Yeah - I average about 11l/100km urban/commuting mainly. Best ive got is <9l/100km worst probably 14 or so. This a gen2 turbo with 3" turbine back exhaust, ebay intercooler, MBC set ~12psi boost. As long as you stay 'off boost' its pretty good on fuel.

I can't see a V6 with a lot more cc will be more frugal than a correctly running 3SGTE.

97 1MZFE Camry uses 11.2L/100KM
95 3SGTE MR2 uses 11.8L/100KM
You'll probably get even better economy from the 1MZFE once it's in the SW20 just due to the fact the Camry is 1400kg and the SW20 is only 1270KG (Even lighter with a 1MZFE in there!). The 1MZFE will run around on cheap 91 all day while the 3SGTE will probably ping it's ass of on anything less then 95 :)
 
I can't see a 3SGTE with a fuel guzzling turbo being more frugal then a correctly running 1MZFE ;)

You may be right Knightrous, but the real world difference between them would be minimal/barely noticeable if at all. I failed to take in account the different mapping too (Jap vs Aussie).

oh, reason i mentioned that is too show the difference the gearbox can make, i'm getting the same or better fuel economy but have to drive 4 wheels and my car weighs and extra 150odd KG.

Just ace - but what if you're not driving on a freeway/HWY? I average about 30 km/h if i'm commuting in peak hour....lucky to get out of 1st. May as well remove 5th to stop it collecting dust.
 
I don't understand why people seem to think that a 6 CYLINDER is more economical. So what its newer and has an econo head but you're having to inject 2 more cylinders not to mention 3.5 litres. Don't want to use family cars as an example, but look what Ford has done with the new Falcon "EcoBoost" - 4 cylinder turbo with great driveability and benchmark economy for such as heavy boat of a car.
 
 
 

lol nah I don't normally use the 2 to commute, only on **** days like today where its raining, 12 degrees. Heater and radio is great haha
Motorbike easily goes thru traffic (its not a BMW tourer LOL), I normally filter through nearly every set of lights :)
the turbos only have a rep for poor fuel economy because of the stock ECU dumping fuel at high revs/boost. I'm lucky to hit 7 pound on the way to work. Don't boost it and the dumping simply doesn't happen.
 
 
 

yer, thinking I'll wait and go a tubby.
 
want one that is stock (may be looking for a while!) as i'll be using it everyday, and not gonna buy now, sell and buy another in about a year. also think there is more of a market for the turbo imports, hard to find many (good) n/a's up for grabs.
 
I agree with a lot that's been posted, v6 conversion would be a nice project, but bigger heavier (?) engine than an I4 turbo, not much difference in power (I think), reliability doesn't increase, fuel is if anything worse, more likely to run into issues seeing as i've never done an engine swap and car would be a daily.
 
also, I'm a rather mild mannered driver (in general), so hopefully turbo wouldn't be spooling all that much (thinking of fuel) but is there in case i need it ;)
 
so IMO, 3sgte > 3sge > v6  (that is, 'more preferred than')
3sgte sounds more fun, 3sge is if you wanna be tight on fuel, but want a midship, v6 is if you want a nice project, something different (why not go v6TT or v8, just chop out your boot! lol)
 
should make a thread comparing 3sgte vs SR20DET, actually surprised that all the silvia fans think so highly of this engine, thought they'd be more biased...

That's a big can of worms. You won't find any clean winner IMO. All the 4banger turbos have weaknesses. On the extreme end, you'll find a lot of mucking around with all. But for 3S pride, the Japs always give them respect.

All have some bottom end weakness, most except 3S have cylinder head issues. All lift heads with massive power/boost. VE of the heads can't really be compared cos there's so many variants. Poor intercooling usually hurts the 3S output. IMO, the 3S is the most robust. Those I've seen with high mileage & known history still get the job done & last. Non interference engine unlike the others & no lifter problems etc. Aftermarket support is weak though, but at least block & crank upgrades come from cheaper Toyotas. Unlike with SR20's where you go custom or aftermarket.
