Transplant to VQ25DD from A33

[12savefuel]

Original is using an NGK 6 so I would go with VK20 which is denso equivalent. You can use VK16 which is an NGK 5 but I think its too hot a plug and will cause high rpm and high load detonation. Its ok for normal city town driving. When i use NGK/denso 20 heat range the plug looks just nice, NGK5/denso16 the look of the plug is clean but a bit white and hot on the ground electrode.

hi guys, sorry for bringing up old thread.. seems like my VQ30DE finally dead and its time for VQ25DD. i would like to confirm few things before hand,
- can the engine use RON95 nicely?
- issit possible for me to use back original meter instead of 180km/h limited meter from japan halfcut?
- What is the best spark plug for this VQ25DD engine? need for maximum fuel economy.
- do u think i should port the emanage blue to this car?
- is the GDI system always giving out problems?

thanks for the patients! i need to watch my budget, therefore i have to confirm everything before actual work :(
is there owner of VQ25DD in here? your thought are most welcomed!

VQ is best to use 97. Even 2.5

ic but i can use emanage to tune it to run on ron95 rite? despite there might be some powerloss?

You still are doing timing retard, anyway is still lost of power. How effective, i am not sure.

I only can tell you when i pump 95 into my fatty 3L, my wife can tell the difference when she drive.

omg guys. i just did the transplant from VQ30DE to VQ25DD and apparently my foreman messed up the whole wiring of my car! these are among the problem spotted:


1. CEL on
2. Seatbelt signal always on
3. Airbag signal keep on blinking
4. no 4th gear!
5. gear shift sometimes slip
6. rpm super low around 600rpm. if D without pressing throttle at slope the car will roll down
7. OD, 2, L all useless
8. when traffic jam, press the throttle will have jerk abit then only the car move.
9. bumper lower than usual. car confirm accident free!
10. aircond only cold at 18.C if set even 18.5 or 19.C, then only hot air coming out...
11. sometimes turn on headlight will trigger horn
12. hid level not adjustable
13. no front sensor
14. rear demister not functional
15. automatic headlight not functional
16. Rear Auto dim mirror not functional
17. Meter light not adjustable

i would really need any contact for experienced foreman that can help me settle this problem. please pm me or sms me at DiGi-2156800, Alan! thanks all!
btw, my car has been stranded for 2months and according to him, the gearbox problem unsolvable and he blame the gearbox rosak. i would seriously need second opinion!

bro imperialcs, serious problem you have there, seems like really need to put the car away for a few more weeks. just hope that no serious electrical/electronic problem has occured.

i think you should bring the matter up with consumer tribunal if your foreman doesn't want to compensate for the issues he has brought to your car.

if you are in pj/shah alam/subang area, i can recommend my mechanic over in glenmarie, honest guy, or i can direct you to gt auto also...hehehe...

@@ sound serious...mine everything fine...just the aribeg light not there..but foreman said is function...need to check...mine RPM around 600 when engage to D. I think is normal...low rpm... Meaning u cant kick down at all??

But one thing mine same as ur...mine air con when adjust to 18' is cold like hell, but when goes above 23' ...koyak....ur issue try ask him check whether he connected with the 'In car sensor' or not..that's for the 'auto' temperature...if i'm not mistaken coz i having this before the problem fix.

p/s ur foreman wiring really jia lat...he hv no idea how to convert/modified those wiring.....and for TAN CHONG they cant diagnosis...I'm SA from tan chong i consult them...they cant do anything...

Says "teo of subang" recommend. no guarantee that he can fix your issue though, but no harm getting second opinion, he's been handling my A32 since i go them and transplanted my engine as well.

haha, we all know GT Auto's pricing... will be sending my car there to get the steel braided brake hose done though, trust their quality work compared to normal workshops.

no prob.

i transplanted VQ25DE, but i'm running on A32, not A33, just in case you have not noticed.

for my transplant, no issue at all, except the previous owner did meddle with something and my gearbox selector switch is having some insensitivity issue...

VQ25DE as far as i concern is straight swap unlike VQ25DD :(

 

[whatzzzup]

A32 hv no issue with the wiring...but a33 totally different....

 

[imperialrealcs]

anybody know where can i get this "Fuel Temperature Sensor" for VQ25DD?? i've searched high and low in google and nothing has been fruitful so far!
please help me :(

yes, it's a straight swap, but if can get the half-cut with the proper harness would be better...

A33 has more electronic stuff..
