Narcilepsy Posted April 6, 2011 Posted April 6, 2011 Hi guys, my first post so be gentle I seem to see a lot of US 240/260's with the turbo Buick engine, which i believe is the L67 3.8L V6. But i haven't seen any aussie Z's with that setup, is it illegal over here to put that drivetrain in them? TYVM Narc Quote
Sirpent Posted April 6, 2011 Posted April 6, 2011 Correct me if Im wrong, But thats the Commodore motor, and if so Australia is the last GM local thats using it now in production cars. I havnt heard of anyone doing it here yet but it's totally doable. P.S. Welcome John POST Script, yep correct, see following link http://en.wikipedia.org/wiki/Buick_V6_engine Production of the 3800 V6 engine officially ended on Friday, August 22, 2008 when plant 36 was closed. There was a closing ceremony and speakers who extolled the virtues of the engine. Originally GM had set this date for January 1, 1999; however, due to the vast number of complaints from both investors and customers because of the popularity and reliability of the engine, the date was extended. At the end of production, the LZ4 3500 OHV V6 replaced the naturally aspirated 3800 applications, and the LY7 3600 DOHC V6 replaced the supercharged 3800 applications Quote
luvemfast Posted April 6, 2011 Posted April 6, 2011 Welcome. If you want to give it a go, why not it's your choice. Bang for buck? There would be better choices for the amount of work. Quote
zzzzed Posted April 6, 2011 Posted April 6, 2011 I just hate the exhaust not from those engines.. They sound like a fart in a bottle Quote
Sirpent Posted April 6, 2011 Posted April 6, 2011 Found this surfing, be interesting seeing one done with a 200+ kW Com motor. Quote
Narcilepsy Posted April 6, 2011 Author Posted April 6, 2011 Yeah John you're right, they were in the larger Commodores in aus, mainly monaros and HSV's. i know a guy selling a full motor (supercharger/loom etc) + trans for $2k out of his VT HSV, another poster commented on bang for buck (sorry cant remember the name), and as im new to the Z car scene, any chance you could point me in the right direction, motor wise? ty again Narc Quote
d3c0y Posted April 7, 2011 Posted April 7, 2011 In QLD you would have a lot of trouble registering a 3.8L Turbo V6... From my limited knowledge an RB26DETT conversion is pushing it for legal upgrades. Quote
NZeder Posted April 7, 2011 Posted April 7, 2011 I know one of these conversion was done here in NZ a few years back as the car ended up wrecked and a local club member picked up the wreckage and striped it for parts with one of his mates taking the engine out for another hot-rod project (not a zed) Quote
RB30X Posted April 7, 2011 Posted April 7, 2011 There was a 2+2 up here full of rust a while back with a V6 and 5 speed. Apparently went like the clappers in NA form. Quote
nat0_240_chevZ Posted April 8, 2011 Posted April 8, 2011 id personally go a vz or ve 3.6 dohc, aloytec new gen....still 20 years behind any jap motors but.......215+ std kw with a an edit....... speaks for itself.... Quote
Sirpent Posted April 8, 2011 Posted April 8, 2011 Ummmmmmmmmmmmm Oppppppppppppppps Just remembered someting. Drrrrrrrrrrrrrrrrrrrrr, Unless its NA (injected) based on what I'm going through with the AMG charged 3.2L, you wont be able to fit a 3.8L turbo or supercharged motor. Under the classification (In VIC anyhow, which apparently will become a National standard) the max you can go on a forced induction motor in a Zed is just under 3.3L, otherwise a NA Holden V6 will make it easily. There is a guide to the calc's in my build thread around page 20 from memory. Cheers John Quote
Scottz Posted April 8, 2011 Posted April 8, 2011 Interesting some years ago I was looking at a 215cuin V8 alloy for a conversion/upgrade (approx 3.5 L). It was not for a zed. It is one of the most successful engines ever built (as in units made and car models that used it). Light weight and can punch the HP. Originally Buick made but Rover got rights to manufacture midway to late through its life. Unfortunately it was used in some 'ugly' cars, but a nice engine. See link. http://www.britishv8.org/Articles/Rover-Autocar-Article.htm You can stop cringing now Quote
MaygZ Posted April 8, 2011 Posted April 8, 2011 Thanks Scottz, that's a really interesting read. It highlights to me the 'disposable' attitude of the US at the time. Quote
Sirpent Posted April 9, 2011 Posted April 9, 2011 If Im correct this would have been the same motor used in the Triumph Stag's ? If so, they had a wonderful raspy note to them, but the SU set up was useless. Quote
BenZed Posted April 9, 2011 Posted April 9, 2011 Stag was a much smaller V8, 2.5 I think? 3.0 at most Quote
Sirpent Posted April 9, 2011 Posted April 9, 2011 Stag was a much smaller V8, 2.5 I think? 3.0 at most Spot on Ben It was a 3.0L V8, just did some surfing and read that it was developed in house using a Leyland L4 that they combined to produce the motor, original capacity was to be 2.5L with Bosch fuel injection but they had drama's getting it to work so they increased the bore and got it to 3.0L and ended up using Strombergs instead. Quote
NZeder Posted April 9, 2011 Posted April 9, 2011 All this is starting to get off topic above small alloy V8 etc but for the record - the Stag engine was a Triumph engine and not related to the Buick based Rover. This Triumph engine is a bit of a dog which is why even Triumph used the Rover V8 in their TR8's as the Stag V8 was just that bad. The Daimler V8 was 2.5L and was a good little engine - popular in open wheel racing too before the F5000 stated to take over as the open wheeler V8's I have seen a few 3.5 All Alloy Rover V8's insatlled in zed here in NZ over the years. Now I know this thread is about the L67 V6 - but what about a Nissan 350/Maxima or 370z engine between the struts in NA form this should fit within the new VIC repower rules? Quote
BenZed Posted April 9, 2011 Posted April 9, 2011 Agreed, VQ35/37 makes a lot more sense, compact and lightweight and far more advanced design. Did I mention I have a Z33 6-speed box for sale? ahem... Quote
luvemfast Posted April 9, 2011 Posted April 9, 2011 Using the 350Z engine keeps it in the family too. Sounds better than my wifes Commodore to boot! Quote
Sirpent Posted April 9, 2011 Posted April 9, 2011 True about all your comments regarding the Nissan VQ35/37, but I think what he was originally eluding to was that a mate of his had a SC V6 and from an economical point of view this was attractive to him. Quote
