that being said, i'd be happy to give any 5 litre a run....
If it was a totally free conversion, and fuel usage was the same, I would swap my alloytec for a 5l, I might loose, but loosing whilst sounding good, yes please :beer chug: haha
a v8 .......
The good old buick....
+1 for buick hahahaha lol but yea ecotec all the way ???alloy tec are poo
-1 for buick hahaha
Got an Alloytec 175 in the VZ ute, never mised a beat after 130,000kms, getting 7.9L/100 on the highway. Runs very smoothly and I would recommend it t anyone looking for a V6 large car.
Even though the power down low is a bit off, there is no doubt that above 3,000rpm it howls like crazy (especially with the 2 hole mod and race filter).
lol, big dirty great single peggers, don't think that counts as 'sets'... I think you give the old 3.8 more credit than it deserves, until you go FI these motors aren't that great a system. Still better than Emotec and Alloytec though.
I think some of these guys are smoking 1st and 2nd on VN's are still running those tyres from 1988
LOL 14" wheels on a s1 VN are lethal but still good enough for a 6.8sec 0-60 with LSD
i say the alloytec would be the newer and better motor anthough it hant realy had the time to show its faults like the 1995 ecotec. because of the ecotec being in a lighter car id preffer to drive a vs over a vz any day.
i haven't seen it before and found it an amusing read
I. Care. --.--
no supprise the ecotec has more votes only because its been in more cars, but the alloytec is alot better in terms of performance and economy.
ecotec cause i've done over 400 passes over the 1/4 on a stock bottom end
dont wanna know what you do with your cars. my ecotech hasnt put a drop of oil on the ground in the 6 1/2 years its been in the family
I've had heaps of ecotecs and two alloytechs. The performance is a LOT better in the alloytech, smoother, stiffer, more off the throttle but once it gets to the higher top speed, it's shocking. Dragged my mates ecotec and at the top speed he was pulling away like nothig
As for reliability ecotech for sure! I've heard nothing but bad things come from alloytech when it comes to the timing chain once it hits 200thou. Whereas an ecotech will go to 300, 400 with good maintainence.
Plus the alloytech is a bitch to work on.. No room, hassle just to change the plugs. It's a 2 hour job just to take the plugs out! The ontop of that, you have to replace the gasket and all sorts of ****!
Ecotech is definitley the better engine
I traded to a VZ SV6 , from a VX Equipe , that had the following mods - SS Growler intake , 12mm plenum spacer , 12mm manifold insulator , 69mm throttle body with tune , high ratio rockers , extractors , and 2.5inch exhaust , and have to say the VZ has it beaten hugely in terms of power, preformance, and smoothness .
I think the Alloytec gets a bit of an unfair rap from some people .
Which gearbox does your VZ run?
TBH, I don't think the alloytec engines were a huge step up in performance, just have a look at how much extra torque it makes over the ecotec (and then look at how much extra torque that made over the Buick 3800V6....), the difference is only that it spins faster (320Nm, 304Nm, 292Nm). Torque X rpm = power. By simply spinning the engine faster you can make more power even if your not really making any more torque. I think the biggest difference was the improvement in gearbox options. The standard fare 4L60e box is Ok but it's not fantastic as a performance orientated gearbox as the ratio's are just to wide. 5 and 6 speed automatics are going to eat a 4 speed even if they have the exact same power.
They do have more easy potential though with multi-over heads cams etc.....
It's got the high output 190 Alloytec which I realise is night and day compared to the Ecotec ,it's got the 5 speed auto as well , only mod ( so far ) is a Mace CAI .
