Muncie Posted October 30 Author Share Posted October 30 Successfully failed WOF because i had a fricken Turbo still fitted..... long story short aliexpress VBands were random diameter so didn't fit manifold or turbo so that sucks. Wof guy happy to see as is no issues with my work just wants some extra heat wrap on crossover pipe and obviously turbo and intercooler absent from engine bay for recheck. Might go buy some Moreys to help nurse through to drag day. 3 Quote Link to comment Share on other sites More sharing options...
zach_munce Posted October 31 Share Posted October 31 Could see if poppa would let u borrow his car for the day Could even put the exhuast on Quote Link to comment Share on other sites More sharing options...
Muncie Posted November 6 Author Share Posted November 6 Thinking ahead to cert time @cletus has anyone used these yet? Pricey but bolt in would save so much pissing around making one. Quote Link to comment Share on other sites More sharing options...
cletus Posted Thursday at 04:00 Share Posted Thursday at 04:00 He does a lot of loops to suit a heap of different cars, I don't remember seeing a commodore with his ones but they're usually OK, I bought one of his universal glue it together yourself kits for my green car 1 Quote Link to comment Share on other sites More sharing options...
Muncie Posted Friday at 08:39 Author Share Posted Friday at 08:39 So......... what does it cost to rebore a v6 out next size? Now ive had a taste of turning the wick up i want more so will start looking at throwing new pistons at my spare supercharged block and getting it in. Im not kidding myself this thing is gonna blow up at some stage. Quote Link to comment Share on other sites More sharing options...
Alfashark Posted Friday at 09:21 Share Posted Friday at 09:21 Is this a 3.8 or the 3.6? Autodelta took the alloytec 3.2 (same core as the 3.6) to over 4L in one of their Alfa 159 projects. Quote Link to comment Share on other sites More sharing options...

Autodelta took the alloytec 3.2 (same core as the 3.6) to over 4L in one of their Alfa 159 projects. Just mean a rebore 20-30 thou over im so old i don't know the metric equivalent. My other block has scored bores it needs new pistons so may as well machine out fit new stock ones open ring gaps up a bit 500hp + on an L67 is apparently no issue all the cool kids in Oz are doing it. It's the 3.8. Alloytecs are a very different beast i bought one and pulled it down decided not to go ahead with it. way to complicated and the stock ECU'S aren't reliable or well supported which would of meant needing a $3k ecu to run it and then the rest of the car would throw a fit. Be very cool though outside my skill set and budget for what I want. 1 Quote Link to comment Share on other sites More sharing options...
Roman Posted Friday at 22:58 Share Posted Friday at 22:58 More displacement will just turn your drivetrain into a noodle by loading it up with low rpm torque. Maybe a little bigger cam, bit more boost will acheive same thing easier? There's so many headaches associated with engine machining work, that can often go wrong even if you get the best people involved. I reckon there's bound to be a sweet spot for you with factoryish block and the right bolt on stuff. Do you have any guesstimates for drag day time / MPH / etc? I think I'll be somewhere in the 14s on first shakedown and with standard cams. (assuming I make it) 3 Quote Link to comment Share on other sites More sharing options...
cletus Posted Saturday at 04:54 Share Posted Saturday at 04:54 A rebore is not going to make much if anything of a power increase on its own The real power increase is the fact you can lean on it harder with non cheese pistons, correct ring gaps etc 4 Quote Link to comment Share on other sites More sharing options...

Nominal Posted Saturday at 07:06 Share Posted Saturday at 07:06 Best next step would be to weld two more cylinders on and fit a V8 crank. 1 Quote Link to comment Share on other sites More sharing options...
mjrstar Posted Saturday at 07:25 Share Posted Saturday at 07:25 Or align 6 cylinders in a row, take capacity out to 4 litres, and add twin cam head with variable cam timing. 5 Quote Link to comment Share on other sites More sharing options...
Muncie Posted Saturday at 10:17 Author Share Posted Saturday at 10:17 Next engine is a simple combo based on the supercharged L67 block it needs a rebore due to some scored bores so new maybe forged pistons and rebore, then run the ecotec heads. Throw some arp hardware at it l67 has good rods already, did think about forged bottom end but I can't afford a 700hp capable drivetrain anyway so why bother. Will use the best of the factory gear for this one and lean on it. 2 Quote Link to comment Share on other sites More sharing options...
Muncie Posted Saturday at 10:32 Author Share Posted Saturday at 10:32 Seems some of ya got wrong end of stick im not building a stroker just a freshened up supercharged bottom end with ecotec heads think it came across wrong. This has been a cheap build really a turbo Barra would have cost me way more and i wouldn't have learnt anywhere near as much as everything is off the shelf. Main goal was to freshen up on my fabrication skills and learn some tuning on a inexpensive engine. 6 Quote Link to comment Share on other sites More sharing options...
jakesae101 Posted Saturday at 23:13 Share Posted Saturday at 23:13 If you haven’t watched already corn fed boost on YouTube has some fantastic turbo holden 6 content! Quote Link to comment Share on other sites More sharing options...
Muncie Posted Saturday at 23:57 Author Share Posted Saturday at 23:57 Yeah I've been watching Corn fed boosts channel and RK Garage and have been pestering them both on the pcmhacking.net forum hence my car runs with a bit of help from Rhys from RK Garage. This has turned a into a bit of 'a word from my sponsors' HP Academy was a great help too getting my head around the tuning side. Haha as everyone says yeah its just fuel and timing which is true but changing those in a stock PCM is bit harder. Then there's all the other cool shit you can mess with like traction control etc. 1 Quote Link to comment Share on other sites More sharing options...
Muncie Posted Sunday at 20:49 Author Share Posted Sunday at 20:49 Been digging deeper into the PCM and have started tuning the Transmission which shifts almost DSG like now smooth but quickly it's not harsh hopefully this cuts down on heat generation when it's balls out on track. Also ran some logs and adjusted timing in 2 spots where it was detecting knock and pulling timing for a split second with that done it goes great even on just 6psi. Pulled 10% fuel out below 3000rpm 400mg/c which it loved! And hopefully improves fuel economy. Mucked around with traction control so it doesn't do the big belly flop instead it now just retries for traction carries on till it finds it which should soften the driveline impact it used to have and allow it to power on through. Think oil pressure may be dropping off little so next job is to put a gauge on and if necessary shim the relief valve. *edit think ive finally hit the peak of my bell curve learning where it takes me ages to learn new things then I shift into get shit done mode and everything happens quickly and takes little effort. am I ADHD probably...... 6 Quote Link to comment Share on other sites More sharing options...

(assuming I make it) I'm going to say same as you 14s easy 100mph plus easily I've tried using Torque Pro app a few times and aborting run at 200kph due to a corner coming pant shittingly fast. 2 Quote Link to comment Share on other sites More sharing options...
