gday all just trying to think what to do next on my car getting resprayed in april then i want to save up for a new motor i cant make my mind up between a rb30t or ecotec? which one could i get more power out for less?
Any input would be great
Whipit
Rb for sure but if your looking for a cheap swap id go the ecotec and put some mace gear on it
tuning done by THE1 A+++++ tuner
And powering it by MACE
Build it to handle the MANG
RB30 engine with low Ks. If you cant find one then the ecotec will be best.
Rb30 have more performance parts available then the ecotec.

What he said.
RB30 is old and small. It was marginal in a VL anything heavier and you're shooting yourself in the foot.
3.8ltr at minimum.

I'm pretty sure you can't put an RB30 into a VP, because the engine is older than the VPs

Ok so far i think i will go low ks ecotec if i can get one but rb30 less electrics (i hate wiring)and turbo lol. Ill have a hunt around to see what i can get because i have been looking up both conversions and gunna need the same amount off work either way
Vl commodore RB30ET motor produces 150kw
Ecotec 147kw

Look at the torque.
Also, the RB30 has just as much electrics and will be far harder to put into a VP then an ecotec will.
Ecotech all the way much smoother and i think they are much much easier to install

Hmm dont agree with the first part but second part most definately

ok ecotec it is ill have to get one and get sum macer performance gear
I would go with the ecotec, I mean why would you wanna put an older engine into a newer model car. All you need is a cold air intake system, k&n panel air filter, exhaust, extractors and get a decent upgrade on your throttle body with a good tune your car would be awesome a dream and real pleasure to drive. You can even get a bigger cam and you will have a road eater you will beat all 4 cylinders and if they have turbo then you got turbo as well cya later to them, you will beat somemodern V6's and stock 5.0L V8's. These mods on the buick V6 and ecotec are absolutely dynamite!
Lol
CAI,Exhaust,Extractors,Throotle Body,Tune. Will not beat 5.0L V8 it wont even beat a Honda S2000 and i believe its 4 cylinder.

I lol'd. You're deluded.

LOL mate.... i dont see any 1000+hp ecotecs getting around and i doubt there more than 5 sub 10 sec ecotecs. Yet there are plenty of RB30ET's getting around doing these sort of things.
My money on the rb30 for outright power and potential Conversion isnt really difficult vl k frame and everything bolts up and just as much wiring as an ecotec.

Don't see many people doing much more then bolt on mods to the Ecotec though. LOTS of big dollar builds on RB's though. They're not a cheap engine to make fast.
Donating Member
EDIT should have read it properly
The money you'd fork out on your extractors, exhaust, rockers, cai, intake plenum spacers, Bigger TB, tune and all those other little mods, Is comparable to a RB30ET with exhaust , intercooler more boost and a tune and i know which is is going to be faster.
If you throw in a cam and tune for the Ecotec. Compared to a cam and tune to RB i still think RB would be quicker.
Now if you went all out on the Ecotec and put a turbo kit on it . Then Spend the a comparable amount of money on the RB30ET it would make more power and be more reliable

I'm not totally sure what you're getting at.
Rb30ET is a turbo motor. Ecotec non turbo motor.
You can run more boost on the RB30et motors.
I think if you were to turbo a ecotec you could only run a boost of 10 psi on the factory internals even then your pushing it.
With the mods I said you would get 200+kw throw a turbo and could get possibly 300kw+ put it this way it wouldnt just be any normal everyday commodore anyway. Ive seen it done on a series 3 vs and it did blow away the 5.0L remember the vn 5.0L was only 165kw and the vr ss only 185kw so I think the V6 with the mods would beat it. Also throw in a dog box tuned to the optimum levels and it will beat manual cause no matter what you cant think quicker than the computer.

U guys make it hard to make up my mind lol iff i was going to turbo the ecotec later what internals would need to be changed to withstand 12+ boost?
Donati..Whoa Green
Why not fit an L67 now and just get a smaller pulley. 10psi straight of the bat with no mods other needed. Later go an intercooler and run more boost.
