There are few buddies asking me "should i turbo charged my engine?"
The answer is might be "Go for it" or "Forget it"
there are also a few fellow are lazy to GOOGLE and do some homework about it and teasing other people when people giving suggestion to go for 1jz.
For me i will go for 1jz for a few reasons.
First of all, it is just depends on you, your budget, and your preference.
For me why i got to 1jz because i cant find any good tuner for 3s motor in my place..
Secondly, why should i spend a lot of money just to get max about 300hp on standard internal when i can go about 450hp-500hp with 1jz standard internal.
Thirdly, Drawback to the BEAMS is the high compression. Adding a turbo will only deficit its longevity.
I am not saying BEAMS engine is not good, there are some 3s motor in US make a lot good of power.
If you would like to have an instant power without not much headache. 1jz is an option for you. Some of you will say you need to have atleast 20k to do it. It may be true or not true. It just depends how much you get the halfcut and how much you pay for the installation.
A few places can install the engine roughly around rm2.5k..
3SGE Beams build up = + turbo kit + metal gasket + management + injectors + intercooler + all the necessary piping will cost at least RM10k... usually up to 25k. Depending what type of turbo and management you use.
1JZ GTE VVTi RM9500 + RM2.5k installation charges = instant power (280hp dude!)
I guess someone will ask later "what about the weight distribution?"
this is one of the disadvantages if you install 1jz inside your altezza because you will no more get 50:50 weight distribution but back to my point up there. I cannot find any good tuners for 3s motor. if somebody know who can tune it..let me know..im also eager to put my old 3s engine inside a KE70. Although 1jz give you heavy in front parts, my car have no problem to be drifted anyways.
So my conclusion is you may choose either. there are pros and cons in both ways!
This is just my opinion and my preference.
