Naza Ria Engine transplant

[3309]

Dear All Sifu here,
Need some help and guidance on my Naza Ria engine transplant.
Currently my stock Naza Ria got a lot of problems.
In my mind there are few options:
1. Nissan VQ25DE
2. Nissan VQ30DE
3. Mitsubishi Twin Turbo 2.5

There are 3 factors that Im looking into consideration:
1. Performance
2. Fuel Consumption
3. Maintenance/spare part cost

Thanks in advance.

JPJ no problem. You need to go to Puspakom 1st.
Normally for the transplant engine, you can't sell the car after that.

1. more power, u will get 280bhp.
2. better FC cos v6 ma.
3. better resale value.
4. got ka-ching ka-ching sound hhee..

to transplant 2.5 cefiro engine costs bout rm10k, 6a13tt about rm14k.
better invest abit more to get 6a13tt.

If I not mistaken VQ25DE and VQ30DE is not V6 engine.
Anyway, what is the advantage of that toyota turbo engine over the 3 engines I stated here?

But the turbo engine more expensive on the maintenance right?
How about the durability?

 

[DanzEterna]

i tot VQ25 & 30 is from cefiro & brougham....both n/a.
didnt know 1jz could fit inside, but its 3.0 rite? or thats 2jz? .....roadtax will be a killer.

 

[3309]

Radhie,
This Toyota Engine also use the timing belt. same as my stock engine. I'm looking for the engine that uses timing chain..less maintenance maa...

 

[l2s_turbo]

VQ25DE and VQ30DE are both v6 engines.. if you able to find VQ30DET that would be great...and coupled together with manual gb.. my mechanic has one lying in his workshop waiting to be transplant into his cefiro... for naza ria, he also done many conversions with VQ25DE/VQ30DE.. he mentioned as long as the engine mounting bracket fabricate nicely it should pass the inspection successfully...

How is the maintenace for VQ30DET?
I heard for VQ30DE, the maintenance is less as the engine is so reliable.
Anyway, do you know how much is the roadtax for 3.0?

Danz,
If 6a13tt compare to VQ25DET, which one is better in term of performance, maintenance and FC?

Maintenance i'm not quite sure.. but roadtax is around RM2050 if i'm not wrong.. if want turbo but lower roadtax i suggest you go for bro danz's idea drop in 6A13TT.. i saw before one in autoshow also.. it's green colour naza ria.. i wonder he still owns the car or not..

JPJ no problem. You need to go to Puspakom 1st.
Normally for the transplant engine, you can't sell the car after that.

bro... why cannot sell ah? becos different brand?

 

[3309]

it is a JPJ regulation. if you put another brand of engine, you can't sell that car anymore until you put back the original brand engine.
Anyway, who know where I can get the 6A13TT, VQ25DET or VQ30DET?
Try Mun Lee already but they only have VQ25DE.

 

[Supra_Fanatics]

1JZ 2.5cc, 2JZ 3.0cc

But why choose to transplant a Naza Ria? I meant is better to get a more
potential car like performance car to mod instead. Much more worth modding.

Just my pov

 

[3309]

The main reason here is my stock engine always give me a problems. And to sell this car, I need to top up another rm20k to the bank.

But I heard 1JZ 2.5cc, 2JZ 3.0cc is using timing belt right? and that will add up maintenance cost.

 

[peeche]

all those engine above does consume more fuel than standart engine. Trust me.

6a13 will consume about the same with VQ30DE.
VQ25DE will consume higher FC in town. But about the same on highway. (lack of torque, u can see the figure in wiki)

Maintainance issue.?
Some of VQ owners did complaint they still facing those overheating issue.?

 

[3309]

arrgghhh...how to make a decision

 

[EvolutionZ]

mitsu twin turbo....

All,

As Naza Ria owner with 6A13TT engine for almost 2 years, here what i can comment.

Brought this secondhand Naza Ria because it the most cheapest full size MPV in market (RM50K for 2004) even know so many issue on engine.
Using for 1 year and having teh tarik issue. Repair cost me 5K.
After 1 year again get teh tarik issue again.
This time decide transplant the engine.
Only have 2 choices that time
1) 6A13TT
2) VQ25DE
* refer engine detail below.

Other engine mention on post before like 1jz or 2jz cannot transplant on Naza Ria due it RWD. Naza Ria is FWD.
You need to get FWD or AWD(Lock to FWD) engine.

After so many discussion with friend and mechanic, decide to transplant 6A13TT to my MPV Naza Ria.
Why ?
1) More power.
2) 5 Speed tiptronik gear.
3) Massive torque.

Last time it coast me total RM9K (new part for water pump, belt, half cut, install and JPJ)
But due this is 1st project to my mechanic it took almost 2 month.
The only issue since transplant only broken dry shaft (try sprint 1st gear to 2nd gear) 2 times. Hehehehe.......


After 2 years using it, really like it. No regret.
No issue on engine and wiring except 2 times broken dry shaft (cheap dry shaft. now get the custom made)
Fuel consumption full tank RM120 (RON95) = 400KM(town with heavy foot most of time) & 550KM (highway 110Km/H)
Put blitz blow off. Boost still standard at 0.6
But remember to upgrade the brake system and suspension.

Now planned for big intercooler and twin exhaust system.

Hope this help.

Bro enkei_rs,
Thanks for sharis with us.
I might get the VQ25DET halfcut soon, still waiting the parts from Japan.
But in term of hp & torque, the Mitsu turbo and VQ25DET is almost the same.

Anyway, what type of suspension that you use and how much the cost?
And the braking system, are you changing the rear drum into disc?
