A33 Engine Upgrade

[twinhope88]

hi Weikee,

a full tank of 63-liter can run for 720km is marvelous.

My vq20de pumped in 50-liter can only run for 470km max in highway.

it seems 3.0L really more fuel economy + powerful than 2.0L, the bad thing is the expensive roadtax.

I think fitting engine from Z33 and G35 will create a lot of headache as most of the mounting, wiring, etc may be different instead of direct swap.

Anyway, i am wondering if any bro here install a supercharger on their cefiro?

 

[weikee]

Ultimate Cefiro, the local 3L is about 200hp only, the JDM is the one with higher hp and torque and come with LSD g.box :) that is the one in my engine bay now :)

Wow, 20k for the suspension only, dam that is expensive.


twinhope88, don't try to convert rwd 1/2 cut to fwd car especially if you want to use back the wiring. Maybe engine yes, but you will have lots of headache on the g.box and lots of other small small things.

For supercharger think i saw someone was trying to order one from AU or was it NZ. the supercharger kit was develop by some company in US, now is EOL.

twinhope88: yup, i agree with Weikee, very hard to do swapping btw FF and FR since different layout, alotta things also different. But if you want to bolt on turbo or supercharger, firstly our engine is high compression, I had a friend who bolt on turbo for NA cars w/o changing the compression. The result, more powerful than low compression turbo. But the engine wont last too long depends on how frequent you drive the car and the way you step on the pedal. Also, our piston is not as durable as a turbo piston therefore shorter engine life.

Turbo vs Superchrger -- Gd comparison, for me, i will rather choose turbo more than supercharger. Supercharger has a very good response of revving as the supercharger already working since engine idling, which is driven by belt, also reduce air pollution not like turbo which is driven by exhaust gas flow, thats why for now more and more car and also performance workshop i.e. HKS launch a series of supercharger kit for present cars. But the maintenance is a factor, compressor oil also very expensive. If you have to replace the faulty supercharger, it will cost you a bomb as supercharger is usually more expensive than turbine. I.e. the mercedes kompressor for 200K, try to ask the dealer how much is it and you will know, keke. Also, hard to adjust the boost i.e. have to change the pulley to adjust since it is belt driven. Turbo boost can be adjusted by valve system i.e. EVC (Electronic Valve Controller), which provides ease of adjustment. Low maintenance cost as well. Also, the turbine is cheaper and more than supercharger in the market especially in chop shop. Thats why Im going for turbo.

Weikee: above points is just my lima sen, bro, no offense :D

for my ceffy, I had replace my battery to my rear boot, letting more space for the turbine and piping. But as stated, very headache since the piston size between these engines vary eventhough it bear the same series... DET piston is bigger (93mm) than DE (90mm)... and of course the stroke for DET is shorter.....so no choice to swap the piston into DE. also dunno whether the block is fit or not.... headache!! headache!!

weikee: i think 190hp for MEVI is on wheel right?? as stated here

http://wiki.maximasdownunder.org/doku.php?id=mevi_swap

 

[weikee]

UC,

i agree with your 5 cents :D, supercharger is more for low to mid power, and easy installation for Fatty a32 :)

As for the JDM, last time i check it was about 210hp, should not be on wheels lah, on wheels with 190 is dam good already for a auto box

 

[imperialrealcs]

guys, anyone came across VQ25DD engine?
im planning to fit them into my A33 cefiro coz 3L roadtax is juz overkill for me :(

most of a33 h/cut is neo DD engine

 

[imperialrealcs]

but i hardly see them in kl chopshop.. any recommendation?

i hardly c them in kl chop shop, any recommendation?

 

[seizai]

many in northern

price also scary

 

[imperialrealcs]

ah, too bad im in kl.. any sifu can recommend place?
btw, how price scarry is scarry? 10k?

 

[Ultimate Cefiro]

check the motor trader, there should have one dunno sell edi or not.... but the price will kill u also i think~~for that price of h/cut and conversion, u can pay few years roadtax b4 u sell car i think....

---------- Post added at 09:44 PM ---------- Previous post was at 09:43 PM ----------

not that scary i think, maybe h/cut around 7k gua........ just estimate.... dunno actual price....

---------- Post added at 09:44 PM ---------- Previous post was at 09:44 PM ----------

for instance if RM10k include conversion, u may pay 5 years roadtax edi....

---------- Post added at 09:46 PM ---------- Previous post was at 09:44 PM ----------

since it was stated in the motor trader, they have VQ25DD and RBs, price start from RM6.xk.....

 

[weikee]

yeah, not to mention the other things you need to consider when you convert the engine, minimal is about 10k, and that is about 9 years of roadtax after you contra the 2.5L roadtax (about 900+-)

---------- Post added at 01:01 AM ---------- Previous post was at 01:00 AM ----------

if you really want the 2.5L 1/2 cut, can ask chop shop here to source for you, just got to pay deposit loh. sometime when you are lucky you can get some with very low mileage.

 

[twinhope88]

You can order from the chop shop and tell them you only want low mileage car.
i checked with some chop shop, they said the whole front cut is around rm5k + conversion and jpj, etc - another rm3-4k. So total around rm9k.

for a 3.0L, rm9k can paid almost 5-year roadtax, if we are not using the car for the next 5-year then i think it is not justifiable to convert from 3.0L to 2.5L.
Who knows maybe few years later car exceed certain years with roadtax reduction.....maybe....

 

[weikee]

9k is on the low side, you need to consider the oil seals for the engine and g.box, and all other parts (advice to change) cause once the engine is out, is much more easy to do.

10k to 12k is on the comfortable end.

9k can pay for nearly 8years of roadtax lah, you need to contra 2.5L road tax. 2.5L is about RM 900

 

[seizai]

convert ngv much cheaper

 

[weikee]

i got some feedback from a cab driver he always drive me to klia, the ngv conversion for cefiro, and the sentra are not very reliable. but i can't verify this with other fatty driver, since he is the only person i know drive fatty that using ngv.

 

[twinhope88]

then better change the entire car to 3.0L which is much more cheaper and still original (not a modified car).

 

[seizai]

ngv make engine hotter.

especially alu type

 

[twinhope88]

weikee,

why your a32 3.0L FC so low?
many 3.0L run at rm0.30-rm0.40/km.

 

[weikee]

highway driving is always low due to the final drive of the at box. for city driving is the killing, but i have reduce my monthly mileage from 3000km to about 2000km now.

 

[twinhope88]

Weikee, what is lsd gearbox you have been mentioning?

---------- Post added at 04:14 PM ---------- Previous post was at 04:04 PM ----------

Weikee, you said the Japanese version of vq30de is much more powerful, from wikipedia there is 2 versions: vq30de (ingle runner intake manifold) and vq30de-k (dual-runner intake manifold for better high-end performance) - http://en.wikipedia.org/wiki/Nissan_VQ_engine

i think yours one might be the K-version.
by the way, what do you mean by LSD gearbox?

---------- Post added at 04:16 PM ---------- Previous post was at 04:14 PM ----------

in this web: http://forums.maxima.org/4th-generation-maxima-1995-1999/119480-what-vq30dd.html, someone commented:
"You'd have to change the quality of fuel your country uses. The fuel in the U.S. is too sulfur-rich in content for use with direct injection."

is this the reason behind the Neo-DI not introduce in this region? - our petrol grade is not good i think, so have to use the old DE-engine.

 

[weikee]

LSD aka limited slip differential

the JDM version is not the DE-K, is also normal VQ30DE. There are many way to increase the power of a engine. Timing, Cam profiles, compression, ecu. I am not sure what the diff between the MY and JP in term of engine or ecu. But I know is higher hp

Hmm, all A33 VQxxDD is Neo engine mah, and DI is direct fuel injection mah.

 

[seizai]

NEO engine normally hv DI

lsd gearbox is depand on luck

mine dun hv :(

 

[twinhope88]

Weikee: u mean all JP A33 are having VQxxDD Neo-DI? then any half cut is with the new Neo-DI lo.
by the way, what is the advantage of LSD? - increase power?

---------- Post added at 12:24 PM ---------- Previous post was at 12:23 PM ----------

any idea which chop shop accept credit card and allow 0% instalment for an engine swap...hehe....else have to pay cash in full....

i hope during this economy crisis, the JP car is lower....

 

[imperialrealcs]

waaa, change to 2.5L so expensive.. i thought only those 4G92 MIVEC or B16 series halfcut only such expensive.. tak sangka VQ25DD is comparable in price :(
i thought these "cold" engine is cheaper de? why toyota halfcut so cheap?

 

[twinhope88]

i heard mitsubishi half cut is expensive due to heavy demand from proton users.
for nissan maybe the chop shop does not bring in more, so people tend to grab for it....

by the way, if upgrade to 2.5L, then can i sell off my vq20de?
how much do you think i can sell it for?
