huh? stop smoking cheap crack!

If you are bothered to do that...

Then why not do something extremely different.. 11L cummins! It will run smoother, make less impact to the world and it WILL make big power and huge torque!

Sound totally stupid now doesn't it!

LOL

The Australian hillclimp championship was won be a Buick V6 powered car (and not the first time either) not to mention the odd circuit lap record - I don't see them jumping to a Cummins anytime soon.

....and to think he pulled a Cosworth V8 out of the car too to replace it with the V6 because he wanted more torque!

i though peter won it again in his super charged vw open wheeler?

Well i personally am not a fan of Bastard engine swaps., ie engine from a different manufacturer

But to go a little against the grain the V6 engine by Buick is quite an animal. For all those slinging crap at it check this one http://www.youtube.com/watch?v=djN94DHkAsA

If we are talking CRAAAAZEEEH engine swaps its simple as far as im concerned.

LS2 + stroker kit + underbonnet screw supercharger with sandwiched water to air cooler in the intake manifold.

- instant torque

- power

- response

- revs its tits off

- would destroy a dyno

- can be driven every day

- will be reliable.

Or a dodge viper V10, your choice. Its shorter than an RB... Saw one fitted into a HQ sedan at the tassie hot rod nationals.

Gary West came out of retirement pulled the car out of the garage and won the title with the normally aspirated Buick V6 powered open wheeler....again.

Pretty sure this car also holds the outright lap record at Barbagello too.

Problem with the positive displacement supercharger on the LS is that they have too much low down torque and sacrifice top end. Mate has one on a Monaro and now he's putting traction control on it. Brother has a twin turbo LS2 and makes more power everywhere from 3200rpm when it hits full boost and is much more tractable than my mates supercharged Monaro.

Depends if you want to do skids or have a fast car I guess.

so the fact that the buick motor was in a car that probably only weighs 700kg has nothing to do with it...... also nothing to do with the fact that it is a 4.2L v6 buick motorsport engine and has no parts in common with the holden v6...... also the v8 it replaced was only 3.0L.

that is like saying the holden v6 is better then the v8's used in the v8 supercars because the lap record of a formula holden lap record is about 8 seconds faster than that of a v8 supercar, despite the fact that the v6 is only putting out about 270kw, in a car that weighs 650kg and has more downforce than the v8 supercar, which puts out over 450kw and weighs about twice as much at 1355kg. but that doesn't mean anything. the v6 must be a better motor because it powers a car that does a faster lap time....... and the 1.6L motor in the formula fords that puts out less than 100kw must be a better motor than the v8's in the commodore and falcon utes because it can lap around eastern creek around 12 seconds a lap quicker. that also has nothing to do with the fact that there is about a 1000kg weight difference between the 2 cars.....

as for that drag car, bit hard to compare that to what is found in the commodores, considering it is bored and stroked out to around 4.5L, runs 2 massive turbos, etc. and there are sr20's running close to that time. and 2jz powered cars are into the 6's, so they are obviously better, and they are smaller.

but the point still remains that bang for buck, a v6 out of a commodore is going to give less power and reliability than a stock rb25.

Yes I agree power to weight and power delivery is everything in motorsport.

Also I believe the Gary West car is a 4.9 litre Buick V6 motor revving to just under 9000rpm.......I guess he could have used an RB.

Stock for stock I think the V6 may have more (or very close) power and torque at 195kw @ 6500 rpm and 340nm @ 2600 rpm, respectively, compared to the RB.

As for reliability and cost....the Commodore and Falcon sixes have spawned a whole race class based on low cost reliable racing. I guess the success of the class speaks for itself.

But if it were my choice I'd slot in a LS2....light, compact, cheap, reliable, economical for the performance with the 6 speed, better overall power curve and huge aftermarket support, plus the stock computer can be tuned to suit some fairly serious levels of mods. Refreshingly simple really.

that is only for the newer alloytech 3.6L v6 (which isn't supercharged), and the better of the 2 versions. the base version is 175kw and 330nm. if you look at the figures for the old 3.8L they aren't as good. the supercharged version only put out 171kw, but had more torque at 375nm, and the NA version is 152kw and 305nm. so if you compare the engine that was originally talked about in this thread, you are looking at a 171kw engine vs 184kw from the rb25. now the torque of the commodore is more, but the other thing to remember is that the rb25 can be tweaked to be making 50 or 60kw more and only be limited by the ecu and turbo. the stock internals will take a fair bit more. in the case of the v6 the stock internals won't take that much more. the other thing to consider is the fact that the supercharged v6 only came in auto form, so you have to go through the hassle of converting it to manual, which isn't as easy as converting other cars (if you want it manual that is).

as for the commodore race series, etc, the engines they use in them are rebuilt, that is why they are reliable. yes there are aftermarket parts that will make them reliable for race use, but the stock parts won't take power increases that well.

i too would either be going an LS2 or RB25/30 or nissan v8. basically anything other than the holden v6

problem is that they are a cast iron block (like the rb series engines), so heavy as hell. also doubt they would fit easily due to them being a longer motor and taller motor and probably wider motor. as well as the gearbox being much bigger.

would be good to see done though. certainly plenty of poke in the motor. especially if done using the new 310kw motor. a flat 565nm of torque from under 2000rpm all the way up to 5200rpm. and in a car that weighs (once you take into account the heavier motor, etc) probably 200 to 250kg lighter than the falcon.

ahahaha, damn you beat me to it. i have a mate with a rx7. seems to be that you don't service them every few months (or 5000kms), you rebuild them, LOL. he once had to rebuild it after 6 months and it hadn't even been started.

apexseals.gif

hey inregards to what u said about rx7, sorry to be out of topic here, but my mates is about to buy an FD rx7, is da car highly maintenance car?? do u have to service it on the spot??

oh no you don't have to service them. you just have to rebuild them both before and after every trip to the shops, LOL.

nah they aren't that bad, just have a reputation as being unreliable once given a hard time. the newer ones are much better.

aaron you are from gympie (like myself) so you should know that the commodore motors are the best and most powerful engine ever made and would be the best conversion you could do to any car, LOL. just ask any of the people who do laps up the street every day.

I reckon a well set up RB25DET would be more than enough , if you can get tyre fryer power out of them in an R33 GTST then it would be same deal in a slightly lighter car and the conversion is straightforward .

I reckon one you break traction big time any more performance is a waste of time and money and probably makes it a lot harder to drive .

I think a street sorted 260 Kw Rb25 - head/cams/inlet manifold/injectors/bolt on turbo/pipes/GTR IC/PFC etc - done .

A .

I think those dissing the Buick V6 fail to realise they wern't designed as a high revving performance motor....so very far from it. Rather a low revving motor with good bottom end torque built to last. For those that know there bikes IMHO there the 'XR' of cars

From experience my ol bunky VN passed along hte generations is still going strong. My m8 has it now with the original motor unopened. reads 400,000km +. He hasnt bothered to change the oil in the last 45,000 (i was the last to change it). This is not the only one i know off.....

After 400,000klm's you never need to do an oil change.....you top the oil up....it leaks out the bottom.....you top the oil up next week...it leaks out the bottom the following week....and so on. New oil every week. :D

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
