I am thinking about buying an Eaton M62 for my VN, I believe they were originally designed for the Buick 3800 engine. Anyone else done this in the past? is it worth it? what kind of power increase is there? What psi would the stock pulley run?
Stock pulley wont do much but I know one that makes 10 psi with a little pulley (suprised me)
i started doing this but then lost interest of it after a while, the hardest part is getting an elbow fabbed up to go from the back of the charger so u can put the existing throttle on, i sourced a charger from the usa when the dollor was good for 200 but postage kills you150 for postage here lol
hmmm i mite have to find myslef another cheap $50 vn again to play around with just as a burnout/basher
Ah cheers Jason, I would have to make another pully then, would I need to update my foam tune if I run about 5-6 psi? also I dont think I will be intercooling it at the moment so whats the max psi I can run without grenading my engine? I am also thinking about doing my heads to go with it.
I've found one in Australia with manifold to suit but its all a matter if its worth it or not lol. I think I iwll need to relocate my idler too and of-course the coilpack.
Anyone else know much about these blowers?I've been doing a little searching but haven't found anything overly helpful for my application.
The question has been asked a couple of times before so a search on here (in VR-VS also) should bring up some of the answers you are after.
I did some measuring when I was looking into using one (M62) and the outlet will end up really close to the firewall with the US manifolds. Also, if it was going to be easy I reckon lot's of people would be doing it - and I don't see that - as the S/C and parts are pretty cheap. It would really help if the S/C housing curved like the VS M90. While cutting and welding the housing might distort it enough to mess up the clearances to the rotors I did consider cutting the end off a housing, machining a step into the cut end and gluing in (epoxy) a custom made end to achieve a similar curve.
There are some internal engine differences between the S/C engine and the NA engine. Most people could probably live with the (small?) reduction in engine durability but it means that the engine balance will be off if using the factory S/C balancer/drive pulley.
The US based forums for the cars that used the S/C will help some - basically you would be doing a S/C conversion as people post about from time to time on them. They'll also help with performance mods. Try under Pontiac Bonneville/Grand Prix, Buick Regatta/Regal, Oldsmobile LSS - I'm sure that you can find the others.

gday, i own a vp 5sp man, with an eaton m62, for sale actually. i bought the kit which came with brackets to relocate coilpacks, and alt i think. had to buy a VS s2 alt, as the earlier one didnt clear the side of the charger. ull want a 70mm throt body aswell. the pipe at the rear of the charger isnt that hard to fabricate, a bit fiddley but any exhaust joint can do it. get a 70mm flange plate laser cut for charger end and for the throt body end. larger inj and dyno tune are a must! ,i run 42lb but l67 inj are fine. u can have the delco dynotuned if u dont have after market ecu. the pulley i have makes a tad over 7psi. any more makes these smaller chargers produce too much heat, and detonate no matter how much fuel u chuck in or how much timtng u take out. the vn motor being n/a have an slight lacking with oil to the bottom end when launching from idle, so build a few revs b4 u take off to get the oil press up a bit. my motor is internally standard unopened in any way, done only 78000ish ks since brand new and makes around 220ish rwhp mabey a bit more, up from bout 115rwhp uncharged. uncooled they do suffer with heat soak after a couple of runs, and more so on hot days and nights, so bad with detonation. if u intercool, go water to air, only coz its easier to modify an m90 water to air than an air to air, and its much cheaper coz u dont need the front mount or piping.no piping= no hesitation or boost drop aswell. i doubt ull find one just for the m62, i couldnt. i also own a vn with an m90 l67 conversion if u have any more questions?
very worth it, if your doing it run a high pressure fuel regulator and im running a small pully witch runs about 10, sounds awsam, if your getting one make sure you buy it as a kit with chip, elbow, fuel rail, injectors, manifold exetra, they would fly passed any side mounts without trouble

hey i was just wondering can i put a eaton m62 on my vp without gettin the ecu tuned like can i use standard injectors and run stock boost ??

I wouldnt suggest a top swap with a M62. The 91-93 Gen II M62s came with a 2.55" pulley. The 94-95 Gen III M62 had Teflon coated rotors and was more efficient so they only put a 2.8" pulley on it. The common swap here in the USA is to topswap the Gen III M62 and run the Gen II 2.55" pulley that should give you about 250-260hp at the crank.
There is one guy who built his own Water to Air intercooler inside of his LIM and he has run as low as a 2.0" pulley. But the charger just gets horribly inefficient if you go smaller than 2.5" and knock becomes a big problem. Most people here swap to the series 2 L67 which is your ecotec motor i believe.
T3/T4 Turbo is the route Im taking with my Buick LeSabre T-Type.
I spose i prolly need to do my research but would it not be easier to use a M90? or are the M62s better cause as far i knew the smaller the number on the eatons the smaller the SC and if you used a m90 the support parts would be more readily available?

yeah, the M62 is smaller then the M90 which would be better. however there isn't a manifold to bolt a M90 to a buick engine as far as i'm aware. maybe you could modify a M62 LIM to fit a M90. then you would run into issues with the fuel injectors, for the M90 fitted to the ecotecs, the injectors are mounted directly into the heads. not sure what the M62 fuel injector setup is

hi there i have put these superchargers on aussia v6 before you would have to run good high octance fuel i just found out they will run on lpg i been doing this for the last 2 to 3 year and done a foo cars now making the elbow is pretty easy when you have done 50 of them if you need any informent email
hi there i have a bluebird with a m62 supercharger and i did have detonation problems till i put some avgas in it and that fix any detanation problems i had i was running 10 to 12 psi boost no detanation problems then its all right if you want to drag it. on the street useing that fuel might be no good for mr police man also i took off the knock sensors and the sensors go s to the echaust manifold
Pics! Pics! Pics! I'd love to see how you do the conversions, particularly wrt the elbow, thermostat housing clearance and cooling system mods, accessory drive - with A/C and power steering - and S/C drive without affecting the engine balance.
I also want to verify the measurements I have for the position of the S/C outlet. I spent a lot of time generating and playing around with a S/C outlet flange mocked up in MDF trying to figure out an acceptable elbow - one without a really nasty change in flow direction.
Complete cars with the S/C V6's are down to a few hundred dollars so even with freight the cost should be reasonable.
hi there if you have a email address i sent you some photo s to you cheers i do sell kit for vn vp with air and power steer
