Russel

If I recall, the 3Y and 4 Y are the same blocks, just different bores/strokes increasing the displacement. Therefore it should be a straight swap.

As for the newer 4Y coming with the management, I really doubt it tbh, you'd have to source either an original 1 along with it's harness or buy the after market type with harness.

4Y EFI, is a beaut, I used to run 1 and way better then any carb setup.

Good luck and keep us posted.

Good stuff ,
Guys , Just rechecking prices 4y efi seems overpriced . 2rz /3rz seems competitive .
But would they be worth the trouble .Too much strain on trans/diffs etc . At least i can thrash begazzeas out of 3 y bush bashing my pocket dont hurt .
ps.. Aus is Kool . Will splash photos when cuu cuu kodak system working proper .




ooops Would 2rz /3rz Fit for Starters ??..........lol

Hi Russell,

Rather try to get the Efi intake manifold and Outlet Manifold from a 3Y-E and the Dizzy. Then look at aftermarket Ecu that will run the setup. All more needed,
1. High pressure pump 3bar
2. High pressure fuel filter.
3. Low pressure fuel filter in front of pump
4. Air Flow sensor
5. Idle control valve.
6. Extra temp sensor.
7. Some extra wiring.
8. 2 x 90 degree silicon bends between the airbox and intake manifold.
9. Few fuel hose clamps.
10. Fwe home made brackets for ICV and fuel pump.
11. New Intake&Outlet Manifold gasket.
12. Modify your trottle cable.

Above are just about that I could quickly remember, this setup will give about 76Hp on 31" wheels. For 4x4'ing it is almost better as a diesel at low rpm.

Louis

The 3RZ is the best conversion you can do, enough power, and ultra reliable

You will need: The 3rz bell housing ( fits on your box ), the Radiator and hoses, management system.

The only fabrication will be the 2 brackets between the engine mounts and block

It is well worth the effort

Thanks is interesting option .mmmmmmm :shh: :cool:


Update ordered 4y from china . I insisted on payment using paypal/ escrow only for better protection. Engine company says thats fine . Weeks later found out Order was cancelled by them . My money was refunded but i was disapointed after there promise etc . As site says escrow etc welcome as payment method .
Anyways good news for me , Whilst i would have been thrilled with and ready for a brand new engine . I twisted my cousins arm . He was all for new engine as well lol. We took head off . Very lucky on testing just needed skimming . Ive been concerned for ages perhaps lots damage . Have been running via chemiweld last 2 years .

Now next chapter . Lots life left in this Hilux yet Id love too get hold of one of those vw jetta carbs .

If I had to replace an engine in such a bakkie, I would opt for a Lexus V8 import with a G-box. Total cost of coversion between R2dk-R30k. Lots of torque and power, more economical than the 4 cyl motor.

Must be done by a reputable specialist. I've these conversions on various vehicles and the work great!

Cool! I wouldn't worry too much about the 'ticking' noise .... could just be a hydraulic lifter or perhaps timing chain. If ou were going to have issues, you'd already have had them. ;-)

Hey Russell, My bakkie's 4Y imported engine also had a ticking noise and I have replaced the hydraulic lifters several times to cure the itch, but without it being a success. Don’t know what type of oil you are using in the engine, but a local lube guru advised me to try Total's Quartz 5000 20W50 engine oil and this had fixed the ticking noise.

That is good to know. Have you always used the same oil? I find some oils go black and sticky quicker than others
