    Cruise Control HELP

    Firstly thanks to the folks to chimed in to help. I rigged up a proof of concept 2:1 reduction for the CC cable and VIOLA it works, I took it for a 30km test run where there is a an uphill gradient that last time I went up there with the PF unit the CC jerked the throttle to point where I...

    Cruise Control HELP

    I replaced the RP with a PF and I still have the same issue, although not as bad. What the CC is doing is letting go of the throttle too much allowing the car to slow then pulling hard enough to kick the trans down. I think the cable movement is too much. I can prevent this by just touching the...

    Cruise Control HELP

    My 4L60e is run by a Megashift and I have normal/sport in normal mode with the 3 4 downshift set at 80% throttle at 100km/h

    Cruise Control HELP

    You got me thinking, so I read the installation instructions for the Rostra 250-1223 and it talks about gain and the need to set this for the engine power. You could be right about the one I have being for a V6 I just bought the PF unit to try.

    Cruise Control HELP

    I had a lump years ago (30 or so) when in my 20's, I originally bought the XJS to LS1 it but after driving it for a while decided to keep the V12. It's been from Perth to Sydney to Brisbane and Melbourne all without CC. I'm a bit loathed to spend money on another CC module, if I can not get...

    Cruise Control HELP

    Hi, I'm not sure if this is right place to post this so if not can a MOD move it to the correct place. A bit of back ground. I have a Jaguar XJS V12 which I removed the inop CC a few years (actually 7years now I think) ago. The car also sports a 4L60e from a VR V8 controlled by a Megashift...

    few questions on supercharging

    Don't buy an M62, it is too small to make decent power on a 3.8L. The Commodores came with an M90. The L67 has different intake manifold and the injectors are mounted in the heads, so to mount the M62 everything would need to be fabricated I think it would be cheaper to buy an M90 with L67...

    Good work, looks very neat. 26.5psi sounds about right I calculated 25psi Whats the youtube link I couldnt find your vid cheers

    !!0 to 100kph times POST HERE!!!

    Weight DUDE the VR is nearly 200kg's lighter than a VZ combine that with the instant lowdown grunt of the Ecotec and good off the line acceleration is pretty well assured.

    FIT's 440RWHP V6 was a turbo L67 with stock internals it is not an N/A stroker. here is a link to the FIT build Forced Induction Technologies - Australia's V6 Supercharged Specialists Anyway the purpose of this thread was a question how much power for $10K with an L36 not how much more...

    How much power for 10 grand

    YEP FIT's 440RWHP VT is still running around. The V6's are good for 500RWHP on stock L67 internals. Much more streetable than an LS1 did you look at the dyno, Most of the V6 Hp is made under 5000rpm and the tourque curve the L67 make way more torque than an LS1 under 4000rpm The Ecotec needs FI...

    How much power for 10 grand

    So your VX SS is making 500WHP here is a dyno sheet from ZZP with an L36 (our Ecotec) making 505WHP look at how quickly that HP climbs your LS1 would need to be making 600+ to keep up. And there are far more powerful Buick V6's try 800hp to well over 2000hp...

    How much power for 10 grand

    Sorry I didnt mean the SC LIM would bolt up to the L36 heads as the machining is different but the castings are the same so if you are going to turbocharge, Ecotec heads are much cheaper than L67 to start with. And can be machined to flow the same I had an LS1 VYII a couple of years ago and...

    How much power for 10 grand

    Had a think about this over night The cheapest option would be to supercharge (Raptor) your existing Ecotec, 300rwhp should be ok on the stock internals if they are in good condition and it is tuned right. Should leave enough dough to strengthen the transmission. Push too far and you will break...

    How much power for 10 grand

    I would use the L36 as the base very cheap to buy a builder. A used L67 would be $2-3K From ZZP L32 Rods $360 set JE Forged pistons $900 HPC would be cheaper and ok for 600hp Rings bearings etc $300 Turbo kit $4000 L36 has the same Block, heads and crank even the camshaft is the same as the...

    [Ecotec] Factory L67 TwinCharged Plans

    I'm pretty sure you can not go over the transmission with the SC still inplace, there is not enough room with the rear intake elbow for the SC, I'll have a look when I get home. I think you would need to go underneath the transmission. Xover and merge under the car connecting to the existing...

    [Ecotec] Factory L67 TwinCharged Plans

    The short answer is the turbo should be equal distance from each manifold. The long answer it is more important how the exhaust pulses get to the turbine, ie pulse timing, pipe diameter, etc, as this has a bearing on how quickly the turbo will spool. In a twincharged setup this is less...

    buick v6

    Do you think it is worth buying a short block from the US or just rebuild an Aussie V6? this will be for an L67

    Isntt that is where the 109 was derived from the 215 aluminum V8 back in the 60's? or did they do it again at a later date?

    Cheers, I have been researching this before I go out and buy a second engine to rebuild, wanted to make sure it would hold up. I was interested to know if it worth purchasing a short block from the USA or just buying an Ecotec Reading through GNTTYPE it said the NA and turbo 109 blocks were the...

    buick v6

    Yeah youre right :banstick: I was always lead to believe they were same, What is the casting number on the VP block I have a VT L67 and it is a bastard to get at while in the car.

    buick v6

    Yeah the L36 are seriesII and the L27 is a seriesI totally different heads This is the same as chev heads there are soooo many different castings I know I have just rebuilt 2 350's and needed a new set of heads the TPI heads were the same but the intake manifold did not fit and needed to be...

    buick v6

    From the research I have done the Blocks were continually improved throughout the life of the engine, the GNX block is a 25526109 casting which is the series 1 came in multiple castings the last iteration being the SG1. The V6 Ecotec is a stageII block these came in on-center and off-center...

    buick v6

    The GNX runs a ladder bar rear end which is why it pops wheelies. The traction in the rear end is awsome. Much better than a VT could ever muster BTW the GNX is 3470lbs 1575kg heavier than a VT exec

    buick v6

    Forgot to add FIT had a VT Super6 they turboed with standard internals (L67) dynoed at 440RWHP pretty close to 600hp at the flywheel and this was on a stock bottomend. Remember the VT is heavier than a GNX the VT if not a Calais would be closer to 3600lbs. The VS is lighter

    buick v6

    The Buick GNX V6 is the same block as the earlier commodore VN to VR, engine codes known as the LD5 LN1 and L27 all shared the same block, BTW the LD5 was in the GNX, VN series1 had the LN1 and the L27 was VN11 through VR. The Series 11 V6 which we in Aus called the Ecotec is known as the L36...

    !!Ford vs holden v6

    I would 2nd that. When I was looking to buy I drove the Force 6, Senator and AMG Mercedes. The 6spd auto in the Force was far superior to the Senator, better ratios and crisper changes, would hold gears and bounce off the limiter. It was not that far behind the AMG 5spd auto. What put me off...

    !!Ford vs holden v6

    Yeah if you plug the numbers into Ray Hall drag calc and add some weight for a driver making the GNX around 1700kg (only 90kg lighter than a BA XR6T mind you) it comes out at a tad over 300hp. Had a look at Drag Times and there are loads of stock GN's running 13.1 to 13.5. The GNX is exactly...

    !!Ford vs holden v6

    The GNX had 488nm of torque and its power figure of 276hp is a little conservative probably closer to 290hp. But its got more to do with how the HP is produced and the torque curve. The Buick V6 develops good HP in the low to midrange RPM. This usually equates to better standing start...
  34. W

    !!Ford vs holden v6

    Yes your power figures are correct but the GNX auto did 0-60mph (97kmh) in 4.7 sec and 13.4 @104mph 1/4 mile. NRMA has the the BA XR6T manual at 6.5 sec 0-100 and 14.9 1/4 mile I would say thats a clean pair of heels to the Buick The GNX was quicker to 60mph and over the 1/4 mile than the...

    !!Ford vs holden v6

    This debate has been raging since Ford and Holden were born, and there is no answer, it comes down to personal preference. The Buick Grand National V6 stock will leave you XR6 turbo for dead so really it is a no win Each has there merit. The Ford has a far better front suspension setup the...

    97 VS s/c6 Calais (factory SC)

    Seems a bit high, to get 200RWKW (300RWHP) for this power it would need intercooler Roller Rockers Headers exhaust CAI and a good tune Really comes down to value for money How much you pay for it. The Super6 is a great engine to mod, responds really well to bolt ons. And in the traffic light...
