2JZ vs 1UZ vs 2KD

[AM Racing]

Hi guys, I would like some input regarding these two motors as I am currently toy-ing with the idea of putting one of these two engines in my D4D. Here are some stats:

2.5 D4D 75kw/260Nm
2JZ vvti 206kw/451Nm (wiki)
1UZ vvti 216kw/406Nm (wiki)

Now I have read the debates regarding petrol turbo's and 4x4ing. Some of the points raised:
-Wheel spin coming onto boost while negotiating obstacles
-Ploughing up the country side
-Damaging drivetrain components
-Insufficient torque off idle

Now my logic is this:
-My 2.5 is dead
-I have negotiated some hectic stuff (rocks, mud and sand) with this lack of horses and it faired ok
-At 7,5km/lt it is not light
-0-100km/h 3days
-0-80km/h towing 2 weeks with no stops

You get where I'm coming from.....

Now I'm leaning toward the 2JZ for the following reasons:
-Smaller capacity engine will give better fuel consumption
-Being turbo'd there possibilties for big power with these engines
-If an aftermarket ecu is used then the use of launch control for big torque off the mark is possible

I will be towing a caravan occasionally so I need some power. With the current price of diesel and the higher costs associated with diesel servicing and repairs the petrol route is becoming all the more tempting

Whilst the rumble of the V8 is awesome the screaming 6 is something to behold :evil: :evil:

As jy 2JZGTE vvti gaan moet jy std ecu gebruik, eenvoudige rede die ecu beheer die sequental turbo,s dis n heeltemal ander bestuur styl as dit kom by 4x4, maar ongelooflike krag en jy kan dit beheer om te crawl omrede die eerste turbo vroeg inskop.

As jy 1UZFE vvti gaan net so goeie ombouing nuwe tegnologie ens, maar jou voertuig is heeltemal throttle by wire, hoekom kry jy nie n 3UZFE nie hy is ook heeltemal throttle by wire. Ek sou die auto gebruik. Hou in gedagte dat jy n petrol model se tenk moet kry vir die high presure petrol pomp ens.

Die 2JZ is n langer enjin so dis n stywe passing, jy sal nie n visco fan kan op sit nie maar wel met die 1UZFE sal jy kan ,dis n voordeel vir beter verkoeling as sou swaar sleep ens. Maar ek is ook al gemeet op my Fortuner daar is baie meer spasie onder die bonnet het as die SFA bakkie .My uitkyk is gaan so groot as moontlik wat jou sak pas. Groete

Ek's geen kenner nie, maar vir my is die 2JZ-GE 'n goeie opsie. Hy pas lekker in 'n SFA in, so daar hoort nie probleme te wees met die Vigo nie
Ek's versigtig vir die V8; die ding het hopeloos te veel krag en soos ek aflei op die forum, is daar heelwat modifikasies in vergelyking met die 2JZ :problem:

Sal self graag meer wil weet...

But why???

Sell the 2.5 and buy a V6 Vigo - no teething problems, no waiting time, no broken gearboxes, etc.

And IF you need more power, fit a TRD supercharger!

[PERS KERS]

Vir die geld om n V6 Vigo te koop en dan later n TRD charger op te sit is dit beter om die bakkie te hou en 3UZFE in te sit . Ek het die som gemaak om my Fortuner te supercharged- 3UZFE volgens my beter opsie.

I will do some more research on how each engine makes its power. I would prefer the manual gearbox option. Alex, where would I be able tp get my hands on an original ecu for either motor including the wiring loom?

Dylan look at http://www.enginesandmore.co.za/ you can buy a complete front cut then you have the engine and all the electronics you need.

[PERS KERS]

2JZGTE en 1UZFE vvti het ek ecu's, op die V8 moet jy ook nog airflow meters soek. Enjins & more het geen voorraad op V8's nie. As jy die enjin koop moet die harness nie gesny wees nie verder is dit baie maklik vir ons om hom aan die gang te kry as alles daar is . groete

So I've taken the plunge and ordered a 1UZFE with the OEM ecu and wiring. So hopefully it will be here next week so I can get the rest going. I am looking for the following:

1. Flywheel
2. Bellhousing to suit my gearbox
3. Clutch kit: I will source local on this

Next question: I have the thicker D4D radiator in and its brand new. Would those of you who have played with the 1UZ know if this radiator has sufficient cooling capacity for this motor?

And very soon I will have a 2KD for sale....

[PERS KERS]

Dylan ek stel belang in jou petrol pedaal "in jou geval diesel" jy gaan hom nie gebruik op daai 1UZFE nie laat weet. groete

[AM Racing]

Sal jou laat weet. Wie is die beste vir die bellhousing en flywheel?

[PERS KERS]

Fana sal ek aanbeveel in pta

[Kaspaas]

Dylan, ek gaan "meskien" belangstel in jou 2KD.
Laat weet maar as daai tyd naby is.

When are you going to start?
