ok well i have two practical options to choose from
1:the factory eaton m90 supercharger (l67)
2: toyota sc14 supercharger

The SC14 would be the better option out of the two in my opinion, are alot cheaper and easy to come by.

What is your budget?

Have you considered a Raptor Supercharger? They make a pretty decent kit, or maybe even going the turbo route?

out of those 2, the M90 is the better option.
i have heard of people pulling over 20psi out of the little blower. but that takes abit of work to get.

i think there is more after market support with the M90.
make more power then a SC14 could.





are you planning on using a whole L67 or just the blower?
as the blower will only fit on L67 heads and not L37 (ecotec) heads.

This!

But if were going to do this, you may as well do a complete L67 swap over, as the stock ecotec bottom end sucks arse and the L67 bottom end is stronger from factory.

Actually it doesn't mention anything about the motor it's going on.
Only that he is looking at an ecotec supercharger.

But I wouldn't expect you to understand, since that you just purchase other peoples cars pre built on how much "street cred" it will give you....

On topic.

IF the motor is going on a 3.8. putting a supercharger off a motor that was designed for a 2.0 is just fucking retarded.

Its been done many times, there are even kits for it. Usually can do all for about 800-1500

but the SC14 will be out of puff real quick.

gains will not be worth it in the end.

Sc14 would not supply enough air flow top end I would think, seeing tho its meant for a 4cyl..

yeh have experienced an sc14 on a vn and couldnt really feel a difference except for slightly more torque down low, im also aware of the head issues with the m90 plus also the weak bottom ends in the l37, sorry about how vague the topic is guys, ill rephrase:
i have an ecotec(l37) and looking to go down the supercharger path and turbo is a bit too expensive if you do it properly(not backyard nugget) so i have seen sc14s on these motors but unsure of what gains are too be had with such a small charger, also considering the eaton m90 off the l67 however to make this work i would also need the l67 manifold and heads orrr get my head machined to work, and also with the new heads my new extractor setup wwould need to be modified aswell due to the different exhaust ports. so the m90 could very quickly become a very expensive operation, plus also the strain it would place on my standard bottom end,
just looking for any experiance anyone has with either of these chargers and bang for your buck. etc etc
sorry for the huge spiel aswell
cheers :(

if you going to go down the M90 road

you are better off gettin a complete L67, wiring harness and ecu. and dropping that in.
will be much easier.

your exshust should bolt up already if you have an ecotec.


your lookin about $2500 and up for a complete L67 from the wreackers.


it is possible to put L67 heads on a ecotec bottem end, but you will still need to get a L67 wiring harness.
and possibly a custom tune.

also various vortec and raptor blowers that have proven results howover can be a little pricey, ultimately i would spend between 2-3g on supercharging the car but couldnt really stretch that much further then that, i see myself as decently mechanically minded so much of the conversion would be done by myself so that just leaves parts and tune for the budget

i always thought that the intake AND exhaust ports were different, the l67 is seemingly a more viable option. is there any difference in delivery between displacement and centrifugal superchargers? also intercooling options?

the main difference is the L67 injectors are in the head and in the manifold on the L37.



and im about 75% sure that the exshust are the same on b
oth heads.

it is possilbe to get a FMIC on an L67 and theres always the A2W IC kits.

Post #21

I have an L67 calais. It was stock when we got it, not very fast. Replaced the supercharger with a vortech one....much faster.
Don't waste your time with an ecotec, get the L67, much easier to modify a motor that already has the basics done.

Post #22

yeh zac im considering it, now i have the vn i can actually work on the vs without having no car, and upon seeing your dads l67 its pretty much put me onto thinking it could be a cool project, plus the m90 is a pretty stealthy blower and pretty quiet in terms of chargers.
i might hit you up for some parts, or save up some dosh and buy a complete l67 motor :(

atm he's selling this http://cgi.ebay.com.au/Supercharged-V6-L67...b1#ht_500wt_949

http://cgi.ebay.com.au/Holden-supercharged...57#ht_500wt_949

most stuff's polished,he should have other bits left over,i know he got a free set of yt 1.8 ratio roller rockers because they stuffed up and they will fit ecotec which sucks because i wanted them on the calais lol

I'd go for an M112 over an M90. M90 over an SC14.

Sc14 is off the 1ggze straight 6 the smaller sc12 is found on the 4agze
In saying that there both small blowers better off spending te extra getting an aftearket kit ...

i'd love to see a supercharged s-pac,sounds like a good idea,just think when you pull up beside a xr6t you may have a chance lol

have you considered a mace engineering one that bolts on the side of your ecotec?

i was lookin at the after market ones but seem that dropping a whole l67 motor into the car would be more viable(given that the l67 does infact have a stronger big end? :P ) andd the m90 should hhave enough poke to go alright with either a 10 or 12 pound pulley

by the time you spend money for the l67 and fitting etc, better & cheaper to go single turbo kit, but if your set on a super charger go a raptor kit

haha no fucking way, im a holden man through and through, but youll need atleast 3-4k+ to loose by a smaller margin,stock xr6t would destroy a stock L67

look at the fit website, you honestly cant expect to buy an L67 and through a ten pound pulley on it and expect it to make a major difference. by the time u spend 3g+ getting the L67 installed, 1000 for exhaust, 500 for pulley upgrade, your already at 4500g. raptor blower on your orignal ecotec if its healthy will next 180rwkw straight away with exhuast, look up the raptor blower than had in st commodores feature car, ended up making 210-220rwkw with front mount n exhaust. depends also on how healthy your current box diff brakes r etc, things u might want to consider upgrading first
