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.
