ABOUT YOUR OVERHEATING PROBLEM SEE MINE WAS A BELT BROKE ON A ONE HR TRIP I DIDNT HEAR THE BELT BRAKE AND THAT BELT RUNS MY ALTANATOR & WATERPUMP SO WHEN THE BATTERY DIED IT DIDNT MOVE THE TEMP GAUDGE SO I NEVER KNEW WHAT WAS GOING ON TILL THE TRUCK DIED... WHEN I FOUND OUT THAT THE HEAD WAS WORPED I HAD IT FIXED AND PUT IT ALL BACK TOGETHER HOPING THAT WAS ALL TO MY PROBLEMS WHEN I ADDED WATER TO THE RADIATOR I HURD GURGLING THROUGH THE INTAKE I ROLED THE MOTOR OVER WITH NO PLUGS IN IT AND IT SHOT WATER OUT THE CYLENDERS BASICALLY TELLING ME THE BLOCK IS CRACKED... SO IF YOUR GANA DO THE MOTOR MIGHT AS WELL HAVE THE BLOCK CHECKED SO YOU DONT END UP LIKE ME...

[breadbox]

Well if you grab the harness and ecu too. Wire that sucker up. KA24e's are surprisingly fun motors.

yep... i've heard as long as it bolts up properly its much more suitable for the extra power i'll make!

[breadbox]

DSM"boy"_ebay

I have been driving my old GS-t lately, gave it to mom but driving it til I do my motor swap. Are you a DSM kinda guy?

[dsmboi_ebay]

[dsmboi_ebay]

so pezi303 if a 90 bolts onto a 85 then an 85 should bolt onto a 90.....

[PEZi]

yes indeed... i'm just not 100% sure it does bolt up... i've only heard one person say it will but none that say it won't

[dsmboi_ebay]

the only thing is the block to transmission and block to mounts.... but im so proud this conversation has given us all knowlage lol..... every one let me know if you can find out about the mounts and transmission if they line up ???? its a Z24 transmission and a k20 block..... let me know

[dsmboi_ebay]

OKAY SO FAR EVERY ONE WE HAVE FOUND OUT THAT THE Z24 HEAD WILL FIT ON A KA20 BLOCK BUY.... THE BLOCK WILL NOT BOLT UP TO A STOCK 720 PICKUP transmission ALSOW THE MOTOR MOUNTS WONT LINE UP THE MOTOR MOUNT ISSUE CAN BE FIC BUY JUS SIMPLI WELDING THE NEW ONES DOWN BUT IF YOU WANA DO THIS SWAP YOUR GANA NEED A transmission SO I WANT EVERYONE TO KNOW IM KEEPING THE Z24 FOR NOW AND I REALLY REALLY NEED A Z24 BLOCK PLEASE DO ALL U CAN TO HELP I NEED THIS TRUCK BACK ON THE ROAD AND OFF THE JACK STANDS.....

[breadbox]

just so we are clear it is a z24 block and a ka24e block that are almost the same.

KA20 doesn't exist. K20 is rsx motor.

I got the GSt in trade for my 99civic SI. Found out later that it has a 6bolt swap, so no crankwalk for me. Not sure what turbo is on it, but I hate it. I know nothing bout dsms, Always like the way eclipses looked.

Open the local phone book and see if there is one in a yard near you. These trucks got abused alot so you might find one.

[dsmboi_ebay]

yes everyone major in the ka20 my bas and typo its supposed ka24 lawl

[dsmboi_ebay]

evaryone post pics of there 720 trucks i wana see what the compitition looks like!!!
