let the good times begin.....

well as some of you heard i wanted to to a couple things to my m42... well here are some pics...

first... some before pics




removed the upper intake manifol, TB, and some hoses



now i didn't want to remove the lower intake maifold to remove the remainder of the hoses... it was a pain but i got it done.



and here is that mess that the m42 owner know about... i'm going to re-route that mess found on m42club forums




here is the TB swap im working on



going to fab up a custom adapter for it.... i should post up a 3d rendering of it before the weekends end.

also working on a ripoff of MM pulse intake manifold... (for later in the year)



and here is a little something for the m44 motor project i hope to have for late next summer.



good times indeed.

more progress pics to come

Is that an Eaton off a GM 3.8?

Can they really bolt on like that? I assume an Eaton off a GM would be a big block supercharger. Just wondering.. would be nice if they can bolt on with some work. Possibly easier to find one for cheap then searching for a kit online (which seems hard). Btw, beautiful car

yes its from a 1995 buick riviera. its an eaton m62. the m90 is too big

here is some quick info about that charger vs the dasc

DASC uses m45

both m45 and m62 max out at 14000rpm

the m45 at 14000 rpm produces 630 cu meter of air an hr
the m62 at 14000 rpm produces 818 cu meter of air an hr

so pretty much the m62 will produce the same cfm as the m45 but at lower rpm

after some pulley calculations and max engine rpm @ 7000 my m62 will be producing cfm somewhere between the DASC stage 1 and stage 2 but about 2800rpm less than the m45.

less rpm = less heat= more effiecent sc set up

ill go into more details about this build when i start it and its own thread...

Its from the Buick 3.8L that they put in the Park Avenue (nice car) and Riviera's. It made 200 hp with the gen I engine, later Buick sold the rights to that engine to Pontiac and they put in in the Grand Prix GTP and updated the internals of the 3.8 to bring the HP to 240. Its a solid super charger which is very durable and can handle mods.

My buddy had a 98 GTP who ran a 13.8 @ 100 with the car using only a pulley and catback exhaust.

Make sure to change the oil in the snub of the unit when you buy them used.

It won't bolt on. You'll need to remove the upper intake plenum and make an adaptor.

Looks good. The 3.8L blower might be a little big if you're staying stock internals.

Cool. What are your thoughts about using a single butterfly trottle body? Is that from an M50?

I just replaced a bunch of those vacuum lines under the lower intake manifold... if only I didn't need those damn throttle heater elements. They make getting the intake manifold off a pain in the ass!

yeah its from a m50.. not sure.. i almost think it might be restricting. i'll do some math tomorrow after work to figure out the area on both tb openings

meh... take them off... you'll have more power in the winter lol

How much was that supercharger? Just wondering because that sounds like a kick a$$ idea. I'll hopefully be picking up a 325IS tomorrow (Depending on if I can get a tow). Would be sweet if that supercharger could someone get on the 325is engine.

i was just reading that m42club thread about cleaning up the hose mess. I'm going to do it soon when i paint the crankcase cover and intake manifold. can't wait to see what comes from this

i take it you don't need that extra m42 manifold anymore?

i picked it up on kijiji for $100 but keep in mind that after everything is fitted i'm sending it out for a rebuild... as well as the motor. if you do it... do once and right

i think with the 6cyl you might be able to get away with the m90sc you can find them all over kijiji from $100-$300. also keep in mind that i have been researching this sc build for several months. once i was set on how i was going to build it.. then i started with the parts.


ryan.. i'll still take it off your hands if my copy of the pulse intake works out.

dr.zed, after everything is fitted i'm sending the motor and the SC out for a rebuild.

**UPDATE**

failed atempt #1 (because i know there will be more)

i picked up the 5/8" heater hose for the coolent reroute. it only works proper from the rad.. but the engine inlet looks like .5". some people used the 5/8" and just tightened it to fit the .5". i don't trust the hose being crimped so much.

in addition to that the hose was crimping. so i tried this..








that "u" aluminum hose is from the stock set up along with the hose to the head. but as you can see there is still that problem with the 5/8" to .5" or so.

i'm going to look for or make a reducer as another m42 guy did.

i should have an update by tuesday.
