Hi, i have an Isuzu D-max 2.5 4x2, which is fine in terms of functional & durability.

but the engine power suck till the bottom, which i would rate it as the slowest car i've ever driven, and everytime it makes me looks like a lane-hogging bastard in highway, and sometime, it's extremely dangerous when i need to overtake cars when driving on kampung road.

so, is there anything i can do to make the engine slightly more powerful? any modification i can do or any recommendation on engine transplant?

this version


thx in advance

Remap....change air filter ..bigger intercoller...change whole exhaust

ok, it is not a common rail engine, and not having intercooler, can be done?

Yours is the one which has only 176NM of torque that version ?? If yours is not commonrail, I don't think a remap can solve your problem. If commonrail one, easily 400NM+ of torque can get with a remap.

Can change bigger turbo and intercooler...parts and labour will cost u around 3k...

If iteq2.5 yes...

Better trade in one with iteq 2.5 or 3.0, then can mod easily

Secondhand a lot

maybe u can have a look at this if just wanna eliminate the turbo lag and wanna gain some minor hp and torque...100% plug and play and no wiring cutting at all...simple and steady

yes, the super underpower one

sounds ok, but normally how much power increase?

i was thinking of transplant an iteq 2.5

erm.. what is that?

Expect around 20 to 30hp would be ok, higher will destroy your engine..actually adding only intercooler will increase your hp too- around 10 to 15 hp...but intercooler only will bring turbo lag that why need turbo upgrade too.

hmm.. seems like not much..

any idea how much torque will gain?

i always carry heavy goods & travel long distance, guess torque could be more important..

Perhaps from 176 to 260 tq... but ofcoz if u got more money to spend u can always set it up high with high performance turbo...my advice is, add intercooler only first...turbo later. But if total mod cost u over 6k ...better trade or buy another pickup...

haha.. make sense, probably changing car is the ultimate solution..

if it can increase from stock 176Nm to 260Nm & the cost is around RM 3k, i would be glad to invest on it..

but i'm also having another thinking of transplant to the 2.5 iteq, wondering how much would the cost be..

New or old?
Old one 4x2 dont have turbo iinm..
Power do suck ass if ur going for speed.. Which is what its not designed for..

year 2011, it has turbo but no intercooler, funny thing is i don't see the turbo is doing it's job..

Checkout alphatech, unichip, racechip. maybe they got a solution for u too.

ora sudah got turbo? try google ada racechip for your car model or not.

TD06 turbo , alphatech , larger intercooler , and minor tune , can get around 250 horse power ... but cost around 20-30k ... another suggestion ( change to current isuzu 2.5 VGS 4x2 .. or vcross 3.0 )

This model arrr. No commonrail geh, i have one before. Very slow de. What u can do is adjust the fuel pump to gain little bit power, but i will become more smoke. Don't hope for unichip, EcuShop,bla bla bla... coz it can't tune. And last thing, if u looking for power don't waste money on this engine. Dump in a 1 JZ since you ride only got 2WD.

no need 250hp.. just need the torque, i'm actually checking with 2md hand & new pickup now, considering the dmax 2.5 vgs, triton 2.5 & hilux 2.5 vnt..

yalo, slow like snail.. 1jz? that sounds very interesting..

Ya slow like snail but its a tough work horse for me. Mine is 08 model and i sold it few years ago. 1JZ is the best option for u coz its cheap and reliable.
